Description

Technical Field

[0001] This utility model relates to the field of air defense door opening technology, and more specifically, to an auxiliary opening device for air defense doors. Background Technology

[0002] Civil defense doors are the entrances and exits of civil defense projects. Civil defense doors are generally quite heavy, some weighing several tons or even tens of tons. The heavier civil defense doors are more difficult to open. When closing, personnel can push them closed. The auxiliary opening device for a civil defense door described in publication number (CN216714172U) is that by directly pulling the zipper, both the pull plate and the small gear rotate. The rotation of the small gear drives the rotation of the large gear, which in turn drives the rotation of the large gear, making it easier to open. The large gear drives the corresponding tooth block to rotate through the rotating rod, and the tooth block drives another tooth block to rotate through the toothed rod, thereby rotating the winding drum. The winding drum winds up the steel wire rope, thus achieving the purpose of easily opening the civil defense door.

[0003] When the above-mentioned device is in use, the zipper can be pulled directly when the air-raid shelter door needs to be opened, which increases the convenience of opening the air-raid shelter door. However, the steel wire rope is exposed to the outside for a long time, which is prone to corrosion and breakage during use, posing a significant safety hazard. In addition, the operation of closing the air-raid shelter door is relatively cumbersome. At the same time, this method is slow to open the air-raid shelter door, thus affecting the convenience of opening the air-raid shelter door. Utility Model Content

A steel wire pull rope is provided on the outer end face of the steel rope winding component. A mounting hook is provided on one side of the steel wire pull rope.

[0007] In a preferred embodiment, a limiting pull block is provided at one end face of the main body of the air defense door, and an air defense door installation support block is provided on one side end face of the main body of the air defense door;

[0008] The support slide rod passes through the middle of the air defense door mounting block and the air defense door mounting support block, and extends into the interior of the first auxiliary box, where a support limiting block is provided.

[0009] In a preferred embodiment, a rotating support rod is provided in the middle of the supporting limiting block, a second bevel gear is provided on one end face of the rotating support rod, and a first reduction gear is provided at the end of the rotating support rod away from the second bevel gear;

[0010] A first auxiliary motor is provided on the outer end face of one side of the first auxiliary housing. The output shaft of the first auxiliary motor passes through one end face of the first auxiliary housing and extends into its interior. A second reduction gear is provided on the output shaft of the first auxiliary motor inside the first auxiliary housing.

[0011] In a preferred embodiment, there are two of the air defense door mounting support block, the first auxiliary box and the air defense door mounting block, and they are arranged in an array on both sides of the transverse central axis in the main view direction of the air defense door body.

[0012] The limiting pull block is engaged with the installation hook, and the air defense door installation support block and the support slide rod are connected and fixed by the provided nuts.

[0013] In a preferred embodiment, the first bevel gear and the second bevel gear are adapted to each other through gear meshing, and the first reduction gear and the second reduction gear are adapted to each other through gear meshing.

[0014] In a preferred embodiment, both the first auxiliary motor and the second auxiliary motor are connected to an external control device. The second auxiliary mounting plate is fixed to the wall by bolts. The number of mounting holes is multiple and arranged in an array on the end face of the second auxiliary mounting plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In practical use, this invention, through the provision of a second auxiliary motor, a reduction gearbox, a steel wire rope, and an installation hook, allows for convenient operation of the steel wire rope via the second auxiliary motor. Simultaneously, with the limit block and installation hook engaged, the steel wire rope can be easily pulled by the second auxiliary motor, reducing the difficulty for operators in opening the air-raid shelter door. After the air-raid shelter door is opened, the installation hook can be removed from the limit block, protecting the steel wire rope and preventing long-term exposure from affecting its stability. Furthermore, with the corresponding meshing of the second reduction gear, the first reduction gear, the second bevel gear, and the first bevel gear, the first auxiliary motor can drive the support slide rod to rotate, assisting in opening the air-raid shelter door and effectively increasing its opening speed.
