Description

PUSH TYPE DRAIN HOLE OPENING AND CLOSING APPARATUS}

The present invention relates to a switchgear for opening or closing drains used in various drainage facilities, such as sinks, bathtubs, sinks, etc. More specifically, the stopper according to the pressing operation on the inner passage (draining hole) of the support frame fitted to the drain It is easy to use and easy to install by fixing the operation port of simple structure that repeats the opening and closing of the door to the drainage port. And it relates to a push-operated drain opening and closing device easy to maintain.

In general, where water, such as a sink, a bath, a sink, etc. are used, a drain for draining water after use is provided. Such a drain is provided with a drain opening and closing device to control the drain pipe. The function of the drain opening and closing device is to take a tub as an example. When the bath is performed, the drainage can be closed to store water in the bathtub, and when the water is to be drained, the drain and opening are opened to open the tub and the drain pipe. Done. An example of this is shown in FIGS. 1 and 2.

1 is a perspective view showing the structure of a general bathtub, Figure 2 is a cross-sectional view of the drain portion shown in FIG.

As shown, the stopper 20 made of an elastic body was inserted into the drain hole 12 of the conventional tub 10 to close the passage of the drain hole 12. At this time, the stopper 20 used was a simple disc or hemispherical rubber stopper. And, by making a groove or a hook or the like on the top of the stopper 20 so that the user can easily grasp and pull out from the drain 12 to open the drain 12 more easily.

However, when the elastic stopper 20 is tightly fitted to the drain 12 or completely adhered to the drain 12 by a little water, it is difficult to easily open the drain because it is not easily separated from the drain. Even when the rubber stopper 20 enters into the drain 12, it would occur. In this case, a plumber called a plumber to disassemble and repair the drain pipe. In addition, when opening the drainage port, the stopper separated from the drainage should be kept separately in another place, but the stopper is frequently placed anywhere, so there is a high risk of loss.

In order to solve this problem, a drain opening and closing device has been devised to open and close the drain according to the position of the stopper is installed in the drain, an example thereof is disclosed in Figs.

3 is a cross-sectional view showing the structure of a conventional push-operated drain opening and closing device, Figure 4 is an exploded perspective view showing in detail the core portion of FIG.

As shown in the drawing, the support shaft 72 fixes the guide cylinder 60 in the drain 52 of the drainage main body 50 with screws 54 and supports the stopper 70 to the guide cylinder 60. ) Is inserted to freely move in and out in the up and down direction, and is coupled to a thrust lock mechanism 80 which is an up and down driving means installed inside the guide cylinder 60. The thrust stroke mechanism 80 is a mechanism used to enter and leave a pen nib, such as a ballpoint pen. As shown in FIG. 4, a fixing ring 82 is fixed to an upper portion of the support shaft 72 and the fixing ring 82. It is composed of a rotary ring 84 is coupled to the bottom of the 82 and inserted on the support shaft 72 to be able to move up and down a predetermined distance, and the engaging projection 62 and the guide groove 64 formed in the guide cylinder 60 Lose. The fixing ring 82 and the rotation ring 84 are engaged with the teeth 82a and 84a formed at the corresponding surface portions thereof, respectively, and the locking jaws (90 ° apart from the outer circumferential surface adjacent to the teeth 82a and 84a). 82b and 84b) are formed.

Accordingly, when the stopper 70 is pushed, the support shaft 72 descends and the locking jaw 82b of the fixing ring 82 descends to the lower side of the guide groove 64, and the locking jaw 84b of the rotary ring 84 is pushed down. Will be pushed out. At this time, the teeth 84a of the rotary ring 84 are moved by sliding in the teeth 82a of the fixing ring 82 by the elastic force of the spring 86 pushing the rotary ring 84. In this state, when releasing the stopper 70, the support shaft 72 is raised by the restoring force of the spring 86, and the locking projection 84b of the rotary ring 84 is the projection protrusion 62 of the guide cylinder 60. As a result, the support shaft 72 stops at the lowered position while the ascending stops, thereby closing the drain hole 52 by keeping the stopper 70 fixed to the upper end of the support shaft 72 in the down state.

Of course, when the stopper 70 is pressed once more, as the teeth 84a of the rotary ring 84 rotate from the teeth 82a of the fixing ring 82 as described above, the locking jaw 84b of the rotary ring 84 is guided. It is located in the guide groove 64 of the 60, when the hand is released in this state is released and the locking jaw 82b of the fixing ring 82 and the rotary ring 84 by the restoring force of the spring 86, 84b) as the support groove 72 and the stopper 70 ascend along the guide groove 64, the stopper 70 is to open the drain 52.

