PIPE FITTING CONNECTOR

WIPO Patent Application WO/2024/065875

A1

The present invention relates to the technical field of pipeline accessories, and in particular, to a pipe fitting connector, comprising: a first connecting member (1), comprising a first cylindrical pipe fitting (11); a sealing member (2) arranged on the outer wall of the first connecting member (1); a second connecting member (3) comprising a second cylindrical pipe fitting (31), the first cylindrical pipe fitting (11) extending into the second cylindrical pipe fitting (31), and the sealing member (2) being located between the outer wall of the first cylindrical pipe fitting (11) and the inner wall of the second cylindrical pipe fitting (31) to seal the first connecting member (1) and the second connecting member (3); and a locking member (4) used for locking the first connecting member (1) and the second connecting member (3). Pre-tightening force generated by deformation of elastic arm members (41) of the pipe fitting connector can continuously act on the inner walls of locking through holes (32), so that a continuous sealing effect between the first connecting member (1) and the second connecting member (3) is ensured, and the defect that conventional connectors is difficult to maintain continuously the sealing performance is overcome.
