Rotary adjustable shutter

Abstract

The invention discloses a rotary adjustable shutter which comprises an outer shutter body. A circular opening is arranged in the middle of the outer shutter body, a circular inner shutter body is arranged in the circular opening, and the inner shutter body is mainly composed of an inner shutter body upper beam, an inner blade turning mechanism, a group of inner blades, a horizontal connection rod, an inner shutter turning handle, a turning handle and an inner blade lifting rope. The inner shutter body can turn relative to the outer shutter body through the turning handle, and the inner blades can turn synchronously through turning of the inner shutter turning handle. The rotary adjustable shutter has the advantages of being capable of adjusting angles of the blades relative to incoming sunlight, effectively blocking sunlight radiation with window irradiating angles changing continuously along with time, and simultaneously being capable of meeting requirements for ventilation and full sunshade.

Description

technical field [0001] The invention relates to a shutter, in particular to a rotary adjustable shutter, which belongs to the technical field of ventilation engineering. Background technique [0002] The shutters widely used in the prior art generally have two types of blade arrangement: horizontal arrangement and vertical arrangement. Among them, the louvers with horizontal blades are more effective in blocking the solar radiation from above the louvers, and are easy to block the southward radiation; while the louvers with vertical blades are better in blocking the radiation from the horizontal direction of the louvers, and are more effective in preventing the sun from the west. efficient. But in fact, the angle at which sunlight enters the window changes with time, and most of the time it is obliquely incident, that is to say, it is difficult for blinds with blades fixed to be horizontally arranged or vertically arranged to effectively block sunlight radiation.

AI Technical Summary

Problems solved by technology

But in fact, the angle at which sunlight enters the window changes with time, and most of the time it is obliquely incident, that is to say, it is difficult for blinds with blades fixed to be horizontally arranged or vertically arranged to effectively block sunlight radiation.

[0003] In addition, when using shutters, in order to ensure ventilation, the blades of the shutters need to be flipped open at a certain angle, but at this time there will be a lot of sunlight entering the room (especially in summer when the sunlight is relatively strong); Flip the shutter blades closed, but this will affect the ventilation in the room, making people feel stuffy

[0004] To sum up, the blinds in the prior art have the following problems: the direction of the blades is fixed, which is difficult to meet the needs of solar radiation shielding; the blade adjustment method is single (when blocking the light from a certain direction, the amount of shading can only be adjusted by flipping the blades ), ventilation and adequate shading cannot be satisfied at the same time
