Abstract
The utility model relates to a clamp nut matched with a fastening bolt. The clamp nut comprises a body, wherein the body is tubular, and the inner surface of the body is provided with a screw thread. The clamp nut is characterized in that axial convex ribs are uniformly distributed on the outer surface of the body so that a clamping slot is formed between every two adjacent convex ribs. If the outer surface of the clamp nut is worn or deforms after the clamp nut is used many times, a fastening tool matched with the clamping slot can also be used for fastening or dismounting, and thus, the service life of the nut is prolonged.
Description
Technical field
The utility model relates to a kind of secure component, is a kind of tightening nut that matches with clamping bolt specifically, is applicable to the connection between the mechanical part.
Background technique
At present, the supporting screw bolt and nut of fastening most use between the mechanical part, nut wherein is hexagon nut.This nut is in dismounting and fastening process repeatedly, and the outer-hexagonal limit can produce serious wearing and tearing and distortion, makes between nut and the fastened tools and produces slippage, can't continue to use, and therefore the working life of this nut is shorter.
The model utility content
The problem that the utility model will solve provides a kind of tightening nut, and the working life of this tightening nut is longer.
For addressing the above problem, adopt following scheme:
The tightening nut of the utility model comprises the body of tubulose, and its internal surface is processed with screw thread, is characterized in that the outer surface of said body is evenly equipped with axial convex tendon, so that between adjacent two convex tendons, form draw-in groove.
The further improvement project of the utility model is that said convex tendon is 6, and the part of the transverse section of convex tendon except that the draw-in groove cell wall is the ridge shape, and the ridge face of adjacent two convex tendons at grade.
Adopt such scheme, have the following advantages:
Because the tightening nut outer surface of the utility model has draw-in groove; Can use and carry out fastening with the supporting fastened tools of draw-in groove or dismounting; Stressed surface of contact is little, and the tolerance intensity of convex tendon is high, therefore is difficult for producing wearing and tearing and distortion; Can slippage between nut and the fastened tools yet, thus increased the working life of this nut.In addition, the tightening nut of the utility model is compared with onesize hexagon nut, can also save about 20% material.
Description of drawings
Fig. 1 is the radial section figure of hexagon nut in the existing technology;
Fig. 2 is the radial section figure of the tightening nut of the utility model.
Embodiment
As shown in Figure 2, the tightening nut of the utility model comprises body, and this body is a tubulose, and its internal surface has screw thread, and outer surface is evenly equipped with axial convex tendon 1, so that between adjacent two convex tendons, form draw-in groove 2.
Wherein, said convex tendon 1 is 6, and the part of the transverse section of convex tendon 1 except that draw-in groove 2 cell walls is the ridge shape, the ridge face of adjacent two convex tendons at grade, thereby also can use general utility tool to carry out fastening to this nut or the dismounting.
Claims (2)
1. a tightening nut comprises body, and this body is a tubulose, and its internal surface has screw thread, it is characterized in that the outer surface of said body is evenly equipped with axial convex tendon (1), so that between adjacent two convex tendons, form draw-in groove (2).
2. tightening nut as claimed in claim 1 is characterized in that said convex tendon (1) is 6, and the transverse section of convex tendon (1) is the ridge shape except that the part of draw-in groove (2) the cell wall, and the ridge face of adjacent two convex tendons at grade.
