Mortise and tenon structure anti-loosening nut assembly with tenon screw

Abstract

The invention discloses a mortise and tenon structure anti-loosening nut assembly with a tenon screw. The mortise and tenon structure anti-loosening nut assembly is reasonable, rigorous and reliable in structure. The nut can be effectively prevented from loosening, and the problem of loosening of the bolt and the nut is directly and fundamentally solved through the nut anti-loosening structure. The assembly comprises a fastening nut, and two semicircular mortises, namely a semicircular mortise I and a semicircular mortise II, are formed in the lower part of the fastening nut; the upper portion of the double-mortise element is provided with two semicircular mortises which are the semicircular mortise III and the semicircular mortise IV respectively, and the plane, making contact with the double-face anti-skid gasket, of the lower portion of the double-mortise element is provided with concave-convex patterns with the anti-skid function. The assembly also comprises atenon screw, the head of the tenon screw is a cross groove, a threaded rod with threads is matched with a screw mortise formed by the semicircular mortise of the fastening nut and the semicircular mortise of the double-mortise element, and after the fastening nut is fastened, the tenon screw is screwed into the mortise to form a mortise and tenon structure; the upper surface and the lower surface of the double-face anti-skid gasket are provided with concave-convex patterns with an anti-skid function.

Description

technical field [0001] The invention relates to a nut assembly, in particular to an anti-loosening nut assembly under vibration conditions. Background technique [0002] Electrical equipment such as main transformers, high (low) voltage reactors, station transformers, generators, motors and other electrical equipment installed and used in substations (power plants) will vibrate during operation; High-altitude fittings swing under natural conditions, such as the swing caused by wind blowing. Wind blowing above a certain level will cause the transmission line and related high-altitude connecting fittings to swing back and forth, causing the bolts and nuts at the fastening place to loosen; other technical fields such as rails In transportation, bolts and nuts are important railway accessories. The bolts and nuts installed on the railway track directly bear the severe vibration generated by rolling stock and its load. [0003] According to the survey, in order to solve the loos...
