Abstract:
1. A self-lubricating mechanism of slide member, comprising: a slide assembly including a linear guide section and a slider slidably mounted on the guide section and linearly reciprocally movable along the guide section between a first position and a second position, the slide assembly further including at least one rolling section held between the slider and the guide section and received in a space defined between the slider and the guide section; and a lubricating section having a main body fixedly disposed at one end of the slider, the main body having a first side and a second side, the first side of the main body being connected with the end of the slider, an oil reservoir being formed in the main body for containing a lubricating oil therein, the self-lubricating mechanism being characterized in that the lubricating section further has at least one passage formed in the main body in communication with the oil reservoir, the at least one passage having an opening on the first side of the main body in communication with the space in which the at least one rolling section is received; a push body slidably disposed on the main body, a first end of the push body extending into the oil reservoir, a second end of the push body outwardly extending from the second side of the main body; and a stopper body fixedly disposed in a position adjacent to the first position and distal from the second position, one side of the stopper body correspondingly facing the second end of the push body, whereby when the slider is displaced to the first position, the second end of the push body abuts against the side of the stopper body, when lubrication is required, the slider being further moved in a direction away from the second position through a predetermined distance, whereby the push body is stopped by the stopper body and slides relative to the main body, the push body then driving the lubricating oil contained in the oil reservoir out of the opening of the at least one passage to fill the lubricating oil into the space in which the rolling section is received, whereby the at least one rolling section and faces in contact therewith are lubricated with the lubricating oil.
