Multiple slots 34 are provided on the side of each column 31. A third slider 37 is fixedly connected to the rear side of the second slider 36. A spring 38 is provided on the outer side of the limiting rod 35. The front side of the first slider 32 is located on the rear side of the electronic display screen 12. One side of the spring 38 is fixedly connected to the right side of the second slider 36. The other side of each spring 38 is fixedly connected to the inside of the connecting block 33. Multiple electric telescopic rods 6 are provided at the bottom of the base plate 1. A pad 7 is provided at the extended end of each electric telescopic rod 6. Multiple wheels 8 are provided at the bottom of the base plate 1. A DC motor 5 is provided at the center inside the base plate 1. A threaded rod 9 is provided at the output shaft of the DC motor 5. A support plate 2 is provided at the top of the base plate 1. A sixth slider 10 is provided outside the threaded rod 9. The front side of the sixth slider 10 is fixedly connected to the rear side of the support plate 11.

[0027] The overall effect of Embodiment 1 is as follows: the relevant components can improve the viewing comfort of the traditional height-adjustable electronic display screen through mechanical transmission. The function of setting the third slider 37 is to limit the sliding of the second slider 36. The function of setting multiple slots 34 is to achieve more specific angle adjustment. The function of setting the spring 38 as a strong spring is to stabilize the position of the electronic display screen 12. This mechanical transmission method uses the adjustment mechanism to adjust the angle of the screen, preventing eye fatigue, neck and back pain.

[0028] Example 2, as Figures 1-7 As shown, the linkage mechanism 4 includes a second connecting plate 41 and a third connecting plate 43. Multiple first teeth 42 are provided on the upper part of the second connecting plate 41, and multiple second teeth 44 are provided on the lower part of the third connecting plate 43. A gear 45 is provided inside the connecting block 33. A fourth slider 46 is fixedly connected to the left side of the third connecting plate 43, a fifth slider 47 is fixedly connected to the rear side of the fourth slider 46, and a fourth connecting plate 48 is fixedly connected to the front side of the fourth slider 46. A second limiting post 49 is fixedly connected to the side of the fourth connecting plate 48 near the arc-shaped post 31. The multiple first teeth 42 and second teeth 44 mesh with the gear 45.

[0029] The effect achieved by the entire embodiment 2 is as follows: by setting the linkage mechanism 4, the second slider 36 drives the second connecting plate 41 to move, the first tooth 42 meshes with the gear 45, the second tooth 44 meshes with the gear 45, the third connecting plate 43 drives the fourth slider 46 and the fourth connecting plate 48 to move, and the second limiting post 49 disengages from the inside of the slot. The double locking mechanism plays a role in protecting the electronic display screen.

[0030] The working principle of the entire equipment is as follows: Installation and inspection phase: Before starting the test, ensure that all parts of the structure are in a stable state to prevent any part of the structure from malfunctioning after the work is completed.

[0031] Height adjustment stage: After the electronic display screen 12 is moved to a suitable position via the base plate 1, multiple electric telescopic rods 6 are activated simultaneously. The extended ends of the electric telescopic rods 6 drive the pad 7 to move towards the ground. At this time, the wheels 8 gradually move away from the ground. Then, the activation of the electric telescopic rods 6 is stopped, and the DC motor 5 is activated. The output shaft of the DC motor 5 drives the threaded rod 9 to rotate. The threaded rod 9 drives the sixth slider 10 to move up and down on the inner side of the support plate, thereby raising or lowering the electronic display screen 12.

[0032] Angle Adjustment Stage: During the angle adjustment stage of the electronic display screen 12, the limiting rod 35 is pulled outward. The limiting rod 35 causes the second slider 36 to slide inside the connecting block 33 away from the center of the connecting block 33, and the third slider 37 slides inside the connecting block 33. When the limiting rod 35 is pulled, the spring 38 deforms, and at the same time, the second slider 36 causes the first connecting plate 39 to move away from the center of the connecting block 33. The first limiting post 310 disengages from the inside of the slot 34. When the second slider 36 slides, it simultaneously causes the second connecting plate 41 to slide inside the connecting block 33, and the first tooth 42 engages with... Gear 45 meshes with the second tooth 44. The third connecting plate 43 drives the fourth slider 46 and the fifth slider 47 to slide inside the connecting block 33 away from the center of the connecting block 33. The fifth slider 47 simultaneously drives the fourth connecting plate 48 to slide in the same direction. The fourth connecting plate 48 drives the second limiting post 49 to disengage from the inside of the slot 34. The first slider 32 slides in an arc shape on the outside of the arc-shaped post 31, simultaneously driving the electronic display screen 12 to slide in an arc shape. After sliding to a suitable angle, the above operations are reversed, completing the engagement of the outer sides of the first limiting post 310 and the second limiting post 49 inside the slot 34.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
