Description

Technical Field

[0001] The utility model relates to the application field of door and window components, in particular to a door and window screw rod transmission structure. Background Art

[0002] The principle of electric doors and windows is to drive the door and window sashes to move up and down in the door and window slot frames through a transmission structure to achieve the opening and closing function. In recent years, electric lifting glass doors and windows have emerged in the sun room and enclosed balcony application market and have gradually developed on a large scale.

[0003] The chain drives and rack drives currently available on the market are summarized as follows:

[0004] 1. Chain drive: widely used in situations where the two axes are far apart. The polygonal effect of chain drive causes uneven movement and generates noise. The polygonal characteristics of chain drive are used in electric glass doors and windows, which can easily cause the glass leaf and the guide groove frame to get stuck, causing overload and the risk of the glass leaf extruding due to hard squeezing;

[0005] 2. Rack drive: widely used in industrial facilities, with high transmission accuracy and smooth operation. The gears and racks are made of high-strength alloy steel or cast iron. The rack drive feature is rigid transmission, which has no overload protection. The electric glass fan and the guide groove frame may get stuck or overloaded, which may easily lead to common failure factors of rack drive and further cause systemic risks.

[0006] In summary, chain drive and rack drive are not suitable for electric lift balcony window scenarios; the transmission structure with high transmission accuracy, smooth operation, no noise, and no jamming between the universal adaptive door leaf and the guide groove frame under gravity load has not yet proposed an effective solution to the problems in the related technologies of electromechanical facilities of glass lift balcony windows. We propose an electric glass door and window screw transmission structure with a detachable and universal gravity adjustment device to solve the above problems. Utility Model Content
