Abstract
The invention discloses a lock nut, which comprises a nut body. A threaded hole is arranged at the center of the nut body, a groove is arranged on the inner wall of the threaded hole, and one end of the groove is tangent to the threaded hole. According to the lock nut, the groove is arranged on the inner wall of the threaded hole, one end of the groove is tangent to the threaded hole, when the nut is tightened on a bolt, a steel wire can be inserted in the groove to lead the nut to perform a clockwise rotation merely, when the nut performs a counterclockwise rotation, the steel wire can be brought out of the groove, and a frictional force of the counterclockwise motion of the nut is increased, and thereby the looseness of the lock nut can be prevented.
Description
Technical field
The present invention relates to a kind of improvement of nut structure, especially relate to a kind of lock nut that prevents nut loosening that has, belong to the securing means technical field.
Background technique
In the existing technology, two fasteners are realized the fixing of two fasteners through bolt, nut, pad also together usually; This means of fixation relatively is fit to state of rest, if, when two fasteners are in vibrational state, then can be owing to the effect of vibration, loosening the coming that nut can be slowly causes two fasteners to break away from tightening states, causes security incident.
Summary of the invention
The present invention seeks to provides a kind of lock nut that prevents nut loosening that has for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the present invention adopts is: a kind of lock nut comprises nut body; The center of said nut body has been located at tapped hole; The inwall of said tapped hole is provided with groove; One end and the tapped hole of said groove are tangent.
Beneficial effect of the present invention is mainly reflected in: lock nut of the present invention; The inwall of tapped hole is provided with groove, and an end and the tapped hole of said groove are tangent, when nut be screwed in tighten on the bolt after; In groove, insert a steel wire, nut can only be turned clockwise; And when nut was rotated counterclockwise, steel wire can be taken out of from groove, increased the nut frictional force of motion counterclockwise, reached to stop the loosening of nut.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of lock nut of the present invention;
Accompanying drawing 2 is a lock nut application state schematic representation of the present invention;
Wherein: 1, first fastener; 2, second fastener; 3, bolt; 4, lock nut; 5, pad; 6, nut body; 7, groove; 8, steel wire; 9, tapped hole.
Embodiment
Of the present invention a kind of lock nut 4 shown in accompanying drawing 1 comprises nut body 6; The center of said nut body 6 has been located at tapped hole 9; The inwall of said tapped hole 9 is provided with groove 7; One end and the tapped hole 9 of said groove 7 are tangent.
Be depicted as the nut application state schematic representation that loosens of the present invention like accompanying drawing 2; Said first fastener 1 is arranged on second fastener 2; Said bolt 3 passes second fastener 2, first fastener 1; Said pad 5 passes the upper surface that bolt 3 is arranged on first fastener 2; Said lock nut 4 screw threads are fixed on the bolt 3, and compress gasket 5; A steel wire 8 inserts in the groove 7; Lock nut 4 can only be turned clockwise; And when lock nut 4 was rotated counterclockwise, steel wire 8 can be taken out of from groove 7, increased lock nut 4 frictional force of motion counterclockwise, reached to stop the loosening of lock nut 4.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
