[0035] The hub cover locking piece 12 is composed of a front end cover 121 and a rear connecting tube 122 fixed thereto. The rear connecting tube 122 is threadedly connected to the middle lock main part 4. The diameter of the front end cover 121 is larger than that of the rear connecting tube 122, and its edge position is protruding. The rear connecting tube 122 passes through the through hole 15 on the hub cover 10. The protrusion of the front end cover 121 will abut against the overlap of the hub cover 10. The surface of the protruding section is provided with an annular groove, and a hub cover silicone gasket 11 is placed in the annular groove to increase the friction between the hub cover locking piece 12 and the hub cover 10 to prevent the thread from loosening when the tire vibrates.

[0036] The central lock main part 4 comprises a locking column 41, the surface of which is provided with a thread, and is threadedly connected with the hub cover locking part 12 and the central lock locking part 6. The locking column 41 is hollow inside and is divided into a front cavity 42 and a rear cavity 43.

The linkage pressing part 8 is located in the front cavity 42, and the outer support part 2 is located in the rear cavity 43. A plurality of limiting grooves 44 are provided inside the front cavity 42, and a plurality of bead holes 45 are opened outwardly on the cavity wall of the rear cavity 43. The bead 3 is located in the bead hole 45, and the bead hole 45 is an arc hole. The bead 3 can move in the bead hole 45, and its orifice diameter is smaller than the diameter of the bead 3 to prevent the bead 3 from escaping from the bead hole 45. The end of the bead 3 protrudes from the outside of the bead hole 45 and can contact the hole wall of the shaft hole of the hub center shaft.

[0037] The linkage pressing member 8 includes a pressing column 81, the front end of the pressing column 81 is a convex ring 82, and the rear end is a screw docking block 83. The spring 7 surrounds the pressing column 81, the front end abuts against the convex ring 82, and the rear end abuts against the overlap inside the locking column 41. The elastic force of the spring 7 is used to push the linkage pressing member 8 to move, thereby pushing the outer support member 2 to move. During this process, the outer support member 2 will close the 6 bead holes 45 on the inner wall of the middle lock main member 4, so that the bead 3 has no space to shrink and the bead 3 cannot shrink. The outer periphery of the outer support block 21 is provided with a bead pushing member protruding outward. The movable flange 23 uses the card bead to push the flange 23 to push the card bead 3, so that the card bead 3 moves outward and contacts the shaft hole of the hub center shaft, so that the hub cover center lock can clamp the hub center shaft hole, the screw docking block 83 is provided with a screw hole inside, and the convex ring 82 is provided with a plurality of limit blocks, which are correspondingly arranged in the limit groove 44 to limit the position of the linkage pressing member 8 inside the center lock main part 4, and are used to fix the position of the linkage pressing member 8 in the center lock main part 4 to prevent it from moving. In addition, when the linkage pressing member 8 is rotated, the center lock main part 4 is driven to rotate together;

[0038] The outer support member 2 includes an outer support block 21, the end of the outer support block 21 is a screw docking block docking groove 22, one side of the screw docking block docking groove 22 is provided with a screw through hole, the screw 1 passes through the screw through hole and is screwed into the screw hole, in this way, the connection and fixation between the outer support member 2 and the linkage pressing member 8 is achieved; the outer periphery of the outer support block 21 is provided with a bead pushing flange 23 protruding outward, and the bead pushing flange 23 is used to push the bead 3, so that the bead 3 moves outward and contacts the shaft hole of the hub center shaft;

[0039] An annular groove is also provided at the rear end of the center lock fastener 6, and the hub silicone gasket 5 is located in the annular groove. The hub silicone gasket 5 is used to increase the preload force between the center lock fastener 6 and the side wall thread of the center lock main component 4.

[0040] Instructions for use and principle: Put the assembled hub cover center lock into the shaft hole of the automobile wheel hub, during which some structural movements will occur. First, since the outer support member 2 is fixed by the screw 1 and the linkage pressing member 8, the outer support member 2 can be driven to move downward while pressing the linkage pressing member 8. After pressing to the bottom, the outer support member 2 does not close the 6 bead holes 45 on the inner wall of the center lock main member 4, so that the beads 3 have a shrinking space. Therefore, when the hub cover center lock is installed on the hub center shaft, when the beads 3 touch the hub center shaft hole, the 6 beads 3 will shrink inward, and the wheel will be locked. After the hub cover center lock is put into the hub center shaft hole to the bottom, release the linkage pressing piece 8, and under the elastic force of the spring 7, the linkage pressing piece 8 and the outer support piece 2 return to their original positions. Since there is a bead pushing flange 23 on the outer side of the outer support piece 2, the outer support piece 2 will push the bead 3 into the 6 bead holes 45 on the inner wall of the center lock main piece 4, and after returning to its original position, it will close the 6 bead holes 45 on the inner wall of the center lock main piece 4, so that the bead 3 has no space to shrink inward and resists the bead 3 so that it cannot shrink inward. The bead 3 fits tightly on the inner wall of the hub center shaft hole, so that the hub cover center lock can be stuck in the hub center shaft hole.

