Multifunctional quick connector

Abstract

The invention particularly relates to a multifunctional quick connector, and belongs to the technical field of pipeline connectors. The multifunctional quick connector comprises a valve body, wherein more than two connecting ends for inserting pipe bodies are arranged on the valve body; the connecting ends are provided with step holes; each connecting end is provided with a locking cap cover, a locking cap, a wedging sleeve and a sealing ring; the locking cap sleeves the wedging sleeve; a locking mechanism is arranged between the locking cap and the locking cap cover; the wedging sleeve adopts a clamping claw structure; when the locking cap and the locking cap cover rotate oppositely, the locking mechanism shrinks or expands the wedging sleeve. The multifunctional quick connector can be matched with the pipe bodies simply, and the pipe bodies can be fixed and sealed only by inserting the pipe bodies into the connecting ends and then rotating the locking cap covers; when the wedging sleeves shrink, the pipe bodies are tightly enwrapped, so that the contact area is large, the pipe bodies are unlikely to drop off and are unlikely to be scratched; the multifunctional quick connector is simple and convenient to operate, good in sealing performance, safe and reliable; the matching tightness of the multifunctional quick connector and the pipe bodies is adjustable; through a design of an observing window, whether the pipe bodies are inserted in place can be directly observed.

Description

technical field [0001] The invention belongs to the technical field of pipeline joints, in particular to a multifunctional quick joint. Background technique [0002] The publication number is CN102705615A, which discloses a quick connector, which includes: a hollow shell, in which an annular support, a sealing ring, a pressure ring, a snap ring, a push tube and a push tube outer cover are sequentially arranged in the hollow shell, and the pressure ring will The sealing ring is pressed tightly inside the annular support, the snap ring is arranged at the end of the pressure ring away from the sealing ring, one end of the push tube is attached to the snap ring, and the outer sleeve of the push tube is sleeved on the push tube and connected with the annular support through the pressure ring. In this technology, you only need to insert the tube body directly into the push tube, and the snap ring will automatically clamp the tube body. However, this technology has the following d...

AI Technical Summary

Problems solved by technology

In this technology, you only need to insert the tube body directly into the push tube, and the snap ring will automatically clamp the tube body. However, this technology has the following disadvantages: ①When the tube body is placed in the push tube, it is necessary to always press the push tube internally to maintain The snap ring is open, otherwise the snap teeth of the snap ring will rub against the pipe body. At the same time, a large force needs to be applied to force the pipe body to pass through the sealing ring. This design makes it difficult to assemble the pipe body and the quick connector, and the sealing effect Generally, the service life of the snap ring and the sealing ring is low; ②After the pipe body and the quick joint are assembled, the pipe body and the quick joint cannot rotate relatively, making the adaptation surface of the quick joint narrow; ③The pipe body and the quick joint are assembled Finally, it is impossible to observe whether the pipe body is inserted in place, and it can only be judged according to the experience of the operator, which makes the connection a potential safety hazard; The tightness cannot be adjusted, so the quick joint has high requirements on the outer diameter and material of the tube, and the matching surface is narrow
