Description

Technical Field

[0001] The utility model belongs to the technical field of locks and relates to an embedded electromechanical lock body. Background Art

[0002] Traditional locks generally have a main bolt and a slant bolt on the lock body. When opening the door, first insert the key into the lock core, and then rotate the lock core to drive the main bolt and the slant bolt to move horizontally to unlock the door. When unlocking the door, the lock core rotates and drives the main bolt to move horizontally. After the main bolt returns to the lock body, it drives the slant bolt to move horizontally back into the lock body. Therefore, when unlocking the door, you need to turn the key several times continuously to complete the unlocking. It is impossible to achieve synchronous movement of the main bolt and the slant bolt, and the unlocking time is long.

[0003] The electronic unlocking part in the lock body is realized by a motor arranged in the lock body to realize the unlocking function. The motor is connected to the internal structure of the lock body through multiple gear sets to realize the unlocking function. When the gear set contacts the internal structure of the lock body and the motor is damaged during the unlocking process, the motor, the gear set and the internal structure of the lock body form a whole. The damaged motor locks the whole, and the door lock cannot be opened by an external key or an internal handle, which is inconvenient to use. Utility Model Content
