As another preferred scheme of the utility model, the connector comprises a connecting block, both ends of the connecting block are provided with hemispherical grooves, and rectangular plugs are arranged in the hemispherical grooves; the end part of the guide shaft is a sphere matched with the hemispherical groove, and a rectangular groove matched with the rectangular plug is formed in the sphere.
As a third preferred aspect of the present invention, the joint is provided with an anti-eccentric sleeve outside, and a gap is also provided between the anti-eccentric sleeve and the joint.
The utility model has the advantages that: 1. the utility model discloses be provided with the clearance between barrel and connector and guiding axle, can have the rotation that reduces the barrel by a wide margin to prevent that barrel and oil pipe from producing eccentric wear phenomenon, improving the utility model discloses and oil pipe's life, the operation is reliable and stable.
2. The utility model provides a two kinds of connector structures, it is different according to the demand, the different connector form of optional usefulness, strong adaptability is fit for old equipment transformation, reduces equipment cost.
3. The utility model discloses set up the eccentric wear prevention cover outside connecting, can prevent effectively that joint and oil pipe from producing the eccentric wear phenomenon, further improve the utility model discloses an eccentric wear prevention effect.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of another embodiment of the present invention.
In the attached drawing, 1 is a guide shaft, 2 is a taper hole, 3 is a sphere, 4 is a rectangular plug, 5 is a gap, 6 is a rectangular hole, 7 is a connecting sleeve, 8 is a hemispherical groove, 9 is a positioning groove, 10 is a positioning sleeve, 11 is an anti-eccentric sleeve, 12 is a joint, 13 is a connecting block, and 14 is a cylinder.
Detailed Description
The utility model discloses a barrel 14, both ends all are provided with guiding axle 1 in the barrel 14, and 1 tip of two guiding axles is provided with joint 12, is provided with connector, its characterized in that between two guiding axles 1: a gap 5 is provided between the cylinder 14 and the connector and the guide shaft 1.
As a preferred scheme of the utility model, the connector comprises a connecting sleeve 7, two ends of the connecting sleeve 7 are provided with hemispherical grooves 8, and rectangular holes 6 are arranged in the hemispherical grooves 8; the end part of the guide shaft 1 is a sphere 3 matched with the semispherical groove 8, and a rectangular plug 4 matched with the rectangular hole 6 is arranged on the sphere 3.
As another preferred scheme of the utility model, the connector comprises a connecting block 13, both ends of the connecting block 13 are provided with hemispherical grooves 8, and rectangular plugs 4 are arranged in the hemispherical grooves 8; the end part of the guide shaft 1 is a sphere 3 matched with the semispherical groove 8, and the sphere 3 is provided with a rectangular groove matched with the rectangular plug 4.
As a third preferred aspect of the present invention, the joint 12 is externally provided with an anti-eccentric sleeve 11, and a gap 5 is also provided between the anti-eccentric sleeve 11 and the joint 12.
And two ends of the cylinder body 14 are provided with positioning sleeves 10, and the positioning sleeves 10 are provided with positioning grooves 9 matched with the spheres 3 of the guide shaft 1.
A taper hole 2 is arranged in the positioning sleeve 10 corresponding to the guide shaft 1.
The taper hole 2 enables an included angle of 7 degrees at most to be formed between the central line of the guide shaft 1 and the central line of the cylinder 14.
When the utility model is used, the joints 12 at the two ends of the utility model are respectively connected with two sucker rods, one sucker rod rotates, and the other sucker rod rotates under the drive of the guide shaft 1 and the connector; in the working process, because the gaps 5 exist among the cylinder 14, the connector and the guide shaft 1, when the cylinder 14 is subjected to resistance, the guide shaft 1 and the connector can idle automatically, the cylinder 14 does not rotate, and the eccentric wear at the cylinder 14 is prevented.
Similarly, because the anti-eccentric sleeve 11 is arranged outside the joint 12, when the anti-eccentric sleeve 11 is subjected to resistance, the joint 12 can idle, the anti-eccentric sleeve 11 does not rotate, and eccentric wear occurs at the joint 12.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
