Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a dual-purpose screen curtain. Background Technology

[0002] With the improvement of people's living standards, there are now more and more types of curtains, such as roller blinds, vertical blinds, and screen curtains. Screen curtains are a type of hanging curtain, consisting of multiple screen curtain panels arranged in parallel to achieve functions such as light blocking, separation, and aesthetics. They are mainly divided into motorized screen curtains and manual screen curtains. Manual screen curtains generally use a track to install one screen curtain panel at a time, and the position of the screen curtain panels on different tracks is manually moved to achieve parallel or overlapping arrangements between the screen curtain panels. Depending on the installation length and the width of the curtain panels, it requires a custom track with multiple parallel track grooves, which is more expensive and the manual operation is relatively cumbersome. Motorized screen curtains, such as the one described in application number 202420290692.7, include an electric drive device and a curtain track. The curtain track has multiple relatively parallel track grooves. It changes the traditional customized fixed structure of curtain tracks by setting up a main track and an extension track that are connected by plugs. The number of track grooves can be increased or decreased according to the user's actual needs to meet the user's needs for adjusting the number of curtain panels. However, it has at least two sets of track slots and can only be driven by a motor. It cannot be manually or electrically driven according to customer needs, nor can it be modularly customized.

The driving gear, driving gear, and driven gear are respectively mounted via bearings.

[0017] The inner side of the annular belt is provided with teeth, and the driven gear is provided with a moving gear part that meshes with the teeth, so that the main gear part, the connecting gear and the driven gear are driven in sequence through the driving gear, thereby realizing that the annular belt drives the suspension assembly to move.

[0018] Preferably, the suspension assembly includes a first movable slider and a second movable slider connected to the movable slat, and a first slave slider and a second slave slider connected to each slave slat. The first slave slider of the slave slat adjacent to the movable slat is located between the first movable slider and the second movable slider, so that when the annular belt drives the second movable slider to slide to abut against the first slave slider of the slave slat adjacent to the movable slat, the slave slat adjacent to the movable slat will be moved to unfold; when the annular belt drives the second movable slider to slide to abut against the second slave slider of the slave slat adjacent to the movable slat, the slave slat adjacent to the movable slat will be moved to fold.

[0019] Preferably, the track module further includes several sets of secondary track beams arranged parallel to the main track beam. Each set of secondary track beams is provided with a secondary slide rail cavity that slides along its length.
