Resistance regulating device for rope-free curtain

A resistance regulating device for a rope-free curtain, comprising:

• a cavity arranged on a frame body for fixing the curtain, wherein a side surface of the cavity is provided with a transverse rope hole, a bottom surface thereof is provided with a vertical rope hole, and the cavity is further internally provided with a regulating column groove vertically formed between a retarding unit and the transverse rope hole, one end of a rope body passes through the transverse rope hole and the vertical rope hole in sequence and is connected to the curtain and the other end of the rope body is connected to a retrieval device;
• and
• the retarding unit rotatably arranged in the cavity and configured to rotate following a movement of the rope body when the rope body moves outwards from the transverse rope hole to reduce resistance applied to the rope body, and configured to rotate following a movement of the rope body when the rope body moves outwards from the vertical rope hole to increase resistance applied to the rope body;
• and
• the cavity is further internally provided with a stop rod configured to resist the retarding unit;
• and
• a resistance regulating unit, comprising a regulating column arranged in the regulating column groove and a regulating bolt, wherein the regulating bolt is configured to drive the regulating column to move along the regulating column groove to adjust an angle of the rope body between the transverse rope hole and the retarding unit, thereby regulating resistance of the rope body.
