CORDLESS ROLLER BLIND
A cordless roller blind includes a roller tube (1), a blind fabric (2) wound around the roller tube (1), and at least one brake device (4). A coil spring (23) is arranged in the roller tube (1), and the torsion of the coil spring (23) changes as the roller tube (1) rotates. The torsion force of the coil spring (23), the friction force provided by the brake device (4) and the weight of a hanging portion of the blind fabric (2) are mutually balanced, so that the blind fabric (2) remains stationary at any position without an external force. In the provided cordless roller blind, the blind fabric (2) can be manually raised or lowered as required in use and self-locked in the desired position, and the roller tube (1) itself and a limiting component are not subjected to excessive torque during the self-locking process to avoid irreversible damage.
