[0030] Control components, there are two groups of them. Each group of control components includes a mounting groove 9, a fixed plate 10, a gear 11, a motor 12 and a rack 13. There are two fixed plates 10. The mounting groove 9 is opened on the surface of the inner frame 6. Both fixed plates 10 are fixedly connected to the inner wall of the outer frame 1. The gear 11 is rotatably connected to the two fixed plates 10 through a rotating shaft. The gear 11 meshes with the rack 13. The motor 12 is fixedly connected to the surface of one of the fixed plates 10, and the output end of the motor 12 is fixedly connected to one end of the rotating shaft.

[0031] In a specific embodiment of the present utility model, the outer frame 1 is installed inside the wall surface. The built-in frame 6 is slidably connected to the inside of the outer frame 1 through a sliding assembly. The control assembly is used to control the sliding of the built-in frame 6 inside the outer frame 1. When two electronic blackboard bodies 8 are installed in the built-in frame 6, the two electronic blackboard bodies 8 are installed in the slide rail 7 in a push-pull structure. When the electronic blackboard body 8 is used for a long time, it needs to be regularly maintained, or when the parts inside the electronic blackboard body 8 are damaged and need to be repaired, the control assembly operates. The motor 12 in the control assembly rotates. The output end of the motor 12 drives the rotating shaft to rotate, and the rotating shaft drives the gear 11 to rotate. The gear 11 meshes with the rack 13. By the rotation of the gear 11, the rack 13 is driven to move. The rack 13 is installed in the installation groove 9 opened on the surface of the built-in frame 6. The movement of the rack 13 drives the built-in frame 6 to move, facilitating the sliding of the built-in frame 6 into or out of the outer frame 1. When the built-in frame 6 slides out of the outer frame 1, it is convenient to maintain the electronic blackboard body 8. Compared with the traditional embedded electronic blackboard, the maintenance is more convenient.

[0032] Specifically, please refer to Figures 1-4 , each set of sliding assemblies includes a slide bar 4 and a slider 5. The slide bar 4 is fixedly connected to the surface of the U-shaped frame 3 and the inner wall of the outer frame 1. The slider 5 is fixedly connected to the surface of the built-in frame 6. The slider 5 is slidably connected to the circumferential surface of the slide bar 4.

Under normal use, the inner frame 6 is located inside the outer frame 1, and teaching information is displayed through the electronic blackboard main body 8. When the electronic blackboard main body 8 is damaged or needs to be maintained regularly, the control component operates. The output end of the motor 12 in the control component drives the rotating shaft to rotate, the rotating shaft drives the gear 11 to rotate, the gear 11 meshes with the rack 13. By the rotation of the gear 11, the rack 13 is driven to move. The rack 13 is installed in the installation groove 9 provided on the surface of the inner frame 6. The movement of the rack 13 drives the inner frame 6 to move, facilitating the inner frame 6 to slide into or out of the outer frame 1. When the inner frame 6 slides out of the outer frame 1, it is convenient to maintain the electronic blackboard main body 8. Compared with the traditional embedded electronic blackboard, the maintenance is more convenient.

[0044] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
