Description

Technical Field

[0001] The utility model relates to the technical field of electric telescopic doors, in particular to a windproof device for electric telescopic doors. Background Art

[0002] Electric telescopic door is also known as "electric door" or "electric folding door". Electric telescopic door is mainly composed of door body, drive and control system. The door body of telescopic door is made of high-quality aluminum alloy and ordinary square tube, and is hinged by parallelogram principle, which is flexible and has large telescopic travel.

[0003] Since traditional electric telescopic doors do not have a good fixing device at the bottom, they often cannot withstand the wind force in a typhoon environment when they are unfolded, causing the door body to leave the ground. When the wind is stronger, the electric telescopic door may even flip over and fall down, which not only poses a threat to the safety of the building, but also causes property loss and risk of casualties. Utility Model Content
