Locking tongue mechanism and intelligent security door lock

Abstract

The invention discloses a locking tongue mechanism, which includes a locking tongue shell and a locking tongue. The locking tongue mechanism further includes a locking tongue driving mechanism drivingthe locking tongue to move forward and backward, the locking tongue mechanism further includes guiding parts, the locking tongue driving mechanism includes a locking tongue driving part, a locking tongue connecting part and a reset mechanism, wherein the lock tongue driving part is used for being driven by a lock bolt mechanism to move backward during backward movement of the lock bolt mechanism,and the locking tongue driving part is connected with the guiding part, moves up and down relative to the guiding part and the locking tongue shell, and meanwhile, moves forward and backward relativeto the guiding part and the locking tongue shell; the lock tongue connecting part is movably connected with the lock tongue driving part and can move up and down relative to the shell under driving of up and down movement of the lock tongue driving part, and the lock tongue connecting part is fixedly connected with a lock tongue; and the reset mechanism drives the locking tongue driving part to reset and drives the locking tongue to reset. The invention further discloses an intelligent security door lock with the locking tongue mechanism. The intelligent security door lock can be used for intelligent security doors.

Description

【Technical field】 [0001] The application relates to a lock, in particular to a bolt mechanism and an intelligent anti-theft door lock. 【Background technique】 [0002] Existing intelligent anti-theft door locks usually include an unlock controller, a latch mechanism, and a latch drive mechanism. Motion unlock. Some anti-theft door locks are also provided with a dead bolt connected with the door handle, which drives the dead bolt to open and close by turning the door handle. However, the deadbolt of the existing intelligent anti-theft door lock is driven by the door handle, and there is no linkage between the deadbolt and the deadbolt mechanism. Usually in the unlocked state, the deadbolt mechanism shrinks, and the door is mainly kept closed by the deadbolt. The door can be easily opened by turning the door handle, which poses a safety hazard. 【Content of invention】 [0003] In order to solve the technical problems of the prior art that the intelligent anti-theft door loc...
