The invention relates to the field of glue pipe glue sealing, and discloses a columnar sealing cover. The columnar sealing cover comprises a cover body which is in a column shape; the inner side of the cover body is provided wiht an inner thread for being connected with a pipe opening; the center of the bottom of the cover body is provided with an opening sealing column body used for plugging thepipe opening, and the opening sealing column body is sleeved with a sealing gasket; the outer side of the cover body is provided with anti-slide ribs, and the anti-slide ribs are perpendicular to thebottom of the cover body and are uniformly distributed on the outer side of the cover body; manufacturing is convenient, the structure is simple, the attactive and practical effects are achieved, andthe anti-slide effect is good; the anti-slide ribs are perpendicular to the bottom of the cover body, and thus, the cover body and the glue pipe can be connected or disconnected through screwing conveniently; when the cover body seals the pipe opening through the inner thread, meanwhile, the pipe opening is plugged by the opening sealing column body, and the opening sealing column body is inserteditno the pipe opeing in a sealed mode; the cover body and the opening sealing column body seal the pipe opening from the outer side and the inner side correspondingly, the sealing effect is good, glue leakage is prevented, and the situation that the glue using quality is influenced is also prevented; and the sealing gasket is used for strengthening sealing, during sealing, the bottom face of thesealing gasket abuts against the end of the pipe opening, and the top end of the sealing gasket abuts against the cover body.
