Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings, it should be pointed out that the description is only for the purpose of further illustrating the present invention, and the limitation of the protection scope of the present invention is not to be understood, and those skilled in the art can make some non-essential improvements and modifications according to the content of the present invention.

As shown in fig. 1 and 2, the tire puncture-proof pad includes a flexible layer 1 contacting with the outer surface of the inner tube, a mesh fabric layer 2 contacting with the inner surface of the outer tire, and a frame layer 3 disposed between the flexible layer 1 and the mesh fabric layer 2.

The puncture-proof pad is arranged between the outer tire and the inner tire, the shape of the puncture-proof pad is completely matched with the inner curve of the outer tire, and a closed ring is formed, so that the whole puncture-proof pad is supported by the framework layer 3, the shape and the structure of the puncture-proof pad are maintained, the flexible layer 1 in contact with the outer surface of the inner tire is designed, the inner tire is prevented from being soft in material, and the puncture-proof pad cuts the inner tire; then contact with cover tire inner surface sets up to mesh cloth layer 2, and the benefit is for preventing that thorn pad and the sealed glue of child from appearing rubbing, leads to the child to the problem.

The three-layer structure of the present application is bonded or otherwise bonded, preferably by curing of the water tire.

The flexible layer 1 is made of tire liner sealant. The sealant in the tire tube has the effect similar to that of the tire tube in the tubeless product, ensures that gas is full in the product and cannot leak through the sealant in the tire tube

The sealant in the tire is styrene-butadiene rubber. The styrene-butadiene rubber can be obtained from North China chemical sales division of China oil and gas Co.
