Abstract

The utility model relates to a bicycle lock, and the lock body is installed on the outer case of the brake of the bicycle. The lock body is vertical with the plane surface of the brake or forms certain angle with the plane surface of the brake. By locking the lock, the bicycle can be locked, and the lock shaft of the lock body is inserted into the flute between the two baffles of the inner wheel of the brake at this moment. If the bicycle is pushed now, the inner wheel of the brake which shares the same shaft with the bicycle wheel rotates simultaneously with the bicycle wheel when the bicycle wheel rotates, and then the baffles of the inner wheel of the brake are blocked by the lock shaft. Therefore, the bicycle wheel can not rotate and the purpose of theft protection is achieved. The utility model has the advantages of reasonable design, easy manufacture, easy use and good anti-theft performance.

Description

A kind of bicycle lock

(1) technical field

The utility model relates to a kind of lock, particularly a kind of bicycle lock.

(2) background technology

Existing bicycle lock is divided into two classes substantially.One class is a spring lock, and this be is installed in lock body on the vehicle frame, and is easy to use, but puts robber, pick-proof poor performance.Another kind of is cable-type padlock and chain lock, though the incident of being cut end than spring lock intensity height, also often takes place this lock, and car separates with lock, and it is convenient inadequately to use, and locks and also loses easily.

(3) summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of reasonable in design, easy to manufacture, easy to use, bicycle lock that theftproof performance is good.

A kind of bicycle lock, lock body are installed on the shell of bicycle brake lock.

Described lock body is perpendicular to damper brake plane or angled with the damper brake plane.

In the use, when needing the lock car, the locking lock is got final product.At this moment, the lock shaft of lock body is inserted in the groove between two dividing plates of wheel in the damper brake.If at this moment push the machine, when bicycle quick rotates, also rotate synchronously with wheel with wheel in the coaxial damper brake of wheel, the dividing plate in the damper brake on the wheel will be stopped by lock shaft, reaches theft-proof purpose thereby wheel can't be rotated.

The utlity model has characteristics reasonable in design, easy to manufacture, easy to use, that theftproof performance is good.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A section-drawing of Fig. 1.

Wherein, 1, damper brake, 2, spring, 3, interior wheel, 4, shell, 5, brake cable, 6, lockhole, 7, dividing plate, 8, groove, 9, lock body.

(5) specific embodiment

Embodiment: structure of the present utility model as depicted in figs. 1 and 2, lock body 9 is installed on the shell of bicycle brake lock 1 and perpendicular to the plane of damper brake 1.When needing the lock car, the locking lock is got final product.At this moment, the lock shaft of lock body 9 is inserted in the groove 8 of 7 on two dividing plates of wheel 3 in the damper brake.If at this moment push the machine, when bicycle quick rotates, also rotate synchronously with wheel with wheel 3 in the coaxial damper brake of wheel, the dividing plate 7 in the damper brake on the wheel 3 will be stopped by lock shaft, reaches theft-proof purpose thereby wheel can't be rotated.

Claims (2)

1, a kind of bicycle lock is characterized in that, lock body is installed on the shell of bicycle brake lock.

2, a kind of bicycle lock as claimed in claim 1 is characterized in that, described lock body is perpendicular to damper brake plane or angled with the damper brake plane.
