Venetian blind folding and unfolding mechanism and electric blind window thereof

Abstract

The invention discloses a venetian blind folding and unfolding mechanism, and belongs to the technical field of shutters. The venetian blind folding and unfolding mechanism comprises a shear fork type lifting mechanism, venetian blind clamps clamped at the ends of venetian blinds and a rotating mechanism for controlling the venetian blind clamps to rotate, and the venetian blind clamps are rotatably connected to shear fork nodes of the shear fork type lifting mechanism. Lifting and opening and closing of the shutter blind are controlled through the shear fork type lifting mechanism and the rotating mechanism respectively, lifting and opening and closing do not interfere with each other, the requirement for multiple functions of the shutter can be met, and the curing mode of lifting opening and lowering closing is broken through. The invention further provides an electric shutter which comprises a shutter blind and a main frame body surrounding the shutter blind, the folding and unfolding mechanism is installed in the main frame body, and a storage box is installed on the top of the main frame body. An angle adjusting device for controlling the rotating mechanism, a driving device for driving the shear fork type lifting mechanism and a lifting device for storing the shutter blind into the storage box are arranged in the storage box, and after the shutter blind is stored in the storage box, protection can be formed, and the overall attractiveness of the shutter can be improved.

Description

technical field [0001] The invention relates to the technical field of blinds, in particular to a retractable mechanism for a blind and an electric blind. Background technique [0002] Blinds originated in China and are a style of windows. The blinds have flexible blades. Compared with traditional fabric curtains, they have a better sun-shading effect and are more convenient to retract and retract. They are simple and generous, and do not take up space, which is in line with the simple style that the public has begun to pursue. Most of the current shutters use manual pulling ropes to realize the lifting and rotation of the shutter blades, and the automation and intelligence are relatively low. In recent years, with the advancement of science and technology, electric blinds driven by motors have gradually emerged. However, the current electric blinds can only adjust the rotation angle of the louver blades to realize the opening and closing of the blinds, and cannot realize t...

Problems solved by technology

However, since the lifting of the venetian blind and the closing of the louver are still carried out synchronously, that is, whether it is folded counterclockwise or clockwise, the height of the blade and the rotation angle of the blade at this time must match each other, that is, when the blade is raised to the highest , the angle of the blade must be fully open, and when the blade drops to half, the angle of the blade must be half-open, which in turn causes many restrictions and cannot meet the needs of various situations

If the blinds are only required to be raised halfway, and the blades are required to be fully closed or fully expanded, this is not possible in the above-mentioned patents.

Moreover, the process and method of transforming the shutters of the above patent from the lowered closed state to the half lowered open state are too complicated and cumbersome, and the conversion time is long, which cannot meet the needs of fast-paced life for simple and rapid lifting and opening and closing of the shutters.
