This application discloses a retractable smoke curtain, belonging to the technical field of smoke curtains. It includes a fixed frame with a telescopic mechanism inside. The telescopic mechanism includes a first telescopic section fixedly installed inside the fixed frame. A second telescopic section is slidably connected inside the first telescopic section. Both the first and second telescopic sections have two sets of slide rails inside, with sliders slidably connected to the slide rails. A first spring is installed at the top of each slider and is mounted on the top of the telescopic mechanism. The second telescopic section is slidably connected to the first telescopic section via the two sets of sliders located inside the first telescopic section. A screw is threadedly connected to the bottom of the first telescopic section below one set of sliders, and a stop block is rotatably connected to the top of the screw. An elastic limiting mechanism is provided on one side of the bottom of each set of first telescopic sections below one set of sliders. This application improves the flexibility and adaptability of smoke-blocking materials through the telescopic mechanism.
