Roller blind locking system

A locking system for a roller blind includes a plurality of roller blind slats including a guide track with a U-shaped guide channel having a channel base and first and second channel walls. A locking bar is coupled to the roller blind slat. In the locked position, the locking bar extends transversely to the channel base. The locking bar has a notch covered by the disconnect wall, and the locking bar disconnects the disconnect wall from aligning with the channel base in the locked position. The locking bar may be slidably received in a sleeve positioned in the guide channel to increase resistance to torsional forces on the locking system. In an alternative embodiment, the locking system includes a one-piece squeeze body, a locking bar, and a handle. A longitudinal channel is integrally formed in the body for receiving the locking bar and the handle. 用于卷帘的锁定系统，包括多个卷帘板条，包括带有U形引导通道的引导轨道，该引导通道具有通道基部以及第一通道壁和第二通道壁。锁定条杆联接到卷帘板条。在锁定位置中，锁定条杆横向于通道基部延伸。锁定条杆具有缺口，缺口被断开壁覆盖，锁定条杆在锁定位置中断开壁与通道基部对齐。锁定条杆可以滑动地接收在套筒中，套筒定位在引导通道中以增加对
