The invention relates to the technical field of civil air defense doors, and discloses a movable threshold type civil air defense door convenient to disassemble and assemble, which comprises a concrete mechanism, an opening and closing mechanism is arranged on the upper side of the concrete mechanism, the opening and closing mechanism comprises a civil air defense door frame and a civil air defense door body, and rotary opening and closing valves are arranged on the front side and the rear side of the civil air defense door body. A positioning clamping groove hole is formed in one side of the civil air defense door body, and a supporting positioning rod is arranged in the middle of the positioning clamping groove hole. When an electric hydraulic cylinder is opened, the electric hydraulic cylinder can drive a connecting handle to move upwards, the connecting handle moves upwards to enable a rotary connecting rod, a connecting supporting strip and a movable threshold body to move upwards at the same time, and when power failure occurs, the connecting handle is rotated, so that the connecting handle drives the rotary connecting rod to rotate around a limiting clamping ring; the connecting handle is rotated to the upper side of the hydraulic jack, and the connecting handle can be manually lifted or lowered through the hydraulic jack, so that the movable threshold body moves upwards.
Description
technical field [0001] The invention relates to the technical field of air defense doors, in particular to a living threshold type air defense door with convenient disassembly and assembly. Background technique [0002] The civil air defense door is the door of the entrance and exit of the people's protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double-leaf protective airtight doors and airtight doors, and single and double-leaf protective airtight doors and airtight doors. Civil defense, civil defense is an international word, English CIVIL DEFENCE, is the government's mobilization and organization of the masses, take anti-aircraft, disaster relief measures, implement rescue operations, prevent and reduce disaster hazards. Civil defense doors are civil defense protective equipment. The characteristics of the civil air defense door live threshold are that the threshold is not installed at ordinary times...
