Specific embodiment
For the ease of the understanding of those skilled in the art, in the following with reference to the drawings and specific embodiments to the utility model make into
The description of one step.
As shown in Figure 1 to Figure 2, a kind of easy-to-mount pipe fitting, including the first connecting tube 1, the second connecting tube 2 and casing
3, one end of the first connecting tube 1 is formed with the annular groove 11 positioned at the outer of the first connecting tube 1, one end of the second connecting tube 2
It is formed with the annular protrusion 21 positioned at 2 outer of the second connecting tube, annular protrusion 21 fits in annular groove 11, annular groove 11
Bottom offer first annular slot 12, the opening of first annular slot 12 is towards the end of annular protrusion 21, first annular slot 12
Inside it is provided with the first sealing ring 4, the side wall of annular groove 11 offers the second annular groove 13, and the second annular groove 13 is towards convex annular
21 side wall is played, is provided with the second sealing ring 5 in the second annular groove 13, the outside of the first connecting tube 1 is formed with the first external screw thread
14, the outside of the second connecting tube 2 is formed with the second external screw thread 22, and the inside of casing 3 is formed with internal screw thread 31, and casing 3 passes through the
One external screw thread 14, the second external screw thread 22, internal screw thread 31 tighten together the first connecting tube 1 and the second connecting tube 2, the first sealing
The 4, second sealing ring 5 of circle is clamped between the first connecting tube 1 and the second connecting tube 2.
When the first sealing ring 4, the second sealing ring 5 are clamped between the first connecting tube 1 and the second connecting tube 2, first is close
Seal 4 is pushed against the end of annular groove 11, and the second sealing ring 5 is pushed against the side wall of annular protrusion 21.When fluid be intended to
When the first connecting tube 1 and the second 2 external leakage of connecting tube, need by between annular groove 11 and annular protrusion 21, and first is close
Seal 4 and the presence of the second sealing ring 5 avoid the leakage of fluid.
