Abstract

The utility model relates to a spiral marble lock, comprising an outer shell, a lock core, spring pressing springs which are arranged in marble holes, inner marbles and outer marbles, and is characterized in that the axial direction of the marble holes is vertical to the axial direction of the lock core. The marble holes are in spiral distribution along the axial direction of the lock core. The utility model has the advantages of high safety coefficient, good theftproof performance, and simple and reasonable structure. Because the arrangement and distribution mode of the existing marbles, the inner marbles and the outer marbles are respectively hidden in the lock shell and the lock core. In addition, different orientation can be in screw distribution on the cylinder face of a lock head. So the utility model has omnibearing control performance.

Description

Screw type cylinder lock

The utility model relates to a kind of cylinder lock, relates in particular to a kind of spiral cylinder lock, and it mainly comprises shell, lock core, is arranged on marble pressuring spring and inside and outside pellet shot from a slingshot composition in the lock core.

The cylinder lock that present people generally use, its primary structure principle is: be processed with the pellet shot from a slingshot hole on lock housing, pellet shot from a slingshot and marble pressuring spring are contained in the pellet shot from a slingshot hole, when key injects lock core, pellet shot from a slingshot in the lock core all with cylinder (the being insurance coverage) trim mutually of lock core, rotational lock core is locked and promptly is opened; When key was extracted out, the pellet shot from a slingshot in the lock core was under the effect of marble pressuring spring, and the pin fixed lock core can not rotate it, and lock is promptly by locking.This class cylinder lock is owing to due to its structure, in use have the following disadvantages: 1., safety factor is low this, generally lock six, seven of the many persons of quantity of pellet shot from a slingshot, and two, three of few persons, permutation and combination method is limited, and the repetitive rate of key is higher.2., theftproof performance is poor because the pellet shot from a slingshot group concentrates on the same straight line, inside and outside pellet shot from a slingshot easily by foreign matter on insurance coverage separately, lock is opened.3., outer pellet shot from a slingshot exposes easily by after the drilling, inside and outside pellet shot from a slingshot can be released outside the lock core with certain instrument, thereby lock is opened.4., along with the increase of pellet shot from a slingshot group row number, the mechanical performance of lock core also correspondingly weakens, lock core is easily bad and can't realize comprehensive distribution pellet shot from a slingshot and control by sled.

The purpose of this utility model is exactly a kind of vi have high safety that provides in order to overcome existing weak point in the above-mentioned prior art, and theftproof performance is good, and is simple and reasonable, the spiral cylinder lock that pellet shot from a slingshot can comprehensive distribution.

The purpose of this utility model realizes by following measure: this spiral cylinder lock mainly comprises shell, lock core, is arranged on spring stage clip and inside and outside pellet shot from a slingshot in the pellet shot from a slingshot hole, wherein, the axis direction in pellet shot from a slingshot hole and the axis direction of lock core are perpendicular, and the pellet shot from a slingshot hole is in spiral distribution along the lock core axis direction.

In lock core, also be provided with the anti-drilling pellet shot from a slingshot of making by Hardmetal materials in the utility model.The pellet shot from a slingshot hole can be single spiral along the lock core axis direction and distribute, and also can be double spiral and distribute.Outer pellet shot from a slingshot be shaped as convex structure, also can be circle or taper shape.

The advantage that the utility model is compared with prior art possessed is: vi have high safety, and theftproof performance is good, and is simple and reasonable, and mutual opening rate is low between key.Owing to changed the arrangement mode of existing pellet shot from a slingshot, make inside and outside pellet shot from a slingshot be built in respectively in lock housing and the lock core, and pellet shot from a slingshot can be on the tapered end cylinder spiral different everywhere orientation that distributes, so have the performance of comprehensive control.The anti-drilling pellet shot from a slingshot of being made by hard material also is installed in this cylinder lock, and the anti-cutting performance of anti-brill is good, a kind of mechanical lock of implementing and promoting that is suitable for of can yet be regarded as.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the front view of the utility model tapered end part.

Fig. 2 is the front view of the utility model key.

The utility model is done with detailed description below in conjunction with accompanying drawing:

As shown in Figure 1: this spiral cylinder lock mainly comprises shell (1), lock core (2), dead bolt (8), is arranged on spring stage clip (4) and inside and outside pellet shot from a slingshot (5) (6) in the pellet shot from a slingshot hole (3), wherein, the axis direction in pellet shot from a slingshot hole (3) and the axis direction of lock core are perpendicular, the pellet shot from a slingshot hole is in spiral distribution along the lock core axis direction, can be single spiral and distribute, also can be double spiral and distribute.Outer pellet shot from a slingshot (6) be shaped as convex structure (also can be circle or taper shape).In lock core, also be provided with the anti-drilling pellet shot from a slingshot of making by Hardmetal materials (7).

When the utility model uses, screw in the keyhole with key (its structure as shown in Figure 2), make in teeth groove also in spiral distribution on it and the lock core pellet shot from a slingshot on the spiral road corresponding one by one, its insurance coverage is by trim, and key is locked and promptly is unlocked.

According to the principle of this lock core, can manufacture door lock, padlock, lock for motorcycle and bicycle lock etc.

Claims

1, a kind of spiral cylinder lock, it mainly comprises shell (1), lock core (2), is arranged on marble pressuring spring (4) and inside and outside pellet shot from a slingshot (5) (6) in the pellet shot from a slingshot hole (3), of the present utility model being characterised in that: the axis direction of the axis direction of pellet shot from a slingshot hole (3) and lock core (2) is perpendicular, and pellet shot from a slingshot hole (3) are in spiral distribution along the lock core axis direction.

2, spiral cylinder lock according to claim 1 is characterized in that: also be provided with the anti-drilling pellet shot from a slingshot of being made by hard material (7) in lock core.
