Louver Blade Transmission Structure for Clear Rack Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for synchronous rotation of louver blades face issues such as view obstruction, inconvenient mounting due to obscured rack adjustments, potential gear disengagement, and restricted blade rotation, especially when the window sash vertical column is moved.
Innovation Solution
A transmission structure with a mounting bar featuring a front side opening, allowing clear observation and adjustment of gear-rack meshing, and using detachable connections between gears, racks, and a rotating shaft to prevent gear disengagement and ensure smooth blade rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gear passes through the window sash vertical column to mesh with the racks, then the blade rotation is achieved, but the rack position needs to be repeatedly adjusted and the meshing condition cannot be clearly observed
Solution Approach 1:
The mounting bar is divided into separate components (left side plate, right side plate, rear side plate) with through holes that allow the gear to be assembled through. This segmentation enables the gear to pass through the window sash vertical column while providing clear access points for observation and adjustment of the meshing condition between the gear and racks.
2Ease of operation
If the gear and racks are meshed with a gap to facilitate blade rotation, then the blade can rotate smoothly, but the gear is prone to falling off when the window sash vertical column is moved
Solution Approach 1:
The mounting bar serves as an intermediary structure that provides both the gap necessary for smooth blade rotation and the mechanical support to prevent gear disengagement. The through holes in the mounting bar allow the gear to be securely positioned while maintaining the required clearance for rotation.
3Adaptability or versatility
If multiple gears are provided for multiple blades, then all blades can be rotated synchronously, but the rack positions must be repeatedly adjusted for each gear
Solution Approach 1:
The mounting bar structure with its standardized through holes and side plates serves as a universal platform that can accommodate multiple gears at different positions. Once the mounting bar is in place, multiple gears can be installed simultaneously without requiring repeated adjustment of rack positions, as the entire assembly is designed to work together as a unified system.

AI summary
A transmission structure for synchronous rotation of louver blades includes a mounting bar inserted in a window sash vertical column. The mounting bar has an open front side and includes a left side plate, a right side plate and a rear side plate; a left rack is slidably arranged on the right side of the left side plate; a right rack is slidably arranged on the left side of the right side plate; a plurality of gears arranged at intervals in the vertical direction are meshed between the left rack and the right rack; through holes, the number and positions of which match the gears, are formed in the rear side plate; the rear end of a rotating shaft for driving blades to rotate passes through the window sash vertical column to be detachably connected to the gears.
