Laminated lock cylinder

Abstract

Disclosed is a laminated lock cylinder, characterized in that the laminated lock cylinder comprises a lock cylinder sleeve (10), a plurality of laminations (30) and a plurality of sheet-shaped pins (20), wherein pin grooves (11) are symmetrically formed on an inner wall of the lock cylinder sleeve (10), the plurality of laminations (30) which are laminated in sequence and fixed as a whole are arranged in the lock cylinder sleeve (10) in an axial direction, and each lamination (30) is composed of two arch-shaped half laminations (31); the pins (20) are arranged between the two arch-shaped half laminations (31) respectively and are movable in the pin grooves (11) of the lock cylinder sleeve (10), and key holes (21) allowing a key to be inserted and protrusions (22) forming an unlocking password are arranged on the pins (20); after the plurality of laminations (30) and the pins (20) are superposed, the key holes (21) are aligned to form a lock hole, and when no key exists or the key which is not matched with the protrusions (22) is inserted into the lock holes, one end of the pins (20) are located in the pin grooves (11) to clamp the lock cylinder sleeve (10), such that the laminated lock cylinder cannot rotate; when the key matched with the protrusions (22) is inserted into the lock hole, the pins (20) are driven by the key to move in a radial direction, so that the pins (20) and the laminations (30) form a rotatable cylinder, and unlocking can be achieved by rotation.

Description

【Technical field】 [0001] The invention relates to a lock cylinder, in particular to a laminated lock cylinder with convenient processing and assembly and improved safety performance. 【Background technique】 [0002] The lock cylinder is the core component of the lock, which is used to match the key to form the unlock code, so as to realize locking or unlocking. The traditional lock cylinders are pin lock cylinders controlled by springs, which are mainly composed of lower pins, flat pins (also known as upper pins), springs, lock shells and inner tanks. The processing and assembly of this type of lock cylinder is relatively complicated. It needs to separately process the pinholes on each liner and lock case, and must use various equipment such as lathes, drilling machines, and punching machines for processing. Therefore, the processing procedures are complicated and the processing time is long. , Processing and assembly efficiency is low. In addition, the number of pins in th...

Problems solved by technology

The processing and assembly of this type of lock cylinder is relatively complicated. It needs to separately process the pinholes on each liner and lock case, and must use various equipment such as lathes, drilling machines, and punching machines for processing. Therefore, the processing procedures are complicated and the processing time is long. , low processing and assembly efficiency

In addition, the number of pins in the traditional spring pin lock cylinder is limited. Therefore, the complexity of the unlocking code formed by the combination of different pins is also limited, and it is easy to be cracked. Thieves can easily carry out prying or violent demolition according to the working principle of the spring pins.

Therefore, the existing spring pin lock cylinder is not only inconvenient to process, but also needs to be improved in safety.
