[0002] Built-in blinds insulating glass has the advantages of heat preservation and sound insulation of ordinary insulating glass and the convenient dimming performance of blinds. It is beautiful, generous, easy to operate, clean, hygienic and space-saving, so it has been more and more widely used at home and abroad. Common built-in blinds insulating glass is divided into ordinary single-chamber built-in blinds insulating glass and three-glass two-chamber built-in blinds insulating glass; the former is composed of inner glass, outer glass, frame, blinds blades, and blade adjustment mechanism composed of blade lifting mechanism and blade flipping mechanism; the latter is added with a layer of middle glass between the inner and outer glass of the former, which divides the space between the inner and outer glass into inner and outer cavities, further improving the heat preservation and sound insulation effects.

[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN216841366U discloses a manually rotating magnetic transmission device for sunshade hollow glass.
