Embodiment Construction

[0012] see Figure 1 to Figure 7 , first tighten the nut B6 on the bolt 11 and press the lower end of the nut B6 against the workpiece 12 with the small surface of the truncated cone facing upwards, then screw the extruded part 3 of the nut A1 downwards on the bolt 11. During the tightening process, the multiple ribs A4 of the nut A1 and the multiple ribs B10 of the nut B6 are tightly attached to each other, and the nut A1 is continued to be tightened, the semicircular surface of the multiple ribs A4 of the nut A1 and the multiple ribs B10 of the nut B6 The semi-arc surfaces of the convex ribs B10 are squeezed first to be elastically compressed, and when the semi-arc surfaces of the plurality of ribs A4 of the nut A1 pass down the semi-arc surfaces of the corresponding plurality of ribs B10 of the nut B6, the The semi-arc surfaces of the plurality of convex ribs A4 and the plurality of convex ribs B10 of the nut B6 undergo elastic recovery again. At this time, the lower ends o...

Abstract

The invention discloses an interlocking reusable locknut mainly applied to the mechanical field; the interlocking reusable locknut has an interlocking function, and can further exit for reutilization;the interlocking reusable locknut is composed of a nut A and a nut B; according to the working principle of the interlocking reusable locknut, the nut B is firstly tightened on a bolt so that a workpiece is pressed by the lower end of the nut B, and then the nut A is tightened on the bolt with the extrusion portions facing downwards; a plurality of convex ribs of the nut A and a plurality of convex ribs of the nut B are firstly extruded and compressed elastically; after the multiple convex ribs of the nut A get across the corresponding multiple convex ribs of the nut B, the multiple convex ribs of the nut A and the multiple convex ribs of the nut B are restored elastically; at the moment, the upper ends of the multiple convex ribs of the nut A are pressed by the lower ends of the multipleconvex ribs of the nut B, and interlocking between the nut A and the nut B is achieved; meanwhile, a plurality of arc segments of the nut B are extruded by the extrusion portions of the nut A, and external threads of the bolt are extruded by internal threads B of the multiple arc segments, so that the external threads of the bolt are tightly clamped, and the purpose of anti-looseness is achieved.

Description

technical field [0001] The invention is mainly used for fixing components in the field of machinery or construction, and is especially suitable for fixing components that often vibrate. Background technique [0002] The currently used or patented anti-loosening nuts cannot be interlocked, and eventually the nut will be loosened from the bolt; although some nuts have an anti-loosening locking function, additional accessories need to be added, which is inconvenient to manufacture and use. Contents of the invention [0003] The present invention solves the above-mentioned problems. It has an interlocking function. After tightening, the nut will not loosen from the bolt, and no additional parts need to be added. It is convenient to manufacture and use, and the nut can also be withdrawn for reuse; ), nut B (6); nut A (1) is composed of screw body A (2), extruded part (3), and multiple convex ribs A (4), and screw body A (2) has internal thread A ( 5), the internal thread A (5)...
