This utility model discloses a combined transition slider and an external
louver control
assembly and an external louvered
glass window containing it. The combined transition slider includes a first transition slider and a second transition slider that snap together. Both the first and second transition sliders include a strip-shaped body with rollers rotatably connected to both ends. A mounting groove is formed in the middle of the body, and a permanent
magnet is installed in the mounting groove. One end of the first transition slider is connected to a buckle, and one end of the second transition slider has a groove that matches the outline of the buckle. The buckle is movably engaged in the groove, connecting the first and second transition sliders end to end. The permanent magnets on the first and second transition sliders are on opposite sides. When this combined transition slider is installed on a triple-glazed, double-cavity external louvered
glass window, the first and second transition sliders only individually attract the
louver traction slider and the internal control slider, respectively. The magnetic force is sufficient, and the two sliders work together to achieve a transition traction effect.
