Slide rail anti-falling structure for electric curtain

The utility model relates to the technical field of electric curtains, in particular to a sliding rail anti-falling structure for an electric curtain, which comprises a shell, mounting mechanisms are arranged at two ends of the shell, a mounting cavity is formed in the shell, and an anti-falling transmission component is arranged on the surface of the shell; the anti-disengaging transmission assembly comprises a positive and negative tooth screw rotationally connected to the inner wall of the mounting cavity. When the sliding rail anti-disengaging structure for the electric curtain is used, the servo motor is used for driving the positive and negative tooth screw rod to rotate, then the two movable sliding blocks are driven to move, the curtain is opened and closed, when the curtain is directly dragged by external force, the iron sheet and the magnet are disengaged, and the sliding ring slides along the limiting sliding rod under the external force, so that the curtain is opened and closed.
