Description

Safety device for an adapter for a dome type high pressure butane gas container {Safety device for an adapter for a dome-shaped high pressure butane gas contamer}

The present invention relates to a safety device for an adapter for connecting a dome type high pressure butane gas container. More specifically, anyone in a dome type high pressure butane gas container with a thread formed on the outer circumferential surface of the gas outlet and a dome type butane gas container without a thread formed therein It can be easily combined and used to improve the usability and compatibility of the adapter. Also, when the adapters are combined in the non-threaded dome type high pressure butane gas container, the non-threaded adapter's coupling part is correctly inserted between the support rings so that the safety plate The binding plate must be rotated only when pressed on the support ring to prevent the possibility of safety accidents due to gas leakage and reliability deterioration due to incorrect coupling.

In general, various gas appliances that are portable and moveable are equipped with small gas containers.

This portable gas container mainly uses butane gas container which can be used in normal weather at home or outdoor, and dome type high pressure butane gas container which can be used in different environments such as mountain climbing, unlike its outdoor environment. Although it is manufactured to be divided into the case, in recent years, gas appliances that can be used as a combined regardless of the type of these gas containers are widely used.

At this time, the butane gas container has a long cylindrical container shape, the high pressure butane gas container has a large dome shape to distinguish the use of the container.

In addition, since the biggest difference has a difference in the structure and shape of the jet port for supplying gas, there are many differences in the coupling method with the gas mechanism.

That is, a normal butane gas container has a thin pipe shape of a gas ejection outlet, which is a gas supply means, and presses the ejection outlet toward the inside of the butane gas vessel to supply gas to the connected gas mechanism by opening the gas passage. Do it.

The gas outlet of the dome-type high pressure butane gas container has a very large outer diameter of the gas outlet (pipe-shaped gas outlet) of the general butane gas container having a long container itself, and such a gas outlet has a thread formed at its outer diameter, Some threads are not formed.

Therefore, the gas containers that can be connected and used are classified according to the type of gas appliances, so the connection means cannot be interconnected due to different relations. Therefore, the gas containers can be used only by separately preparing different connection devices for the respective gas containers. There was a problem, such as that, in order to solve this problem, the adapter was required to be connected to each type of gas container can be used regardless of the type.

In the above description, an adapter for a general butane gas container having a thin and long pipe structure, or an adapter for a dome type high pressure butane gas container in which a thread is not formed in a gas outlet having a large outer diameter (Korean Patent Application No. 14578, 1999) There is provided a binding means for selectively detaching the butane gas container and the dome type high pressure butane gas container, respectively, and maintaining the binding state without being released from the combined state.

That is, the two adapters, the body of the gas amount is a high-quality mortar for controlling the discharge of the gas, the nozzle body and the connection hole; A holding means for holding a nozzle provided in itself or in the ejecting opening when the gas ejection opening of the gas container is fitted on the engaging opening of the bottom; A binding plate having a plurality of tangerine pieces as a binding means selectively caught on a locking jaw of the gas container support ring, the binding plate being rotatably installed on the bottom of the body; When the binding plate is rotated on the outer circumferential surface thereof, it is composed of a cam provided with a number of pins to push the engaging piece of the support ring to be caught on the engaging jaw of the support ring as it opens to the outside, and is fixed on the body from the inside of the magazine piece.

However, in such a configuration, since the binding plate is installed so as to rotate freely at a predetermined angle on the bottom surface of the body part and is not provided with a thorough device, the tungsten pieces of the binding plate are usually formed between the pins of the cam. Even if only a slight external pressure is applied, the binding plate is rotated at the bottom of the body so that the tangent pieces protruding at the bottom of the container can be pushed against the cam pins. Therefore, there was a problem in that the binding plate fingering pieces of the adapter did not fit into the support ring of the container.

Therefore, the user checks the position of the fingerings prior to coupling the adapter to the butane gas container. If the fingerings of the binding plate are placed on the upper side of the cam pin and are opened outwards, the user rotates the binding plate to the opposite side by external pressure or the like. After the pivoting pieces of the binding plate, which were rotated and positioned on the cam pins, were positioned in grooves formed between the cam pins, the adapter had to be attached to the container.

However, most users do not check and manipulate this, and thus determine that the product is defective, thereby lowering the reliability of the product itself and immediately requesting after-sales service.

In addition, in the case of the adapter of the dome-type high-pressure butane gas container in which the screw thread is formed in the gas outlet which has a large outer diameter in the above, as shown in FIG. 1, the rod-shaped body in which the gas amount adjustment opening 11 is provided in one side is shown. On the bottom of (1) is provided a coupling hole 13 formed with a female screw 12 that can be coupled to the male screw portion 302 formed on the outer peripheral surface of the gas outlet 301 of the high-pressure butane gas container 300, The nozzle 401 (not shown in the figure because it is coupled to the connector) that can be coupled to the connector 401 of the gas appliance 400 by a screw method is installed.

