Abstract

The invention relates to the technical field of fasteners, in particular to a fastener with an anti-loosening function. The fastener comprises a bolt head, wherein the bottom end of the bolt head is connected with a threaded section; the upper end of the threaded section is connected with a convex ring; the threaded section is connected with a first nut; the threaded section is connected with a second nut; the bottom end of the first nut is connected with a plurality of first connecting rods; one end of each first connecting rod is connected with the second nut; the bottom end of the threadedsection is provided with a hollow sleeve in a sleeving manner; the bottom end of the outer side of the hollow sleeve is connected with a hexagonal bulge; the interior of the hollow sleeve is connectedwith a threaded rod; a threaded hole is formed in the bottom end of the threaded section; and the upper end of the hollow sleeve is connected with a supporting frame. According to the fastener, the hexagonal bulge drives the hollow sleeve to rotate, the hollow sleeve drives the threaded rod to rotate, the threaded rod is connected with the threaded hole, the hollow sleeve rotates upwards to drivethe supporting frame to move, the upper end of the supporting frame is in contact with the second nut, when the first nut is loosened, the second nut prevents the first nut from being loosened through the first connecting rods, and the anti-loosening effect is good.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a fastener with an anti-loosening function. Background technique [0002] Fasteners are mechanical parts used for fastening connections. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, and hydraulics. They are used in various machinery, equipment, vehicles, ships, etc. Various fasteners can be seen on items such as railways, bridges, buildings, structures, tools, instruments, chemicals, and instruments. They are the most widely used mechanical basic parts. The fasteners are characterized by varieties and specifications. There are many, and the performance uses are different. [0003] When existing fasteners are locked by nuts, loosening between the bolts and nuts is likely to occur when subjected to external vibrations, resulting in poor fastening effect of the fasteners.
