Description
Technical field
This utility model relates to lock nut technical field, is specially a kind of lock 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 lock nut providing a kind of structural strength big.
For achieving the above object, this utility model provides following technical scheme: a kind of lock nut, it is the lock nut body of cylindrical shape including exterior contour, it is provided with axis hole at the axial line of lock nut body, described lock nut body is provided with some bar-shaped troughs of through lock 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, the degree of depth of described installing hole is identical with the depth capacity of bar-shaped trough, the outer wall of described lock nut body is symmetrically arranged with the first plane and the second plane, first plane is parallel with the second plane.
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 lock nut body, and each bar-shaped trough through lock nut body outer wall and axis hole hole wall, such design, make the protruding wall thickness between adjacent two bar-shaped troughs thicker, and form an entirety with lock nut body, prevent the phenomenon that projection deforms, add structural strength, simultaneously, in order to not make lock 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 lock 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 lock nut is fixed reduces.3. in order to prevent the phenomenon got rusty between lock 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
A kind of lock nut, it is the lock nut body 1 of cylindrical shape including exterior contour, axis hole 11 it is provided with at the axial line of lock nut body 1, described lock nut body 1 is provided with some bar-shaped troughs 12 of through lock nut body 1 outer wall and axis hole 11 hole wall, it is 60 degree that two bar-shaped troughs 12 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 12, the outer wall of described lock nut body 1 is symmetrically arranged with the first plane 13 and the second plane 14, first plane 13 is parallel with the second plane 14, conveniently utilize other fastening instrument that lock nut carries out rotation fixing.
By offering some bar-shaped troughs 12 on lock nut body 1, and each bar-shaped trough 12 through lock nut body 1 outer wall and axis hole 11 hole wall, such design, make the protruding wall thickness between adjacent two bar-shaped troughs 12 thicker, and form an entirety with lock nut body 1, prevent the phenomenon that projection deforms, add structural strength, meanwhile, in order to not make lock nut body 1 structural strength after grooving reduce, the depth capacity of bar-shaped trough 12 and cylindrical high ratio are 1:3.
Further, described bar-shaped trough 12 includes the 121, second side 122 and bottom surface, the first side, and the first side 121 is connected with bottom surface respectively with the second side 122, and described bottom surface includes the first face 123 and the second face 124, first face 123 is intersected with the second face 124, and angulation is 90 degree.
For the phenomenon preventing pin from loosening during coordinating with bar-shaped trough 12, occur also for the phenomenon preventing the solid timing stability of lock nut from reducing, pin and bar-shaped trough 12 adaptation, therefore, pin is all laminating during installing with each face (the 122, first face, the 121, second side, the first side 123 and the second face 124) of bar-shaped trough 12, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when lock nut is fixed reduces.
First side 121 is parallel with the second side 122, describe for convenience, the line marking C in Fig. 1 is defined as the centrage of bar-shaped trough 12, it is 60 degree that the centrage of the two of arbitrary neighborhood bar-shaped troughs 12 intersects formed sharp angle, the number of bar-shaped trough 12 is 6, and the centrage of the most each bar-shaped trough 12 intersects at a point, therefore, pin can turn on two relative bar-shaped troughs 12, and stability is more increased.
In order to prevent the phenomenon got rusty between lock 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 12 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 12, occur also for the phenomenon preventing the solid timing stability of lock nut from reducing, pin and bar-shaped trough 12 adaptation, therefore, pin is all laminating during installing with each face (the 121, second side 122, the first side and the bottom surface of arc shape) of bar-shaped trough 12, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when lock 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.