On the other hand, the adapters that can be coupled to the same domed high-pressure butane gas container are formed differently depending on the shape of the gas outlet (that is, whether or not a thread is formed on the outer circumferential surface of the gas outlet). There is a problem that there is no compatibility.

Therefore, even if the adapter is designed to be used in combination with the same domed high pressure butane gas from the user's side, one or both of them must be purchased in accordance with the shape of the gas outlet of the domed high pressure butane gas container. Therefore, not only does it impose a heavy burden on the consumer economically, but also the gas volume regulator and the nozzle body are provided in the two dome-type high-pressure butane gas container adapters which are separated from each other in response to the shape of the gas outlet, thereby causing unnecessary physical and economic losses. There are also problems such as coming.

The present invention has been devised to solve the above problems, and a threaded dome type high pressure butane gas container adapter having a body having a gas volume control nozzle, a nozzle body, and a coupling unit integrally (hereinafter, abbreviated as a threaded adapter). ), The non-threaded dome-type high pressure butane gas container connecting adapter (hereinafter abbreviated as non-threaded adapter) can be selectively used to improve the usability and compatibility of the adapters. It is possible to, but any external pressure is normally applied to the binding plate, including when installing the safety plate between the body of the non-threaded adapter and the binding plate to rotate the adapter to couple the non-threaded adapter to the threaded adapter. Even if the binding plate does not rotate freely from the body, Since the pieces are located on the upper side of the cam pin and open outwards, a part of the bottom of the non-threaded adapter is misinserted into the support ring of the container, thereby preventing the possibility of a safety accident due to gas leakage and a decrease in reliability of the product. An object of the present invention is to provide an adapter for connecting a domed high pressure butane gas container.

The safety plate (6) having a configuration in which the stepped portion (63) integrally protruded into the engaging hole of the binding plate (4) is integrally projected to one side of the tack piece (62) together with the spring (7). The safety plate 6 is installed on the installation groove 24 so as to be moved up and down, and at a position corresponding to the installation groove 24 located above the rotation limit hole 45 outside the binding plate 4. The stepped portion 63 of the predetermined number of engaging holes 46 to be hooked selectively It is characterized in that the left and formed.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the two adapters having the structure as described above are first manufactured to use the gas mechanism 400 by being coupled to the dome-shaped high pressure butane gas container 300 that can be used in the highlands, and the gas outlet 301 of the high pressure butane gas. ) The threaded adapter 100 for direct coupling to the male threaded portion 302 formed on the outer circumferential surface and the threaded portion are not formed on the outer circumferential surface of the gas outlet 301 so that the binding plate 4 and the cam 5 Milffin 52 is divided into a non-threaded adapter 200 of the configuration that can be used by coupling to the support ring 303 of the high-pressure butane gas container 300.

At this time, the threaded adapter 100 is already known, and description of its configuration and working relationship will be omitted.

In addition, the non-threaded adapter 200 is also known, but can be used in combination with the screw adapter (100) in combination with the domed high-pressure butane gas container 300 irrespective of the shape of the gas outlet (301). Part of the structure is improved so that (ie, the gas amount adjusting device 11 is already provided in the threaded adapter 100, so it is removed, and when used independently, the connecting device 32 which is coupled to the gas appliance 400 is used. To be coupled to the coupler 13 of the threaded adapter 100 in a screw fastening method), and has a structure in which a safety plate 6 is installed between the body 2 and the binding plate 4.

That is, the non-threaded adapter is almost the same as the conventional one in the basic configuration, and the arc-shaped installation groove 24 into which the safety plate 6 and the spring 7 are fitted is provided at one side of the bottom surface of the body 2 at a predetermined depth. The safety plate 6 is installed so as to move up and down on the installation groove 24 by installing the arc-shaped safety plate 6 and the spring (7), the safety plate 6 of the installation groove 24 Formed by bending in an arc shape to correspond to the shape and the upper center portion is formed with a spring settling groove 61 is fitted with one end of the spring (7), the bottom portion in the center of the pressing paper selectively pressed on the support ring 303 of the container 300 The piece 62 is formed to protrude, and one side of the tack piece 62 is manufactured so as to have a configuration in which the stepped portion 63, which is fitted into the locking hole of the binding plate 4, is integrally formed to protrude integrally. The inside of the rotation limit hole 45 of the binding plate 4 is usually in the above. It is to form a plurality of engaging holes 46 at regular intervals so that the stepped portion 63 of the front plate 6 is selectively fitted.

Therefore, normally, the stepped portion 63 of the safety plate 6 is in a state of being fitted into the locking hole 46 of the binding plate 4 by the elastic force of the spring 7, as shown in FIG. Rotate each other to couple the non-threaded adapter 200 to 100, or the binding plate 4 is not rotated even if any force is applied to the binding plate 4 from the outside, the binding plate ( 4, the tungsten pieces 44 are maintained in the space between the pins 52 of the cam 5, as shown in Fig. 5 so that the outer diameter of the tungsten piece 44 is the inner diameter of the support ring 303 of the container It can be easily inserted into the support ring of the container since it will remain smaller or nearly the same.

