Description

Automatic lock body
Technical Field
The invention relates to the field of lock bodies, in particular to an automatic lock body.
Background
A combination lock is a type of door lock that has a high degree of security by virtue of intelligence and automation. The lock tongue of the coded lock generally comprises a inclined tongue and a main tongue, wherein the inclined tongue is convenient for the quick closing of the door body, and the main tongue acts in linkage with the inclined tongue so as to quickly extend out after the door body is closed, so that the door body is further locked. The existing lock body realizes linkage between the main tongue and the inclined tongue in two modes of electric control and manual control, and is specific: when the door is closed in a manual control mode, the inclined tongue is contracted into the lock body due to pressure, and the main tongue is pulled out by lifting the door lock handle, so that the effect of locking the door is achieved. In this way, automatic door locking cannot be achieved, and the main tongue needs to be lifted out of the lock body by manpower. The user easily forgets to lift the handle in the use process, so that the door body cannot be completely locked. The electric control mode is as follows: the oblique tongue is contracted towards the inside of the lock body due to pressure, after the door body is closed, the main tongue is pushed out of the lock body by the control motor after the door body is sensed to be closed by the magnetic induction probe on the lock body. In this way, the lock is susceptible to external environments (such as humidity, dryness, high temperature, low temperature, magnetic field, etc.), and thus the security performance of the lock is unstable, and faults such as short circuit or circuit break are easy to occur after long-term use, i.e. the service life is low. It is therefore necessary to design a lock that automatically ejects the main tongue when the door is closed.
