Threshold-free civil air defense door and production process thereof
The invention provides a threshold-free civil air defense door and a production process thereof, and relates to the technical field of civil air defense doors, the threshold-free civil air defense door comprises a door frame and a door body, a first linkage arm is hinged to the rear side of the top in the door frame, and a second linkage arm is hinged to the front side of the top in the door frame; one end of the first linkage arm and one end of the second linkage arm are hinged to one end of the top of the door body, a gear is rotationally arranged at one end of the top in the door frame, and a driving arm is arranged at the bottom of the gear; the hinge structure of the first linkage arm and the second linkage arm is adopted for connecting the door body and the door frame, the rack is pushed to move through the electric telescopic rod, so that the gear rotates, the driving arm is driven to swing, and the driving arm is hinged to the door body, drives the door body to move and is matched with linkage of the first linkage arm and the second linkage arm; the door body can move into the door frame or move out of the door frame, opening and closing of the door body do not need rotation of the door body, the phenomenon that the door body automatically rotates and even resets cannot occur, and using is more reliable.
本发明提供了一种无门槛人防门及其生产工艺，涉及人防门技术领域，包括门框和门体，所述门框内部顶部的后侧铰接有第一联动臂，且门框内部顶部的前侧铰接有第二联动臂，所述第一联动臂和第二联动臂的一端均与所述门体的顶部的一端铰接，所述门框内部顶部的一端转动设有齿轮，且齿轮的底部设有驱动臂；本发明采用第一联动臂、第二联动臂的铰接结构，来连接门体和门框，通过电动伸缩杆推动齿条移动，使得齿轮旋转，带动驱动臂摆动，由于驱动臂与门体铰接，带动门体移动，配合第一联动臂、第二联动臂的联动，使得门体可以移动至门框内或移动而出，门体的开合不需要门体自身的旋转，门体不会出现自动转动甚至复位的现象，使用更加可靠。
