Abstract

The invention relates to a lock core of blade lock, comprising sleeve of lock core shaft and lock core shaft in the sleeve. The movable blade is set in the inner hole of lock core shaft. Reset spring is set between the movable blade and the lock core shaft. Concave grooves are set at the side wall of movable blade and the inner wall of opposite sleeve of lock core shaft respectively. Through hole groove is set on the lock core shaft opposite to the concave groove and sliding lock part is set in the through hole groove. Fixing blade is clamped between adjacent movable blades. The invention conquers lacks that the design of lock core structure of ordinary blade lock in prior technology is simple, anti-theft performance is more feeble, operation handle is not good. By design mentioned above, anti-theft performance of lock core of blade lock is improved greatly and it is provided with compact structure, low fault rate, flexible open and close, and high reliability.

Description

A kind of blade lock pin

Affiliated technical field

The present invention 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 invention 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 solution adopted for the present invention to solve the technical problems 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 present invention 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 invention is described.

Fig. 1 is a structural representation of the present invention;

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 present invention.

The specific embodiment

As shown in the figure, the present invention includes 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.
