Description

Technical Field

[0001] This utility model relates to the field of blind technology, and more specifically, it relates to a combined blind and screen window. Background Technology

[0002] In existing technologies, combined venetian blind and screen devices often suffer from shortcomings in the adjustment and fixation of the venetian blind slats. In most existing venetian blind designs, the slats are usually adjusted by rotating them, but this method is often not precise enough and cannot achieve step-by-step adjustment of the slat angle. The angle adjustment of the slats is only carried out through a simple rotating mechanism, usually through a rotating rod or shaft, but its accuracy and stability are low. Therefore, users cannot make fine adjustments to the angle of light entering according to their needs, resulting in insufficient flexibility in light adjustment and an inability to fully meet the lighting requirements of different environments.

[0003] In existing technologies, many venetian blind designs connect the slats to the window frame via pivots or hooks. However, this connection method often fails to effectively ensure the slats remain fixed after adjustment. Even if the user successfully adjusts the blinds to the desired angle, the slats often cannot be securely fixed in the designated position, making them prone to shifting or loosening due to external forces, thus affecting the window's usability.

[0004] While some designs feature adjustable slats, these slats cannot be easily and conveniently secured after adjustment, requiring additional fixing measures such as manual reinforcement or screw locking. This undoubtedly increases the complexity and cumbersomeness of use. For users, frequent fixing and adjustment significantly reduces the practicality of the window. Utility Model Content
