Abstract
The utility model provides a civil air defense engineering airtight door with anticollision structure relates to civil air defense door field. The civil air defense engineering airtight door with the anti-collision structure comprises a door body, a right side fixedly connected with spring of the door body, a right end fixedly connected with anti-collision plate of the spring, a left side fixedly connected with fixed rod of the anti-collision plate, and a groove is formed in the right side of the door body. This civil air defense engineering airtight door with anticollision structure, through the spring, the crashproof board, the dead lever, a groove, mutually supporting of steel pipe and blade, it at first can touch the crashproof board to reach the impact, crashproof board can cushion through extrusion spring this moment, crashproof board can drive the blade through the dead lever and remove left simultaneously, the blade can cut off the steel pipe, with this carry out the energy-absorbing, the buffering that auxiliary spring provided carries out the better protection door body, it relies on its thickness to provide the protecting effect completely to have solved current civil air defense engineering airtight door, but in case outside impact is too big, the yielding problem that loses the protecting effect even of airtight door.
Description
Technical Field
The utility model relates to a people's air defense door technical field specifically is a people's air defense engineering airtight door with anticollision structure.
Background
People's air defense engineering also calls people's air defense engineering, it is the underground protective building that is built alone for guaranteeing personnel and material shelter, people's air defense commander, medical aid during the war to and combine the basement that can be used for air defense during the war that ground building built, need set up the airtight door in the people's air defense engineering in the position of safe room, be used for protecting the crowd of taking refuge, current people's air defense engineering airtight door relies on its thickness completely to provide the protective effect, but in case external impact is too big, the airtight door is yielding or even loses the protective effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a civil air defense engineering airtight door with anticollision structure has solved current civil air defense engineering airtight door and has relied on its thickness completely to provide safeguard effect, but in case outside impact is too big, the airtight door is yielding or even loses the problem of protection effect.
Technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a civil air defense engineering airtight door with anticollision structure, includes the door body, the right side fixedly connected with spring of the door body, the right-hand member fixedly connected with anticollision board of spring, the left side fixedly connected with dead lever of anticollision board, the right side of the door body is seted up flutedly, fixedly connected with steel pipe between the top end inner wall of recess, the left end fixedly connected with blade of dead lever, the left side of blade and the right side overlap joint of steel pipe.
Furthermore, a movable hole communicated with the right side is formed in the left side of the door body, and a balance rod is movably connected inside the movable hole.
Furthermore, the right end of the balance rod is fixedly connected with the left side of the anti-collision plate.
Furthermore, a baffle is fixedly connected to the left end of the balance rod, and the right side of the baffle is in lap joint with the left side of the door body.
The utility model provides a civil air defense engineering airtight door with anticollision structure. The method has the following beneficial effects:
this civil air defense engineering airtight door with anticollision structure, pass through the spring, the crashproof board, the dead lever, the recess, mutually supporting of steel pipe and blade, it at first can touch the crashproof board to reach the impact, crashproof board can cushion through the extrusion spring this moment, crashproof board can drive the blade through the dead lever and remove left simultaneously, the blade can cut off the steel pipe, with this carry out the energy-absorbing, the buffering that the helper spring provided carries out the better protection door body, it relies on its thickness to provide safeguard effect completely to have solved current civil air defense engineering airtight door, but in case outside impact is too big, the yielding problem that loses the protection effect even of airtight door.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of a portion a of fig. 1 according to the present invention.
The anti-collision device comprises a door body 1, springs 2, an anti-collision plate 3, a movable hole 4, a baffle 5, a balance rod 6, a fixed rod 7, a groove 8, a steel pipe 9 and a blade 10.
Detailed Description
As shown in fig. 1-2, the embodiment of the utility model provides a civil air defense engineering airtight door with anticollision structure, including the door body 1, the right side fixedly connected with spring 2 of the door body 1, the right-hand member fixedly connected with anticollision board 3 of spring 2, movable hole 4 that is linked together with the right side is seted up in the left side of the door body 1, the inside swing joint of movable hole 4 has balancing pole 6, the right-hand member of balancing pole 6 and the left side fixed connection of anticollision board 3, the left end fixedly connected with baffle 5 of balancing pole 6, the right side of baffle 5 and the left side overlap joint of the door body 1, the left side fixedly connected with dead lever 7 of anticollision board 3, recess 8 has been seted up on the right side of the door body 1, fixedly connected with steel pipe 9 between the top end inner wall of recess 8, the left end fixedly connected with blade 10 of dead lever 7, the left side overlap joint of blade 10 and the right side of steel pipe 9.
The working principle is as follows: when striking to crashproof board 3, the impact that crashproof board 3 received can extrude spring 2 and cushion, and crashproof board 3 still can drive blade 10 through dead lever 7 simultaneously and cut off steel pipe 9, further absorbs energy at the in-process of cutting off steel pipe 9 for reduce the striking dynamics.
