Abstract
The invention discloses an anti-loosening nut. The anti-loosening nut comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is sleeved with the outer sleeve. An internal thread is arranged on the inner surface of the inner sleeve. A plurality of through holes are formed in the wall of the inner sleeve. A plurality of guide holes are formed in a lower check ring. Insertion posts are inserted in the guide holes respectively. The lower ends of the insertion posts are connected with a fixing ring located below the lower check ring. A cavity formed among the inner sleeve, the outer sleeve, an upper check ring and the lower check ring is filled with steel balls. Part of the outer walls of the steel balls penetrate through the through holes and are compressed on the outer surface of a bolt or a stud. The inner wall of the outer sleeve is provided with a pushing face. A compression nut is fixedly mounted on the upper surface of the upper check ring. A gap is formed between the fixing ring and the bolt or the stud, and a gap is also formed between the lower check ring and the bolt or the stud. While the anti-loosening nut is screwed, the insertion posts are inserted more and more deeply, the space occupied by the insertion posts becomes bigger and bigger, the steel balls are compressed on the outer surface of the bolt or the stud more and more tightly through the through holes, and therefore the anti-loosening nut is prevented from loosening.
