Description

Technical Field

[0001] The invention relates to the technical field of electronic locks, in particular to an electronic lock body. Background Art

[0002] The lock body is an important part of the lock, and the quality of a lock is directly related to the safety of the lock. At present, there are many electronic locks on the market, some of which are expensive and some of which pose safety risks. The structure of some electronic locks is unreliable, and some lock bodies can be unlocked when the handle is rotated more than 90 degrees, resulting in certain safety risks in the locks; some electronic lock bodies are troublesome to change direction, requiring professionals or replacement of parts to achieve the change of direction, and some even need to confirm the opening direction of the lock at the factory, that is, to customize more than two sets of parts for the lock body, and adapt the relevant parts according to whether the door opens to the left or right at the factory. This not only increases the cost of the lock body, but also adds a lot of trouble when renovating old doors, and also increases the error rate. In addition, most of the lock body clutches on the market currently do not achieve front and rear separation, so lifting the front handle will drive the rear handle to lift, which poses a greater safety risk.

[0076] like Figures 1 to 23As shown, the oblique tongue push piece 91 is provided with a driving portion 911 on the side close to the lock head 92. When the lock head 92 rotates in the other direction, the driving portion 921 of the lock head 92 slides into the opening groove 32 and drives the main lock tongue fork 30 to rotate in the other direction. After that, the driving portion 921 of the lock head 92 disengages from the opening groove 32, and the driving portion 921 of the lock head 92 drives the oblique tongue push piece 91 to slide along the fourth sliding groove 94 and the fifth sliding groove 95 through the driving portion 911.
