Description

Nut

Technical field

This utility model relates to nut technical field, specially nut.

Background technology

Traditional slotted nut annular on nut body is evenly equipped with that several are protruding, forms a groove between two projections of arbitrary neighborhood, groove and pin with the use of, in order to prevent nut loosening, but, protruding with groove fit during, it is easily deformed, causes slotted nut to damage；Meanwhile, the groove in existing slotted nut often makes plane, causes it with pin engagement process, and pin easily loosens, and then reduces stability when nut fastens.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is the nut providing a kind of structural strength big.

For achieving the above object, this utility model provides following technical scheme: nut, including nut body, nut body is provided with axis hole, nut body includes cylinder and is set in the intensive aspect of cylindrical outer, the exterior contour of intensive aspect is positive hexa-prism, described nut body is provided with some bar-shaped troughs of through nut body outer wall and axis hole hole wall, it is 60 degree that two bar-shaped troughs of arbitrary neighborhood intersect formed sharp angle, described axis hole includes installing hole and the screwed hole being interconnected, and the degree of depth of described installing hole is identical with the depth capacity of bar-shaped trough.

Further, described bar-shaped trough includes the first side, the second side and bottom surface, and the first side is connected with bottom surface respectively with the second side, and described bottom surface includes first and second, and first intersects with second, and angulation is 90 degree.

Further, the centrage of each bar-shaped trough intersects at a point.

Further, the aperture of described installing hole is more than the aperture of screwed hole.

Further, the depth capacity of described bar-shaped trough and cylindrical high ratio are 1:3.

Further, the curved shape in described bottom surface.

Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that this utility model provides is brought: 1. by offering some bar-shaped troughs on nut body, and each bar-shaped trough through nut body outer wall and axis hole hole wall, such design, protruding wall thickness between adjacent two bar-shaped troughs is increased, prevent the phenomenon that projection deforms, add structural strength, simultaneously, in order to not make nut body structural strength after grooving reduce, the depth capacity of bar-shaped trough and cylindrical high ratio are 1:3.2. for the phenomenon preventing pin from loosening during coordinating with bar-shaped trough, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough adaptation, therefore, pin is all laminating during installing with each face (the first side, the second side, first and the second face) of bar-shaped trough, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.3. in order to prevent the phenomenon got rusty between nut and bolt, the aperture of the ratio screwed hole set in the aperture of described installing hole is big, therefore, produces oil storage gap between installing hole and bolt, and by bar-shaped trough oil addition.

Detailed description of the invention

With reference to Fig. 1-Fig. 4, this utility model is described further.

Embodiment 1

Nut, including nut body 1, nut body 1 is provided with axis hole 11, nut body 1 includes cylinder 12 and is set in the intensive aspect 13 outside cylinder 12, the exterior contour of intensive aspect 13 is positive hexa-prism, the height of intensive aspect 13 is essentially identical with the height of cylinder 12, described nut body 1 is provided with some bar-shaped troughs 14 of through nut body 1 outer wall and axis hole 11 hole wall, it is 60 degree that two bar-shaped troughs 14 of arbitrary neighborhood intersect formed sharp angle, described axis hole 11 includes installing hole 111 and the screwed hole 112 being interconnected, the degree of depth of described installing hole 111 is identical with the depth capacity of bar-shaped trough 14.

By offering some bar-shaped troughs 14 on nut body 1, and each bar-shaped trough 14 through nut body 1 outer wall and axis hole 11 hole wall, such design, protruding wall thickness between adjacent two bar-shaped troughs 14 is increased, prevent the phenomenon that projection deforms, add structural strength, simultaneously, in order to not make nut body 1 structural strength after grooving reduce, the depth capacity of bar-shaped trough 14 is 1:3 with the high ratio of cylinder 12.

Described bar-shaped trough 14 includes the 141, second side 142 and bottom surface, the first side, first side 141 is connected with bottom surface respectively with the second side 142, described bottom surface includes the first face 143 and the second face 144, and the first face 143 is intersected with the second face 144, and angulation is 90 degree.

For the phenomenon preventing pin from loosening during coordinating with bar-shaped trough 14, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough 14 adaptation, therefore, pin is all laminating during installing with each face (the 142, first face, the 141, second side, the first side 143 and the second face 144) of bar-shaped trough 14, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.

First side 141 is parallel with the second side 142, describe for convenience, the line marking C in Fig. 1 is defined as the centrage of bar-shaped trough 14, it is 60 degree that the centrage of the two of arbitrary neighborhood bar-shaped troughs 14 intersects formed sharp angle, the number of bar-shaped trough 14 is 6, and the centrage of the most each bar-shaped trough 14 intersects at a point, therefore, pin can turn on two relative bar-shaped troughs 14, and stability is more increased.

In order to prevent the phenomenon got rusty between nut and bolt, the aperture of the ratio screwed hole 112 set in the aperture of described installing hole 111 is big, therefore, produces oil storage gap between installing hole 111 and bolt, and by bar-shaped trough 14 oil addition.

Embodiment 2

The present embodiment is substantially the same manner as Example 1, unique unlike: the curved shape in described bottom surface.

For the phenomenon preventing pin from loosening during coordinating with bar-shaped trough 14, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough 14 adaptation, therefore, pin is all laminating during installing with each face (the 141, second side 142, the first side and the bottom surface of arc shape) of bar-shaped trough 14, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, those skilled in the art carries out common variations and alternatives in the range of technical solutions of the utility model and should be included in protection domain of the present utility model.
