Problems solved by technology
[0004] In order to meet different usage requirements, it is sometimes necessary to further adjust the resistance provided by the resistance device to the lifting transmission rope. However, in the aforementioned prior art, the user must disassemble the entire rope reel to adjust the resistance device. Reassemble the rope reel after it is positioned. In addition to being very inconvenient in operation, the rope reel may affect the assembly accuracy of the internal components after repeated disassembly and assembly.

The present invention provides a resistance adjustment device for curtains without exposed drawstrings, which includes a base, a resistance adjustment seat and a control pin, the base has a first positioning part and a fixed shaft, and the resistance adjustment seat has a The transmission shaft is sleeved on the fixed shaft of the base by the transmission shaft. The control pin has a drive shaft and is sleeved on the fixed shaft of the base by the drive shaft. The drive shaft has a second positioning part and a driving part. The second positioning part of the drive shaft of the control pin is clamped to the first positioning part of the base, and the control pin cannot rotate. At this time, the resistance of the lifting transmission rope cannot be adjusted. When the second positioning part of the drive shaft of the control pin breaks away from the base The first positioning part of the first positioning part, and the driving part of the driving shaft of the control pin is clamped to the transmission shaft of the resistance adjustment seat, and the control pin can drive the resistance adjustment seat to adjust the resistance of the lifting transmission rope.
Description
[0001] This application is a divisional application, the application number of the parent case: 201711274474.5, the application date: December 06, 2017, and the name: a resistance adjustment device for curtains without exposed drawstrings. technical field [0002] The present invention relates to a non-exposed drawstring curtain, in particular to a resistance adjustment device for a non-exposed drawstring curtain. Background technique [0003] As for a general non-exposed drawstring curtain, when the lower beam is pulled down, the lifting transmission rope set on the blade will be stretched outward by the lower beam and gradually come out from the rope reel until the blade is fully unfolded; on the contrary, when the When the lower beam is pushed up, the upward pushing force on the lower beam will offset the weight of the lower beam and all blades, so that the rope reel can smoothly retract the lifting transmission rope, and then the blades can be retracted smoothly. However...
