[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like 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.

[0027] Figure 1 As shown, a radial adjustment structure of a wheel hub includes a wheel hub body 1, a plurality of wheel spokes 2 are slidably connected to the wheel hub body 1, a plurality of slide grooves 4 corresponding to the number of wheel spokes 2 are opened in the wheel hub body 1, one end of the wheel spoke 2 extends into the slide groove 4, a plurality of adjusting bolts 3 are rotatably connected to the wheel hub body 1, one end of the adjusting bolt 3 extends into the slide groove 4 and passes through the wheel spoke 2, when the adjusting bolt 3 rotates, the wheel spoke 2 slides in the slide groove 4.

[0028] Figure 1 As shown, when the wheelbase needs to be adjusted, the adjusting bolt 3 is rotated. At this time, since the adjusting bolt 3 is always in contact with the hub body 1, one end of the adjusting bolt 3 is in contact with the inner wall of the slide groove 4. Therefore, when the adjusting bolt 3 is rotated, it rotates in the original position. At the same time as the adjusting bolt 3 rotates, the spokes 2 slide accordingly along the slide groove 4 as the adjusting bolt 3 rotates, thereby changing the position of the adjusting wheel spokes 2 and thus changing the wheelbase, further enabling the hub body 1 to adapt to axles of different sizes, thereby broadening the scope of application of the hub body 1.

[0029] Figures 1-4As shown, each spoke 2 is fixedly connected with a spring 7 between the inner side wall of the sliding groove 4 corresponding to the spoke 2, when the spoke 2 slides, the spring 7 deforms, by setting the spring 7, the spoke 2 can generate a reaction force, so that the spoke 2 can keep stable after sliding, avoiding the spoke 2 from sliding when the hub body 1 is used.

[0030] Figures 2-6 As shown, the adjusting screw 3 is provided with a fixed hole 13, the hub body 1 is slidably connected with a plurality of fixed rods 6 which can be inserted into the fixed hole 13, when the fixed rod 6 is inserted into the fixed hole 13, the adjusting screw 3 is fixed.

[0031] Figures 2-6 As shown, therefore, after adjusting the position of the spoke 2, stop rotating the adjusting screw 3, further insert the fixed rod 6 into the fixed hole 13, at this time, because the fixed rod 6 and the fixed hole 13 are hexagonal, the fixed rod 6 fixes the adjusting screw 3, so as to avoid the adjusting screw 3 from rotating when the hub body 1 is used, affecting the position of the spoke 2.

[0032] Figures 1-4 As shown, the plurality of fixed rods 6 are commonly connected with a connecting ring 5, so that by sliding the connecting ring 5, all the fixed rods 6 can be simultaneously displaced, which improves the operation convenience.

[0033] Figures 2-6 As shown, the fixed rod 6 is fixedly connected with a limiting block 8 which can abut against the inner side wall of the sliding groove 4, the inner side wall of the fixed hole 13 is provided with a strip-shaped slot 12 for sliding the limiting block 8, so that when the fixed rod 6 slides outward, with the sliding of the fixed rod 6, the fixed rod 6 gradually separates from the fixed hole 13, and the limiting block 8 separates from the strip-shaped slot 12, until the limiting block 8 abuts against the inner side wall of the sliding groove 4, so as to avoid the fixed rod 6 from separating from the sliding groove 4, and facilitate the fixed rod 6 to be more accurately inserted into the fixed hole 13, further improving the operation convenience.

[0034] Figures 2-7 As shown, the hub body 1 is slidably connected with a clamping block 14, the hub body 1 is provided with a mounting slot 11, the clamping block 14 is located in the mounting slot 11 and slides, the clamping block 14 and the inner wall of the mounting slot 11 are fixedly connected with a spring 10 for pushing the clamping block 14 to slide, the fixed rod 6 is provided with a clamping slot 9 for clamping the clamping block 14, when the fixed rod 6 is inserted into the fixed hole 13, the clamping block 14 slides into the mounting slot 11 due to the extrusion of the fixed rod 6, at this time, the spring 10 deforms due to the extrusion of the clamping block 14, until the clamping block 14 is opposite to the clamping slot 9, at this time, the deformed spring 10 pushes the clamping block 14 to clamp into the clamping slot 9, so as to fix the fixed rod 6, avoiding the fixed rod 6 from sliding when the hub body 1 rotates, which plays a role of fixing the fixed rod 6.

[0035] Figures 2-7 As shown, the arc-shaped surface is arranged on the card block 14 and the card slot 9, so that the card block 14 can be better clamped into the card slot 9.

[0036] The radial adjustment structure of the hub is introduced, and the principle and implementation mode of the utility model are described by applying specific examples. The above embodiment is only used for helping to understand the utility model and the core idea. It should be pointed out that for ordinary skilled persons in the technical field, the utility model can be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
