The back of the T-shaped seat 4 is provided with a mounting groove 16, and a rack 20 is fixed in the mounting groove 16. The gear 10 is meshed with the rack 20. The controller 5 is electrically connected to the plug 26 via a power cord. The controller 5 is electrically connected to the LED fluorescent board 7 and the motor 9. Two connecting plates 13 are threadedly mounted on the bottom end of the viewing board 1. The bottom end of the connecting plate 13 is fixed with a magnetic drawing board 3. The demonstration board The viewing board 1 equipped with an LED fluorescent board 7 can be used to place medical radioactive X-ray films. A gap is set between the viewing board 1 and the LED fluorescent board 7, which can be used to limit the clamping of radioactive X-ray film processing. It can be used to demonstrate and explain the content of medical radioactive X-ray films, and the difficult points and key knowledge of the explanation can be recorded on the magnetic drawing board 3 with a watercolor pen, thereby achieving the purpose of medical teaching. The T-shaped seat 4 can be easily moved to the vicinity of the power socket using the four rollers 23 rotatably installed on the bottom surface, and the power socket is plugged into the plug 26 to connect the controller 5 to the power supply. The controller 5 can be used to open and close the LED fluorescent board 7 and the motor 9. At the same time, the controller 5 can use the control key to adjust the brightness of the LED fluorescent board 7, and can be used to adjust the rotation direction of the motor 9. By adjusting the brightness, the observation effect of the radioactive X-ray film is better. The motor 9 transmission gear 10 rotates along the rack 20, and the motor 9 can drive the guide box 2 and the viewing board 1 to move vertically along the rack 20, so that the installation height of the viewing board 1 and the magnetic drawing board 3 can be adjusted, which is convenient for use and adjustment.

[0021] Reference Figure 1 and Figure 2 Both sides of the viewing board 1 are provided with heat dissipation grooves 6, which are used to dissipate heat from the controller 5. When the controller 5 is working, the power supply device and the circuit control board will generate a certain amount of heat, so the heat dissipation grooves 6 need to be used for heat dissipation.

The roller 23 is installed in the rotation groove 21 through an axis rotation. The anti-sliding block 25 is slidably installed in the rectangular groove 22. The T-shaped seat 4 can be easily displaced by rotating the four rollers 23. When it is moved to the destination, the two screws 24 are rotated and adjusted to make the corresponding anti-sliding block 25 slide along the rectangular groove 22 so that the anti-sliding block 25 contacts the ground, so that the T-shaped seat 4 is stably placed.

[0027] Working principle: The demonstration board can be used to place medical radiographic X-ray films through the viewing board 1 equipped with an LED fluorescent board 7. A gap is set between the viewing board 1 and the LED fluorescent board 7, which can be used to limit the clamping of radiographic X-ray film processing. It can be used to demonstrate and explain the content of medical radiographic X-ray films, and the difficult points and key knowledge of the explanation can be recorded on the magnetic drawing board 3 using a watercolor pen, thereby achieving the purpose of medical teaching. The T-shaped seat 4 can be conveniently moved to the vicinity of the power socket using the four rollers 23 rotatably installed on the bottom surface, and the power socket is plugged into the plug 26 to connect the controller 5 to the power supply. The controller 5 can be used to open and close the LED fluorescent board 7 and the motor 9. At the same time, the controller 5 can use the control key to adjust the brightness of the LED fluorescent board 7, and can be used to adjust the rotation direction of the motor 9. By adjusting the brightness, the observation effect of the radiographic X-ray film is better. The motor 9 transmission gear 10 rotates along the rack 20, and the motor 9 can drive the guide box 2 and the viewing board 1 to move vertically along the rack 20, so that the installation height of the viewing board 1 and the magnetic drawing board 3 can be adjusted, which is convenient for use and adjustment.
