Abstract

The invention relates to a blackboard, in particular to a cleaning type blackboard for teaching. According to the cleaning type blackboard for teaching, the blackboard can be cleanly and wholesomely wiped. The cleaning type blackboard for teaching comprises a fixed box and the like. An opening is formed in the front wall of the fixed box. Lower leaking holes are evenly formed in the bottom of the fixed box. A first blackboard is arranged on the inner top of the fixed box. A rotating moving device is arranged at the inner lower part of the fixed box. The rotating moving device is located on the lower portion of the blackboard. Fixing devices are connected with the left end and the right end of the rotating moving device. The top of the fixing device is connected with a supporting rod. A small hole is formed in the supporting rod. A blackboard eraser is arranged at the top end of the supporting rod. By means of the cleaning type blackboard for teaching, the effects of clean wiping and convenient cleaning are achieved, the first blackboard is wiped only needing to rotate a rotating rod, words on the blackboard can be quickly wiped off, and the fact that a user wipes the first blackboard more conveniently and fast is achieved.
