<p>A rotation stand is provided to rotate a display device smoothly by combining the display device and a supporter supported/rotated on a base, keep a desired rotation angle while moving a ball of the supporter along a stopping part formed to an upper part of the base, and prevent upward/downward movement of the display device by enabling a buffering part to adjust the upward/downward movement of the ball. A base(31) is put stably on the surface of a table. A supporter(41) is placed on the base, is combined with the display device(51), and is equipped with a penetrating hole(43). The ball(44) is installed to a bottom side of the supporter and is rolled on the base at an interval. A supporting bar(61) is fixed to the base and is inserted into the penetrating hole. A bearing(45) surrounds the supporting bar by being formed to the penetrating hole. A stopper(71) is installed on the base and restricts the movement of the ball by including upward/downward curves sequentially. The supporter includes the buffering part(81), such as a hydraulic cylinder, for buffering the ball upwardly and downwardly.</p> |
