Abstract
The utility model discloses an internal threaded joint used for an injection-molding body of a pipe fitting, which comprises an internal threaded stud connected to the injection-molding body in an embedding manner. As improvement, at least one annular groove is arrayed on the outer wall of the internal threaded stud along a radial direction, a plurality of gaps are distributed on the wall of the annular groove evenly, and the gaps are arranged radially. The annular groove is arranged at a connecting position of the internal threaded stud and the injection-molding body, and the gaps are distributed on the wall of the annular groove evenly, so that looseness and pullout between the internal threaded stud and the injection-molding body can be prevented.
Description
Technical field
The utility model relates to a kind of pipe fitting and uses component, especially is embedded in the female adapter of injection molding body.
Background technique
At present numerous pipe fitting joint structures is that the inipple of metal is embedded in injection molding body inside, has practiced thrift valuable metal under the situation of usage requirement satisfying.This pipe fitting joint in use often occurs occurring loosening even pull-off between metal threaded joint and the injection molding body, badly influences the use of pipe fitting joint.
Summary of the invention
The utility model provides a kind of female adapter that can firmly be connected in injection molding body for the screw thread cylinder that the solution existing technology in use exists rocks, breaks away from easily defectives such as injection molding body.
The technological scheme that the utility model solves existing issue is: a kind of female adapter that is used for the pipe fitting injection molding body; Comprise the internal thread cylinder that is embedded in injection molding body; As improvement; The external wall of described internal threaded column radially is arranged with at least one annular slot, is evenly equipped with some gap on the cell wall of described at least one annular slot, described gap radial arrangement.
As further improvement, the said internal thread cylinder upper end that is embedded in injection molding body is provided with the ring edge of protrusion.
Above-mentioned gap is V word shape or inverted dovetail shaped.
The utility model compared with prior art, its beneficial effect is to offer gap through being provided with in internal thread cylinder and injection molding body connecting part to be uniformly distributed with on annular slot and the cell wall at annular slot, can prevent that internal thread cylinder and injection molding body from becoming flexible pull-off.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Comprise the internal thread cylinder 1 that is embedded in injection molding body referring to this case study on implementation of Fig. 1, internal thread cylinder 1 outer wall radially is arranged with at least one annular slot 2, is evenly equipped with some gap 3, gap 3 radial arrangement on the cell wall 21 of at least one annular slot 2.Internal thread cylinder 1 upper end is provided with the ring of protrusion along 4, can prevent that internal thread cylinder 1 and injection molding body from relatively rotating, and moves axially.
As preferably, gap is V word shape or inverted dovetail shaped, and the cell wall 21 between the two contiguous gap is roughly dovetail shaped, can closely cooperate with injection molding body 1.
Claims (3)
1. female adapter that is used for the pipe fitting injection molding body; Comprise the internal thread cylinder that is embedded in injection molding body; It is characterized in that: the external wall of described internal threaded column radially is arranged with at least one annular slot; Be evenly equipped with some gap on the cell wall of described at least one annular slot, described gap radial arrangement.
