Description
Technical field
The utility model relates to a kind of linkage structure of inlaying on PPR pipe road.
Background technique
Along with market moulds the universal of pipeline and pipe fitting for hot and cold water feedwater, eliminate metallic conduit and pipe fitting gradually, and the use of PPR plastic pipe is on the fusion sealability of connecting thread metal insert and plastics and cause because torsion is excessive in assembling and produce the impact of rotating sealing produces between metal insert and plastics and have higher requirement.
But the PPR pipe part of existing circulation in the market, often causes loss because of metal insert and plastics fused layer seepage to user; Present most of producer to the design of metal insert also only at external diameter Shang Jialiaoji road groove, convex-concave step is devised at the end face of metal insert, and this structure often torsion is excessive when mounted, be just easy to cause metal insert to loosen, and then cause pipe fitting seepage.So existing pipe fitting needs to be improved, to meet the demand of existing market.
Model utility content
The purpose of this utility model is to provide a kind of linkage structure of inlaying on PPR pipe road, reduces the raw material of inserts, cost-saving, increases sealability simultaneously, prevents the problem of the easy seepage of pipe fitting from occurring, increases structural strength, increases the service life.
For achieving the above object, the technical solution of the utility model is:
The linkage structure of inlaying on PPR pipe road, it is characterized in that: comprise PPR pipe part, metal layer is provided with in described PPR pipe part port inside, damascene body is provided with at inwall place, outer wall place is provided with protection scuff-resistant coating, the inside of described damascene body forms groove, the outer wall of described damascene body is provided with the concavo-convex step of a circle, the port surface of described groove is provided with the concavo-convex step of a circle, port inner wall is provided with a circular arc limit, a convex annular chuck is provided with in described damascene body inwall bottom end, inner groovy is formed between described annular chuck and described bottom, described annular chuck convex 2-5mm, the degree of depth of described inner groovy is 2-4mm.
The utility model is done further preferably, described annular chuck convex 2mm.
The utility model is done further preferably, described annular chuck convex 4mm.
Do further preferably the utility model, the degree of depth of described inner groovy is 2mm.
Do further preferably the utility model, the degree of depth of described inner groovy is 4mm.
The utility model is done further preferably, between described metal layer and described damascene body, is provided with connection strap.
Compared with prior art, the beneficial effects of the utility model:
First; the utility model comprises PPR pipe part; be provided with metal layer in described PPR pipe part port inside, be provided with damascene body at inwall place, outer wall place is provided with protection scuff-resistant coating; such structure can increase the structural strength of whole port; working life is increased, the while of outside, also have received protection.
The second, the inside of the body of damascene described in the utility model forms groove, and the outer wall of described damascene body is provided with the concavo-convex step of a circle, and the port surface of described groove is provided with the concavo-convex step of a circle, and port inner wall is provided with a circular arc limit.The utility model is provided with 2 circle convex-concave steps at the metal insert external diameter position near pipe fitting end face, make the face, front-end and back-end of inserts have convex-concave step simultaneously, namely on the outer wall of described damascene body, the concavo-convex step of a circle is provided with, the port surface of described groove is provided with the concavo-convex step of a circle, the torsion that can play anti-torsion significantly improves, and is fundamentally resolved to easily causing inserts to loosen this problem because installation torsion is excessive.And front and back convex-concave step can pass through press tool once-through, external diameter adds the raw material that convex-concave step additionally reduces inserts, saved cost.
3rd, the utility model is provided with a convex annular chuck in described damascene body inwall bottom end, inner groovy is formed between described annular chuck and described bottom, described annular chuck convex 2-5mm, the degree of depth of described inner groovy is 2-4mm, the utility model is provided with a convex annular chuck in described damascene body inwall bottom end, inner groovy is formed between described annular chuck and described bottom, plastic raw material and the inserts close contact better when injection moulding is merged can be made, thus add sealability.Breach tooth metal insert endoporus in tradition and there is no seal groove, the defect of the easy seepage of pipe fitting.
As from the foregoing, the utility model reduces the raw material of inserts, cost-saving, increases sealability simultaneously, prevents the problem of the easy seepage of pipe fitting from occurring, increases structural strength, increases the service life.
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
