Embodiment Construction

[0016] see Figure 1 to Figure 11 , first explain the arrangement of a plurality of strip-shaped 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. The radius of the imaginary circle A18 of the center point of the inner surface of the frustum of a cone formed by two clips 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 nut 1 The outer surface of the truncated cone of the extrusion part 3 is arranged within the range corresponding to the arc length C of the clip 17. M convex ribs 4 are arranged, and the virtual circle B19 of the upper and lower center points on the outer surface of the truncated cone of the extrusion part 3 of the nut 1 The radius is R', when the nut 1 and the bolt 16 are processed, R=R', although R=R' here, when the multiple strip-shaped ribs 4 of the extruded part 3 of the nut ...

Abstract

The invention discloses interlockable lock bolt and nut, which are mainly applied in the field of machinery. The interlockable lock bolt and nut have an interlocking function, the tightened nut is notdisconnected with the bolt, and manufacturing and use are facilitated; the interlockable lock bolt and nut consists of the nut and the bolt; the working principle is as follows: an extrusion part ofthe nut is screwed tightly and downwards on the bolt, the lower end of the nut tightly presses a workpiece, a plurality of convex ribs of the extrusion part of the nut extrude a plurality of clampingsheets of the bolt, the external threads of a plurality of clamping sheets extrude the internal threads of the nut, and the locking aim is fulfilled; if the convex rib at the uppermost end of the nutaligns with the groove at the uppermost end of the bolt exactly, at least one convex rib is clamped in the groove of the bolt and interlocking is realized; and if the convex rib at the uppermost end of the nut does not align with the groove at the uppermost end of the bolt, the nut is continuously rotated clockwise or anticlockwise by the distance of 1 / 8 B or the distance of 1 / 4 B or the distanceof 1 / 2 B, at least one convex rib is clamped into the groove of the bolt, and interlocking is realized.

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...
