Embodiment Construction

[0009] see Figure 1 to Figure 4 , 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, since the pitch and profile angle of the internal thread section 4 of the extrusion part 3 of the nut A1 are different from the pitch and profile angle of the external thread section 10 of the nut B6, the multiple internal threads of the nut A1 The threaded section 4 and the multiple external threaded sections 10 of the nut B6 are extruded and engaged together, and at the same time, the lower end of the nut A1 is pressed against the workpiece 12, and the nut B6 is completely wrapped in the extrusion part 3 of the nut A1. The nut A1 and the nut B6 Interlocking is realized, and at the same time, since the inclination of the inner surface of the extruded part 3 of the nut A1 is larger...

Abstract

The invention discloses a thread dislocation type lock nut mainly used in the field of machinery. The lock nut has an interlocking function, is convenient to manufacture and use, and comprises a nut body A and a nut body B. According to the working principle, the nut body B is screwed on a bolt, then an extrusion part of the nut body A is screwed on the bolt downwards, and in the screwing processof the nut body A, the pitch and tooth angle of internal thread sections of the extrusion part of the nut body A are different from those of external thread sections of the nut body B, so that the internal thread sections of the nut body A and the external thread sections of the nut body B are extruded and meshed. Meanwhile, the lower end of the nut body A abuts against a workpiece, the nut body Aand the nut body B are interlocked, the extrusion part of the nut body A extrudes multiple arc sections of the nut body B, internal threads B of the arc sections extrude external threads of the bolt,and the external threads of the bolt are tightly hooped, so that friction between the internal threads B of the arc sections and the external threads of the bolt is greatly improved, and the anti-disengaging aim 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 internal thread segments (4), screw body A (2) has internal thread A (5), internal thread A (5 ) coincides with the extern...
