Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figures 1 to 6 As shown, an explosion-proof civil air defense door comprises: a door body 1, a shock absorbing and buffering component 2 and a mineral wool 3, wherein the door body 1 comprises a front steel plate 101, a rear steel plate 102, a partition steel plate 103 and an inclined steel plate 104, wherein the rear steel plate 102 is arranged on the rear side of the front steel plate 101 and its edge is fixedly connected to the front steel plate 101 by welding the side steel plates, the partition steel plate 103 is arranged between the front steel plate 101 and the rear steel plate 102 and is fixedly connected to the side steel plates, and the partition steel plate 103 is fixedly connected to the front steel plate 101. There is a hollow buffer layer between the partition steel plate 103 and the rear steel plate 102, and there is a solid buffer layer between the partition steel plate 103 and the rear steel plate 102. The inclined steel plate 104 is fixedly connected between the front steel plate 101 and the rear steel plate 102. The inclined steel plate 104 divides the hollow buffer layer and the solid buffer layer into multiple buffer bins 105. The shock-absorbing and buffering assembly 2 is arranged on the inner side of the buffer bin 105 of the hollow buffer layer, and the mineral wool is filled on the inner side of the buffer bin 105 of the solid buffer layer and on the inner side of the buffer bin 105 near the edge of the side steel plate in the hollow buffer layer.

[0032] The shock absorbing and buffering assembly 2 includes a damping tube 201, a damping rod 202, a spring 203, a damping tube 204, a damping rod 205, a fixing block 206, a support rod 207 and a spring 208.
