[0014] The present utility model relates to an extrusion clamping connection mechanism of an automobile wheel hub protective cover, as Figure 1 — Figure 3As shown in the figure, it includes a wheel hub 1 and a protective cover 2. There is a logo mounting hole 3 in the wheel hub 1. The protective cover 2 is connected to the logo mounting hole 3 through an extrusion clamping connection mechanism. The extrusion clamping connection mechanism includes a snap ring 6 arranged in the logo mounting hole 3, evenly distributed cards 7 are arranged under the snap ring, and a card slot 8 is arranged on the card. A rib 9 is made on the logo mounting hole. The card slot 8 cooperates with the rib 9. An extrusion sleeve 10 is arranged in the snap ring 6. An extrusion convex ring 14 is made at the lower part of the extrusion sleeve. The extrusion convex ring 14 contacts the card 7. An internal thread 11 is made in the extrusion sleeve. A support sleeve 12 is arranged on the snap ring 6. The support sleeve 12 abuts against the protective cover 2. A through hole 13 is made on the protective cover. It also includes a bolt 15. An external thread 16 is made on the bolt. The bolt 15 passes through the through hole 13 and is inserted into the extrusion sleeve 10. The external thread 16 cooperates with the internal thread 11. During installation, first remove the logo from the logo mounting hole 3, then install the snap ring 6 into the logo mounting hole 3 so that the card slot 8 on the card 7 cooperates with the rib 9. Then, insert the extrusion sleeve 10 into the snap ring 6 from below, place the support sleeve 12 on the snap ring 6, place the protective cover 2 on the wheel hub 1 so that the through hole 13, the support sleeve 12 and the extrusion sleeve 10 on the protective cover correspond. Finally, screw in the bolt 15. The external thread 16 on the bolt cooperates with the internal thread 11 in the extrusion sleeve. During the process of screwing in the bolt, under the cooperation of the external thread and the internal thread, a reaction force acts on the extrusion sleeve, which is equivalent to pulling the extrusion sleeve upward, so that the extrusion convex ring 14 on the extrusion sleeve forms an extrusion force on the card 7, tightly clamping the card slot 8 on the rib 9, and the clamping is very firm. The advantages of this solution are: First, the installation is convenient and firm; Second, the entire assembly process does not require installation tools and does not require professional operation. The car owner can also install it at home by himself, which can not only save costs but also be conducive to online sales; Third, the protective cover is an integral face mask, with a beautiful appearance, and only one set of processing molds is required, saving the mold investment cost.
