Blind window capable of being automatically closed under strong sunlight irradiation

Abstract

The invention relates to the technical field of a blind window, and discloses a blind window capable of being automatically closed under strong sunlight irradiation. The blind window capable of beingautomatically closed under strong sunlight irradiation comprises a framework, wherein a regulating rod is movably connected inside the framework; clamp blocks and a driven wheel are fixedly connectedto the outer side of the regulating rod; a regulating rope is arranged at the outer side of each clamp block; curtain sheets are arranged at the bottom parts of the regulating ropes; a threaded rod isengaged with the outer side of the driven wheel; and the top of the threaded rod is fixedly connected with a transmission gear. Low-boiling-point liquid contained in an inner cavity of an expansion body is heated to evaporate under the sunlight irradiation, so that the air pressure inside the expansion body is increased, so that a heat exchange cavity communicating with the expansion body througha connecting pipe expands; a slide block and a slide rod are driven to rightwards slide in a process that a combination body of a heated cavity and the heat exchange cavity rightwards extends; when external sunlight reaches a certain intensity, teeth, moving to the right side of the slide rod, of the slide rod are in contact with and engaged with the transmission gear; and the slide rod drives the transmission gear to rotate.

Description

technical field [0001] The invention relates to the technical field of blinds, in particular to a blinds that can be automatically closed when exposed to strong sunlight. Background technique [0002] As the name suggests, the venetian blinds have a plurality of horizontally arranged long plate-shaped curtains, and these curtains are suspended between the upper beam and the lower beam by ladder ropes, and the curtains are spaced from top to bottom. Expand or stack from bottom to top to determine the shaded area of ​​the slats. [0003] Blinds have many functions and advantages, and are very beautiful. They are generally used in high-rise buildings. At present, computers are used for office work in public office places such as office buildings. , will prevent the office staff from seeing the display, and need to close the curtain to prevent sunlight from entering the room.
