Mechanical and electronic composite lock

Abstract

A mechanical and electronic composite lock comprises a lock case and an electromagnetic valve lock with an electromagnet core. The electromagnet core is sleeved with a spring and fixed with a retainer ring. The mechanical and electronic composite lock is characterized in that the inside of the lock case is rotatably connected with a lock bolt plate via a rotating shaft, and the rotating shaft is sleeved with a first torsional spring; an electromagnet which is arranged transversely is further disposed in the lock case via a base, the middle of a crow plate is connected to the upper side of the base, the crow plate can deflect left and right, and the upper end of the crow plate is connected with the right of the base via a tension spring; and when the lock bolt plate extends out of the lock case, the upper end of the lock bolt plate matches with a gear position of the electromagnet core extending outwards so as to stop the lock bolt plate from rotating to retract into the lock case, and the lower end of the crow plate matches with the retainer ring in a retaining manner so as to stop the electromagnet core from moving upwards. The electromagnet and the crow plate are further disposed in the lock case, when the electromagnet is in power failure, the crow plate can stop the retainer ring from moving upwards and has an auxiliary locking effect, locking ability of the composite lock is greatly strengthened, and safety of the composite lock is enhanced.

Description

technical field [0001] The invention relates to a lock structure for a safe, in particular to a mechanical-electronic composite lock. Background technique [0002] The mechanical-electronic composite lock on the traditional electronic safe includes a sliding plate on the back of the door panel. The front end of the sliding plate is connected with a bolt head. The sliding plate is driven by a driving structure and can slide forward and backward. Lock, the electromagnet core can be retracted out of the solenoid valve lock and cooperate with the slide plate to prevent the slide plate from moving forward and backward. The driving structure generally includes a handle, a turntable or a paddle set on the back of the door panel, and the turntable or paddle is connected with the slide plate and rotates. The handle can drive the slide plate to move back and forth under the drive of the turntable or the paddle. [0003] For example, a Chinese utility model patent No. ZL02215701.8 (an...

AI Technical Summary

Problems solved by technology

[0004] The existing mechanical and electronic composite locks have the following disadvantages: 1. The electromagnet core is in direct contact with the skateboard. Once the handle is turned too hard, the skateboard will directly hit the electromagnet core, damage the electromagnet core or directly slide over the electromagnet core , so that the door is opened, causing potential safety hazards; 2. It is easy to be opened by vibration. The existing electromagnetic valve lock is held in the working position because its electromagnetic core is stretched out through a spring (generally the elastic force is small, and it cannot be sucked up if it is too large). The box body, that is, lift one side of the box body, put one hand on the handle position, and control the drop of the box body with the other hand, and turn the handle at the moment of landing. There is a downward force in the relationship, and it will go down a short distance, thus leaving the working position, causing a safety hazard; 3. The existing mechanical and electronic composite lock has no emergency opening function, and it is not easy to open after the electromagnetic valve lock is damaged.
