Description

Straight moving open-type lock cylinder assembly

The utility model relates to the lock cylinder assembly, particularly a kind of straight moving open-type lock cylinder assembly.

Existing lock cylinder assembly is made up of pellet shot from a slingshot, lock core, core retainer plate, driving member, on lock core and core retainer plate, all be processed with the hole that holds pellet shot from a slingshot, insert key lock core marble is alignd with the core retainer plate gap with lock core with core retainer plate pellet shot from a slingshot gap, the twisting key makes lock core drive driving member formation in the rotation process in core retainer plate and unblanks.The lock cylinder assembly is compared with the mechanical code lock core assembly with the electronic lock cylinder assembly, has to unblank conveniently, and without power supply, the reliable advantage of mechanical action, shortcoming are to twist off key when unblanking easily.Chinese patent 92215055.9 proposes a kind of tapered end and lock core is plate shaped in order to address this problem, setting pin pearl wherein is with plane dispersed arrangement, according to its position and quantity, difference has the scheme of various assembled arrangement forms, its shortcoming is that structure is not compact, be not easy to make poor practicability.

The purpose of this utility model provides a kind of Shi Buhui of unblanking and the key problem occurs twisting off, and compact conformation, is convenient to make, practical straight moving open-type lock cylinder assembly.

The utility model is to realize like this, hold the pellet shot from a slingshot that cooperates with key bit vertical arrangement of core sidewall, be provided with on the core body lock core that cooperates the keeping parallelism motive position with core retainer plate can be in core retainer plate before and after parallel motion, inserting key makes lock core marble align with the core retainer plate gap with lock core with core retainer plate pellet shot from a slingshot gap, push away or pull back lock core more forward, make lock core in core retainer plate, drive driving member formation in the parallel motion process and unblank.

The utility model compared with prior art its remarkable advantage is, the active force of unblanking is reasonable, has when the key problem appears twisting off in the Shi Buhui of unblanking, and the key of its thin-narrow shape is easy to carry.In core retainer plate, do not rotate owing to vertically arrange the lock core that holds pellet shot from a slingshot at the core sidewall, thus lock core, core retainer plate can be made into slim, compact conformation, handsome in appearance.With existing lock cylinder assembly same thickness condition under can adorn many row's pellets shot from a slingshot in the lock core, core retainer plate, it is many key operated high security type lock cylinder assembly to become a kind of usefulness.Still adopted and experienced all sorts of the deciphering principle that time check proves that effective lock core marble cooperates with key bit, be convenient to the lockmaking industry and utilize the manufacturing of existing equipment technology.
