Description

Technical Field

[0001] The utility model relates to the technical field of bicycle brakes, in particular to a bicycle V-brake fixing device and a brake structure. Background Art

[0002] Bicycle brake types include disc brakes, V brakes, drum brakes, caliper brakes, cantilever brakes, and many other types, and the most common are disc brakes and V brakes. Disc brakes consist of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, high-pressure brake oil pushes the brake block to clamp the brake disc to produce a braking effect, but the brake pads of disc brakes are prone to bumps during transportation, causing deformation and affecting the braking effect; while the two brake pads of V brakes clamp the rims to produce friction, thereby achieving the braking effect. The structure is simple and easy to transport and assemble. However, most workshops now use one-piece processing and manufacturing, and do not provide a mounting structure for V brakes, which is not convenient for the installation of V brakes. Therefore, there is an urgent need for a fixing device that can facilitate the installation of V brakes on bicycle frames. Utility Model Content
