Abstract
The utility model provides an anti-theft screwed plug of an oil discharging hole of a speed changing box of an oil pumping machine, comprising the speed changing box and a screwed plug, wherein the speed changing box is connected with the oil pumping machine; an outer thread of the screwed plug is connected with an inner thread of the speed changing box; the right end surface of the screwed plug is leveled with the right end surface of the speed changing box; the screwed plug enters the speed changing box; a polygonal groove is formed in the right end surface of the screwed plug; a position for the mounting and the dismounting of screw pipe hitting pincers does not exist at the outer part of the screwed plug; stealers can not use a common tool to dismount the screwed plug and can not steal lubricating oil in the speed changing box; and the economic loss caused by that the stealers steal the lubricating oil in the speed changing box can be avoided, and the anti-theft screwed plug has a simple structure and is convenient to mount.
Description
Technical field
The utility model is the assembly on a kind of oil-field oil pumper, is a kind of pumping unit gear shifting box drain oil screws valve for preventing illagel application.
Background technique
Gearbox internal memory on the pumping unit a large amount of lubricating oils, the lubricating oil that changes in the gearbox needs periodic replacement, so, the pumping unit gear shifting box bottom is provided with drain oil, this drain oil is sealed by plug, it with gearbox in box thread be connected, when needing to change the lubricating oil in the gearbox, just plug can be disassembled with general tool rotation plug, therefore, thief is easy to and will plug be dismantled stolen with general tool, cause a large amount of lubricating oils stolen, make the pumping unit cisco unity malfunction, affect oil well production, cause serious economic loss to the oil field.
Summary of the invention
The purpose of this utility model is a kind of pumping unit gear shifting box drain oil screws valve for preventing illagel application of design, make thief plug not dismantled stolen with general tool, can play easily the effect that prevents stolen, avoid the pumping unit lubricating oil stolen, reduce the oilfield economic loss.
The purpose of this utility model is achieved in that and comprises gearbox, plug, gearbox is connected with pumping unit, the outside thread of plug is connected with the internal thread of gearbox, the right side of plug is concordant with the right side of gearbox, plug all enters in the gearbox, has the polygonal groove in the right side of plug.
The beneficial effects of the utility model are: plug all enters in the gearbox, that the plug outside does not have is upper, unload screw thread beats the position that pipe wrench is used, thief can't be dismantled plug with general tool, can't steal the lubricating oil in the gearbox, can avoid stealing the economic loss that the gearbox lubricating oil causes because of thief, the utility model is simple in structure, and is easy for installation.
Description of drawings
Fig. 1 is the utility model embodiment's erection drawing.
Fig. 2 is the right elevation of part 3 among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises gearbox 1, plug 3, gearbox 1 is connected with pumping unit, the outside thread of plug 3 is connected with the internal thread of gearbox 1, the right side of plug 3 is concordant with the right side of gearbox 1, plug 3 all enters 1 li of gearbox, has polygonal groove 2 in the right side of plug 3.
In the polygonal cylinder insertion groove identical with plug 3 right side polygonal grooves 2, be rotated in the forward the polygonal cylinder, thereby plug 3 is installed on the gearbox 1.Because plug 3 is solid bodys, can stop up the fuel outlet on the gearbox 1, gearbox can normally be produced.When needs disassemble plug 3 from gearbox 1, again the polygonal cylinder is inserted 2 li counterrotatings of plug 3 top polygonal grooves, thereby plug 3 is disassembled from gearbox 1.
