[0028] The implementation principle of a light alloy structure civil air defense door in the embodiment of the present application is:
[0029] When the explosion warning information is received, the reinforcement rod 3 is rotated so that the reinforcement rod 3 rotates toward the door leaf 2 and fits against the door leaf 2. The reinforcement rod 3 reinforces the door leaf 2, and the door leaf 2 is reinforced by the reinforcement rod 3; then the extension rod 7 is rotated, and the extension rod 7 is connected to the reinforcement rod 3 on the same side, and then the cross bar 8 is clamped in the installation groove 12, and the diagonal brace 13 is rotated to support it to the ground. When the explosion shock wave is transmitted to the door leaf 2, the door leaf 2 has a tendency to deform toward the reinforcement rod 3. Under the action of the reinforcement rod 3, the extension rod 7 and the cross bar 8, the above tendency is buffered, thereby reducing the possibility of deformation of the door leaf 2 and improving the deformation resistance of the civil defense door.
