Separating-connecting type safety anti-theft lock

Abstract

The invention relates to the technical field of anti-theft locks, in particular to a separating-connecting type safety anti-theft lock. According to the separating-connecting type safety anti-theft lock, a lock body is internally provided with a lock tongue shifting block and a knob shaft for driving the lock tongue shifting block to rotate; the lock body comprises a shaft coupling device for shaft coupling of the knob shaft and a lock cylinder, the shaft coupling device comprises a motor located on the right side of the knob shaft, and a knob shaft connector which is in threaded connection with the knob shaft is arranged at the tail part of the stretching-out end of a rotating shaft of the motor in a sleeving mode; an open groove is formed in the outer wall of an opening of the left end of the knob shaft, and a protrusion for being conveniently clamped into the open groove is arranged on the outer wall of the knob shaft connector; and a lock cylinder connector which conveniently enables the lock cylinder and the knob shaft to conduct shaft coupling rotation is arranged on the right side of the lock cylinder, and the lock cylinder connector is connected with the right end of the lock cylinder through a spring. By adopting the technical scheme, the separating-connecting type safety anti-theft lock is novel in structure and reasonable in design, through the mode that the motor isarranged in a lock handle and a control signal generating circuit is arranged in a key, the effect that unlocking is conducted through the specific key is achieved, and security anti-theft performance of the lock is enhanced.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a clutch type safety anti-theft lock. Background technique [0002] Lockset has been developed so far and has become an indispensable security and confidentiality article in people's daily life and work. With the development of science and technology, all kinds of anti-theft safety locks have gradually replaced traditional mechanical locks and entered every household, providing security for people's daily life and work. [0003] Traditional locks only need a key with matching teeth to open the lock. What's more, only a simple hook tool can simulate the teeth of the key to open the lock, which seriously threatens the property safety of users. The basic structure of the anti-theft locks currently on the market does not depart from the design framework of traditional mechanical locks. With the spread of unlocking tools and technologies in the Internet age, this type of anti-theft loc...
