Problems solved by technology
When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the threaded hole of the nut, which may cause mechanical failure

The invention discloses a locking nut which comprises a nut body and two L-shaped rotating blocks. A threaded hole is formed in the nut body, a round corner is formed at the bottom of an I portion of each L-shaped rotating block, multiple protrusions are arrayed on the inner end face of a - portion of each L-shaped rotating block, two horizontal grooves are symmetrically formed in the nut body and communicated with the outside, vertical containing grooves communicated with the horizontal grooves are formed in the nut body, the I portion of each L-shaped rotating block is contained in the corresponding containing groove, width of each horizontal groove is larger than that of each L-shaped rotating block, and the I portions of the L-shaped rotating blocks can slide up and down in the containing grooves and can overturn downwards when upwards sliding to the highest positions. When not in use, the locking nut is similar to a nut generally used at ordinary times, small in occupied space, convenient to carry and use, capable of serving as a common nut and multipurpose.
Description
technical field [0001] The invention relates to an anti-loosening nut, in particular to an anti-loosening nut used on plates, and belongs to the technical field of mechanical fasteners. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is used to fasten and connect two mechanical parts with through holes. If the bolt is unscrewed from the nut, the two parts can be separated, so the connection is a detachable connection, and can also be widely used on plates. When the mechanical equipment is running, it will inevitably produce mechanical vibration. Long-term mechanical vibration will cause the nut to shake, lead to thread wear, and make the fastening effect worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision equipment. Machining accuracy, there may also be a phenomenon that the bolt escapes from the threaded hole of the nut, which may caus...
