Embodiment 1
[0020] A full-touch intelligent history teaching sound and shadow demonstration device with a teaching board, the full-touch intelligent history teaching sound and shadow demonstration device with a teaching board includes a base 8, a support frame 5 and a cross bar 1, wherein the support frame 5 Fixedly installed on the top surface of the base 8, the crossbar 1 is located above the base 8 and fixedly connected to the support frame 5, the base 8, the support frame 5, and the crossbar 1 form an "I"-shaped structure. A display device 2 is also connected to the crossbar 1, and the display panel of the display device 2 is divided into a button selection area 3 and an image display area 4, and several icons are arranged in the area of the button selection area 3. The display device 2 is also provided with a microprocessor, a key trigger module, a display card, a hard disk memory, a loudspeaker and a historical image display module, wherein the key trigger module, the display card,...
Embodiment 2
[0023] On the basis of Embodiment 1, the support frame 5 is a DNA rotating support frame 5, and the support frame 5 includes two spiral support plates 6 and several partitions 7, and the two spiral support plates 6 are oppositely arranged to form a spiral structure, a number of partitions 7 are stacked between two spiral support plates 6, both ends of each partition 7 are connected to the spiral support plate 6, and there is a certain distance between two adjacent partitions 7, so in An appliance placement grid 9 is formed between two adjacent partitions 7, and the appliance placement grid 9 is used for placing teaching aids. The distance between each group of adjacent two partitions 7 may not necessarily be the same, so the height of each utensil placement grid 9 will also be different.
Embodiment 3
[0025] On the basis of Embodiment 1 or Embodiment 2, several support rods 10 are arranged between the base 8 and the spiral support plate 6 , and the support rods 10 are evenly distributed around the circumference of the support frame 5 . In addition, the support rods 10 can be arranged in multiple layers that diverge outward around the axis of the support frame 5 . A number of support rods 10 are arranged between the base 8 and the spiral support plate 6, and the support rods 10 are uniformly distributed around the circumference of the support frame 5, thereby improving the strength of the spiral support plate 6 and improving the stability of the demonstration equipment.
