Abstract
The utility model provides an anti-loosening connecting fastener, comprising a bolt and a nut; the anti-loosening connecting fastener is characterized in that a screw rod of the bolt is provided with a first groove extending axially; one end of the first groove extends out of the end surface of the screw rod; the threaded hole wall of the nut is provided with a second groove extending axially; two ends of the second groove respectively extend out of two end surfaces of the nut; the first groove and the second groove are aligned to form an oblong hole, in which a location-limiting pin is clamped. When the nut is locked in place, the location-limiting pin is clamped in the oblong hole and can prevent the circumferential rotation generated between the nut and the threaded rod of the bolt, so that the loosening and disconnecting of the nut from the bolt is prevented and the connecting and fastening reliability is improved.
Description
Technical field
The utility model relates to a kind of connection fastening piece, relates in particular to a kind of anti-loosening connection fastening piece.
Background technique
Usually adopt between the mechanical part and connect the mutual fixed connection of fastening piece realization; Common connection fastening piece comprises the screw bolt and nut structure at present; This existing connection fastening piece is widely used; But also have following problem: tend to produce vibrations between the connected mechanical part, nut produces circumferentially rotation under the effect of shaking force, at this moment nut loose or dislocation from the bolt easily.
The model utility content
The technical problem that the utility model solves is: a kind of anti-loosening connection fastening piece simple in structure, easy to use is provided.
The technological scheme of the utility model is: a kind of anti-loosening connection fastening piece; Comprise screw bolt and nut; It is characterized in that the screw rod of said bolt is provided with axially extended first groove, an end of this first groove extends the end face of said screw rod; The screw thread hole wall of said nut is provided with axially extended second groove; The both ends of the surface of said nut are extended at the two ends of this second groove respectively, and the common oblong aperture that forms of said first groove and said second notch aligns has snapped in a position limit pin in this oblong aperture.
The screw rod of said bolt is provided with two first grooves, and the screw thread hole wall of said nut is provided with two second grooves, and is corresponding one by one between said two first grooves and said two second grooves.
The beneficial effect of the utility model is: after nut check puts in place; Position limit pin is snapped in the oblong aperture; Position limit pin can prevent to produce circumferential rotation between the threaded stem of nut and bolt, thereby prevents nut loose or dislocation from the bolt, has improved to connect fastening reliability.
