Abstract

The invention relates to an integrated lift translation protective sealing door. Wherein, its hinge leaf is fixed with upper axle base and lower axle base; said two bases are connected to the prolonged hinge leaf axle via bearings; the upper and lower hinge leaf plates are connected to the upper and lower connecting base plates via the upper and lower torque balance translation support bases; one end of upper and lower torque balance translation support bases is connected to the upper and lower connecting base plate pin axles, while the another end sheathes the prolonged hinge leaf axle; there are spaces between the balance translation support bases and the hinge leaf axle base, and between the pin axle holes and the connecting base plate pin axles; the jack lifter is arranged between the upper hinge leaf and the lower hinge leaf, while its square head of lift end is supported inside the supporting translation base; there is space between the square head and the wall of supporting groove; the inner wall of supporting groove has concave rolling channel embedded with rolling balls. The invention can be widely used in protective projects.

Description

(1) Technical field [0001] The invention relates to protective equipment for protective engineering, in particular to a protective airtight door for tunnel entrances and exits in subway civil air defense engineering. (2) Background technology [0002] The protective equipment of the subway civil air defense project has the functions of air defense in wartime and disaster prevention in peacetime. If the needs of civil air defense are taken into account during construction, planning, design, and construction are unified, and key parts and important facilities are well protected, the subway can be used as the main traffic artery of the city in normal times, and it can also become the main road for evacuation of urban civil air defense in wartime. Personnel shelter and material storage. Under the predicted urban secondary disasters during and after the attack of nuclear weapons, chemical weapons, and conventional weapons, the safety of personnel and equipment is guaranteed, and...
