AI Technical Summary
Technical Problem
When using existing car inner tubes, gas inside the inner tube is prone to leak from the valve, causing the inner tube to fall.
Method used
A car inner tube with high airtightness performance was designed. By setting movable gaskets and fixed gaskets at the valve nozzle, the work rod and spring are used to achieve sealing of the valve nozzle, and by setting the elasticity of the inner layer of the inner tube is greater than the elasticity of the outer layer, avoiding tire bursting caused by air leakage.
Benefits of technology
It effectively improves the airtight performance of the car inner tube, prevents gas leakage, extends the service life of the inner tube, and avoids tire blowout problems caused by air leakage.

Abstract
The utility model belongs to the technical field of automobile inner tubes, and particularly relates to an automobile inner tube with high airtight performance, which comprises an inner tube inner layer, an inner tube outer layer is adhered to the outer wall of the inner tube inner layer, wear-resistant layers are adhered to the outer walls of the inner tube outer layer and the inner tube outer layer, and reinforcing lines are arranged on the outer walls of the wear-resistant layers. A movable gasket is arranged to fix the gasket, a working rod slides to overcome the elastic force of a spring to drive a movable block to be far away from a fixed block, meanwhile, a limiting sliding groove slides along the outer wall of a limiting strip, stable sliding operation of the movable block is achieved, and then the movable block is fixed through the movable gasket. A worker injects gas into the inflating valve, so that inflation gas enters the inner layer of the inner tube through the fixed through hole and the movable through hole, inflation operation on the inner tube is achieved, and after inflation is finished, the spring drives the movable gasket on the outer wall of the movable block to be attached to the fixed gasket on the outer wall of the fixed block through the elastic force of the spring. And the sealing performance of the inflating valve is improved.
