The first gear drives the first rack in the strip-shaped groove to move upward, thereby driving the protective plate to slide upward on the front wall of the protective frame. At the same time, the connecting groove on the protective plate slides on the T-shaped rod. When the connecting groove moves upward to the maximum limit, the protective plate is located above the second gear. At this time, the display is shown outside. Then turn off the first motor, so that the protective plate only occupies the upper space, which can also avoid the influence of the protection device on the flow of people and reduce the risk of collision between the protection device and people.

[0014] 2. After the protective plate moves upward to the maximum position in the present utility model, start the second motor to drive the screw rod to rotate. The screw rod makes the driving block drive the second rack to move horizontally. The second rack drives the second gear to make the rotating shaft rotate on the protective frame. The rotating shaft drives the connecting frame to rotate through the connecting block. The connecting frame drives the protective plate to rotate through the connection between the T-shaped rod and the connecting groove. When the driving block moves to the maximum limit, the rotating shaft rotates 180 degrees, and the protective plate also rotates 180 degrees. Then turn off the second motor; then start the first motor to make the protective plate slide downward on the rear wall of the protective frame. When it moves downward to the maximum limit, turn off the first motor. At this time, the protective plate is located at the rear side of the protective frame; this solves the problem that the protection device occupies a large space after being opened and avoids waste of space.

A second gear 12 engaged with a second rack 13 is fixed at the lower end of the rotating shaft 11. A support frame 16 is fixed on the top surface of the rear end of the protective frame 2. A lead screw 15 fixed to a second motor 17 is horizontally rotatably provided inside the support frame 16. The cross-section of the support frame 16 is U-shaped. The two ends of the lead screw 15 are respectively rotatably connected to the left and right side plates of the support frame 16. The right end of the lead screw 15 passes through the support frame 16 and is fixed to the output end of the second motor 17. The second motor 17 is fixed to the top surface of the protective frame 2. The lead screw 15 is provided with a driving block 14 which is fixed to the rear wall of the second rack 13. The driving block 14 is located between the support frames 16. The driving block 14 is slidably connected to the inner wall of the support frame 16, which can enable the driving block 14 to move stably. When the driving block 14 moves to the maximum position, the second rack 13 causes the second gear 12 to rotate 180 degrees. The driving block 14 is fixed to the center of the rear wall of the second rack 13. A connecting frame 9 is fixed to the upper end of the rotating shaft 11 through a connecting block 10. A first motor 8 is fixed to the side wall of the connecting frame 9. A connecting shaft 7 is horizontally fixed to the output end of the first motor 8. A first gear 6 engaged with a first rack 5 is fixed to the outer wall of the connecting shaft 7. The cross-section of the connecting frame 9 is C-shaped. The two ends of the connecting shaft 7 are respectively rotatably connected to the two side plates of the connecting frame 9. The first gear 6 is located between the connecting frames 9. The connecting frame 9 is located above the second gear 12. A protective plate 3 is provided on one side of the protective frame 2. The opening of the protective plate 3 can expose the display 19 outside. When the display 19 is not in use, the position of the protective plate 3 is adjusted to protect the display 19. The protective plate 3 is slidably connected to the protective frame 2. The height of the protective plate 3 is higher than that of the protective frame 2, which can ensure that when the first gear 6 drives the first rack 5 to move upward, the protective plate 3 can be completely above the protective frame 2. The length of the protective plate 3 is equal to the length of the protective frame 2. A strip-shaped groove 4 fixed to the first rack 5 is vertically opened on the side of the protective plate 3 close to the first gear 6.
