Abstract

An anti-theft lock core with angled and staggered marbles comprises a key, an inner lock core and an outer lock core. A plurality of round holes are formed on the inner lock core and the outer lock core; a top marble, a bottom marble and a spring are arranged in sequence from inside to outside on each round hole; a key hole is formed inside the inner lock core; a door bolt is arranged in the key hole; and a tooth socket is formed on the key. Staggered structures with certain distances and angles are arranged among the round holes; each staggered structure adopts a structure of staggered marbles formed in the key hole after the top marble, the bottom marble and the spring are mounted; and the key hole is in the shape of a triangle. The utility model has the advantages of simple structure and low production cost, and can be made successfully by utilizing the prior art.

Description

Pellet shot from a slingshot has angular misalignment intersection anti-theft lock

Technical field:

The utility model relates to a kind of anti-theft lock, specifically is a kind of anti-theft lock that utilizes the angled dislocation of pellet shot from a slingshot to intersect.

Background technology:

Continuous development along with economic civilization, people are to seem very important of the safety of self property, yet the theftproof lock that occurs is to adopt parallel construction between the hoodle mostly at present, unlocking tool can enter lock core hole easily, this structure be latched in anti-theft feature a little less than, safety factor is lower, exists certain potential safety hazard, and the situation that a key can be opened two locks sometimes can appear, bring loss for virtually people's learning life.

The utility model content:

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of pellet shot from a slingshot chi structure that has is provided, and makes unlocking tool can not enter the anti-theft lock of keyhole easily.

The utility model is to realize like this;

A kind of pellet shot from a slingshot has angular misalignment intersection anti-theft lock, form by key, internal cylinder, outer lock core, it is characterized in that: on internal cylinder and outer lock core, be equipped with a plurality of circular holes, circular hole is provided with top bullet, end bullet, spring from inside to outside successively, be provided with keyhole in internal cylinder inside, door bolt is arranged in keyhole, teeth groove is arranged on the key.

Be to adopt the dislocation chi structure that has certain distance that certain angle is arranged between the described circular hole, this chi structure is to load onto a kind of pellet shot from a slingshot dislocation chi structure that forms in keyhole behind top bullet, end bullet, the spring.

Described keyhole is the keyhole of triangle.

Advantage of the present utility model is: keyhole is designed to the triangular shape structure, this lock core adopts pellet shot from a slingshot that the angular cross misconstruction is arranged, have only ought be on the key each teeth groove all with the pellet shot from a slingshot that the angular cross dislocation is arranged to can successfully unblanking just now at once, this design can be avoided the various losses that cause because of staggering, accomplish key and phase-locked corresponding purpose, increased the difficulty of unblanking.In this structure, also designed door bolt, can avoid other illegal instruments to enter in the lock well, played a protective role.The utility model is simple in structure, cost of production is low, utilizes producing that prior art all can be very well.

Description of drawings:

Fig. 1 is the utility model outer lock core and internal cylinder structural representation

Fig. 2 is the utility model outer lock core and internal cylinder schematic cross-section

Fig. 3 is the utility model key schematic diagram

Among the figure: 1, key; 2, internal cylinder; 3, outer lock core; 4, top bullet;

5, end bullet; 6, spring; 7, door bolt; 8, teeth groove; 9, keyhole;

10, circular hole.

The specific embodiment:

As shown in Figure 1 to Figure 3:

A kind of pellet shot from a slingshot has angular misalignment intersection anti-theft lock, form by key 1, internal cylinder 2, outer lock core 3, on internal cylinder 2 and outer lock core 3, be equipped with a plurality of circular holes 10, circular hole 10 is provided with top bullet 4, end bullet 5, spring 6 from inside to outside successively, be provided with keyhole 9 in internal cylinder 2 inside, door bolt 7 is arranged in keyhole 9, teeth groove 8 is arranged on the key 1.

Be to adopt the dislocation chi structure that has certain distance that certain angle is arranged between the described circular hole 10, this chi structure is to load onto a kind of pellet shot from a slingshot dislocation chi structure that forms in keyhole behind top bullet 4, end bullet 5, the spring 6.

Described keyhole 9 is the keyhole of triangle.

When key 1 is unblanked, when the top bullet 4 in all corresponding circular hole 10 of all teeth groove 8 set on the key 1, just lock can be opened, wherein be provided with a door bolt 7, can prevent to destroy because of other sharp objects enter to rise in the lock 2 li of internal cylinder.Keyhole of the present utility model is designed to triangular shape structure and lock core and adopts pellet shot from a slingshot to intersect misconstruction to cooperate, have only when each teeth groove all with intersect the pellet shot from a slingshot that misplaces to can successfully unblanking just now at once, this design can be avoided the various losses that cause because of staggering, accomplishes key and phase-locked corresponding purpose.The utility model is simple in structure, cost of production is low, utilizes producing that prior art all can be very well.
