Detailed Description

The present utility model will be described in detail below with reference to the accompanying drawings and examples.

1-4, a stud nut assembly with anti-torsion structure comprises a stud 1 and a nut 2 screwed at one end of the stud 1, wherein a supporting part 3 is fixedly arranged at one end of the stud 1 far away from the nut 2, a buffer plate 4 is arranged at one end of the supporting part 3 close to the nut 2, and when the prestress of the nut 2 and the stud 1 is too high, the buffer plate 4 is slowly close to the supporting part 3 at the moment.

In the above embodiment, the stud 1 is mounted on the mounting portion of the fastener or the apparatus, the nut 2 is screwed on one end of the stud 1 so that the mounting portion of the fastener or the apparatus is established between the support portion 3 and the nut 2, the screwing nut 2 shortens the distance between the support portion 3 and the nut 2, and when the prestress of the nut 2 pressing the fastener is excessively high, the fastener presses the buffer plate 4 to slide toward the support portion 3 (the fastening force of the stud 1 is larger than the supporting force of the buffer plate 4).

In particular, the end face of the nut 2 close to the buffer plate 4 is provided with a plurality of hemispheres 5 in an array.

In the above embodiment, the arrangement of the hemispheres 5 reduces the contact surface of the nut 2 and the fastener, and reduces the friction between the nut 2 and the fastener.
