Abstract
The invention discloses a sucker rod connector which is provided with a body. Connecting openings are formed in two ends of the body. Inner threads are arranged in the connecting openings. The body is made of allow steel. Plastic sealing rings are respectively arranged on the connecting openings. The plastic sealing rings are fixed with the connecting openings in a pressing mode. The surface of each plastic sealing ring is provided with a wear-resistant coating. The wear-resistant coatings are made of powder alloy. The sucker rod connector has the advantages of being simple in structure, good in fixing effect, high in compressive strength and capable of adapting to technical requirements of oil drilling industry.
Description
Technical field
The present invention relates to the oil drilling field, refer more particularly to a kind of apparatus for connecting with pumping rod.
Background technology
In the process of oil drilling, need to use the sucker rod conveying crude oil, the purposes of sucker rod connector just is to be fixedly connected with sucker rod, in the process of down-hole oil production, when running into the generation skew of oil well and the earth's core, sucker rod is received crooked moment of torsion, thereby causes rod sag, produces pogo stick, sucker rod connector is fixed in sucker rod end, can play the effect of alleviating distortion, so sucker rod connector need to reach good fixing effect, the high requirement of compressive strength.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good fixing effect, sucker rod connector that compressive strength is high.
In order to solve the problems of the technologies described above, the invention provides a kind of sucker rod connector, be provided with main body, described main body two ends are provided with connector, and described connector is provided with internal thread, and described connector one end is provided with the plastics seal, described plastics seal adopts pressure injection mode and connector to fix, the outer cocke-stair shape tooth that is arranged with of described main body, the trapezoidal number of teeth amount of described spiral are 4-8, and the spiral stepped tooth is uniformly distributed in the main body periphery; Described main body adopts alloy steel material to make.
As a further improvement on the present invention, described main body one end is provided with recess, and described recess is used for spanner loading and unloading sucker rod connector.
As a further improvement on the present invention, described plastics seal surface is provided with wear-resistant coating, and described wear-resistant coating is powder metallurgy.
Adopt said structure, its beneficial effect is: described main body adopts alloy steel to make, and can improve the compressive strength of sucker rod connector, extends its application life; Described connector is provided with the plastics seal, and described plastics seal is to adopt pressure injection mode and connector to fix, and the plastics seal can make avoids hard collision and friction between sucker rod and sucker rod connector, guaranteed safety; The effects such as the outer cocke-stair shape tooth that is arranged with of described main body, the trapezoidal number of teeth amount of described spiral are 4-8, and are uniformly distributed in the main body periphery, and described spiral stepped tooth can play guiding, reduce friction; Described plastics seal surface is provided with wear-resistant coating, and described wear-resistant coating is powder metallurgy, and described wear-resistant coating has improved the anti-wear performance of plastics seal, extends its application life.
Description of drawings
