Winding method and winding device for venetian blinds or honeycomb blinds

Abstract

The invention discloses a winding method and winding device for venetian blinds or honeycomb blinds, which are characterized in that one ends of multiple lifting pull-ropes are fixedly connected with a lower bolster of a venetian blind or a honeycomb blind, the other ends of the lifting pull-ropes passing through the venetian blind or the honeycomb blind are converged into a pull-rope, and finally, the pull-rope is fixedly connected to a winding reel, and then, the winding reel rotates and winds the pull-rope to realize a winding action. In the invention, a multi-rope integrated winding mode is innovatively adopted, and a pull-rope is controlled by a winding reel, so that the purpose of controlling a whole set of venetian blinds or honeycomb blinds can be achieved; the winding device is simpler in structure, more convenient to install, longer in service life and better in balance degree of venetian blinds; the products are more beautiful, the influence of the size of a window body is smaller; and a bottleneck that small-sized products can not be manufactured because the internal space of the window body is limited at present is broken through, therefore, the method and device disclosed by the invention can be widely applied to electric sun-shading hollow glass devices.

Description

technical field [0001] The invention relates to the field of door curtains, in particular to a lifting and winding method and device applied to venetian blinds or honeycomb blinds. Background technique [0002] The main components used for electric sunshade hollow glass inner venetian blinds or honeycomb blinds are flat belts and pull ropes. [0003] The thickness of the sling is generally 0.16-0.22mm. Because the thickness is too small, it will rub against the louvers when the louvers are raised and lowered, resulting in fluffing of the slats. Bring losses to manufacturers and customers. Furthermore, the current louver lifting structure is realized by superimposing flat belts, but for hollow products, the hollow space between double-layer glass is limited, which makes it impossible to manufacture louvers with too high height.

AI Technical Summary

Problems solved by technology

[0003] The thickness of the sling is generally 0.16-0.22mm. Because the thickness is too small, it will rub against the louvers when the louvers are raised and lowered, resulting in fluffing of the slats. Bring losses to manufacturers and customers

In addition, the current lifting structure of the louvers is realized by superimposing flat belts, but for hollow products, the hollow space between double-layer glass is limited, which makes it impossible to manufacture louvers with too high height

[0004] Pull cords are also widely used to control the lifting of louvers. Generally, in order to keep the louvers in a horizontal state for lifting, it is generally necessary to set at least two lifting pull cords. However, in the existing structure, each pull cord needs to be equipped with a reel device, since each winding device has a certain length, and a drive device (such as a motor) needs to be installed in a limited space, resulting in the inability to manufacture small-sized louvers

Moreover, because the wire reels are independent, the working conditions of each wire reel are difficult to keep completely synchronized, which makes it difficult to balance the lifting of the shutters controlled by multiple pull cords.
