Lock nut

Abstract

The invention discloses a lock nut comprising a nut body fixed on a screw. Two elastic fastening blocks are fixed on the top surface of the nut body and shaped in a hook. A linear end of each fastening block is rotationally fixed on the nut body through a small shaft, a projection block matched with a thread of the screw is arranged in an annular end of each fastening block, and the fastening blocks are fastened on the screw and clamp the nut through the projection block in the annular ends therein. Openings of the fastening blocks are oppositely fixed on the nut body. The lock nut can be fastened through the fastening blocks and prevented from loosening and is simple in structure and low in cost, industrial production efficiency can be effectively improved, and faults and safety potential hazards caused by loosening of the nut are avoided.

Description

technical field [0001] The invention relates to a mechanical fastener, in particular to a mechanical nut, which belongs to the technical field of mechanical fasteners. Background technique [0002] At present, all industrial production uses mechanical automation to improve industrial production efficiency and save a lot of production costs. In the mechanized production line, there are many fasteners such as bolts and screws. Since these fasteners are fastened with threads, they will loosen with the vibration of the machine during use. If they are not tightened in time, the machine will appear Faults, serious accidents will occur. For this reason, many machinery suppliers use self-locking nuts to fasten the machine when fastening them. However, since the price of self-locking nuts is relatively expensive, adding a few more will increase the cost of the machinery. position, secured with self-locking nuts, while most positions are secured with plain nuts. Moreover, during in...

For this reason, many machinery suppliers use self-locking nuts to fasten the machine when fastening them. However, since the price of self-locking nuts is relatively expensive, adding a few more will increase the cost of the machinery. positions with self-locking nuts and most positions with plain nuts

Moreover, during industrial production, the mechanical production line will often be maintained, which will cause the loss of self-locking nuts. It is necessary to purchase self-locking nuts of the same type, which increases the cost of industrial manufacturers, delays the production cycle, and affects industrial production.
