Anti-pry anti-theft instant lock cylinder

Abstract

A kind of anti-prying and anti-theft lock cylinder, which is mainly composed of a lock shell 1, an inner core 2 and a key slot 6, the inner core 2 is installed inside the lock shell 1, reset by a return spring 8, because the return spring 8 is Compression spring, compression spring all has compression limit, utilizes compression limit to control inner core 2 to protrude distance, one end on the lock housing 1 has the corresponding keyhole with inner core 2, and abdication pin 4, abdication spring 5, Working pin 9, working spring 10, jacking pin 12, jacking spring 13, inner core 2 is provided with false opening pin 3, key slot 6, moving pin 7, clutch pin 11 and forms.

Description

technical field [0001] The invention relates to a lock cylinder, in particular to an anti-picking and anti-theft instant lock cylinder. Background technique [0002] At present, well-known lock cylinders are all rotary, mainly made up of lock casing, inner core and key, need turn key to drive inner core rotation with hand during opening, inner core drives dead bolt again and opens lockset. Moreover, the lock cylinders are exposed and installed, and the keyholes are more than 2 mm wide. Thieves can easily open them with technology, or forcibly rotate the lock cylinder, or use a drill to destroy the lock cylinder, and the exposed lock cylinder is also easy to corrode, which reduces the quality of the lock. service life etc. Since the dead bolts are telescopic, controlling the telescopic dead bolts with a rotary lock cylinder requires additional conversion workpieces, which increases the cost and the failure rate. Contents of the invention [0003] In order to overcome the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem that existing lock cylinders are all rotated by keys, the present invention provides a kind of anti-prying and anti-theft lock cylinder that can be opened immediately. The inner core 2 is installed inside the lock case 1 and is reset by the return spring 8. Since the return spring 8 is a compression spring, the compression spring has a compression limit, and the extension distance of the inner core 2 is controlled by the compression limit. One end of the lock case 1 has a The key hole corresponding to the inner core 2 is composed of the abdication pin 4, the abdication spring 5, the working pin 9, the working spring 10, the top force pin 12, and the top force spring 13. The inner core 2 is provided with a mis-open pin 3 , key slot 6, moving marbles 7, clutch marbles 11
