Anti-loose nut capable of being interlocked

Abstract

The invention discloses an anti-loose nut capable of being interlocked. The anti-loose nut is mainly applied to the field of machinery. The anti-loose nut capable of being interlocked has an interlocking function, the tightened nut cannot be loosened from a bolt, and the nut is convenient to manufacture and use. The anti-loose nut is composed of a nut body A and a nut body B; according to the working principle of the anti-loose nut, first an extruding part of the nut body A is upwards screwed up on the bolt, the lower end of the nut body A presses a workpiece, then a clamping part of the nut body B is downwards screwed on the bolt, moreover, the clamping part of the nut body B abuts against the extruding part of the nut body A, a plurality of convex ribs of the extruding part of the nut body A are used for extruding a plurality of clamping pieces of the nut body B, inner threads B of the plurality of clamping pieces are used for extruding outer threads of the bolt to tightly hoop the external threads of the bolts, and the purpose of preventing looseness is achieved. According to the anti-loose nut, at least one convex rib is clamped into a groove of the nut body B in the process, so that interlocking is realized; under the action of the vibration load, the nut body B is loosened first, the convex rib clamped in the groove of the nut body B is used for preventing the nut body Bfrom loosening, at the same time, the plurality of convex ribs tightly hoop the external threads of the bolt, so that the purpose of preventing looseness 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 convex rib (4), screw body A (2) has internal thread A (5), internal thread A (5) and bolt The upper end of the screw body A (2) is...
