<p>Hollow glass with an internal sunshade, comprising two pieces of glass medium (6), a sunshade between the two pieces of glass medium (6), a traction mechanism (8) controlling the sunshade, and a traction device (5) fixed thereon. An operating device (1) is provided at a position corresponding to the traction device (5) on the outside of the hollow glass. At least one of the operating device (1) and the traction device (5) is provided with a magnetic material (41) connecting the two devices by magnetic force. At least one of the two devices includes a first support structure (21); a first rotation shaft (71) is fixed on the first support structure (21); a roller (31) having a resistance position is installed on the first rotation shaft (71); and the roller (31) enables the magnetic force to change according to the change of position, thereby achieving automatic limitation of the sunshade.</p> |
