Abstract
The utility model discloses a kind of screw column, comprise screw column, described screw column is cylindrical, and column body offers the penetration hole of subtriangular structure, and arc is arranged on penetration hole three limits; Screw column outer side surface arranges three outward extending rib structures.The invention also discloses another kind of screw column, comprise screw column, described screw column is cylindrical, and column body offers the penetration hole of polygon structure, and penetration hole at least has four arc-shaped sides; Screw column outer side surface arranges a plurality of outward extending rib structures.
Description
Technical field
The utility model relates to mechanical field, more specifically to a kind of screw column.
Background technique
At mechanical field, screw is connected the very large effect of playing with device at some equipment, but screw often produces effect of stress to the device being connected in joint, nut also produces corresponding stress to being connected apparatus surface, thereby the normal packing ring mode that adopts increases effect of stress area to reduce pressure at present, but screw rod also produces stress to being connected interior of articles, easily cause being connected the surface of device for a long time and be connected the inner slight crack that produces in place.
Summary of the invention
The purpose of this utility model is to overcome prior art deficiency.For achieving the above object, the utility model has adopted following technological scheme:
A screw column, comprises screw column, and described screw column is cylindrical, and column body offers the penetration hole of subtriangular structure, and arc is arranged on penetration hole three limits; Screw column outer side surface arranges three outward extending rib structures.
Three described rib structures are corresponding with three arc-shaped side mid points of penetration hole respectively.
A screw column, comprises screw column, and described screw column is cylindrical, and column body offers the penetration hole of polygon structure, and penetration hole at least has four arc-shaped sides; Screw column outer side surface arranges a plurality of outward extending rib structures.
Described penetration hole cross section profile is quadrilateral.
Described rib structure quantity equates with penetration hole limit quantity.
Described rib structure is corresponding with four arc mid point limits of penetration hole respectively.
The utlity model has following advantage: screw column can effectively slow down and is connected apparatus surface and inside cracks, and apparatus structure is simple, is easy to produce.
Accompanying drawing explanation
Fig. 1 is triangle penetration hole structure screw column structural representation;
Fig. 2 is triangle penetration hole structure screw column plan view;
Fig. 3 is quadrilateral penetration hole structure screw column structural representation.
Wherein, 1, rib structure; 2, penetration hole; 3, screw column; 4, the body that is fixed; 5, rib structure; 6, screw column; 7, penetration hole; 8, the body that is fixed.
Embodiment
