Abstract
A quick butt joint structure of an oil rod is characterized in that a butt joint body A and a butt joint body B are connected through threads, and the middle of the butt joint body A and the middle of the butt joint body B are sealed by a sealing ring B; the butt joint body A and the butt joint body B are respectively provided with an inserting rod end, and a through hole on the inserting rod end is provided with a sealing ring A; the butt joint body A and the butt joint body B are fixedly connected with symmetrical blocking bodies on two sides of a through hole, steel balls are placed in spaces between the blocking bodies, the steel balls are supported by springs, the butt joint body A and the butt joint body B are respectively inserted into two butted oil rods, then butt joint is carried out, thread fixing is carried out, the oil rods are butted and contacted, sealing is carried out through a sealing ring, the thread fixing is carried out, the oil rods cannot move, and the two rods are butted in the process of extrusion propulsion under the action of the steel balls and the springs. This structure can realize pegging graft fast, through accurate concentric counterpoint, reaches sealedly, and the installation operation during convenient construction is convenient to be dismantled simultaneously.
Description
Technical Field
The utility model belongs to the technical field of the oil recovery construction equipment, concretely relates to quick butt-joint structural of beam hanger.
Background
Oil pipe is the oil pumping when being used for oil recovery, and oil pipe of oil recovery of degree of depth is not enough to satisfy the demand, needs many oil poles butt joints, and present oil pipe connects most of adoption traditional API threaded connection, because structural design's reason, a lot of problems often appear in the tradition joint, chooses for use trapezoidal threaded connection leakproofness not to go, chooses for use circular threaded connection intensity lower.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a quick butt joint structure of an oil rod, which has quick butt joint and good sealing.
In order to realize the purpose, the utility model discloses a technical scheme is:
a quick butt joint structure of an oil rod comprises a butt joint body A (1) and a butt joint body B (2), and is characterized in that the butt joint body A (1) and the butt joint body B (2) are connected through threads (9), and the middle of the butt joint body A and the butt joint body B is sealed by a sealing ring B (8); the butt joint body A (1) and the butt joint body B (2) are respectively provided with an inserting rod end (3), and a through hole on the inserting rod end is provided with a sealing ring A (7); symmetrical blocking bodies (4) are fixedly connected to two sides of a through hole in the butt joint body A (1) and the butt joint body B (2), a steel ball (5) is placed in a space between the blocking bodies (4), and the steel ball (5) is supported by a spring (6).
The two sides of the through hole in the butt joint body A (1) and the through hole in the butt joint body B (2) are connected with symmetrical blocking bodies (4) through welding.
The pushing structure is composed of the blocking body (4), the steel ball (5) and the spring (6), 4 groups can be fixedly connected in the butt joint body A (1) and the butt joint body B (2) and are arranged according to four symmetrical positions, and two groups are also symmetrically arranged.
The utility model has the advantages that:
this structure can realize pegging graft fast, through accurate concentric counterpoint, reaches sealedly, and the installation operation during convenient construction is convenient to be dismantled simultaneously.

Wherein 1 is a butt joint body A; 2 is a butt joint body B; 3 is a plug-in rod end; 4 is a baffle body; 5 is a steel ball; 6 is a spring; 7 is a sealing ring A; 8 is a sealing ring B; and 9 is a thread.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a quick butt joint structure for a sucker rod comprises a butt joint body a (1) and a butt joint body B (2), and is characterized in that the butt joint body a (1) and the butt joint body B (2) are connected through a thread (9), and the middle of the butt joint body a and the butt joint body B is sealed by a sealing ring B (8); the butt joint body A (1) and the butt joint body B (2) are respectively provided with an inserting rod end (3), and a through hole on the inserting rod end is provided with a sealing ring A (7); symmetrical blocking bodies (4) are fixedly connected to two sides of a through hole in the butt joint body A (1) and the butt joint body B (2), a steel ball (5) is placed in a space between the blocking bodies (4), and the steel ball (5) is supported by a spring (6).
The two sides of the through hole in the butt joint body A (1) and the through hole in the butt joint body B (2) are connected with symmetrical blocking bodies (4) through welding.
The pushing structure is composed of the blocking body (4), the steel ball (5) and the spring (6), 4 groups can be fixedly connected in the butt joint body A (1) and the butt joint body B (2) and are arranged according to four symmetrical positions, and two groups are also symmetrically arranged.
The utility model discloses a theory of operation is:
the butt joint body A and the butt joint body B are inserted into the two butted oil rods respectively, then butt joint is carried out, thread fixing is carried out, the oil rods are butted tightly to be in contact, sealing is carried out through the sealing rings, the thread fixing is carried out, the oil rods cannot move, the two rods are butted under the action of the steel ball and the spring in the process of extrusion propulsion, and the blocking body prevents the ball from being pushed out. The moving range of the ball does not exceed the offset of the oil rod.
