Abstract
The utility model provides an improved plastic metal pipe fitting which is composed by the junction of a plastic part and a metal inlaying piece. One end of the plastic part is wrapped at the periphery of the metal inlaying piece, a circumferential position-limiting structure and an axial position-limiting structure are arranged in a joint face between the plastic part and the metal inlaying piece, and an isolating protective layer which is adhered on the metal inlaying piece is arranged in the joint face between the plastic part and the metal inlaying piece. An internal thread or an external thread is arranged in the metal inlaying piece. The isolating protective layer is composed of an electroplating layer. The metal inlaying piece is a material for forming the structure of the pipe fitting, and any second kind of material is not adhered on the exposed surface after the metal inlaying piece is assembled with the plastic piece. The isolating protective layer arranged in the joint face between the plastic pipe fitting and the metal inlaying piece can prevent long-term contact between some metal components and the plastic part, thereby protecting the long-term using performance of plastic materials; as other surfaces of the metal inlaying piece are directly exposed, common consumers can easily recognize the material of the metal inlaying piece.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to piping element, particularly a kind of improved plastic cement metal pipe element.
Background technique:
Plastic cement pipe fitting product does not allow direct mantle fiber, runs into the occasion that is threaded and just need adopt threaded damascene part in the plastic cement pipe fitting.In the prior art, the damascene part extensively adopts brass material.But copper contacts the long-term usability that may influence plastic material with plastic parts is long-term, thereby influences the life-span, therefore need make Nickel Plating Treatment to damascene part surface.But behind the damascene part plating nickel on surface, ordinary consumer is difficult to see clearly the material of damascene part.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved plastic cement metal pipe element, and described this improved plastic cement metal pipe element will solve in the prior art that the whole nickel plating of damascene part make ordinary consumer be difficult to see clearly the technical problem of damascene part material on the plastic cement pipe fitting.
This improved plastic cement metal pipe element of the present utility model is engaged by plastic cement part and a damascene part and constitutes; one end of described plastic cement part is coated on the periphery of described damascene part; plastic cement part and damascene part are provided with circumferential limit structure and axial limiting structure in the mating face; it is characterized in that: be provided with an isolated protective layer in the mating face of described plastic cement part and damascene part, described isolated protective layer is attached on the damascene part.
Further, be provided with internal thread or outside thread in the described damascene part.
Further, described isolated protective layer is made of an electrodeposited coating.
Concrete, the damascene part described in the utility model is the material that constitutes fitting structure, the exposed surface after assembling with plastic parts is not attached with any second kind of material.
Working principle of the present utility model is: be provided with and only be arranged on plastic cement partly with damascene part mating face in isolated protective layer prevent that some metal ingredient copper from contacting for a long time with plastic parts; the long-term usability of protection plastic material; other surfaces of damascene part directly expose, and ordinary consumer is seen clearly the material of damascene part easily.
The utility model and prior art compare, and its effect is actively with tangible.The utility model is arranged on plastic cement part can prevent that with isolated protective layer in the damascene part mating face damascene part from contacting for a long time with plastic parts; the long-term usability of protection plastic material; other surfaces of damascene part directly expose, and ordinary consumer is seen clearly the material of damascene part easily.
Description of drawings:
Fig. 1 is the cross-sectional schematic of improved plastic cement metal pipe element of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1; improved plastic cement metal pipe element of the present utility model; constitute by plastic cement part 1 and damascene part 2 joints; one end of described plastic cement part 1 is coated on the periphery of described damascene part 2; plastic cement part 1 and damascene part 2 are provided with circumferential limit structure and axial limiting structure in the mating face; wherein, be provided with an isolated protective layer 3 in the mating face of described plastic cement part 1 and damascene part 2, described isolated protective layer 3 is attached on the damascene part 2.
Further, be provided with internal thread or outside thread in the described damascene part 2.
Further, described isolated protective layer 3 is made of an electrodeposited coating.
Concrete, the damascene part described in the utility model is the material that constitutes fitting structure, the exposed surface after assembling with plastic parts is not attached with any second kind of material.
