Abstract
The invention provides an antitheft nut assembly comprising a nut body, a ring, a nut shell, a cylinder outer shell, and a cylinder inner shell. The cylinder inner shell and the cylinder outer shell are positioned inside the nut shell. If a butt block of the cylinder inner shell is not abutted to positioning steel balls, the positioning steel balls are no longer embedded in positioning grooves of the nut shell, the nut shell cannot drive the nut body to rotate, the nut shell rotates idly, and the nut assembly cannot be removed in the non-unlocking state. In order to remove the nut assembly, the cylinder inner shell is rotated with a key to allow locking steel balls of the cylinder outer shell to fall into arc grooves of the cylinder inner shell, the locking steel balls separate from locking grooves of the nut shell, a spring in the nut body pops an ejector pin outside, the cylinder outer shell moves out with the cylinder inner shell, the butt block pushes the positioning steel balls to move out and embed the balls into the positioning grooves, the nut shell can drive the nut body to rotate, and the nut body can be removed from a bolt or screw. Optimal antitheft effect is achieved.
