<p>A moving method of combined-type louver blades of a window blind, and a window blind. The louver blades comprise main louver blades (90) and sub-louver blades (91, 92, 93). One or more sub-louver blades (91, 92, 93) are arranged between each pair of main louver blades (90). The sub-louver blades (91, 92, 93) go up and down in a horizontal direction along with the main louver blades (90), and can also go up and down in the horizontal direction relative to the main louver blade (90). The sub-louver blades (91, 92, 93) can turn over along with the main louver blades (90), and can also turn over relative to the main louver blades (90). A driver (4) and a lift turner (3) of the window blind are arranged in a top rail (1); a hexagonal shaft (2) passes through the driver (4) and the lift turner (3). A connecting bead chain (42) of the driver (4) rotates the hexagonal shaft (2) through the driver (4), thereby driving the lift turner (3) to rotate. A lift cord (7) passes through a louver blade assembly (9). An upper end of the lift cord (7) is connected to a lift wheel (32) in the lift turner (3), and a lower end thereof is connected to a main bottom rail (100). Upper ends of front and rear ropes of a sub-ladder tape pass through a ladder tape hole (386) of a base (38) of the lift turner (3), and are embedded into an annular groove of a turnover drum (354) of a roller mechanism (35) of the lift turner (3), and then enter a top hole (3545) of the turnover drum (354) and are fixed in the roller annular groove through a pin (35113). Upper ends of front and rear ropes of a main ladder tape (8) pass through the ladder tape hole (386) of the base (38) of the lift turner (3), and then are embedded into an annular groove (3544) of the turnover drum (354) of the roller mechanism (35) of the lift turner (3), and fixed in the annular groove of the turnover drum (354) through a pin (3547). With the louver blade combination structure, louver blades of a combined-type window blind with a variable pitch are capable of performing various operations to satisfy user requirements for indoor visual comfort and thermal comfort.</p> |
