Abstract
The utility model discloses an outer thread insert, including the radius pipe, install the bare pipe that the diameter is less than the radius pipe on the radius pipe, install external thread pipe on the bare pipe, the last throat pipe of installing of external thread pipe, radius pipe, bare pipe, screwed pipe and integrative manufacturing of throat pipe form. An outer thread insert, the radius pipe, bare pipe, screwed pipe and the throat pipe that form through an organic whole manufacturing, notch, slot and external screw thread that the cooperation was seted up make to mould and combine closely to be difficult for extracting with the inserts, and be difficult rotatory, improves the mechanical strength of inserts, does benefit to the long -term use of inserts.
Description
Technical field
The utility model relates to pipe fitting field, especially a kind of external screw thread insert.
Background technique
Improve constantly along with informationalized, much traditional product is all in renewal, and such as plastic replaces various metal pipe element, plastic needs the cooperation of inserts, but the combination of plastic and inserts often defective tightness, and insert surface needs to do to change, increasing friction force, makes inserts not be drawn out easily or non rotating.
Model utility content
The purpose of this utility model is to provide a kind of external screw thread insert, by integrally manufactured rounding pipe, screw-thread-free pipe, threaded pipe and necking pipe, coordinate recess, groove and the outside thread offered that plastic is combined with inserts closely, be not drawn out easily, not easily rotate, improve the mechanical strength of inserts, be beneficial to the Long-Time Service of inserts.
In order to achieve the above object, the technical solution of the utility model is:
A kind of external screw thread insert, comprise rounding pipe, described rounding pipe is provided with the screw-thread-free pipe that diameter is less than rounding pipe, described screw-thread-free pipe is provided with male-pipe, described male-pipe is provided with necking pipe, described rounding pipe, screw-thread-free pipe, threaded pipe and necking pipe is integrally manufactured forms.
Described rounding pipe comprises the first integrally manufactured flange collar, the first recessed circle, the second flange collar, the second recessed circle, the 3rd flange collar successively, described 3rd flange collar is provided with screw-thread-free pipe, described first flange collar offers recess.
Described first flange collar second flange collar the 3rd flange collar diameter is identical, and the recessed loop diameter of described first recessed circle second is identical.
Described screw-thread-free pipe upper end offers the first relatively identical groove and the second groove.
Described male-pipe offers outside thread.
The beneficial effects of the utility model are: a kind of external screw thread insert of the present utility model, by integrally manufactured rounding pipe, screw-thread-free pipe, threaded pipe and necking pipe, coordinate recess, groove and the outside thread offered that plastic is combined with inserts closely, be not drawn out easily, not easily rotate, improve the mechanical strength of inserts, be beneficial to the Long-Time Service of inserts.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
