Abstract

The utility model relates to an anti-theft lock for a vehicle, comprising a lock body and a key. The utility model is characterized in that the lock body and a steering shaft are integrated into a whole, that is the shaft center is provided with at least two cylindrical holes, and a spring is arranged at the bottom of each hole; cylindrical balls are placed on the springs, and the cylindrical balls are identical in length; a transverse pin vertically penetrates through a ball thereof, another cylindrical ball which is not equal to the cylindrical balls in length is placed additionally; the shaft sleeve which wraps the shaft center is provided with a through hole, and the through hole is matched with the cylindrical holes in the shaft center. A comb-shaped key is provided with cylindrical key bits which are matched with the keyhole in the shaft sleeve, and the sum of the length of the key bits and the length of the corresponding ball which is different from other balls in length is equal to the distance from the inner wall of the shaft sleeve to the keyhole. The utility model has the advantages of high anti-theft performance, artful design, simple structure, and convenient operation. Even if the lock is destroyed, the vehicle still can not be stolen.

Description

Anti-theft lock for vehicle

The utility model relates to a kind of anti-theft column lock, specifically a kind of anti-theft column lock of automobile-use.

Particularly automobile, motor bike are stolen in order to prevent power actuated vehicle, existing multiple anti-theft column lock, as long as but will lock breaking-up, just can steal vehicle, can not prevent effectively that promptly self-propelled vehicle is stolen.

, the purpose of this utility model ruins the anti-theft column lock of the automobile-use that vehicle also can't be stolen even providing a kind of lock.

The purpose of this utility model is realized by following technical scheme.

The utility model is made up of lock body, key, it is characterized in that: described lock body is made up of axle center, axle sleeve, pellet shot from a slingshot, spring and horizontal bolt, have at least two cylindrical holes on the axle center, each hole inner bottom part is adorned a spring, the identical cylinder-shaped marble of length is arranged on the spring, horizontal bolt vertically passes a wherein pellet shot from a slingshot, on the identical cylinder-shaped marble of length the different cylinder-shaped marble of length is housed, be placed in have on the axle sleeve outside the axle center with the axle center on cylindrical hole one end coupling, the other end is the through hole of key hole, and its key hole diameter is less than cylindrical hole diameter on the axle center.Comb shape have on the key with axle sleeve on the cylindrical key tooth that is complementary of key hole, its tooth is long identical to the distance of key hole mouth with the cylinder-shaped marble length sum and the sleeve lining of cooresponding different length.

The utility model has the advantages that therefore lock is ruined owing to the steering shaft with lock body and bearing circle fuses into one, steering shaft is also ruined, thereby also can't steal even ruin the lock car.

Another advantage of the present utility model is that design is ingenious, simple in structure, easy to use.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model Key structure scheme drawing.

Fig. 3 is the utility model opening scheme drawing.

Drawing reference numeral:

1, axle center, 2, axle sleeve, 3, pellet shot from a slingshot, 4, spring, 5, horizontal bolt, 6, key hole, 7, key bit.

Embodiment:

(referring to Fig. 1,2) have four cylindrical holes on axle center (1), each hole inner bottom part is adorned a spring, place the identical cylinder-shaped marble (3) of a length on it, horizontal bolt (5) vertically passes pellet shot from a slingshot in first hole (3), place different cylinder-shaped marble (3) again, be placed in to have on the axle sleeve (2) outside the axle center and go up cylindrical hole one end coupling with axle center (1), the other end is diameter is gone up the key hole (6) in cylindrical aperture less than axle center (1) a through hole, have on the key and the axle sleeve (2) of comb shape are gone up the cylindrical key tooth (7) that key hole (6) is complementary, and long cylinder-shaped marble (3) length sum and axle sleeve (2) inwall with cooresponding different length of its tooth is identical to the distance of key hole (6) mouth.

When (referring to Fig. 3) used, in the tooth insertion key hole (6) with key, key bit (7) promoted the pellet shot from a slingshot (3) of different length, thereby make pellet shot from a slingshot (3) be pushed into axle center (1) with length, be opening, fixedly key gets final product unlocking vehicle, and extracting key is the locking vehicle.If the car stealer pries open lock,, thereby axle center (1) can not be rotated and can't steal car because the pellet shot from a slingshot (3) that horizontal bolt (5) passes will not break away from axle center (1).
