[0011] The advantages of the utility model compared with the prior art are:

[0012] 1. When encountering an impact, the main crush box undergoes plastic deformation of wrinkles in cooperation with the main crush guide groove, thereby absorbing the impact energy, reducing the damage caused by the impact to the civil air defense door body, protecting the hinged parts of the civil air defense door body and the door frame, and ensuring the normal use of the civil air defense door.

[0013] 2. The secondary crush box supplements the energy absorption effect of the main crush box, improves the energy absorption effect of the main crush box, improves the ability to absorb impact force, and improves the protection effect of the civil air defense door body.
