Abstract
The utility model relates to the technical field of pipe fitting structures, and provides an inner screw elbow which is attractive in appearance, lightweight and low in cost. The inner screw elbow comprises an elbow body, a female end is arranged at one end of the elbow body, an internal thread end is arranged at the other end of the elbow body, a stainless steel hoop is arranged on a port of the internal thread end, the outer wall of the internal thread end protrudes outwards, and the wall thickness of the internal thread end is larger than that of the elbow body. Only the outer wall of the internal thread end is thickened, and the wall thickness of elbow body is smaller than that of the internal thread end, so that materials is saved, the inner screw elbow is lightweight, and production cost is reduced.
Description
Technical field
The utility model relates to fitting structure technical field, more specifically, relates to a kind of inner thread elbow.
Background technique
In actual life, inner thread elbow is a kind of connecting pipe part conventional in hot-water heating is installed.As shown in Figure 1, in prior art, inner thread elbow comprises elbow main body, and one end of elbow main body is provided with the female end for being connected with tubing, and the other end of elbow main body is provided with the female end of Matching installation male fitting, and female end is provided with stainless stirrup.Wherein, the wall thickness of elbow main body is consistent with the plastic cement wall thickness of female end, and the screw thread due to female end is injection moulding plastic moulding simultaneously, and that the intensity of the anti-fluid pressure of plastic cement is compared with steel is low, so the wall thickness of female end is thicker, the materials of single product are more, and cost is higher.Because the wall thickness of female end and the wall thickness of female end and main body differ larger, product appearance is difficult to be adjusted, unstable product quality again.In addition, when the female end of product is connected with male fitting, smooth smooth without origin of force because of external form, tighten spanner and be difficult to reverse stressed, product is difficult to tighten sealing; On the contrary, the dismounting of product is also inconvenient.So the inner thread elbow defect of prior art is more, applicability is not high.
Model utility content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of aesthetic in appearance, and quality is light, lower-cost inner thread elbow.
The utility model solves the technological scheme that its technical problem adopts: a kind of inner thread elbow, comprise elbow main body, one end of described elbow main body is provided with female end, the other end of described elbow main body is provided with female end, the port of described female end is provided with stainless stirrup, the outer wall of described female end is outwards outstanding, and the wall thickness of described female end is greater than the wall thickness of elbow main body.The utility model is only by the outer wall thickening of female end, and the wall thickness of elbow main body is less than the wall thickness of female end, saves material, and quality is light, reduces production costs.
In a preferred implementation, the outer wall of described female end is provided with some installation muscle.When mounted, the female end of product is coordinated as internal and external threads with the male fitting of coupling and put forth effort on to install on muscle with spanner to tighten, if while dismantling internal and external threads connection, only need put forth effort on reversion on installation muscle by spanner and exert oneself, can complete the dismounting of internal and external threads, mounting or dismounting are convenient.More preferably, described installation muscle is uniformly distributed at the outer wall of female end.More preferably, the quantity of described installation muscle is 4.
In a preferred implementation, the wall thickness of described female end is consistent with the wall thickness of elbow main body, thereby product wall thickness is even, is easy to molding and forming, simultaneously aesthetic in appearance, constant product quality.
In a preferred implementation, the inwall interference fit of the outer wall of described female end and stainless stirrup, plays reinforing function at the port of female end, and quality is used reliable.
In one embodiment, described inner thread elbow is PVC feedwater inner thread elbow.
The beneficial effects of the utility model are: 1, save material, quality is light, reduces production costs; 2, simple in structure, mounting or dismounting are convenient; 3, product wall thickness is even, is easy to molding and forming, simultaneously aesthetic in appearance, constant product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of inner thread elbow in prior art.
Fig. 2 is an embodiment's of the utility model structural representation.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is an embodiment's of the utility model use schematic diagram.
Accompanying drawing, only for exemplary illustration, can not be interpreted as restriction of the present utility model; For better explanation embodiment, 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 to omit be understandable.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 2 and Figure 3, a kind of inner thread elbow of the present utility model, comprise elbow main body, one end of described elbow main body is provided with female end 11, the other end of described elbow main body is provided with female end 12, the port of described female end 12 is provided with stainless stirrup 13, and the outer wall of described female end 12 is outwards outstanding, and the wall thickness of described female end 12 is greater than the wall thickness of elbow main body.The utility model is only by the outer wall thickening of female end 12, and the wall thickness of elbow main body is less than the wall thickness of female end 12, saves material, and quality is light, reduces production costs.
For ease of mounting or dismounting, the outer wall of described female end 12 is provided with some installation muscle 14, in the present embodiment, is 4, is evenly distributed on the outer wall of female end 12.
In the present embodiment, the wall thickness of described female end 11 is consistent with the wall thickness of elbow main body, thereby product wall thickness is even, is easy to molding and forming, simultaneously aesthetic in appearance, constant product quality.
In the present embodiment, the inwall interference fit of the outer wall of described female end 12 and stainless stirrup 13, plays reinforing function at the port of female end 12, and quality is used reliable.
In the present embodiment, described inner thread elbow is PVC feedwater inner thread elbow.
As shown in Figure 4, the utility model in use, first the female end of the all-plastic inner thread elbow 1 of injection formed and stainless stirrup 13 interference edges are spelled, again the female end of inner thread elbow 1 is coordinated as internal and external threads with the male fitting 2 of coupling and put forth effort on to install on muscle with spanner and tighten, finally that the female end of inner thread elbow 1 is bonding with the tubing 3 use PVC-U binder socket joints that match, thus installation completed.When if dismounting internal and external threads connects, only need put forth effort on to install on muscle by spanner and reverse firmly, can complete the dismounting of internal and external threads.
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 also giving all mode of executions.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
