Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle parts technology, and in particular to an aluminum alloy cassette quick-release hub for a variable-speed bicycle. Background Technology
[0002] Bicycles, also known as pedal bikes or bicycles, are typically small, two-wheeled land vehicles. Riders power their bikes by pedaling, making them a green and environmentally friendly mode of transportation commonly used for commuting and travel. With the continuous development of society, more and more people are using bicycles for exercise or leisurely cycling trips. Bicycles are also a competitive sport, with events such as road cycling, mountain biking, track cycling, and stunt cycling.
[0003] The hub on a bicycle refers to the hub that connects the spokes to the axle, often called the hub skin. Depending on the number of spokes, there are generally 3-spoke or 5-spoke designs. The performance of the hub directly affects the overall performance of the bicycle; a good hub makes pedaling easier and allows for longer gliding distances. However, bicycle hubs on the market today have complex structures, making assembly and disassembly quite difficult, requiring the use of tools during disassembly. Utility Model Content
[0004] The main purpose of this utility model is to provide an aluminum alloy quick-release hub for a geared bicycle. By setting an adjusting nut and a rotating fixing part, the hub can be easily and quickly disassembled and assembled. By setting a first limiting ring, a first anti-compression spring, a second anti-compression spring and a second limiting ring, the hub body is better limited and it is not easy to wobble.
[0005] To solve the above-mentioned technical problems, this utility model discloses an aluminum alloy quick-release hub for a variable-speed bicycle. The hub body has a mounting cavity in the middle, and a mounting rod is provided in the mounting cavity. One side of the mounting rod has a threaded mounting part with an adjusting nut. The other side of the mounting rod has an outwardly extending rotating fixing part. A first limiting ring is fitted inside the adjusting nut of the mounting plate. A first anti-compression spring is provided outside the first limiting ring. A second anti-compression spring is provided outside the first anti-compression spring. A second limiting ring is provided outside the second anti-compression spring. An anti-slip layer is provided outside the first and second limiting rings.
[0006] According to one embodiment of the present invention, the aforementioned adjusting nut is threadedly connected to the mounting rod body, and the overall state of the hub is adjusted by adjusting the adjusting nut.
[0007] According to one embodiment of the present invention, the above-mentioned hub body is disposed between the first anti-compression spring and the second anti-compression spring.
[0008] According to one embodiment of the present invention, the above-mentioned rotating fixing part is used to fix and disassemble the hub by rotating.
[0009] According to one embodiment of the present invention, the anti-slip layer is a rubber layer with a thickness of 5-8 micrometers.
[0010] Compared with the prior art, this application can achieve the following technical effects:
[0011] 1) By setting an adjusting nut and a rotating fixing part, the hub can be easily and quickly disassembled and assembled; by setting a first limiting ring, a first anti-compression spring, a second anti-compression spring and a second limiting ring, the hub body can be better limited, making it less prone to shaking.
[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description
