The invention relates to a pull-rope-free double-layer roller shutter. The double-layer roller shutter mainly solves the problems that a positioning mechanism needs to be unlocked for rolling when a curtain fabric of an existing double-layer roller shutter without a pull rope is rolled, the mechanism is complex, and the curtain fabric is inconvenient to roll. The device is characterized in that a retractor (5) is installed at one end of the winding drum (4), a damping compensator (6) is installed at the other end of the winding drum (4), and the damping compensator (6) comprises a connecting sleeve (7), an expansion sleeve (8), an expansion block (9) and a screw rod (10); and the connecting sleeve (7) can rotate relative to the expansion sleeve (8). The difference value between the rolling acting force of the rolling device and the downward gravity of the bottom frame is compensated through the friction resistance of the damping compensator, so that when the bottom frame is located at any position, the rolling acting force borne by the curtain cloth and the sinking gravity can be balanced, and the purpose that the curtain cloth can be stopped when being pulled down or rolled up to any position is achieved; the curtain has the advantages of being simple in structure and convenient to roll.
本发明涉及一种无拉绳双层卷帘。主要解决了现有的无拉绳双层卷帘在收卷帘布时需要先将定位机构解锁才能收卷，机构复杂、帘布收卷不方便的问题。其特征在于：所述卷筒(4)的一端安装有卷收器(5)，所述卷筒(4)的另一端安装有阻尼补偿器(6)，所述阻尼补偿器(6)包括连接套(7)、涨套(8)、涨块(9)及螺杆(10)；所述连接套(7)能够相对涨套(8)转动。本发明利用阻尼补偿器的摩擦阻力对卷收器的卷收作用力与底框向下的重力之间的差值进行补偿，使底框处于任意位置时帘布受到的卷收作用力与下沉重力之间都能平衡，达到帘布下拉或卷起到任意位置都能停止的目的，具有结构简单、帘布收卷方便的特点。
