Abstract
The utility model discloses a protection sleeve which is formed by the combined connection of an upper connecting sleeve, a corrugated tube, a spring, a lower connecting sleeve and a connecting sleeve and has the advantages of convenient mounting and good sealing. The sealing protection sleeve for the oil extraction rod of the oil extractor is realized by the following technical scheme: in the protection sleeve, the upper connecting sleeve, the corrugated pipe, the spring and the lower connecting sleeve are sequentially connected; the upper connecting sleeve is connected with the upper end of the oil extraction rod, and the lower connecting sleeve is connected with the lower end of the oil extraction rod; the spring is connected with an internal thread of the upper connecting sleeve and connected with an internal thread of the corrugated tube, and the corrugated tube is connected with an internal thread of the upper connecting sleeve; and the lower connecting sleeve is connected with an internal thread of the spring.
Description
Technical field
The utility model relates to a kind of protection tube that is connected and forms by bellows, spring, upper joint sleeve, lower joint sleeve, adapter sleeve, relate in particular to the sleeve pipe that is used for oil pumping machine oil pumping bar usefulness seal protection.
Background technology
At present, still untappedly in this field go out oil pumping machine oil pumping bar seal protection sleeve pipe.
This protection tube must possess multifrequency nature and satisfy application conditions.
At first, protection tube must have powerful anti-mechanical property, because they are used to field easy to wear.
Secondly, protection tube must have good sealing property, because their effect is that sucker rod is carried out seal protection.
Once more, protection tube must be easy to install.
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of oil pumping machine oil pumping bar Sealed casing pipe is provided.It is connected by bellows, spring, adapter sleeve and forms.Described bellows adopts with upper joint sleeve and is threaded.
Described spring all adopts with upper joint sleeve with bellows, spring and is threaded.
Described lower joint sleeve adopts with screw thread and is threaded.
The utility model content
The utility model has solved these shortcomings with a kind of protection tube that is combined by upper joint sleeve (1), bellows (2), spring (3), lower joint sleeve (4), adapter sleeve (5), and a kind of easy for installation, good airproof performance, nonabradable protective casing are provided.
In order to solve the technical problem of above-mentioned existence; the utility model adopts following technology law scheme: in protection tube; upper joint sleeve (1), bellows (2), spring (3), lower joint sleeve (4), adapter sleeve (5) are linked in sequence; described upper joint sleeve (1) is connected with the sucker rod upper end, and lower joint sleeve (4) is connected with the sucker rod lower end.
Described upper joint sleeve (1) is a sphere with the joint face of sucker rod.
The spring wire cross section of described spring (3) can be rectangle, circle, trapezoidal.
The material of described bellows (2) can be metal, rubber, fiber, nylon, polyvinyl.
Described spring (3) is threaded with upper joint sleeve (1), and spring (3) is threaded with bellows, and bellows (2) is connected with the upper joint sleeve screw thread, and lower joint sleeve (4) is connected with spring thread.
Because adopt technique scheme, the protection tube that the utility model provides has such beneficial effect, promptly easy for installation, good airproof performance, simple in structure.
