Abstract
The utility model relates to a sucker rod anticreep rotary joint. The present oil field beam -pumping unit of main solution moves the back rod connector for a long time and easily takes place the not hard up problem of dropout even. Its characterized in that: top connection (1) bottom threaded connection has overcoat (2), and it has pivot (3) to deploy in overcoat (2) to be equipped with bearing (4) between overcoat and pivot (3), pivot (3) lower extreme passes overcoat (2) backs its end connection lower clutch (5). This sucker rod anticreep rotary joint can avoid the sucker rod to take place radial the rotation to avoid connecting the dropout and take place the pole phenomenon.
Description
Technical field
The utility model relates to oilfield, specifically a kind of sucker rod anticreep swivel joint.
Background technology
On current oil field, oil pumper is subject to the impact of hole deviation when rising and taking out, easily form radial rotating, after such oil pumper long-play, rod connector easily loosens, and joint can be caused time serious to thread off, fall bar phenomenon, affect production efficiency, increase cost of production.
Summary of the invention
In order to rod connector after overcoming existing oil pumping in oil fields long-play easily occurs to loosen the deficiency of even threading off, the utility model provides a kind of sucker rod anticreep swivel joint, this sucker rod anticreep swivel joint can avoid sucker rod generation radial rotating, thus avoids joint thread off and fall bar phenomenon.
The technical solution of the utility model is: a kind of sucker rod anticreep swivel joint, comprise top connection, lower contact, described top connection bottom thread is connected with overcoat, and jacket internal is equipped with rotating shaft, and be provided with bearing between overcoat and rotating shaft, described rotating shaft lower end connects lower contact through its end after overcoat.
Described top connection top is provided with oil tube external thread, and lower contact bottom is provided with oil pipe internal thread.
The utility model has following beneficial effect: owing to taking such scheme, be provided with bearing between overcoat and rotating shaft, makes it rotatable each other, thus makes can mutually rotate between upper-lower section sucker rod.Such sucker rod is when operation is subject to Well Deflection Influence up and down, and radial direction can be rotated voluntarily, thus avoids joint dropout and cause bar phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-top connection in figure, 2-overcoat, 3-rotating shaft, 4-bearing, 5-lower contact.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of sucker rod anticreep swivel joint, comprises top connection 1, lower contact 5, and described top connection 1 top is provided with short circuit, and lower contact 5 bottom is also provided with short circuit, makes it can connecting with pumping rod.Described top connection 1 bottom thread is connected with overcoat 2, and overcoat 2 inside is equipped with rotating shaft 3, and is provided with bearing 4 between overcoat and rotating shaft 3, makes can mutually rotate between overcoat 2 and rotating shaft 3, and described rotating shaft 3 lower end connects lower contact 5 through its end after overcoat 2.Due to rotatable between overcoat 2 and rotating shaft 3, make can mutually rotate between the sucker rod of the sucker rod on top connection 1 top and lower contact 5 bottom, thus rod connector can be avoided to thread off.
Bearing 4, when assembling, is first put into overcoat 2 by this sucker rod anticreep swivel joint, then rotating shaft 3 is inserted by overcoat 2 top, is then connected with top connection 1 and lower contact 5 respectively by overcoat 2.In use, by top connection 1, lower contact 5, sucker rod is connected, can pump.When sucker rod moves up and down oil pumping, if be subject to the impact of hole deviation, between upper-lower section sucker rod, there is the trend of relative radial rotating, at this moment can mutually rotate between overcoat 2 and rotating shaft 3, thus relatively rotate between drive upper-lower section sucker rod, avoid rod connector and thread off.
Claims (2)
1. a sucker rod anticreep swivel joint, comprise top connection (1), lower contact (5), it is characterized in that: described top connection (1) bottom thread is connected with overcoat (2), overcoat (2) inside is equipped with rotating shaft (3), and be provided with bearing (4) between overcoat and rotating shaft (3), described rotating shaft (3) lower end connects lower contact (5) in its end afterwards through overcoat (2).
2. sucker rod anticreep swivel joint according to claim 1, it is characterized in that: described top connection (1) top is provided with oil tube external thread, lower contact (5) bottom is provided with oil pipe internal thread.
