Abstract
The utility model discloses an external thread joint for the injection body of a pipe fitting, comprising a hollow connector, wherein an external thread is arranged at one end of the connector, and a cylinder at the other end of the connector is connected in the injection body in an embedding manner; as an improvement, at least one annular groove is radially arranged on the outer wall of the cylinder which is connected in the injection body in an embedding manner, the cylinder is uniformly distributed with at least one radial groove which is intersected with the annular groove, and the radial groove is ended at the external thread of the connector. According to the utility model, the loosening and pulling-off of the external thread joint and the injection body can be prevented by arranging the annular groove at the end of the cylinder which is connected in the injection body in an embedding manner, and at least one radial groove which is intersected with the annular groove.
Description
Technical field
The utility model relates to a kind of pipe fitting and uses component, especially is embedded in the male connection 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 male connection 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 male connection that is used for the pipe fitting injection molding body; The connecting head that comprises hollow connects first end and is provided with outside thread, and the cylinder of the other end is embedded in the injection molding body; As improvement; The cylinder outer wall that is embedded in the injection molding body radially is arranged with at least one annular slot, and it is some that cylinder is evenly equipped with the radial groove that intersects with at least one annular slot, and described radial groove terminates in the outside thread place of connecting head.
As further improvement, the described cylinder that is embedded in the injection molding body is provided with cyclic convex edge.
As further improvement, described radial groove is V word shape or inverted dovetail shaped.
The utility model compared with prior art, its beneficial effect be through be provided with at interlocking and cylinder end in the injection molding body annular slot and with the radial groove that at least one annular slot intersects, can prevent that male connection and injection molding body from becoming flexible pull-off.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The connecting head 1 that comprises hollow referring to this case study on implementation of Fig. 1; Connecting head 1 one ends are provided with outside thread 2; The cylinder 3 of the other end is embedded in the injection molding body; Cylinder 3 outer walls that are embedded in the injection molding body radially are arranged with at least one annular slot 31, and it is some that cylinder 3 is evenly equipped with the radial groove 32 that intersects with at least one annular slot 31, and radial groove 32 terminates in the outside thread place of connecting head 1.Radial groove 32 is V word shape or inverted dovetail shaped in this case study on implementation, and the cell wall between the two contiguous radial grooves 32 is roughly dovetail shaped, can closely cooperate with injection molding body.
The cylinder 3 that is embedded in the injection molding body is provided with cyclic convex edge 33, when manufacturing, can together insert in the injection molding body with cylinder 3, can effectively prevent to produce between male connection and the injection molding body loosening, pull-off.