The conventional push-operated drain opening and closing device described above is complicated in structure because many components are combined as described above. In particular, the fixed ring and the rotating ring is formed with teeth and engaging jaw respectively in the corresponding portion, the structure is complicated, making the manufacturing difficult and the manufacturing cost increases. In addition, while the teeth and the locking jaws of the fixing ring and the rotating ring of the plastic is engaged with the wear occurs badly there was a disadvantage that the durability is poor. Moreover, since the guide cylinder coupled to the stopper and holding the support shaft is completely fixed to the drainage body with a screw, it is difficult to install and detach the stopper from the drainage hole, which makes it difficult to assemble and to clean the drainage hole.

Therefore, the object of the present invention is to devise to solve the above-mentioned drawbacks, the simple structure of repeating the opening and closing of the stopper according to the pressing operation on the inner passage (drainage hole) of the support frame fitted to the drain hole. It is easy to use and easy to install by fixing and inserting the operation port into the drain. In addition, when the elastic support frame is pulled out from the drain, it can be easily removed, so it is easy to clean and maintain the drain pipe. To provide.

Therefore, the integrated drain opening and closing device is inserted and fixed while being in close contact with the drain port 200 by the elasticity of the elastic support frame 500 by pressing the drain port 200.

Since the drain 200 generally forms a circular space, the support frame 500 inserted into the drain 200 is also cylindrical and designed to have the same diameter as the drain 200 so that its outer diameter can be fitted to the drain 200. do. The inside of the support frame 500 forms a drain hole 510, and the top of the drain hole 510 is provided with a stopper accommodating part 512 in which the drain plug 300 is entered. The stopper receiving portion 512 is formed to a depth that can be lowered by pressing a certain portion of the stopper 300 accommodated. In addition, a flange portion 520 is formed at the upper end of the support frame 500 and is caught when inserted into the drain 200. In this case, the bottom of the flange portion 520 is in close contact with the corresponding bottom surface of the bathtub 100. It becomes as formed as it is possible to maintain confidentiality. On the outer circumferential surface of the lower support frame 500 of the flange portion 520, a gentle inclined portion 530 connected from the flange portion 520 is provided. The inclined portion 530 is inclined to a narrower diameter toward the downward, and facilitates the insertion of the support frame 500 when inserting the support frame 500 into the drain 200, as well as with the inner surface of the drain 200 Good adhesion ensures confidentiality.

In the interior of the support frame 500, the fixed blade 540 protrudes from the inner wall toward the shaft center, and the operation tool 400 is fixed to the inner end thereof. Therefore, the operation tool 400 is located on the center of the drain hole 510 of the support frame 500 spaced apart from the inner surface of the support frame 500, thereby supporting the outer surface of the operating tool 400 and The inner surface of the mold 500 forms a space in which water can flow. The space through which this water can flow becomes a substantial drainage path. In the present embodiment, two fixed blades 540 are disposed on both sides of the operation tool 400. Of course, the fixed blade 540 is at least one or more, but the number that can be fixed to the inside of the support frame 500, the operating tool 400 is sufficient, it is preferable to configure at least one pair left and right for stability.

The support frame 500 having the above-described structure may be made of rubber as a whole, or a method of packing the whole surface of the drainage hole and the contact portion of the drain hole with rubber, which is an elastic body. When the whole is made of rubber, it has a disadvantage in that its elasticity is large, so that insertion and extraction are easy, but the firmness is slightly insufficient. In addition, when the fixed wing 540 and the fixing cylinder 550, etc., which require strength, are made of plastic and the portion of the contact portion with the drain port 200 is made of rubber, the desired strength can be maintained, but there is a problem in that the manufacturing cost increases. Therefore, it is preferable that the material of the support frame 500 is selected and configured according to the use.

