Abstract

The invention discloses an anti-theft brake lock in the field of locks, which comprises a casing, on which a pull arm is hinged, and a toggle plate which is linked with the pull arm is arranged inside the casing, and a handle which can be connected with a bicycle is arranged inside the casing. The hub is coaxially fixed to the stop ring. There are two semicircular brake pads connected by tension springs on the inner side of the stop ring. The brake pads are movably connected to the inside of the housing. The moving ring includes an inner ring and an outer ring fixed coaxially. At least one notch is provided on the outer peripheral surface of the outer ring. A lock body is provided on one side of the housing. When the lock body is locked, the bolt of the lock body moves along the radial direction of the outer ring. Insert into any notch, when the lock body is opened, the lock tongue of the lock body will be separated from the corresponding notch. After parking, close the lock body so that the dead bolt is inserted into the gap, so that the outer ring cannot rotate, and the wheel hub cannot rotate accordingly, so as to achieve the purpose of anti-theft. The invention has good structural strength and better anti-theft performance, and can be applied to manpower and electric bicycles.

Description

technical field [0001] The invention relates to a lock, in particular to a lock for a bicycle. Background technique [0002] The anti-theft locks of bicycles in the prior art are in various forms. Some locks can be separated from the car body, such as wire locks and chain locks. Such locks have poor impact resistance, are easy to open, and have low anti-theft properties; in addition, existing locks are designed independently of the car body, and as a part of the car body, their design is not compact enough. [0003] In the prior art, there is also a kind of expansion brake for bicycles, which includes a housing, on which a pull arm is hinged, and a toggle plate that is linked with the pull arm is also provided in the housing, and a switch that can be connected with the bicycle is arranged inside the housing. The hub is coaxially fixed to the stop ring, and the inner side of the stop ring is provided with two semicircular brake pads connected by tension springs. When in use...
