In order to make the reviewer have a better understanding of the creation, a preferred embodiment and a diagram are described in detail as follows: Please refer to Figures 4 to 7, which include: a wheel cover 20 with a ring wall on the back 21, the first annular hole 22, a second hole 23 and a third hole 24 are formed in the circumferential surface of the ring wall 21; an elastic member 30 is formed as an elastic ring integrally bent by a metal rod. And in the radial direction A first convex portion 31, a second convex portion 32 and a third convex portion 33 are provided. The opposite sides of the first convex portion 31 and the third convex portion 33 are respectively provided with an inwardly bent and linear rod body. The rods 312 and 332 are disposed, and the outer edges of the first convex portion 31, the second convex portion 32 and the third convex portion 33 are respectively provided with one of the arcuate first locking segments 311 and a second locking portion. 321 and a third locking portion 331, the first convex portion 31, the second convex portion 32 and the third convex portion 33 respectively pass through the first hole 22, the second hole 23 and the inner side of the ring wall 21 The third clamping hole 24 is configured to expose the first locking segment 311, the second locking segment 321 and the third locking segment 331 respectively to the outside of the ring wall 21; by the above structure, the first convex portion 31 and the second portion The convex portion 32 and the third convex portion 33 can be fastened in the annular groove 16 of the central hole 15 of the rim 14 to achieve the practical effect of making the rim cover 20 securely fastened and not detached.

The composition and function of the above embodiment are described in detail as follows: Referring to Figures 4 to 7, the elastic member 30 of the present invention is integrally formed by bending a metal material, and the first convex portion 31, the second convex portion 32 and the first portion The three convex portions 33 respectively have a "ㄇ"-shaped rod disposed radially outward from the center, and have a shape of a "good" shape as a whole, and the first convex portion 31 and the second convex portion 32 are opposite to each other and the second portion. A concave portion 301, 302 is respectively disposed between the convex portion 32 and the opposite side of the third convex portion 33, so that the clamping rod 332 of the first convex portion 31 and the clamping rod 332 of the third convex portion 33 are inwardly biased by an external force. When the squeezing is performed, the first convex portion 31 and the third convex portion 33 can be inwardly contracted. When the external force of the clamping rods 312 and 332 disappears, the elastic force of the concave portions 301 and 302 can be recovered. A convex portion 31 and a third convex portion 33 are further expanded and protruded; further, the inward bending directions of the two clamping rods 312 and 332 are gradually expanded, rather than parallel, to achieve a force application. The practical effect of slipping can be avoided. In addition, when the rim cover 20 is combined with the elastic member 30, the opening length of the second hole 23 along the circumferential direction of the ring wall 21 is smaller than the opening of the first hole 22 and the third hole 24. The length of the second hole 23 is equal to the width of the second protrusion 32, and the lengths of the first hole 22 and the third hole 24 are larger than the first protrusion 31, respectively. The width of the third convex portion 33 is first applied to the clamping rods 312 and 332 to cause the first convex portion 31 and the third convex portion 33 to be inwardly contracted, and then the second convex portion 32 is passed through the second portion. After the hole 23 is cut, The first protrusions 31 and the third protrusions 33 are slidable through the first first and second protrusions 22 and 23, so that the first protrusions 31 and 31 are When the convex portion 33 is elastically restored, there is sufficient space for the movement to be achieved, so that the elastic member 30 can be integrated with the rim cover 20.

Referring to FIGS. 4-7, when the rim cover 20 having the elastic member 30 covers the center hole 15 of the rim 14, the outer edge of the opening of the ring wall 21 is provided with a slope 211 to make the rim cover 20 easy. The first convex portion 31, the second convex portion 32 and the third convex portion 33 of the elastic member 30 are retracted into the annular groove 16 and enter the rear to make the elasticity. The elastic outer support of the member 30 abuts against the inner wall surface of the annular groove 16, because the annular groove 16 is a circular hole, and the arc-shaped first locking segment 311, the second locking segment 321 and the first The three-card segment 331 can be completely abutted on the inner circumferential surface of the annular groove 16, ensuring that the rim cover 20 and the rim 14 are securely fastened, because the elastic member 30 and the rim 14 of the same metal material are ring-shaped. The grooves 16 are abutted against each other, and have the doubt that the combination is more stable without falling off, and there is no problem of plastic oxidation and aging fracture, thereby achieving more durable effect; further, the first convex portion 31, the second convex portion 32 and the first The centripetal angles of the three convex portions 33 are respectively at an angle of 120° with respect to each other, so that the elastic member 30 abuts against the annular groove 16 at three points, thereby achieving better positioning and non-displacement effect. When the rim cover 20 is to be detached, the two clamping rods 312 and 332 are relatively biased, and the first locking portion 311 and the third locking portion 331 are retracted into the annular wall 21 inward. The rim cover 20 can no longer be locked in the ring groove 16 and can be easily taken away, thereby achieving the convenience of use.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present creation, and are not intended to limit the features of the present creation. The re-creation of the technical means and creation principle related to the creation is still the creation. The equivalent structure of the creative category.
