A rotatable link mechanism for a wall-mounting bracket with two arms comprises a wall-fixing bracket (1), two rotating links (2) and a load-fixing bracket (3). The two rotating links (2) include front arms (21) and back arms (22), which are coupled with each other via the pin shafts (4) with dampers. The two front arms (21) are connected to the load-fixing bracket (3) via the pin shafts with dampers. The two back arms (22) are connected to the wall-fixing bracket (1) via the pin shafts (4) with dampers. A front arm extending limited protuberance (211) is provided on the end of front arm connected to the load-fixing bracket. A back arm extending limited protuberance (221) is provided on the end of back arm connected to the wall-fixing bracket. There are distances between two fixing holes (11,12) on the wall-fixing bracket and between two fixing holes (31,32) on the load-fixing bracket. The internal distance (L3) of two posts of the wall-fixing bracket is larger than the width (L4) of the load-fixing bracket. The distance (L6) between two connecting holes of the front arm is larger than that (L5) of the back arm. The rotatable link mechanism has high load-bearing ability and good horizontal stability. The load can be provided close to the wall and its rotating angle is limited. |
