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...

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides an integrated self-locking nut. By rotating the knob, when the threaded hole is tightly connected with the bolt or the screw, the stepped cylinder can be driven to rotate, so that the gear cylinder can rotate, and the outer wall of the gear cylinder and the five Two sector gears mesh and drive, so that the sector gear rotates around the support shaft, so that the bracket rotates and protrudes between the two installation rings, so that the clamp block protrudes, and the clamp block and the clamp groove are slidingly engaged to limit the rotation of the body, so that the nut is in the When affected by factors such as external vibration, there will be no bolt or screw rotation, which prevents the nut from loosening. It has strong self-locking property, simple structure, low processing cost, convenient operation, good anti-loosening and anti-vibration effects, and is suitable for batch production. Production, by slotting inside the body and setting the transmission mechanism, the size of the nut itself does not change much, and the self-locking component and the nut itself are integrated, which is convenient for workers to operate, which not only ensures the stability of the nut, but also improves the The efficiency of mechanical processing increases the mechanical benefits of people's processing, ensures the safety of the connection between bolts and nuts, and has strong practicability. However, the self-locking properties of the two nuts are poor, and the nuts will loosen at the same time, and the structure is very complicated, the processing cost is high, the anti-loosening effect is poor, and it is not suitable for mass production. The existing anti-loosening methods need to rely on one or more An external tool, which greatly increases the size of the nut itself, makes the nut heavy and complex in structure, increases the operating time in the use of the nut, prolongs the machining cycle, reduces the processing output per unit time, and has low practicability. question
