Abstract
The utility model relates to a clamping-pressing type metal pipe coupling, which solves the problems that the metal pipe connecting piece in the prior art, including complex connection method, poor connection performance, poor sealing effect and waste of materials. The clamping-pressing type metal pipe coupling is characterized in that the inner diameter of the coupling is matched with the outer diameter of a metal pipe, an annular groove is arranged on the inner wall of the coupling, a seal ring is arranged inside the annular groove, and bells and spigots are arranged on the two sides of the annular groove and are fixedly connected with the metal pipe by compressional deformation. The clamping-pressing type metal pipe coupling can be conveniently and simply connected with the metal pipe. Because of the seal ring in the annular groove arranged on the coupling, the metal pipe coupling has good sealing performance. Also, the metal pipe coupling has good connection performance and long service life, so as to avoid frequent replacement of material and save cost.
Description
Technical field
The utility model relates to a kind of metal tube link, refers in particular to a kind of clamp-press type metallic pipe coupling.
Background technique
What traditional metal tube link was connected basic employing with metal tube is to be threaded, to weld and the flange connection, but these connecting means complexity also can cause the waste of material in the connection procedure, and cost is higher.In addition, the poor sealing performance that pipe fitting is connected with metal tube is through phenomenons such as leaking appear in regular meeting; need artificial maintenance, bring unnecessary trouble, and leak and to cause tubing to be corroded to the user; reduce the working life of tubing and needed replacing, caused waste of material to a certain extent.
Summary of the invention
In order to overcome shortcoming in the background technique with not enough, the utility model provide a kind of easy to connect, switching performance good, good sealing effect and save the clamp-press type metallic pipe coupling of material.
The technological scheme of technical solution problem: a kind of clamp-press type metallic pipe coupling, comprise the pipe fitting body, described pipe fitting body is provided with the connecting head that cooperates with metal tube, it is characterized in that: described connecting head internal diameter cooperates with the metal tube external diameter, described connecting head is provided with annular groove, be provided with seal ring in the described annular groove, the both sides of described annular groove are joint socket, and described joint socket adopts extrusion-deformation to fixedly connected with metal tube.
Described described pipe fitting body is provided with the positioning step with the screens of metal tube head.
Described joint socket inwall is along the annular groove several angle that is inclined upwardly.
Described pipe fitting body is straight tube, bend pipe or three-way pipe.
The beneficial effects of the utility model are: because connecting head is fixedlyed connected with metal tube employing extrusion-deformation, just can make both fixedly connected after metal tube insertion connecting head is pushed with special purpose extrusion press, connecting means is simple, convenient.In addition, connecting head is provided with annular groove, be provided with seal ring in the annular groove and make the good sealing effect of connecting head of metal tube, and the switching performance of connecting head is good, and long service life has often been avoided more conversion materials, provides cost savings.

Among the figure, pipe fitting body 1, positioning step 2, joint socket 3, annular groove 4, seal ring 5, metal tube 6, extruding vestige 7.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
Shown in figure, a kind of clamp-press type metallic pipe coupling, comprise pipe fitting body 1, described pipe fitting body 1 is provided with the connecting head that cooperates with metal tube 6, described connecting head internal diameter cooperates with metal tube 6 external diameters, and described connecting head is provided with annular groove 4, is provided with seal ring 5 in the described annular groove 4, the both sides of described annular groove 4 are joint socket 3, and described joint socket 3 adopts extrusion-deformation to fixedly connected with metal tube 6.According to such scheme, because connecting head is fixedlyed connected with metal tube 6 employing extrusion-deformations, after being pushed with special purpose extrusion press, metal tube 6 insertion connecting heads just can make both fixedly connected, connecting means is simple, convenient.In addition, connecting head is provided with annular groove 4, be provided with seal ring 5 in the annular groove 4 and make the good sealing effect of connecting head of metal tube 6, and the switching performance of connecting head is good, and long service life has often been avoided more conversion materials, provides cost savings.
In the utility model, pipe fitting body 1 is provided with the positioning step 2 with metal tube 6 head screens.Make that metal tube 6 screens were played locating effect at positioning step 2 places when metal tube 6 was connected with metallic pipe coupling.
In the utility model, described joint socket 3 inwalls are along annular groove 4 several angle that is inclined upwardly.Be set to fillet at annular groove 4 and joint socket 3 inwall intersections, make the tubing distortion cause decreased performance because of crushing strength is excessive when effectively having avoided connection, strengthen the working life of tubing and improved switching performance, and can prevent annular groove 4 to be squeezed and be out of shape, seal ring 5 leaves the space of unfolding, and makes sealing effect improve greatly.
In the utility model, described pipe fitting body 1 is straight tube, bend pipe or three-way pipe.The utility model is preferentially selected bend pipe for use, and certainly, pipe fitting body 1 also can be set to four-way, five-way pipe etc.
The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
