Clutch type lock and keys

Abstract

The invention discloses a clutch type clock and keys. The lock comprises a clutch type lock cylinder, a transmission mechanism and a lock sleeve, the keys are matched with the lock cylinder, the transmission mechanism comprises an inner sleeve, a lifting pin, a limiting pin and a clutch pin, the lock cylinder rotates to form a clutch through groove, the lower portion of the clutch pin enters the clutch through groove after the clutch pin is pressed by the lifting pin, the upper portion of the clutch pin is located in a strip-shaped hole of the clutch pin of the inner sleeve, and unlocking is achieved through linkage of the lock cylinder and the inner sleeve; when the lock cylinder rotates reversely to be locked, the limiting pin limits the inner sleeve to rotate continuously, the lock cylinder continuously rotates reversely to make the lower portion of the clutch pin pressed into the strip-shaped hole of the clutch pin, the upper portion of the clutch pin enters a groove of the lock sleeve, and linkage of the lock cylinder and the inner sleeve is removed. According to the clutch type clock and the keys, the lock cylinder is further improved, and the lock cylinder comprises the multiple coding plates. The clutch type clock and the keys have the advantages that the structure is simple, the transmission is stable when the lock is unlocked or locked, the coding information content of the lock cylinder is large, and the capacity of controlling technical opening is strong.

Description

technical field [0001] The invention relates to a clutch type lock head and a key matched with the lock head. Background technique [0002] Anti-theft door locks are a daily necessity. Existing anti-theft locks generally include lock operating systems, lock cylinders, and transmission mechanisms. There have been many developments and their safety performance has been greatly improved. However, in terms of structural design and stability There are still deficiencies; the lock cylinder is the most critical part of the lock, which determines the anti-theft performance of the lock head. At present, there are pin locks commonly used in daily life. , has a very high security performance against technical opening. The invention of the clutch lock head greatly improves the ability to prevent non-technical opening, especially improves the ability to prevent rotation torque damage. Although some clutch-type lock heads and pin lock cylinders disclosed at present can solve the basic a...

AI Technical Summary

Problems solved by technology

Although some clutch-type lock heads and pin lock cylinders disclosed at present can solve the basic anti-theft function, the mutual opening rate of keys is high, the key quantity of the lock cylinder is small, and the structure of the lock cylinder is complicated, and the processing is difficult. Therefore, it is necessary to design a lock with strong anti-technical opening ability and large amount of encoded information.
