Abstract

The utility model provides a writing board. The writing board comprises a writing board body and a frame arranged in the periphery of the writing board body. The frame is divided into an upper frame part, a lower frame part, a left frame part, and a right frame part, and the connection portions of the frame parts are fixed via corner braces. By the aid of the aforementioned technical scheme, the four frame parts of the writing board provided by the utility model can be fixedly arranged surrounding the periphery of the writing board body via the corner braces. The corner braces can be made of plastic materials and the frames can be fixed simply by being inserted into the corner braces. Compared with writing boards in the prior art, the writing board of the utility model is advantaged by being convenient to assembly and by being beautiful and elegant. In addition, the design of the corner braces enables the frame to be free of burr which may cause the risk of scratches to users.
