Abstract
The utility model provides a localizer for pumping rod centralizer, relating to an improved localizer structure for pumping rod centralizer used on pumping well. The utility model comprises an outer sleeve (1) and a plastic inner sleeve (2), with the outer sleeve (1) connected with the plastic inner sleeve (2) by way of threaded connection. A dovetail furrow (5) is arranged axially at the threaded hole (4) of the outer sleeve (1), with a dovetail tenon (3) embedded in the dovetail furrow (5). An extension mouth (6) is arranged axially in the lateral wall of the plastic inner sleeve (2), and an open slot (7) is arranged in the external surface of the lateral wall corresponding to the extension mouth (6) in the plastic inner sleeve (2). The utility model can be arranged fixedly on the pumping rod in any locations, and has the advantages of easy assembly and disassembly, fixed fastening with the pumping rod without loosening, sliding and aging. The utility model has also the advantages of light weight, low cost, low consumption of time and labor in manufacturing.
Description
Technical field: the utility model relates to the improvement of oilfield pumping well with the locator structure of oil pumping rod centering device.
Background technology: the existing positioner that is used for oil pumping rod centering device is fixed in sucker rod with following dual mode: the one, and adopt key pin that positioner is fixed on the sucker rod, key pin is in case loosening, centralizer is together with positioner landing downwards together, do not have the effect of setting upright, particularly inclined shaft can cause the very serious oil pipe and the eccentric wear of rod collar; Another kind is with injection machine plastics directly to be injected in the mould on the sucker rod, makes it be fixed on a certain position on the sucker rod, forms the positioner of fixing centralizer.Directly be injected into the positioner on the sucker rod, need prior batch production production, have the cost of production height, transportation is inconvenient, can not dismounting and change, increase shortcomings such as failsafe link to rod-pumped well.
The utility model content: the purpose of this utility model is the locator of a kind of oil pumping rod centering device of development, it have easy for installation, dismounting easily, fixed with sucker rod, loosening, not landing, characteristics in light weight, that cost is low.The utility model is made up of cover 2 in overcoat 1, the plastics, overcoat 1 is threaded with cover 2 in the plastics, overcoat 1 axially has dovetail groove 5 at screwed hole 4 places, stud with dovetail 3 in the dovetail groove 5, cover 2 axially has flexible mouthful 6 in the plastics on a sidewall, is axially arranged with open slot 7 on the outer wall of flexible mouthful 6 another relative sidewall on the cover 2 in the plastics.The utility model can install and fix it on sucker rod as required in any occasion, has easy for installation, dismounting easily, fixed with sucker rod, loosening, not landing, not aging, in light weight, cost is low, processing and fabricating is time saving and energy saving advantage.
Description of drawings: Fig. 1 is overall structure master's sectional view of the present utility model, Fig. 2 is the structural representation of the dovetail groove 5 on the overcoat 1, Fig. 3 is the structural representation of dovetail 3, Fig. 4 is the front view of cover 2 in the plastics, Fig. 5 is the vertical view of cover 2 in the plastics, and Fig. 6 is the structural representation of the specific embodiment two, and Fig. 7 is the structural representation of the specific embodiment three, Fig. 8 is the structural representation of the specific embodiment four, and Fig. 9 is the structural representation of the specific embodiment five.
The specific embodiment one: present embodiment is made up of cover 2 in cast steel overcoat 1, the plastics, cast steel overcoat 1 is threaded with cover 2 in the plastics, cast steel overcoat 1 axially has dovetail groove 5 at screwed hole 4 places, stud with dovetail 3 in the dovetail groove 5, cover 2 axially has flexible mouthful 6 in the plastics on a sidewall, is axially arranged with open slot 7 on the outer wall of flexible mouthful 6 another relative sidewall on the cover 2 in the plastics.The upper end internal orifice of overcoat 1 is a bell 8, and the upper end outer wall of cover 2 is cone tables 9 in the plastics.
The specific embodiment two: the outer wall of the overcoat 1 in the present embodiment is a circle 10, and other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: the difference of the present embodiment and the specific embodiment one is, the outer wall of overcoat 1 is square 11, and other composition is identical with the specific embodiment one with annexation.
The specific embodiment four: the difference of the present embodiment and the specific embodiment one is that the outer wall of overcoat 1 is a hexagon 12, and other composition is identical with the specific embodiment one with annexation.
The specific embodiment five: the difference of the present embodiment and the specific embodiment one is that the outer wall of overcoat 1 is an octagon 13, and other composition is identical with the specific embodiment one with annexation.
Operating principle: the utility model is before fixing on sucker rod, earlier the dovetail on the overcoat 13 is taken down from overcoat 1, then cover 2 in the plastics is broken into two with one's hands along flexible mouthful 6, because cover 2 is provided with open slot 7 in the plastics, so cover 2 is easy to be broken into two with one's hands in the plastics, cover 2 in the plastics of breaking into two with one's hands is enclosed within on the sucker rod, elasticity by plastics self, cover 2 is embraced sucker rod in the plastics, the overcoat 1 that will take off dovetail 3 this moment is enclosed within on the sucker rod, again dovetail 3 is inserted in the dovetail groove 5 of overcoat 1, along screw thread cover in overcoat 1 and the plastics 2 is tightened together, the cone table 9 in the plastics on the cover 2 enters in the bell 8 on the overcoat 1, and is stubborn more tight more, the screw thread that is subjected to overlap on 2 in the plastics restricts, and dovetail 3 can be from landings in the dovetail groove on the overcoat 15.
