Abstract
This utility model provides a concealed drainage structure for aluminum alloy doors and windows. The concealed drainage structure for aluminum alloy doors and windows includes a bottom frame mechanism and a window sash. The concealed drainage structure for aluminum alloy doors and windows provided by this utility model, by setting multiple first drainage holes, second drainage holes, and drainage holes, includes multiple first drainage holes, second drainage holes, and drainage holes in the bottom frame structure. The first and second drainage holes are located at the outermost step position on the upper edge of the bottom frame. The middle of the step surface at this position bulges upwards, forming two slopes. The first and second drainage holes are located on the inner and outer sides of the two slopes, respectively. The multiple first drainage holes can be concealed by the middle step, while the second drainage holes can be concealed by the blocking strip on the outer frame edge. The multiple drainage holes are located in the strip-shaped groove on the outer frame edge, so that the drainage structure of the bottom frame structure is concealed under normal conditions, thus not affecting the overall aesthetics of the structure.
