A pair of upper and lower dampers 2 is rotatably installed in a rectangular damper body 1 connected in the middle of the air duct, and the pair of upper and lower dampers 2 is connected to a damper shaft 3 via a link 4 or the like. It is designed to be rotated integrally. A gear box 5 is provided at one end of the damper shaft 3, and is externally operated by an operation handle 7 provided at the other end of the operation shaft 6 via a worm gear mechanism provided between the damper shaft 3 and the operation shaft 6. Is configured so that the damper 2 can be rotated to adjust the air volume.

[0003]

[Issues to be solved by the device]

 The conventional air volume adjustment damper has the operation handle 7 as described above, and has a structure in which it is manually operated directly from the outside. On the other hand, this type of air volume adjustment damper is often installed in a high place such as the upper part of a machine room or a parking lot, and a stepladder or ladder is used for its manual operation, or another pipe or other pipe is used. The fact is that they are operating by climbing on ducts, etc., and they had a dangerous defect.

The present invention has been made to solve the above-mentioned problems, and it is possible to use a stepladder, a ladder, or the like even for an air volume adjustment damper provided at a high place. It is an object of the present invention to obtain an operation device of an air volume adjustment damper that can be operated without climbing up by pipes or ducts.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, an operating device for an air volume adjusting damper according to the present invention includes a damper rotatably installed in a damper body, and the operating shaft and the operating handle supported by the damper body are provided in the damper. In the air volume adjustment damper that rotates the damper from the outside by operating the operation handle to adjust the air volume, the operation of the air volume adjustment damper installed at a high place is provided at the tip with a linking portion for the operation handle. It is characterized in that a rotation operating portion is provided at the other end of the work rod.

Further, the operation rod is configured to be adjustable in expansion and contraction in the length direction.

[0007]

[Action]

 The operating device of the air volume adjusting damper according to the present invention is configured as described above. Therefore, when operating the air volume adjusting damper installed at a high place, the air flow adjusting damper provided at the tip of the operating rod is used. Operate the air volume adjustment damper installed at a high place from a distant floor surface by directly rotating the rotary operation part at the other end of the operation rod after linking with the operation handle of the adjustment damper. You can

Further, since the operating rod is configured to be adjustable for expansion and contraction, regardless of the height position of the air volume adjusting damper installed at a high place, the expansion and contraction adjustment of the operating rod allows the operation rod to be operated by one device. Can be operated easily.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a configuration diagram of an operating device of an air volume adjusting damper. FIG. 2 is an operation state explanatory diagram in which the operating device is used for the damper main body 1 arranged below the slab 11 and between the pipe 12 and the cable 13. The configuration of the air volume adjusting damper is the same as the conventional one described above, and the description thereof is omitted here. The operation device of the air volume adjustment damper can operate the operation handle 7 provided at the other end of the operation shaft 6 of the air volume adjustment damper from a distant position, and the tip of the operation rod 8 having a predetermined length dimension. Is provided with a bifurcated linking part 9 that can be linked to the operating handle 7, and a rotary operating part 10 that can rotate the operating handle 7 by manually operating the operating rod 8 at the other end. It has a different configuration.

The operating rod 8 may simply be a rod having a constant lengthwise dimension, or a small-diameter portion 8a that is telescopically fitted so that the lengthwise dimension can be adjusted. It may be composed of the large diameter portion 8b and the expansion and contraction adjusting screw portion 8c.

However, according to the above-described embodiment, when operating the air volume adjusting damper installed at a high place, when the operating rod 8 is capable of adjusting the lengthwise dimension, the length is most suitable for operating. After adjusting the length, the bifurcated linking portion 9 provided at the tip of the operating rod 8 is linked to the operating handle 7 of the air volume adjusting damper, and then the operating rod 8 is moved as shown in FIG. By directly and manually rotating the rotary operation unit 10 provided at the other end, the operation handle 7 linked to the operation rod 8 is rotated, and the air volume adjustment damper is operated via the operation handle 7. It can be performed.

Therefore, even if the air volume adjustment damper is installed at a high place such as an upper part of a machine room or a parking lot, it is necessary to easily operate the air volume adjustment damper from a position on the floor away from the machine to adjust the air volume. You can In particular, in the case of the operation rod 8 configured to be adjustable in expansion and contraction, the air volume adjustment damper is operated from the floor surface position by adjusting the length by expanding and contracting the operation rod 8 regardless of the height position of the air volume adjustment damper. be able to.

[0013]

[Effect of device]

 As described above, according to the air volume adjusting damper operation device of the present invention, even if the air volume adjusting damper is installed at a high place, it can be easily operated from a remote floor position. It is not necessary to use a stepladder or a ladder, or to climb by using other pipes or ducts, and the danger associated with the operation of the air volume adjustment damper can be eliminated. In addition, the air volume adjustment damper itself does not need to be modified according to the installation height in order to facilitate its operation, and the productivity of the air volume adjustment damper can be increased.
