Description

A kind of multiplex lock core

Technical field

The utility model relates to lockset technology, particularly relates to a kind of multiplex lock core.

Background technology

Former AB key lock generally has A, B two kinds of keys, a kind of lockset of being made up of from structures such as blades pellet (depth in hole is different, with the depth of threat of flat key shallow be not both the same).The effect of A, B key is, after people load onto this lock, A key can be given house decoration personnel by owner, passes in and out house door unblank for them, so also claim A key to be " finishing key "; After finishing, it is indoor that owner does not need finishing personnel to enter, and after owner injects lockhole rotational lock core one turn (circle) with B key, A key just loses the function of unblanking, so B key is also named " house-owner's key ".The advantage of AB key lock is the needs that can meet people's decorating house, remove from when fitting up busy, to open the door key loss, or have the people harbored evil intentions to take advantage of the busy machine of finishing to copy enabling key etc., the unsafe factor after may avoiding fitting up, owner produced, also, after can avoiding finishing, the next trouble of lock strap and cost is changed in order to safety.

This case is it is important to note that the similar AB on market is latched in very large defect, and after owner opens, finishing personnel just do not leave, but still can drive into after the workman of some specialty knows skill of unblanking, and this just damages to personal safety as well as the property safety.Therefore, for above aspect, need reasonably to improve prior art.

Utility model content

For above defect, the utility model provides a kind of anti-theft pick-proof, anti-tinfoil, preventing universal key, zero to open, reduce the multiplex lock core of mutual opening rate mutually, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of multiplex lock core, comprise lock core body, described lock core body two ends arrange tapered end part, tail end respectively, and lock head branch center place is wherein with tapered end groove; The inner axle by more than two of described lock core body forms and with flexible shaft, lock core body is made up of some joints and blade is equipped with respectively in each joint upper and lower both sides of lock body, each blade is furnished with corresponding blade groove, what each saved connects torsion spring between two blades up and down, and this torsion spring pops up and upper/lower terminal is hung on two blades;

Described tapered end part with tapered end shell and this tapered end outer side arrange can the automatic recovery storehouse, meanwhile, described tapered end enclosure arranges the location structure be in many ways made up of 2-6 above square location structure; At blade center place with axis hole and at blade two ends with circular hole or notching construction.

Correspondingly, divide with lock head on adjacent lock core body lock body draw-in groove is set;

Described blade is atresia blade, or two ends are with circular hole or notching construction; Described flexible shaft is made up of one or two axle, and the lock body outside flexible shaft is equipped with locating shaft.

Described blade groove is combined by one and multiple tracks cell body, and blade is made up of some difform lamellar bodies.

The beneficial effect of multiplex lock core described in the utility model is:

(1) adopt this structure, after owner drove lock, the number of lock core can change with flexible shaft, and so the key of engineering staff just becomes invalid unblanking;

(2) lockset polygonized structure, is applicable to all lockset products, rational in infrastructure, has anti-technical unlocking, an advantage that anti-theft pick-proof, anti-tinfoil, preventing universal key, zero are opened mutually;

(3) key key number has more than 9000 more than hundred million, and preventing engineering is key operated;

(4), when being used on other lockset, because this kind of lock core arranges rationally, its cipher key combinations and number are very many, reduce mutual opening rate, reach " Bao Jia convoy " object.
