Technical Field
[0001] The utility model relates to the field of rolling shutter door installation, in particular to a rolling shutter door bracket. Background Art
[0002] Rolling doors are constructed with multiple hinged panels connected in series. The doors rotate up and down within a fixed slideway, pivoting around a reel above the door. The reel operates by rolling up and down the door curtain, enabling opening and closing. The reel system of a rolling door consists of a reel, reel bearings, reel core, and reel core support. These components work together to achieve the reeling and retraction of the door curtain. When the reel rotates, the door curtain is rolled up, opening the door; when the reel stops, the door curtain is pulled down, closing the door. This principle makes opening and closing a rolling door extremely simple and quick.
[0003] The currently commonly used rolling shutter doors have a fixed upper drum. When the rolling shutter door is opened, when more curtain pieces are wound on the drum, the diameter of the drum wrapped around the curtain pieces becomes larger, causing the relative position of the curtain pieces and the track to shift, causing the curtain pieces to collide with the track.
