Damping positioner

摘要

A damping positioner is installed in a headrail track of an automatic roll-up blind and works with an automatic winding mechanism of the roll-up blind. The damping positioner includes a positioner that is disposed in the headrail track as well as a damper that is connected at an end of the positioner and is able to rotate freely. An interior of the damper is provided with a spring assembly, a gear assembly and a brake set. The winding speed of the roll-up blind is controlled by the gear assembly and the brake set, such that the roll-up blind can be rolled up moderately. Moreover, the damping positioner is installed in the headrail track without being exposed; therefore, the integrity of appearance of the roll-up blind can be reserved.
