Abstract

The invention discloses a bolt with an oil discharge function. The bolt comprises a bolt body formed by connection of a bolt head and a screw. An oil storage slot is formed in the screw and is filled with lubricating oil. Oil outlet holes communicated with the oil storage slot are formed in the screw. Each oil outlet hole comprises an oil inlet flow pass and two oil outlet flow passes in the shape of a labyrinth. The oil inlet flow passes are communicated with the oil outlet flow passes. A piston is arranged at an opening of the oil storage slot. A push rod is connected to the outer end of the piston and penetrates the bolt head to be connected with the piston. A push plate is arranged at the outer end of the push rod. The bolt with the oil discharge function has the advantages that the oil storage slot is filled with the lubricating oil, the piston squeezes internal space of the oil storage slot in case of rusting, and the lubricating oil leaks out from the oil outlet holes to lubricate a joint part of the screw and a mechanical component, so that the bolt is simple in structure, convenient to use and high in oil discharge and lubrication efficiency; since each oil outlet hole comprises the two oil outlet flow passes in the shape of the labyrinth, and the lubricating oil is stored in the oil storage slot and is not leaked, so that lubrication effect during use of the lubricating oil is guaranteed, and use cost is low.
