Roller blind

Abstract

Provided in the present application is a roller blind, comprising a mounting bracket, a roller tube, a fabric and an energy storage device, wherein one end of the fabric is fixedly connected to the roller tube. The energy storage device comprises a rotating frame, a fixed shaft and a plurality of coil springs, wherein the fixed shaft is fixed to the mounting bracket; the rotating frame is sleeved on the fixed shaft, is fixed to the roller tube, and can rotate relative to the fixed shaft along with the roller tube; the rotating frame comprises a plurality of sub-supports, the plurality of sub-supports are arranged in sequence in the axial direction of the fixed shaft, and every two adjacent sub-supports are detachably connected to each other; each sub-support is provided with a shaft hole, and the fixed shaft passes through the shaft hole of each sub-support; the coil springs are sleeved outside the fixed shaft, and each coil spring is arranged between two adjacent sub-supports; and the inner ends of the coil springs are connected to the fixed shaft, and the outer ends of the coil springs are connected to the sub-supports. By designing the rotating frame of the roller blind as a detachable structure, the versatility of the rotating frame is improved, and the design and manufacturing costs of the rotating frame are reduced.
