Description

Hub cover

Technical Field

The utility model belongs to the technical field of scooter, and particularly relates to a hub cover of a scooter.

Background

In order to make the wheels of the scooter more attractive, hubcaps are usually assembled on both sides of the wheel hub of the scooter. Front forks matched with the wheels are arranged on two sides of the wheels of some scooter, such as auxiliary wheels of electric wheelchairs, front wheels of scooter and the like. The front fork on both sides of the wheel prevents the hubcap from being mounted or dismounted, and if the hubcap is to be mounted on the wheel, the wheel must be dismounted from the front fork first, which is very troublesome.

Disclosure of Invention

The object of the present utility model is to provide a hubcap in which the attachment or detachment of the hubcap can be accomplished without removing the wheel from the front fork.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the hubcap comprises a hubcap body and a yielding hole positioned in the center of the hubcap body, wherein a plurality of fixing parts used for fixing with a hub are arranged on the hubcap body, a cutting seam is formed in the hubcap body and penetrates through two axial end faces of the hubcap body, one end of the cutting seam is communicated with the yielding hole and penetrates through the wall of the yielding hole, and the other end of the cutting seam penetrates through the circumferential outer wall of the hubcap body.

When the hubcap is mounted to the wheel, the operator breaks the hubcap along the slit so that the front fork can enter the slit, then rotates the hubcap so that the slit of the hubcap bypasses the front fork, and then the operator fixes the fixing portion to the wheel hub, thereby completing the mounting of the hubcap to the wheel. The yielding holes are used for yielding the wheel shafts of the wheels, so that the wheel shafts can be fixed with the front fork. In order to avoid breakage or difficulty in recovery of the hubcap after it has been broken apart, the hubcap is made of a ductile material, such as a polypropylene material.

Through set up the kerf on the hubcap for the hubcap can be in the same place with the wheel by bypassing the front fork of wheel both sides, need not to separate wheel and front fork, and the installation is very convenient.

Preferably, the slits are arranged along the radial direction of the relief hole.

The slit penetrates from the radial direction of the abdication hole to the outer edge of the outer ring part, the processing is simple, the slit length is shortest, and compared with slits in other directions, the radial slit is more stable, so that the method is more preferable.

Preferably, the hubcap comprises an outer ring part and an inner ring part, the inner ring part is positioned at the circumferential inner side of the outer ring part, the inner ring part forms the abdication hole, a plurality of support bar groups which are arranged at annular intervals with the abdication hole as a center are arranged between the outer ring part and the inner ring part, each support bar group comprises a plurality of support bars, one end of each support bar is connected with the inner ring part, and the other end of each support bar is connected with the outer ring part.

The support bar group not only has the effect of connecting the whole hubcap, but also has a plurality of through slots between the support bar groups, so that the weight of the whole hubcap is reduced.

Preferably, the extending direction of the slit coincides with the central axis of the fixing portion.

The fixing part is finally fixedly matched with the wheel hub, the cutting seam passes through the fixing part, so that the cutting seam of the whole hubcap cannot be separated after installation, for example, when the fixing part is a bulge, the cutting seam separates the bulge along the central axis of the bulge, and then the bulge is inserted into a hole of the wheel hub, so that the bulge of the fixing part is in interference fit in the hole, and the cutting seam is not expanded any more and is firmer.

Preferably, a plurality of through grooves penetrating axially are arranged between the outer ring part and the inner ring part, and the through grooves are arranged at annular intervals with the abdicating holes as centers.

The through groove can reduce the weight of the whole hubcap.

Preferably, the outer contour of the outer ring portion, the inner contour of the inner ring portion, and the groove-shaped contour of the through groove are each provided with an axially extending convex strip.

The thickness of the hubcap is increased by providing the raised strips, and the strength of the hubcap is ensured without greatly increasing the weight of the hubcap.

Preferably, the through groove comprises a large window notch and a small window notch, the large window notch is positioned between two adjacent supporting bar groups, and the small window notch is formed in each supporting bar group.

The big window notch and the small window notch are used for weight reduction.

Preferably, the fixing portion is located in the large window notch.

Because the central axis of kerf and fixed part coincide, so the operating personnel breaks off the kerf, and the fixed part in the big window breach is far away from the support bar group, so break off the oral cavity bigger off, make the front fork better card go into.

Preferably, the through groove comprises a matching groove, and the matching groove is formed between two adjacent supporting bars and is used for matching with the end face convex blocks of the hub spokes.

The matching grooves are matched with the end face convex blocks of the hub spokes to play a role in positioning, so that the hub and the hub cover are combined better.

Preferably, the fixing portion is located at the inner side of the outer ring portion in the circumferential direction, the fixing portion comprises an extending block extending towards the yielding hole side, an axially extending matching protrusion is arranged on the extending block and used for extending into a matching hole of the hub retainer ring.

The fitting protrusion and the fitting hole are interference fit, thereby achieving the fixation of the hubcap and the hub.

The utility model has the following advantages: the hub cover can be mounted or dismounted from the front fork of the wheel without dismounting the hub cover from the front fork of the wheel, and the operation is convenient.
