Abstract
The utility model relates to 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, and the end of the groove is tangent to the threaded hole, so that when the nut is tightly screwed on a bolt, the nut can only rotate clockwise by inserting a steel wire in the groove; when the nut rotates anticlockwise, the steel wire is driven to drop from the groove, and friction forces of anticlockwise motion of the nut are increased so as to achieve the purpose of preventing the lock nut from loosening.
Description
Technical field
The utility model relates to a kind of improvement of nut structure, especially relates to a kind of lock nut that prevents nut loosening that has, and belongs 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.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology a kind of lock nut that prevents nut loosening that has to be provided.
For achieving the above object, the technological scheme that the utility model 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.
The beneficial effect of the utility model is mainly reflected in: the described lock nut of the utility model; 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 the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the described lock nut of the utility model;
Accompanying drawing 2 is the described lock nut application state of a utility model schematic representation;
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
The described a kind of lock nut 4 of the utility model 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 described nut application state schematic representation that loosens of the utility model 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
