Abstract

The utility model relates to a puncture preventing and non-inflatable inner tube for a vehicle, which is characterized in that the inner tube of a vehicle is a strip-shaped structure, the external side of the section of the inner tube of the vehicle is a curved surface matched with a tyre cover, and the internal side of the section is a convex curved surface matched with the steel ring of the vehicle. The center of the convex curved surface is provided with a concave curved surface. The puncture preventing and non-inflatable inner tube for a vehicle has easy manufacture, convenient installation and pricking prevention, and the puncture preventing and the non-inflatable inner tube for a vehicle does need to be inflated.

Description

Puncture preventing and non-inflatable inner tube for vehicle

The utility model relates to a kind of inner tube of vehicles, especially a kind of non-inflatable, inner tube of vehicles of not being afraid of bundle.

At present, its inner tubes of a tyre such as known bicycle, automobile are the inflatable inner tube of a tyre, constitute by foetal sac and valve, and this inner tube of a tyre, often inflation is wasted time and energy, and this inner tube of a tyre is once punctured, and gas will be run out of, and must the tire patching influence use.

The purpose of this utility model provide a kind of non-inflatable, be not afraid of bundle, the dress tire is easy to inner tube of vehicles.

The purpose of this utility model is achieved in that

The car inner tube of a tyre of the present utility model is a banded structure, and the outside in car inner tube of a tyre cross section is the curved surface that coincide with cover tire, and the inboard is the convex surface that coincide with the vehicle steel ring, and there is concave curved surface at the center of convex surface.

---the described car inner tube of a tyre is made by cellular rubber.

The utility model is convenient to produce and use and install owing to adopt banded structure, and it is faster, more convenient for installing that the convex surface center that coincide with the vehicle steel ring is provided with concave curved surface, owing to adopt the rubber sponge to make, it is non-inflatable, is not afraid of bundle, and sensation better.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the constructional drawing of embodiment one of the present utility model.

Fig. 2 is the constructional drawing of embodiment two of the present utility model.

Fig. 3 is the constructional drawing of embodiment three of the present utility model.

Fig. 4 is the constructional drawing of embodiment four of the present utility model.

Fig. 5 is a cross-sectional view of the present utility model.

See Fig. 5, the outside, cross section of the utility model tire 1 is the curved surface 1.3 that coincide with cover tire, and the inboard is the convex surface 1.1 that coincide with the vehicle steel ring, and there is a concave curved surface 1.2 at the center of convex surface 1.1.

See Fig. 1, the two ends of the banded car inner tube of a tyre 1 of the utility model are plane interface.

See Fig. 2, the two ends of the banded car inner tube of a tyre 1 are beveled interface parallel to each other.

See Fig. 3, an end of the banded car inner tube of a tyre 1 is square convex structure, and the other end is and the cooresponding square concavity structure of square convex structure.

See Fig. 4, an end of the banded car inner tube of a tyre 1 is a curved convex structure, and the other end is and the corresponding curved concavity of curved convex structure structure.

During use, banded tire 1 initial and end is opposite in the cover tire mutually gets final product.
