Locking nut

Abstract

The invention discloses a locking nut, comprising a hexagon nut body, an annular boss, a nylon ring, a flange gasket, anti-loosening elastic pieces and adjusting screws, wherein the upper end surfaceof the hexagon nut body is provided with the annular boss, the annular boss is provided with a mounting ring groove, the nylon ring is embedded in the mounting ring groove, the center line of the hexagon nut body is provided with a central threaded hole, the lower end face of the hexagon nut body is connected with the flange gasket, the lower end face of the flange gasket is provided with a plurality of containing grooves, the anti-loosening elastic pieces are arranged in the containing grooves, and the adjusting screws are installed on the side wall of the hexagon nut body. The adjusting screws cooperate with the anti-loosening elastic pieces, the multiple adjustable anti-loosening elastic pieces are arranged under the flange gasket, so that the locking reliability is ensured, and the locking nut is especially suitable for the uneven fastening situation of the fastening end face, and the resilience force to the bolt is generated by extruding deformation of the threads of the bolt to the nylon ring, so that the problems of loosening and slipping off under the condition of vibration can be effectively solved.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to a lock nut. 【Background technique】 [0002] Lock nuts are widely used in the workplace where different workpieces are connected to each other. The nylon self-locking nuts on the existing market usually include a nut body, an annular boss and a flange. The center of the nut body is provided with an internal thread hole, and the annular boss The platform and the flange are respectively arranged at the upper and lower ends of the nut body and are integrally formed with it. The inner threaded hole runs through the two ends of the flange, and the inner wall of the annular boss is provided with a nylon ring. However, when tightening the nylon self-locking nut, because the nylon ring in the annular boss is not easy to be compressed, and its surface is smooth, it is easy to spin, which will cause the bolts that match it to be difficult to enter the inner hole of the nylon ring, there...

AI Technical Summary

Problems solved by technology

However, when tightening the nylon self-locking nut, because the nylon ring in the annular boss is not easy to be compressed, and its surface is smooth, it is easy to spin, which will cause the bolts that match it to be difficult to enter the inner hole of the nylon ring, thereby Due to the difficulty in tightening and assembling nylon self-locking nuts, the nuts installed outdoors are more likely to be subject to shock and vibration, and are prone to loosening and falling off. Therefore, a locking nut is proposed
