Integrated self-locking nut

Abstract

The invention discloses an integrated self-locking nut, and particularly relates to the technical field of self-locking nuts, the integrated self-locking nut comprises a body, a threaded hole is formed in the body, a limiting groove is formed in the right end of the body, five clamping grooves are formed in the right part of the body at equal intervals, and two mounting rings are fixedly connected in the left end and the right end of the limiting groove. By rotating a rotary knob, when a threaded hole is in threaded fastening connection with a bolt or a screw rod, a stepped barrel is driven to rotate, so that a gear barrel rotates, the outer wall of the gear barrel is in meshing transmission with five sector gears, the sector gears rotate around a fulcrum shaft, a support rotationally extends out of the space between two mounting rings, a clamping block extends out, and the clamping block is in sliding clamping connection with a clamping groove; the anti-loosening nut has the advantages of being simple in structure, low in machining cost, convenient to operate, good in anti-loosening and anti-vibration effect, suitable for batch production and high in practicability, and rotation of the body is limited, so that when the nut is affected by external vibration and other factors, the nut cannot be separated from a bolt or rotation of a screw rod, and the nut is prevented from loosening.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of self-locking nuts, in particular to an integrated self-locking nut. Background technique [0002] The nut is the nut, which can be used to fasten and connect other parts by screwing together with the bolt or screw through the inner thread. Nuts are a kind of component that all production machinery must use. According to different materials, they are divided into several types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures. There are also three kinds of lock nuts: the first is to use tw...
