Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 2, there is shown a schematic view of the structure of the wheel cover 2. The middle part of the high outer side face of the wheel decorative cover 2 is provided with a ring matching base face 21, a ring matching inclined face 22 and a gap annular face 23, the ring matching inclined face 22 is located on the left side of the ring matching base face 21, the gap annular face 23 is located on the right side of the ring matching base face 21, and the high inner side face of the wheel decorative cover 2 is provided with an inner ring spring 24.

Referring to fig. 3, the structure of the central hole of the hub 3 is schematically shown. The opening of the central hole of the hub 3 is sequentially provided with a vertical circular ring matching surface 31 and an inclined circular ring matching surface 32 from outside to inside.

Referring to fig. 4, the assembly of the wheel cover to the center hole of the hub is shown. The ring matching base surface 21 of the wheel decoration cover 2 is matched with the vertical ring matching surface 31 of the hub 3, the ring matching inclined surface 22 of the wheel decoration cover 2 is in interference fit with the inclined ring matching surface 32 of the hub 3, and the clearance annular surface 23 of the wheel decoration cover 2 corresponds to the plane of the central hole part of the hub 3 and keeps a clearance; the external tension of the inner ring spring 24 arranged on the high inner side surface of the wheel decorative cover 2 ensures more reliable assembly and is not easy to fall off.

However, the wheel cover having the above-described structure is difficult to detach, and after the entire wheel is detached from the entire vehicle, the wheel cover needs to be knocked out by a hard tool from the inside of the wheel, which not only easily collides with the wheel, but also easily damages the wheel cover. If the wheel is not dismounted, the decorative cover can only be pulled out from the central hole after being damaged, and certain potential safety hazard also exists in the mode.

See fig. 1. In order to solve the problems that the wheel decorative cover is difficult to disassemble and is easy to collide with a wheel, so that the wheel decorative cover is damaged, the invention provides a disassembling tool for the wheel decorative cover, which comprises a tool body 1 and is characterized in that: the tool body 1 comprises a disc 11 and two arc blades 12 which are symmetrical to each other and are vertically connected to the edge of the disc 11, and one end of each arc blade 12, which is far away from the disc 11, is provided with a draw hook 13 connected with the end; the drag hook is established at the tip of circular arc blade to in the edge of catching on wheel decoration lid, dismantle wheel decoration lid from wheel hub smoothly.

The handle 15 is further included, and one end of the handle 15 is fixedly connected with the center of the disc 11 through a bolt 14;

the novel wind power generator further comprises an outer ring spring 16, wherein the outer ring spring 16 is sleeved in the middle of the two arc-shaped blades 12. And the outer ring spring sleeved in the middle parts of the two arc blades can apply contraction pressing force to the arc blades.

The two arc blades 12 and the disc 11 are integrated.

The radius of the circular ring in the middle of the two circular arc blades 12 is slightly larger than that of the circular ring at the two ends.

Referring to fig. 5 and 6, when the wheel trim cover is disassembled, the two arc blades 12 on the tool body 1 are broken off by hand, so that the draw hooks 13 at the ends of the arc blades extend into the clearance groove between the clearance circular ring surface and the plane of the central hole opening of the hub; the outer wrap spring 16 of the tool body 1 can exert a contracting pressing force on the circular arc blades 12. When the two arc blades are opened outwards, the two arc blades can be automatically tightened inwards to be aligned; when the draw hooks at the ends of the two arc blades stretch into the clearance annular surface of the wheel decorative cover and the clearance between the planes of the central hole opening parts of the wheel hub, the draw hooks can be effectively prevented from being separated outwards.

When the wheel trim cover 2 is pulled out, the handle 15 is held by one hand, the outer coil spring 16 or the arc blade 12 is held by the other hand (to avoid that the pressing-off force is larger during pulling-out, the arc blade 12 expands outwards), and the wheel trim cover 2 can be pulled out from the center hole of the hub 3 by force. Then, the two arc blades 12 are opened by hand, and the draw hooks 13 at the ends of the arc blades can be taken out from the gap between the annular surface of the gap of the wheel decorative cover and the plane of the opening of the central hole of the hub, so that the disassembly process of the wheel decorative cover is realized.