By inserting the support frame 500 integrated with the drain plug 300 into the drain port 200, the inner hole of the support frame 500, that is, the drain hole 510 becomes a substantial drain hole through which water is drained. The drain plug 300 is provided with a rubber packing 310 on its main surface so that water is not leaked through the drain hole 510 by maintaining watertightness in the drain hole 510 in the support frame 500 when it is closed. The lower end portion is coupled to the operating port 400 for raising or lowering in the drain hole 510 in the support frame 500 and fixed to the position to open or close the drain hole 510. The operating port 400 is inserted into the support frame 500, the operating body body 410 is fixed to the fixed blade 540 and, so pressed by the operating body body 410 fixed to the support frame 500 is lowered And the locking operation, and once again is provided with a lifting piece 420 to release the latch is lifted. The upper end of the elevating piece 420 is coupled with the drain plug 300 so that the drain plug 300 is also elevated in accordance with the elevating operation of the elevating piece 420. Of course, the operating port 400 is provided with the components for causing the lifting piece 420 to engage in the lowering position to close the drain hole, which will be described in detail with reference to FIGS. 8 and 9. The lower end of the operating body 410 is also attached to the filter plate 402 located in the drain 200 to filter foreign matter such as hair. Because of the filter plate 402, foreign matters, etc. do not flow into the drain pipe, thereby preventing the drain pipe from being blocked.

Actuator 400 is provided with an actuating body 410 that is inserted into the support frame described above and joined as shown. The operating body 410 is composed of a case 430 fixed to the fixed blade end of the support frame described above, and a guide cylinder 440 mounted in the case 430. The guide groove 432 is formed in the vertical direction of the case 430. The guide grooves 432 are arranged around the inner circumferential surface of the case 430 and are arranged at equal intervals. In this embodiment, four guide grooves 432 are spaced apart at intervals of 90 °. In particular, the guide groove 432 is bent into a crank in the driveway 432a to be inserted, it is formed to be eccentric. A mounting hole 434 is drilled in the bent access road 432a of the pair of guide grooves facing each other among the guide grooves 432. At the bottom of the case 430, a support protrusion 436 supporting the spring 450 protrudes from the center of the case 430, and the fixing holes 438 are drilled outward. The fixing protrusions 442 formed at the lower end of the guide tube 440 are inserted into the fixing holes 438.

The guide cylinder 440 is accommodated in the case 430 and fixed, and the outer diameter thereof is smaller than the inner diameter of the case 430, and a constant space 412 is formed therebetween. The lifting piece 420 is inserted and lifted into this space 412. The lower end outer circumferential surface of the guide tube 440 is formed with a flange portion 441 having a diameter corresponding to the inner diameter of the case 430 to be stably seated in the case 430, the outer side of the flange portion 441 The fixing protrusions 442 protrude. In addition, an operating space 443 is formed inside the guide cylinder 440, and the lifting grooves 444 are formed at regular intervals around the inner circumferential surface thereof. The lifting grooves 444 are formed at the end of the double engaging jaw 445 connecting the lifting grooves. The double locking jaw 445 has a sawtooth shape having two inner and outer inclined surfaces, and a locking end is formed at the middle portion thereof. The double locking jaw 445 and the lifting groove 444 and the components that operate in association with it will be described in detail later with reference to FIG. 9.

The driving member 460 enters the operating space 443 of the guide cylinder 440. The drive member 460 is composed of a cylindrical outer cylinder 470 and an inner cylinder 480 which is inserted below the outer cylinder 470 and is caught to flow at a small interval in the axial direction thereof. In order to combine the inner cylinder 480 and the outer cylinder 470, the inner cylinder 480 has a circumferential outer circumferential surface and an outer locking protrusion 482 protrudes, and the inner circumferential surface has a circumference in the outer cylinder 470 corresponding thereto. 472 protrudes. In addition, the lower end of the inner cylinder 480, the inclined protrusions 484 are protruded at equal intervals around the outer peripheral surface. Therefore, when the inner cylinder 480 enters the outer cylinder 470 from below, the outer locking protrusion 482 is caught so as not to be separated downward while passing through the inner locking protrusion 472. At this time, the inner cylinder 480 is caught in the lower end of the inclined protrusions 484 at the lower end of the outer cylinder 470 is no longer able to enter, the interval between the inclined protrusion 484 and the outer locking projections 482 is By slightly longer than the interval between the inner locking protrusion 472 and the lower end of the outer cylinder 470, the inner cylinder 480 in the outer cylinder 470 can be moved slightly up and down. The inclined protrusion 484 of the inner cylinder 480 is in contact with the bottom of the outer cylinder 470, the tooth 474 is formed on the bottom of the outer cylinder 470 in contact with. The inclination angle of the teeth 474 is formed to match the inclination angle of the inclined protrusion 484, and the allowable distance in the vertical direction of the inner cylinder 480 from the outer cylinder 470 described above is the inclined protrusion (from the teeth 474). 484 moves up and down as much as the mountain height of the tooth 474 allows the inclined protrusion 484 to move along the tooth 474. Inner cylinder 480 is particularly the upper surface is blocked, the spring 450 is entered into the inner cylinder 480 is always elastically supporting the inner cylinder 480 in the upward direction. The outer cylinder 470 penetrates up and down, and a flange portion 476 is formed at an upper end thereof. The flange portion 476 is fitted to the inner upper end of the elevating piece 410 to fix the outer cylinder 470 inside the elevating piece 410. In addition, the elevating protrusions 478 protrude in the vertical direction on the outer circumferential surface of the outer cylinder 470 and are fitted into the elevating grooves 444 in the above-described guide cylinder 440 to thereby elevate.

