Abstract

The invention relates to the technical field of curtain installation, and discloses a telescopic device for a curtain rail. The telescopic device for the curtain rail comprises a sliding rail, whereinrollers are movably arranged in the sliding rail; the bottom of each roller is fixedly provided with a connecting ring; the bottom of each connecting ring is fixedly provided with a hook; the top ofeach roller is fixedly provided with a fixed column; and the peripheries of the fixing columns are sleeved with a telescopic frame. According to the telescopic device for the curtain rail, after the curtain is installed on the rollers, when the curtain is moved, the rollers drive the telescopic frame to stretch out by moving; the distances between the rollers are kept equal all the time when moving according to the lever principle, so that when the curtain is opened and closed, the folding distances formed by the curtain are equal, and the curtain is more attractive; meanwhile, the curtain canbe synchronously retracted, a situation that after a section of the curtain is pulled open, the next section begins to move can be avoided, and the curtain keeps attractive no matter how many of thesections the curtain are pulled open and the folds are uniform all the time.
