[0017] like Figure 1-5 As shown, the self-seeping oil-proof plug involved in the utility model includes a plug body 1, an oil-seeping sponge 2 and a plug 3. A plug through hole 5 is provided inside the plug body 1. The plug body 1 is provided with a plug front cylinder 6, a plug middle cylinder 7 and a plug rear cylinder 8 with outer diameters increasing from front to back. The plug front cylinder 6 is provided with a compressible outer extrusion convex edge 9 at intervals near the plug middle cylinder 7. The outer diameter of the outer extrusion convex edge 9 is greater than the outer diameter of the plug middle cylinder 7. The plug front cylinder 6 is provided with a plug reserved cavity 10 for inserting the oil-seeping sponge 2 inside the outer extrusion convex edge 9. The plug through hole 5 is provided at the outer extrusion convex edge 9. An inner extrusion convex edge 11 is provided at intervals on the inner wall of the pressed convex edge 9, and an oil seepage gap 12 is provided on the inner extrusion convex edge 11, which is communicated with the waterproof plug reserved cavity 10, and a plug insertion hole 13 is provided on the upper end face of the outer extrusion convex edge 9, which is communicated with the waterproof plug reserved cavity 10 and is used for installing the plug 3. The waterproof plug body 1 and the oil seepage sponge 2 are injection molded as one piece, which reduces the assembly process and improves product consistency and reliability. By integrating the oil seepage sponge 2 in the waterproof plug body 1, sealing is achieved while slowly releasing lubricating oil, extending the life of the equipment and reducing component wear. Lubricating oil can be repeatedly added through the plug 3, and frequent use has high product utilization rate.
