Abstract

The utility model relates to a lock core of a blade lock, comprising a sleeve of a lock core shaft and a lock core shaft in the sleeve, wherein, a movable blade is arranged in an inner hole of the lock core shaft; a reset spring is arranged between the movable blade and the lock core shaft; grooves are respectively arranged at the side wall of the movable blade and the opposite inner wall of the sleeve of the lock core shaft, a via hole groove is arranged on the lock core shaft opposite to the groove, and a sliding lock part is arranged in the via hole groove; a fixed blade is clamped between adjacent movable blades. The utility model overcomes the defects of crude structural design, weaker anti-theft performance and poor operation hand feeling of the common lock core of the blade lock in the prior art, greatly improves the anti-theft performance of the lock core of the blade lock through the design, and has the advantages of compact structure, low failure rate, flexible locking and unlocking, and high reliability.

Description

A kind of blade lock pin

Affiliated technical field

The utility model relates to a kind of blade lock pin.

Background technology

Traditional blade lock pin, all the blade of only arranging by difference and the groove fit of lock core shaft's overcoat lock, 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 comparatively speaking, the fault rate of traditional blades lock pin is also higher, and this certainly will influence blade lock core applying in lockset.

Summary of the invention

Simple and crude in order to overcome in the prior art common blade lock pin structure design, theftproof performance is weak, the not good problem of feel of operation, the utility model provides a kind of blade lock pin, the good reliability that compact conformation, the theftproof performance of this blade lock pin 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, 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, installing sliding lock spare in the through-hole groove with groove.

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.

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

The utility model has improved the theftproof performance of blade lock pin greatly by above-mentioned specific design, has compact conformation, fault rate is low, switching 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;

Fig. 4 is the C-C sectional view of Fig. 2;

Fig. 5 is the structural representation of another embodiment of the utility model.

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, on the inwall of the sidewall of moving vane 3 and relative lock core shaft's overcoat 1

groove

5,6 is set respectively, offer through-hole groove 7 in the lock core shaft 2 relative, installing sliding lock spare in the through-hole groove 7 with groove 5,6.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 5, 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 overcomes draw-in groove 12 and the slippage alignment that dop 11 release lock mandrel overcoats 1 inwall that the resistance of back-moving spring 4 presets each moving vane 3 two ends presets, groove 5 on each moving vane 3 is alignment simultaneously also, when moving vane 3 and lock core shaft 2 rotate together under the drive of key, one end of steel ball 8 or roller 9 be brought on moving vane 3 sidewalls groove 5 and 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 6 on groove 5 on moving vane 3 sidewalls and lock core shaft's overcoat 1 inwall is relative, when extracting key, each moving vane 3 slippages dislocation, and an end of steel ball 8 or roller 9 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 11 embeds the draw-in groove 12 that lock core shaft's overcoat 1 inwall presets, 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.
