Abstract
The invention discloses a rotatable pipe joint. The rotatable pipe joint comprises a first connection sleeve and a second connection sleeve, and the first connection sleeve and the second connection sleeve are in relatively rotatable connection. The upper end face of the first connection sleeve is provided with an annular groove, a barrel used for being connected with the second connection sleeve is in threaded connection with the annular groove, an upper opening of the barrel is provided with an annular convex shoulder projecting inwards, a lower opening of the second connection sleeve is provided with an annular step projecting outwards, the annular step is arranged between the annular convex shoulder and the upper end face of the first connection sleeve, and each of the first connection sleeve and the second connection sleeve is internally provided with an internal thread used for connection with pipe fittings. The first connection sleeve and the second connection sleeve are capable of rotating relatively to realize free rotation of a pipe body, and accordingly torsional deformation of the pipe body can be avoided.
Description
Technical field
The present invention 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 be applied in the conveying of gas or liquid, but, on actual use, the group of general pipeline is established frequent need and is used pipe joint, completes the connection between tube and tube, therefore by the connection of pipe joint, the convenience that suitable pipe joint structure design concerns on using, and can meet the required function of Consumer.
The connection that general pipe joint is mainly common in water pipe is used, one end of this pipe joint is combined with water pipe, the other end is for engaging a use instrument (as grafting rapid pipe joint, nozzle or spray gun etc.), but, because this use instrument is to utilize the mode that screws togather interlocking to be combined on this pipe joint, between this use instrument and pipe joint, be stationary state and not rotatable, the user that wish changes use instrument to time, in the time that rotating, use instrument also can rotate body, make body produce torsional deflection, recessed folding or upset, and then affect flow rate of water flow and the hydraulic pressure in body, cause the unstable and puzzlement while use.
Summary of the invention
The object of the present invention is to provide a kind of rotatable pipe joint, solve pipe joint in prior art and cannot rotate the technical problem that is easily distorted and is out of shape while causing body to rotate.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is: a kind of rotatable pipe joint, comprise the first adapter sleeve and second adapter sleeve that can relatively rotate connection, on the upper-end surface of the first adapter sleeve, offer annular groove, in annular groove, be threaded connection and be useful on the core pipe that connects the second adapter sleeve, the upper orifice place of described core pipe is provided with the annular convex shoulder of inside protuberance, the lower nozzle place of described the second adapter sleeve is provided with the ring-shaped step of outwardly convex, ring-shaped step is placed between annular convex shoulder and the upper-end surface of the first adapter sleeve, the interior internal thread being also respectively equipped with for connection pipe fitting of the first adapter sleeve and the second adapter sleeve.
As a further improvement on the present invention, between the upper-end surface of described the first adapter sleeve and ring-shaped step, be provided with the first seal ring.
As preferred version of the present invention, described the first seal ring is carbon seal ring.
As a further improvement on the present invention, the upper-end surface of described core pipe is provided with some mounting holes for rotary core pipe.
As preferred version of the present invention, described mounting hole is hexagon.
As a further improvement on the present invention, the periphery of described the first adapter sleeve and the second adapter sleeve is also respectively equipped with rotation anti-slip veins.
As a further improvement on the present invention, the inwall of described the 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 a further improvement on the present invention, between described annular convex shoulder and ring-shaped step, be also provided with the 3rd seal ring.
The present invention, in when assembling, packs the first seal ring, the second adapter sleeve, the 3rd seal ring in the first adapter sleeve into successively, then core pipe is screwed in the first adapter sleeve, guarantees that the second adapter sleeve can rotate freely can come into operation.Compared with prior art, the beneficial effect that the present invention 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 anti-slip veins, be convenient to pipe fitting connection; On core pipe, be provided with mounting hole, be convenient to assembling and dismounting.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
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 anti-slip veins.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technological scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, rotatable pipe joint, on the upper-end surface of the first adapter sleeve 1, offer annular groove, in annular groove, be threaded connection and be useful on the core pipe 3 that connects the second adapter sleeve 2, the upper orifice place of core pipe 3 is provided with the annular convex shoulder 3a of inside 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 annular convex shoulder 3a and the upper-end surface of the first adapter sleeve 1, between ring-shaped step 2a and annular convex shoulder 3a, be also provided with the 3rd seal ring 6, between the upper-end surface of ring-shaped step 2a and the first adapter sleeve 1, be provided with the first seal ring 4, the good carbon seal ring of the first seal ring 4 preferred wear-resisting property.In the first adapter sleeve 1, be provided with internal thread, for connection pipe fitting, the inwall of the second adapter sleeve 2 offers the step hole extending 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, in the time that 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 anti-slip veins 1a, 2b, avoids in the time of connection pipe fitting, and skidding appears in the first adapter sleeve 1, the second adapter sleeve 2.
