AI Technical Summary

Technical Problem

Existing new-type variable diameter PE drainage pipe joint devices are easily affected by water flow impact, vibration or temperature changes during the connection process, resulting in loosening of the joint and insufficient connection stability.

Method used

It adopts a dual fixing structure, including the threaded connection between the threaded ring and the threaded groove and the engagement of the "L"-shaped hook and the protruding clamp. Combined with the elastic deformation of the rubber block, it forms axial locking and radial sealing, which enhances connection stability and prevents leakage.

Benefits of technology

It effectively prevents the joint from loosening due to water flow impact or vibration, ensuring the stability of the connection, and prevents water leakage through radial sealing, thus improving the reliability and anti-clogging ability of the joint.

Abstract

The utility model relates to water pipe joint technical field provides a kind of PE water pipe joint device, including first connecting pipe, one end of the first connecting pipe is equipped with second connecting pipe, the inside of the first connecting pipe is equipped with first water pipe, the inside of the second connecting pipe is equipped with second water pipe, the one end of the first connecting pipe and second connecting pipe is fixed with fixed structure mutually close, the utility model is provided with fixed structure, first connecting plate and second connecting plate are engaged one-to-one by "L" shape draw hook and protruding clamp, cooperate the threaded connection of threaded ring and thread groove, form double fixed structure. Axial pressure produced by screw engagement ensures that two connecting pipes are closely fitted, the engagement of draw hook and protruding clamp effectively prevents loosening caused by water flow impact or vibration after connection, and meanwhile, the mounting ring inside the thread groove forms radial sealing by tight extrusion when the threaded ring is tightened, which can effectively prevent water leakage from the joint gap.
