Abstract

The utility model discloses an anti-picking lock with balls, belonging to hardware products. The utility model is composed by the method that an anti-picking groove is milled on the side edge of the ball hole of an original ball lock core; an anti-picking ball is adopted. The utility model has the advantages of simple preparing process and strong anti-picking and safety performances. The anti-picking lock with balls can be produced without additional equipment by common lock plants. The anti-picking lock with balls has the advantages of low cost increase or no cost increase.

Description

Anti-picking lock with balls

The utility model discloses a kind of billiards lock structure that has improved.Be applicable to various cylinder locks, belong to the five metals industrial products.

At present domestic and international disclosed cylinder lock is all being taked certain measure aspect anti-the dialling, and for example Italian Xisha company, Japan all adopt " S " grooved.The multiaspect pellet shot from a slingshot is adopted in the Germany, and each state all adopts the special-shaped anti-pellet shot from a slingshot etc. of dialling at present.But these anti-group measures are all not ideal enough, generally can push aside with non-key method in a few minutes, do not have the burglary insurance effect.The utility model designs in order to overcome above said shortcoming.This utility model can improve the anti-performance of dialling of cylinder lock largely, and the general locking method of dialling was lost efficacy substantially.

Main points of the present utility model.Be to have adopted anti-pellet shot from a slingshot (7) and the anti-pellet shot from a slingshot (8) of dialling of projective table type dialled of I shape, be milled with the anti-allocating slot (13) of the T-shape that cooperates with worker's type pellet shot from a slingshot at the pellet shot from a slingshot hole of lock core side, when dialling lock, worker's type pellet shot from a slingshot (7) is allocated in the usefull space of anti-allocating slot (13), lock core just can rotate, but turn over certain angle α, worker's type pellet shot from a slingshot (7) just slips in the anti-allocating slot (13) of T-shape, and lock core can not be rotated further.But can not unblank this moment, played the anti-safety effect of dialling.The anti-pellet shot from a slingshot (8) of dialling of projective table type is contained in the pellet shot from a slingshot hole of normal lock core, during poking lock, all is to dial pellet shot from a slingshot again after elder generation grapples lock core for choosing pellet shot from a slingshot with the two kinds groups of methods of pellet shot from a slingshot that fall.Blocking as shown in Figure 5 that boss makes progress is too heavy to carry, and boss can be broken the pellet shot from a slingshot rule that falls from inside to outside downwards when falling pellet shot from a slingshot, make its inefficacy.The anti-pellet shot from a slingshot of dialling of I shape (7) and boss type (8) can be processed on existing pinball game with molding cutter, and T-shape prevents that the available molding cutter of allocating slot (13) processes on drilling and milling machine or special purpose machine tool.

The anti-group effect of the utility model is all stronger than existing cylinder lock, and general locksmithery all can produce, and technology is simple, does not increase part, and the cost increase is very little.The normal use with present cylinder lock is as good as.

Accompanying drawing 1 is an anti-pulling pellet lock tapered end assembling sectional view.1 is that key, 2 is lock core among the figure, and 3 is lock housing, and 4 is last pellet shot from a slingshot (plain edition), and 5 are following pellet shot from a slingshot (plain edition), 6 is the pellet shot from a slingshot spring, and 7 are the anti-group pellet shot from a slingshot of worker's type, and 8 is the anti-pellet shot from a slingshot of dialling of projective table type, and 9 are the location pellet shot from a slingshot, 10 is collar, and 11 is shifting fork piece, and 12 is sealing cap.

Accompanying drawing 2 is anti-type pellet shot from a slingshot and anti-principle master sectional views of dialling of anti-allocating slot of exchanging work.2 is lock core among the figure, and 5 are following pellet shot from a slingshot, and 7 dial pellet shot from a slingshot for worker's type is anti-, and 13 is that T-shape is prevented allocating slot master sectional view.

Accompanying drawing 3 is the anti-pellets shot from a slingshot of dialling of worker's type.

Accompanying drawing 4 is the anti-pellets shot from a slingshot of dialling of boss type.

Accompanying drawing 5 is the anti-pellet anti-pull principle master sectional views of dialling of projective table type.

Accompanying drawing 6 is a left side, the anti-allocating slot position of T-shape sectional views.

Accompanying drawing 7 is the anti-allocating slot position of T-shape vertical views.

Anti-pulling pellet lock of the present utility model, the every handle of worker's type pellet (7) is locked to 1 of few usefulness. The projective table type pellet is every using at least 3. These two kinds of pellets can also use simultaneously and can use respectively. Worker's type is better than anti-group of pellet anti-pull performance of boss type.

Claims

1, a kind of anti-pulling pellet lock that is made of shell [3], lock core [2], pellet shot from a slingshot [4,5] pellet shot from a slingshot springs [6] and other part is characterized in that the lock core marble hole side milling has T-shape to prevent allocating slot [13].

2, it is characterized in that according to the said anti-pulling pellet lock of claim 1 said anti-group pellet shot from a slingshot (7) is to be processed into I shape.

3, want 1 and 2 said anti-pulling pellet locks according to right, it is characterized in that said T-shape prevents that the anti-size of dialling pellet shot from a slingshot (7) of allocating slot (13) and worker's type matches.

4, it is characterized in that in the pellet shot from a slingshot hole of existing cylinder lock, being equipped with the anti-pellet shot from a slingshot (8) of dialling of projective table type according to the said anti-pulling pellet lock of claim 1.