The lifting piece 420 is inserted into the guide grooves 432 of the case 430 by the protrusions 422 protruding from the lower end thereof. Accordingly, the lifting piece 420 can be stably elevated in the vertical direction in the case 430. The elevating piece 420 is mounted on the outside of the driving member 460, and enters the space 412 formed between the case 430 and the guide tube 440 when entering the operating body 410. The lifting piece 420 rises or falls in this space 412. As described above, the guide protrusions 422 of the elevating piece 420 are inserted into the guide grooves 432 by rotating after entering the access path 432a of the case 430. The inserted guide protrusions 422 are thus inserted. The finishing piece 490 is mounted on the upper portion of the case 430 so as not to be separated from the crank guide groove 432. The finishing piece 490 closes the access path 432a bent from the guide groove 432 by inserting the fixing angles 492 provided at the bottom into the access path 432a to make the guide groove 432 straight. At this time, at the ends of the pair of fixing angles of the four fixing angles 492, the projections 494 protrude outwards to be fixed to the mounting holes 434 of the case 430. Then, the access protrusions 432a of the guide grooves 432 are closed so that the guide protrusions 422 cannot be separated, thereby preventing the lifting piece 420 from being removed from the case 430. The drain plug 300 is fixed to the upper end of the elevating piece 420, for this purpose, a bolt hole 424 is formed on the upper surface of the elevating piece 420. The bolt hole 424 is fastened to the fastening bolt 320 provided on the bottom surface of the drain plug 300 to couple the drain plug 300 and the lifting piece 420.

10 is an operation explanatory diagram for explaining the operation of the present invention.

In this figure, in order to explain the locking of the above-mentioned drainage stopper (drainage opening position) from the lowering position (drainage closing position) and the operation of releasing the lock to return from the closed position to the open position, the configuration associated with this Only elements are shown schematically. Therefore, the lower locking operation and the release raising operation of the driving member in the guide cylinder will be described in detail with reference to this drawing.

When the drain plug is in the ascending position, that is, in the drain opening state, the driving member coupled to the lifting piece is located on the inside of the guide cylinder. At this time, the elevating protrusions 478 of the outer cylinder of the driving member are inserted into the elevating grooves 444 of the guide cylinder, and the lower inclined protrusions 484 of the inner cylinder which are in contact therewith are also in the elevating grooves 444. It will be located at. The elevating groove 444 is substantially equal to the width of the elevating protrusion 478 and the inclined protrusion 484 so that when the inclined protrusion 484 and the elevating protrusion 478 are located in the elevating groove 444, the inclined protrusion 478 484 is not completely engaged with the tooth 474 and is in contact with the inclined surface of the proximal end thereof.

Accordingly, in this state, when the spring is compressed while elastically supporting the inner cylinder by pressing the drainage stopper, as the lifting piece descends, the tooth 474 of the outer cylinder descends while pushing the inclined protrusion 484 of the inner cylinder, and as a result, the lifting groove 444 The inclined protrusion 484 is moved from the inclined protrusion 484 is moved along the inclined surface of the teeth 474 from the I position to the II position. In this state, when the force holding the drain cap is removed, the driving member is raised by the restoring force of the spring. At this time, the inner cylinder of the driving member does not rise because the inclined protrusion 484 is caught on the double catching jaw 445, and thus the outer cylinder does not rise, but as small as the mountain of the tooth 474 according to the coupling clearance with the inner cylinder. The distance will rise. Accordingly, the inclined protrusion 484 is released from the tooth 474 and is slid along the inner inclined surface 445a of the double locking jaw 445 to be caught by the locking end 445b in the middle thereof. In this way, the inclined protrusion 484 of the inner cylinder is caught in the intermediate locking end 445b of the double locking jaw 445 of the guide cylinder and fixed in the lowered position, so that the rising piece and the drain plug combined with the driving member are actuated in the operating body. It is fixed to the lowered position. This state is a state where the drain plug is closing the drain hole.

