Abstract

An electric curtain rod. A control switch (1-2) controls rotation of a motor (1-1). The motor (1-1) drives rotation of a first screw rod (7). The rotating first screw rod (7) rotates a first gear nut (2-4) to drive movement of a second gear nut (2-5), so as to simultaneously cause a second screw rod (8), fittingly connected to the second gear nut (2-5), to rotate in the opposite direction. In this way, a first movable block (3) and a second movable block (4), that may only slide along a rail slot, simultaneously move in opposite directions. The rotation direction of the motor (1-1) determines the directions in which the first movable block (3) and the second movable block (4) move, such that changing the rotation direction of the motor (1-1) can cause the first movable block (3) and the second movable block (4) to approach or recede from each other, thereby driving sliding of a curtain hanging ring (18) to achieve opening and closing of curtains. The electric curtain rod operates stably, has a long lifespan, and is able to achieve automatic opening and closing of curtains.
