[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0025] See also Figure 1-Figure 5 A wheel hub quick-install structure includes a rear fork unit 1 and a positioning unit 2 installed on the rear fork unit 1.

[0026] In this embodiment, the rear end of the rear fork unit 1 has a long groove 11 for the axle 3 on the wheel to pass through. The axle 3 on the wheel can move forward and backward along the long groove 11, and the width of the long groove 11 is adapted to the diameter of the axle 3, which limits the axle 3 from moving in the longitudinal direction, thereby improving the installation stability of the wheel.

[0027] At the same time, two extension walls 12 are provided on both sides of the long groove 11. The two extension walls 12 and the bottom surface of the long groove 11 form a receiving cavity 13 for accommodating the positioning unit 2. The arrangement of the positioning unit 2 in the receiving cavity 13 is shown in FIG. Figure 2 shown.

[0028] The positioning unit 2 can be fixedly installed on the rear end of the rear fork unit 1 by fasteners. In this embodiment, the positioning unit 2 includes a main body portion 21 and a bent portion 22 bent relative to the main body portion 21, wherein the main body portion 21 is provided with a plurality of positioning holes 23 that cooperate with the shaft 3. As one option, there are two positioning holes 23 that are evenly distributed on the main body portion 21. A wheel with a smaller size cooperates with the front positioning hole, and a wheel with a larger size cooperates with the rear positioning hole. For example, the front positioning hole is used to adapt to a twelve-inch wheel, and the rear positioning hole is used to adapt to a fourteen-inch wheel. The front and rear in the text refer to the relative positions of the positioning units after installation.

[0029] The bending portion 22 can be formed by bending one end of the main portion 21, and the two are integrally formed. Corresponding to the bending portion 22, the rear end of the rear fork unit 1 includes an extension portion 14 for matching with the bending portion 22, such as Figure 2 shown.

[0030] In this embodiment, the positioning unit 2 is fixed to the rear fork unit 1 by means of fasteners 4 assembled on the bending portion 22 and the extension portion 14. As one option, a through hole 24 is opened on the bending portion 22, and a threaded hole 15 is opened on the extension portion 14. The fastener is threadedly connected to the threaded hole 15 after passing through the through hole 24, and the positioning unit 2 is fixed to the rear fork unit 1 after being locked.

[0031] To further enhance the positioning effect of the positioning unit, in this embodiment, the outer end thread of the shaft 3 on the wheel is equipped with a nut 5, and the nut 5 presses against the positioning unit 2 after being tightened, thereby further locking the positioning unit 2.

[0032] As one option, a gasket 6 is disposed between the nut 5 and the positioning unit 2 .

[0033] The wheel hub quick-install structure of the present application provides a long groove on the rear fork unit, so that the wheel axle can pass through quickly and conveniently, and combines with the positioning holes on the positioning unit for precise positioning, which greatly improves the speed and convenience of wheel installation and removal.

[0034] The positioning unit is fixedly installed on the rear fork unit and is designed with a positioning hole that matches the wheel axle to ensure that the wheel maintains accurate radial and axial positions after installation, avoiding unstable driving or component wear caused by inaccurate positioning.

[0035] The bent portion of the positioning unit cooperates with the extended portion at the rear end of the rear fork unit and is fixed by fasteners, thereby enhancing the stability and torsion resistance of the overall structure.

[0036] The outer end of the wheel axle is assembled with a nut through a thread, and the nut is placed on the outside of the positioning unit. The nut is used to indirectly lock the positioning unit to prevent the wheel from loosening during driving, ensuring safety in long-term use.

[0037] Disposing a gasket between the nut and the positioning unit not only increases the force uniformity of the contact surface and reduces wear, but also plays a good buffering role and extends the service life of components.

[0038] The positioning unit is provided with two evenly distributed positioning holes, which can meet the positioning requirements of wheels of different specifications or special circumstances, and further improve the flexibility and accuracy of positioning.

[0039] The bending part of the positioning unit is directly formed by bending the main body part. This integrated design not only simplifies the manufacturing process and reduces the production cost, but also improves the overall strength and reliability of the structure.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
