The invention has the advantages that when the lock is unlocked, the square bolt and the inclined bolt can be driven to move in one step, the unlocking is fast and reliable.

Description

technical field [0001] The invention belongs to the technical field of lock manufacturing, and specifically refers to a mortice lock with a fingerprint identification function. Background technique [0002] The mortise lock is a relatively common door lock. As the Chinese patent application number is 200710154455.9, the invention patent application discloses a mortise lock structure, including a lock body, a square tongue, an oblique tongue and a transmission mechanism, etc., but the defects of its existence are : Need to turn the key many times to make the square tongue and the oblique bolt all withdraw in the lock body, and its mechanical structure is complicated. [0003] In recent years, there have been fingerprint recognition mortise locks that combine fingerprint recognition technology with traditional mortise locks. Existing fingerprint mortise locks generally include a fingerprint collection window, a lock body with a deadbolt and a deadbolt transmission mechanism, ...

[0002] The mortise lock is a relatively common door lock. As the Chinese patent application number is 200710154455.9, the invention patent application discloses a mortise lock structure, which includes a lock body, a square tongue, an oblique tongue and a transmission mechanism, etc., but its existing defects are : It is necessary to turn the key many times to make the square tongue and the oblique tongue retract into the lock body, and its mechanical structure is complex

Although the current fingerprint recognition mortise lock has its advantages, it has the following disadvantages: multiple operations are required to realize the opening and closing of the lock. Fingerprint recognition of the movement of the mortise lock; in addition, there is no signal prompt whether the deadbolt is accurate, for example, the deadbolt is not fully ejected (that is, it is inserted into the corresponding position of the door frame) and it is locked, resulting in a false lock; in addition, the current structure of the fingerprint recognition mortise lock more complicated
