Embodiment Construction

[0014]SeeFigure 1 to Figure 9, First tighten the nut B6 on the bolt 11 and make the lower end of the nut B6 press the workpiece 12 with its truncated cone-shaped face upwards, and then screw the extrusion part 3 of the nut A1 downwards on the bolt 11, in the nut A1 During the tightening process, the multiple ribs A4 of the nut A1 and the multiple ribs B10 of the nut B6 are in close contact with each other, and the nut A1 is tightened. The arc surface A17 of the multiple ribs A4 of the nut A1 and the nut B6 are more The arc surface B15 of the rib B10 is first squeezed and elastically compressed. When the arc surface A17 of the multiple ribs A4 of the nut A1 crosses the arc surface B15 of the corresponding multiple ribs B10 of the nut B6, the nut The multiple ribs A4 of A1 and the multiple ribs B10 of the nut B6 elastically recover again. At this time, the plane B16 at the lower end of the multiple ribs B10 of the nut B6 presses the plane A14 of the upper end of the multiple ribs A4 o...

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 mechanical field or construction field, and is particularly suitable for fixing components that frequently vibrate.Background technique[0002]The currently used or patented locknuts cannot be interlocked, and eventually the nut will loosen from the bolt. Although some nuts have the function of preventing loosening and locking, they need additional accessories, which is inconvenient to manufacture and use.Summary of the invention[0003]The present invention solves the above problems. It has an interlocking function, the tightened nut will not loosen from the bolt, and no additional accessories are needed. It is convenient to manufacture and use; it is composed of nut A (1) and nut B (6). ; Nut A (1) is composed of screw body A (2), extrusion part (3), and multiple ribs A (4). Screw body A (2) has internal thread A (5) and internal thread A (5) ) Is consistent with the external thread of the bolt (11), the lo...
