Example 1

3 to 6, the damping damper 20 of the [Example 1] according to the present invention was configured as follows.

Body 27 is formed integrally with the conventional case 4 and the frame 12, but the frame 12 is formed so as to project more than a predetermined width to the outside than the slope of the case (4).

Fixing the fixing plate 5 in the horizontal direction inside the body 27 and a plurality of damper blades (8) in which the shaft (9) is fixed to the lower side of the fixing plate (5) is installed upright, but the shaft (9) fixed plate It was made to protrude upward while penetrating (5).

One end of the link 24 is fixed to each of the protruding shafts 9, and the other end of the link 24 is connected to the connecting shaft 25 by a freely rotating shaft 26 and one of the shafts 9. To the rotary shaft of the motor (6) by the operation of the motor 6 when the shaft (9) connected to the rotary shaft of the motor 6 is rotated all the damper blades (8) at the same time interlocked and rotated.

One side of the motor 6 is provided with a switch (not shown) for operating the motor (6).

In addition, a bending panel 35 is installed at a lower end side of the damper blade 8, and a through hole 38 corresponding to the shaft 9 of each damper blade 8 is formed at the bending panel 35, and the shaft 9 is provided. ) Was sequentially inserted into the bush 36, the through hole 38 and the bush 37 so that the rotation of the shaft 9 was supported by the bent panel 35 and the bush 36, 37.

The door 21 bends both upper and lower ends, but forms a through hole 32 and a through hole 33 facing the upper and lower ends of the body 27 and the upper and lower ends of the door 21, respectively. By inserting through the (33) to open and close the door 21 around the round bar (34).

The louver plate 22 has a rectangular shape in which a plurality of ventilation holes 23 are formed, and both ends thereof are bent inward to form a bent portion 39.

A through hole 29 is formed at an upper end of the bent portion 39, and a long hole 28 corresponding to the through hole 29 is formed at a lower side of the fixing plate 5 in the body 27, but the long hole 28 is formed. Silver to have a long diameter in the vertical direction and penetrates the bolt 30 through the through hole 29 of the louver plate 22 and the long hole 28 of the body 27, and then tightened with a nut 31 to fix the bolt 30. The louver plate 22 was opened and closed about the center.

When the nut 31 is fastened to the bolt 30, the bolt 30 is moved along the long hole 28 to open and close in the up and down direction when the louver plate 22 is opened and closed by tightening loosely.

According to the damping damper 20 as described above, if the damping damper 20 is installed on the wall 19 and the switch is turned on, the amount of air discharged while all the damper blades 8 rotate left and right by the motor 6 and It is possible to adjust the direction, and when cleaning the inside of the damper or repairing a malfunction, the louver plate 22 may be raised and then cleaned or repaired.

Example 2

As can be seen in Figure 7 the damping damper (20-1) of the [Example 2] according to the present invention is the same as the following [Example 1], but the bent portion at the upper and lower ends of the louver plate (22-1) 40 to form a through hole (not shown) in the bent portion (40) and a long hole (not shown) facing the through hole formed in the bent portion (40) fixed plate (5) and the body (27) It is formed on the bottom surface of the bolt 30 through the through hole of the louver plate 22-1 and the long hole of the body 27 and then fastened by fastening the nut 31 to the louver plate (centered around the bolt 30 ( 22-1) was opened and closed in the left and right directions.

Of course, the same effect as that of [Example 1] is obtained by the above [Example 2].

Example 3

The damping damper of [Example 3] according to the present invention will be described with reference to Figs.

Figure 9 is an exploded perspective view of another embodiment of the smoke damper according to the present invention, Figure 10 is an exemplary view of the front door closed in another embodiment of the smoke damper according to the present invention, Figure 11 is in accordance with the present invention In another embodiment of the damper damper is an illustration of the front door open state.

9 to 11, the damping damper of [Example 3] newly includes a fixed plate 5, a lever 44, a working plate 46, and two front doors 55 and 56. .

The fixing plate 5 forms a through hole 41 into which two rectangular through portions 42 and the shafts 9 of the respective damper blades 8 are inserted at predetermined intervals, and connected to the respective rectangular through portions 42. By forming the engaging piece 43 double bent to the lower side and the inner side to enable the operation plate 46 to be described later to slide in the front and rear direction along the engaging piece 43.

The lever 44 is fixed to the shaft 9 between the upper end of the damper blade 8 and the fixing plate 5, and the shaft 9 fixed to the shaft 9 is connected to the motor 6, and the lever 44 At the end, the operating rod 45 was fixed to allow the operating rod 46 to move the operating plate 46 to be described later in the forward and backward directions by the rotation of the lever 44 rotating together with the shaft 9.

The operating plate 46 is a rectangular plate 47 and the blade piece 51 is formed integrally, the rectangular plate 47, the operating rod 48, after the operating rod 45 is inserted into the operating rod 45 in the horizontal direction Forming an axis receiving space 49 in which the shaft 9 is accommodated when the operating plate 46 is moved back and forth from the end portion, and a bent engaging portion 50 that slides along the locking piece 43 at the both ends. Wing piece 51 is formed at both ends thereof with long holes 53 and 54 into which actuating rods 63 and 64 of front doors 55 and 56 are described later. The front doors 55 and 56 can be opened and closed by being moved forward and backward by the 45.

The front door 55 and the front door 56 were installed in place of the louver plate 22 of the above [Example 1], and the shapes thereof were line symmetrical shapes.

The front doors 55 and 56 have bent portions 57 and 58 that are bent inwardly at upper and lower ends thereof, and through-holes 59 are inserted with shafts (not shown) at ends of the bent portions 57 and 58. ) 60 and each of the bent portion (57), (58) is fixed to the support piece (61) 62 and the support piece (61) (62) double bent inward and inward and the wing piece (51) By integrally forming the operating rods 63 and 64 respectively inserted into the long holes 53 and 54 of the above, the moving rods 63 and 64 are moved back and forth by the operating plate 46. The front doors 55 and 56 were opened and closed.

When the motor 6 is operated and the shaft 9 rotates, the damping damper rotates the lever 44 and the operating rod 45 together with the shaft 9 at the same time.

Rotation of the actuation rod 45 is made by pushing the actuation plate 46 along the actuation rod movement hole 48, and at the same time the actuation plate 46 pushes the actuation rods 63, 64 and eventually the front door. 55 and 56 will be opened.

Air is also discharged with the opening.

As described above, the damping blade damper according to the [Embodiment 3] can not only interlock all damper blades 8 by the operation of the motor 6, but also the front doors 55 and 56 with the damper blades 8, respectively. Simultaneous interlocking with each other means that the air is not affected by the resistor at all.

As can be seen from the above-described damping damper according to the present invention, by forming the case 4 and the frame 12 as one body 27, installation and transportation of the damping damper is simplified, and all damper blades ( 8 is provided with a link 24 and a connecting bar 25 installed on the upper side of the fixing plate 5 to be interlocked to minimize the resistance when the air is discharged and the appearance is beautiful, a plurality of ventilation holes (23) By installing the louver plate 22 formed thereon so that opening and closing is possible, the inside of the smoke removal damper can be easily cleaned or repaired. Also, the front doors 55 and 56 are interlocked with the damper blade 8 to open and close at the same time. By doing so, it completely eliminates the resistance to air in the discharge of the air.
