Abstract

The invention provides an anti-error lock cylinder and an unlocking key. The anti-error lock cylinder comprises a lock shell, a first lock liner, a second lock liner and a locking piece; the lock shell is provided with a containing cavity for containing the first lock liner and the second lock liner; the first lock liner and the second lock liner can relatively rotate; the locking piece is locatedin the containing cavity and movably arranged between the first lock liner and the second lock liner; one part of the locking piece can stretch into the first lock liner, and the other part of the locking piece can stretch into the second lock liner; the locking piece is magnetic; when stretching into the first lock liner and the second lock liner simultaneously, the locking piece obstructs relative rotation between the first lock liner and the second lock liner so as to lock the anti-error lock cylinder; and when the locking piece retreats from the first lock liner or the second lock liner under the effect of a magnetic piece of the unlocking key, the first lock liner and the second lock liner can relatively rotate so as to unlock the anti-error lock cylinder. The problem of poor anti-cracking performance of an anti-error locking cylinder in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of industrial safety locks, in particular to an anti-mistake lock cylinder and an unlocking key. Background technique [0002] At present, the keys used in the hierarchical management and control of industrial places such as electric power and coal mines are easy to be copied. As long as the corresponding tooth-shaped grooves are processed, they can be unlocked, and the anti-cracking performance is poor. In addition, with the development of the times, the demand for lock cylinders is increasing. Traditional graded lock cylinders often cannot meet wider and stricter use requirements. Contents of the invention [0003] The main purpose of the present invention is to provide an anti-mistake lock cylinder and an unlocking key to solve the problem of poor anti-cracking performance of the anti-mistake lock cylinder in the prior art. [0004] In order to achieve the above object, according to one aspect of the p...
