Examples

As shown in fig. 1 and 2, the elastic locknut with the micro claw disc comprises a nut body 1 and a locking boss 2, wherein the nut body 1 and the locking boss 2 are coaxially arranged, and the locking boss 2 is fixedly arranged on the end face of one axial end of the nut body 1; the locking boss 2 is annularly arranged, a group of first openings 21 is arranged in the axis direction of the locking boss 2, the group of first openings 21 are arranged in the radial direction of the locking boss 2, the group of first openings 21 are arranged in an annular array mode by taking the center of the locking boss 2 as the center of a circle, the group of first openings 21 divide the locking boss 2 into a group of fan-shaped claw discs 22, and the group of fan-shaped claw discs 22 are arranged in an annular array mode by taking the center of the locking boss 2 as the center of a circle. And the nut body 1 is a hexagonal nut.

In addition, the outer wall of the locking boss 2 close to one end of the nut body 1 is provided with a U-shaped groove 23.

And thirdly, the inner wall of the nut body 1 is provided with a first internal thread 11. And a second internal thread is arranged on the inner wall of the locking boss 2, and the pitch of the second internal thread is the same as that of the first internal thread 11.

In addition, the outer wall of the locking boss 2 is arranged in a conical shape. The inner wall of the locking boss 2 is in a conical shape, and the fan-shaped claw disc 22 is in a contraction shape towards the direction far away from the nut body 1. And a chamfer angle I24 is arranged on the inner wall of one end, far away from the nut body 1, of the locking boss 2.
