[0027] According to this specific implementation, the display board 101 is used to display the mental health education content for college students.

[0028] Among them, the base 103 is located below the display board 101; the multiple wheel frames 104 are rotatably connected to the base 103 and are respectively located at the bottom of the base 103; the multiple rollers 105 are rotatably connected to the multiple wheel frames 104 and are respectively located at the inner sides of the multiple wheel frames 104; the two locking screws 106 are respectively threadedly connected to the base 103 and pass through the base 103 respectively; the two abutment plates 107 are respectively rotatably connected to the two locking screws 106 and are respectively located at the bottom of the two locking screws 106; the lifting mechanism 108 is fixedly connected to the base 103 and is located at the top of the base 103; the mounting platform 109 is fixedly connected to the lifting mechanism 108 and is located at the top of the lifting mechanism 108; the rotating shaft 110 is rotatably connected to the mounting platform 109, fixedly connected to the display board 101, and located at the bottom of the display board 101. The wheel frame 104 is rotatably mounted on the bottom of the base 103, so the roller 105 can roll in any direction, so the base 103 can move in any direction. After the base 103 is moved to the required position, the two locking screws 106 are screwed to drive the two abutment plates 107 to abut against the ground to fix the base 103. The lifting mechanism 108 is used to adjust the height of the mounting platform 109, and the display board 101 is rotatably mounted on the mounting platform 109 through the rotating shaft 110. Therefore, the lifting mechanism 108 can adjust the height of the display board 101, and the display board 101 can be rotated to adjust the display angle. Due to the use of the rotatably mounted wheel frame 104, the roller 105 can roll in any direction, so that it can be easily turned and moved in any direction.

[0029] Secondly, the two knobs 111 are respectively fixedly connected to the two locking screws 106 and are respectively located at the tops of the two locking screws 106. The knobs 111 are used to conveniently turn the locking screws 106.

[0030] At the same time, the weight shaft 112 is rotatably connected to the mounting platform 109 and is located inside the mounting platform 109; the counterweight plate 113 is fixedly connected to the weight shaft 112 and sleeved on the weight shaft 112; the large gear 114 is fixedly connected to the rotating shaft 110 and sleeved on the rotating shaft 110; the small gear 115 is fixedly connected to the weight shaft 112 and meshes with the large gear 114. When the display board 101 is rotated, the rotating shaft 110 is driven to rotate, the rotating shaft 110 drives the large gear 114 to rotate, the large gear 114 drives the small gear 115 to rotate, the small gear 115 drives the weight shaft 112 to rotate, and the weight shaft 112 drives the counterweight plate 113 to rotate. The large gear 114 drives the small gear 115 to be a laborious lever, which cooperates with the counterweight plate 113, so that the display board 101 will not be easily rotated by force after rotation adjustment, which is used to stabilize the angular position of the display board 101.

[0031] In addition, the motor 116 is fixedly connected to the base 103 and is located at the top of the base 103; the threaded barrel 117 is fixedly connected to the mounting platform 109 and is located at the bottom of the mounting platform 109; the driving screw 118 is fixedly connected to the output end of the motor 116, and is threadedly connected to the threaded barrel 117 and is located inside the threaded barrel 117; the two sleeves 119 are respectively fixedly connected to the base 103 and are respectively located at the top of the base 103; the two sliding rods 120 are respectively slidably connected to the two sleeves 119, and are respectively fixedly connected to the mounting platform 109 and are respectively located at the bottom of the mounting platform 109. The sleeves 119 and the sliding rods 120 form a telescopic rod to support the mounting platform 109, and the motor 116 drives the driving screw 118 to rotate, and the driving screw 118 drives the threaded barrel 117 to rise and fall, thereby driving the mounting platform 109 to rise and fall, and synchronously, the sliding rod 120 slides inside the sleeves 119.

[0032] In the teaching demonstration board described in this embodiment, the wheel frame 104 is rotatably mounted at the bottom of the base 103, so the roller 105 can roll in any direction, so the base 103 can move in any direction. After the base 103 is moved to the required position, the two locking screws 106 are screwed to drive the two abutment plates 107 to abut against the ground to fix the base 103. The lifting mechanism 108 is used to adjust the height of the mounting platform 109, and the display board 101 is rotatably mounted on the mounting platform 109 through the rotating shaft 110. Therefore, the lifting mechanism 108 can adjust the height of the display board 101, and the display board 101 can be rotated to adjust the display angle. Due to the use of the rotatably mounted wheel frame 104, the roller 105 can roll in any direction, so that it can be easily turned and moved in any direction. When moving, the two abutment plates 107 need to be moved away from the ground.
