a blind that closes automatically when exposed to strong sunlight

Abstract

The invention relates to the technical field of shutters, and discloses a shutter that can be automatically closed when exposed to strong sunlight, including a frame, an adjustment rod is movably connected to the inside of the frame, and a locking block is fixedly connected to the outside of the adjustment rod and a driven wheel, an adjustment rope is installed on the outside of the block, a curtain is installed on the bottom of the adjustment rope, a threaded rod is engaged on the outside of the driven wheel, and a transmission gear is fixedly connected to the top of the threaded rod. The inner cavity of the expansion body is provided with a low-boiling point liquid, which is heated and evaporated under the sunlight, and the air pressure in the expansion body increases, which makes the heat exchange chamber connected to the expansion body through the connecting pipe expand, so that the combination of the heating chamber and the heat exchange chamber moves toward the During the right extension, the slider and the slide bar are driven to slide to the right. When the external sunlight reaches a certain intensity, the slide bar moves to the right side of the slide bar to engage with the transmission gear, and the slide bar drives the transmission gear to rotate.
