Description

Technical Field

[0001] The invention belongs to the technical field of locks, and in particular relates to a mechanical and electronic integrated emergency double-control lock. Background Art

[0002] The new standard of GB10409 anti-theft safes (boxes) was announced in April 2019 and implemented on May 1, 2020. The existing locks configured on anti-theft safes (boxes) generally use a main control lock and an electronic lock (a solenoid valve). In order to ensure that the electronic lock can still be opened when the power is off or fails, an emergency opening lock is also configured. Its safety requirements have obviously lagged behind the indicators of the new standard, so a dual-control lock with high safety performance suitable for the new standard is designed. The present invention subverts the design concept of conventional locks, integrating convenient electronic identification opening and closing with mechanical emergency opening and closing, making up for the safety defects of current anti-theft safes (boxes), gun cabinet locks and other locks.

[0003] For example, patent "CN2908703" discloses an electronic safe lock structure: a locking mechanism of an electronic safe consisting of a motor, an eccentric wheel, a pulley, a normally closed travel switch and a normally open travel switch is arranged on a support plate, the output shaft of the motor is connected to the deflection wheel, the eccentric wheel shaft of the eccentric wheel is slidably connected to the slide groove of the slide plate, a lock tongue is connected to the front end of the slide plate, and the normally closed travel switch and the normally open travel switch are arranged between the travels of the slide plate. In this scheme, a locking action signal is given through the main control circuit board, and the motor drives the eccentric wheel to rotate, so that the lock tongue moves to the opening and closing position for opening and closing. When the power is off or the main control circuit board fails to open due to an error, the safe (box) cannot be opened and closed effectively and quickly, and there is no good backup way to open the safe (box). When the safe lock is hit by an external object, the safety lock cannot provide a good protection for the safe. Summary of the invention

After the opening is completed, the first reset connecting pin 5 drives the main lock tongue 2 to reset.

[0033] The electronic actuator 8 is arranged on the lock body 1. The electronic actuator 8 has an electronic module 9 and an actuator motor 10. The electronic module 9 is electrically connected to the actuator motor 10. The actuator motor 10 is in contact with the clutch 3.

[0034] The electronic module 9 is connected to the external identification system 26. When the electronic actuator 8 is activated, the electronic module 9 drives the actuator motor 10 to operate, and the actuator motor 10 cooperates with the clutch 3 and the main lock tongue 2 to open and close.

[0035] A mechanical emergency mechanism 31 is arranged on the lock body 1. The mechanical emergency mechanism 31 has a displacement plate 11 and a blade 12. The displacement plate 11 is arranged on the front side of the blade 12. There are several blades 12, and the several blades 12 are connected one by one. A connecting locking block 13 is installed on the rear side of the blade 12. The connecting locking block 13 is rotatably connected to the auxiliary lock tongue 4.

[0036] The key is inserted into the shifting plate 11 and the blade 12. The teeth on each blade 12 are different. When the key is rotated, the connecting locking block 13 on the rear side of the blade 12 drives the auxiliary lock tongue 4 to rotate. The auxiliary lock tongue 4 cooperates with the clutch 3 to open and close with the main lock tongue 2.
