Abstract
The invention discloses a fastening component comprising a bolt and a nut. The nut is fixed on the bolt in a threaded manner. The nut comprises a first nut part and a second nut part. The outer side of the first nut part is provided with a first slant which is provided with a circular groove. The inner side of the second nut part is provided with a second slant which is provided with a projection. The first slant is as tapered as the second slant. The projection is inserted into the circular groove to integrate the first and second nut parts. According to the scheme, when the first nut part loosens and rotates, the projection slides in the circular groove, thus rotation of the second nut part is prevented; the second nut part does not rotate, rotation tendency of the first nut part can be stopped by the second nut part so that the first nut cannot rotate, and accordingly nut loosening is prevented.
Description
Technical field
The present invention 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, usually adopt the different fastener of bolt assembly fastening two, common bolt assembly, comprise bolt, nut; The end of described nut is straight.During use, bolt passes 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, in time carry out fasteningly, carry out trouble-saving generation.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, fastener assembly that can prevent nut loosening.
For achieving the above object, the technical solution used in the present invention is: a kind of fastener assembly comprises bolt, nut; But described nut screw thread is fixed on bolt; Described nut, comprise 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 inboard 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; Described projection is inserted in circular trough and is made the first nut portions and the second nut portions form an integral body.
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 present invention compared with prior art has following advantages:
Fastener assembly of the present invention, described nut, comprise the first nut portions, the second nut portions; On described the second inclined-plane, projection is inserted on the first inclined-plane and in circular trough, is made the first nut portions and the second nut portions form an integral body; 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 the first nut portions has the trend of rotation, also can be stoped by the second nut portions, and can not rotate, thereby realization prevents the purpose of nut loosening.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of fastener assembly of the present invention;
Accompanying drawing 2 is the application state schematic diagram of fastener assembly of the present invention;
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
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is a kind of fastener assembly of the present invention, comprises bolt 3, nut; But described nut screw thread is fixed on bolt 3; Described nut, comprise the first nut portions 1, the second nut portions 2; The arranged outside of described the first nut portions 1 has the first inclined-plane (not marking), on described the first inclined-plane, is provided with circular trough (not marking); The inboard of described the second nut portions 2 is provided with the second inclined-plane (not marking); On described the second inclined-plane, be provided with projection 12; Described the first inclined-plane is consistent with the gradient on the second inclined-plane; In described protruding 12 insertion circular troughs, make the first nut portions 1 and 2 ones, the second nut form integral body; On described the second inclined-plane, be provided with equably skewed slot 11; The true dip direction of described skewed slot 11 is consistent.
As shown in Figure 2, during use, bolt 3 passes the first fastener 4, the second fastener 5 successively; Between described the first fastener 4, the second fastener 5, be provided with packing ring 6; On described the second inclined-plane, on projection 12 insertion the first inclined-planes, in circular trough, making the first nut portions 1 and the second nut portions 2 form integral body is nut; Nut thread is fixed on bolt 3.
Fastener assembly of the present invention, described nut, comprise the first nut portions, the second nut portions; On described the second inclined-plane, projection is inserted on the first inclined-plane and in circular trough, is made the first nut portions and the second nut portions form an integral body; 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 the first nut portions has the trend of rotation, also can be stoped by the second nut portions, and can not rotate, thereby realization prevents the purpose of nut loosening; The setting of described skewed slot is the resistance for the mutual rotation that increases the first inclined-plane and the second inclined-plane, increases the difficulty that relative the second nut portions of the first nut portions rotates.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
1. a fastener assembly, comprise bolt, nut; But described nut screw thread is fixed on bolt; Described nut, comprise 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 inboard 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; Described projection is inserted in circular trough and is made the first nut portions and the second nut portions form an integral body.
2. fastener assembly according to claim 1, is characterized in that: on described the second inclined-plane, be provided with equably skewed slot.
3. fastener assembly according to claim 2, it is characterized in that: the true dip direction of described skewed slot is consistent.
