Anti-loosening combined connecting piece

Abstract

The invention discloses an anti-loosening combined connecting piece. The anti-loosening combined connecting piece is provided with a bolt and a nut which are matched with each other, the upper end face of the nut is provided with a plurality of clamping grooves, the clamping grooves extend in the radial direction of the nut and are evenly distributed in the circumferential direction of the nut, the anti-loosening combined connecting piece is further provided with a locking nut, the lower end face of the locking nut is provided with one or more sets of convex teeth, and the convex teeth are matched with the clamping grooves on the nut. When the anti-loosening connecting piece is used, firstly, two connected pieces are connected through the bolt and the nut, then the locking nut is combined with the bolt, the locking nut is gradually tightened, the convex teeth on the locking nut enter the clamping grooves in the nut, and the nut can be prevented from loosening through matching of the convex teeth and the clamping grooves.

Description

technical field [0001] The invention relates to a coupling, in particular to a loosening-proof combined coupling. Background technique [0002] At present, a commonly used joint is composed of bolts and nuts that cooperate with each other. This joint can reliably connect two parts or components tightly, but the disadvantage is that when the connected parts or parts are working When there is more frequent vibration in the state, there will be a slight relative rotation between the bolt and the nut, and the small relative rotation will gradually accumulate, which will lead to loosening of the interconnected parts or parts. If it is not handled in time, it will affect the working performance and seriously will lead to accidents. Contents of the invention [0003] The object of the present invention is to provide an anti-loosening combined coupling, which can reliably connect the connected parts and avoid loosening between the connected parts. [0004] In order to achieve th...
