Zusammenfassung:	The utility model provides a lock nut not easy to loosen, which relates to the field of threaded fasteners and comprises a lock main nut and a nut with an inner cone, a lock main nut threaded hole is processed in the lock main nut, a plurality of outer cones are arranged on the upper portion of the lock main nut, and the radius of each outer cone is gradually reduced from bottom to top. A nut threaded hole with the inner cone is machined in the nut with the inner cone, the inner cone is arranged on the lower portion of the nut with the inner cone, and the radius of a groove part of the inner cone is gradually reduced from bottom to top to be matched with the outer cone. According to the anti-loosening nut not prone to loosening, the inner cone side face of the nut with the inner cone extrudes the side face of the outer cone part of the main anti-loosening nut through the tightening effect of the nut with the inner cone on a matched bolt, inner threads of the outer cone make full contact with outer threads of
