[0007] Preferably, the shrink ring is made of rubber or nylon, and a notch with a circular cross-section is provided on one side of the shrink ring, and a limiting column is built into the notch.
[0008] Preferably, the diameter of the limiting column is larger than the opening length of the notch, so that the limiting column will not fall off therefrom.
[0009] Preferably, the diameter of the limiting column is smaller than the inner diameter of the notch.
[0010] Preferably, the shrink ring is inwardly fixedly connected to the locking ring.
[0011] Preferably, the locking ring is made of stainless steel, and shrinkage openings are equidistantly arranged inside the locking ring, and there are at least four shrinkage openings.
[0012] Preferably, the flange comprises a body and anti-skid teeth, and a plurality of anti-skid teeth are provided at the bottom of the body.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model discloses an anti-skid self-locking nut for a nuclear power water gate, which tightens the screw rod by shrinking the shrink ring and the locking ring, thereby improving the self-locking ability of the nut and increasing the strength of the connection. Anti-skid teeth are arranged under the nut flange to provide higher friction force for the connection, ensuring that the nut remains stable and safe during use, thus avoiding accidents.
