Resistance adjusting device for non-pull cord window blind
A resistance adjusting device for a non-pull cord window blind includes a base, a resistance adjusting seat, and a positioning pin. The base has a top hole, a pin hole, and a fixed shaft corresponding to the top hole. The resistance adjusting seat has a rotational shaft, and positioning holes and resistance adjusting rods arranged at intervals archedly relative to the rotational shaft. The resistance adjusting seat is rotatably sleeved onto the fixed shaft of the base by the rotational shaft, thereby able to adjust the friction resistance between the lift transmission cord and the resistance adjusting seat by one or a plurality of the resistance adjusting rods during rotation. The positioning pin is detachably disposed in the pin hole of the base and selectively inserted in one of the positioning holes of the resistance adjusting seat, to disable the resistance adjusting seat from rotating, thereby positioning it.
