Description

Steel plastic compount formula internal thread straight joint
Technical field
The utility model belongs to water tubular union technical field, relates to a kind of steel plastic compount formula internal thread straight joint.
Background technique
In prior art, pipe joint is the main connector element in pipework, current pipe joint has the pipe joint two kinds of metal material and plastic material, wherein joint for plastic tube realizes the location of two stainless steel composite water pipes by forming protruding plastics positioning ring in pipe joint, and then carry out sweat soldering, during sweat soldering, the tube wall that the yielding generation of plastics positioning ring is coarse, tube wall easily produces precipitation, breed bacteria, affect water delivery, and arrange screw member at pipe joint and stainless steel composite water pipe two ends, its cost of production is high.
And how to solve the problem, be the content that those skilled in the art will study.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art, the utility model object is to provide a kind of steel plastic compount formula internal thread straight joint.
For achieving the above object and other relevant objects, the utility model provides a kind of steel plastic compount formula internal thread straight joint, comprises plastic straighttube and stainless steel straight tube; The outlet port, one end of described plastic straighttube is provided with holds the mouth of a river; Be lining in described stainless steel straight tube in the other end of described plastic straighttube; The periphery wall of described stainless steel straight tube is provided with anti-slip part; On the inner circle wall of described stainless steel straight tube, one end is light face straight tube, and the other end is internal thread linkage section; The end face that pipe internal thread linkage section one end put by described stainless steel is concordant with the end face of described plastic straighttube; Described stainless steel straight tube and described straight plastic pipe thermal are connected and fixed.
In technique scheme, related content is explained as follows:
1, in such scheme, described anti-slip part and described stainless steel straight tube one-body molded, anti-slip part contribute to improve plastic straighttube and stainless steel straight tube hot melt time join strength.
2, in such scheme, described in hold the mouth of a river internal diameter size be greater than the outside dimension of described stainless steel straight tube.
3, in such scheme, described anti-slip part comprises annular groove on described stainless steel straight tube outer peripheral surface and annular protrusion.
4, in such scheme, form holding cavity between the periphery wall of described stainless steel straight tube and the described inwall holding the mouth of a river, it is that generation hole and hot melting plastic extrude formation sleeveless jacket that this holding cavity prevents affixed at hot melt.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
The utility model structure is simple, easy to use.The utility model is by the outer wall of stainless steel straight tube arranges anti-slip part, and inwall arranges internal thread linkage section, makes plastic straighttube and stainless steel straight tube when hot melt is fixedly connected with, and join strength increases, and easy processing, cost of production is low.Tubing there will not be hot melting plastic to clamp-on in tubing when connecting simultaneously, and not easily produce precipitation, not easily breed bacteria, water delivery is unobstructed, and cost of production is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, a kind of steel plastic compount formula internal thread straight joint, comprises plastic straighttube 1 and stainless steel straight tube 2; The outlet port, one end of described plastic straighttube 1 is provided with holds the mouth of a river 3; Be lining in described stainless steel straight tube 2 in the other end of described plastic straighttube 1; The periphery wall of described stainless steel straight tube 2 is provided with anti-slip part 4; On the inner circle wall of described stainless steel straight tube 2, one end is light face straight tube, and the other end is internal thread linkage section (not shown); The end face that pipe 2 internal thread linkage section one end put by described stainless steel is concordant with the end face of described plastic straighttube 1; Described stainless steel straight tube 2 is fixed with described plastic straighttube 1 hot-melt adhesive paste.
Described anti-slip part 4 is one-body molded with described stainless steel straight tube 2, and anti-slip part 4 contributes to join strength when improving plastic straighttube 1 and stainless steel straight tube 2 hot melt.
The described internal diameter size holding the mouth of a river 3 is greater than the outside dimension of described stainless steel straight tube 2.
Described anti-slip part 4 comprises annular groove 41 on described stainless steel straight tube 2 outer peripheral surface and annular protrusion 42.
