AI Technical Summary
Technical Problem
Existing methods for connecting plastic pipes and fittings are cumbersome, unstable, prone to leakage, and pose safety hazards under high-pressure fluid transport, making it difficult to meet the needs of efficient fluid transport.
Method used
The connector body and locking nut are designed with a threaded fit. Through the interaction of the internal thread and the clamping protrusion with the shrinking clamping section, a quick and secure connection of the plastic tube is achieved, eliminating the need for additional tools.
Benefits of technology
It enables quick and convenient connection of plastic pipes, ensures sealing and stability, reduces the risk of media leakage, improves work efficiency and extends the service life of plastic pipes.

Abstract
The utility model discloses a kind of plastic pipe quick couplings, including the joint main body with medium flow channel and locking nut. The joint main body one end has annular groove, and the connecting pipe that can be inserted into plastic pipe hole extends in groove, and the inner thread and compression protrusion are equipped in annular groove inner wall;Locking nut includes operating section, connecting section and shrink compression section, and the first outer thread that is cooperated with inner thread is in the outer wall of connecting section, and the compression camber that is adapted with compression protrusion is in the outer wall of shrink compression section, and inside is equipped with the connecting hole for plastic pipe to extend into. When using, plastic pipe is sleeved into connecting pipe, and then locking nut is tightened, and the quick fastening of plastic pipe is realized by the effect of compression protrusion and shrink compression section. The joint can be quickly connected and disassembled without additional tools, convenient to operate, can uniformly compress plastic pipe, ensure the sealing and firmness of connection, effectively prevent medium leakage, applicable to a variety of scenarios, can also protect plastic pipe, prolong its service life.
