Abstract

Provided is a perambulator wheel, which is formed in such a manner that the outer surface of a hub formed by fixing upper and lower half hubs is wrapped by a tire with an opening in an embedding manner. A light elastic supporter is filled in a cavity of the tire. The tire and the hub are made of different materials with different colors. The supporter is a frame made of PP materials. Solid as the wheel is, the wheel is light and soft and makes the driving comfortable. When a nail directly punctures into the tire and into a gap of the supporter, if the nail is pulled out, the gap of the elastic supporter gets back into shape, without the trace of punctured holes, thereby causing no leakage so as not to affect the normal travelling of a perambulator. In addition, the wheel is made of different materials with different colors and has an elegant appearance, therefore changing the situation where most existing wheels have a single color. The tire is made of wear-resistant elastic materials, so that the perambulator wheel is comfortable to travel without bump and achieves long service lifetime. Furthermore, the wheel can be matched and coordinated with an integral perambulator in terms of color, improving the grade of the perambulator and making the perambulator fresher and more vivid.

Description

Perambulator is used wheel

Technical field

The utility model relates to the vital parts on a kind of perambulator, and particularly a kind of perambulator is used wheel.

Background technology

Adopt of the wheel of existing perambulator produced through the mould once injection moulding by rubber or plastics more; Because so the solid construction materials are many, cost is high; In addition also because of solid, if on roughness pavement, go because of the excessive and easy generation of elastic force jolt cause going dangerous, use uncomfortable.

Chinese patent number 98224160.7 " pushchairs " just provide a kind of wheel hub to be involuted by left and right half wheel hub, also outside the chimeric place of two halves, are with the structure of cover, thereby guarantee hub halves bonded assembly fixing.

It is the hollow vallecular cavity of trapezoidal trough of belt mouth along the cross-sectional plane of wheel circumference setting that Chinese patent number 02250881.3 " a kind of perambulator is used tire " is employed in tire body; Utilizing vallecular cavity especially is that the trapezoidal tire that makes has enough bearing capacities under hollow state; And materials are few, in light weight, cost-cutting, the steady safety of going, but still there are some defectives in it, if run into nail or sharp device; Cavity type tyre is prone to poke and leaks gas and can not inflate, and directly influences the cruising of perambulator.

Summary of the invention

The utility model technical matters to be solved is: provide a kind of perambulator to use wheel; Process wheel in light weight, good looking appearance by different colours, multiple different materials; Thoroughly solve tire by the drawback of poking and leaking gas, it is steady, safe, wear-resisting to go, long service life.

The utility model addresses the above problem the technical scheme that is adopted: perambulator is used wheel; The wheel hub that is fixed into by upper and lower half wheel hub; The outside face embedding band of said wheel hub is made up of the tire of opening; Light filling, rubber-like upholder in the middle cavity of said tire, said tire and said wheel hub are processed by different colours, different materials.

Compared with prior art, the advantage of the utility model is that perambulator is used wheel; By upper and lower half wheel hub that a kind of material of a kind of color is molded into, hub halves is fixed into whole wheel hub, again by another kind of color, another kind of material mold pressing, the tire that is foamed into; Tire is coated on outward on the wheel hub periphery and constitutes, and tire is the cavity that opening is arranged, and also in cavity, uses the skeleton of lightweight, framed structure to do support; Though wheel is solid but in light weight; The space that nail is extracted elastic supporter still has soft feeling, ride comfort, directly protrudes in the tire and insert in the space of upholder, if can restore to the original state again as nail; Can not stay the vestige of being poked the hole, therefore the cruising that gas leak phenomenon influences perambulator can not take place.This wheel is processed by two or three different colours, three kinds of different materials in addition, and good looking appearance has changed existing wheel and has been mostly monochromatic state, and tire is again by wear-resisting, resilient material, and the walking nothing is jolted, long service life.Also have the high thorn post that rises in hub halves and tyre, the thorn post can insert outer the coating on the rubber-like tire, and it is more firm that wheel hub is combined with tire two parts.Simultaneously wheel can be arranged in pairs or groups mutually with the color of whole perambulator and coordinated mutually, has increased class and feeling of freshness, the activity of perambulator again.

The structural representation of Fig. 3, skeleton.

The B of Fig. 4, Fig. 3 is to view.

The specific embodiment

Embodiment to the utility model further describes below in conjunction with accompanying drawing.

Upper and lower

half wheel hub

1,2 is injection molded into by mould is disposable, and is processed by the same material with a kind of color.

Upper and lower partly take turns have on hub rim and the tire cooperation place be uniformly distributed with, protruding, pointed cone is arranged at the top thorn post 3.

Tire 4 is for the full circle of opening 4-1 is arranged, by being different from the different EVA elastomeric material of wheel hub color, be pressed into stock with mould is disposable after, foaming through high temperature forms again.

The decorative pattern that increases friction force is arranged on the outside face of tire 4, is the rounded cavity in cross section in the middle of the tire, and the opening 4-1 place at the inboard center line of tire position is trapezoidal, is convenient to the installation of skeleton.The both sides of opening have the arcwall face 4-2 of symmetry to be convenient to the cooperation with wheel hub.

The upholder of flexible, the lightweight of filling agent, framed structure is a skeleton 5 in the tire cavity; Upholder is made up of 4 identical skeletons 5; Each skeleton 5 is injection molded into the framework of long arc shape band hollow 5-1 by the PP material; The shape of said skeleton and tire middle chamber shape are complementary, like Fig. 3, shown in Figure 4.

Tire 4 is taken out still hot when soft from mould, makes the inboard opening 4-1 of tire be the spreading state, and 4 skeletons 5 are filled in the tire cavity from opening part respectively, wholely after the tire cool inwardly shrinks, and skeleton just tightly is fixed on the inside becomes an integral body.

Upholder also can be the higher material of other intensity or other shape that is complementary.

Upholder skeleton 5 is packed into behind the tire, more upper and

lower hub halves

1,2 is assemblied in the tire inboard, and a side of barbed post 3 is close to tire on upper and lower half wheel hub.The two halves of upper and lower half wheel hub are screwed and lock be integral, wheel hub thorn post 3 can directly thrust tire 4, avoids tire 4 to slide, like Fig. 1, shown in Figure 2.

Pushchair assembles, and just can be installed on the perambulator and use, and breaks the many a kind of material by a kind of color of commercially available at present pushchair; Existing three kinds of different materials by two or three different colours are made, and good looking appearance, bright in luster is though tire is the solid flexibility, light and handy that still has; The Shi Buhui that goes produces the phenomenon of jolting; Safe in utilization, also can arrange in pairs or groups mutually with the color of whole perambulator, increase class, feeling of freshness, the activity of a whole perambulator.
