[0002] Doors and windows, depending on their location, are classified as either enclosure components or partition components, and are important parts of the building's enclosure structure system. Depending on different design requirements, they possess functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fireproofing. At the same time, doors and windows are also important components of architectural form (playing a significant role in the contrast between solid and void, and in creating rhythmic artistic effects). Therefore, their shape, size, proportion, arrangement, color, and style have a significant impact on the overall architectural design.

[0003] A search revealed an application with application number CN202322170253.0 for an adjustable-gap safety door and window, comprising an inner frame assembly, wherein the outer wall of the inner frame assembly is provided with pulleys, and an outer frame assembly is movably connected to the outer wall of the inner frame assembly via the pulleys; the inner frame assembly includes an inner frame disposed on the inner wall of the outer frame assembly, the inner wall of the inner frame is provided with a fixing strip, the inner wall of the fixing strip is provided with a screw, and a stop bar is fixedly connected to the inner wall of the fixing strip via the screw;
