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.

[0002] Background technique

[0003] 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. ...

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] see figure 1 , a rotary adjustable shutter, comprising an outer leaf 17, the middle of the outer leaf 17 is provided with a circular void 18; the circular void 18 is provided with a circular inner leaf 19; the inner leaf 19 Each of the inner blades 8 can be turned over synchronously independently of the outer leaf 17; the inner leaf 1) can rotate 360° on the vertical plane independently of the outer leaf 17 as a whole.

[0027] The outer leaf window 17 adopts the following structure: it is composed of an upper beam 1, a group of outer blades 3, an outer leaf turning mechanism 2, an outer leaf window handle 4 and an outer leaf hanging rope 5;

[0028] Wherein, the upper crossbeam 1 is fixed on the wall installation position, and the concrete crossbeam 1 can be fixed on the wall above the covered window of the present invention;...
