Abstract
The utility model discloses a kind of nut and the special tool for turning this nut, nut comprises the first cylindrical body, and the first its center is provided with tapped through hole, and the first cylindrical body two ends offer the cross recess rotated for turning it respectively; This special tool comprises the second cylindrical body, and the second cylindrical member at one end has hexagon, and the second its center is provided with and runs through hexagon and the second cylindrical guide through hole, and the second cylindrical body the other end has four circumferentially uniform projections matched with cross recess.
Description
Technical field
The utility model relates to a kind of nut and the special tool for turning this nut.
Background technique
Nut usually uses with bolt, screw fit, plays connection fastening machines part.Common hexagon nut is because of the cause of hexagon head, and radial dimension is comparatively large, and when some part installing space is less, its use is restricted.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides the little nut of a kind of radial dimension and the special tool for turning this nut.
The utility model solves the technological scheme that its technical problem adopts: a kind of nut, comprises the first cylindrical body, and the first its center is provided with tapped through hole, and the first cylindrical body two ends offer the cross recess rotated for turning it respectively.
When this nut is connected fastening machines part with screw flight, special tool need be adopted to turn this nut, this special tool comprises the second cylindrical body, second cylindrical member at one end has hexagon, second its center is provided with and runs through hexagon and the second cylindrical guide through hole, and the second cylindrical body the other end has four circumferentially uniform projections matched with cross recess.
The beneficial effects of the utility model are: nut radial dimension of the present utility model is little, and its two ends all offer cross recess, is connected more convenient with bolt, and the special tool structure turning this nut is simple, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model nut;
Fig. 2 is the structural representation of the utility model special tool.
In figure: 1. the first cylindrical body; 2. tapped through hole; 3. cross recess; 4. the second cylindrical body; 5. hexagon; 6. guide through hole; 7. projection.
Embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of nut as shown in Figure 1, comprises the first cylindrical body 1, first cylindrical body 1 center and is provided with tapped through hole 2, and the first cylindrical body 1 two ends offer the cross recess 3 rotated for turning it respectively.
A kind of special tool turning this nut as shown in Figure 2, comprise the second cylindrical body 4, second cylindrical body 4 one end has hexagon 5, second cylindrical body 4 center is provided with the guide through hole 6 running through hexagon 5 and the second cylindrical body 4, second cylindrical body 4 the other end has four circumferentially uniform projections 7 matched with cross recess 3, the diameter of the second cylindrical body 4 is less than or equal to the diameter of the first cylindrical body 1, be convenient to this special tool stretch in hole in piece part and turn this nut, the diameter of guide through hole 6 is greater than the external diameter of the bolt be connected with this nut thread.
During use, this special tool is sleeved on by guide through hole 6 on the bolt be connected with this nut thread, then four of special tool projections 7 are snapped in the cross recess 3 of this nut respectively, pulled the hexagon 5 of this special tool by spanner, get final product fastening or unscrew this nut.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
