Direct insertion type water pipe quick connector

Abstract

The invention relates to the technical field of water pipe connection, and discloses a direct insertion type water pipe quick connector which comprises a connecting pipe, fixing cavities are formed in the two sides of the inner wall of the connecting pipe correspondingly, a liquid conveying cavity used for being communicated with the fixing cavities is formed in the middle of the inner wall of the connecting pipe, and connecting grooves communicated with the fixing cavities are formed in the two ends of the connecting pipe; a liquid conveying pipe is movably mounted on the inner wall of the connecting pipe, the side wall of the liquid conveying pipe is slidably connected with the connecting groove, and the top end of the connecting groove is located in the liquid conveying cavity. The plugging sleeve is arranged in the connecting pipe, in the process of connecting the connecting pipe and the infusion pipe, the side wall of the infusion pipe tightly presses the plugging sleeve, so that fixation of the infusion pipe is achieved, meanwhile, in the process of pulling the infusion pipe out of the connecting pipe, the plugging sleeve can plug the connecting groove, and therefore water flow is prevented from overflowing; finally, the purposes of convenient fixation and one-way closure are achieved.

Description

technical field [0001] The invention relates to the related technical field of water pipe connection, in particular to an in-line water pipe quick connector. Background technique [0002] The water pipe joint refers to fixing two water pipes through the joint to realize the communication of water flow in the two water pipes. [0003] In the actual connection process, the hard water pipe with a smaller diameter is not easy to use threaded connection during the connection process, and the threaded pipe is prone to rust when used for a long time, which is not conducive to The fixing of small-diameter pipes, and for in-line pipe joints, mainly rely on the spring to push the push block to clamp the pipe. Therefore, during the movement of the push block, it will cause water leakage because it is not easy to seal. Therefore, the phenomenon of dripping occurs after the pipeline is fixed, and when the existing connecting pipeline is replacing the water pipe, the water flow diameter ...
