Through adopting above-mentioned technical scheme, with nut body screw in bolt for first internal thread aligns with the internal thread line of second, supports the extrusion force extrusion flexure strip that the piece received the bolt this moment, makes the flexure strip produce elastic deformation, and the flexure strip produces the reaction force simultaneously and promotes first internal thread and the internal thread of second and push up tightly each other, can let the bolt firmly fix inside the nut body.
The utility model discloses further set up to: the top surface of the nut body is provided with a first gasket.
Through adopting above-mentioned technical scheme, twist the bolt until first packing ring top tight object surface, first packing ring received the pressure on nut body top surface and object surface this moment and produced elastic deformation, and first packing ring produces the reaction force simultaneously and promotes the nut body and keep away from the object surface for the internal thread side of nut body supports tightly with the external screw thread side of bolt, makes the antiskid effect that has of nut body, makes bolt and nut body connection inseparabler.
The utility model discloses further set up to: the top surface of the first gasket is provided with a second gasket, and the second gasket is fixedly connected to the peripheral wall of the first gasket through an elastic piece.
Through adopting above-mentioned technical scheme, when the elastic component received the extrusion, the elastic component produced elastic deformation, promoted the tight object surface in second packing ring top and made it be difficult for receiving exogenic action such as vibrations and the reversal pine takes off.
The utility model discloses further set up to: the elastic piece is U-shaped.
Through adopting above-mentioned technical scheme for elastic deformation takes place more easily for the elastic component.
The utility model discloses further set up to: the first gasket, the second gasket and the elastic piece are integrally formed.
Through adopting above-mentioned technical scheme, make first packing ring, second packing ring and elastic component three be difficult to the fracture.
The utility model discloses further set up to: the first washer, the second washer and the elastic piece are made of spring steel.
By adopting the technical scheme, the first gasket, the second gasket and the elastic piece can bear certain load, and permanent deformation does not occur after the load is removed.
To sum up, the utility model discloses following beneficial effect has: the nut body is screwed into the bolt, so that the thread lines of the first internal thread and the second internal thread are aligned, the elastic piece is extruded by the extrusion force of the bolt to generate elastic deformation, and meanwhile, the elastic piece generates a reaction force to push the abutting piece to jack the bolt, so that the bolt can be firmly fixed in the nut body. The first internal thread and the second internal thread are positioned on the same thread line, so that the abutting of the abutting block and the bolt is very tight.
