Abstract

The invention belongs to the technical field of teaching appliances, in particular to an electronic whiteboard all-in-one terminal that is easy to maintain. For the existing electronic whiteboard all-in-one terminal, the installation structure is complicated and it is usually difficult to disassemble, so it is not convenient to quickly disassemble when a fault occurs. In order to solve the problem of maintenance, the following solution is proposed, which includes an electronic whiteboard body and a bracket, two fixing plates are fixedly installed on the top of the bracket, and screw holes are opened on the two fixing plates, and the inner wall of the bracket is movable. Two pulleys are installed, second through holes are opened on the two pulleys, and insertion rods are movably installed in the two second through holes. In the present invention, the fixing methods of each structure are both simple and firm, so the electronic whiteboard When the body is used and taught, the teaching quality will not be affected, and when the electronic whiteboard body needs to be repaired, each structure can also be quickly disassembled, thereby facilitating maintenance.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to an electronic whiteboard all-in-one terminal which is convenient for maintenance. Background technique [0002] The electronic whiteboard is a kind of intelligent teaching tool. The electronic whiteboard can simulate the white background of the whiteboard, and then project the image through the projector, thus replacing the way that teachers use blackboard writing in class. Teaching through the electronic whiteboard can prepare files on the computer in advance. , you can use a projector to project during class. [0003] However, the existing electronic whiteboard all-in-one terminal has a complex installation structure and is usually difficult to disassemble. Therefore, when a fault occurs, it is not convenient to quickly disassemble for maintenance. Therefore, a new type of electronic whiteboard is needed to solve this problem. Contents of the invention [0004] The pu...
