Problems solved by technology

Hex nuts are usually exposed to the atmosphere. Due to the corrosion of corrosive gases and liquids or the corrosion of dust and water vapor, rust often occurs at the junction of hex nuts and bolts or screws. During maintenance of mechanical equipment, hex nuts are extremely Difficult to remove from the bolt or screw, which affects the maintenance efficiency, increases the downtime of mechanical equipment and reduces the production efficiency

Abstract

The invention discloses a hexagon nut. The hexagon nut comprises a nut body, wherein an oil groove is arranged in the nut body and is filled with solid lubricating oil; an oil filling hole and an oil discharging hole are also arranged in the nut body; the oil filling hole is communicated with the outside; a plug is arranged in the oil filling hole; the oil discharging hole is communicated with a threaded hole of the nut body; a light-sensitive resistor and a power supply are arranged outside the nut body; a heater is arranged in the oil groove; the light-sensitive resistor, the power supply and the heater form a closed loop; and a light shielding plate is arranged outside the light-sensitive resistor. The hexagon nut can be easily dismounted from a bolt or a screw when machinery equipment is repaired after the joint of the hexagon nut and the bolt or the screw is rusted, so that the repair efficiency is improved, the shutdown time of the machinery equipment is shortened, and the production efficiency is enhanced.

Description

technical field [0001] The invention relates to a hexagonal nut, in particular to a hexagonal nut which can be easily removed even when rusted, and belongs to the technical field of threaded joint elements. Background technique [0002] Hex nuts are commonly known as nuts, which are parts that are screwed together with bolts or screws for fastening, and are widely used in mechanical equipment. Hex nuts are usually exposed to the atmosphere. Due to the corrosion of corrosive gases and liquids or the corrosion of dust and water vapor, rust often occurs at the junction of hex nuts and bolts or screws. During maintenance of mechanical equipment, hex nuts are extremely It is not easy to disassemble from the bolt or screw rod, which affects the maintenance efficiency, increases the downtime of mechanical equipment, and reduces the production efficiency. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is t...
