When the lower end of the gear lever 41 extends out of the gear tube 4 under the action of the elastic force of the return spring 42 and abuts against the ground, the locking spring 44 ejects the end of the locking piece 5 out of the locking hole 43, so that the gear lever 41 and the gear tube 4 are fixedly connected.
As shown in fig. 4 and 6, a pull rope 40 is arranged between the lower end of the gear lever 41 and the second driving lever 3, the lower end of the pull rope 40 is fixedly connected with the lower end of the gear lever 41, a fixed pulley positioned right above the gear tube 4 is rotatably mounted on the back of the door plate 1, and the upper end of the pull rope 40 extends into the accommodating cavity 2 after bypassing the fixed pulley and is fixedly connected with the second driving lever 3. The elastic force of the fourth buffer spring 31 is larger than that of the return spring 42, and the second driving rod 3 pulls the pull rope 40 to move away from the gear tube 4 in a natural state, and at this time, the lower end part of the gear rod 41 is retracted into the gear tube 4 under the common traction of the second driving rod 3 and the pull rope 40.
When the second anti-collision plate 32 is driven by the impact force to retract the second driving rod 3 into the accommodating cavity 2, the pull rope 40 moves towards the direction close to the gear rod 41 under the action of the elastic force of the return spring 42, the lower end part of the gear rod 41 is ejected out of the gear tube 4 under the action of the return spring 42, and finally the lower end part of the gear rod 41 is abutted against the ground, and the gear rod 41 can support the door plate 1 from the back of the door plate 1, so that the stability and the firmness of the front of the door plate 1 are ensured when the front of the door plate 1 is impacted.
The implementation principle of the civil air defense door capable of resisting high-strength shock waves provided by the embodiment of the application is as follows: when the front surface of the door plate 1 receives high-intensity shock waves, the first driving rod 22 positioned on the impact surface compresses the first buffer spring 23 under the pushing of the shock waves, and at the moment, the first buffer spring 23 can play a better role in buffering and damping the door plate 1, so that the impact of the high-intensity shock waves on the door plate 1 is relieved, and the impact surface of the door plate 1 is better protected. Along with the first driving rod 22 is retracted into the accommodating cavity 2 under the pushing of the shock wave, in the process, the first driving rod 22 pushes the end part of the bolt piece 24 around to be ejected out of the accommodating cavity 2 through the linkage assembly 25, and finally the end part of the bolt piece 24 is inserted into a through hole preset on the door frame, and the connection strength of the door panel 1 and the door frame is further enhanced through the mutual insertion of the bolt piece 24 and the door frame through hole. And the larger the impact force received by the first driving rod 22, the tighter the bolt piece 24 is inserted into the through hole of the door frame, the further locking of the door plate 1 and the door frame is realized by means of the impact force, the conversion of the impact force is realized, the connection strength of the door plate 1 and the door frame is ensured, the situation that the door plate 1 and the door frame are separated when the high-strength impact force is received is effectively prevented, and therefore the high-strength shock wave resistance of the door plate 1 is improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
