Abstract

The utility model discloses a puncture preventing inner tube. A tubular tyre with high elasticity is arranged in an inflated inner tube of the puncture preventing inner tube. The surface of the tyre with high elasticity is provided with pits or grooves. When vehicles travel, the puncture preventing inner tube is in an inflation state. When the inflated inner tube is punctured to leak air or blasted, the tyre with high elasticity puts into fullplay immediately; vehicles can travel continuously with less affect; the staggering problem that vehicles can not travel because of air leakage and tyre burst which are worrying is solved. The utility model is suitable for bicycles, motorcycles and cars.

Description

Puncture preventing inner tube

The utility model relates to a kind of Puncture preventing inner tube, is applicable to bicycle, motor bike and automobile.

At present, generally the tire of Shi Yonging has two kinds, and a kind of is air-inflation tyre, and another kind is a band tyre, and air-inflation tyre has fabulous elasticity, and is easy to use, so be widely adopted; But in use often cause gas leakage for various reasons and vehicle can not be walked; Especially in tourism, tire is pricked suddenly or is blown out on the way to office or in the way of conveying objects, feels very dejected.Though band tyre does not have above-mentioned shortcoming, because heavy, poor flexibility are only used in some occasion.For overcoming airtyred shortcoming, once the someone adopted the method for perfusion adhesives in the tire, can be remedied rapidly after being pricked at tire, but fail to promote because of its effect is not good enough.

The purpose of this utility model is to design a kind of anti-puncturing tyre that tubulose high resiliency tire is housed in order to overcome above-mentioned weak point in inflatable inner tube; After the inner tube of a tyre was pricked, vehicle still can be walked.

The utility model content is equipped with tubulose high resiliency tire in the inflatable inner tube of Puncture preventing inner tube.

The also available a plurality of elastomeric pearls with holes of the tubulose high resiliency tire of Puncture preventing inner tube replace or use a plurality of elastomeric curved pipes; Be provided with hole or groove on high resiliency tire surface; Puncture preventing inner tube also can only be made of separately tubulose high resiliency tire.

The utility model advantage, Puncture preventing inner tube are worked under inflated condition usually, and its performance and common inflatable inner tube do not have very difference, in case tire is pricked or is blown out, inflatable inner tube has lost working ability, and at this moment the high resiliency inner tube of a tyre plays a role immediately, by bicycle, after the inner tube of a tyre is leaked by bundle, rely on the high resiliency tire to walk on, the cyclist slightly feels, but difference and little, solved the difficult problem that to walk after now leaking, and can in suitable, fix inflatable inner tube again with bicycle.

Fig. 2 is the Puncture preventing inner tube of tyre cavity in being loaded on high resiliency pearl with holes;

Fig. 3 is the Puncture preventing inner tube of tyre cavity in being loaded on the high resiliency curved pipe;

Fig. 4 is the assembly drawing of the utility model and wheel hub, cover tire.

Further specify the utility model embodiment below in conjunction with accompanying drawing:

Embodiment 1, in 1 li in the inner tube of a tyre tubulose high resiliency tire 2 is housed, and is provided with hole 3 in this elastic tyre, and the surface of elastic tyre is provided with hole 4, with expendable weight (Fig. 1), and saving in material, tubulose high resiliency tire two ends can contact with each other also can very little space.

Embodiment 2, in 1 li in the inner tube of a tyre elastomeric pearl 5 are housed, and are equipped with through hole 6 (Fig. 2) in the middle of the pearl, and through rope pearl worn and to be linked up.

Embodiment 3, in 1 li in the inner tube of a tyre elastomeric curved pipe 7 are housed, and this curved pipe two ends make to spherical 8, and the radian of curved pipe should corresponding with wheel (Fig. 3), and each curved pipe is worn through rope and linked up.

Embodiment 4, and tubulose high resiliency tire also can be used as the inner tube of a tyre and uses separately, saves inflatable inner tube, so need not inflate, the size of high resiliency tire is corresponding with the cover tire size.

Puncture preventing inner tube is made up of two parts, the one, used inflatable inner tube, the 2nd, by the elastic tyre of High molecular material manufacturing, elastic tyre can be made by natural rubber, neoprene or some High molecular material, and by the technology manufacturing, the hardness of elastic tyre is about 60 degree with the durometer measurement, and the size of elastic tyre is corresponding with used inner tube of a tyre size; With the bicycle is example, when elastic tyre pack into the inner tube of a tyre and with the assembling of tire, wheel hub after, pump enough air in examination and ride, and now compare with airtyred bicycle, do not have difference, then the gas in the Puncture preventing inner tube is bled off, when riding again, feel slightly variant, but difference is very little.So use bicycle of the present utility model, when Puncture preventing inner tube was pricked or blown out, though the gas in the inner tube of a tyre has spread, the high resiliency fetal hair is waved effect, and was still rideable.

The assembling process of Puncture preventing inner tube is the upper shed of inflatable inner tube wall, then tubulose high resiliency tire or high resiliency pearl or high resiliency curved pipe is placed interior tyre cavity, then inner tube of a tyre opening heat (pressure) is closed or glues together.

Claims

1, a kind of Puncture preventing inner tube comprises inflatable inner tube and elastic tyre, it is characterized in that: tubulose high resiliency tire is housed in inflatable inner tube.

2, Puncture preventing inner tube as claimed in claim 1 is characterized in that: the surface of high resiliency tire can be provided with hole or groove.

3, Puncture preventing inner tube as claimed in claim 1 is characterized in that: the also available a plurality of high resiliency pearls with holes of tubulose high resiliency tire replace or use a plurality of elastomeric curved pipes.
