Description
Technical field
The utility model relates to the technical field of the feedwater piping of health environment-friendly, more specifically, relates to Novel loose joint head product structure.
Background technique
Existing feedwater PP-R union product structure, as shown in Figure 1, it is also formed by four component combinations such as outside thread main body 1, nut 2, "O"-ring 3 and unions 4.The female end of outside thread main body 1 parts of product difference compared with the wall thickness of threaded end is comparatively large, threaded end because of wall thickness large, from the appearance, this portion retracts is comparatively large, and flow liner is a lot, and unstable product quality, has hidden danger, and customer satisfaction is not high.So the union product defectiveness of existing structure, not only have the hidden danger of quality instability, and materials are many, cost is high, so product applicability is not high.
Summary of the invention
The utility model, for overcoming at least one defect described in above-mentioned prior art, provides Novel loose joint head product structure, and its uniform wall thickness, product shrink evenly, are easy to shaping.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: Novel loose joint head product structure, comprise outside thread main body, be located at the union of outside thread main body side, the O type circle be located in outside thread main body, the outside of outside thread main body and union is provided with nut, wherein, described outside thread main body is provided with female end and threaded end, and the latus rectum of described threaded end is divided into two-part, and two-part are connected to chamfering by following current.
Further, described latus rectum size divide sized by two-part, the partial-length that wherein latus rectum is little is shorter, and large partial-length is longer, and following current is located between two-part to chamfering.In this programme, not only the wall thickness of threaded end is comparatively even, and also average compared with female end.With a reasonable transition in ramp down angle between large and small two-part of latus rectum of threaded end.
Further, material reducing position is provided with in the part that described threaded end latus rectum is large.Described outside thread main body is provided with seal groove, and O type circle is located in seal groove.
In this programme, union is PP-R feedwater union.The product uniform wall thickness of novel outside thread main body part, is easy to molding and forming, and product appearance is good, quality is high, and materials are few, lightweight, cost is low.The installation steps of this Novel loose joint head product are as follows: be first encased in the square type seal groove of novel outside thread main body by O type circle; Again union is inserted in nut, and the bellmouth of union exposes to nut; Finally novel outside thread main body and the nut packaging union are engaged to tightly by internal and external threads.
Compared with prior art, beneficial effect is: outside thread main body part wall thickness of the present utility model is comparatively even, and injection moulding is easy, constant product quality; Wall thickness is more even, contraction deformation is less, be easy to molding and forming; Outward appearance is good, quality is high; Materials are few, cost is low.

Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.Describe position relationship in accompanying drawing only for exemplary illustration, the restriction to this patent can not be interpreted as.
As in Figure 2-4, Novel loose joint head product structure, comprise outside thread main body 1, be located at the union 4 of outside thread main body 1 side, the O type circle 3 be located in outside thread main body 1, outside thread main body 1 is provided with nut 2 with the outside of union 4, wherein, outside thread main body 1 is provided with female end 11 and threaded end 12, and the latus rectum of threaded end 12 is divided into two-part, and two-part are connected to chamfering 14 by following current.
Latus rectum size divide sized by two-part, the partial-length that wherein latus rectum is little is shorter, and large partial-length is longer, and following current is located between two-part to chamfering 14.Material reducing position 13 is provided with in the part that threaded end 12 latus rectum is large.Outside thread main body 1 is provided with seal groove, and O type circle 3 is located in seal groove.
The step of concrete installation is as follows: be first encased in the square type seal groove of novel outside thread main body 1 by O type circle 3; Again union 4 is inserted in nut 2, and the bellmouth of union 4 exposes to nut 2; Finally novel outside thread main body 1 is engaged to tightly by internal and external threads with the nut 2 packaging union.
So, the installation of whole product is namely completed.So, the product of this utility model patent, uniform wall thickness, steady quality, lightweight, cost is low (for ￠ 32 union, the outside thread main body of novel product than reality light 3.6g/ only).This outside thread main body part uniform wall thickness, injection moulding is easy, constant product quality.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
