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 adopts the door lock core of blade as Cipher mechanism, and all the blade of only arranging 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, one end of lock core shaft's overcoat internal lock mandrel is chimeric with the switching piece that is hinged on the slip hinge, the switching piece matches with thumb wheel, on the inwall of the sidewall of moving vane and relative lock core shaft's overcoat 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, with moving vane the blade folder is set on the relative lock core shaft's outer casing inner wall in locking position, is provided with the blade caulking groove in the blade folder.

Corresponding independent setting the with each moving vane of through-hole groove, the sliding lock spare of installing in the through-hole groove is a steel ball.

Through-hole groove is a continuous elongated slot, and the sliding lock spare of installing in this through-hole groove is a roller.

Be provided with annular groove in lock core shaft, annular groove is located with the spacer on the blade folder and is cooperated.

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

The utility model has improved the theftproof performance of vane type door lock core greatly by above-mentioned specific design, has compact conformation, fault rate is low, switching 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 of lock core shaft 2, between moving vane 3 and the lock core shaft 2 back-moving spring 4 is set, one end of lock core shaft's overcoat 1 internal lock mandrel 2 is chimeric with the switching piece 12 that is hinged on the slip hinge 11, the switching piece matches with thumb wheel 13, on the inwall of the sidewall of moving vane 3 and relative lock core shaft's overcoat 1 groove 5 is set respectively, 6, with groove 5, offer through-hole groove 7 in the 6 relative lock core shafts 2, installing sliding lock spare in the through-hole groove 7, with moving vane 3 blade folder 14 is set on relative lock core shaft's overcoat 1 inwall in locking position, be provided with blade caulking groove 15 in the blade folder 14, be provided with annular groove 16 in lock core shaft 2, annular groove 16 is located with the spacer 17 on the blade folder 14 and is cooperated.The specific embodiment of through-hole groove 7 and sliding lock spare can have multiple, and as shown in Figure 1, through-hole groove 7 is corresponding to each moving vane 3 a plurality of independent settings in lock core shaft 2, and the sliding lock spare of installing is a steel ball 8 in each through-hole groove 7; Or as shown in Figure 9, through-hole groove 7 is a continuous elongated slot in lock core shaft 2, and the sliding lock spare of installing is a roller 9 in this continuous through-hole groove 7.Folder is established fixed blade 10 in the lock core shaft 2 between adjacent moving vane 3.Fixed blade 10 can be provided with one or more pieces, can play and stablize key and anti-effect of dialling.When unblanking, insert key, key promotes the hinge 11 that slides forward, make the switching piece 12 and thumb wheel 13 interlocking interlocks of a side, the dop 18 that the resistance that key overcomes back-moving spring 4 simultaneously presets each moving vane 3 two ends breaks away from blade caulking groove 15 and the slippage alignment in the blades folder 14, groove 5 on each moving vane 3 is alignment simultaneously also, under the drive of key, moving vane 3, lock core shaft 2, switching piece 12 rotates with thumb wheel 13, one end of steel ball 7 or roller 8 be brought on moving vane 3 sidewalls groove 5 and along with lock core shaft 2 slips over 14 rotations of blade folder together, key is rotated further back thumb wheel 13 actions that put in place and reaches the purpose of unblanking.During the backward rotation key, thumb wheel 13 counteragents, when key puts in place, groove 6 on groove 5 on moving vane 3 sidewalls and lock core shaft's overcoat 1 inwall is relative, when extracting key, and each moving vane 3 slippages dislocation, and an end of steel ball 7 or roller 8 is pushed groove 6 on lock core shaft's overcoat 1 inwall by groove 5, simultaneously, moving vane 3 dop that preset at its two ends under the effect of back-moving spring 4 18 embeds in the blade caulking groove 15 of blade folder 14, the lock core double locking.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.
