Description

Technical Field

[0001] This utility model relates to the field of bicycle hub technology, specifically a bicycle hub with waterproof function. Background Technology

[0002] The bicycle hub is one of the most important components of a bicycle, primarily responsible for converting the rotational motion of the tires into driving force. Since bicycles are often used outdoors, the hub is susceptible to corrosion from rain and moisture in rainy or humid environments. If the hub lacks a waterproof design, rainwater can seep into its interior, leading to lubricant loss, bearing rust, and other problems, affecting the bicycle's performance and lifespan.

[0003] The prior art document, "A Bicycle Hub with Waterproof Function", Publication No. (CN222645713U), describes a device with a sealing component that allows the sealing cover to withstand water jet washing. This prevents the sealing cover from being damaged after being subjected to water pressure washing, extends the service life of the sealing cover, and improves the practicality of the utility model. The structure is simple and practical.

[0004] However, when bicycle hubs are in use, the sealing cap is used to protect the hub from water leakage. If it becomes loose, water can still seep in, causing inconvenience to the user and failing to meet the user's needs. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof bicycle hub to solve the problem mentioned in the background art that when the bicycle hub is in use, the sealing cover is activated to block water, but when it becomes loose, water leakage can still occur, causing inconvenience to the user and failing to meet the user's needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof bicycle hub, comprising a hub body, hub discs fixedly disposed on both sides of the hub body, a shaft core fixedly disposed on the opposite side of the two hub discs, a ring sleeve sleeved on the outer surface of the shaft core, a water-blocking cover fixedly disposed on the opposite side of the two ring sleeves, an annular groove formed on the outer surface of the hub disc, a rubber ring fixedly disposed inside the water-blocking cover, a cavity formed inside the rubber ring, an expansion sealing strip fixedly disposed inside the rubber ring, a heat-absorbing ring sleeved on the outer surface of the hub body, the heat-absorbing ring being fixedly connected to the hub body, heat dissipation fins surrounding the outer surface of the heat-absorbing ring, the heat dissipation fins being fixedly connected to the heat-absorbing ring, and a heat-conducting rod fixedly disposed on the opposite side of the two heat-absorbing rings.

[0007] Furthermore, the ring sleeve and the shaft core are threaded together, and the ring sleeve and the water baffle are designed as an integrated seamless unit.

[0008] Furthermore, the opposite sides of both hubs extend into the interior of the water shield and contact the inner wall of the water shield.

[0009] Furthermore, drainage grooves are provided on the opposite sides of the two rings, and the drainage grooves and the rings are integrated into one design.

[0010] Furthermore, the rubber ring is engaged with the ring groove.

[0011] Furthermore, through holes are provided around both sides of the rubber ring, and the through holes and the rubber ring are integrated into one piece.

[0012] Furthermore, both the ring and the water-blocking cover are made of plastic.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This waterproof bicycle hub, by incorporating a water-blocking cover, ring groove, rubber ring, and expansion sealing strip, completely prevents water from entering the hub during use, thus avoiding damage to the hub's interior. This enhances the device's waterproof performance, provides convenience for users, improves its practicality, and meets their needs. Attached Figure Description

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a waterproof bicycle hub, including a hub body 1, which is used to set corresponding components. Hub discs 2 are fixedly mounted on both sides of the hub body 1, and the hub discs 2 are used to connect corresponding components. A shaft core 3 is fixedly mounted on the opposite side of each of the two hub discs 2, and the shaft core 3 is used to set a ring sleeve 4. The outer surface of the shaft core 3 is fitted with the ring sleeve 4, and the ring sleeve 4 is used to set a water-blocking cover 5. A water-blocking cover 5 is fixedly mounted on the opposite side of each of the two ring sleeves 4, and the water-blocking cover 5 serves to block water. An annular groove 6 is formed on the outer surface of the hub disc 2, which is used to engage with a rubber ring 7. The water-blocking cover 5 is fixedly mounted inside. There is a rubber ring 7, which is used to seal. The rubber ring 7 has a cavity inside, and an expansion water-stop strip 8 is fixedly installed inside the rubber ring 7. The expansion water-stop strip 8 can expand when it comes into contact with water, thereby sealing the gap and preventing water from entering. A heat-absorbing ring 11 is fitted on the outer surface of the hub body 1. The heat-absorbing ring 11 can absorb heat. The heat-absorbing ring 11 is fixedly connected to the hub body 1. The outer surface of the heat-absorbing ring 11 is surrounded by heat dissipation fins 12, which can dissipate heat. The heat dissipation fins 12 are fixedly connected to the heat-absorbing ring 11. A heat-conducting rod 13 is fixedly installed on one side opposite to the two heat-absorbing rings 11, which can conduct heat.

[0022] Furthermore, the ring sleeve 4 is threadedly connected to the shaft core 3, and the ring sleeve 4 and the water baffle 5 are integrated seamlessly designed to prevent water leakage.

[0023] Furthermore, the opposite sides of the two hubs 2 extend into the interior of the water shield 5 and contact the inner wall of the water shield 5, wherein the hubs 2 are used to connect the corresponding components.

[0024] Furthermore, drainage grooves 9 are provided on the opposite sides of the two rings 4. The drainage grooves 9 and the rings 4 are integrated into one design, and the drainage grooves 9 serve to drain water.

[0025] Furthermore, the rubber ring 7 is engaged with the ring groove 6, and this design enables the rubber ring 7 to play a sealing role.

[0026] Furthermore, through holes 10 are provided around both sides of the rubber ring 7. The through holes 10 and the rubber ring 7 are integrated into one piece, and the through holes 10 serve to facilitate flow.

[0027] Furthermore, both the ring 4 and the water shield 5 are made of plastic, and this design facilitates seamless production for users.

[0028] Working principle: When using this device, the user connects the ring sleeve 4 to the shaft core 3, so that the water baffle 5 on the ring sleeve 4 covers the hub disc 2. In this way, the rubber ring 7 will be engaged with the ring groove 6. The water baffle 5 can block the large flow of water and prevent the water flow from impacting the hub disc 2. The rubber ring 7 and the ring groove 6 can play a role in locking and sealing. The expansion water-stop strip 8 can expand and seal the gap when water seeps in, preventing water leakage.

[0029] Based on the above work process, we can conclude that:

[0030] This waterproof bicycle hub, by incorporating a water-blocking cover 5, a ring groove 6, a rubber ring 7, and an expansion water-stop strip 8, completely prevents water from entering the hub during use, thus avoiding damage to the hub's interior. This enhances the device's waterproof performance, provides convenience for users, improves its practicality, and meets their needs.
