Civil air defense door with high impact strength
The invention provides a civil air defense door with high impact strength, which relates to the field of civil air defense doors and comprises a main door body, the main door body is hinged to an outer door frame, a lower sliding frame is slidably arranged on the lower portion of the main door body, a back sliding frame is slidably arranged on the back of the main door body, a lower cushion block is slidably arranged in a groove in the lower portion of the outer door frame, and a tail rack is fixedly arranged at the tail of the lower cushion block. A front inserting block is vertically and slidably arranged on the front side of the lower portion of the outer door frame, a clamping and stopping frame is arranged on the front portion of the lower cushion block, and the front inserting block and the lower inserting block are both locked with the outer door frame in an inserted mode, so that the main door body and the lower portion of the outer door frame obtain higher impact strength. The situation that the impact strength is short due to the fact that the threshold height is reduced is avoided, and the problem that after the threshold height is reduced, the impact strength value between the lower portion of the door frame and the civil air defense door is reduced to become a short plate of the overall strength is solved.
本发明提供一种抗冲强度高的人防门，涉及人防门领域，包括：主门体，所述主门体铰链连接外门框，主门体下部滑动设置有下滑架，主门体背部滑动设置有背滑架，外门框下部凹槽滑动设置有下垫块，下垫块尾部固定设有尾齿条，尾齿条和中齿轮啮合连接，中齿轮中部和外门框转动连接，外门框下部前侧垂直滑动设置有前插块，下垫块的前部设置有卡止架，前插块和下插块双重和外门框插接锁定，使得主门体和外门框下部获得更高的抗冲击强度，避免因缩减门槛高度导致的出现抗击强度短板的情况，解决了门槛高度削减后，门框下部和人防门之间的抗冲强度数值降低成为整体强度的短板的问题。
