Winding method and winding device for venetian blinds or honeycomb blinds

Abstract

A method and device for winding venetian blinds or honeycomb blinds, one ends of said multi-strand lift cords are fixedly connected with the underbeam of the venetian blinds or honeycomb blinds, while the other ends pass through the slats of the venetian blinds or honeycomb blinds converge into a strand rope; and finally the strand rope is fixedly connected with a winding reel which is rotated to wind the rope to realize the action of winding. The winding method of many cords in one is used in the present invention. The purpose of controlling the whole set of venetian blinds or honeycomb blinds is achieved by controlling a rope with a winding reel. The venetian blinds or honeycomb blinds of the present invention with simpler structure, more convenient installation, longer operating life, better lifting balance of the blinds, more beautiful products, and less influences of the window size.

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 cords. [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.
