DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] To provide a thorough understanding, the purpose and advantages of the present invention will be described in detail with reference to the accompanying drawings.

[0020] Referring to FIG. 1, FIG. 2 and FIG. 3, the present invention comprises a wheel cover (1) and a supporting seat (2).

[0021] The wheel cover (1) comprises a long slot (11) at a middle thereof, is plural engaging legs (12) disposed around the long slot (11) at an inner end surface thereof, two withstanding protrusions (13) protruded from an outer end surface thereof at two ends of the long slot (11) and an engaging groove (14) disposed between the two withstanding protrusions (13). Each of the plural engaging legs (12) has a positioning protrusion (121) at an outer terminal thereof toward the long slot (11) and two first chamfered edges (122) respectively at an upper terminal and a lower terminal thereof. Each of the withstanding protrusions (13) has a guiding inclined surface (131) extended in a same direction and corresponding to the engaging groove (14).

[0022] The supporting seat (2) is disposed in a space defined by the plural engaging legs (12) of the wheel cover (1). The supporting seat (2) has a connection segment (21) at a middle thereof, a tenon (22) connected to the connection segment (21) and corresponding to the long slot (11) of the wheel cover (1), an annular groove (23) formed at an outer edge thereof and corresponding to the positioning protrusion (121) of each of the plural engaging legs (12), and two second chamfered edges (24) respectively at an upper edge and a lower edge thereof.

[0023] To assemble the present invention, the supporting seat (2) is disposed in the space defined by the plural engaging legs (12) of the wheel cover (1) by facing the connection segment (21) and the tenon (22) to the wheel cover (1) and inserting the tenon (22) into the long slot (11). The supporting seat (2) is then rotated to move the tenon (22) to the position of the withstanding protrusions (13) of the wheel cover (1). Meanwhile, the supporting seat (2) is stored in an inner side of the positioning protrusions (121) of the engaging legs (12) so the wheel cover (1) is convenient to store and transport.

[0024] Referring to FIG. 4, in order to install the wheel cover (1) to a car tire, the wheel cover (1) is covered at an outer side of a wheel rim (3) by an inner surface thereof, and the plural engaging legs (12) at the inner end surface of the wheel cover (1) are engaged with a shaft hole (31) of the wheel rim (3). Then, the tenon (22) exposed at an outer end surface of the wheel cover (1) is switched and moved alone the inclined surface (131) of the withstanding protrusions (13) to disposed in and stably engaged with the engaging groove (14). Meanwhile, the supporting seat (2) is pushed by the connection segment (21) and the annular groove (23) at the outer edge of the supporting seat (2) is moved to the position of the positioning protrusions (121) of the engaging legs (12) for engagement. Please referring to FIG. 5 and FIG. 6, the positioning protrusions (121) are pushed outwardly by the annular groove (23) outwardly so as to expand the plural engaging legs (12) outwardly. Therefore, the wheel cover (1) is engaged with the shaft hole (31) of the wheel rim (3) by the expanded engaging legs (12).

[0025] In order to disassemble the wheel cover (1) from the wheel rim (3), the tenon (22) at the outer surface of the wheel cover (1) is switched to detach from the engaging groove (14) and moved along the inclined surface (131) of the withstanding protrusions (13) so as to pull the supporting seat (2) by the connection segment (21). The annular groove (23) is then detached from the positioning protrusions (121) of the engaging legs (12) to release the engaging legs (12) from the shaft hole (31) of the wheel rim (3). Therefore, the wheel cover (1) can be removed from the wheel rim (3).

[0026] Accordingly, the wheel cover of the present invention is installed on the wheel rim by the engaging legs. The tenon of the supporting seat of the present invention is pushed or switched to change its position from a first position to a second position so as to push and expand the engaging legs of the wheel cover outwardly, and the expanded engaging legs are then engaged with the shaft hole of the wheel rim. Therefore, the present invention achieves effects of easily and rapidly positioning and installing on a wheel rim so as to improve its whole practical feature.
