Description

Technical Field

[0001] The utility model relates to the technical field of shutter fixing, and more particularly to a shutter fixing structure. Background Art

[0002] In the current blinds fixing structure technology, there are generally some operational and installation problems, which not only affect the user experience, but may also lead to safety risks.

[0003] First of all, the existing blinds fixing structures mostly rely on manually operated pull cords to control the opening and closing of the blinds blades. This traditional operation method is cumbersome, time-consuming and labor-intensive. The user needs to pull the pull cord repeatedly to achieve the ideal degree of blade opening and closing, which not only increases the labor intensity of the user, but also in some cases, such as high-rise buildings or large blinds systems, manual pull cord operation may even pose a safety hazard. In addition, long-term manual operation may also cause wear of the pull cord, further affecting the service life and reliability of the blinds.

[0004] Secondly, in the existing technology, the process of fixing the blinds to the installation position is usually rather cumbersome. Since the structures and sizes of the blinds vary, they need to be precisely aligned and fixed during installation, which often requires users to have certain technical knowledge and installation experience. For ordinary users, this process may seem complicated and difficult to master, which not only increases the difficulty of installation, but may also result in poor performance of the blinds or safety hazards due to improper installation.

[0005] In addition, although some devices designed to simplify the fixing and installation of blinds have appeared on the market, the structures of these devices are usually simple and the mechanisms are not perfect. These devices may include some quick fixing clamps or simple installation brackets, which can theoretically speed up the installation, but due to structural deficiencies, they often cannot provide sufficient stability and reliability. In actual use, these simple fixing structures are easily affected by external forces such as wind and vibration, which may cause the fixing structure to loosen or even fall off, which not only affects the normal use of the blinds, but may also have an adverse effect on the appearance and safety of the building.
