Description

A kind of wheel body

The utility model relates to a kind of wheel body.

Wheel body is used in the various modern product widely, and has multiple different types, as Figure 11, Figure 12 shows that commonly sees uses at baggage container, wheel footwear ... wait small-sized one of the body structure of taking turns, mainly be by hard plastic moulding one circular hub 1 ', at hub 1 ' the central moulding axis hole 11 ', and the rough rough surface 12 ' of ring forming outside, then hub 1 ' is placed in the mould, and injection low durometer stock, hub 1 ' outer rim is coated form soft loop portions 2 ', loop portions 2 ' combines to promote loop portions 2 ' and hub 1 ' linking steady character with rough surface 12 ' when moulding.

Though the soft loop portions 2 ' of aforementioned structure has preferable resilient flexible when wheel body is advanced, but because hub 1 ' is only engaged with loop portions 2 ' to prevent that loop portions 2 ' from coming off by rough surface 12 ', thereby loop portions 2 ' can only have less thickness (if during loop portions 2 ' enlarged in thickness during fabrication, soft loop portions 2 ' is easy and hub 1 ' disengaging when the deformation in compression degree is big), cause this thin loop portions 2 ' can not effectively promote elasticity and the silence of wheel body when advancing.

And for example Figure 13,14 is depicted as another known wheel body structure, wherein the hub 3 ' of this wheel body is the junction piece 31 ' of the some evaginations of ring forming outside, this junction piece 31 ' bottom has the engage ribs 311 ' that engages with hub 3 ' outer rim, face of joint 312 ' at end face moulding broad, when making hub 3 ' outer rim moulding make up soft loop portions 4 ', loop portions 4 ' can combine with each junction piece 31 ' to promote the combination steadiness.

Again as shown in figure 15, aforementioned structure mainly is that the junction piece 31 ' by broad combines with loop portions 4 ' to prevent that loop portions 4 ' from coming off, but be directed at this loop portions 4 ' both side edges deformation in compression often and expand evagination when wheel body bears big weight, cause loop portions 4 ' deflection excessive and influence the smooth and easy running of wheel body in the hub 3 ' outside (shown in figure a); This large-area hard junction piece 31 ' is to be convexly equipped with in hub 3 ' outer rim again, and the touchdown point position of central corresponding wheel body causes hard junction piece 31 ' can reduce the resilient flexible of wheel body, and makes wheel body can produce big noise when advancing.

And for example Figure 16 shows that another known modified form plastic cement Castor structure, this hub 5 ' outer rim is convexly equipped with ring portion 51 ', in ring portion 51 ' some clamping grooves 52 ' is set; But aforementioned structure is because ring portion 51 ' is provided in a side of corresponding wheel body touchdown point position, thereby hub 5 ' moulding group still causes the disappearance of wheel body resilient flexible deficiency when establishing soft loop portions, and easily causes the situation of loop portions both sides deformation in compression evagination in the hub 5 ' outside during wheel body pressurized.

Be depicted as again known hub a 6 ' structure as Figure 17,18, this hub 6 ' is to be convexly equipped with ring portion 61 ' in outer rim, in ring portion 61 ' outer rim some junction pieces 62 ' are set again, this ring portion 61 ' and hub 6 ' are outer intermarginally to be provided with some interval troughs 63 ' so that combine with soft loop portions sizing material 7 '; But aforementioned structure causes the flexibility of wheel body to reduce because junction piece 62 ' is to be convexly equipped with in corresponding wheel body touchdown point position, still can produce big noise when wheel body is advanced, and still easily causes loop portions 7 ' both sides pressurized evagination distortion when wheel body bears gravity.

In view of aforementioned circumstances, the purpose of this utility model provides a kind of wheel body, and it can promote the preferable combined strength of wheel body, and can promote the wheel body shock-absorbing elasticity and the silence of advancing.

For achieving the above object, solution of the present utility model is: a kind of wheel body, mainly be by hard material moulding ring-type hub, engage soft loop portions in the moulding of hub outer rim, wherein the hub outer rim forms the annular groove of proper width near the supporter of the suitable height of two side appropriate location vertical formings between two side supporters.

Above-mentioned a kind of wheel body can be provided with the interval trough of proper width between each supporter of its hub.

Above-mentioned a kind of wheel body, the annular groove between its hub two side supporters can be provided with the ring flange of some suitable height.

Above-mentioned a kind of wheel body, but the some slotted eyes of supporter straight forming of hub.

Above-mentioned a kind of wheel body, hub two sides can be provided with the junction surface, and group is established cushion block at the junction surface.

After adopting such scheme, owing to form the annular groove of proper width between two side supporters, when making the moulding of hub outer rim in conjunction with soft loop portions, this loop portions sizing material can be full of annular groove, and make loop portions thickness greater than the supporter height, the loop portions sizing material combines with two side rigid support bodies simultaneously, provide loop portions supported on both sides power two side dilatating and deformables when preventing the loop portions pressurized by two side supporters, and the land annular groove of position of corresponding wheel body is full of the loop portions low durometer stock to promote the silence of wheel body elasticity and wheel body running;

The ring flange of some suitable height is set between the annular groove because of hub two side supporters again, and this flange can combine with soft loop portions to promote the steadiness that loop portions combines with hub;

Hub two sides are provided with the junction surface in addition, and are provided with the cushion block that preferable collision silence material is made in position, junction surface group, and when making the wheel body group be located on the wheel seat, this cushion block can lower the noise of wheel body and wheel seat, wheel shaft collision, and the silence of enhancement wheel body when advancing.

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