College music education score writing presentation device

Abstract

The invention discloses a college music education score writing presentation device. The device comprises a blackboard; the upper portion and the lower portion of the back side of the blackboard are fixedly connected with a wall through fixing boards which are transversely arranged; a plurality of first sliding rails are fixedly installed on the outer sides of the fixing boards correspondingly; transverse beams are disposed on the upper portions of the first sliding rails; a guiding block is fixedly installed at the lower end of a first vertical bar; the bottom of a fixing bar is fixedly connected to the lower end surface of the interior of a bottom case; the lower portion of a top case is fixedly connected with the upper portion of the bottom case through a vertical shell; a plurality ofannular blackboard erasers are uniformly and fixedly installed in the middle of a second vertical bar and on a third vertical bar; and first springs exert force, which is towards the wall, on the transverse beams, then the annular blackboard erasers are tightly attached to the blackboard, and thus the blackboard can be fast and efficiently cleaned by erasing. By means of the college music education score writing presentation device, the workload of teachers is relieved, the labor intensity of the teachers is lowered, the shell is in a C shape, thus dust spreading can be effectively inhibited,the teachers are prevented from inhaling the dust, and the physical health of the teachers is guaranteed.
