Movable doorsill structure of civil air defense door
The invention provides a movable doorsill structure of a civil air defense door, and relates to the field of protection equipment. The movable doorsill structure of the civil air defense door comprises a protection door, wherein the protection door is hinged to a doorframe, a vertical groove extending downwards is formed in the ground, a doorsill matched with the vertical groove slides in the vertical groove, a cavity is formed in the ground and communicates with the bottom of the vertical groove, a round roller is rotatably connected in the cavity, the round roller is in a transverse cylindrical shape, a horizontal cross rod slides between the round roller and the doorsill, one end of the cross rod is in transmission connection with the doorsill, the other end of the cross rod is in sliding connection with the inside of the round roller, the cross rod horizontally slides to push the doorsill to slide in the vertical groove, the end of a lever is treaded by people to enable the round roller to rotate in the cavity, and the round roller pulls the cross rod to slide in the cavity. The doorsill and a connecting structure thereof can be completely hidden in the ground when not in use,so that the periphery of the protective door is tidy, and normal use is not affected. By treading the lever by people, the doorsill can gradually slide upwards out of the ground, the doorsill can slide out or be retracted through self gravity, assistance of electric energy and other external force is not needed, operation is convenient, and energy is saved.
本发明提供一种人防门的活门槛结构，涉及防护设备领域，包括防护门，防护门铰接在门框上，地面上开设有向下延伸的竖槽，竖槽内滑动有相适配的门槛，地面内开设有空腔与竖槽底部连通，空腔内转动连接有圆辊，圆辊为横放的圆柱形状，圆辊与门槛之间滑动有水平的横杆，横杆一端与门槛传动连接，另一端滑动连接在圆辊内部，横杆水平滑动推动门槛在竖槽内滑动，人为踩压杠杆端部使圆辊在空腔内转动，圆辊拉动横杆在空腔内滑动。门槛及其连接结构在不使用时可完全隐藏在地面内，使防护门周边整洁，不影响正常使用。通过人工踩压杠杆，可使门槛逐渐向上滑出地面，通过自己重力可使门槛滑出或收回，不需要电能及其他外力辅助，操作方便且节能。
