Abstract

A special trapezoidal side-inserted anti-delinking rod for screw pump well belonging to the petroleum machinery oil extraction equipment field consists of a concave trapezoidal side-inserted anti-delinking joint, a connection screw thread, a wrench, and a rod body. During the descending job, a rod stirring is connected through the connection of the special trapezoidal side-inserted anti-delinking rod for screw pump well and a righting short rod, the concave trapezoidal side-inserted anti-delinking joint has a side-inserted connection with a projecting trapezoidal side-inserted anti-delinking joint connected with the righting short rod, the coupling of a connecting device is connected with the connection screw thread of the utility model, and then the anti-delinking nuts are screwed tightly. The well-connected rod stirring prevents the rod stirring from being disengaged from the screw pump well, due to the adoption of the side-inserted connection between a concave trapezoidal trough of the concave trapezoidal side-inserted anti-delinking joint and a projecting joint of the projecting trapezoidal side-inserted anti-delinking joint and also because of the connection between the coupling and the connection screw thread on the outside, with a way of double-insurance.

Description

A kind of trapezoidal side-plug-in anti-avulsion screw bolt well special pole
Affiliated technical field
A kind of trapezoidal side-plug-in anti-avulsion screw bolt well special pole belongs to petroleum machinery oil production equipment field.
Background technique
The sucker rod that is applied to the drive screw pump sump at present generally adopts common sucker rod and tapered shaft head, fan-shaped bar head sucker rod.Common sucker rod generally is applied to the pumping production well and moves reciprocatingly because of it connects for straight thread, is applied to screw bolt well and recovers the oil, and its anti-twisting property is not enough.Tapered shaft head, fan-shaped bar head sucker rod all can cause with the connection part of this rod collar looseningly in screw bolt well body of rod rotary work, cause the dropout accident, so that influence the normal oil producing operation of screw pump.
Summary of the invention
The purpose of this utility model provides a kind of a kind of trapezoidal side-plug-in anti-avulsion screw bolt well special pole of threading off between the sucker rod of preventing.
The purpose of this utility model is achieved in that a kind of trapezoidal side-plug-in anti-avulsion screw bolt well special pole is made of recessed trapezoidal side-plug-in anti-avulsion joint (1), connecting thread (2), spanner side (3), the body of rod (4).During following well operations, set upright quarter butt and connect into rod string by being connected with trapezoidal side-plug-in anti-avulsion screw bolt well special pole, connection is set upright quarter butt and is loaded onto screwed retaining ring (10), spring washer (9), box cupling (6), locking nut (8), is equipped with female (7), recessed then trapezoidal side-plug-in anti-avulsion joint (1) be connected protruding trapezoidal side-plug-in anti-avulsion joint (5) the side inserting of setting upright quarter butt and close, box cupling in the connection set (6) is connected with connecting thread (2) in the utility model, tightens screwed retaining ring (10) at last.The rod string that connects is formed by connecting owing to the protruding trapezoidal joint side of the protruding trapezoidal side-plug-in anti-avulsion joint (5) of recessed dovetail groove that adopts recessed trapezoidal side-plug-in anti-avulsion joint (1) and connection set is slotting, the outside has box cupling (6) to be connected with connecting thread (2) again, with the form of dual fail-safe, prevented the dropout problem of screw bolt well rod string.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that trapezoidal side-plug-in anti-avulsion screw bolt well special pole connects the structural representation of setting upright quarter butt.
Among the figure: 1, recessed trapezoidal side-plug-in anti-avulsion joint, 2, connecting thread, 3, spanner side, 4, the body of rod, 5, protruding trapezoidal side-plug-in anti-avulsion joint, 6, box cupling, 7, be equipped with female, 8, locking nut, 9, spring washer, 10, screwed retaining ring.
Embodiment
The purpose of this utility model can reach in the following manner:
The utility model is made of recessed trapezoidal side-plug-in anti-avulsion joint (1), connecting thread (2), spanner side (3), the body of rod (4).During following well operations, set upright quarter butt and connect into rod string by being connected with trapezoidal side-plug-in anti-avulsion screw bolt well special pole among Fig. 2.
Have recessed dovetail groove on the recessed trapezoidal side-plug-in anti-avulsion joint (1); Spanner side (3) is two sides or cubic, and the diameter range of the body of rod (4) is 19~45mm.

Claims (3)
