Description
Technical field
The utility model relates to a kind of novel anti-loose anti-theft nut.
Background technique
At present, traditional nut all can screw in or screw out at bolt, service time of a specified duration after, loosening easily, also can't prevent from illegally screwing out nut, if prevent from illegally screwing out nut, then need nut is welded, and the mode by welding is antitheft, effect is not remarkable, brings burden for the field operation personnel, for providing convenience to operation, the novel anti-loose anti-theft nut of special production, quick and easy for installation.
The model utility content
The utility model provides a kind of novel anti-loose anti-theft nut in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of novel anti-loose anti-theft nut, it is characterized in that: comprise body and end cap, described body is provided with bolt hole, described bolt hole inwall is provided with skewed slot, be provided with steel ball and spring in the described skewed slot, described end cap comprises insertion part and end face, and inserting bolt hole, described insertion part and sealing skewed slot do not drop steel ball and spring.
During installation, see through firm workpiece, no end cap one end of the utility model nut body is screwed in bolt, in the screw-in process, bolt ejects the end cap of nut body opposite side gradually, and steel ball is contacted with bolt, when nut body reverses, spring promotes steel ball, and steel ball is just wedged in the skewed slot, reaches the purpose of self-locking non-return.
The utility model advantage compared with prior art is: the utility model is simple in structure, easy for installation, locking, burglar-proof mechanism is hidden, fastening back is locking, anti-theft feature is reliable, and have the function of tightening up, and nut mechanical property and guarantee that load can both satisfy the GB/T3098.2-2000 standard-required.
