Abstract

The invention relates to the technical field of multimedia equipment, and discloses a whiteboard double-sided shading device of multimedia equipment. The device comprises a bottom board, the upper end of the bottom board is slidably connected with a board body, a moving groove is formed in the bottom board, a heat dissipation device is fixedly installed at the position, on the end face of the outer end of a driving device, of the upper end of the moving groove, the driving device is slidably connected to the upper end of the moving groove, a driving wheel is rotatably connected to the upper end of the driving device, and lifting plates are fixedly installed at the left end and the right end of the bottom board. According to the whiteboard double-sided shading device of the multimedia equipment, through rotation of a power wheel, under the action of the lifting plates, the power wheel drives sliding boards to move upwards in the bottom board, then the sliding boards can drive the board body to move upwards on the bottom board, and the effect of lifting the height is achieved; and when the board body is fixed, the stabilizing effect of the board body during fixing can be effectively improved through cooperation with the functions of limiting rods and limiting grooves in clamped connection rods.

Description

technical field [0001] The invention relates to the technical field of multimedia equipment, in particular to a double-sided shading device for a whiteboard of multimedia equipment. Background technique [0002] Multimedia equipment includes: computers, boards, projectors and other equipment. The board is a tool for teachers to mark and record important knowledge parts. By writing the content on the board, and then showing it to the students in the class, but if you encounter In the case of sunlight reflection, the board body will reflect light, causing the students on the left and right sides to not be able to clearly see the content on the board body. Moreover, the height of the current board body is generally fixed. If the teacher is taller, it is not easy to It is convenient to write on the board body. [0003] In response to the above-mentioned problems, there is an urgent need for a device that can adjust the height of the board, which is suitable for teachers of diff...
