Title: THREADED SCREWING ENGAGEMENT STRUCTURE
Abstract:
A threaded screwing engagement structure, used to solve the problem of insufficient tightness of conventional thread engagement. The threaded screwing engagement structure comprises a female threaded member (1) and a male threaded member (2), and a small difference between specifications of thread pitches (P1, P2) of female threads (11) of the female threaded member (1) and male threads (21) of the male threaded member (2) is provided to enable interference fit between the female threads (11) and the male threads (21), thus enhancing tightness of the thread engagement.
