A mechanical lock cylinder and a key matched with the mechanical lock cylinder

Abstract

The invention discloses a mechanical lock core and a key matched with the mechanical lock core. The mechanical lock cylinder includes a lock case, a rotary lock cylinder, and a toggle head, and the rotary lock cylinder includes several sequentially arranged circular rotary lock cylinder shells and a rotary lock cylinder arranged between the toggle head and the rotary lock cylinder shell. head. The key includes a mandrel, fixed vanes and handles respectively connected to two ends of the mandrel, and a rotating vane rotatably sheathed on the mandrel. Both the rotary lock cylinder shell and the rotary lock cylinder head of the mechanical lock cylinder of the present invention rotate independently, and are equipped with a key with rotatable blades, so that the angle of unlocking is the angle that each rotary blade on the key can rotate plus each rotation angle. The lock cylinder is rotatable at an angle corresponding to the center of the circle, so other personnel cannot unlock the lock even if they turn and rotate the lock cylinder shell to the corresponding position without a key, which improves the anti-theft effect. And on the basis of the original rotary lock cylinder shell, a tumbler lock password is added, which increases the difficulty of abnormal unlocking and further improves the anti-theft effect.

Description

technical field [0001] The invention belongs to the field of locks, and in particular relates to a mechanical lock core and a key matched with the mechanical lock core. Background technique [0002] At present, most of the mechanical locks on the market rely on the amount of keys and the degree of coupling to achieve the purpose of anti-theft. For example pin lock is to utilize pin to limit the rotation of lock core to realize anti-theft, utilize key to push each pin to a suitable position and release the rotation restriction of lock core to realize unblanking. Suspicious persons utilize the difference in tolerance between pins and pin holes, and use iron wire or special unlocking tools to turn the pins to the appropriate position one by one to unlock the lock cylinder. The anti-theft effect is not ideal enough. The Chinese invention patent with authorized notification number CN202108328U discloses a tumbler lock, the lock body is provided with at least two groups of pin gr...
