Rubber wheel mechanism of ceiling curtain

Rubber wheel mechanism of ceiling curtain, including slide bar, guide rail, the tip of slide bar install set in the guide rail and with the inner wall that the opening is relative of the guide rail first pulley of mode complex with rolling friction, the end fixing of slide bar has an adapting unit, first pulley pin joint on this adapting unit, this adapting unit go up the pin joint have one with at least one lateral wall of the opening of guide rail mode complex second pulley with rolling friction, the rotation axis of second pulley and the extending direction of slide bar are unanimously. The utility model discloses a rubber wheel mechanism of ceiling curtain, the tip of slide bar is installed and is set in the guide rail and the mode complex first pulley of the inner wall relative with the guide rail opening with rolling friction to and one with at least one lateral wall of guide rail opening mode complex second pulley with rolling friction, reduce the tip of slide bar and the friction between the guide rail, make the operation of slide bar more smooth and easy, also reduce the noise of operation in -process simultaneously, and simple structure.
