The invention relates to the technical field of civil air defense engineering, and discloses a civil air defense safety protection airtight door. A sliding groove is formed in the rear side wall of adoor body, and an adjusting wheel is clamped in the sliding groove in a left-right sliding manner; a gear ring is fixedly arranged on an annular wall of a rotary disc, and an eccentric shaft is vertically and fixedly arranged at one side of the front side wall of the rotary disc and rotationally penetrates through the middle of the adjusting wheel through a bearing; an output shaft of a driving motor is fixedly sleeved with a gear, and the upper side of the gear is meshed with the gear ring; guide strips are symmetrically and fixedly arranged on the left side wall and the right side wall of the door body, and ratchets are symmetrically and fixedly arranged on the left side wall and the right side wall of each guide strip; a second rotating shaft is rotationally arranged in a groove througha bearing, the second rotating shaft is fixedly sleeved with buckles, and the other ends of the buckles and the ratchets are clamped; and due to an automatic adjusting manner, the door body is more convenient to open and close, the occupied ground space is reduced, the damage resistance of the door body is improved, meanwhile, the door body is effectively prevented from falling, and the overall safety performance of the device is improved.
一种人防安全防护密闭门，本发明涉及人防工程技术领域，门体的后侧壁上开设有滑动槽，滑动槽的内部左右滑动卡设有调节轮；转盘的环壁上固定设置有齿环，转盘的前侧壁一侧垂直固定设置有偏心轴，偏心轴通过轴承旋转穿设在调节轮的中部；驱动电机的输出轴上固定套设有齿轮，齿轮的上侧与齿环相啮合设置；门体的左右两侧壁上对称固定设置有导向条，导向条的左右两侧壁上对称固定设置有棘齿；槽的内部通过轴承旋转设置有二号转轴，二号转轴上固定套设有卡扣，卡扣的另一端与棘齿相卡设；自动化的调节方式，门体启闭更加方便，减少了对地面空间占用，增加了门体的抗破坏能力，同时，有效的防止门体下落，增加了装置整体的安全性能。
