Description
Technical field
This utility model relates to petroleum machinery equipment technical field, relates in particular to a kind of sucker rod screw thread protection set。
Background technology
Sucker rod screw thread protection set Main Function has two aspects, and first protection sucker rod screw thread stops corrosion resistant coating to enter screw thread position in preservation process；Its two be protection screw thread, it is prevented that collide with screw thread and shoulder in transportation。The screw thread protection of prior art is enclosed within and prevents corrosion resistant coating from polluting and avoiding colliding with all out of question, but the screw thread of prior art protection set and threaded engagement excessively closely, unloading time resistance excessive, not easily unload；And the periphery of protection set is without impetus, it is impossible to firmly, be not easy when going bail for sheath to unload protection set。
Summary of the invention
The purpose of this utility model is in that the defect for above-mentioned prior art, it is provided that a kind of sucker rod screw thread protection set, can easily unload screw thread protection set, save the muscle power of operator, reduce labor intensity, improve work efficiency。
To achieve these goals, the technical solution of the utility model is:
A kind of sucker rod screw thread protection set, including the sleeve body of hollow and the guide sleeve body of the structure that links into an integrated entity；One end of described sleeve body is provided with capping, and the outer circumference diameter of described guide sleeve body is more than the outer circumference diameter of sleeve body, and the inner circumferential diameter of described guide sleeve body is more than the inner circumferential diameter of sleeve body；The peripheral cross-section of described sleeve body is regular hexagon, the inner circumferential cross section of described sleeve body is circular, the direction, the inner circumferential center of circle of described sleeve body is raised with several isolation bars, the length direction of described isolation bar is arranged along the length direction of sleeve body, and described isolation bar is uniformly distributed in the inner circumferential of sleeve body；The periphery of described guide sleeve body, inner circumferential cross section are circular, and the inner circumferential of described guide sleeve body is provided with several shading rings。The inner circumferential of sleeve body is raised with isolation bar; the inner circumferential of guide sleeve body arranges shading ring; the contact area of inner circumferential and the sucker rod of the inner circumferential of sleeve body, guide sleeve body can be reduced; reduce frictional force; spanner or specific purpose tool are inserted on six side peripheries of sleeve body; rotating spanner or specific purpose tool, utilize general spanner can ease rotation fastening sucker rod screw thread protection set, then artificial hands is unloaded。Save the muscle power of operator, reduce labor intensity, improve work efficiency。
As the improvement to technique scheme, the periphery of described guide sleeve body is provided with the anti-slip veins increasing frictional force。So, when unloading sucker rod screw thread protection set manually, it is possible to prevent from skidding。
As the improvement to technique scheme, the periphery of described sleeve body and guide sleeve body is provided with reinforcement in junction。So, it is possible to increase the bonding strength of sleeve body and guide sleeve body, the intensity of whole sucker rod screw thread protection set is increased。
Compared with prior art, this utility model has the advantage that and has the benefit effect that
Sucker rod screw thread of the present utility model protection set, is enclosed within sucker rod, during unloading; spanner or specific purpose tool are inserted on six side peripheries of sleeve body; rotating spanner or specific purpose tool, after being rotated by sucker rod screw thread protection set, can easily unload screw thread protection set with hands。Time saving and energy saving。Can easily unload screw thread protection set, save the muscle power of operator, reduce labor intensity, improve work efficiency。

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, any amendment made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
As illustrated in fig. 1 and 2, sucker rod screw thread of the present utility model protection set, including the sleeve body 1 of hollow and the guide sleeve body 2 of the structure that links into an integrated entity；One end of described sleeve body 1 is provided with capping 3, and the outer circumference diameter of described guide sleeve body 2 is more than the outer circumference diameter of sleeve body 1, and the inner circumferential diameter of described guide sleeve body 2 is more than the inner circumferential diameter of sleeve body 1；The peripheral cross-section of described sleeve body 1 is regular hexagon, the inner circumferential cross section of described sleeve body 1 is circular, the direction, the inner circumferential center of circle of described sleeve body 1 is raised with several isolation bars 4, the length direction of described isolation bar 4 is arranged along the length direction of sleeve body 1, and described isolation bar 4 is uniformly distributed in the inner circumferential of sleeve body 1；The periphery of described guide sleeve body 2, inner circumferential cross section are circular, and the inner circumferential of described guide sleeve body 2 is provided with several shading rings 5。The inner circumferential of sleeve body 1 is raised with isolation bar 4, when deforming after isolation bar 4 with thread contact, is squeezed on screw thread, it is prevented that come off from screw thread；The inner circumferential of guide sleeve body 2 arranges shading ring 5, contacts with sucker rod shoulder, it is prevented that foreign matter enters, and effectively protects threaded portion。Spanner or specific purpose tool are inserted on six side peripheries of sleeve body 1, rotating spanner or specific purpose tool, utilize general spanner can the sucker rod screw thread protection set of ease rotation fastening, then artificial hands is unloaded。Reduce labor intensity, improve work efficiency。
The periphery of described guide sleeve body 2 is provided with the anti-slip veins 6 increasing frictional force。So, when unloading sucker rod screw thread protection set manually, it is possible to prevent from skidding。
The periphery of described sleeve body 1 and guide sleeve body 2 is provided with reinforcement 7 in junction。So, sleeve body 1 and the bonding strength of guide sleeve body 2 can be increased, increase the intensity of whole sucker rod screw thread protection set。
