▎ 摘　　要

NOVELTY - Lubricating rust-proof pin shaft, comprises a pin shaft (1), and rust-proof coating (2). The pin shaft (1) comprising a pin shaft main body (11), a pin shaft head (12), a pressing cover, a pressing cover bolt (14), a bolt hole, a grease nozzle, an oil groove, an oil passage, and an oil through-hole. The pin shaft main body is cylindrical. The pin shaft main body is located between the pin shaft head and the pressing cover. The pin shaft head is fixedly connected with the pin shaft main body. The pressing cover is movably connected with the pin shaft main body through the pressing cover bolt. The oil through-hole is set between the oil groove and the oil passage. The rust-proof coating is composed of 40-60 pts. wt. water-based epoxy resin emulsion, 15-25 pts. wt. rust inhibitor, 5-7 pts. wt. graphene powder, 3-5 pts. wt. filler, 2-4 pts. wt. auxiliary agent, and 45-55 pts. wt. de-ionized water. USE - Used as a lubricating rust-proof pin shaft. ADVANTAGE - The rust-proof pin shaft does not easily corroded and rusted and can work normally during long-term use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the lubricating rust-proof pin shaft.
