Abstract
The utility model is related to the oil rig in oil equipment, specifically a kind of coiled rod, including the body of rod, and the body of rod is provided with some boss, and jointing is provided with the end of the body of rod, and the joint is connected with the body of rod by box cupling；The box cupling is the body for being socketed in rod end；The boss both sides of the rod end are provided with slips and spacing ring；Described box cupling one end is connected provided with spacing interior step with slips；The other end of the box cupling is connected by pipe internal thread with joint.This programme is rational in infrastructure simple, and improving the bonding strength of beam hanger also has the advantages that small volume, reduces the collision to oil pipe in use.
Description
Technical field
The utility model is related to the oil rig in oil equipment, specifically a kind of coiled rod.
Background technology
At present, the pumping rod made by steel generally used in oil field is recovered the oil, and it is taking out for without screw thread connection that sucker rod is a kind of
Beam hanger, another is the common beam hanger of screwed connection.The anticorrosion antiwear measure that current coiled rod is mainly taken is in the body of rod
Interior addition metallic element, and body of rod surface is heat-treated, and phenomenon in occurring two in：1 is that body of rod surface is hard
Degree is high worn out by oil pipe, and oil well can not be produced normally, and 2 be that body of rod surface is corroded, and influences the use of bar.What is used now carries
The coiled rod of screwed connection, the box cupling in junction is relatively large in diameter, and the oil pipe on periphery is easily collided in use, because
And its life-span substantially reduces.Therefore need to be improved junction, reduce gouging abrasion.
The content of the invention
It is to solve the problem of prior art is present that the utility model, which is exactly, and devises a kind of coiled rod, and structure is closed
Reason is simple, and improving the bonding strength of beam hanger also has the advantages that small volume, reduces the collision to oil pipe in use.
The technical solution of the utility model is：A kind of coiled rod, including the body of rod, the body of rod are provided with some boss,
The end of the body of rod is provided with jointing, and the joint is connected with the body of rod by box cupling；The box cupling is to be socketed in body of rod end
The body in portion；The boss both sides of the rod end are provided with slips and spacing ring；Described box cupling one end provided with spacing interior step with
Slips is connected；The other end of the box cupling is connected by pipe internal thread with joint.
The plug for fixed core is provided with the box cupling.
The plug is with externally threaded dormant bolt.
The dormant bolt is interior hexagonal dormant bolt.
The body of rod of the sucker rod is elliptic cross-section.
The beneficial effects of the utility model can be drawn by such scheme：The connected mode simple and stable of this programme, box cupling
Diameter is small, using can significantly reduce the collision to tubing wall in oil pipe, improves the use time of beam hanger, reduces loss,
With positive effect.
As can be seen here, the utility model has substantive distinguishing features and progress compared with prior art, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Wherein, 1 is joint, and 2 be box cupling, and 3 be plug, and 4 be spacing ring, and 5 be slips, and 6 be spacing interior step, and 7 be the body of rod.
Embodiment：
In order to more fully understand the utility model, embodiment of the present utility model is explained in detail below in conjunction with the accompanying drawings.
Embodiment：As shown in figure 1, a kind of coiled rod, including the body of rod 7, the body of rod 7 of sucker rod is ellipse
Section, the body of rod 7 is provided with some boss, and jointing 1 is provided with the end of the body of rod 7, and the joint 1 passes through box cupling 2 with the body of rod 7
It is connected；The box cupling 2 is the body for being socketed in the end of the body of rod 7；The boss both sides of the end of the body of rod 7 provided with slips 5 and
Spacing ring 4；Described one end of box cupling 2 is connected provided with spacing interior step 6 with slips 5；The other end of the box cupling 2 passes through in pipe
Screw thread is connected with joint.The plug 3 for fixed core 7 is provided with the box cupling 2.The plug 3 is with externally threaded interior
Hexagonal dormant bolt.
Described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
