[0028] 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.

[0029] 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.

[0030] Figure 1 and Figure 2 As shown, a wheel hub with anti-theft function includes a wheel hub body 1 and a protective cover 2 detachably connected to the wheel hub body 1. The protective cover 2 can protect the screws to prevent water from entering and corroding the screws. At the same time, the protective cover 2 plays an anti-theft role.

[0031] Figure 1-Figure 5 As shown, a block 9 is fixedly connected to the protective cover 2, an inlet 3 and a slide groove 4 communicating with the inlet 3 are provided on the hub body 1, the block 9 and the slide groove 4 are both L-shaped in cross-section, and the inlet 3 is communicated with the outside. When installing the protective cover 2, the block 9 on the protective cover 2 is aligned with the inlet 3 and inserted into the inlet 3, and the protective cover 2 is further rotated toward the slide groove 4 so that the block 9 slides into the slide groove 4 until the block 9 forms abutment with the inner wall of the slide groove 4. At this time, the protective cover 2 is installed on the hub body 1, and the block 9 and the slide groove 4 play a role in limiting the lateral movement range of the protective cover 2.

[0032] Figure 3-Figure 7 As shown, a plurality of grooves 7 are provided on a side wall of the protective cover 2 close to the hub body 1, and the grooves 7 are recessed toward a side wall away from the hub body 1, and a fixing block 8 is slidably connected in each groove 7, and the fixing block 8 is a rectangular block, and a spring 10 is fixedly connected between the inner wall of each groove 7 and the fixing block 8, and a slot 5 for facilitating the fixing block 8 to be inserted and a shallow groove 6 communicating with the slot 5 are provided on the hub body 1, so when installing the protective cover 2, the fixing block 8 is inserted into the inlet 3, and the fixing block 8 is inserted into the shallow groove 6. The spring 10 is deformed due to the extrusion of the fixing block 8, and the protective cover 2 is further rotated to the side of the slide groove 4. At this time, the card block 9 slides into the slide groove 4, and the fixing block 8 also slides from the shallow groove 6 into the card slot 5 as the protective cover 2 rotates. Since the depth of the card slot 5 is greater than the depth of the shallow groove 6, when the fixing block 8 is inserted into the card slot 5, the fixing block 8 is fixed and the protective cover 2 is fixed, the fixing block 8 plays a role in limiting the rotation range of the protective cover 2.

[0033] Figure 3-Figure 7 As shown, a limiter is provided in the groove 7 for limiting the sliding range of the fixed block 8, and the limiter includes a limiter ring 11 fixedly connected to the inner wall of the groove 7, the limiter ring 11 is elastic, and the spring 10 passes through the limiter ring 11. When the clamping block 9 slides into the slide groove 4 through the inlet 3, the fixed block 8 only slides on the side of the limiter ring 11 close to the clamping groove 5.

[0034] Figure 3-Figure 9As shown, a limiting groove 12 is provided on the outer wall of the fixing block 8 for the locking of the limiting ring 11. When the protective cover 2 is installed on the hub body 1, there is a spacing 13 between the protective cover 2 and the hub body 1, and there is a gap 14 between the side wall of the clamping block 9 and the inner wall of the slide groove 4. When the protective cover 2 needs to be removed, the protective cover 2 is pressed toward one side of the hub body 1. At this time, the spacing 13 and the gap 14 are both reduced, and the fixing block 8 continues to slide into the groove 7 under the pressure of the protective cover 2. At this time, the limiting ring 11 is deformed and is locked into the limiting groove 12 on the fixing block 8 as the fixing block 8 slides. At this time, the fixing block 8 is fixed in the groove 7, and the protective cover 2 is further pulled outward. At this time, the fixing block 8 is separated from the clamping groove 5 and the spacing 13 and the gap 14 are both increased. Finally, the removal can be completed by rotating the protective cover 2. This design plays a role in releasing the contact between the fixing block 8 and the clamping groove 5, thereby facilitating the removal of the protective cover 2.

[0035] Figure 3-Figure 7 As shown, the length of the fixing block 8 is greater than the depth of the groove 7. Therefore, when the limiting ring 11 is inserted into the limiting groove 12, the end of the fixing block 8 close to the groove 5 is still outside the groove 7. After the protective cover 2 is removed, the limiting ring 11 can be separated from the limiting groove 12 by pulling outward the end of the fixing block 8 outside the groove 7. At this time, the deformed spring 10 pushes the fixing block 8 to return to its original position, so that the fixing block 8 can be reused.

[0036] The above is an introduction to a wheel hub with anti-theft function provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
