Abstract

A two-way built-in lock mechanism for controlling internal locking of civil air defense doors and its installation method, comprising a shaft sleeve installed in the door leaf and sheaths symmetrically installed at the ends of both sides of the shaft sleeve, the inner cavity of the shaft sleeve has a circular section A built-in lock shaft assembly is provided in the connected cavity formed after the sheath and the shaft sleeve are sleeved, and the left and right sides of the built-in lock shaft assembly and the outside of the shaft sleeve are symmetrically provided with knobs and sheaths; the built-in lock shaft assembly includes a built-in lock The shaft and the locking shaft cap connected with the bolts of the built-in lock shaft, the built-in lock shaft includes the fixed end of the lock cylinder and the shaft rod, and two joints are arranged symmetrically inside the shaft rod, and the lock core is arranged in the fixed end of the lock cylinder and the locking shaft cap, and the key is inserted After the knob and the lock core enter the key socket on the combination, the key rotates and pushes forward to drive the combination to rotate and move forward. The invention has the characteristics of safety and applicability, has good popularization and practical value, and can produce good economic benefits after being widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of lock installation, in particular to a bidirectional built-in lock mechanism and an installation method for controlling the inner lock of a civil air defense door. Background technique [0002] At present, civil air defense doors have been installed in a large number of entrances and passages in places such as civil air defense material warehouses, airport underground parking lots, railway stations, and large underground commercial centers. In addition to the protective and sealing functions of civil air defense doors, the above places usually have to restrict the opening and closing of unrelated personnel. Operation, that is, manages door functions. [0003] Existing civil air defense doors can be divided into manual doors and electric control doors according to the control type of door leaf opening and closing. Among them, the electric control door has an access control device, which can directly restri...
