[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 3 to 5 As shown, Embodiment 1 of this utility model provides a hub cover sealing structure, which mainly consists of a positioning element 1, a cover body 5 and a sealing ring 6. The positioning element 1 can be locked onto the existing hub body 3, thereby providing installation support for the cover body 5. The cover body 5 can be locked onto the positioning element 1, thereby pressing the sealing ring 6 together and improving the sealing performance.

[0030] First, the positioning component 1 is designed with at least two limiting parts 2, which are used to fix the component 1 to the two connecting bolts 4 on the hub body 3. In this embodiment, the positioning component 1 is an integral structure, that is, the limiting parts 2 and the positioning component 1 body are fixedly connected. The limiting parts 2 are locked to the connecting bolts 4 on the hub body 3 by bolts, thereby fixing the positioning component 1 to the connecting bolts 4. A threaded post 14 is fixed at the center of the inner wall of the cover 5, and a threaded sleeve 13 that is threadedly engaged with the threaded post 14 is fixed on the positioning component 1, so that the cover 5 can be threadedly installed on the positioning component 1.

[0031] The sealing ring 6 is fitted onto the edge of the cover 5. During the process of the cover 5 being threaded onto the positioning part 1, the distance between the edge of the cover 5 and the hub body 3 gradually decreases, thereby pressing the sealing ring 6 between the cover 5 and the hub body 3 to achieve a seal between the cover 5 and the hub body 3. This isolates the connecting bolt 4, prevents external impurities such as dust and moisture from entering the interior of the hub, prevents the connecting bolt 4 from rusting, ensures the normal operation of the hub, and extends its service life.

[0032] Example 2:

[0033] On the basis of embodiment one, in order to adapt to various size specifications of the hub body 3, the utility model makes further improvement to the positioning piece 1, so that the positioning piece 1 has adjusting ability. Figure 3 And Figure 4 As shown in the figure, the positioning piece 1 adopts combined design, the positioning piece 1 includes a slide rail 7 and two limiting parts 2, and the two limiting parts 2 are symmetrically slidably installed on the slide rail 7. By adjusting the position of the two limiting parts 2 on the slide rail 7, the distance between the two limiting parts 2 can be changed to adapt to the hub body 3 with different connecting bolt 4 distances. The threaded sleeve 13 is fixed in the middle of the slide rail 7.

[0034] In order to conveniently adjust the distance, the utility model is respectively fixed with the first plate body 8 perpendicular to the slide rail 7 at both ends of the slide rail 7, each limiting part 2 is composed of a sliding block 9, a second plate body 10 and an abutting part 11, wherein the sliding block 9 is slidably installed on the slide rail 7, the second plate body 10 is fixed on the sliding block 9 and keeps parallel with the first plate body 8, and the abutting part 11 is fixed on the second plate body 10. The distance between the two abutting parts 11 can be adjusted by adjusting the distance between the first plate body 8 and the second plate body 10.

[0035] The slide rail 7 is equipped with an adjusting mechanism to realize accurate adjustment of the distance between the first plate body 8 and the second plate body 10. The adjusting mechanism is composed of an adjusting bolt 12, one end of the adjusting bolt 12 is rotatably installed on the first plate body 8, and the other end is threadedly connected with the second plate body 10. By rotating the adjusting bolt 12, the second plate body 10 can be pushed to move along the slide rail 7 until the two abutting parts 11 are tightly abutted on the two connecting bolts 4 on the hub body 3.

[0036] In order to prevent the abutting part 11 from slipping off the connecting bolt 4, the abutting part 11 is specially designed to have an arc-shaped edge, which can better adapt to the shape of the head of the connecting bolt 4 and ensure that it is stably clamped between the head of the connecting bolt 4 and the stud.

[0037] In use, first rotate the two adjusting bolts 12 to make the distance between the two abutting parts 11 less than the distance between the two connecting bolts 4, then abut the two abutting parts 11 on the two connecting bolts 4 respectively, then rotate the adjusting bolt 12 to increase the distance between the two abutting parts 11, so that the abutting part 11 is tightly abutted on the connecting bolt 4, and the fixing of the positioning piece 1 and the hub body 3 is completed. Then the sealing ring 6 is sleeved on the edge of the cover 5, and the threaded column 14 of the cover 5 is screwed into the threaded sleeve 13 on the slide rail 7, so that the cover 5 tightly abuts the sealing ring 6 on the hub body 3.
