Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut to be used for fastening and connecting two parts with through holes, and the connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to a detachable connection, and when the bolt is fastened, the engaged contact surfaces mutually rub and slide under the condition of high stress. This usually causes some damage to the nut end face, the surface of the object to be clamped, and the thread contact surface, and when the bolt is fastened again, the damage becomes worse, which usually results in an increase of the friction coefficient, because the increase of the friction coefficient reduces the bolt axial force for a certain moment, so the thread groove needs to be lubricated;

for example, the application publication number is CN208221285U, a front axle steering knuckle bolt with a lubricating function comprises a stud and a bolt head arranged at the upper end of the stud, the outer wall of the stud is provided with threads, and an oil storage space is arranged in the stud; a partition pipe is arranged in the oil storage space; the oil storage space is divided into an outer oil cavity and an inner oil cavity by the partition pipe; one side of the upper end of the outer oil cavity is connected with an oil outlet communicated with the outer oil cavity, and an orifice at one end of the oil outlet is positioned on the outer wall of the stud; the screw head is provided with a through hole communicated with the inner oil cavity; a piston matched with the inner oil cavity is arranged in the inner oil cavity; a push rod is connected above the piston; one end of the push rod penetrates through the through hole and is provided with a push head, and the top end of the push head is provided with a rotating groove;

the front axle knuckle bolt with the lubricating function does not need to be taken out from the front axle knuckle by the bolt, can lubricate in the screwed state, not only can the bolt be effectively prevented from rusting, but also the workload caused by lubrication can be reduced to the greatest extent, but the lubricating mode cannot completely cover the thread groove, so that the gap between the threads cannot be easily filled with lubricating oil, and when the lubricating is needed, the lubricating oil cannot effectively lubricate.
