The invention discloses a closing method for a vacuum glass pumping hole. The method comprises the following steps of: on the surface of the outer side, contacting an air pumping device, of a glass plate, pre-manufacturing a metallic layer fixed on the glass plate around the air pumping hole; and after air pumping, performing the pressure tight welding connection between a sealing member and the metallic layer around the air pumping hole by the metallic brazing process to realize the closing of the air pumping hole. The invention also provides a closing structure and a closing device for the vacuum glass pumping hole. Compared with the traditional closing method for the air pumping hole, the method disclosed by the invention has the advantages that the air pumping hole can be more reliably and tightly closed; the closing structure is stable, and the service life is prolonged; the outer surface of the sealing member is flushed with the glass plate, so that the later movement and installation of the vacuum glass are more convenient; and the sealing member and the metallic layer are instantly welded, so that the performance of toughened glass or semi-toughened glass materials is not affected.
