Abstract
The utility model relates to an extrusion type pipe joint, which comprises a pipe joint body and a pipe sleeve. An interface for connecting tubular parts is arranged at the end of the pipe joint body. A sealed gasket is arranged between the pipe joint and the pipe sleeve. The utility model is characterized in that: the diameter of an outer ring of the sealed gasket is gradually reduced from outside to inside. The outer ring has a slant cross section. The interface has a slant surface matching with the outer ring of the sealed gasket. Compared to the prior art, the utility model has the advantages that; firstly, with the above structure, a more reasonable movement of the elements and a higher compressibility of the sealed gasket are ensured, thereby effectively preventing leak; secondly, the pipe joint tubular parts is adopted to achieve a steady connection. The utility model has low clearness demand to the surface of the pipe, has no cutting demand when in the dismounting time, and has no renew fusing demand when in reconnect time. The utility model is convenient to installation to save time and effort, and particularly suited to the frequent installation needed occasions.
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 necessary tool of transport of water, gas.Mostly pipeline in the past is metallic conduit, exists many shortcomings.Industry has emerged the upsurge that changes the conventional pipelines material both at home and abroad in recent years, present stage mature technique be to replace metallic conduit with aluminium-plastic composite pipe or plastic tube, the Placement of existing aluminium-plastic composite pipe or plastic tube, usually adopt hot melt or electric smelting method to connect, this Placement needs special device, require very high to pipe fitting end face turbidity test, and must cut during dismounting, still need welding again when reconnecting, waste time and energy, fragile pipe fitting, to the occasion of the frequent dismounting of need, its drawback is especially outstanding.
Summary of the invention
Technical problem to be solved in the utility model provides the extruding type pipe joint of a kind of easy accessibility, good seal performance.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of extruding type pipe joint, comprise pipe joint body, engaging body, the termination of pipe joint body is provided with the interface of connection pipe fitting, be provided with seal ring between pipe joint body and the engaging body, it is characterized in that: the inside gradually undergauge in the outer ring of described seal ring, the section shape of outer ring is the inclined-plane, described interface forms the inclined-plane that matches with the outer loop-shaped of seal ring.
In order to solve the problems of the technologies described above, the utility model adopts following further technological scheme:
Described engaging body is near the inside gradually undergauge of the inner ring of its end, and the section shape of its inner ring is the inclined-plane.
Described pipe joint body is provided with the rib of projection.
Described engaging body is provided with the rib of projection.
The utility model beneficial effect compared with prior art is: 1, owing to adopt said structure, it is more reasonable to make that each parts walk, and the compressibility of seal ring is higher, thereby has effectively prevented leakage; 2, adopt this pipe joint connection pipe fitting, connect reliably, less demanding to pipe fitting end face turbidity test, do not need cutting during dismounting, reconnecting does not need welding again, and easy accessibility is time saving and energy saving, needing to be particularly suitable for the occasion of frequent dismounting.

Embodiment
As shown in Figure 1, a kind of extruding type pipe joint comprises pipe joint body 1, engaging body 2, is provided with seal ring 3 between pipe joint body 1 and the engaging body 2.
Figure 2 shows that pipe joint body 1 sectional view.The two ends of pipe joint body 1 is symmetrical arranged the interface 5 of connection pipe fitting 4, and interface 5 is provided with outside thread, forms the inclined-plane 6 that the shape with seal ring 3 outer ring fore-ends matches in the interface 5, and pipe joint body 1 cylindrical shell is provided with the rib 7 of projection.
Figure 3 shows that engaging body 2 sectional views.Be provided with the internal thread that matches with outside thread on the interface 5 in the engaging body 2, near the inside gradually undergauge of the inner ring of engaging body 2 ends, the section shape of its inner ring is inclined-plane 8, and engaging body 2 is provided with the rib 9 of projection.
Figure 4 shows that seal ring 3 sectional views.The inside gradually undergauge in the outer ring of seal ring 3, the section shape of outer ring is inclined-plane 10, and these inclined-plane 10 fore-ends match with the inclined-plane 6 of moulding in the interface 5, and the internal diameter of seal ring 3 is that liquid sealing cooperates with the external diameter of connecting tube 4.
During use, engaging body 2 is inserted in from the cut ends of connecting tube 4, little one of seal ring 3 is towards interface 5, because of the inclined-plane 6 in the shape of seal ring 3 outer ring fore-ends and the interface 5 matches, so the fore-end of seal ring 3 is embedded in the interface 5, then pipe fitting 4 is inserted in the seal ring 3, rotary sleeve zoarium 2, in engaging body 2 rotation drive-in steps, engaging body 2 continuous crush seal circles 3 make seal ring 3 distortion backs tightr with cooperating of 5 interfaces, simultaneously also tightr with cooperating of pipe fitting 4, near the inside gradually undergauge of the inner ring of engaging body 2 ends, make engaging body 2 cut the surface of pipe fitting 4 better, engaging body 2 is screwed finish assembling at last.Dismounting for convenience all is provided with the rib of projection on pipe joint body 1 and the engaging body 2, these ribs can play increase frictional force, and during dismounting, does not need tool using, and free-hand operation just can easily be finished.
This tube joint assembly is few, and the preparation of parts is convenient, reliable on-site, convenient management, and dismounting speed is fast, does not need tool using, low cost of manufacture, not fragile pipe fitting, long service life is a kind of novel pipe joint.
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.
