Title:
HAND-SUPPORT ZEBRA BLIND DRIVEN BY SPRING ROD
Document Type and Number:
WIPO Patent Application WO/2022/166995
Kind Code:
A1
Abstract:
Disclosed in the utility model is a hand-support zebra blind driven by a spring rod, the zebra blind comprising a left bracket and a right bracket which are arranged opposite each other. A roller is arranged between the left bracket and the right bracket; blind fabric is wound around an outer side of the roller; one of the left bracket and the right bracket is provided with the spring rod; the spring rod is inserted into the roller, is connected to an inner wall of the roller, and can drive the roller to rotate so as to roll up the blind fabric; the other one of the left bracket and the right bracket is provided with a tail plug; the tail plug is inserted into the roller, is connected to the inner wall of the roller, and generates resistance for preventing the roller from rotating; and the direction of the resistance is opposite the direction of a driving force generated by the spring rod. A drive used for driving the roller to rotate is arranged on the spring rod, and both the spring rod and the tail plug can extend into the roller, thereby preventing the thickness of the bracket from being configured to be too large, such that the problem of a gap between the blind fabric and a wall being too large is solved.
