Abstract
The utility model relates to an anti-theft device, in particular to an anti-theft device for an oil-field well. The anti-theft device for the oil-field well comprises a bolt, a screwed plug, a rotating sleeve, and a bearing, wherein the head of the bolt is in flat and vertical structure, the bolt passes through the bearing to be matched with the screwed plug, and the rotating sleeve connected with the bearing is arranged outside the bolt and is in close fit with the screwed plug though the bearing. The anti-theft device for the oil-field well has the advantages of enhancing anti-theft and anti-damage capabilities of wellhead devices or equipment, being incapable of being opened by normal tools, convenient to use, capable of being installed and dismantled by a special wrench so that maintenance is facilitated and universality is strong, and applied to oil field operation anti-theft devices, reducing the number of phenomena that equipment is damaged and crude oil is stolen, improving production efficiency, and reducing labor intensity of workers.
Description
Technical field
The utility model relates to a kind of anti-theft device, and particularly a kind of oil field well is used anti-theft device.
Background technology
Oil pumper and used bolt and the instrument of production tree well head key position all are current versions at present; Even anti-theft measure is adopted at the position that has; Because of instrument is easy to copy, anti-theft effect is unsatisfactory, and often generation equipment is destroyed and the stolen phenomenon of crude oil; Cause to production to have a strong impact on, cause very big burden for staff's operation.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of oil field well to use anti-theft device, is convenient to safeguard, highly versatile has reduced equipment and has been destroyed the phenomenon stolen with crude oil.
Its technical scheme is: comprise bolt, plug, rotary sleeve, bearing; The head of bolt is flat vertical stratification; Bolt passes bearing and matches with plug, and the outside of bolt is provided with the rotary sleeve that is connected with bearing, and described rotary sleeve closely cooperates through bearing and plug.
The beneficial effect of the utility model is: strengthen the antitheft and the anti-damage ability of wellhead assembly equipment, conventional instrument can't be opened, and is easy to use; Utilize the special spanner just can installation and removal, be convenient to safeguard highly versatile; Suitable oil field operation anti-theft device; Reduced equipment and be destroyed the phenomenon stolen, improved production efficiency, alleviated staff's labour intensity with crude oil.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: bolt 1, plug 2, rotary sleeve 3, bearing 4.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises bolt 1, plug 2, rotary sleeve 3, bearing 4; The head of bolt 1 is flat vertical stratification; Bolt 1 passes bearing 4 and matches with plug 2, and the outside of bolt 1 is provided with the rotary sleeve 3 that is connected with bearing 4, and described rotary sleeve 3 closely cooperates through bearing 4 and plug 2.
This product is to frequent being destroyed and the stolen problem of occurring of the import of pumping unit of well and production tree; Change the hexagonal structure of conventional bolt; Adopt flat vertical stratification; Through cooperating with special tool, the bolt outside adds movable rotation protective jacket or fixed protection cover, makes conventional instrument and pipe wrench all can't open.Strengthen the antitheft and the anti-damage ability of wellhead assembly equipment, conventional instrument can't be opened, and is easy to use; Utilize the special spanner just can installation and removal, be convenient to safeguard highly versatile; Reduced equipment and be destroyed the phenomenon stolen with crude oil; Improved production efficiency, alleviated staff's labour intensity, the product antitheft beyond the import of oil pumper, production tree also is suitable for.
