This application relates to an impact-resistant double-layer air-raid shelter door, belonging to the technical field of double-layer air-raid shelter doors. The main body of the double-layer air-raid shelter door includes an outer door panel, a front door panel, a rear door panel, and two slots. The rear door panel is fixed inside the right slot, and the rear end of the front door panel is connected to the left slot. The front wall of the cavity of the left slot is provided with an anti-pressure component. The anti-pressure component includes multiple sets of connecting blocks, multiple sets of compression blocks, multiple sets of buffer springs, a connecting rod fixedly installed on the opposite side of the upper and lower connecting blocks, and a pressing rod fixedly installed and hinged to the front end of the two compression blocks in the same set. This impact-resistant double-layer air-raid shelter door, by providing an anti-pressure component, can mitigate the impact force received by the double-layer air-raid shelter door, reducing the probability of deformation or even damage due to impact force, thereby increasing the service life of the double-layer air-raid shelter door. It can buffer the impact force in stages to further improve the buffering performance and facilitate the maintenance and repair of the anti-pressure component.
