Multipurpose type Venetian blind capable of changing distances between shafts

Abstract

The invention provides a multipurpose type Venetian blind capable of changing distances between shafts and relates to the technical field of Venetian blinds. The multipurpose type Venetian blind capable of changing the distances between the shafts comprises a wall body; a window frame is fixedly mounted in the wall body; blades are rotationally connected to the interior of the window frame throughrotating shafts; first guide rail grooves are formed in the two sides of the window frame; rotating rods are rotationally connected to the two ends of the rotating shafts; connecting rods are rotationally connected to the other ends of the rotating rods of the adjacent rotating shafts; threaded rods are rotationally connected to the bottom of the window frame; and a knob is fixedly mounted at theleft end of the threaded rod. According to the multipurpose type Venetian blind capable of changing the distances between the shafts, the blades can be intensively collected at the top of the windowframe by reducing the distances between the rotating shafts when the Venetian blind is not needed; and therefore, the indoor vision can be enlarged while the wind resisting strength of the Venetian blind is guaranteed; and as the relative distances between the blades can be adjusted, the practicability of the Venetian blind is enhanced.

Description

technical field [0001] The invention relates to the technical field of venetian blinds, in particular to a multipurpose venetian blind capable of changing the distance between axes. Background technique [0002] Blinds are a style of windows. They are curtains made up of multiple blades arranged in an orderly manner. By changing the angle of inclination of the blades, it is possible to ensure that the curtains can shade the sun while maintaining ventilation. Compared with some windows and Curtains have greater advantages and are very beautiful. They can be used as soft decorations in new homes and are often used in high-rise buildings. [0003] However, during the use of the blinds, no matter it is tilted at any angle, the blades will exist at the window. People can only observe the outdoors through the gaps between the blades, and when they are far away from the blinds, they cannot observe the surrounding things at all. Rollable blinds have appeared, but the rolling of the...

[0003] However, during the use of the blinds, no matter it is tilted at any angle, the blades will exist at the window. People can only observe the outdoors through the gaps between the blades, and when they are far away from the blinds, they cannot observe the surrounding things at all. Rollable blinds have appeared, but the rolling of the blinds requires the blades and the connecting device to be made of soft materials. Such blinds are easily damaged and deformed when encountering large airflows, and the distance between the rotational axes of the blades of traditional blinds They are all fixed, so when the blades are tilted, the relative distance between the parallel blades is also fixed, which cannot be adjusted according to the wind force and the inclination angle of sunlight, which limits the practicability of the blinds
