Abstract
The utility model relates to a plastic-lining pipe coupling, which is composed of a positive joint with a cycle of metal external thread and a negative joint with a cycle of metal internal thread. The utility model is characterized in that a cycle of plastic lining is arranged within a cycle of metal external thread of the positive joint; a plastic connecting piece and the metal internal thread form into an integral body with the plastic lining through injection molding; a plastic body forms an integral body through injection molding with the outer of the metal external threads of the negative joint; the positive joint is provided with convex rib. Compared with the prior art, the utility model has the advantages in that: 1. The cost of production is greatly reduced due to the adoption of the above-mentioned structure which substantially reduces the usage of metal material, in particular copper; 2. The strength and service life achieves the effect of prolonging service life rather than shortening owing to using plastic. 3. The structure is reasonable and installation is simple and reliable.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of pipe joint that is applicable to that aluminium-plastic composite pipe and plastic tube connect.
Background technique
In people's daily production and life, various pipelines are transport of water, the necessary tool of gas, the pipe joint that connects between the tube and tube also seems particularly important, existing copper pincers part pipe joint is risen sharply owing to the copper valency, cost of production is too high, make the user be difficult to bear its expensive price, adopt simple hawkbill spare as pipe joint, getting rusty easily influences the working life of pipe joint and iron rust can influence water quality, make pipe joint if adopt simple plastics, its intensity is not ideal enough again, influences the working life of pipe joint equally, and it is not high therefore to search out a kind of cost, intensity is reliable, the pipe joint of long service life is the ideal of industry.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of cost is low, intensity is reliable, the plastics lined pipe joint of long service life.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of plastics lined pipe joint, comprise a male connector and a negative joint, it is characterized in that: be provided with a circle plastic inner lining in the circle metal external thread of described male connector with circle metal internal thread that is complementary with it with a circle metal external thread.
In order to solve the problems of the technologies described above, the utility model adopts following further technological scheme:
One plastic fastening and metal external thread and plastic inner lining are injected into one.
One circle metal internal thread of described negative joint is and its injection moulding all-in-one-piece plastics outward.
Described male connector is provided with the rib of projection.
The utility model beneficial effect compared with prior art is: 1, because the employing said structure greatly reduces the consumption of the use amount, particularly copper of metallic material, thereby greatly reduce cost of production; 2, do not reduce in its intensity and working life, reach the effect that increases the service life because having used plastics; 3, it is rational in infrastructure, and is easy for installation, reliable.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is the sectional view of male connector.
Fig. 3 is the sectional view of negative joint.
Fig. 4 is that the A of Fig. 2 is to view.
Embodiment
As shown in Figure 1, a kind of plastics lined pipe joint, comprise a male connector 2 and a negative joint 4, male connector 2 one ends have a circle metal external thread 1, be provided with a circle plastic inner lining 5, one plastic fastenings 6 in the metal external thread 1 and be injected into one with metal external thread 1 and plastic inner lining 5, the termination 9 of plastic fastening 6 is used for connection pipe fitting, install for convenience, male connector 2 is provided with the rib 8 of projection.Negative joint 4 has a circle metal internal thread 3 that is complementary with male connector 2, and circle metal internal thread 3 is outer be and its injection moulding all-in-one-piece plastics 7 for this, plastics 7 can be made into two lead to, threeway, four-way, elbow structure, the termination 10 of plastics 7 is used for connection pipe fitting.During use, male connector 2 and negative joint 4 are screwed by screw thread, the termination 9 and the pipe fitting welding of the plastic fastening 6 of male connector 2, installation is finished in the termination 10 and the pipe fitting welding of the plastics 7 of negative joint 4.
Adopt the pipe joint of said structure, male connector 2 and negative joint 4 are meshing with each other, owing to be provided with plastic inner lining in its metal external thread, internal thread is injected with plastics outward, greatly reduce the use amount of metallic material on the one hand, the consumption of copper particularly, thereby greatly reduce cost of production, on the other hand, male connector 2 still adopts metallic material to make with negative joint 4 intermeshing internal threads and outside thread, its intensity and working life are not reduced because having used plastics, use with reality after tested, its effect can clamp the part pipe joint with copper fully and compare favourably, and price only is equivalent to copper pincers part pipe joint half, reduce user's cost greatly, save metals resources such as copper again, its practicability is very strong.
The foregoing description is only for the usefulness that the utility model is described, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, under the situation that does not break away from spirit and scope of the present utility model, can also make various variations and modification, so all technological schemes that are equal to also belong to category of the present utility model.
