A special type of sucker rod with a uniquely shaped connector and full coverage.

Abstract

This utility model discloses a special sucker rod with a non-circular connector positioning and full coverage. The fixing mechanism also includes a locking component and a fixing component. The locking component includes a first hexagonal pipe fixedly connected to one end of the male connector, a first fixing ring on the outer wall of the male connector, and multiple first grooves evenly spaced on the outer wall of the first fixing ring. A circular groove is formed on one side of the outer wall of the male connector, and multiple sliders are slidably connected at equal distances on the inner wall of the circular groove. A retaining ring is fixedly connected to one side of the slider. In this utility model, when the fixing block reaches the designated position, the retaining ring is rotated, and the locking block on one side of the retaining ring will be aligned with the strip groove on the top of the fixing block, which can fix the fixing component. This means that during the docking of the male and female connectors, it is not necessary to use bolts for fixing, but can be fixed by mechanical linkage. The second hexagonal pipe on the side of the female connector will fully cover the first hexagonal pipe on the male connector to prevent leakage during use.

Description

Technical Field

[0001] This utility model relates to the field of sucker rod technology, specifically a special sucker rod with a non-circular joint positioning and full coverage. Background Technology

[0002] Traditional sucker rods are typically made of carbon steel or alloy steel, with a circular threaded connection at the joint. The surface of the rod is protected by coating with a metal plating (such as nickel or chromium) or spraying with an anti-corrosion coating (such as epoxy resin).

[0003] In the jointing of irregularly shaped sucker rods, traditional methods have always relied on hexagonal or square connectors. During the jointing process, the interface angles and positions must be repeatedly calibrated to ensure a proper fit. After the initial jointing is completed, multiple sets of bolts must be symmetrically installed for secondary tightening. This operational mode not only consumes a significant amount of time in securing the two sucker rods, but the frequent bolt loading and unloading also easily causes thread wear, thus increasing subsequent maintenance costs. This lengthy jointing process severely restricts the turnover efficiency of sucker rods in oilfield operations. Utility Model Content

[0004] The purpose of this invention is to provide a special sucker rod with a non-circular joint positioning and full coverage, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a special sucker rod with a non-circular joint positioning and full coverage, including a rod body, a male end on one side of the rod body, and fixing mechanisms on both sides of the rod body;

[0006] The fixing mechanism further includes a locking component and a fixing component. The locking component includes a first hexagonal pipe fixedly connected to one end of the male connector, a first fixing ring on the outer wall of the male connector, a plurality of first grooves evenly spaced on the outer wall of the first fixing ring, a circular groove on one side of the outer wall of the male connector, a plurality of sliders slidably connected at equal distances on the inner wall of the circular groove, a retaining ring fixedly connected to one side of the slider, and a plurality of retaining blocks fixedly connected at equal distances on one side of the retaining ring.

[0007] In one example, an arc-shaped plate is fixedly connected to one side of each of the first grooves.

[0008] In one example, the fixing component includes a female head disposed on one side of the male head, a second hexagonal pipe fixedly connected to one side of the female head, and the second hexagonal pipe being slidably connected to a first hexagonal pipe. A second fixing ring is fixedly connected to the outer wall of the female head, and a second groove is formed on one side of the second fixing ring.

[0009] In one example, each of the inner walls of the second groove has a circular hole on both sides, and a first connecting rod is rotatably connected between each pair of opposite circular holes.

[0010] In one example, a fixing block is fixedly connected to the other end of each of the first connecting rods, and an arc-shaped groove is opened at the bottom of each fixing block, with the arc-shaped groove facing the arc plate.

[0011] In one example, each of the fixing blocks has a slot on its top, and the slot is directly opposite the position of the locking block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The male connector is located on one side of the rod body. A first hexagonal tube is provided on one side of the male connector. A first fixing ring is located on the outside of the male connector, and a first groove is located outside the first fixing ring. A circular groove is located on one side of the outer wall of the male connector, and a slider slides inside the circular groove. The slider connects with an external retaining ring, allowing the retaining ring to rotate outside the male connector. A retaining block is located on one side of the retaining ring. During use, the fixing component on one side slides into the first groove. When the retaining block enters the first groove and reaches the designated position, the retaining ring can be rotated. The retaining block on one side of the retaining ring then aligns with the strip groove on the top of the retaining block, thereby fixing the fixing component. This eliminates the need for bolts during the connection of the male and female connectors; fixation is achieved solely through mechanical linkage. Furthermore, the second hexagonal tube on the female connector completely covers the first hexagonal tube on the male connector, preventing leakage during use.

[0014] A second fixing ring is provided on one side of the female connector. The outer wall of the second fixing ring has a second groove, and the inner wall of the second groove has a round hole. A first connecting rod is rotatably connected to the inner wall of the round hole. A fixing block is provided on one side of the first connecting rod, and the bottom of the fixing block has an arc groove. When the female connector and the male connector are connected, the first connecting rod is pushed forward and enters the interior of the first groove. The arc plate located inside the first groove will lift the fixing block and then lower it until the arc groove and the arc plate fit perfectly. Then the male connector and the female connector can be connected, making it more convenient to use the rod. Attached Figure Description
