The invention relates to the technical field of construction materials, in particular to a household anti-theft aluminum alloy window. The anti-theft window comprises a fixing mechanism, a mounting hole, a water baffle, an opening mechanism, a planting mechanism, a pulling mechanism, a third aluminum alloy frame, a driving mechanism, a reinforcement mechanism, a water storage mechanism and a mounting box; a slide frame of a rectangular structure is installed on the side wall of the third aluminum alloy frame, a slide plate with basin grooves in the surface is slidingly connected to the interior of the slide frame through pulleys, the driving mechanism is matched with the pulling mechanism, the slide plate can quickly move in the slide frame for photosynthesis, and the carrying time is shortened; the slide plate is moved to the bottom of the water baffle through the driving mechanism, and green plants can be prevented from being damaged through pouring of rainwater under rainstorm weather; the included angle between the third aluminum alloy frame and the slide frame is larger than 90 degrees, rainwater return is avoided, the water baffle is installed on the side wall of a second aluminum alloy frame, a water tank is fixedly connected to the bottom of the water baffle, and water of the water tank flows into a water storage pond through a connection pipe; a water outlet pipe is arranged at the bottom of the water storage pond, green plants are conveniently covered with pipes, and water resources are saved.
