Problems solved by technology

Once the mechanical pin lock cylinder is assembled, the teeth are fixed, and the key is easy to be copied. Therefore, once the key is lost, it will cause a safety hazard
At present, the biggest disadvantage of the mechanical lock cylinders with changeable teeth on the market is that the change is single and cannot be reset.

Embodiment Construction

[0014] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0015] The present invention mainly consists of a lock cylinder 1, a lock end 2, a working flat head 3 (7 pieces), a working pin 4 (7), a pin spring 5, and a changing pin 29 (6 in total: 6, 9, 12, 14, 16, 18), changing steel balls 30 (a total of 6 pieces: 7, 10, 11, 13, 15, 17), changing flat heads 8 (a total of 6 pieces), working flat heads 19, working pins 20, reset transition pins 31 (7 pieces in total: 21, 23, 24, 25, 26, 27, 28), reset transition flat head 22 and the like. The present invention mainly adopts the lock cylinder 1 to be installed in the lock head 2, the working pin 4 (7 pieces) is housed in the lock core 1, the working flat head 3 (7 pieces) and the pin spring 5 are housed in the lock head 2, The core 1 and the lock head 2 have the working surface A, C and the conversion pin working surface B respectively, and the lock core 1 and th...

Abstract

This invention is about a changeable mechanical lock chip, specifically a mechanical spring lockcore. On the lockcore and lockhead, it mainly adopts the working faces A,C with working springs and the working face B of switching springs, and the lockcore and lockhead have their own acceptance holes. In the acceptance holes of the lockcore are put back-moving and transitional springs and in those of the lockhead are back-moving and transitional flat heads. The switching steel balls are set between the working flat heads and the switching steel balls, switching between the working surfaces A,C and B. This structure is simple, compact and reasonable. The key can be used to change the lockcore and can switch and reset repeatedly and alternatively.

Description

technical field [0001] The invention relates to a variable tooth pattern mechanical lock core, in particular to a mechanical pin lock core, which belongs to the technical field of hardware fittings for daily use. Background technique [0002] Before the present invention was made, in the prior art, the mechanical pin lock core was generally made up of parts such as lock core, lock end, pin pin, flat head, and the combination of different pin pins has formed a key to open a lock. Once the mechanical pin lock cylinder is assembled, the teeth are fixed, and the key is easy to be copied. Therefore, once the key is lost, it will cause a safety hazard. At present, the biggest shortcoming of the mechanical lock cylinder with changeable tooth patterns sold on the market is that the change is single and cannot be reset. [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a simple, compact and reasonable structure; the key can be us...
