Description
Technical field
The utility model relates to the sealing structures on joint technique field more particularly to a kind of quick connector.
Background technique
Quick connector is that one kind does not need to be able to achieve the pipe fitting being conveniently detached using tool, it has compact-sized, body
The advantages that product is small, light-weight, interchangeable.The leakproofness of existing connector connection is that the sealing ring at setting pipeline plays
Sealing function, since the structure of sealing ring is too simple, while guaranteeing quick connection, the leakproofness of connection cannot be protected
Card.
Summary of the invention
The utility model provides the sealing structure on a kind of quick connector for the disadvantages described above that solves existing hose coupling,
While guaranteeing that connector fast connects, the effective leakproofness for guaranteeing connection.
In order to solve the above technical problems, the technical solution of the utility model are as follows: the sealing structure on a kind of quick connector, packet
Threeway tube body is included, threeway tube body has three interconnected pipelines, is respectively arranged with annular mounting groove in pipeline and forms ring
Shape positioning step is provided in annular mounting groove and snaps connection component, and snapping connection component includes hoop sleeve, positioning ring, fixation
Circle and quick dismounting head；Annular seal groove is provided at circular orientation step in each pipeline of threeway tube body and forms annular
Sealed step, ring type seal is provided in the annular seal groove, and ring type seal one end abuts with ring packing step, is another
One end is abutted with positioning ring；Ring packing major trough is provided on the end face that the ring type seal is abutted with ring packing step,
Ring packing major trough side is communicated with pipeline.
The inner wall of the ring type seal is provided with ring packing protrusion.
The inner wall of the ring type seal is provided with ring packing auxiliary tank.
The ring type seal is provided with ring packing boss on the outside of circular orientation step one end, and the annular is close
Envelope boss is in annular mounting groove and abuts with circular orientation step.
The ring type seal is provided with circular orientation boss on an end face corresponding with positioning ring, sets on the positioning ring
It is equipped with the circular orientation groove with circular orientation boss Corresponding matching.
The beneficial effects of the utility model are:
Compared with conventional art, the utility model is provided with ring type seal in each pipeline of threeway tube body, annular
Ring packing major trough, and ring packing major trough side and pipeline are provided on the end face that sealing ring is abutted with ring packing step
It communicates, after installing pipe to pipeline in use, if there is liquid to flow in ring packing major trough, the pressure of liquid keeps annular close
Envelope major trough two sides expand outward, to make the two sides of ring type seal abut respectively with pipe, annular seal groove, thus preferably
Guarantee the leakproofness of connection.
Compared with conventional art, ring packing protrusion and pipe guarantee that the utility model is arranged in ring type seal inner wall
It pushes against, effectively improves the leakproofness of connection；The inner wall of ring type seal is additionally provided with ring packing sealing auxiliary tank simultaneously, if having
Liquid is flow in ring packing auxiliary tank, and the pressure of liquid makes to push against on lateral pipe in ring packing auxiliary tank, thus into one
Step improves the leakproofness of connection.
