Dormant lock mechanism for controlling closing lock in civil defence door and mounting method of dormant lock mechanism

Abstract

Disclosed are a dormant lock mechanism for controlling a closing lock in a civil defence door and a mounting method of the dormant lock mechanism. The dormant lock mechanism comprises a sheath and a shaft sleeve which are disposed in a door leaf; the section of a cavity in the shaft sleeve is round; the end of the right side of the sheath is connected to the outside of the end of the left side of the shaft sleeve in a sleeving mode; a dormant lock shaft and a closing lock shaft are arranged in a communicating cavity in sequence from left to right, and the communicating cavity is formed through sleeved connection of the sheath and the shaft sleeve; a rotary knob is disposed outside the dormant lock shaft and inside the sheath; the end of the left side of the rotary knob is exposed out of the sheath, the end of the right side of the rotary knob and the dormant lock shaft are in sleeved connection and fixed, and the exposed portion of the rotary knob is connected with a handle; the dormant lock shaft comprises a lock core fixing end and a closing lock shaft connecting end; and a combinator is disposed in the dormant lock shaft, and the external diameter of the combinator is matched with the internal diameter of the dormant lock shaft. The dormant lock mechanism for controlling the closing lock in the civil defence door and the mounting method of the dormant lock mechanism have the characteristics of being safe, practical and the like, are excellent in popularization and practical values and can produce good economic benefits after being widely applied and popularized.

Description

technical field [0001] The invention relates to the technical field of lock installation, in particular to a built-in lock mechanism for controlling the lock inside a civil air defense door and an installation method thereof. 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 restrict irrel...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a built-in lock mechanism and installation method for controlling the internal locking of civil air defense doors, to solve the technical problem that the existing locking reliability is low, and other personnel cannot be completely restricted from opening the locking; There are technical problems that the technical application range is narrow and cannot be adapted to various civil air defense doors
