SUMMERY OF THE UTILITY MODEL
To the above-mentioned weak point that exists among the prior art, the utility model aims at providing a hollow sucker rod reducer union of grease proofing effectual, simple to operate.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: hollow sucker rod reducing joint, including connecting, connect the top diameter and be greater than the sucker rod diameter, and with sucker rod diameter phase-match sets up, it is provided with the inflation post to connect the inner wall top, the inflation post with connect inner wall fixed connection, just the diameter of inflation post with connect diameter fixed connection, be provided with the opening on the inflation post, the opening is the setting of radius frustum shape structure, inflation toe portion is provided with grease proofing plastic, be provided with forward screw on the surface of joint bottom, it is less than to connect the bottom diameter sucker rod diameter, and with sucker rod diameter phase-match sets up, it is hexagonal nut shape structure setting to connect the middle part.
The top and the bottom of the joint are arranged in an up-down structure.
The material of the expansion column is a rubber expansion column.
And a spanner is arranged in the middle of the joint and matched with the hexagon nut-shaped structure.
And reverse threads are arranged on the inner wall of the sucker rod connected with the bottom end of the joint.
The forward thread is matched with the reverse thread.
The utility model has the advantages that: the oil-proof effect is good, the installation is convenient, the sucker rod connected with the bottom end is inserted into the top of the joint and is pressed by force, because the top end of the inner wall of the joint is provided with the expansion column which is fixedly connected with the inner wall of the joint and is provided with the opening which is arranged in an inverted frustum structure, therefore, the outer wall of the sucker rod can extrude the expansion column, the expansion column can generate resilience force to tightly clamp the sucker rod with the column, the gap is reduced in the traditional thread mode, oil leakage can be prevented, and then the sucker rod connected with the top end is connected through the forward thread to increase the stability of the structure, when pumping oil, oil can be pumped upwards from the sucker rod connected with the bottom end, when passing through the joint, the oil can be filled in the joint, the bottom of the expansion column is provided with oil-proof plastic, so can prevent that the oil from flowing out the joint, later the sucker rod that oil was connected through the top is taken out, greatly increased grease proofing effect.
