Abstract
The invention provides a copper insert structure for preventing seepage. When an axial groove in the surface of an inner hole of the copper insert structure is filled with plastics in an injection molding mode, the inner wall of the axial groove in the surface of the inner hole prevents the plastics which will retract in the radial direction from retracting, so that the more the plastics retracts, the more closely the plastics is attached to a copper insert, and a better water sealing effect is achieved. When temperature increases, the copper insert will expand, copper on the two sides of the axial groove in the surface of the inner hole can well clamp the plastics, and a good water sealing effect can also be achieved. The plastics is hidden in the axial groove in the surface of the inner hole of the copper insert, water can be better prevented from directly impacting the joint of the plastics and copper, and the anti-seepage safety coefficient is increased. Asawtooth-shaped groove in the outer surface of the copper insert forms two blockage lines through two sharp corners, and the blockage lines and a plastic body can prevent water flow seepage more effectively.
Description
Technical field
The present invention relates to conduit coupling field, more particularly, to a kind of copper insert structure preventing seepage。
Background technology
Current existing supply and drain water system PB, PP-R, PE band copper mold insert product, the structural design of copper mold insert is all simpler, the groove mainly differed in copper piece outer surface processing quantity and shape, inside copper piece, it is typically all smooth straight body or only has one or two groove (see accompanying drawing Fig. 1,11 represent inner groovy, and 12 represent smooth inner wall)；And the plastic cement material two kinds different from copper piece is because material behavior is different, and when Shooting Technique is unreasonable, being either way easy to make both separate, producing gap, thus causing copper piece seepy question。
Summary of the invention
The present invention provides a kind of copper insert structure preventing seepage, solves the problem because copper piece or other metals cause leaking because of the separation shrinking different generation from plastic cement。
In order to reach above-mentioned technique effect, technical scheme is as follows:
A kind of copper insert structure preventing seepage, including copper mold insert and the plastic construction being injection-moulded on copper mold insert, copper mold insert includes thread and through endoporus, also includes the axial notch of bore area, and copper insert structure surface is additionally provided with saw-tooth grooves；Plastic construction utilizes together with the axial notch of bore area is injection-moulded in copper mold insert with the saw-tooth grooves on copper insert structure surface。
Originally it is in invention, when being injected with plastic cement inside the axial notch of bore area, because plastic cement is toward radial contraction, now to may be prevented from plastic cement at the axial notch inwall of bore area and shrink, make plastic cement shrink more tighter with copper piece laminating, just more can well play water sealing effect；The saw-tooth grooves of copper mold insert outer surface, utilizes two wedge angles to form 2 roads and blockades line, more effective hinders current seepage with plastic body。
Further, copper mold insert outer surface is provided with wrench mechanism in thread side。
Further, copper mold insert outer surface is provided with spline groove at the end face of thread offside。
Further, the saw-tooth grooves both sides of copper mold insert are provided with some outer surface grooves。
Further, the interior internal surface of hole near spline groove side is provided with some inner surface recesses。
Compared with prior art, technical solution of the present invention provides the benefit that:
In the present invention, when being injected with plastic cement inside the axial notch of bore area, because plastic cement is can toward radial contraction, now may be prevented from plastic cement at the axial notch inwall of bore area to shrink, plastic cement is made to shrink more tighter with what copper piece was fitted, just more can well play water sealing effect, when temperature is aggravated, copper mold insert meeting swell, the copper on the axial notch both sides of bore area also can well clamp plastic cement, can well play water sealing effect equally, plastic cement is ensconced inside the axial notch of copper mold insert bore area, that better avoids current directly impacts plastic cement and copper binding site, strengthen the safety coefficient of leakproof；The saw-tooth grooves of copper mold insert outer surface, utilizes two wedge angles to form 2 roads and blockades line, more effective hinders current seepage with plastic body。
