Embodiment Construction

[0014] see Figure 1 to Figure 9 , first illustrate the arrangement of a plurality of strip-shaped convex ribs 4, assuming that the number of clips 13 is N, N is an even number, the number of the same groove 9 is also N, the width of the groove 9 is A, and a plurality of clips 13 are formed The radius of the imaginary circle 16 at the center point of the outer surface of the conical ring is R, and the arc length of the center point of each clip 13 is C, then C=2∏R / N-A, and it is assumed that the extrusion part 3 of the nut A1 M convex ribs 4 are arranged on the inner surface of the conical ring corresponding to the arc length C of the clip 13, and the virtual circle radius of the center point of the inner surface of the conical ring of the extruded part 3 of the nut A1 is R'. When nut A1 and nut B6 are processed, R=R', the distance between the central axes of adjacent convex ribs 4 is B, then B=C / M, and the projection circle of the inner surface of the conical ring of the extr...

Abstract

The invention discloses an interlocking check nut. The interlocking check nut is mainly used in the machinery field. The interlocking check nut has the interlocking function. The tightened nut is notreleased from a bolt, and manufacturing and use are convenient. The interlocking check nut is composed of a nut body A and a nut body B. According to the working principle and mounting process, the clamping portion of the nut body B is upwards tightened, the lower end of the nut body B compresses a workpiece, the extrusion portion of the nut body A is downwards screwed on the bolt and jacks the clamping portion of the nut body B tightly, a plurality of convex ribs of the extrusion portion of the nut body A extrude a plurality of clamping pieces of the nut body B, inner threads B of the multiple clamping pieces extrude outer threads of the bolt, the outer threads of the bolt are tightly hooped, the anti-looseness purpose is achieved, and at least one convex rib is clamped into a groove of the nut body B in the process, so that interlocking is achieved; and under the function of vibration loads, the nut body A loosens firstly, the convex ribs clamped into the groove of the nut body B also prevent the nut body A from loosening, and at the same time, the multiple convex ribs tightly clamp the outer threads of the bolt, the anti-looseness purpose 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 outer thread of the screw body A (2)...
