Electromechanical double-control coded lock without key

Abstract

The invention discloses an electromechanical double-control coded lock without a key, and belongs to the field of locks. The electromechanical double-control coded lock comprises a spring bolt, a box, a shifting fork device, a shifting device and a clutch device. The spring bolt is mainly composed of an oblique tongue assembly and a square tongue assembly. The shifting fork device is arranged in the box and mainly composed of a gear shifting piece, an upper poker, a middle poker and a lower poker, the shifting device is engaged with the gear shifting piece of the shifting fork device and drives the square tongue assembly to get in and out of the box, the clutch device controls the middle poker and the upper poker or the lower poker of the shifting fork device to synchronize or separate, comprises a clutch piece and is controlled by a motor controller. The electromechanical double-control coded lock further comprises a mechanical code device independently controlling the action of the clutch device and provided with a coded disc with changeable codes. According to the electromechanical double-control coded lock, unlocking is achieved through independent control of the motor clutch and the mechanical code device, and mutual influences are avoided; and meanwhile, the codes of the mechanical code device can be changed, and safety of users is ensured.

Description

technical field [0001] The invention relates to the field of locks, in particular to an electromechanical dual-control mechanical combination lock. Background technique [0002] For a long time, people try hard to manufacture a kind of lockset that can supply antitheft safe door and other occasions to use, easy to operate, safe and reliable, to replace the mechanical antitheft lock that uses key to open.
