Embodiment Construction

[0016] see Figure 1 to Figure 11 , first explain the arrangement of a plurality of ribs 4 of the nut 1, assuming that the number of clips 17 of the bolt 16 is N, and N is an even number, the number of the same groove 9 is also N, and the width of the groove 9 is A, and a plurality of clips The radius of the imaginary circle A18 at the center point of the inner surface of the truncated cone formed by the piece 17 is R, and the average arc length of each clip 17 is C, then C=2∏R / N-A, and it is assumed that the extrusion of the nut 1 The outer surface of the truncated cone of part 3 corresponds to the arrangement of M convex ribs 4 within the scope of the arc length C of the clip 17, and the radius of the virtual circle B19 at the upper and lower center points on the outer surface of the truncated cone of the extruded part 3 of the nut 1 is R', when the nut 1 and the bolt 16 are processed, R=R', when the plurality of ribs 4 of the extruded part 3 of the nut 1 are in close contac...

Abstract

The invention discloses interlockable anti-loosening bolts and nuts, which are mainly used in the mechanical field; it has an interlocking function, and the tightened nuts will not be loosened from the bolts, and is easy to manufacture and use; it is composed of nuts and bolts; The working principle is: tighten the extruded part of the nut downwards on the bolt and press the lower end of the nut against the workpiece. The outer thread of the piece squeezes the inner thread of the nut to achieve the purpose of anti-loosening; if the uppermost rib of the nut is just aligned with the uppermost groove of the bolt, then at least one rib is stuck in the groove of the bolt to achieve interlocking ;If the uppermost rib of the nut is not aligned with the uppermost groove of the bolt, continue to turn the nut clockwise or counterclockwise one-eighth of the distance of B or one-quarter of the distance of B or one-half of the distance of B, Also, at least one rib is snapped into the groove of the bolt to realize interlocking.

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, and the nut after tightening will not loosen from the bolt, and does not need to add additional accessories. It is easy to manufacture and use; it consists of a nut (1) and a bolt (16); the nut (1) It is composed of screw body (2), extruded part (3), convex rib (4), and head (6). The screw body (2) has internal thread (5), and the internal thread (5) is connected wi...
