Abstract
The utility model provides an abrasionproof uncoupling hoop, it is used for two connections between the sucker rod, and it includes the coupling body, the inside passageway that is used for installing oil pipe that is equipped with of coupling body, the length of passageway are greater than oil pipe's length, the center of coupling body surface is that the cross -section is trapezoidal coupling recess, is equipped with two anti -abrasion strip on the coupling body of coupling recess both sides, and two cross -sections that the both ends of coupling body were equipped with the symmetry respectively are trapezoidal anti -abrasion strip mounting groove, every anti -abrasion strip respectively and cooperate rather than two anti -abrasion strip mounting grooves that correspond one side, anti -abrasion strip is equipped with with above -mentioned anti -abrasion strip mounting groove matched with cross -section protrudingly for trapezoidal screens. The utility model discloses the sound construction, the security is high, and long service life has reduced the fault rate.
Description
Technical field
This utility model relates to oil exploitation technical field of tools, particularly to a kind of abrasionproof uncoupling hoop。
Background technology
Oil exploitation is generally adopted bar pump oil pumping mode, and sucker rod can produce friction with oil pipe in the process of pumping, and causes that sucker rod rubs, and oil pipe is worn out。Existing oil pumping rod centering device mainly solves righting problem, and its structure is insecure, quick abrasion, and service life is short, adds the fault rate of sucker rod, and security performance is relatively low, it would be highly desirable to improve further。
Summary of the invention
In order to overcome the defect of prior art, this utility model provides techniques below scheme:
A kind of abrasionproof uncoupling hoop, it is for the connection between two sucker rods, it includes box cupling body, described box cupling body interior is provided with the passage for installing oil pipe, the length of passage is more than the length of oil pipe, the center of described box cupling body outer surface is cross section is trapezoidal box cupling groove, the box cupling body of box cupling groove both sides is provided with two chafing strips, two cross sections being respectively arranged at two ends with symmetry of box cupling body are trapezoidal chafing strip mounting groove, each chafing strip matches with two chafing strip mounting grooves of corresponding side respectively, it is protruding that described chafing strip is provided with the screens that the cross section matched with above-mentioned chafing strip mounting groove is trapezoidal。
Further, in the same plane, and the inclination angle of two sides is 45 ° in the side of the side of the inner opposite end of said two chafing strip and box cupling groove。
Further, described box cupling body is non-metallic material。
Further, described chafing strip adopts Wear-resistant, high-temperature resistant oil resistant material to make。
The had the benefit that sound construction of this utility model, safety is high, and long service life reduces fault rate。
Accompanying drawing explanation
Fig. 1 is this utility model structural representation。
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining。
As shown in Figure 1, a kind of abrasionproof uncoupling hoop, it is for the connection between two sucker rods, it includes box cupling body 2, described box cupling body 2 is internal is provided with the passage for installing oil pipe 1, the length of passage is more than the length of oil pipe 1, the center of described box cupling body 2 outer surface is cross section is trapezoidal box cupling groove 21, the box cupling body of box cupling groove 21 both sides is provided with two chafing strips 3, two cross sections being respectively arranged at two ends with symmetry of box cupling body 2 are trapezoidal chafing strip mounting groove, each chafing strip 3 matches with two chafing strip mounting grooves of corresponding side respectively, it is trapezoidal screens projection 31 that described chafing strip 3 is provided with the cross section matched with above-mentioned chafing strip mounting groove。
In the same plane, and the inclination angle of two sides is 45 ° in the side of the side of the inner opposite end of said two chafing strip 3 and box cupling groove。Described box cupling body 2 is non-metallic material。Described chafing strip adopts Wear-resistant, high-temperature resistant oil resistant material to make。
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by this utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model。Therefore, protection domain of the present utility model should be as the criterion with claims protection defined。
