Abstract
A lock nut of elastic deformation type is prepared as opening slot at radial place of nut, setting surface pressing work piece to be a slope with slot, deforming slope backwards elastically to form an elastic force between nut and work piece and an axial pressing force between nut and screw when work piece is pressed strongly by nut and screw for making nut and screw not be easy to loose when vibration and alternating load are occurred on them.
Description
The present invention relates to and be used to prevent that workpiece from becoming flexible and the nut of connection.
Existing nut is processed with screw thread in endoporus, the bolt that corresponding screw thread is arranged is passed the hole of clamped workpiece after, use nut screwing clamping, by the distortion of screw thread and friction workpiece is clamped.Because clamped workpiece is subjected to vibration, impact force or other factors influence sometimes, makes nut loosening, influences the loosening of workpiece.
Purpose of the present invention just provides a kind of resiliently deformable formula lock nut of becoming flexible of preventing.
In order to reach above purpose, resiliently deformable formula lock nut of the present invention is made up of nut.Nut radially has trough in the working surface certain distance position of tripping clamping of workpieces, and the working surface of workpiece pressing is inside by the screw thread place, and outer circle place outwards makes that the surface of contact of beginning workpiece pressing is the outer end.Because the surface of contact of workpiece pressing is the outer end, nut radially has trough, and when nut rotatably compressed, nut and workpiece contacting point will produce resiliently deformable backward.
After adopting above method, after compressing at nut, nut front produces resiliently deformable backward, the screw thread of nut and screw rod is subjected to responsive to axial force, frictional force between the screw thread increases, and when being pressed workpiece to be subjected to vibration, impact force or other factors influence, nut is difficult to take place to become flexible.
With drawings and Examples resiliently deformable formula lock nut of the present invention is described further below.
Accompanying drawing 1 is resiliently deformable formula lock nut first embodiment's part sectional view of the present invention.
Accompanying drawing 2 is resiliently deformable formula lock nut first embodiment's part plan view of the present invention.
Accompanying drawing 3 is resiliently deformable formula lock nut second embodiment's part sectional view of the present invention.
Accompanying drawing 4 is resiliently deformable formula lock nut the 3rd embodiment's part sectional view of the present invention.
Accompanying drawing 5 is resiliently deformable formula lock nut the 3rd embodiment's part plan view of the present invention.
In accompanying drawing 1 and accompanying drawing 2 first embodiments, nut is processed into the conical surface radially having a groove at end face, has groove along the conical surface.
In second embodiment of accompanying drawing 3, it different with first embodiment three be in: end face has a facet.
In the 3rd embodiment of accompanying drawing 4 and accompanying drawing 5, it and first embodiment's difference are: the groove of opening vertically is up to the other end of nut.
The present invention only has only above several structure, more than several textural associations also for content of the present invention.
Claims (1)
1, a kind of resiliently deformable formula lock nut, it is characterized in that: nut radially has trough, and end face is an inclined-plane, has groove on the inclined-plane.
