The rolling wheel adjustable positioning mechanism comprises fixed supports, sliding supports and rolling wheels. The rolling wheels are arranged on the corresponding sliding supports in a rolling mode, and the sliding supports are arranged on the corresponding fixed supports in a sliding mode. The fixed supports are provided with sliding blocks, swing rods and adjusting elements. The sliding blocks are arranged on the corresponding fixed supports in a sliding mode. One ends of the swing rods are connected with the corresponding sliding blocks in a swinging mode, and the other ends of the swing rods are connected with the corresponding sliding supports in a swinging mode. The adjusting elements are positioned on the fixed supports in a rotating mode and are further connected with the sliding blocks in a driving mode. The sliding supports are arranged on the corresponding fixed supports in a sliding mode through matching of the sliding blocks, the swing rods and the adjusting elements. The outer diameter size of each rolling wheel is greater than the height size of the corresponding sliding support and fixed support. Due to the structural improvement, the rolling wheel adjustable positioning mechanism has the characteristics of being simple and reasonable in structure, reliable in performance, fast and convenient to adjust, accurate in positioning, high in bearing capacity, small in size, convenient to dismount and mount, stable, smooth, soft, mute and free of shaking in the opening and closing process, small in applied force and the like; and the practicability is high.
