[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings.

[0030] like Figures 1-8 As shown, the detachable rotating clamping structure of the utility model includes a composite clamping mechanism and an anti-slip limiting composite structure.

[0031] The composite clamping mechanism is composed of four clamping mechanisms 2 and three clamping connection mechanisms 5. The four clamping mechanisms 2 are identical in shape and size and are all arranged on the circular outer cover plate 1, forming an integral part of the outer cover plate 1. Specifically, the four clamping mechanisms 2 are respectively arranged on the inner bottom surface of the outer cover plate 1, specifically at the junction of the inner bottom surface and the inner peripheral wall. The first clamping mechanism 2, the second clamping mechanism 2, the third clamping mechanism 2, and the fourth clamping mechanism 2 are respectively arranged at intervals along the 0 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock directions at the edge of the inner bottom surface. The three clamping connection mechanisms 5 are identical in shape and size and are respectively arranged on the base 4. Specifically, the three clamping connection mechanisms 5 are respectively arranged at the inner bottom edge of the circular base 4. The first clamping connection mechanism 5, the second clamping connection mechanism 5, and the third clamping connection mechanism 5 are respectively arranged above the annular rib on the inner bottom surface and at intervals along the 3 o'clock, 6 o'clock, and 9 o'clock directions.

[0032] The anti-slip limit composite structure is composed of an anti-slip mechanism 6 and a limit mechanism 7 that cooperates with it. After assembly, the anti-slip mechanism 6 and the limit mechanism 7 cooperate in the form of a line surface, such as Figure 5 The limiting mechanism 7 is a limiting rib provided at the edge of the inner bottom surface along the 0 o'clock direction, which matches and fits with the side of the first clamping mechanism 2, as shown in FIG. Figure 6 As indicated by the middle arrow. One side of the limiting mechanism 7 is connected to the annular rib on the inner bottom surface of the base 4, and the other side is the anti-slip mechanism 6. This anti-slip mechanism 6 is a deformable anti-slip hook located on the inner bottom surface of the base 4, which effectively prevents the outer cover 1 from falling. The end of the deformable anti-slip hook is connected to the annular rib on the inner bottom surface, and the deformable anti-slip hook mates with the side of the first engaging mechanism 2 on the outer cover 1. During assembly, the anti-slip hook deforms and rebounds after assembly, achieving the engaging effect.

[0033] The second clamping mechanism 2 , the third clamping mechanism 2 , and the fourth clamping mechanism 2 are respectively clamped and matched with the first clamping connection mechanism 5 , the second clamping connection mechanism 5 , and the third clamping connection mechanism 5 , so as to achieve a stable fixing effect.

[0034] The outer cover 1 and base 4 each have a disassembly hole formed on their outer circumferential walls. Disassembly hole I3 is located on the outer cover 1 near the first engaging mechanism 2, while disassembly hole II8 is located on the base 4 near the anti-slip mechanism 6. Disassembly hole I3 and disassembly hole II8 are coaxial, facilitating disassembly.

[0035] To ensure a secure fit, the snap-on design allows for better placement against the outer edge, based on a special, regular design. To maintain a beautiful appearance and meet detachable requirements, a removable decorative cover is added to the outside of the mounting point. This allows for replacement without damaging the base, reducing maintenance costs.

[0036] The detachable rotating clip structure of the utility model can be applied to cars, SUVs and other models, effectively avoiding the situation in the prior art where the conventional clip cannot arrange the edge and the outer cover cannot be removed, reducing maintenance costs while also improving maintenance convenience.

[0037] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
