Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of rotatable pipe joint.
Background technique
Pipeline in daily life is mainly used for carrying fluid, as being applied in the conveying of gas or liquid, but, in actual use, the group of general pipeline is established and often need be used pipe joint, is completed the connection between tube and tube, therefore by the connection of pipe joint, the convenience that suitable pipe joint structure design concerns in use, and the function needed for Consumer can be met.
The connection that general pipe joint is mainly common in water pipe uses, one end of this pipe joint is combined with water pipe, the other end is then for engaging a use instrument (as grafting rapid pipe joint, nozzle or spray gun etc.), but, because this use instrument utilizes the mode screwing togather interlocking to be combined on this pipe joint, not rotatable in stationary state between this use instrument and pipe joint, for the user that changes use instrument to time, also body can be rotated while use tool into rotation, body is made to produce torsional deflection, recessed folding or upset, and then the flow rate of water flow affected in body and hydraulic pressure, instability when causing use and puzzlement.
Model utility content
The purpose of this utility model is to provide a kind of rotatable pipe joint, solves pipe joint in prior art and cannot rotate the technical problem of being out of shape that to be easily distorted when causing body to rotate.
For reaching above-mentioned purpose, the technological scheme that the utility model adopts is: a kind of rotatable pipe joint, comprise first adapter sleeve and the second adapter sleeve that can relatively rotate connection, the upper-end surface of the first adapter sleeve offers annular groove, the core pipe for connecting the second adapter sleeve is threaded connection in annular groove, the upper orifice place of described core pipe is provided with the annular convex shoulder of inwardly protuberance, the lower nozzle place of described second adapter sleeve is provided with the ring-shaped step of outwardly convex, ring-shaped step is placed between the upper-end surface of annular convex shoulder and the first adapter sleeve, the interior internal thread be also respectively equipped with for connection pipe fitting of the first adapter sleeve and the second adapter sleeve.
As further improvement of the utility model, between the upper-end surface of described first adapter sleeve and ring-shaped step, be provided with the first seal ring.
As preferred version of the present utility model, described first seal ring is carbon seal ring.
As further improvement of the utility model, the upper-end surface of described core pipe is provided with some mounting holes for rotary core pipe.
As preferred version of the present utility model, described mounting hole is hexagon.
As further improvement of the utility model, the periphery of described first adapter sleeve and the second adapter sleeve is also respectively equipped with rotation grip line.
As further improvement of the utility model, the inwall of described second adapter sleeve also offers step hole, and the internal thread of the second adapter sleeve is located on the hole wall of step hole, and the bottom of step hole is also provided with the second seal ring.
As further improvement of the utility model, between described annular convex shoulder and ring-shaped step, be also provided with the 3rd seal ring.
The utility model is when assembling, and load in the first adapter sleeve by the first seal ring, the second adapter sleeve, the 3rd seal ring successively, then screwed in the first adapter sleeve by core pipe, guaranteeing that the second adapter sleeve can rotate freely can come into operation.Compared with prior art, the beneficial effect that the utility model reaches is: the first adapter sleeve and the second adapter sleeve can relatively rotate, and realize body and freely rotate, and avoid body torsional deflection; Be provided with multiple-sealed circle, avoid fed sheet of a media to leak; Be provided with rotation grip line, be convenient to pipe fitting connection; Core pipe is provided with mounting hole, is convenient to assembling and dismounting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, the first adapter sleeve; 2, the second adapter sleeve; 2a, ring-shaped step; 3, core pipe; 3a, annular convex shoulder; 3b, mounting hole; 4, the first seal ring; 5, the second seal ring; 6, the 3rd seal ring; 1a, 2b, rotation grip line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, rotatable pipe joint, the upper-end surface of the first adapter sleeve 1 offers annular groove, the core pipe 3 for connecting the second adapter sleeve 2 is threaded connection in annular groove, the upper orifice place of core pipe 3 is provided with the annular convex shoulder 3a of inwardly protuberance, the lower nozzle place of the second adapter sleeve 2 is provided with the ring-shaped step 2a of outwardly convex, ring-shaped step 2a is placed between the upper-end surface of annular convex shoulder 3a and the first adapter sleeve 1, the 3rd seal ring 6 is also provided with between ring-shaped step 2a and annular convex shoulder 3a, the first seal ring 4 is provided with between the upper-end surface of ring-shaped step 2a and the first adapter sleeve 1, the preferably good carbon seal ring of wear-resisting property of first seal ring 4.Internal thread is provided with in first adapter sleeve 1, for connection pipe fitting, the inwall of the second adapter sleeve 2 offers the step hole extended from the top down, the hole wall of step hole is provided with the internal thread for connection pipe fitting, the bottom of step hole is also provided with the second seal ring 5, when pipe fitting rotates to the end, pipe port is resisted against on the second seal ring 5, can realize the sealing of pipe fitting and the second adapter sleeve 2.For the ease of assembling and dismounting, the upper orifice place of core pipe 3 is provided with some mounting hole 3b for rotary core pipe 3, and mounting hole 3b is hexagon.The periphery of the first adapter sleeve 1 and the second adapter sleeve 2 is also respectively equipped with rotation grip line 1a, 2b, avoids when connection pipe fitting, and skidding appears in the first adapter sleeve 1, second adapter sleeve 2.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
