The door panel sealing member clamping groove 12 is provided on the inner side of the door panel 11. A clamping plate 111 is fixedly provided on the outer side of the door panel 11. A first fixing hole 121 is provided on the inner side of the door panel sealing member clamping groove 12.
[0022] The sealing frame 2 includes a door frame 21 and a door frame sealing member slot 22 . The door frame sealing member slot 22 is provided on the inner side of the door frame 21 . A connecting hole 221 is provided on the inner side of the door frame sealing member slot 22 . A door frame fixing bolt 211 is inserted into the door frame 21 .
[0023] The civil air defense door sealing structure is provided with a door panel seal 13 and a door frame seal 23. The door panel seal 13 is designed as a convex arc structure, and the door frame seal 23 is designed as a groove arc structure. The door panel seal 13 and the door frame seal 23 can be perfectly snapped together, thereby improving the reliability of the seal. The door panel seal 13 and the door frame seal 23 are increased in contact area by the housing structure, thereby improving the impact resistance of the door panel seal 13 and the door frame seal 23 when the civil air defense door is closed, thereby extending the service life of the civil air defense door using the sealing structure. The door panel 11 and the door frame 21 are both provided with snap grooves, which can be tightly snapped together with the door panel seal 13 and the door frame seal 23, thereby avoiding the possibility of leakage at the seal connection. The seals are fixed with bolts for easy maintenance and replacement.
[0024] Furthermore, the sealed door 1 also includes a door panel seal 13 and a first fixing bolt 14. The first fixing bolt 14 is inserted into the inner side of the door panel seal 13. The door panel seal 13 is clamped into the inner side of the door panel seal slot 12. A sealing ring 131 is fixedly provided on the inner side of the door panel seal 13.

A rotating shaft 333 is inserted into the hinge 33, and both ends of the rotating shaft 333 are inserted into the inner side of the splint 111.
[0028] It is particularly important to emphasize that the door frame fixing bolt 211 passes through the door frame 21 and is threadedly inserted into the inner side of the wall 31 .
[0029] Working Principle: First, the air-defense door sealing structure is designed with door panel seals and door frame seals. The two sets of seals cooperate with each other to achieve a sealed effect.
[0030] Secondly, the door panel seal is designed as a convex arc structure, and the door frame seal is designed as a groove arc structure. The arc structure makes the two sets of seals tightly connected, and the sealing effect is better;
[0031] Finally, the arc-shaped structural design greatly increases the contact area between the seals. The large contact area not only improves the sealing performance, but also improves the impact resistance of the civil air defense door when it is closed.
[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
