Description

Technical Field

[0001] The utility model relates to the field of curtain installation, in particular to a curtain installation structure. Background Art

[0002] Projectors are video playback devices that are commonly used in many family meetings. Projectors are used in conjunction with projection screens, which can make the projection clear. There are many types of projection screens, and the most commonly used are retractable and winding screens, which are low in price and widely used. When this type of screen is in use, it will be released through a winding mechanism, and when it is not in use, it will be collected through a winding mechanism. This is to ensure that the screen will not be dirty and to ensure the quality of projection.

[0003] Most traditional winding mechanisms are composed of a roller, a connecting shaft, a connecting seat, a tubular motor and other components. When in use, the screen is mostly fixed to the outer wall of the roller by gluing. When the tubular motor drives the roller to adjust forward and reverse, the roller can drive the screen to rise and fall. However, if the gluing method is insufficient in bonding strength, the screen is likely to loosen or fall off the roller over a long period of time. If the bonding strength is strong, the screen cannot be completely disassembled once it is damaged, and the glued part will adhere to the surface of the roller and be difficult to clean, making it impossible to quickly disassemble and assemble the screen.

[0004] Therefore, it is necessary to invent a mounting structure for a curtain. Utility Model Content
