Along with the rapid development of intelligence fingerprint trick lock trade, the safety guarantee of intelligence fingerprint trick lock, the perception of intelligence fingerprint trick lock to the door state and the life of intelligence fingerprint trick lock also more and more obtain people's attention, and these indexes have important influence to the use of intelligence fingerprint trick lock simultaneously.
A general intelligent fingerprint coded lock usually drives an oblique tongue component and a square tongue component to extend or contract by a connecting rod mechanism, and the rear end of an oblique tongue rod of the oblique tongue component is blocked by a stop block from moving backwards. And the general intelligent fingerprint coded lock independently guarantees the safety of users in the room by arranging the safety tongue component. Through the arrangement of the dead bolt microswitch, when the dead bolt extends out or retracts, the dead bolt can contact or separate the microswitch, so that the door state can be sensed.
The prior art has the following defects: 1. the connecting rod mechanism is inaccurate in movement, the stress of parts inside the mechanism is large, and when the connecting rod mechanism drives the latch bolt assembly to extend out or contract and is blocked by the blocking block, a rod piece in the latch bolt assembly is easily deformed under stress, so that the service life of the intelligent fingerprint coded lock is influenced. 2. The safety bolt assembly is weaker than the square bolt assembly, and the safety factor of locking the door by only depending on the safety bolt assembly after the square bolt assembly is retracted is lower. 3. Only the dead bolt micro switch is arranged, the inaccurate opening or closing state of the door is sensed by sensing the extension or contraction of the dead bolt, and when the door is in the opening state, the state of the door cannot be accurately judged by the extension or retraction of the dead bolt.
