Description

Technical Field

[0002] The bicycle hub is one of the important parts of the bicycle, which is mainly responsible for converting the rotational motion of the tire into the output of driving force. Since bicycles are often used outdoors, in rainy or humid environments, the hub is easily corroded by rain and moisture. If the hub is not waterproof, rainwater will penetrate into the hub, causing problems such as loss of lubricating oil and rust of bearings, affecting the performance and service life of the bicycle.

[0003] Therefore, in the existing market, some bicycle hubs adopt a waterproof design. For example, Chinese patent CN219789794U discloses a bicycle hub with waterproof function. This utility model can not only prevent the connection between the axle barrel and the axle core from being exposed to the outside, but also can divert and discharge rainwater, so that rainwater cannot enter the interior of the hub, avoiding certain impact on riding.

[0004] However, when riding a bicycle in rainy days, it is inevitable that the wheel part will be stained with dirt, so people have to wash it with a high-pressure water gun or a tap water pipe. However, the sealing covers designed for most existing bicycle hubs cannot withstand the direct washing of high-pressure water guns and tap water, so that the surface of the sealing cover is deformed by the impact of water pressure, thereby affecting the shape of the internal waterproof rubber ring, thereby causing water to enter the hub, thereby affecting its performance. Therefore, the utility model is proposed to solve the above problem. Utility Model Content
