Abstract
The utility model relates to the technical field of fittings for a construction water supplying and discharging system and a heating system and more concretely relates to an injection molding fitting with a copper insert. The injection molding fitting comprises an injection molding member and the copper insert, wherein one end of the copper insert is embedded in the injection molding member; the other end of the copper insert is a free end; and the end surface of the end part of the copper insert inserted in the injection molding member is provided with end surface water blocking grooves. A plurality of water blocking grooves are arranged on the injection molding fitting with the copper insert; the copper insert and the injection molding member can be strongly sealed via the internal surface, the external surface and the end surface, so great sealing effect is achieved; and the injection molding fitting with the copper insert has wide applications and strong practicality, thereby being suitable for the construction water supplying and discharging system and the heating system.
Description
Technical field
The utility model relates to the accessory technical fields such as building water supply and drainage, heating system, more specifically, relates to a kind of injection moulding accessory with copper insert.
Background technique
In prior art,, as PP-R, PB, PE, PE-RT etc., because the expansion coefficient of copper insert and injected plastics material is different, often there is Seepage between copper insert and plastic parts in the injection moulding accessory with copper insert used in plumbing and heating system.If this problem can not be well solved, will make pipe-line system sealing have hidden danger, to promoting to mould for steel band, carry out certain resistance.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of injection moulding accessory with copper insert of good airproof performance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of injection moulding accessory with copper insert, comprise working of plastics and copper insert, one end of described copper insert is embedded in working of plastics, the other end is free end, described in be embedded in the copper insert in working of plastics end end face be provided with end face water stopping trough.
Preferred scheme is, described in be embedded in the copper insert in working of plastics end near end face periphery, be provided with periphery water stopping trough.
Further preferred scheme is, described in be embedded in the end of the copper insert in working of plastics and encircle and be provided with interior ring water stopping trough.
To sum up, utilize many places that water stopping trough is set and increase the sealing between copper insert and working of plastics.
Further preferred scheme is, described in be embedded in the copper insert in working of plastics end near free-ended periphery, be provided with spline boss, described spline boss is just embedded in working of plastics and in the end of working of plastics.Described spline boss is one or more.
Further preferred scheme is, the free end periphery of described copper insert is provided with the torsional surface of clamping when installing.Described torsional surface is octagon or hexagon, and design torsional surface, is convenient to the clamping in installation process, reduces spraining of copper insert and working of plastics.
Compared with prior art, the utlity model has following beneficial effect:
The injection moulding accessory design multiple tracks water stopping trough of the utility model band copper insert, by inside and outside, end face etc., increase the sealing between copper insert and working of plastics, reach sealing effect, also be designed with the moment of torsion that spline boss that quantity do not limit strengthens copper insert and working of plastics, be also designed with torsional surface simultaneously, facilitate the clamping in installation process, reduce spraining of copper insert and working of plastics, the utility model is widely used, practical, adapts to the uses such as building water supply and drainage and heating system.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model embodiment copper insert.
Fig. 2 is the side schematic view of the utility model embodiment copper insert.
In figure, copper insert 1, end face water stopping trough 11, periphery water stopping trough 12, interior ring water stopping trough 13, spline boss 14, torsional surface 15.
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, in accompanying drawing, identical or similar label indicates identical or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment who is described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
The utility model discloses a kind of injection moulding accessory with copper insert, comprises working of plastics and copper insert 1, and one end of copper insert 1 is embedded in working of plastics, and the other end is free end.
As shown in Figure 1 to Figure 2, the end end face that is embedded in the copper insert 1 in working of plastics is provided with end face water stopping trough 11, this embedding end is provided with periphery water stopping trough 12 near end face periphery, in this end, ring is provided with interior ring water stopping trough 13, by water stopping trough is set, increases the sealing between copper insert and working of plastics.
In addition, this embedding end is provided with spline boss 14 near the free-ended periphery of copper insert 1.Spline boss quantity is not limit.
Also have, for convenience of the clamping in installation process, reduce spraining of copper insert and working of plastics, the free end periphery of copper insert is provided with the torsional surface 15 of clamping when installing.This torsional surface is typically designed to octagon or hexagon.
To sum up, the injection moulding accessory of the utility model band copper insert is by design multiple tracks water stopping trough, by inside and outside, end face etc., increase the sealing between copper insert and working of plastics, reach sealing effect, strengthen the Adhesion force between copper insert and plastics, assurance is with the injection moulding accessory of copper insert sealing in use, and the utility model application is very extensive.
These are only preferred embodiment of the present utility model, but design concept of the present utility model is not limited to this, all insubstantial modifications of utilizing this design to make the utility model, within also all falling into protection domain of the present utility model.
