specific Embodiment approach 1

[0008] Embodiment 1: A double-layer tumbler lock cylinder is composed of an inner lock cylinder 30, an outer lock cylinder 20, a lock cylinder cover 10, a plurality of pin groups and two positioning pins, and each pin group consists of a first pin 41 , the second pin 42, the third pin 43 and a spring 44, the inner lock cylinder 30 has a key slot 33, and the bottom of the key slot 33 of the inner lock core 30 has a plurality of inner lock pin pinholes 34, and the inner lock core The inner lock core positioning ring groove 31 is set on the outer wall of the 30; the outer lock core 20 has an outer lock core cavity 26 for installing the inner lock core, and the outer lock core 20 is positioned with the inner lock core on the inner lock core 30 outer wall. The inner lock core positioning through hole 22 is arranged on the side wall corresponding to the annular groove 31, and a plurality of inner lock core pin holes 34 corresponding to the bottom of the key groove 33 of the inner loc...

specific Embodiment approach 2

[0012] Specific embodiment two: This embodiment adds an alarm switch device on the basis of a double-layer tumbler lock cylinder described in specific embodiment one. The alarm switch device consists of a probe 51, an insulating pad 52, a conductive Ring 53 and contact probe 54, the bottom surface of the inner lock cylinder 30 in this embodiment has a groove 35 with a width b, the symmetry axis of the groove 35 passes through the central axis of the inner lock cylinder 30, A through hole 24 is formed between the bottom of the outer lock core 20 and the bottom of the outer lock core cavity 26, the distance between the opening edge of the through hole 24 in the outer lock core cavity 26 and the center of the outer lock core 20 is c, so 2c>b, the insulating pad 52 is circular and fixed on the bottom of the outer lock cylinder 20, the conductive ring 53 is fixed on the insulating pad 52, one end of the probe 51 is fixedly connected to the conductive ring 53, and the other end of th...

Abstract

The invention relates to a double-layer spring lock lock-pin, which relates to a lock pin. The invention solves a problem that the anti-theft function of the prior spring lock is bad. The invention changes the prior lock pin to a double-layer structure on the basis of the structure of the prior spring lock lock-pins, an inner and an outer lock pins can relatively be rotated, a key groove is fixed on an inner lock pin, and an outer lock pin is connected with a shifting block for unlocking, the inner lock pin is adopted to drive the outer lock pin to unlock, a cog-wheel on an end socket of one side of the key groove which is close to a marble which is arranged between the inner lock pin and the outer lock pin is bigger than an cog-wheel on the other end. The lock pin of the invention can also add a warning switch device, the warning switch is actuated when the inner lock pin is separately rotated and the outer lock pin is not rotated. The double-layer spring lock lock-pin of the invention can be applied in all the prior spring lock locksets, which can be connected with the prior warning devices.

Description

technical field [0001] The invention relates to a lock cylinder. Background technique [0002] Lock is one of the commonly used tools for anti-theft. There are many types of locks, and the pin lock is one of the most commonly used locks. Most of the existing pin locks are single-layer lock cylinders. Most of the lock cores of this structure reduce the unlocking rate of the master key by increasing the number of bullet groups. Existing anti-theft system is also various, and the quality of lockset and anti-theft door is superior, and destructive unblanking is difficult to open, and technical unblanking is easy to handle, and this technology is easy to grasp, just can grasp from the Internet and books. Existing a lot of thieves have mastered this technology, and the incidence rate of burglary cases of technical unlocking in various places increases year by year, so guarding against technical unlocking is an effective means to improve anti-theft. In addition, the existing tumb...
