Sealing device for filling anaerobic lubricating oil

Abstract

The utility model relates to the technical field of lubricating oil sealing, and discloses a sealing device for filling anaerobic lubricating oil, which comprises a main body structure and a fixing structure, the fixing structure is arranged in the main body structure, the main body structure comprises a lubricating oil barrel, and a sealing cover is clamped at the top of the lubricating oil barrel. A sealing plug is fixedly connected to the bottom of the sealing cover, a sealing air bag is arranged at the lower end of the outer wall of the sealing plug, an air inflation pipe is fixedly connected to the air inlet end of the sealing air bag, the sealing cover and the sealing plug are installed at the top of the lubricating oil barrel, and the sealing cover and the lubricating oil barrel are tightly attached by arranging a graphite gasket and a sealing ring; according to the lubricating oil barrel sealing device, the connecting position of a lubricating oil barrel is sealed, the leakage phenomenon of the lubricating oil barrel is avoided, the sealing air bag is inflated through the inflation pipe by pressing the inflation switch and starting the inflation device, the gap between the lubricating oil barrel and the sealing plug is filled through the bulged sealing air bag, and therefore the good sealing effect is achieved through double sealing.
