Abstract

The utility model relates to a lock core of a door lock which includes the outer sleeve of a lock core shaft and a lock core shaft arranged in the outer sleeve of the lock core shaft; a movable vane is arranged in the inner hole of the lock core shaft; an offset spring is arranged between the movable vane and the lock core shaft; a clamping sleeve is arranged between the outer sleeve of the lock core shaft and the lock core shaft; vane caulking grooves are arranged on the two sides of the clamping sleeve which is opposite to the movable vane on the locking position; grooves are respectively arranged on the side wall of the movable vane and the opposite inner wall of the clamping sleeve; a through hole slot is arranged on the lock core shaft opposite to the groove; slide lock pieces are arranged in the through hole slot; one ends of each slide lock piece are connected in a whole by lateral pins; marble holes are oppositely arranged in the clamping sleeve and the lock core shaft; marbles and springs are arranged in the marble holes. The lock core of a door lock overcomes the defects of tatty lock core structure design, poor safety performance and bad operation hand feeling of a common vane lock in the prior art. The safety performance of the lock core of the vane lock is greatly improved by the design; the lock core of a vane lock has the advantages of compact structure, low failure rate, flexible opening and closing, high reliability, etc.

Description

A kind of 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, be between lock core shaft's overcoat and the lock core shaft chuck to be 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, one end of each sliding lock spare is fused by lateral pin, 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.

Between lateral pin and lock core shaft, be provided with spring.

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

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.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1.

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 2, 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, installing sliding lock spare 14 in the through-hole groove 10, one end of each sliding lock spare 14 is fused by lateral pin 15, 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 in the pellet shot from a slingshot hole 11, spring 13.Between lateral pin 15 and lock core shaft 2, be provided with spring 16.The pellet shot from a slingshot hole 11 outer glands 17 that are provided with of chuck 6.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 18 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, when lock core shaft 2 rotates together, lateral pin 15 spring 16 between compression lateral pin 15 and the lock core shaft 2 that matches with groove 9, and sliding lock spare 14 pushed groove 8 on moving vane 3 sidewalls, make lateral pin 15 and sliding lock spare 14 along with lock core shaft 2 rotates together, reach the purpose of unblanking after key is rotated further and puts in place.When the backward rotation key puts in place, groove 9 on groove 8 on moving vane 3 sidewalls and chuck 6 inwalls is relative, spring 16 discharges to reset sliding lock spare 14 release grooves 8, lateral pin 15 is entered groove 9, after extracting key, upper and lower pellet shot from a slingshot 12 and each moving vane 3 slippages dislocation, simultaneously, moving vane 3 dop that preset at its two ends under the effect of back-moving spring 5 18 embeds in the blade caulking groove 7 of chuck 6, the multiple locking of lock core.
