The invention provides an anti-loosening bolt and an anti-loosening hanging ring device, and relates to the technical field of hanging rings. The anti-loosening bolt comprises a bolt body, wherein a positioning shoulder is arranged at one end of the bolt body, the diameter of the positioning shoulder is larger than that of the bolt body, a U-shaped groove is formed in the other end of the bolt body, the U-shaped groove penetrates through the bolt body from the diameter direction of the bolt body, and a rotatable anti-loosening bolt is arranged in the U-shaped groove. After the anti-loosening bolt is inserted into the hanging ring body, the anti-loosening bolt is rotated, so that the anti-loosening bolt can stretch across a through hole of the hanging ring body, and the anti-loosening boltis prevented from falling off from the through hole of the hanging ring body; and the anti-loosening bolt is simple in structure and convenient to use, and the reliability of the device is improved.
