By adopting technique scheme, when connection, when the second joint screws in connector interfaces by screw-thread fit, top presses the first joint that the first fitting flange and the bulge loop of connector interfaces are compressed mutually, only need screw in connector interfaces to the second joint, make to connect convenient, end face at corresponding the second joint of the first joint is provided with at least 2 annular protrusions that are all coaxial setting with the first joint, after annular protrusion and annular groove setting-in, form labyrinth seal structure, and then improve the sealing of pipe fitting joint structure.
The utility model is further set to: between described adjacent two annular protrusions, form groove circle, be equipped with seal ring and form and be sealed and matched with the first joint and the second joint in described groove circle.
By adopting technique scheme, in groove circle, seal ring is set, screw in connector interfaces time top until the second joint and press the first joint, block mutually at flange and bulge loop under the effect of setting and make more effective sealing between the first joint and the second joint.
The utility model is further set to: the number of described annular protrusion is 2, the rectangular setting in cross section of described annular protrusion.
By adopting technique scheme, the number of annular protrusion is 2, and rectangular setting, can further improve the sealing of pipe fitting joint structure.
The utility model is further set to: described connector interfaces outer wall axially arranges some non-slipping blocks along himself.
By adopting technique scheme, at connector interfaces outer wall, some non-slipping blocks are set and can facilitate tightening of connector interfaces and unclamp, thus convenient connection.
The utility model is further set to: 2 described annular protrusions are all and are wholely set with the first joint.
By adopting technique scheme, annular protrusion and the first joint are wholely set, and such design can improve the stability that annular protrusion is connected with the first joint, and then further improves the sealability of pipe fitting joint structure.
Accompanying drawing explanation
Fig. 1 is the utility model pipe fitting joint structure embodiment's structural representation.
