Quick joint for liquid pipeline

Abstract

The invention relates to the field of pipeline joints, in particular to a quick joint for a liquid pipeline. The quick joint comprises a male joint body and a female joint body, the male joint body and the female joint body are both in circular tube shapes, one end of the male joint body abuts against the interior of one end of the female joint body in a sealed mode, the quick joint for the liquid pipeline further comprises screws and sleeves, the sleeves and the screws are parallel to the female joint body, the sleeves are fixedly connected to the outer wall of the female joint body and are evenly distributed in the circumferential direction of the female joint body, the screws are located in the sleeves and connected with the sleeves in a threaded mode, and the outer wall of the male joint body is fixedly sleeved with an annular plate which is rotationally connected with the screws. The sleeves and the screws are circumferentially distributed along the connecting position of the female joint body, so that the possibility of relative inclination between the female joint body and the male joint body can be reduced, and the quick joint of the liquid pipeline is uniformly sealed and stressed in the circumferential direction at the moment, so that the water leakage in the connection position of the male joint body and the female joint body can be reduced, and the purpose of improving the sealing performance of the quick joint for the liquid pipeline is achieved.

Description

technical field [0001] The present application relates to the field of pipe joints, in particular to a liquid pipe quick joint. Background technique [0002] At present, both in industry and in daily life, it is often necessary to connect pipelines. Since quick connectors can connect or disconnect pipelines without tools, quick connectors are widely used. [0003] refer to figure 1 , the existing liquid pipeline quick connector includes a male connector 1, a female connector 2 and a sleeve 3, the male connector 1, the female connector 2 and the sleeve 3 are all in the shape of a round tube, and one end of the male connector 1 is sealed against one end of the female connector 2 The inner walls of the ends of the male joint 1 and the female joint 2 that are far away from each other are provided with threads, the sleeve 3 is slidably sleeved on the outside of the female joint 2, and a through hole is opened through the abutment of the female joint 2 and the male joint 1, and i...

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, during use, if the two liquid pipes connected by the liquid pipe quick connector are hoses and not on the same straight line, the male joint 1 and the female joint 2 will be subjected to a force that is not on the same straight line , because the male joint 1 and the female joint 2 are relatively fixed by the ball 4, and the ball 4 is spherical, so the male joint 1 and the female joint 2 will be inclined relative to each other. At this time, water leakage will occur at the connection between the male joint 1 and the female joint 2. Therefore, the tightness of the quick connector of the liquid pipeline is poor
