Abstract
The utility model provides a part of oil extracting devices in the field of machinery, in particular to a coupling preset type upset forging anti-dropping solid sucker rod, wherein a rod fixing head is arranged on the rod body of the sucker rod, the rod fixing head is inserted into a coupling hole of a coupling, the coupling is screwed with connecting rod external threads of a connecting rod through inner threads of the coupling and plugs the rod fixing head, the rod body and the connecting rod can be extended according to needs and then are connected with another coupling, which forms the sucker rod with sufficient length. Since the sucker rod is the anti-dropping solid sucker rod, which has high strength and good repeated use property, and is easy to repair, the rod fixing head in the coupling can be primarily formed through upset forging, which reduces the consumption of processing steps, materials and working time, and prevents the sucker rod from dropping from the coupling. The sucker rod has the characteristics of high strength, long service life and low cost, and is suitable for processing. The sucker rod is suitable for oil extracting operation of oil wells in oil fields.
Description
Technical field
The utility model provides the oil production equipment parts of mechanical field, specifically collar preset formula upsetting anti-loosing solid pumping rod.
Background technology
Before the utility model proposes, the sucker rod that is used for oil well oil-pumping is a direct-coupled type mechanism, directly connect to tend to cause and disconnectedly take off phenomenon and be used for box cupling that sucker rod connects, when being particularly useful for screw bolt well, cause the excessive well head maintenance process shackle difficulty that causes of torsion easily.
Summary of the invention
In order to overcome the shortcoming of existing sucker rod, the utility model provides a kind of collar preset formula upsetting anti-loosing solid pumping rod.This sucker rod connects by box cupling and the transfer torque solution prevents the technical problem that sucker rod comes off.
The scheme that the utility model technical solution problem is adopted is: the sucker rod body of rod is provided with the solid head of bar, and the solid head of bar interts and is installed in the box cupling hole of box cupling, and the connecting rod external screw thread of box cupling by box cupling internal thread and connecting rod spins and block bar head admittedly.The body of rod can prolong as required with connecting rod and be connected with another box cupling, constitutes sufficiently long sucker rod.
Good effect is: since the utility model be anti-loosing solid pumping rod, intensity height, be beneficial to reparation, reusability is good, and the solid head of the bar in box cupling can be by the upsetting one-shot forming, reduce the processing link and the consumption in material and man-hour, and prevent that sucker rod from coming off from box cupling.Have the intensity height, the life-span is long, cost is low, be suitable for machining characteristics.Suit in the oil field, to use in the oil well oil-pumping operation.
Description of drawings
Fig. 1 is the utility model structure chart
Among the figure, the 1. body of rod, the solid head of 1.1. bar, 2. box cupling, 2.1. box cupling hole, 2.2. box cupling internal thread, 3. connecting rod, 3.1. connecting rod external screw thread.
The specific embodiment
According to shown in Figure 1, the sucker rod body of rod 1 is provided with solid 1.1 on bar, and the solid head of bar interts and is installed in the box cupling hole 2.1 of box cupling 2, and the connecting rod external screw thread 3.1 of box cupling by box cupling internal thread 2.2 and connecting rod 3 spins and block the solid head of bar.The body of rod can prolong as required with connecting rod and be connected with another box cupling, constitutes sufficiently long sucker rod.
The body of rod of sucker rod of the present utility model, connecting rod and box cupling all can adopt the upsetting processing technology to make, so compact structure, abrasion resistance are good, and one-shot forming, save material and machining period.
The solid head of the box cupling of making by upsetting and the solid body of rod and bar can prevent that sucker rod from coming off from box cupling, the generation of minimizing accident.
Also, continue to reuse because sucker rod is a solid hopkinson bar, and axial strength is big, and is counter-bending, makes it straight even also can repair after the bending.
Therefore, the utility model sucker rod long service life, material-saving, good energy saving property, and prevent that sucker rod from coming off.
Claims (1)
1, collar preset formula upsetting anti-loosing solid pumping rod, it is characterized in that: the sucker rod body of rod (1) is provided with the solid head of bar (1.1), the solid head of bar interts and is installed in the box cupling hole (2.1) of box cupling (2), and the connecting rod external screw thread (3.1) of box cupling by box cupling internal thread (2.2) and connecting rod (3) spins and block bar head admittedly.
