[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the sealing structure on the current flip-up civil air defense door is mainly composed of a square sealing frame and a sealing rubber pad installed on the sealing frame, although this sealing structure can meet the sealing requirements of the flip-up civil air defense door when it is closed, since the sealing structure mentioned above is mainly fixed by screwing bolts when installed on the civil air defense door, the process of screwing bolts is relatively cumbersome, which leads to the inconvenience of installing the sealing structure of the above structure on the civil air defense door, which is not only inconvenient for efficient installation and use of the sealing structure of the civil air defense door, but also inconvenient for convenient disassembly and maintenance of the sealing structure of the civil air defense door when it is damaged in the later stage. The new design of the slot, limit hole, pull slot, pull plate, spring and limit column can make it possible to quickly insert the limit frame into the slot by pulling the limit column out of the slot in advance when installing the limit frame. After the limit frame is inserted into the slot, it is only necessary to loosen the pull plate to allow the limit column to be inserted into the limit hole under the action of the spring, thereby realizing rapid limit fixation of the limit frame after insertion. Since the tedious operation of tightening the bolts is avoided in the above-mentioned installation method, the limit frame can be disassembled and assembled more quickly, which not only facilitates the efficient installation and use of the civil air defense door sealing structure, but also facilitates the convenient disassembly and maintenance of the civil air defense door sealing structure in the later stage.
