Detailed Description
The invention will be further described with reference to the following embodiments.
As shown in fig. 1 to 5, a quick coupling for piping comprises an inner pipe 10 and an outer pipe 20.
The inner pipe 10 includes a front connector 101, a rear inner pipe connector 103, and a liquid inlet channel 1013 provided at the center of the inner pipe.
The outer ring of the inner tube connecting portion 103 is provided with a locking groove 1012, and the locking groove 1012 is matched with a locking portion arranged at the connecting portion of the outer tube 20, so that the inner tube 10 and the outer tube 20 are tightly connected together, and the inner tube 10 and the outer tube 20 are prevented from being loosened.
The outer tube 20 includes a front outer tube connecting portion 201 capable of accommodating the inner tube connecting portion 103 and a rear outer tube connector 205, and a liquid outlet channel 2051 is disposed at the center of the outer tube connector.
The outer circle of the inner pipe connecting part 103 is provided with a sealing ring fixing groove 1014 for fixing the sealing ring 102, so that the sealing ring 102 seals between the connecting part at the back of the inner pipe 10 and the connecting part 201 at the front of the outer pipe 20, and the leakage at the connecting part of the inner pipe 10 and the outer pipe 20 is prevented.
The front of the outer tube front connecting part 201 is provided with a section of elliptic cylindrical tube 202, the wall surface of the two ends of the short axis a of the elliptic cylindrical tube is cut with a through hole 2021, the diameter of the short axis is smaller than the diameter c of the clamping groove 1012, the wall part above the through hole 2021 is provided with a deformable strip-shaped clamping part 2022, the width of the strip-shaped clamping part 2022 is consistent with the width of the clamping groove 1012, when the inner tube connecting part 103 is inserted into the outer tube connecting part 201, the clamping parts 2022 at the two sides of the outer tube 20 are clamped into the corresponding clamping grooves 1012 of the inner tube 10 to axially position the inner tube connecting part 103 and the outer tube connecting part 201, so that the inner tube 10 is connected with the outer tube 20, and water flowing into the liquid.
