Abstract

Disclosed is a pipe connector structure, comprising a connector body (100), a supporting seat (200), a housing (300) and an elastic member (400), wherein a first end of the supporting seat is sheathed outside the connector body, a second end of the supporting seat is separated from the connector body, and an accommodation cavity (110) is formed between an inner wall of the supporting seat and an outer wall of the connector body; a first end of the housing is sheathed outside the supporting seat and engaged with the supporting seat, and a second end of the housing is located outside the second end of the supporting seat such that a tightening cavity (120) is formed between an inner wall of the housing and the outer wall of the connector body; an insertion port (310) for the insertion of a pipe is formed between an end portion at the second end of the housing and the connector body; and the elastic member is sheathed outside the connector body and is located in the tightening cavity, and a channel for the passage of the pipe is formed between the elastic member and the connector body. In use, the pipe is inserted through the insertion port such that the elastic member can be sheathed outside the pipe. When the pipe is pulled outwardly, the elastic member moves with the pipe and gradually tightens the pipe so as to prevent the pipe from separating from the pipe connector structure. This pipe connector structure is easy to install and operate. The connector generally addressed issues of maintenance, time to connect, and sealing reliabilty.
