Abstract
The invention relates to a metal insert embedded in a plastic pipe fitting. The metal insert is composed of metal materials; screw threads can be arranged on the metal insert; the outer periphery of one end of the metal insert is provided with more than two convex teeth; the convex teeth are arranged along the periphery direction; and the convex teeth extend along the radial direction of the column pipe fitting. The arrangement structure facilitates the filling of the plastic materials in the injection molding process, thus the convex teeth have the functions of preventing the metal insert from rotating relatively to the plastic piece and preventing the metal insert from pulling away.
Description
Technical field:
The present invention relates to conveying technology, relate in particular to the plastic cement pipe fitting of embedded metal link, particularly a kind of metal insert in the plastic cement pipe fitting.
Background technique:
The plastic cement products of band damascene part extensively obtains using, and can reduce cost of material.The available technology adopting Shooting Technique is embedded in metal insert in the plastic cement pipe fitting.But the existing structure that prevents that metal insert from rotating with respect to plastic parts generally is to adopt axially extended double wedge, this class double wedge is in some injection moulding process or produce to fill bad and cause seepage, and, such double wedge only plays and prevents metal insert with respect to the effect that plastic parts rotates, and can not prevent that metal insert from deviating from plastic body.
Summary of the invention:
The object of the present invention is to provide a kind of metal insert in the plastic cement pipe fitting, described this metal insert in the plastic cement pipe fitting will solve plastic material in the prior art and fill bad technical problem, and further improves and prevent that metal insert from deviating from the ability of plastic body.
This metal insert in the plastic cement pipe fitting of the present invention is made of metal tube, the material that described metal tube adopts is a copper, described metal tube can be provided with screw thread, wherein, one end excircle of described metal tube is provided with the double wedge of two above numbers, and described double wedge is along the circumferential direction arranged.
Further, described double wedge is along the radially extension of metal tube.
Working principle of the present invention is: in injection moulding process, plastic body directly is filled between metal insert circumferential surface upper raised teeth.Plastic body and double wedge interact can stop metal insert swing offset in plastic body under twisting force, and then solve the problem that causes metal and the infiltration of plastic body junction plane because of metal insert swing offset in plastic body, and can play certain metal insert that prevents and deviate from the effect of plastic body.
The present invention compares with prior art, and its effect is actively with tangible.Cylindrical one end of the metal insert of the present invention in being embedded in the plastic cement pipe fitting is provided with double wedge, help the filling of plastic material, after it is embedded in the plastic cement pipe fitting through injection moulding process, double wedge and plastic cement interact and can bear the torsion load of certain metal insert, avoid metal insert and plastic cement pipe fitting to relatively rotate.The end face of inserts double wedge can avoid inserts along its axial moving simultaneously, has strengthened the combination force between metal insert and the plastic cement pipe fitting effectively.
Description of drawings:
Fig. 1 is the sectional view of a kind of metal insert in the plastic cement pipe fitting of the present invention.
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, metal insert in plastic body 1 of the present invention, constitute by metal tube 2, the material that described metal tube 2 adopts is a copper, on the described metal tube 2 screw thread can be set, wherein, an end excircle of described metal tube 2 is provided with the double wedge 3 of two above numbers, and described double wedge 3 is along the circumferential direction arranged.
Further, described double wedge 3 is along the radially extension of metal tube 2.
The working procedure of present embodiment is: in injection moulding process, plastic body directly is filled between the metal tube 2 circumferential surface upper raised teeths 3.This double wedge that radially extends distributes and can improve the filling of plastic material under some situation.Plastic body 1 interacts with double wedge 3 can stop metal tube 2 swing offset in plastic body 1 under twisting force, and then solves the problem that causes metal tube 2 and plastic body 1 junction plane to seep water because of metal tube 2 swing offset in plastic body 1.And the end face of double wedge 3 can also play certain effect that metal tube 2 is deviate from that prevents from plastic body 1.
Claims (3)
1. metal insert in the plastic cement pipe fitting, constitute by metal tube, the material that described metal tube adopts is a copper, and it is characterized in that: an end excircle of described metal tube is provided with the double wedge of two above numbers, and described double wedge is along the circumferential direction arranged.
2. a kind of metal insert in the plastic cement pipe fitting as claimed in claim 1 is characterized in that: described double wedge is along the radially extension of metal tube.
