There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment.

[0003] In the existing technology, civil air defense doors do not have a buffer structure. If they are subjected to a large impact force during wartime, they can generally only rely on the hardness of the civil air defense door's own material to resist, which makes the door body of the civil air defense door easily damaged and reduces its protective performance. Therefore, we have launched a civil air defense door with impact resistance. Utility Model Content

[0004] The purpose of the utility model is to provide a civil defense door with impact resistance, which can greatly improve the buffering performance of the civil defense door when it is subjected to impact force, has strong protective performance and high reliability, and increases the service life of the civil defense door, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