On the other hand, when the threaded portion 302 is formed on the outer circumferential surface of the gas ejection opening 301 of the domed high-pressure butane gas container 300 to be used, the coupling port 13 of the threaded adapter 100 is used as the gas ejection opening 301. ) May be used by directly coupling to the screw connection method, and in the case where there is no thread on the outer periphery of the gas outlet 301, the connection port of the non-threaded adapter 200 to the coupling hole 13 of the threaded adapter 100 is used. (32) is combined to be integral with each other, and then press the bottom of the non-screw type adapter 200 to the support ring 303 side of the container, the tangy piece protruding to the bottom of the binding plate (4) The 44 and the cam 5 are fitted between the support ring 303 of the container and the gas outlet 301.

At this time, the holding member 62 of the safety plate 6 protruding outward through the locking hole 46 of the binding plate 4 is the support piece 303 of the container and the cam finger piece 44. And when fitted between the gas outlet 301 is pushed against the upper surface of the support ring 303, the safety plate 6 receives the elastic force of the spring (7) as shown in Figure 6 and the installation groove 24 having a predetermined depth The stepped portion 63 of the safety plate 6 is pushed into the inside and exits from the catching hole 46 of the binding plate 4.

Accordingly, the binding plate 4 is rotatable in the bottom portion of the connection medium 3 fixed integrally to the non-threaded adapter 200 body 2, in which the user binds the binding plate 4. Holding the handle (42 or four) of the handle (42) formed in the rotation in one direction, or by pressing the handle 42 portion of the binding plate 4 to the container side by rotating the adapter itself when the binding plate (4) or the body (2) and the cam (5) is rotated within a predetermined angle range (that is, the length of the arc-shaped rotation limit hole 45 formed in the binding plate 4) of the binding plate (4) Since the edge pieces 44 integrally injection-molded at the bottom are opened to the outside while riding up the outer surface of the pin 5 of the cam 5, the outside of the edge pieces 32 is a gas outlet 301 as shown in FIG. 7. A hook formed inside the support ring 303 of the dome-type high-pressure butane gas container 300 in which a thread is not formed on the outer circumferential surface thereof. Because be hanging two adapters 100, 200 to 304 will be fixed firmly to the binder itself, weather for butane gas of the domed.

At this time, the stopper 43, which is caught on one side of the pin 10 of the cam 5, protrudes from one side of the finger piece 44 of the binding plate 4, so that the handle 42 of the binding plate 4 is formed. By pushing the part to one side or rotating the adapter body itself, the bombardment pieces 44 can be prevented from riding over the mil pins 52 when they are spread out on the outside of the mil pins 52 of the cam 5. have.

On the other hand, since the gas amount adjusting opening 11 is installed in the middle portion of the gas guide hole 15 of the threaded adapter 100 body 1, the two adapters 100 and 200 are coupled to the container as described above. In addition, the user can properly open and close the gas control opening 11 to properly adjust the discharge of the gas supplied to the gas appliance.

In addition, when the two adapters are to be separated from the high-pressure butane gas container 300 at the same time, when the binding plate 4 is rotated in the opposite direction as described above, the tangy pieces 44 protruding from the bottom thereof are cams 5. Departure from the mil pin 52 of the movement to the groove formed between the mil pin 52 and at the same time the stepped portion 63 of the safety plate 6 is coincided with the engaging hole 46 of the binding plate 4, At this time, since the tungsten piece 44 is returned to its original state by its restoring force, it is separated from the locking step 304 of the support ring 303 to separate the adapter itself into a butane gas container, and the adapter as described above. Since the holding force of the pressing piece 62 and the support ring 303 is lost when the plate is separated, the safety plate 6 is returned to its original state by the restoring force of the spring 7 installed in the installation groove 24. The jaw portion 63 is inserted into the catch hole 46 of the binding plate 4 again. Since it is possible to limit the free rotation of the binding plate (4).

As described above, according to the present invention, a non-threaded adapter having a shape without the gas amount adjusting mechanism can be selectively used in a threaded adapter having a body having the gas amount adjusting mechanism, the nozzle body, and the coupling unit integrally. Safety plate is installed to improve the usability and compatibility of the adapter, and that the binding plate itself does not rotate freely from the body even if any external pressure is normally applied between the body of the non-threaded adapter and the binding plate. Since the binding plate is rotated due to external pressure, it is possible to prevent the bullet pieces from spreading outwards by the cam's mill pin, which prevents the possibility of safety accidents due to gas leakage due to deterioration of the reliability of the product due to the incorrect binding of the adapter. It is a very useful design.
