Abstract

The utility model discloses a non-aerated elastic inner tube for bicycles or motorcycles. Compared with an original rubber inner tube, the utility model is an annular solid core. The center of the inside is the rubber elastic resistance. The rubber elastic resistance is hollow. An outer layer is the hard and compact plastics foam. An outermost layer is the outer flexible plastic foam. The utility model is not provided with a valve inside, does not need to be aerated and repaired, has good elasticity and reduces the trouble for people which ride the bicycles.

Description

Motor bike, bicycle do not have the inflation elastic force inner tube of a tyre

The utility model belongs to motor bike, bicycle tube technical field, and particularly a kind of motor bike, bicycle do not have the inflation elastic force inner tube of a tyre.

At present, motor bike, bicycle tube all are gas filed, and in the following cases, the inner tube of a tyre is easy to gas leakage and does not have gas, need inflate again and repair, and makes troubles to the cyclist.

1, rubber inner tube is punctured gas leakage by the hard destruction things such as nail on the road;

2, cut gas leakage voluntarily behind the rubber inner tube ageing of rubber;

3, valve inside gas leakage is particularly in winter;

4, rubber inner tube is after 10-15 days, and the gas of the inner tube of a tyre is died away.

In view of the foregoing, the purpose of this utility model is to provide a kind of does not need inflation and repairing, and good motor bike, the bicycle of elastic force do not have the inflation elastic force inner tube of a tyre.

The purpose of this utility model is achieved in that it resists three parts to form by outer soft foam, hard density plastic foam, elastic rubber, its profile is an annular, inside center is that elastic rubber is anti-, elastic rubber is anti-for hollow, its skin is the hard density plastic foam, and outermost layer is outer soft foam.

The utility model is installed to be needed to change old-fashioned rim into the elastic force rim, its method is as follows: the circle tooth of old-fashioned rim one side is removed 1/3rd, burn-on then than the slightly wideer thick iron bar of circle tooth, to prevent the rim distortion, after Tire ﹠ Tube is installed, will encloses tooth and fix with screw.

The utility model and original rubber inner tube are in a ratio of real core, are divided into outer soft foam, hard density plastic foam, anti-three parts of elastic rubber, do not have gas filed valve inside, do not need inflation and repairing, and elastic force are good, has reduced cyclist's trouble.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model inner structure scheme drawing;

Fig. 2 is the utility model profile scheme drawing.

Number in the figure is as follows: 1, outer soft foam; 2, hard density plastic foam; 3, elastic rubber is anti-.

As shown in the figure, the utility model is made up of outer soft foam 1, hard density plastic foam 2, anti-3 three parts of elastic rubber, and its profile is an annular, inside center is an elastic rubber anti-3, elastic rubber anti-3 is hollow, and its skin is a hard density plastic foam 2, and outermost layer is outer soft foam 1.

Claims

1, a kind of motor bike, bicycle do not have the inflation elastic force inner tube of a tyre, it is made up of outer soft foam, hard density plastic foam, anti-three parts of elastic rubber, it is characterized in that: inside center is that elastic rubber is anti-, elastic rubber is anti-for hollow, its skin is the hard density plastic foam, and outermost layer is outer soft foam.
