Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, in particular to a digital educational interactive device. Background Art

[0002] The touch screen is used for multimedia playback, carrying pictures and text information and magnifying them for students to watch and learn. It is also an educational interactive device that combines learning with entertainment. The current touch screen requires a bracket when in use. The installation method of the current touch screen bracket is complicated, and the touch screen needs to be disassembled and assembled for maintenance, which consumes a lot of time and has low practicality.

[0003] The patent with the publication number CN216479732U discloses a multimedia digital educational interactive device, including a base, the upper side wall of the base is connected with an exhibition board through a lifting mechanism, the side walls of the exhibition board are fixedly connected with a fixed plate, two guide rods are symmetrically fixedly connected between the two fixed plates, the outer walls of the two guide rods are fixedly sleeved with two clamping plates, the upper side wall of the exhibition board is fixedly connected with a mounting block, the outer wall of the mounting block is fixedly connected with a motor, the output shaft end of the motor passes through the outer wall of the mounting block and is fixedly connected with a gear, and the side walls of the two clamping plates opposite to each other are fixedly connected with a fixed rod. The utility model realizes the reverse movement of the two clamping plates through the meshing of the gear and the two saw teeth, thereby facilitating the installation and disassembly of the touch screen, has a simple structure and high practicality, and at the same time, through the extension and return of the hydraulic cylinder driving end, the effect of adjusting the height of the touch screen is achieved.

[0004] In the specific use of the above-mentioned prior art, the gear is driven to rotate by a motor, and then the serrations on the two fixing rods that mesh with them are used to move the two fixing rods toward each other, thereby driving the two clamping plates to move toward each other to complete the clamping and fixing of the touch screen, and then the motor is started to reverse, so that the two clamping plates move away from each other and detach from the touch screen, thereby facilitating the installation and disassembly of the touch screen. However, when the two clamping plates clamp and fix the touch screen, the touch screen is in a suspended state. After long-term use, the touch screen is likely to shift downward or even fall off. Therefore, the above-mentioned prior art has safety risks in actual use. In view of this, we propose a digital educational interactive device. Utility Model Content
