Abstract

The utility model relates to a pipeline connecting structure, which comprises a pipe joint (1) and a pipeline (2), wherein the pipe joint (1) is composed of a sleeve end connecting head (3) provided with a sleeve hole (4), and an insertion connecting head (6) provided with an inserting end (5). The inserting end (5) is arranged in the sleeve hole (4), and a sealing ring (7) is arranged between the inserting end (5) and the sleeve hole (4) to form a movable connecting head which can rotate by winding an axial line. A stop screw (8) preventing the insertion connecting head to conduct axial movement corresponding to the sleeve end connecting head is arranged in a radical screw hole of the side part of the sleeve hole (4) of the sleeve end connecting head (3). The connecting end of the pipeline (2) is provided with an inner thread (9), and the connecting end of the pipe joint (2) is provided with a corresponding outer thread (10). The utility model does not need fittings and can be directly connected with a metal pipe, a nylon pipe, a soft pipe and other pipelines. The utility model can guarantee connecting strength. The utility model has the advantages of reliable connection and seal, no water and gas leakage, convenient operation, low cost and repeated use.

Description

Simple and easy pipe connecting structure

Technical field

The utility model relates to pipe connecting structure.

Background technique

Pipeline connects and to need pipe joint, and that pipe joint has usually is straight-through, threeway, elbow and Duo Tong.Most pipe joints need locknut or locknut and cutting ferrule or the supporting use of hose clip; Though existing quick coupling is connecting leg directly, insufficient strength, and should not be used for the water route.Mother's with lock pipe joint generally is used for connecting nylon tube, is enclosed within on the pipe after needing during connection earlier locknut is unloaded, and pipe is inserted on the fuse of pipe joint, tightens locknut then and finishes connection; The pipe joint of mother with lock and cutting ferrule generally is used for being connected metal tube (when being used for connecting nylon tube, need in the metal-cored insertion nylon tube of cast in addition), earlier locknut is unloaded during connection, be enclosed within locknut and cutting ferrule on the pipe successively then, tighten locknut, locknut extruding cutting ferrule makes the cutting ferrule distortion fix pipe and realizes connecting; The pipe joint that connects flexible pipe, in use with hose proof on joint, come the fastening connection of finishing with hose clip then.The pipe joint of these band accessories can be applicable to being connected of water route and gas path pipe, can guarantee water-tight, air tight, but cutting ferrule and hose clip are the loss product, and cutting ferrule is normally disposable, in actual applications, fittings lost or damage often make pipe joint go out of use, and can cause waste like this.At present, the pipe joint on the market is compatible bad to pipe, does not have a kind ofly can connect metal tube, can connect the pipe joint of nylon tube and flexible pipe again.

The model utility content

The technical problems to be solved in the utility model is, defective at prior art exists designs a kind of simple and easy pipe connecting structure, and it does not need accessory, can directly connect metal tube, nylon tube, flexible pipe and other pipeline, its join strength and sealability are reliable, easy to operate, cost is low.

Technical solution of the present utility model is, described simple and easy pipe connecting structure comprises pipe joint and pipeline, its structural feature is, described pipe joint is by the cover end connecting head that is provided with trepanning and be provided with the connecting head that patches that patches end and form, the described end that patches places described trepanning and is provided with seal ring between the two and form can be around the flexible connection head of rotational, radially be provided with in the screw to stop at the trepanning sidepiece of cover end connecting head and patch connecting head and overlap the end connecting head relatively and make axially movable lock screw, the connecting end of described pipeline is provided with internal thread and the connecting end of pipe joint is provided with corresponding outside thread.

Below the utility model made further specify.

Referring to Fig. 1, the utility model has pipe joint 1 and pipeline 2, its structural feature is, described pipe joint 1 is by the cover end connecting head 3 that is provided with trepanning 4 and be provided with the connecting head 6 that patches that patches end 5 and form, the described end 5 that patches places described trepanning 4 and is provided with seal ring 7 between the two and form can be around the flexible connection head of rotational, radially be provided with in the screw to stop at trepanning 4 sidepieces of cover end connecting head 3 and patch connecting head and overlap the end connecting head relatively and make axially movable lock screw 8, the connecting end of described pipeline 2 is provided with internal thread 9 and the connecting end of pipe joint 2 is provided with corresponding outside thread 10.

In order to satisfy different needs and the simplified structures of using, can and patch connecting head 6 with the cover end connecting head in the structure shown in Figure 13 and make overall structure, promptly make overall structure as shown in Figure 2.

Prior art structural types such as the utility model pipe joint comprises straight-through (as Fig. 1 or shown in Figure 2), threeway, elbow, many logical, valves.

Design principle of the present utility model and connecting means are, because the internal diameter of existing pipes connector interface is identical with the external diameter of pipeline (pipe), it is standard measure, if any φ 6, φ 8, φ 10 or the like, pipeline connecting end are inserted in the described interface and have aforementioned disadvantages, and the external diameter of the utility model connecting head interface after the improvement is set according to actual needs; The general about 1.2mm of pipeline wall thickness, φ 6 so, and φ 8, and the internal diameter of the pipeline of φ 10 is about φ 3.5, φ 5.5, and φ 7.5, in the time of connection, earlier along the mouth of pipe toward the pipe internal tapping, the internal thread of tapping and interface kit is screwed to pipe joint in the pipe (or be enclosed within interface on pipe) then and gets final product.If metal tube, the pipe joint jointing need twine an amount of raw meal belt; If nylon tube or flexible pipe, because tapping process mill sassafras gives birth to heat, can make pipe that certain expansion is arranged, rapidly pipe joint is screwed in the pipe after having attacked thread, after cooling, pipe and pipe joint just can connect together securely, and Placement is referring to Fig. 1; Consider that there is certain difficulty (long pipeline rotation inconvenience) in pipe connecting structure when connecting many long tubes, ad hocly counted straight-through that two interfaces shown in Figure 1 (i.e. cover end connecting head 3 and patch the interface of connecting head 6) can rotate.Integrated pipe joint shown in Figure 2 is suitable for having only at most an end to connect than long pipeline or uses when being connected to fixed component, and rotating pipe joint gets final product during connection.

As known from the above, the utility model is a kind of simple and easy pipe connecting structure, and it does not need accessory, can directly connect metal tube, nylon tube, flexible pipe and other pipeline, can guarantee join strength and connect reliable and water-tight, the gas of sealing, easy to operate, cost is low, and can repeatedly use repeatedly.
