Abstract

Provided is an anti-breaking lock cylinder. A spring capable of pushing an inward turning key towards a driving lever is arranged in an inner lock liner. A platform is arranged on the upper portion of the inward turning key through lathe turning. A lower magnetic piece is arranged on the platform of the inward turning key, an upper magnetic piece is arranged in an upper magnetic piece sliding groove of the inner lock liner, and the lower magnetic piece and the upper magnetic piece can be attracted mutually. In a normal state, the bottom of the upper magnetic piece is tangent to the outer circle of the inward turning key so that the effect that a door is locked or unlocked by rotating the inner lock liner after a correct key is inserted cannot be affected. When the lock cylinder breaks down at the groove, the spring pushes the inward turning key by a very small distance, then the lower magnetic piece attracts the upper magnetic piece to fall into the platform under the action of magnetic force so that the inward turning key can be clamped in the inner lock liner, and through cooperation of the inward turning key and a first marble assembly, a dual effect is achieved to prevent the door from being violently unlocked by illegal people, so that the anti-breaking lock cylinder has higher antitheft performance and more safe in use. Besides, when the outer half part of the lock cylinder is violently broken by somebody, an owner in a room can still unlock the door by inserting the key in the inner lock liner, and therefore the anti-breaking lock cylinder is simpler and more reasonable in structure.
