Title:
ROTARY SHUTTER
Document Type and Number:
WIPO Patent Application WO/2019/057132
Kind Code:
A1
Abstract:
A rotary shutter, comprising: a substrate (101), a fixing member (102), multiple blades (103) with rotating shafts (104), and a driving board (105). The fixing member (102) is disposed, in the form of a circular ring, on the substrate (101). The multiple blades (103) with rotating shafts are connected to the fixing member (102) by means of the rotating shafts (104) respectively. The blades (103) are located between the substrate (101) and the fixing member (102), and are arranged symmetrically about the center of rotation. The driving board (105) is sleeved on the fixing member (102) so that the blades (103) are located between the substrate (101) and the driving board (105). The driving board (105) is provided with multiple sliding grooves (108) that are arranged in the radial direction of the circular ring and slidably connected to guide rods (109) on the blades respectively. When being driven to rotate forwardly about the center of the circular ring, the driving board (105) can drive the blades (103) to synchronously rotate to a position where the arc edges of the blades (103) are brought close to each other, and when being driven to rotate reversely, the driving board (105) can drive the blades (103) to synchronously rotate to a position where the arc edges are separated from each other. The rotary shutter is simply structured and convenient to open and close.
