Abstract

The invention discloses a college Chinese teaching demonstration board which comprises a main body. A motor switch is arranged on the side surface of the main body. The input end of the motor switch is electrically connected with the output end of an external power source, the side surface of the main body is provided with a motor, the input end of the motor is electrically connected with the output end of the motor switch, the side surface of the main body is provided with a first sliding groove, an output shaft of the motor penetrates into the first sliding groove and is connected with a driving screw rod through a coupler, and the driving screw rod is in threaded connection with a screw hole formed in the side surface of a sliding block. According to the college Chinese teaching demonstration board, manual operation of teachers or students is replaced with electric wiping, working efficiency is improved, the phenomenon that time is wasted since the demonstration board is wiped in aclass is avoided, the teaching effect is improved, the motor can drive the sliding block through the screw rod to move, the sliding block and an installation plate are connected through a bolt, the installation plate can be conveniently detached, a board eraser can be convenient to replace, and the board eraser can be cleaned through a cleaning water pipe.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a university Chinese teaching demonstration board. Background technique [0002] College Chinese is a basic subject in our country's college education. In the teaching process of college Chinese, it is often necessary to use a demonstration board for a large number of writing on the blackboard. Most of the existing college Chinese teaching demonstration boards cannot automatically erase the words on the demonstration board, and need to be manually erased by teachers or students. The work efficiency is low, and erasing during class will waste time and affect the teaching effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a university Chinese teaching demonstration board, which replaces the manual operation of teachers or students by electric erasing, improves work efficienc...