When the drain plug is pressed once more to open the drain hole closed by the drain plug, the drain plug is slightly lowered, and the tooth 474 of the outer cylinder pushes down the inclined protrusion 484 of the inner cylinder. Accordingly, the inclined protrusion 484 hanging on the intermediate locking end 445b of the double locking jaw 445 is released from the double locking jaw 445 to ride the outer inclined surface 445c of the double locking jaw 445 at position III. It slides and moves to position IV. Then, the locking of the driving member is released, and thus the elevating protrusion 478 of the outer cylinder and the inclined protrusion 484 of the inner cylinder are raised along the elevating groove 444. As a result, the driving member, the lifting piece and the drain plug coupled thereto are raised to open the closed drain hole.

Now, the operation of the present invention will be described in detail with reference to the above-mentioned drawings.

First, the installation method of the device will be described. If the device is integrated into the drain 200 of the bathtub 100, the installation is simply completed. In more detail, the elastic support frame 500 is placed on the drain port 200 by pressing a force from above after placing the support frame 500 which is an elastic body in close contact with the inner wall of the drain port 200. At this time, the inclined portion 530 of the support frame 500 is inserted in close contact with the inner wall of the drain 200, the tub 100, the flange portion 520 of the support frame 500 is in contact with the upper end of the drain 200 (100) When it comes in close contact with the bottom surface, mounting of the device is completed. Then, the drain port 200 and the cylindrical support frame 500 is in close contact with each other to maintain airtightness. Therefore, the water in the bathtub 100 is introduced into the drain pipe through the drain hole 510 in the support frame 500 to be drained. As such, when the support frame 500 is fixed to the drain port 200, the operation tool 400 fixed by the fixing blades 540 is joined therein, and the drain plug 300 is disposed on the upper part of the operation port 400. ) Will be combined.

Thus, since the support frame 500 integrated with the drain plug 300 is inserted into the drain hole 200, the drain plug 300 is pulled upwards when cleaning, repairing or replacing the drain hole. The support frame 500 in which the drain plug 300 and the operation port 400 are integrated within the 200 is simply separated and separated.

Next, how to use the apparatus will be described.

In order to receive the water in the tub 100, first, the drain hole 510 of the support frame 500 communicating with a drain pipe (not shown) should be closed with a drain cap 300. To this end, when the user presses the drain plug 300, the lifting piece 420 of the operating port 400 coupled with the drain plug 300 by the force is lowered in the operating body 410. . Then, the driving member 460 mounted inside the elevating piece 420 is also lowered integrally while compressing the spring 450 supporting it, wherein the elevating protrusions 478 of the outer cylinder 470 and the inner cylinder ( The inclined protrusions 484 of the 480 are lowered along the elevating grooves 444 of the guide tube 440, and the inclined protrusions 484 are inclined along the inclined surface of the teeth 474 when the inclined protrusions 484 are out of the elevating grooves 444. 484 slides and moves to the double locking jaw 445. As a result, the inclined protrusion 484 of the inner cylinder 480 is caught by the double locking jaw 445, the lifting force of the drive member 460 to rise by the elastic restoring force of the spring 450 is blocked. In this state, the inclined protrusion 484 is located at the locking end 445b formed at the center of the double locking jaw 445. In this way, the drain plug 300 is fixed in the lowered position to close the drain hole 510 in the support frame 500. Thus, the water may be used to receive water in the bath 100 in a state in which the drain hole 510 of the bath 100 is closed.

After using the water is to drain the contaminated tub 100 water through the drain hole 510, in order to do so by pressing the drain plug 300 from above. Accordingly, the drain plug 300 is moved slightly downward, and the outer cylinder 470 of the elevating piece 420 and the driving member 460 integrated therewith is slightly moved downward, thereby guiding the cylinder 440. The teeth 474 of the outer cylinder 470 are pushed down by the inclined protrusion 484 of the inner cylinder 480, which is caught by the intermediate locking end 445b of the double locking jaw 445. When the inclined protrusion 484 is released from the middle engaging end 445b of the double locking jaw 445 by the lowering of the inclined protrusion 484, the inclined protrusion 484 is slid along the outer inclined surface 445c into the next lifting groove 444. The inner cylinder 480 and the outer cylinder 470 are raised by the elastic restoring force of the spring 450 elastically supporting the inner cylinder 480. As the driving member 460 is raised, the lifting piece 420 and the drain plug 300 coupled thereto are also raised to open the drain hole 510 which is closed. The water in the tub 100 is drained to the drain pipe through the open drain hole 510.
