While screen doors serve to prevent insects from entering and allow wind and light to pass through, there were concerns that they could be easily opened and closed from the outside, and that people could easily break through the mesh and gain entry. There were also concerns that they could not be used when it was raining because rain would get in. However, there were challenges with screen doors, as they come in many sizes and colors, and their usable thickness is limited. [Solution] To prevent people and rain from easily entering within the limited thickness of the screen door, the lattice is woven in a specific way, guiding the direction of warping when the lattice expands due to heat, and it is fixed to a support rod to prevent the screen door from being opened or closed. Even if the screen door itself is damaged, an alarm device installed inside the frame deters entry, and a perforated film prevents rain from entering, thus solving the problem.

This utility model relates to the field of garden window technology, and discloses a garden window landscape device, including a schematic wall, a support frame, and a connecting mechanism. The connecting mechanism includes a circular frame and four square frames. A pair of inserts are fixedly connected to the notches around the four sides of the circular frame. A pair of sliders are fixedly connected to the four corners of the inner wall of the support frame. A fixing mechanism is provided inside the square frames. The fixing mechanism includes four threaded rods and four threaded cylinders. The outer walls of the threaded rods are threadedly connected to the threaded cylinders, and both ends of the threaded cylinders are rotatably connected to the inner walls of the square frames. In this utility model, by passing the threaded rods through the square frames in the fixing mechanism, the movable blocks extend out of the support frame and engage with the slots, thus fixing the garden window. The rotation of the threaded cylinders causes the threaded rods to retract the movable blocks into the slots, releasing the engagement and facilitating disassembly and assembly by workers.
