Abstract:
The present invention relates to a blade damper comprising: a frame (100); a plurality of shafts (200), installed in parallel inside the frame (100) and spaced from each other at a certain interval, for opening and closing an internal space of the frame (100); and blades (300) coupled to the shafts (200), wherein the frame is formed in a quadrilateral frame shape of which the upper portion and the lower portion are perforated, and wherein the plurality of shafts (200) are disposed in a row inside the frame (100) and are coupled to the blades (300) of which the horizontal cross section is in a rectangular shape. Thus, when rotating the shafts (200), the blades (300) are rotated together, thereby opening and closing the internal space of the frame (100). The present invention enhances air tightness by structurally modifying an end of a blade, and thus has remarkable effects of minimizing damage that may occur and easily opening and closing the blade even with small force
