Magnetic control type lock cylinder

Abstract

The invention discloses a magnetic control type lock cylinder which comprises a lock shell. A lock container hole is formed in the lock shell, a lock container is rotationally arranged in the lock container hole, a key hole allowing a key to be inserted therein is formed in the lock container in the axial direction, and a plurality of side bead holes communicated with the key hole are formed in the lock container in the radial direction. Side beads with one ends capable of being inserted into the key hole and matched with teeth of a key are arranged in the side bead holes in a sliding mode, aclamping groove is formed in the side wall of the lock container hole, first springs driving the other ends of the side beads to be clamped into the clamping groove when the lock cylinder is in a locked state are arranged in the side bead holes, and magnetic beads are embedded into the key. The magnetic force of attraction of the magnetic beads to the side beads is larger than elastic force of thefirst springs. When the key is inserted for unlocking, the key drives the side beads to be matched with teeth of the key through the magnetic force of the magnetic beads, so that the other ends of the side beads are disengaged from the clamping groove, and then the lock container can rotate for unlocking. The lock cylinder is higher in safety coefficient, and can effectively prevent technical unlocking conducted by lawbreakers.

Description

【Technical field】 [0001] The invention relates to the technical field of locks, in particular to a magnetically controlled lock cylinder. 【Background technique】 [0002] Generally, the existing lock cylinder is provided with a front pinball set and a side pinball set. When the correct key is inserted, the correct key pushes the front pinball set and the side pinball set to the unlocking position through the teeth, and then passes The key drives the lock barrel to rotate to complete the unlocking, but for this kind of lock cylinder, criminals can easily open it technically by provoking, so the safety factor of this kind of lock cylinder is not conducive to protecting the property safety of users. 【Content of invention】 [0003] In order to solve the above problems, the present invention provides a magnetically controlled lock cylinder with a high safety factor and can effectively prevent technical opening. [0004] In order to achieve the above object, the present inventio...
