[0012] Preferably, the rubber roller comprises a hard rotating shaft, a flexible sleeve is coaxially arranged on the outer wall of the rotating shaft, and the sleeve is in rolling contact with the upper end surface of the base.
[0013] The utility model proposes a building structure for civil air defense buildings, which has the beneficial effects of: a sealing plate is arranged at the bottom of the civil air defense door and is rotatably arranged through a hinge, and a rubber roller is rotatably arranged at the bottom of the sealing plate. When the civil air defense door is opened or closed, the rubber roller is in rolling contact with the base, which is convenient for pushing and pulling the civil air defense door. After the door is closed, the knob can be rotated to push the wedge block to move. When the wedge block moves, the sealing plate rotates and moves downward, and the rubber roller is stored in the installation groove. At this time, the sealing plate is close to the ground to achieve sealing. In addition, due to the existence of the rubber roller, the opening and closing of the civil air defense door is more labor-saving and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
