Description

Door lock core

Affiliated technical field

The utility model relates to a kind of door lock core.

Background technology

Traditional door lock core particularly only adopts the door lock core of blade as Cipher mechanism, all is that the blade arranged by difference and the groove fit of lock core shaft's overcoat lock, and therefore, structure design is simpler and cruder, theftproof performance a little less than; In use, the key of insertion swings easily, and the feel of operation is not good, and therefore comparatively speaking, tradition adopts blade also higher as the fault rate of the door lock core of Cipher mechanism, and this certainly will influence its applying in lockset.

Summary of the invention

Simple and crude in order to overcome in the prior art common door lock pin structure design, theftproof performance is weak, the not good problem of feel of operation, the utility model provides a kind of door lock core, the good reliability that compact conformation, the theftproof performance of this door lock core is strong, fault rate is low, use.

The technical scheme that its technical problem that solves the utility model adopts is: comprise the lock core shaft in lock core shaft's overcoat and the lock core shaft's overcoat, moving vane is arranged in the endoporus of lock core shaft, between moving vane and the lock core shaft back-moving spring is set, between lock core shaft's overcoat and the lock core shaft chuck is set, on the both sides of the relative chuck in locking position, be provided with the blade caulking groove with moving vane, on the inwall of the sidewall of moving vane and relative chuck groove is set respectively, offer through-hole groove in the lock core shaft relative with groove, installing sliding lock spare in the through-hole groove, the relative pellet shot from a slingshot hole of offering in chuck and the lock core shaft, pellet shot from a slingshot is installed pellet shot from a slingshot in the hole, spring.

Be provided with gland outside the pellet shot from a slingshot hole of chuck.

Through-hole groove is corresponding with each moving vane independently to be provided with or to be a continuous elongated slot, and the sliding lock spare of installing in the through-hole groove is respectively steel ball or roller.

Folder is established fixed blade in the lock core shaft between adjacent moving vane.

The utility model is by above-mentioned specific design, adopts the double code mode of blade, pellet shot from a slingshot to improve the theftproof performance of vane type door lock core greatly, has compact conformation, fault rate is low, switchings is flexible, reliable high advantage.

The specific embodiment

As shown in the figure, the utility model comprises the lock core shaft 2 in lock core shaft's overcoat 1 and the lock core shaft's overcoat 1, moving vane 3 is arranged in the endoporus 4 of lock core shaft, between moving vane 3 and the lock core shaft 2 back-moving spring 5 is set, between lock core shaft's overcoat 1 and the lock core shaft 2 chuck 6 is set, on the both sides of the relative chuck 6 in locking position, be provided with blade caulking groove 7 with moving vane 3, on the inwall of the sidewall of moving vane 3 and relative chuck 6 groove 8 is set respectively, 9, with groove 8, offer through-hole groove 10 in the 9 relative lock core shafts 2, through-hole groove 10 and each moving vane 3 be corresponding independently to be provided with or to be a continuous elongated slot, installing sliding lock spare in the through-hole groove 10, the sliding lock spare of installing is respectively steel ball 15 or roller in the through-hole groove 10.The relative pellet shot from a slingshot hole 11 of offering in chuck 6 and the lock core shaft 2, installing pellet shot from a slingshot 12, spring 13 in the pellet shot from a slingshot hole 11, the pellet shot from a slingshot hole 11 outer glands 14 that are provided with of chuck 6.Folder is established fixed blade 16 in the lock core shaft 2 between the adjacent moving vane 3, and fixed blade 16 can be provided with one or more pieces, can play and stablize key and anti-effect of dialling.When unblanking, insert key, key make progress pushing tow move the son 12, make, mating face that following pellet shot from a slingshot is 12 and lock core shaft 2, the mating face that chuck is 6 flushes, the dop 17 that the resistance that key overcomes back-moving spring 5 simultaneously presets each moving vane 3 two ends breaks away from the blade caulking groove 7 and the slippage alignment of chucks 6 both sides, groove 8 on each moving vane 3 is alignment simultaneously also, under the drive of key, moving vane 3, lock core shaft 2 rotates together, one end of steel ball 15 or roller be brought on moving vane 3 sidewalls groove 8 and along with lock core shaft 2 rotates together, reach the purpose of unblanking.When the backward rotation key puts in place, groove 9 on groove 8 on moving vane 3 sidewalls and chuck 6 inwalls is relative, when extracting key, upper and lower pellet shot from a slingshot 12 and each moving vane 3 slippages dislocation, and an end of steel ball 15 or roller is pushed groove 9 on chuck 6 inwalls by groove 8, simultaneously, moving vane 3 dop that preset at its two ends under the effect of back-moving spring 5 17 embeds in the blade caulking groove 7 of chuck 6, the multiple locking of lock core.In the above-described embodiments, the close tooth of key both sides adopts asymmetrical design, and key can only insert lock core by a direction, has not only improved reliability, and has greatly reduced mutual opening rate.
