Embodiment Construction

[0014] see Figure 1 to Figure 9 , 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 convex ribs A4 of the nut A1 and the multiple convex ribs B10 of the nut B6 are tightly attached to each other, and the nut A1 is continued to be tightened, the arc surface A 17 of the multiple convex ribs A4 of the nut A1 and the multiple convex ribs B10 of the nut B6 are in close contact with each other. The arc surface B15 of the convex rib B10 is first extruded and elastically compressed, and when the arc surface A17 of the plurality of convex ribs A4 of the nut A1 passes down the arc surface B15 of the corresponding plurality of convex ribs B10 of the nut B6, the nut The multiple convex ribs A4 of A1 and the multiple convex ribs B10 of the nut B6 undergo elastic r...

Abstract

The invention discloses a locknut capable of clamping and capable of interlocking, and is mainly used in the field of machinery. The locknut has an interlocking function, and is simple to manufactureand is convenient to use. The locknut is composed of a nut A and a nut B; the working principle of the locknut comprises the steps that the nut B is tightly screwed on a bolt firstly, and the lower end of the nut B is pressed against a workpiece; then an extruding part of the nut A is faced downwards and is screwed on the bolt; a plurality of protruding ribs A of the nut A and a plurality of protruding ribs B of the nut B are extruded firstly to generate elastic compression; the plurality of protruding ribs A of the nut A go over the corresponding plurality of protruding ribs B of the nut B downwards, and then the plurality of protruding ribs A of the nut A and the plurality of protruding ribs B of the nut B are elastically restored; and at the moment, the lower ends of the plurality of protruding ribs B of the nut B presses the upper ends of the plurality of protruding ribs A of the nut A, the nut A and the nut B realize interlocking, the extruding part of the nut A extrudes a plurality of arc segments of the nut B at the same time, and internal threads B of the plurality of arc segments extrude external threads of the bolt to hoop the external threads of the bolt tightly, so thatthe purpose of locking 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 problems. It has an interlocking function. After tightening, the nut will not be loosened from the bolt, and no additional accessories are needed. It is easy to manufacture and use; it consists of nut A (1) and nut B (6). ; Nut A (1) is composed of screw body A (2), extruded part (3) and multiple convex ribs A (4), screw body A (2) has internal thread A (5), internal thread A (5 ) coincides with the external thread o...
