Abstract
The utility model relates to a fastening assembly. The fastening assembly comprises a bolt and a nut, wherein the nut is fixed to the bolt in a threaded mode. The nut comprises a first nut part and a second nut part, wherein a first inclined surface is arranged at the outer side of the first nut part and provided with a round groove, a second inclined surface is arranged at the inner side of the second nut part and provided with a protrusion, the inclined degree of the first inclined surface and the inclination degree of the second inclined surface are consistent, and the protrusion is inserted into the round groove so that the first nut part and the second nut part can form a whole. According to the technical scheme, when the first nut part rotates due to looseness, the protrusion will slide in the round groove, and the second nut part is prevented from rotating. Due to the fact that the second nut part does not rotate, even though the first nut part has the tendency of rotation, the first nut part is blocked by the second nut part and can not rotate, and the purpose of preventing looseness of the nut is achieved.
Description
Technical field
The utility model relates to a kind of improvement of fastening piece, especially a kind of simple in structure, fastener assembly that can prevent nut loosening.
Background technique
In prior art, conventionally adopt the fastening two different fasteners of bolt assembly, common bolt assembly, comprises bolt, nut; The end of described nut is straight.During use, bolt is through two different fasteners, and the nut of then screwing on, tightens together two different fasteners; Due to generally, fastener in use all can produce vibrations, and service time one is long, nut can become flexible and come along screw thread from bolt, and existing remedial measure is by making regular check on bolt assembly, if find that nut send part, carry out in time fasteningly, carry out trouble-saving generation.
Model utility content
The utility model object is that a kind of simple in structure, fastener assembly that can prevent nut loosening is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fastener assembly, comprises bolt, nut; Described nut can be fixed on bolt by screw thread; Described nut, comprises the first nut portions, the second nut portions; The arranged outside of described the first nut portions has the first inclined-plane, on described the first inclined-plane, is provided with circular trough; The inner side of described the second nut portions is provided with the second inclined-plane; On described the second inclined-plane, be provided with projection; Described the first inclined-plane is consistent with the gradient on the second inclined-plane; In described projection insertion circular trough, make the first nut portions and the second nut portions shape in aggregates.
Preferably, on described the second inclined-plane, be provided with equably skewed slot.
Preferably, the true dip direction of described skewed slot is consistent.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Fastener assembly described in the utility model, described nut, comprises the first nut portions, the second nut portions; Described the second inclined-plane projection insert on the first inclined-plane, in circular trough, make the first nut portions and the second nut portions shape in aggregates; When the first nut portions produces rotation because becoming flexible, described projection can be skidded in circular trough, can prevent the second nut portions rotation, because the second nut portions does not rotate, even if the first nut portions has the trend of rotation, also can be stoped by the second nut portions, and can not rotate, thereby realize the object that prevents nut loosening.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is fastener assembly described in the utility model;
The application state schematic diagram that accompanying drawing 2 is fastener assembly described in the utility model;
Wherein: 1, the first nut portions; 2, the second nut portions; 3; Bolt; 4, the first fastener; 5, the second fastener; 6, packing ring; 11, skewed slot; 12, projection.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 2, during use, bolt 3 is successively through the first fastener 4, the second fastener 5; Between described the first fastener 4, the second fastener 5, be provided with packing ring 6; On described second inclined-plane projection 12 insertion the first inclined-planes, in circular trough, making the first nut portions 1 and the second nut portions 2 shapes in aggregates is nut; Nut thread is fixed on bolt 3.
Fastener assembly described in the utility model, described nut, comprises the first nut portions, the second nut portions; Described the second inclined-plane projection insert on the first inclined-plane, in circular trough, make the first nut portions and the second nut portions shape in aggregates; When the first nut portions produces rotation because becoming flexible, described projection can be skidded in circular trough, can prevent the second nut portions rotation, because the second nut portions does not rotate, even if the first nut portions has the trend of rotation, also can be stoped by the second nut portions, and can not rotate, thereby realize the object that prevents nut loosening; The setting of described skewed slot is in order to increase the resistance of the mutual rotation on the first inclined-plane and the second inclined-plane, increases the difficulty that relative the second nut portions of the first nut portions rotates.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
Claims (3)
1. a fastener assembly, comprises bolt, nut; Described nut can be fixed on bolt by screw thread; Described nut, comprises the first nut portions, the second nut portions; The arranged outside of described the first nut portions has the first inclined-plane, on described the first inclined-plane, is provided with circular trough; The inner side of described the second nut portions is provided with the second inclined-plane; On described the second inclined-plane, be provided with projection; Described the first inclined-plane is consistent with the gradient on the second inclined-plane; In described projection insertion circular trough, make the first nut portions and the second nut portions shape in aggregates.
