Abstract
The utility model discloses a joint for the threaded connection of pipes in a machinery industry and aims at providing the joint which can wholly rotate with no loose of connected threads after connection. Both ends of the joint, namely, a first joint and a second joint, are respectively connected with respective outer pipes needing to be connected; devices which are locked with each other are arranged between the first joint and the second joint; the exterior of the second joint is sheathed with a movably connected and coaxial ring sleeve which is in the threaded connection with the first joint. The joint can realize the purpose that the joint can wholly rotate after the pipes are connected and the connected threads do not get loose. The joint is suitable for certain occasions with special requirements.
Description
Technical field
The utility model relates to the joint that a kind of pipe pipe thread of mechanical industry connects, and specifically, but is unitary rotation and the joint of the connecting thread that do not get loose after a kind of connection.
Background technique
In a lot of industries such as machinery, building, all can run into the connectivity problem between pipe and the pipe, usually the Placement that adopts is threaded, seizing type connects, be welded to connect etc., it respectively has pluses and minuses, seizing type is installed the most efficient and convenient, detachable recycling, but steadiness and sealing are all the poorest; Weld the most firm but the site operation inconvenience, can not do the dismounting recycling; Comparatively speaking, being threaded has the advantage of said two devices, therefore is most widely used in practice.The mode that generally is threaded, be to adopt nose end that supporting internal and external screw thread is set respectively at two butt tubes, be threaded by screwing between the pipe, therefore when a certain pipe be threaded together when a certain direction is rotated, opposite spin then can be unclamped screw thread.Allow two pipes after linking to each other can make unitary rotation if desired, can only rotate according to this direction that screw thread screws, two pipe threads after then might causing linking to each other well originally as opposite spin get loose.Yet can the not get loose joint categories of connecting thread of left-right rotation does not also appear can whole doing after a kind of connect in present stage.
Summary of the invention
The purpose of this utility model is in order to overcome deficiency of the prior art, but provides unitary rotation after a kind of connection and the joint of the connecting thread that do not get loose.
To achieve these goals, the technical solution of the utility model is:
But unitary rotation after a kind of connection and the joint of the connecting thread that do not get loose, the two ends of joint then need continuous outer tube I and outer tube II respectively, its middle external tube I links to each other with first joint, and outer tube II links to each other with second joint, is provided with sealed each other device between described first joint and second joint; The outside of described second joint is with a coaxial ring set that is movably connected, and described ring set and described first joint are to be threaded.
As further improvement of the utility model, described sealed each other device is concavo-convex plug in construction, is specially the female groove that outstanding public boss is set in the end of described first joint and depression is set in the relevant position of described second joint; When described ring set screw thread rotation, the described public boss that furthers embeds in described female groove.
As further improvement of the utility model, the quantity of described public boss and female groove is more than 1, is symmetrically distributed on the circumference separately.
As further improvement of the utility model, described second joint is provided with convex shoulder, is subjected to the restriction of the boss on the described ring set, and described second joint can not skid off described ring set in the other direction.
As further improvement of the utility model, described second joint is provided with the thickening piece that docks with outer tube.
The beneficial effects of the utility model are to realize that a kind of tube and tube can wholely be done to rotate arbitrarily and the pipe joint that can not get loose can be suitable in some occasion that specific (special) requirements is arranged after connection.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, joint of the present utility model comprise two can be sealed each other first joint 1 and second joint 3; The circumference outside of second joint 3 is with a coaxial ring set 2 that is movably connected, one end of ring set 2 is provided with internal thread 21, corresponding with the outside thread 11 on first joint, 1 circumference, the other end is provided with boss 22, by the convex shoulder 33 on second joint, 3 circumference, limit second joint 3 and can not skid off this ring set 2 backward; The end circumferencial direction of second joint 3 is provided with female groove 32 of depression, and the public boss 12 outstanding with first joint, 1 end is corresponding, locks the two during insertion and can only produce motion synchronously; The other end afterbody of second joint 3 is welded with the thickening piece 31 of annular, dock corresponding with the wall thickness of outer tube II5; The tail dimension of first joint 1 also with corresponding butt joint of outer tube I4 wall thickness.
As shown in Figure 3, Figure 4,2 public boss 12 to outer process are set symmetrically on the end circumference of first joint 1; As Fig. 5, shown in Figure 6, female groove 32 of 2 depressions also is set on the end circumference of second joint 3 accordingly, cooperate with public boss 12.
In Fig. 2, when the outside thread 11 of first joint 1 screwed with the internal thread 21 on the ring set 2, by only rotating ring set 2, first joint 1 that axially furthers was drawn close to second joint 3, and then makes public boss 12 can embed fully in female groove 32, locks the two and is synchronized with the movement.Like this, the no matter left-handed or dextrorotation of outer tube all can drive corresponding first joint 1 and second joint 3 and do synchronous rotation, and does not influence the cooperation between the screw thread 11 and 21 after originally connecting, finally realizes the purpose that the utility model is wanted.
At last, it should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
