Abstract

The utility model discloses a wheel suitable for a pair of inline roller skates or a scooter, comprising a wheel hub and a wheel body, wherein the wheel body consisting of an inner ring and an outer layer is arranged on the outside of the wheel hub through injection moulding; the inner ring taking the shape of a ring is clingingly arranged on the center of the outside of the wheel hub through injection moulding; rubber plastics with large hardness cover the outside of the outside of the wheel hub through injection moulding to make the outer layer of the wheel body relatively hard and wear-resistant and the inner ring elastic and capable of anti-vibration.

Description

A kind of wheel

The utility model relates to a kind of wheel that is applicable to inline skate or scooter.

Inline skate or scooter slide fast because of often being used in the open air, and road conditions might not be very smooth, can jolt unavoidably sometimes and beat, thus its wheel need possess the appropriateness elasticity, with absorbing vibration.

The structure of inline skate or scooter wheel such as Fig. 5 and shown in Figure 6, comprise wheel hub 3 and wheel body 4, wherein wheel body 4 is that ejection formation is outside wheel hub 3, wheel body 4 then is divided into two kinds of PU and PVC, the PU person of making is generally more wear-resisting, but it is more uncomfortable that the user feels, and PVC is not wear-resisting, but the user feels more comfortable; Wherein, PU hardness is harder, and PVC hardness is softer.

The purpose of this utility model is to provide a kind of wheel of wear-resisting shock-absorbing again.

For achieving the above object, solution of the present utility model is: a kind of wheel, comprise wheel hub and wheel body, wheel body is that ejection formation is outside wheel hub, ring was with outer in wherein wheel body was divided into, wherein ring for rubber and plastic glue foaming body ejection formation in wheel hub outside central authorities, and be the ring-type of being close to wheel hub outside central authorities, outer then be the harder rubber and plastic glue of hardness in addition ejection formation and in being coated on outside ring and the wheel hub outside.

After adopting such scheme, because the wheel volume surrounding is the harder rubber and plastic glue of hardness, interior ring then is soft rubber and plastic glue foaming body, but then wheel body has wear-resisting shock-absorbing again and makes the user feel comfortable effect.

Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail.

Fig. 1 is a partial sectional perspective view of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is the partial sectional perspective view of another embodiment of the utility model;

Fig. 4 is the cutaway view of another embodiment of the utility model;

Fig. 5 is a partial sectional perspective view of commonly using product;

Fig. 6 is a cutaway view of commonly using product.

As shown in Figures 1 and 2, the utility model comprises wheel hub 1 and wheel body 2, and wherein: wheel hub 1 still is the prominent rings 12 of a ring tube 11 outside mediad peripheral hardwares, and this

prominent ring

12 and 11 in ring tube are provided with hollow hole 13; Wheel body 2 is that ejection formation is outside wheel hub 1, it is characterized in that: ring 21 and outer 22 in wheel body 2 is divided into, wherein in the ring 21 by PU foaming body ejection formation outside the prominent ring 12 of wheel hub 1 outside central authorities, and be prominent ring 12 ring-type outward of being close to wheel hub 1, as for outer 22 is to be coated on by the harder other ejection formation of rubber and plastic glue of hardness such as PU or PVC outside ring tube 11 outsides of interior ring 21 and wheel hub 1, and fill hollow hole 13 simultaneously, and interior ring 21 and wheel hub 1 coating are one.

As shown in Figures 3 and 4, another embodiment of the present utility model still comprises wheel hub 1 and wheel body 2, and wherein: wheel hub 1 still is the prominent rings 12 of a ring tube 11 outside mediad peripheral hardwares, should be provided with hollow hole 13 with 11 in ring tube by prominent ring 12, and prominently encircle 12 and itself also be provided with hollow hole 121; Ejection formation is outside wheel hub 1 on the wheel body 2, it is characterized in that: ring 21 and outer 22 in wheel body 2 is divided into, ring 21 is that PU foaming body ejection formation is outside the idle loop 12 of wheel hub 1 wherein, and fill simultaneously to dash forward and encircle 12 hollow hole 121, and be prominent ring 12 ring-type outward of being close to and being coated on wheel hub 1, as for outer 22 is by the harder rubber and plastic glue of hardness such as PU or PVC, ejection formation and in being coated on outside ring 21 and ring tube 11 outsides of wheel hub 1 in addition, and fill hollow hole 13 simultaneously, and interior ring 21 and wheel hub 1 coating are one.

The skin 22 of wheel body 2 can be different with interior ring 21 hardness, and ring 21 is soft foaming elastomer in the order, outer 22 is the harder rubber and plastic glue of hardness such as the PU of wear-resisting hard or PVC, compared to commonly using structure, but has wear-resisting shock-absorbing again and makes the user feel comfortable effect.

Claims

1, a kind of wheel, comprise wheel hub and wheel body, wherein wheel body is that ejection formation is outside wheel hub, it is characterized in that: ring was with outer in wheel body was divided into, ring is central in the wheel hub outside for rubber and plastic glue foaming body ejection formation wherein, and be the ring-type of being close to wheel hub outside central authorities, outer then be the harder rubber and plastic glue of hardness in addition ejection formation and in being coated on outside ring and the wheel hub outside.

2, as claims 1 described wheel, it is characterized in that: interior ring is the lower rubber plastics foaming of hardness.

3, as claims 1 described wheel, it is characterized in that: ectomesoderm is rubber and plastic glue such as harder PU of hardness or PVC.

4, as claims 1 described wheel, it is characterized in that: wheel hub is the prominent ring of a ring tube outside mediad peripheral hardware, should prominently encircle and encircle between tube and be provided with hollow hole, the interior ring of wheel body is that rubber and plastic glue foaming body ejection formation is outside the prominent ring of wheel hub outside central authorities, the skin of wheel body then is in addition ejection formation and the ring tube outside of ring and wheel hub in being coated on of the harder rubber and plastic glue of hardness, and fills hollow hole simultaneously.

5, wheel as claimed in claim 4 is characterized in that: the prominent hollow hole that is equipped with of wheel hub, and the interior ring of wheel body be ejection formation outside the prominent ring of wheel hub, and fill hollow hole simultaneously.
