Nuts are screwed tightly on the external threads inlaid in the press tongues on both of the two ends of the barrel body. When the utility model is used, the utility model is inserted into the connecting pipe from the end part of the barrel body, the splints are sheathed, the press tongues are turned and pressed into the gaps, and the nuts on the end part of the barrel body are screwed firmly. The utility model is convenient for assembly and disassembly, and the pipe self does not need to preprocess. The use is convenient.

Description

The detachable mounted pipe coupling

The utility model relates to a kind of assembling pipe joint, particularly a kind of detachable mounted pipe coupling.

How existing pipe coupling is respectively equipped with internal and external threads at two connecting ends of pipeline, with the mutual interlock of internal and external threads, pipeline is fused; Perhaps, outwards curve circular flange plate, on flange plate, bore a hole again, connect together with bolt with connecting end; These connection sets are processed thread cutting in advance because pipe must be connect itself, or are made flange plate in advance, use a plurality of bolt again, so cumbersome, especially when pipeline is longer, process more inconvenient, and when connecting, aim at the mouth of pipe, threaded together or difference construction bolt are also relatively taken a lot of work.

The purpose of this utility model is that a kind of detachable mounted pipe coupling will be provided, its easy accessibility, and pipeline itself does not need to process in advance, easy to use.

The purpose of this utility model is achieved in that this detachable mounted pipe coupling becomes semicircular metal splint to be constituted by the plastic cylinder peace treaty, the two ends of cylindrical shell are provided with gap, with outside thread to outer process, clamping plate are fastened on from both sides on the cylindrical shell between the outside thread, two clamping plate ends are provided with earrings and pass earrings with screw, be hinged on the pressure tongue that also can embed in the earrings in the gap, nut screwing clamping is on the outside thread of cylindrical shell two ends wedge pressure tongue, during use, insert connecting pipeline earlier from the cylindrical shell end, the cover punch holder will be pressed tongue to rotate and be laid, be pressed in the gap, tighten the cylindrical shell end nut and get final product.

The utility model advantage is to need only the accurately good this pipe coupling that matches with pipeline, and the connecting tube body need not be processed in advance, thus the energy parallel operations, improve work efficiency, dismounting is rapid, convenient, and in addition, this joint also can be used in the connection work of solid barred body.

The utility model concrete structure is provided by following examples and accompanying drawing thereof.

Describe in detail below in conjunction with accompanying drawing.

With reference to Fig. 1,2,3,4, this detachable mounted pipe coupling is made of the metal splint 2 of plastic cylinder 1 and two about semicirculars in shape, the two ends of cylindrical shell 1 are provided with gap 6, with outside thread 7 to outer process, clamping plate 2 are fastened between cylindrical shell 1 outside screw 7 from both sides, be provided with earrings 12 in two clamping plate, 2 joints and pass earrings 12 with screw 5 and be hinged in the earrings and can embed pressure tongue 3 in the gap 6, nut 4 is tightened on the outside thread 7 at cylindrical shell 1 two ends of wedge pressure tongue 3.Joint can be sector, and T font or other polygon are provided with the step 8 that stops external pipe 9 to continue insertion on the inwall of cylindrical shell 1.Press the bottom of tongue 3 and clamping plate 2 connecting ends, be provided with the corner angle 10 that inwardly protruding also can snap in the tube wall of external pipe 9.The joint that clamping plate are 2 is provided with and makes two plates hold out against close merging into to press tongue 3 to reserve the tongue and groove 11 that rotates leeway.

When the utility model uses, earlier nut 4 is unclamped from connecting end and take off, with pressure tongue 3 perks that are connected on the clamping plate 2, pipeline to be connected 9 ends that external diameter is matched with cylindrical shell 1 internal diameter are inserted in the cylindrical shell 1 and are withstood on the step 8, then the pressure tongue 3 of clamping plate 2 ends is turned down, enter in the gap 6, be screwed into nut 4 subsequently, owing to press tongue 3 afterbodys to be provided with corner angle 10, nut 9 is more twisted tighter, thereby external pipe 9 is fixed in the pipe coupling firmly, closely connected because of plastic cylinder 1 and external pipe 9 again, so can reach seal action.

When external pipe 9 diameters are big, remove in vertical joint of two clamping plate 2, be provided with corresponding gap 6 and press outside the tongue 3, also can joint laterally, left and rightly respectively set up a cover gap and press tongue, in the hope of reaching more firmly purpose of connecting, as shown in Figure 3.

With reference to Fig. 5, the metal splint of two semicirculars in shape that the utility model uses also can cylindrical shape have gap and press a cage plate 13 of tongue to replace, used cylindrical shell can have externally threaded barrel head 14 with an end, so that the better requirement of satisfying the multidirectional pipeline of connection.
