Abstract
The utility model provides a ball nut which comprises an upper nut (1), a lower nut (2) and balls (3). The shape of the ball nut is a rounded square, screw threads are arranged in round holes, and the cylindrical balls (3) are embedded between U-shaped grooves at the bottom of the upper nut (1) and U-shaped grooves at the top of the lower nut (2). When the lower nut (2) is fastened on a screw, the upper nut (1) performs secondary fastening to achieve the effect of non-looseness. Furthermore, due to the cylindrical balls (3) arranged between the two nuts, the non-looseness effect can be achieved even though the nuts are loosened. The design of the ball nut has certain positive meaning. Therefore, the ball nut is widely used in families and other places in the society gradually.
