Mechanical lock cylinder and lock

Abstract

The invention provides a mechanical lock cylinder and a lock, and belongs to the technical field of locks. The mechanical lock cylinder comprises a lock shell, a lock liner, a locking mechanism and multiple blades. The lock liner is rotatably arranged on the lock shell, and a lock hole is formed in the lock liner. The locking mechanism has a locking state for preventing the lock liner from rotating and an unlocking state for allowing the lock liner to rotate. Each blade is movably arranged on the lock liner in the first preset direction and the second preset direction, and each blade has a first position, a second position and a third position. When at least one blade is located at the first position or the second position, the locking mechanism is in the locking state, and in the process that a key is inserted into the lock hole, the key can push all the blades to move from the first positions to the second positions in the first preset direction and push all the blades to move from the second positions to the third positions in the second preset direction, so that the locking mechanism is switched from the locking state to the unlocking state. The mechanical lock cylinder of the structure is high in secret key quantity and technical opening prevention capacity and not prone to being illegally prized open.

Description

technical field [0001] The present application relates to the technical field of locks, in particular, to a mechanical lock cylinder and a lock. Background technique [0002] With the vigorous development of society and economy, in order to ensure people's property safety, people's anti-theft requirements for lock cylinders are also getting higher and higher. Existing mechanical lock cylinders usually use pins, blades or magnetic structures to lock or unlock the lock cylinder. The pin lock core cooperates with the pits of different heights on the key to push the pin to move to realize the opening and closing lock; the blade lock core cooperates with the tooth flower groove on the key to push the blade to move in the lock cylinder to realize the opening and closing lock; The steel generates magnetic force, which pushes the locking piece to move to realize opening and closing. But the locking mode of the mechanical lock core of this structure at present has been known by the...
