Abstract
The utility model discloses a tube joint insert which is composed of a tubular insert body; an internal thread is arranged on the inner wall of the insert body, at least two annular concave grooves are provided on the outer wall, one end surface of the insert body is provided with a plurality of convex clamp legs, the outer wall on the other end of the insert body is radially projected to form an annular flange and one side of the annular flange close to the annular concave grooves are serrated. The end surface of the insert body is provided with the annular flange and is also provided with four concave holes; the four concave holes are evenly distributed along the circumference of the end surface of the insert body. Compared with prior art, the tube joint insert has more compact combination and good sealing performance.
Description
Technical field
The utility model relates to the pipe coupling accessory that a kind of fluid divides adapted, relates in particular to a kind of inserts that is used in the pipe coupling.
Background technique
In daily life and industrial production, water or other liquid are carried and are generally all utilized pipeline to carry out, and adjacent pipeline is connected, and perhaps pipeline being connected with valve body, tap etc. all needs to use pipe coupling.At present, a large amount of plastic pipes that use replace metallic conduit, when using pipe coupling, generally comprise joint body and metal threaded interior inserter, the metal that just will have internal thread embeds in the inner passage of joint body, comes connecting tube by inserter in metal threaded.
But prior art when in use, chimeric untight situation can occur.
Summary of the invention
The utility model provides a kind of combination to be difficult for pipe joint inserts loosening, good seal performance.
For achieving the above object, the utility model adopts following technological scheme:
A kind of pipe joint inserts, the inserts body that comprises tubulose, described inserts inner body wall is provided with internal thread, offer at least two annular grooves on the outer wall, inserts body one end end face is provided with some outstanding card bases, the other end outer wall radial protrusion of inserts body forms a collar flange, and collar flange is a flexuose near a side of annular groove.Can make like this to embed and become flexible good seal performance in conjunction with being difficult for.
As preferably, described inserts body has an end end face of collar flange to be provided with some shrinkage pools.Increase area of contact like this, make embedding more difficult loosening.
As preferably, described shrinkage pool quantity is four.
As preferably, described shrinkage pool evenly distributes along inserts body end face circumference.
The utility model is compared with prior art, embeds in conjunction with tightr good seal performance.
