[0015] 1. This adjustable museum digital display panel, through the setting of a drive component, starts a servo motor that drives the second bevel gear to rotate via the output shaft. The cooperation between the second bevel gear and the first bevel gear causes the threaded rod to rotate, causing the upper and lower threaded blocks to move relative to each other. Then, the cooperation between the upper and lower threaded blocks, the X-shaped connecting rod, and the upper and lower sliders causes the L-shaped connecting frame to move the seat cushion out, thus providing researchers with a place to rest and avoiding knee injuries caused by prolonged standing. At the same time, compared with traditional chairs, it can prevent the chair from being removed and moved, thus improving the practicality of the device.

[0016] 2. This adjustable museum digital display panel features an electric push rod and a mini electric push rod. Activating the electric push rod moves the sliding base and the main body of the digital display panel, adjusting the viewing distance.

[0025] In summary, this adjustable museum digital display panel, through the setting of drive component 5, starts the servo motor 55 to drive the second bevel gear 56 to rotate via the output shaft. The cooperation between the second bevel gear 56 and the first bevel gear 54 causes the threaded rod 53 to rotate, causing the upper and lower threaded blocks 57 to move relative to each other. Then, the cooperation between the upper and lower threaded blocks 57, the X-shaped connecting rod 59, and the upper and lower sliders 58 causes the L-shaped connecting frame 3 to move the seat cushion 4 out, thereby providing researchers with a place to rest and avoiding knee injuries caused by prolonged standing. At the same time, compared with traditional chairs, it can prevent the chair from being removed and moved, thus avoiding disruption to rest. This invention enhances the practicality of the device. By setting up an electric push rod 10 and a miniature electric push rod 9, the electric push rod 10 can be activated to move the sliding seat 6 and the main body of the digital exhibition board 8, adjusting the viewing distance. The miniature electric push rod 9 can be used to adjust the viewing angle of the main body of the digital exhibition board 8, adapting to different staff members. This further improves the practicality of the device and solves the problem that existing museum digital exhibition boards can only play a simple promotional role and cannot provide a rest function for researchers. Academic researchers often stand in front of the digital exhibition board to view it, and standing for a long time can cause damage to the staff's knees.
