Abstract
The utility model provides an utilize rivers reaction force to prevent copper mold insert structure of seepage, this is novel to have the frictional force of production and the power of holding tightly through the plastic in first recess and the second recess and copper spare surface to reach the effect that obstructs rivers and pass through, end design has the axial notch, except original radial guard action, has still increased axial hindrance guard action, and plastics are less at axial receipts scaling, be difficult to to produce the clearance, for radial protection can laminate tighter, when rivers through the axial notch time, the effort of rivers plastic one side in the recess can cause the another side of plastic can obtain a reaction force, more the tight copper spare of laminating, to rivers pass through can play a fine hindrance effect.
Description
Technical field
This utility model relates to conduit coupling field, more particularly, to a kind of copper insert structure utilizing current counteracting force to prevent seepage.
Background technology
Current existing supply and drain water system PB, PP-R, PE band copper mold insert product, the structure design of copper mold insert is the simplest, the groove mainly differed in copper piece outer surface processing quantity and shape, smooth straight body or only one or two groove it is typically all (see accompanying drawing Fig. 1 inside copper piece, wherein 7 represent inner groovy, and 8 represent smooth inner wall)；And two kinds of different materials of plastic cement and copper piece are because material behavior is different, and when Shooting Technique is unreasonable, either way it is easy to make both separate, produces gap, thus cause copper piece seepy question.
Utility model content
This utility model provides a kind of copper insert structure utilizing current counteracting force to prevent seepage, for the problem solving to cause leaking because of the separation shrinking different generations from plastic cement because of copper piece or other metals.
In order to reach above-mentioned technique effect, the technical solution of the utility model is as follows:
A kind of copper insert structure utilizing current counteracting force to prevent seepage, including copper mold insert and the plastic construction being moulded on copper mold insert, copper mold insert offers a through endoporus, copper mold insert bore area offers some first grooves, and the copper mold insert outer surface corresponding in the first groove location offers some second grooves；Copper mold insert one end offers axial notch；Plastic construction utilizes together with the first groove, the second groove and axial notch be moulded in copper mold insert.
In this utility model, copper mold insert endoporus inwall and outer surface Vehicle Processing have the first groove and the second groove, the plastic cement in groove and copper piece surface to have generation frictional force and enclasping force, to reach the effect hindering current to pass through；Copper mold insert one end is designed with axial notch, except original radial direction protective effect, also add axial obstruction protective effect.Plastics are smaller in axial contraction; it is not easy to produce gap; tighter when current are when by axial notch relative to what protection radially can be fitted; the active force of current plastic cement in groove is on one side; the another side that can cause plastic cement can obtain a counteracting force; more fit tight copper piece, to current by a good inhibition can be played.
Further, do not offer one end of axial notch at copper mold insert and offer thread to one section of copper mold insert outer surface of the second groove.
Further, the end face of end offering axial notch is further opened with spline groove.
Further, the copper mold insert outer surface between thread and the second groove offers wrench mechanism.
Compared with prior art, technical solutions of the utility model provide the benefit that:
This utility model has generation frictional force and enclasping force by the plastic cement in the first groove and the second groove and copper piece surface, to reach the effect hindering current to pass through；End is designed with axial notch; except original radial direction protective effect; also add axial obstruction protective effect, plastics are smaller in axial contraction, it is not easy to produce gap; tighter relative to what protection radially can be fitted; when current are when by axial notch, the active force of current plastic cement in groove, the another side of plastic cement can be caused to obtain a counteracting force; more fit tight copper piece, to current by a good inhibition can be played.

Detailed description of the invention
Accompanying drawing being merely cited for property explanation, it is impossible to be interpreted as the restriction to this patent；
In order to the present embodiment is more preferably described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product；
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may will be understood by omission.
With embodiment, the technical solution of the utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1
As Figure 2-3, a kind of copper insert structure utilizing current counteracting force to prevent seepage, including copper mold insert 9 and the plastic construction 10 being moulded on copper mold insert, copper mold insert 9 offers a through endoporus, copper mold insert bore area offers some first grooves 1, and the copper mold insert outer surface corresponding in the first groove 1 position offers some second grooves 2；Copper mold insert one end offers axial notch 3；Plastic construction 10 utilizes together with first groove the 1, second groove 2 and axial notch 3 be moulded in copper mold insert 9.
Do not offer one end of axial notch 3 at copper mold insert 9 and offer thread 4 to one section of copper mold insert outer surface of the second groove 2.
The end face of end offering axial notch 3 is further opened with spline groove 6.
Copper mold insert outer surface between thread 4 and the second groove 2 offers wrench mechanism 5.
Add and forge and press out with spline groove 6 copper piece blank first with forging press man-hour, and process the second groove 2 and the thread 4 of copper mold insert outer surface；Vehicle Processing endoporus and the first groove 1 part of bore area again, and utilize milling machine to process shape changeable wrench position 5, complete the processing of copper piece；Finally the copper piece that Vehicle Processing is good is put into mold cavity, adjusting process injection mo(u)lding.
Copper mold insert 9 endoporus inwall and outer surface Vehicle Processing have the first recessed 1 groove and the second groove 2, the plastic cement in groove and copper piece surface to have generation frictional force and enclasping force, to reach the effect hindering current to pass through；Copper mold insert 9 one end is designed with axial notch 3, except original radial direction protective effect, also add axial obstruction protective effect.Plastics are smaller in axial contraction; it is not easy to produce gap; tighter when current are when by axial notch 3 relative to what protection radially can be fitted; the active force of current plastic cement in groove is on one side; the another side that can cause plastic cement can obtain a counteracting force; more fit tight copper piece, to current by a good inhibition can be played.
The corresponding same or analogous parts of same or analogous label；
Described in accompanying drawing, position relationship is used for the explanation of being merely cited for property, it is impossible to be interpreted as the restriction to this patent；
