Abstract
The invention provides a white board with three sides capable of being turned. The white board comprises a support, a power mechanism and a plurality of triangular prism white board strips. Each triangular prism white board strip comprises three white board bodies and two or more regular-triangle-shaped supporting plates, wherein the regular-triangle-shaped supporting plates are arranged in parallel and located side by side, the white board bodies are arranged on the three edges of each regular-triangle-shaped supporting plate, and therefore the triangular prism structure is formed. A rotating shaft is arranged on the central axis of each triangular prism white board strip, wherein the rotating shaft extends out of the two ends of the triangular prism white board strip and is installed on the support. The triangular prism white board strips are arranged on the support in sequence and constitute a plane. The rotating shafts are connected with the power mechanism through worm and gear structures. The power mechanism drives the triangular prism white board strips to rotate at the same time through the worm and gear structures, so that the three sides of each triangular prism white board strip are turned. According to the white board with the three sides capable of being turned, under the condition that the area is kept the same, the written content is three times that of an existing white board, and the sizes of written characters are standardized, and written content is flat and straight.
