| description | The utility model relates to the technical field of civil air defense doors, in particular to a civil air defense door with a buffering and shock-absorbing structure. A buffering and shock-absorbing assembly is arranged on the door frame and comprises a buffering top plate, spring dampers, a distance increasing expansion plate and a gap filling pad, the spring dampers are evenly fixed to one side of the buffering top plate, the distance increasing expansion plate is fixed to the other side of the buffering top plate, and when one side of the door frame is impacted, the gap filling pad is arranged between the buffering top plate and the distance increasing expansion plate. If the distance-increasing expansion plate is stressed firstly, the gap filling pad buffers the distance-increasing expansion plate, meanwhile, the distance-increasing expansion plate is prevented from colliding with the door frame suddenly, the buffering top plate further performs jacking, and then the spring damper performs second-part buf |
