The technical solution of the utility model is: the protective cover of internal-thread petroleum machinery workpiece of the present utility model, including top round platform, side
Wall, back cover, dust plug, pulling part, fin, cabinet, external screw thread, anti-slip part, oil filler point；
The top round platform of rigidity, sidewall, back cover are into a single integrated structure, and described top round platform is arranged on outside the top of sidewall, described back cover
It is arranged on the bottom of sidewall, forms upper opening bottom seal " recessed " character form structure；
Having oil filler point on described back cover, be provided with dust plug in described oil filler point, described dust plug is flexibly connected with oil filler point, described anti-
The top of dirt plug is installed with pulling part；
The outside of described sidewall is provided with at least one fin, and the bearing of trend of described fin is consistent with the bearing of trend of sidewall, described plastics
Shell laminating is arranged on the outside of sidewall, and the inwall of described cabinet is provided with the groove matched with fin, by fin and
The interference fit of groove, cabinet can load and unload, the external diameter of described cabinet less than the external diameter of top round platform, described in mould
The outside of material shell is provided with external screw thread, and the female thread of described external screw thread and petroleum machinery workpiece matches.
Described fin is provided with two, and the both sides being arranged on sidewall of symmetry.
The outer wall of described top round platform is provided with anti-slip part.
The material of described dust plug is rubber.
This utility model has the advantage that with good effect:
1, owing to using technique scheme, the female thread of petroleum machinery workpiece can be effectively protected, protective cover of the present utility model,
Existing dust-proof effect, can facilitate again to the internal oiling of screw, maintain, the existing anti-deformation of certain rigidity, can prevent again
Internal threads causes abrasion.
2, fin is vertically arranged, and when can prevent rotary top round platform, cabinet skids relative to sidewall motion, causes and cannot screw in
Phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1-top round platform, 2-sidewall, 3-back cover, 4-dust plug, 5-pulling part, 6-fin, 7-cabinet, 8-external screw thread, 9-
Anti-slip part, 10-oil filler point.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
As it is shown in figure 1, the protective cover of internal-thread petroleum machinery workpiece of the present utility model, including top round platform 1, sidewall 2, back cover 3,
Dust plug 4, pulling part 5, fin 6, cabinet 7, external screw thread 8, anti-slip part 9, oil filler point 10；
The top round platform 1 of rigidity, sidewall 2, back cover 3 are into a single integrated structure, and top round platform 1 is arranged on outside the top of sidewall 2, back cover
3 bottoms being arranged on sidewall 2, form upper opening bottom seal " recessed " character form structure；
Having oil filler point 10 on back cover 3, be provided with dust plug 4 in oil filler point 10, dust plug 4 is flexibly connected with oil filler point 10, dust-proof
The top of plug 4 is installed with pulling part 5；
The outside of sidewall 2 is provided with two fins 6, and the left and right sides being arranged on sidewall of symmetry, the bearing of trend of fin 6 and side
The bearing of trend of wall 2 is consistent, and cabinet 7 laminating is arranged on the outside of sidewall 2, and the inwall of cabinet 7 is provided with convex
The groove that rib 6 matches, by fin 6 and the interference fit of groove, cabinet 7 can installing/dismounting, cabinet 7
