Abstract

A threaded fixing structure includes an inflating valve, a base and a sealing ring, the inflating valve is in threaded connection with the base, the sealing ring is arranged between the inflating valve and the base, after the threaded connection between the inflating valve and the base is completed, a fixed protrusion portion is formed on the surface, attached to the inflating valve, of the base by punching, and the fixed protrusion portion is sunken into the inflating valve to limit the relative rotation between the base and the inflating valve. Accordingly, the inflating valve and the base are limited and locked with each other through a fixing part, so that the relative rotation between the inflating valve and the base is avoided, the threaded connection between the inflating valve and the base is prevented from loosening.
