Abstract

The invention relates to a pin tumbler lock plug. The pin tumbler lock plug comprises a lock plug base body and a pin assembly, wherein an unlocking rotating body is arranged on the lock plug base body in a rotating mode, one end, relative to the rotating axis, of the unlocking rotating body is a key matching end matched with a key and rotated under the driving of the key, the other end of the unlocking rotating body is a linkage end for switching an object between an unlocking state and a locking state in the rotating process, key inserting openings for allowing the key to be inserted are correspondingly formed in the lock plug base body and the key matching end of the unlocking rotating body, a pin seat body is arranged in the lock plug base body, at least two pin grooves are formed in the pin seat body in the rotation direction of the unlocking rotation body, pin holes are formed corresponding to the pin grooves in the unlocking rotating body, pin movable cavities for installing pinassemblies are formed by the corresponding pin grooves and the pin holes, and each pin assembly comprises two pins which are arranged in sequence and a reset piece which resets the pins towards the key matching end of the unlocking rotating body. By adopting the scheme, the pin tumbler lock plug has the advantage that the safety performance of the lock plug is improved by changing the arrangementmode of the pins.

Description

technical field [0001] The invention relates to the field of locks, in particular to a novel lock cylinder, which can be used as door locks, luggage locks, safe locks and the like. Background technique [0002] A lock is a device that is placed on an openable and closable utensil and is opened with a key or a password, and has the function of protecting the items in the utensil. The lock cylinder is the core part of the lock, which determines the anti-theft performance of the lock. [0003] Most of the existing lock cylinders are pin lock cylinders. The principle is to use multiple cylindrical parts (called lock springs, pins or beads) of different heights to lock the lock cylinder. When the correct key is put in, each lock spring is pushed To the same height, the lock cylinder is released. Since the pins are arranged in a straight line, the bump key can be opened quickly without using the correct key, so the anti-theft performance is relatively poor. Contents of the inve...
