Hexagon nut

[0015] The present invention will be explained below with reference to the drawings.

[0016] As attached figure 1 , 2 The illustrated hexagonal nut according to the present invention includes a nut body 1 in which an oil groove 2 is provided; the oil groove 2 is annular; the oil groove 2 is filled with solid lubricating oil 3; The nut body 1 is also provided with an oil hole 4 and an oil hole 5; the oil hole 4 communicates with the outside; the oil hole 4 is provided with a plug 6; the oil hole 4 and the threaded hole of the nut body 7 is connected; the oil injection hole 4 and the oil outlet 5 are located on the same straight line; the nut body 1 is provided with a photosensitive resistor 8 and a power supply 9; the photosensitive resistor 8 is provided with a light shield 10; the nut body 1 There is a groove 11 matching the photoresistor 8 on the side surface; the photoresistor 8 is arranged in the groove 11; the side surface is also symmetrically provided with two magnets 12; the shading plate 10 passes through the magnet 12 is adsorbed on the side; the oil tank 2 is provided with a heater 13; the sensitive resistor 8, the power supply 9 and the heater 13 form a closed loop.

[0017] When the joint between the nut body 1 and the bolt or screw is rusted, the nut body 1 needs to be removed from the bolt or screw during mechanical equipment maintenance. The current of the closed circuit composed of resistor 8, heater 13, and power source 9 increases, and the heater 13 reaches the starting voltage to start. The solid lubricating oil 3 in the oil tank 2 melts into a liquid state, flows out from the oil outlet 5 and flows to the threaded hole In 7, it plays a role of lubrication. At this time, the nut body 1 can be easily removed from the bolt or screw, which improves maintenance efficiency, reduces the downtime of mechanical equipment, and increases production efficiency. After removing, put on the shading plate 10, due to the action of the magnet 12, the shading plate 10 is adsorbed on the side of the nut body 1, remove the plug 6, inject the solid lubricating oil 3 into the oil groove 2 through the grease gun, and plug the plug. It can be recycled, which avoids the nut body 1 being scrapped due to rusty threads, and reduces the processing cost.

[0018] The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those familiar with the technology to understand the content of the present invention and implement it, and cannot limit the scope of protection of the present invention. All equivalent changes or modifications made by the substance shall be covered by the protection scope of the present invention.
