Automatic safety protection lock
The invention relates to an automatic safety protection lock which comprises a lock bolt automatic reset mechanism. The lock bolt automatic reset mechanism comprises an idler wheel, a linkage rod, a spring and a shifting plate. The idler wheel is arranged on a side edge, close to a lock tongue, of a base, the front end of the linkage rod is connected with the idler wheel, the back end of the linkage rod is connected with the shifting plate in an abutting mode, the linkage rod is sleeved with a spring, and an oblique face is formed at the lower end of the shifting plate forms. A linkage mechanism of the lock bolt mechanism comprises a push plate, a push face corresponding to the oblique face on the shifting plate is formed at the back end of the push plate, and then linkage resetting of the push plate can be achieved through movement of the shifting plate. According to the automatic safety protection lock, the lock bolt mechanism, a clutch, a key knob drive body, the base and the like are all designed into one module and can be independently installed and replaced, so the automatic safety protection lock is convenient to use.
