The outer end of described location nut sets screens, and described location nut is connected on the chimb of second pipe by screens.Described location hollow bolt directly can be against on the chimb of the first pipeline with front end, it is also possible to is that tail end is set screens and is connected on the chimb of the first pipeline by screens.
Described location hollow bolt can be that an integral hollow is ring-type, can also be more than one multistage separate type arcuation, if multistage Separated type combination, then when producing assembling, first hollow bolt need not be worn into the first the most folded over chimb of pipeline, directly can position nut after spelling and spin.
A better embodiment of the present utility model is, it is respectively provided with sealing ring between the outer wall of described inner connection tube and the inwall of described first pipeline and the inwall of described second pipe, realizes being tightly connected of described inner connection tube and described first pipeline and described second pipe by described sealing ring.
A better embodiment of the present utility model is that the outer wall of described inner connection tube is provided with o-ring groove, and described sealing ring is arranged in described o-ring groove.
A better embodiment of the present utility model is, the outer wall of described inner connection tube arranges at least one isolation convex tendon.
A better embodiment of the present utility model is, described first pipeline or/and the connecting portion reducing of second pipe and inner connection tube, the external diameter of described inner connection tube less than described first pipeline or/and the internal diameter of second pipe connecting portion and more than the internal diameter at other positions.Described inner connection tube inserts described first pipeline respectively or/and after connecting portion after described second pipe reducing, port will finally directly be against at the reducing of the first pipeline and/or second pipe.If the first pipeline and second pipe have a pipe reducing, another pipe is constant, then inner connection tube must set card muscle, and otherwise inner connection tube can swim the pipeline into non-reducing because of hydraulic pressure with water.In other words, if the first pipeline and second pipe all reducings, then two ends will directly be connected at the reducing of two pipelines, thus also will not shift migration because of inner pipe water pressure without card muscle inner connection tube.
Advantageous Effects of the present utility model includes: in the operating process using this assembling pipe joint, first described first connecting tube is inserted in one end of described inner connection tube, again the other end of described inner connection tube is inserted described second connecting tube, first pipeline and second pipe are docked and connected, described location hollow bolt is connected on described first pipeline chimb through described first pipeline, described location nut is threadeded through described second pipe with described location hollow bolt, described second pipe chimb is made to be connected in the screens of described location nut, thus be connected with described location nut thread by described location hollow bolt and described first pipeline chimb is axially positioned connected with described second pipe chimb, it is achieved thereby that without operations such as any installation tool and on-the-spot processing, the free-hand connection realized between pipeline.Wherein, use threadeding between location hollow bolt and described location nut, directly the first pipeline chimb and second pipe chimb are stuck between location hollow bolt and location nut, realize the axial location of the docking port of the first pipeline and second pipe, its attachment structure is simple, operation is simple, and structure is more stable.Secondly, it is respectively provided with sealing ring between outer wall and the inwall of the inwall of described first connecting tube and described second connecting tube of described inner connection tube, inner connection tube is inserted in the first connecting tube and the second connecting tube, realize being tightly connected of described inner connection tube and described first connecting tube and described second connecting tube by described sealing ring, and then achieve being docked and connected of the first pipeline and second pipe.3rd, isolation convex tendon is set in the middle part of the outer wall of described inner connection tube, the both sides of the isolation convex tendon that the mouth of pipe of the first pipeline and second pipe is connected to described inner connection tube respectively achieve a butt joint and described inner connection tube can be made to be positioned at the mouth of pipe of the first pipeline and second pipe owing to arranging isolation convex tendon, will not cause the migration of inner connection tube because of manifold pressure change.If when connecting the first pipeline and second pipe, when middle appearance need to lengthen the situation of pipeline, the inner connection tube of available longer dimension inserts in the first pipeline and second pipe, the two ends outer wall of described inner connection tube arranges and respectively sets an isolation convex tendon, the mouth of pipe of the first pipeline and the mouth of pipe of second pipe are connected to the outside of above-mentioned two isolation convex tendon respectively, thus realize lengthening the assembling of pipeline.4th, the direct reducing of pipeline, the screens respectively of the two ends of inner connection tube, at reducing, can make described inner connection tube will not cause the migration of inner connection tube because of manifold pressure change, make structure more stable.
To sum up, this utility model has that simple in construction, simple installation, cost of labor and maintenance cost be low, zero scrappage, can extend the beneficial effects such as duct length.
This utility model can be used for the connection of various metallic conduit and installs.
