ROLLER BLIND BALANCE REGULATOR AND ROLLER BLIND COMPOSED THEREOF
Disclosed are a roller blind balance regulator and a roller blind composed thereof. The roller blind balance regulator includes a stepped shaft and a friction cylinder, where the stepped shaft is provided with an external thread, the stepped shaft penetrates the friction cylinder, the friction cylinder is provided with an internal thread and is in threaded connection with the stepped shaft, and a friction layer is arranged between the friction cylinder and the stepped shaft. The roller blind includes a roller blind rod, a blind fabric, two mounting members, and the roller blind balance regulator, and a return spring is arranged in the roller blind rod. In the present invention, the roller blind rod drives the friction cylinder to rotate, so that the friction cylinder axially moves along a limiting screw while rotating, thereby increasing or decreasing a friction force between the friction cylinder and the friction layer.
