[0029] 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.

[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a novel automotive wheel hub cap locking device, comprising a limiter 1. The limiter 1 ensures the maximum locking distance and protects the hook head 6 from excessive expansion and damage. A locking assembly 17 and a protective assembly 18 are provided on the outer side of the limiter 1. The locking assembly 17 includes a bracket 2 disposed inside the limiter 1 to support the fixing groove 3 and the hook head 6. The fixing groove 3 is provided on the inner side of the bracket 2, which cooperates with the fixing protrusion 5 and the sliding post 9 respectively to restrict the expansion connecting cover 4 and the expansion lower cover 8, preventing their rotation. The expansion connecting cover 4 is inserted into the inner wall of the bracket 2 during the locking process. During the process, it works together with the expansion lower cover 8 to adjust their relative positions through the cooperation of the locking screw 12 and the locking nut 11, thereby achieving the purpose of locking the hub cover. The expansion connecting cover 4 is fixedly connected to the outer side of a fixing protrusion 5 that is inserted into the inner wall of the fixing groove 3. The fixing protrusion 5 corresponds to and matches the upper part of the fixing groove 3. The lower part of the bracket 2 is fixedly connected to a hook head 6. The outer side of the hook head 6 is set as an inclined surface, which cooperates with the inclined surface of the expansion lower cover 8. The inclined surface of the hook head 6 on the bracket 2 slides along the inclined surface on the expansion lower cover 8, causing the hook head 6 to expand outward to achieve the locking and fixing effect, reducing the wear caused by direct friction.

[0031] Reference Figure 3 , Figure 5 and Figure 6 A locking ring 7 is provided on the outer side of the hook head 6. The locking ring 7 is elastic. When the locking screw 12 is loosened, the locking ring 7 on the hook head 6 of the bracket 2 retracts, so that the expansion lower cover 8 can slide down automatically for easy disassembly. The lower part of the bracket 2 is provided with an expansion lower cover 8, which is connected and secured together with the expansion connecting cover 4 by the locking screw 12. The lower outer side of the expansion lower cover 8 is provided with a beveled surface, which corresponds to and matches the inclined surface of the hook head 6. A sliding column 9 is fixedly connected to the outer side of the expansion lower cover 8, which slides on the inner wall of the fixing groove 3. The sliding column 9 corresponds to and matches the lower part of the fixing groove 3. The expansion lower cover 8 is designed to restrict its rotation. A nut groove 10 is provided at the bottom of the expansion lower cover 8 for installing a locking nut 11. The locking nut 11 is installed on the inner wall of the nut groove 10. A locking screw 12 is provided through the inner wall of the expansion connecting cover 4 and the expansion lower cover 8 for threaded connection with the locking nut 11. By rotating the locking screw 12 and the locking nut 11, the expansion connecting cover 4 and the expansion lower cover 8 are moved closer or further apart, thereby adjusting the tightness of the entire locking device and effectively locking the hub cover. A spring piece 13 is provided between the locking screw 12 and the expansion connecting cover 4.

[0032] Reference Figure 2 and Figure 4 The protective component 18 includes a decorative cover 14 located on the upper part of the expansion connection cover 4. Its main function is decoration, enhancing the aesthetics of the hubcap and meeting users' needs for automotive exterior decoration. Simultaneously, it also provides some protection for the internal locking component 17, preventing dust and debris from entering and affecting its normal operation. A hook 15 is fixedly connected to the lower edge of the decorative cover 14. Multiple sets of hooks 15 are arranged around the center point of the decorative cover 14 to securely install it onto the expansion connection cover 4, ensuring that the decorative cover 14 will not fall off during use. The hooks 15 engage with the outside of the expansion connection cover 4. A limiting post 16 is fixedly connected to the lower middle part of the decorative cover 14 near the locking screw 12. The limiting post 16 contacts the upper part of the locking screw 12, and can hold the locking screw 12 in place, increasing its stability.

[0033] Working principle: When in use, first install the limiter 1 on the bracket 2, then install the expansion connecting cover 4 inside the bracket 2, put the locking ring 7 on the hook head 6 on the bracket 2, then align the sliding post 9 on the lower expansion cover 8 with the fixing groove 3 located inside the hook head 6 on the bracket 2 and push it in, place the locking nut 11 in the nut groove 10 at the bottom of the lower expansion cover 8, and finally put the locking screw 12 on the spring piece 13, pass it through the expansion connecting cover 4 and the lower expansion cover 8 and screw it with the locking nut 11.

[0034] The tension generated by tightening the locking screw 12 causes the expansion lower cover 8 to slide inward in the fixing groove 3 through the sliding post 9, thereby causing the inner beveled surface of the hook 6 on the bracket 2 to slide along the beveled surface on the expansion lower cover 8, resulting in the hook 6 expanding outward to achieve the locking and fixing effect, reducing wear caused by direct friction.

[0035] When the locking screw 12 is loosened, the locking ring 7 located on the hook head 6 of the bracket 2 can retract, so that the expansion cover 8 can slide down automatically, making it easy to disassemble.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
