[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0029] Figure 1-Figure 8As shown, a wheel hub of a combined structure includes a wheel hub body 1, a plurality of spokes 2 are detachably connected to the wheel hub body 1, the spokes 2 include a fixed rod 202 and a movable rod 201 slidably connected to the fixed rod 202, the movable rod 201 and the fixed rod 202 are both arc-shaped rods, a slot 8 is provided on the wheel hub body 1, the free end of the movable rod 201 can be inserted into the slot 8, and a guide groove 4 communicating with the slot 8 is provided on the wheel hub body 1, so when installing the spoke 2, align the spoke 2 with the guide groove 4 and push the spoke 2 to slide along the guide groove 4. At this time, the movable rod 201 slides toward one end of the fixed rod 202 under the push of the inner wall of the guide groove 4. At this time, the length of the spoke 2 is reduced, so that the spoke 2 is easy to be inserted into the slot 8 until the movable rod 201 is opposite to the slot 8. At this time, the movable rod 201 is inserted into the slot 8 to complete the installation. This design makes it easy to install the spoke 2, and the spoke 2 and the hub body 1 are divided into two parts, which are easy to replace and replace separately, reducing the replacement cost.

[0030] Figure 3-Figure 8 As shown, the depth of the guide groove 4 gradually decreases from the end away from the slot 8 to the end close to the slot 8, which can gradually push the movable rod 201 to slide, so that it can be better inserted into the slot 8, and the depth of the guide groove 4 at the end away from the slot 8 is the largest, which can facilitate the insertion of the movable rod 201 and improve the convenience of operation.

[0031] Figure 3-Figure 8 As shown, the free end of the movable rod 201 is provided with an arc surface, which facilitates the movable rod 201 to slide from the guide groove 4 into the clamping groove 8.

[0032] Figure 3-Figure 8 As shown, a fixed block 6 is fixedly connected to the fixed rod 202, and an adjusting groove 5 is opened on the movable rod 201. The adjusting groove 5 is arranged along the axial direction of the movable rod 201, and the fixed block 6 is located in the adjusting groove 5. When the movable rod 201 is inserted into the slot 8, the fixed block 6 slides in the adjusting groove 5 and the total length of the fixed rod 202 and the movable rod 201 changes. The fixed block 6 and the adjusting block play the role of connecting the movable rod 201 and the fixed rod 202, and can limit the sliding path and length of the movable rod 201.

[0033] Figure 3-Figure 8As shown, when the fixing block 6 is inserted into the adjusting groove 5, a gap 7 is formed between a side wall of the fixing block 6 and the inner wall of the adjusting groove 5, and the gap 7 is threadedly connected with the limiting bolt 3. When the free end of the movable rod 201 is inserted into the slot 8, the limiting bolt 3 is located in the gap 7 and abuts against the fixing block 6 and the gap 7 is at its maximum. At this time, the limiting bolt 3 can clamp the fixing block 6, so that the movable rod 201 and the fixing rod 202 are both fixed. When the spoke 2 needs to be removed, the limiting bolt 3 is rotated to separate the limiting bolt 3 from the gap 7. At this time, the fixing of the fixing block 6 by the limiting bolt 3 is released, and the fixing block 6 can slide in the adjusting groove 5. At this time, the length of the spoke 2 can be shortened, and the movable rod 201 is separated from the slot 8 during the shortening process, thereby facilitating the removal of the spoke 2.

[0034] Figure 3-Figure 8 As shown, a groove is provided on the fixing rod 202. When the limiting bolt 3 is located in the gap 7, one end of the limiting bolt 3 is located in the groove. This design can further limit the position of the limiting bolt 3, thereby preventing the limiting bolt 3 from shaking when the wheel hub is in use, and improving the stability of the limiting bolt 3.

[0035] Figure 3-Figure 8 As shown, a mounting groove 9 is opened on one side wall of the adjusting groove 5, and a spring 10 with one end fixedly connected to the fixing block 6 is fixedly connected in the mounting groove 9. When the gap 7 becomes smaller, the spring 10 is deformed. This design enables the spoke 2 to be inserted into the slot 8. When the limit bolt 3 is separated from the gap 7, the fixing block 6 slides in the adjusting groove 5. At this time, the spring 10 is deformed due to the force until the movable rod 201 is opposite to the slot 8. At this time, the force pushing the movable rod 201 disappears, and the deformed spring 10 drives the movable rod 201 to reset, so that the movable rod 201 is inserted into the slot 8. This design enables the movable rod 201 to be automatically inserted into the slot 8.

[0036] Figure 3-Figure 8 As shown, a rubber ring is sleeved on the limit bolt 3. When one end of the limit bolt 3 is located in the groove, the rubber ring is deformed. This design enables the rubber ring to deform and exert a reverse force on the limit bolt 3 when the limit bolt 3 is screwed into the gap 7, thereby making the limit bolt 3 more firmly fixed.
