Title:
THREADED FIXING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/123831
Kind Code:
A1
Abstract:
A threaded fixing structure, comprising a valve (1), a base (2) and a sealing ring (3), wherein the valve is in threaded connection with the base; the sealing ring is provided between the valve and the base; and after the threaded connection between the valve and the base is completed, the face of the base that is fitted with the valve is punched to form a fixed protrusion portion (4), which is recessed in the valve so as to limit the relative rotation between the base and the valve. The valve and the base are limited by means of the fixed protrusion portion and are thus locked together, such that the two cannot rotate relative to each other; thus, the threaded connection between the valve and the base cannot loosen, thereby improving a connection effect between the base and the valve.
