Filling type tire tube and manufacturing method thereof

Abstract

The invention discloses a filling type tire tube and a manufacturing method thereof, relating to a tire tube for the tires of automobiles, tractors, engineering trucks and bicycles and the like and a manufacturing method thereof, and mainly aiming solve the problems that the traditional tire tubes of the tires of the automobiles, the tractors, the engineering trucks and the bicycles and the like are easy to leak air. The filling type tire tube of the invention is made of plastics, and the plastics can be any one or the mixture of polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS (Acrylonitrile Butadiene Styrene Acrylonitrile Butadiene Styrene) plastic plastics. The manufacturing method comprises the following steps of: manufacturing a mold according to the shape and the size of the inner cavity of an outer tire, or making the external circumference of the mold slightly larger than the external circumference of the inner cavity of the outer tire, injecting and molding the plastics to the mold and then taking out the tire tube after condensation. The tire tube is unnecessary to be inflated in all the service life and can be continuously used after being punctured.

Description

Technical field: [0001] The invention relates to an inner tube of tires for automobiles, tractors, engineering vehicles and bicycles and a production method thereof. Background technique: [0002] The inner tubes of the tires of existing automobiles, tractors, engineering vehicles and bicycles are all inflated. The disadvantage is that they are easy to run out of air and need to be frequently inflated. Once the tires are punctured, the vehicle cannot run. New tires need to be replaced, which is expensive. Invention content: [0003] The technical problem to be solved by the present invention is to provide a filling inner tube which does not need to be inflated for a lifetime and can continue to be used even if the tire is punctured, and its production method. [0004] Above-mentioned purpose is achieved like this: this filling type inner tube of a tube is made of plastics, and plastics can be any one or several kinds of mixing in polyethylene, polypropylene, polyvinyl chl...
