Abstract

The utility model provides a high key precision lock core with six slots, comprising a lock head body, and the lock core which is arranged inside the lock head body. The high key precision lock core with six slots is characterized in that a lock core hole is provided with six slot holes of the slots with at least two different kinds of widths in an axial position. Marbles which are matched with the six slot holes are arranged inside the six slot holes respectively. The high key precision lock core with six slots has the advantages of high antitheft performance and safety.

Description

The high secret key degree of six grooves anti-theft lock

The utility model relates to the high secret key degree of a kind of improved six grooves anti-theft lock.

At present mostly be single groove greatly, mostly be 16 groups of pellets shot from a slingshot of cross four grooves most and form by key operated lock core.But its theftproof performance still can not satisfy the antitheft requirement of present height.

In view of above reason, the purpose of this utility model is for a kind of high secret key degree of six grooves anti-theft lock with high theftproof performance, safety is provided.

The purpose of this utility model is achieved in that the utility model comprises tapered end, is arranged in the lock core of tapered end, it is characterized in that lock core hole is six slotted eyes that the groove of at least two kinds of different in width is arranged on the axial location, the pellet shot from a slingshot (referring to Fig. 1, Fig. 2) that is complementary with it is housed respectively in six slotted eyes.

The groove (referring to Fig. 2) that three kinds of different in width are arranged in the above-mentioned lock core hole.

Lock core hole on the above-mentioned lock core is blind hole (referring to Fig. 1), increases lock core intensity.

The distance different (referring to Fig. 1) of first group of pellet shot from a slingshot of at least two row's pellets shot from a slingshot from the tapered end front surface arranged in the above-mentioned lock core hole.

Above-mentioned pellet shot from a slingshot adopts through heat treated steel marble, the hardness height, and anti-drilling, theftproof is good.

Compare with existing lock core, this practicality newly has following advantage:

1, the width of the groove in lock core six slotted eyes has two kinds of specifications at least, and lock core can be by four groups of pellets shot from a slingshot of every groove, and two every group, amount to 48 pellets shot from a slingshot, 24 pellet shot from a slingshot springs compositions, its secret key degree reaches 6 * 7 * 10 ⁴, mutual opening rate has only 0.5 ‰;

2, any one group of pellet shot from a slingshot in 24 groups of pellets shot from a slingshot is not in place, the distance of any one group of high tapered end front surface of pellet shot from a slingshot is not inconsistent with the distance of key tooth flower, the width of the thickness of key faceted pebble and six grooves is not inconsistent all and can not unblanks, not only have good anti-drilling, pick-proof, anti-saw, the anti-performance of unloading, and the theftproof performance height, insurance, secret, safety;

3, modern design, rational in infrastructure, easy to manufacture, can with the supporting uses of door lock such as existing single tongue, two tongue, perpendicular tongue, monolock head or twin-lock head all are suitable for, and can resist very strong impact force, and 24 groups of pellets shot from a slingshot are built-in;

4, the key supporting with lock core is the key of six ribs, 24 tartars, and the depth bounds 0.5～2.5mm of tartar can make up arbitrarily, improves its safe antitheft performance.

Describe the novel embodiment of this reality in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the Key structure schematic diagram.

Lock core 1 is arranged in tapered end 2, and bolt 3 is equipped with in its bottom.The fixedly cannelure of bolt is arranged at tapered end bottom, and collar 4 embeds in the ring shaped slots, like this when unblanking, lock core can not be pushed so that when getting key lock core also be unlikely to be drawn out.Lock core hole 5 is for there being six slotted eyes of the different groove of three groups of width.Six slotted eyes are blind hole.Key tooth flower pellet shot from a slingshot 6 in six grooves be with six slotted eyes 5 in the pellet shot from a slingshot of groove three kinds of format diameter of mating.The length joint difference of these tartar pellets shot from a slingshot is five kinds tartar pellet shot from a slingshot for the length of 0.5mm.Every groove has four groups of pellets shot from a slingshot, two every group, comprises 7, four pellet shot from a slingshot springs 8 of four flat pellets shot from a slingshot.First group of pellet shot from a slingshot of six row's pellets shot from a slingshot is different respectively from the distance of tapered end front surface 9 in six slotted eyes.First group of pellet shot from a slingshot of six grooves all adopts through Overheating Treatment, RC hardness be 55～60 with the similar steel marble of drill bit hardness.Referring to Fig. 3, key 10 adopts front end that six rib keys of constant slope are arranged, and every rib is milled with four kinds of different tartars.Having only 24 groups of pellets shot from a slingshot of six grooves in 24 tartars of six rib keys and the lock core and first group of pellet shot from a slingshot to match from the distance of tapered end front surface could rotational lock core, opens or the locking door lock.

Six rib keys and six rib lock cores by its best fit, make it can successfully insert or extract out six groove lock cores.There is individual roundlet breach 11 bundle of circles of six rib keys top, to mark, just can successfully insert key or extraction key over against any groove of six groove lock cores top broad, and other any direction all can not be inserted key.

Claims

1, the high secret key degree of six grooves anti-theft lock comprises tapered end, is arranged in the lock core of tapered end, it is characterized in that lock core hole is six slotted eyes that the groove of at least two kinds of different in width is arranged on the axial location, is equipped with the pellet shot from a slingshot that is complementary with it respectively in six slotted eyes.

2, the high secret key degree of six grooves as claimed in claim 1 anti-theft lock is characterized in that three kinds of grooves that width is different are arranged in the described lock core hole.

3, the high secret key degree of six grooves as claimed in claim 1 anti-theft lock is characterized in that the lock core hole on the described lock core is a blind hole.

4, the high secret key degree of six grooves as claimed in claim 1 anti-theft lock is characterized in that having in the described lock core hole at least two distance differences of arranging first group of high tapered end front surface of pellet shot from a slingshot of pellets shot from a slingshot.

5, the high secret key degree of six grooves as claimed in claim 1 anti-theft lock is characterized in that described pellet shot from a slingshot adopts through heat treated steel marble.
