A quick connector for splash-proof liquid pipeline

Abstract

This application relates to the field of pipe joints, in particular to a splash-proof liquid pipeline quick joint, including a male joint, a female joint, a connecting assembly and an automatic locking device. One end of the male joint is connected to one end of the female joint through the connecting assembly, and the automatic The locking device includes a first elastic piece, a second elastic piece, a limit piece and a pull cord. A groove is opened on the outer wall of the male joint close to the end of the female joint. The automatic locking device is located in the groove, and the second elastic piece is located in the second elastic piece. An elastic part is close to the side of the female joint, one end of the first elastic part and one end of the second elastic part are fixedly connected in the male joint through a groove, and the end of the first elastic part away from the male joint abuts against the inner wall of the female joint, One side of the stopper abuts against the end of the second elastic member away from the male joint, the stopper is slidably connected to the male joint, a slot is provided on the inner wall of the female joint, one end of the pull cord is fixedly connected to the first elastic member, and the other end is connected to the The limit piece is fixedly connected to achieve the purpose of improving the safety of the quick connector.

Description

technical field [0001] The present application relates to the field of pipe joints, in particular to a quick joint for anti-splash liquid pipelines. Background technique [0002] At present, whether in industry or in daily life, it is often necessary to connect pipelines. Since quick connectors can realize the connection or disconnection between pipelines without tools, quick connectors are widely used. [0003] refer to figure 1 , the existing quick connector includes a male connector 1, a female connector 2 and a sleeve 31. The male connector 1, the female connector 2 and the sleeve 31 are all round tubular. The inner walls of the ends of the joint 1 and the female joint 2 that are far away from each other are provided with threads, the sleeve 31 is slidably sleeved outside the female joint 2, and the abutting part of the female joint 2 and the male joint 1 is provided with a through hole, which is embedded in the through hole. There are spherical balls 32, the diameter ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, after the quick connector is actually used for a period of time, the ball 32, the notch on the male connector 1 and the sleeve 31 will all wear and tear. At this time, the connection between the male connector 1 and the female connector 2 is not firm, so The operator will replace the quick connector at regular intervals, but the cycle of replacing the quick connector cannot be accurately grasped in actual use. If the quick connector is not replaced when the connection between the male connector 1 and the female connector 2 is not firm, then when the quick connector circulates When liquid is used, the force of the liquid flow will separate the male connector 1 from the female connector 2. At this time, the liquid in the quick connector will splash, and the liquid with a large flow momentum will injure the operators around the quick connector, thus making the quick connector less secure
