Problems solved by technology

[0002] Threaded connectors are widely used in almost all mechanical products due to their convenient disassembly and assembly, various forms and flexible use, and threaded connections through bolt threads and hexagon nuts are also very common; however, existing bolt threads and Due to the rigidity and single-helical surface fit of the hex nut connection, there is uneven force on the thread, which leads to damage to the bolt thread and the hex nut. Especially in the mechanical thread connection with vibration, it is necessary to install anti-vibration and anti-skid accessories. When there is a special need for threaded connections such as safety, the manufacturing requirements for cylindrical external threads and hexagonal nuts are particularly high, so manufacturing is difficult and costly

Abstract

The invention discloses a sheet metal hexagon nut, which comprises an inner hexagon nut and an outer hexagon nut. The inner hexagon nut is embedded in the outer hexagon nut. One side of the inner hexagon nut is provided with an inner sheet metal substrate, and the inner sheet metal substrate One side is provided with an inner sheet metal thread, the middle part of the inner sheet metal thread is provided with a first opening, one side of the outer hex nut is provided with an outer sheet metal substrate, and one side of the outer sheet metal substrate is provided with an outer sheet metal thread , the middle part of the outer sheet metal thread is provided with a second opening; when the thread helix male surface of the inner hexagon nut and the outer hexagon nut respectively fits with the male surface and the female surface of the cylindrical external thread, it will form elasticity to comply with the cylindrical external thread Precision pairing forms a stable, elastic, precise and safe anti-loosening fastening connection; its structure and manufacturing process are simple, energy-saving and environmentally friendly, light in weight and low in cost.

Description

technical field [0001] The invention relates to the technical field of screw connection, in particular to a sheet metal hex nut. Background technique [0002] Threaded connectors are widely used in almost all mechanical products due to their convenient disassembly and assembly, various forms and flexible use, and threaded connections through bolt threads and hexagon nuts are also very common; however, existing bolt threads and Due to the rigidity and single-helical surface fit of the hex nut connection, there is uneven force on the thread, which leads to damage to the bolt thread and the hex nut. Especially in the mechanical thread connection with vibration, it is necessary to install anti-vibration and anti-skid accessories. When there is a special need for threaded connections such as safety, the manufacturing requirements for cylindrical external threads and hex nuts are particularly high, so manufacturing is difficult and costly. [0003] Therefore, it is necessary to i...
