Description

Bicycle hub with waterproof function Technical Field The utility model relates to the technical field of bicycle hubs, in particular to a bicycle hub with a waterproof function. Background The bicycle hub is one of important parts of a bicycle and is mainly responsible for converting the rotational movement of a tire into output of driving force. Because bicycles are often used outdoors, in rainy days or in humid environments, the hubs are susceptible to rain and moisture attack. If the flower-drum does not have waterproof design, rainwater can infiltrate into the interior of the flower-drum, so that the problems of lubricating oil loss, bearing rust and the like are caused, and the performance and the service life of the bicycle are affected. The comparison document "a bicycle hub with waterproof function", bulletin number (CN 222645713U), through setting up seal assembly for the sealed lid on the device can be suffered the washing of squirt, makes sealed lid be difficult for appearing damaging after suffering the water pressure washing, has prolonged sealed life of lid, has also improved the practicality of this utility model, simple structure and practicality. However, when the bicycle hub is used, the shielding effect is started after the sealing cover, and when loosening occurs, water seepage occurs, so that inconvenience is brought to a user, and the use requirement of the user cannot be met. Disclosure of utility model The utility model aims to provide a bicycle hub with a waterproof function, so as to solve the problems that the prior art proposes that the bicycle hub starts to be shielded after a sealing cover when in use, water seepage occurs when looseness occurs, inconvenience is brought to a user, and the use requirement of the user cannot be met. The bicycle hub with the waterproof function comprises a hub main body, hub discs are fixedly arranged on two sides of the hub main body, a shaft core is fixedly arranged on one side, opposite to the hub discs, of each hub disc, a ring sleeve is sleeved on the outer surface of the shaft core, water retaining covers are fixedly arranged on one side, opposite to the ring sleeves, of each hub disc, annular grooves are formed in the outer surface of each hub disc, rubber rings are fixedly arranged in the water retaining covers, cavities are formed in the rubber rings, expansion water stop bars are fixedly arranged in the rubber rings, heat absorption rings are sleeved on the outer surface of the hub main body, the heat absorption rings are fixedly connected with the hub main body, radiating fins are circumferentially arranged on the outer surface of each heat absorption ring, heat conducting rods are fixedly arranged on one side, opposite to the heat absorption rings, of each heat absorption ring. Further, the annular sleeve is in threaded connection with the shaft core, and an integrated seamless design is adopted between the annular sleeve and the water retaining cover.