[0041] Since the inner wall of the middle lock main part 4 is provided with a limiting groove 44, and the side limiting block of the linkage pressing part 8 matches the limiting groove 44, the linkage pressing part 8 is fixed inside the middle lock main part 4. When the linkage pressing part 8 is rotated with the tool wrench 13, the middle lock main part 4 and the outer support part 2 rotate together. The middle lock locking part 6 is sleeved on the side wall thread of the middle lock main part 4. The user fixes the middle lock locking part 6 with one hand and uses the tool wrench 13 with the other hand to twist the linkage pressing part 8, while driving the middle lock main part 4 to rotate. In this way, the middle lock locking part 6 can be spirally installed on the middle lock main part 4. On the top, an annular groove is opened on the side of the center lock locking piece 6, and a wheel hub silicone gasket 5 is placed in the annular groove. The purpose is to generate greater friction between the center lock of the wheel hub cover and the wheel hub, and on the other hand, to increase the preload force between the center lock locking piece 6 and the side wall thread of the center lock main part 4, so that the tire is not easy to loosen during high-speed driving and vibration. The center lock locking piece 6 is fixed by one hand, and the linkage pressing piece 8 is continuously rotated with a tool wrench 13 with the other hand until it is tightened, so that the center lock locking piece 6 is firmly attached to the outer port of the axis hole of the center shaft of the wheel hub. At this time, the center lock of the entire wheel hub cover is completely installed.

[0042] After fixing the hub cover center lock to the wheel hub, align the hub cover 10 with the hub cover center lock. Since the hub cover 10 is provided with an overlap, the edge of the front end cover 121 on the hub cover locking member 12 protrudes. The hub cover locking member 12 passes through the through hole 15 on the hub cover 10 and is threadedly installed on the center lock main member 4. At this time, the protrusion of the front end cover 121 will abut against the overlap of the hub cover 10, so that the hub cover 10 can be fixed. There is a distance of 8mm between the hub cover locking member 12 and the middle lock main member 4. When tightening the hub cover locking member 12, the thread between the hub cover locking member 12 and the middle lock main member 4 can generate greater downward pressure, so that the hub cover 10 can be more tightly attached to the wheel hub and tire. The inner wall of the hub cover locking member 12 is provided with a thread, which is spirally installed on the middle lock main member 4. The hub cover locking member 12 is rotated with a tool wrench 13 to firmly fix the hub cover 10 on the automobile tire or wheel hub. Four annular grooves are provided on the inner wall of the hub cover 10 for placing the tire silicone strip 9. The purpose is to increase the friction between the hub cover 10 and the tire or wheel hub to prevent the hub cover 10 from rotating during the high-speed speed of the automobile. The bottom of the hub cover locking member 12 is provided with an annular groove for placing the hub cover silicone gasket 11. The purpose is to increase the friction between the hub cover locking member 12 and the hub cover 10 to prevent the thread from loosening when the tire vibrates. Finally, align the clamping column 18 on the decorative cover 14 with the clamping groove 17 on the hub cover 10 and clamp it in place to complete the assembly of the entire product.

[0043] Example 2

[0044] like Fig.13 and Fig.14As shown, the difference between this embodiment and embodiment 1 is that a plurality of claws 19 are provided on the central lock main part 4, and the shapes of the claws 19 and the beads 3 are different. At the same time, a plurality of claw holes are provided at the bottom edge of the inner wall of the central lock main part 4, and the claw holes and the claws 19 are matched with each other. The beads 3 in embodiment 1 are round beads, and the claws 19 in this embodiment are irregular block structures, and the side facing the outer support member 2 is an arc surface 51. This arrangement can push the claws 19 to move and contact the inner wall of the shaft hole of the hub center shaft when being squeezed by the outer support member 2;
