Abstract

The invention discloses a toothed flange locknut comprising a nut body and an annular flange integrally connected with the nut body, wherein the nut body and the flange are provided with a threaded hole along the axial direction, one side of the flange away from the nut body is provided with a coaxial countersink communicated the threaded holes, and a plurality of thread slots are formed in the nut body and the flange surrounding the threaded hole. The two ends of the through slots are respectively communicated with the threaded hole and the countersink. One end of each through slot away fromthe flange is provided with a bent portion inclining towards the threaded hole. A blocking piece is further inserted in each through slot, one end of the blocking piece protrudes out of the through groove to be fixed on a platform between the threaded holes and the countersink, the protruding portion of the blocking piece is provided with an arc portion, and the other end of the blocking piece isprovided with a tip end. One side of the flange away from the nut body is provided with anti-slip teeth. The locknut is simple in overall operation and good in locking effect.

Description

technical field [0001] The invention relates to the technical field of nuts, in particular to the technical field of a toothed flange lock nut. Background technique [0002] For the convenience of connection, the two parts connected by bolts and nuts usually make the bolt hole of one part very large, so that it will be very convenient to align the two parts. The bolt connection can be realized without the two holes being very accurate. Enlarging the bolt hole will inevitably lead to a reduction in the contact area between the ordinary nut and the connected piece, which can be avoided by using this flange nut. Flange nuts and general hexagon nuts are basically the same in size and thread specifications, but compared with hexagon nuts, it is a gasket and nut that are integrated, and there is an anti-slip tooth pattern under the gasket, which increases the size of the nut. The contact between the nut and the surface area of ​​the workpiece is stronger and stronger than the com...
