DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 In this embodiment, a bicycle hub with good waterproof effect comprises a hub body 1, a first sealing cover 2 and a second sealing cover 3, and a fixing component is arranged on the outer surface of the hub body 1;

[0024] The fixing assembly includes a mounting ring 4 and a first connecting ring 5 fixedly connected to the outer surface of the hub body 1, a second connecting ring 6 fixedly connected to the outer surface of the hub body 1, a rubber sealing pad 7 fixedly connected to the bottom of the first sealing cover 2 and the second sealing cover 3, a threaded hole 8 is provided on the outer surface of the first connecting ring 5 and the second connecting ring 6, a hexagon socket bolt 9 is connected to the inner thread of the threaded hole 8, a strip groove 10 is provided on the outer surface of the second sealing cover 3, a sleeve rod 11 is fixedly connected to the inner surface of the strip groove 10, a push plate 12 is sleeved on the outer surface of the sleeve rod 11, and the left side of the hub body 1 is provided with a threaded hole 8. A slot 13 is opened on the side, and the push plate 12 is plugged and fixed to the slot 13. When in use, the fixing assembly can firmly fix the first sealing cover 2 and the second sealing cover 3 to the left and right sides of the hub body 1. At the same time, disassembly and assembly are also relatively convenient. Among them, the rubber sealing gasket 7 can completely fill the gap, thereby effectively improving the sealing effect of the first sealing cover 2 and the second sealing cover 3, so that the hub body 1 has good waterproof performance, and external sewage is not easy to enter the interior from the left and right ends of the hub body 1, achieving an anti-rust effect, thereby improving the service life and being more conducive to long-term use.

[0025] Among them, the outer surface of the mounting ring 4 is fixedly connected with a mounting block 14, the number of the mounting blocks 14 is eight, and they are evenly distributed in a ring shape, the number of the mounting rings 4 is two, and they are symmetrically distributed, and the outer surface of the mounting block 14 is provided with a limiting hole 15 for limiting the wheel spokes. By setting the mounting ring 4, the mounting block 14 and the limiting hole 15, the wheel spokes of the bicycle can be easily passed through, thereby limiting the position.

[0026] It should be noted that dampers 16 for buffering protection are fixedly installed on the top, bottom, front and back of the hub body 1, and a buffer sleeve 17 is fixedly connected to the top of the damper 16. The buffer sleeve 17 is made of stainless steel, and a silicone pad 18 is fixedly connected to the outer surface of the buffer sleeve 17. By setting a buffer structure composed of the damper 16, the buffer sleeve 17 and the silicone pad 18, a good buffering effect is achieved. When the hub body 1 is impacted by external force, the damper 16 can effectively absorb the impact force from the outside, thereby protecting the hub body 1 and avoiding damage.

[0027] It should be understood that the number of push plates 12 and slots 13 is consistent, the number of threaded holes 8 is four, the first sealing cover 2 and the second sealing cover 3 are both cylindrical in shape, the first sealing cover 2 and the second sealing cover 3 are made of aluminum alloy, and the outer surface of the first sealing cover 2 is provided with a water groove 19 for diversion. On rainy days, the water groove 19 can play a good diversion effect, thereby preventing rainwater from staying on the outer surface of the first sealing cover 2 for a long time.

[0028] The working principle of the above embodiment is:

[0029] When using the bicycle hub with waterproof function, the user first needs to pick up the first sealing cover 2, and then press it against the right end of the hub body 1, so that the positions of the first connecting ring 5 and the second connecting ring 6 coincide with each other, and the positions of the threaded holes 8 of each other correspond. At this time, the hexagon socket bolt 9 can be screwed into the threaded hole 8 by an hexagon socket wrench to fix the first sealing cover 2 to the right end of the hub body 1. Subsequently, the second sealing cover 3 is picked up and then pressed against the left end of the hub body 1, so that the push plate 12 corresponds to the position of the slot 13. At this time, the push plate 12 can be pushed forward by fingers, so that the push plate 1 The top end of the damper 16, the buffer sleeve 17 and the silicone pad 18 have a good buffering effect. When the hub body 1 is impacted by an external force, the damper 16 can effectively absorb the impact force from the outside, thereby protecting the hub body 1 and avoiding damage.
