The anti-loose bolt and nut set comprises a bolt and a nut, wherein the bolt (1) is provided with a locking groove (11); the right end surface of the nut (2) is a spigot (8) provided with a turnup edge (9); the spigot is internally provided with a locking ring (5) which can rotate freely; the inner wall of the left end surface of the locking ring is provided with a circle of ratchets (10), while the inner wall of the right end surface thereof is provided with a boss (7) adaptive to the locking groove (11); the outer wall of the nut (1) is provided with a marble hole; the marble hole is internally provided with a spring (6) and a marble (3); and the cylindrical surface of the marble (3) is provided with pawls (4) adaptive to the ratchets (10). The anti-loose bolt and nut set not only has good anti-loose effect but also can be used repeatedly, and is an ideal anti-loose fastening piece.
Description
Technical field:The utility model relates to a kind of fastening piece, relates in particular to a kind of bolt, nut external member of becoming flexible of can preventing.
Background technique:At present, loosening in order to prevent that nut from producing, adopt the mode of fasteners such as increasing elastic washer, toothed washer or shell fragment to come locking nut usually; But in the more serious occasion of some vibrations, said method is effective locking nut still, machinery equipment usually because of nut loosening, come off and cause damage, even also can cause casualty accident.
Summary of the invention:At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of simple in structure, easy accessibility, chek bolt, nut external member that anti-loosing effect is good.
To achieve these goals, the utility model by the following technical solutions: it comprises screw bolt and nut; Bolt is provided with locking slot, and the right side of nut is the seam that is provided with flange, is provided with locking ring free to rotate in this seam, and the inwall that the inwall of this locking ring left side is provided with a circle ratchet, this locking ring right side is provided with the boss suitable with locking slot; The outer wall of nut is provided with the pellet shot from a slingshot hole, is provided with spring and pellet shot from a slingshot in this pellet shot from a slingshot hole, and the cylndrical surface of pellet shot from a slingshot is provided with the ratchet suitable with ratchet.
Compared with the prior art, the utility model is owing to increased locking slot on plain bolt, locking ring and spring courage locking mechanism on plain nut, have been increased, therefore not only effectively overcome the defective of traditional locking fastener locking effect difference, but also had easy accessibility, advantage such as reusable.
