Abstract

The invention relates to the technical field of computer auxiliary equipment, and discloses a computer-aided switching type coverage teaching blackboard. The computer-assisted switching type coverageteaching blackboard comprises a lifting support. A computer main machine is fixedly connected to the top of the lifting support. A top first chain wheel, a top second chain wheel, a bottom first chainwheel, a bottom second chain wheel and a main rotating shaft are rotationally connected into the lifting support. The lifting support is fixedly connected with a fixed blackboard. According to the computer-assisted switching type coverage teaching blackboard, a switching frame is driven to move through a switching cam, the switching frame drives a left driven wheel to rotate, the left driven wheel drives a transmission rack to move, the transmission rack drives a main rotating wheel to rotate, the main rotating wheel drives the top second chain wheel and the bottom first chain wheel to rotate, the top second chain wheel and the bottom first chain wheel drive the transmission chain to rotate, the transmission chain drives a movable blackboard to move, and then the effect of free switchingof double blackboards is achieved through cooperative use of a power wheel and other mechanisms.

Description

technical field [0001] The invention relates to the technical field of computer-aided equipment, in particular to a computer-aided switching overlay teaching blackboard. Background technique [0002] With the development of society and the continuous advancement of science and technology, multimedia classrooms have been vigorously developed. Multimedia classrooms are lively and interactive, which greatly improves teaching efficiency. Although multimedia teaching has many advantages, the traditional blackboard teaching is multimedia teaching. It cannot be replaced. Multimedia teaching is mostly used to supplement blackboard writing, animation demonstration, etc., so the actual blackboard writing bears more content. Due to the blackboard area is certain, when explaining various knowledge, blackboard writing is often erased, so that It will cause students to not be able to connect with each other before and after the knowledge, resulting in a reduction in the effect of class. ...
