Description
Affiliated technical field
The utility model relates to a kind of oil drilling tool, particularly a kind of oil drill rocker.
Background technology
Oil drill rocker is indispensable important tool in oil drilling operation, because the oil drilling degree of depth is generally darker, needs many drilling rods connection guarantees normally to creep into along with drilling depth increases.The mostly complicated structure of oil drill rocker using at present, it is very inconvenient to couple together, and connector easily lost efficacy, and is unfavorable for the raising of drillng operation efficiency.
Utility model content
The purpose of this utility model is the above-mentioned shortcoming for existing oil drill rocker, and a kind of oil drill rocker is provided, and connects inconvenience, the problem that connector easily lost efficacy in order to solve existing drilling rod.
The technical scheme adopting for the utility model that achieves the above object is: comprise butt joint, sleeve pipe, drilling rod body, docking slot, connection-peg, the fixing butt joint in one end of drilling rod body, the fixing connection-peg of the other end of drilling rod body, described butt joint is provided with butt joint shoulder, described connection-peg is provided with connection-peg shoulder, described butt joint shoulder and the outside of connection-peg shoulder are equipped with external screw thread, the outside of described butt joint shoulder is threaded connection sleeve pipe, the outside of described connection-peg shoulder is provided with the sleeve pipe shoulder of limiting boot activity, the inside of described connection-peg is provided with docking slot.
The end of above-mentioned connection-peg shoulder is provided with sealing ring.
Above-mentioned sleeve pipe and sleeve pipe shoulder, butt joint shoulder pass through threaded engagement.
The beneficial effects of the utility model are, the jackrod structure of the utility model design is simple, easy to connect, and abrasion resistance is extremely strong, can extend the application life of drilling rod.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is three-dimensional structure schematic diagram of the present utility model.
Fig. 3 is the syndeton schematic diagram between oil drill rocker.
In the drawings, 1. butt joint, 2. butt joint shoulder, 3. sleeve pipe, 4. drilling rod body, 5. sleeve pipe shoulder, 6. connection-peg shoulder, 7. sealing ring, 8. docking slot, 9. connection-peg.
Detailed description of the invention
1-3 by reference to the accompanying drawings, is described further the utility model:
The utility model comprises butt joint 1, sleeve pipe 3, drilling rod body 4, docking slot 8, connection-peg 9, the fixing butt joint 1 in one end of drilling rod body 4, the fixing connection-peg 9 of the other end of drilling rod body 4, described butt joint 1 is provided with butt joint shoulder 2, described connection-peg 9 is provided with connection-peg shoulder 6, described butt joint shoulder 2 and the outside of connection-peg shoulder 6 are equipped with external screw thread, the outside of described butt joint shoulder 2 is threaded connection sleeve pipe 3, the outside of described connection-peg shoulder 6 is provided with the sleeve pipe shoulder 5 of limiting boot 3 activities, the inside of described connection-peg 9 is provided with docking slot 8.
Wherein, the end of connection-peg shoulder 6 is provided with sealing ring 7, and sealing ring 7 can seal two gaps between drilling rod, prevents fluid seepage.
In addition, sleeve pipe 3 is with sleeve pipe shoulder 5, butt joint shoulder 2 by threaded engagement, and sleeve pipe 3 works to connect two adjacent drill pipes.
Described sleeve pipe 3 and sleeve pipe shoulder 5 are made by high-abrasive material, sleeve pipe shoulder 5 mainly plays the role of positioning to sleeve pipe, in the time that two drilling rods dock, the butt joint 1 of upper drilling rod is inserted in the docking slot 8 of lower drilling rod, and rotating casing 3 matches with sleeve pipe shoulder 5 until sleeve pipe 3 arrives, thereby complete the docking of two drilling rods, it is simple, convenient to connect, and connector is not easy to lose efficacy, and is conducive to the raising of drillng operation efficiency.
