Therefore, the role of the vision test chart adjustment bracket is very important. It can improve the reliability of vision testing and provide patients with better medical services.

[0003] However, in real life, the adjustment bracket of the traditional vision test chart used in physical examination centers is often fixed on the wall, with poor flexibility, and the adjustment bracket cannot be moved to different positions for vision testing, so the scope of use is limited. Secondly, the adjustment bracket of the traditional vision test chart used in physical examination centers has different adjustment directions and distances for vision testing, which is not only not conducive to the examinee observing the vision chart at different distances, making it impossible to compare and track changes in vision, and not conducive to a more comprehensive assessment of vision conditions, but also prone to reflections, resulting in an inaccurate vision detection structure.

On the one hand, it is beneficial for people of different heights to perform vision tests through the vision test chart on the adjustment bracket, ensuring that the adjustment bracket can be used for vision tests for different groups of people. On the other hand, by adjusting the height of the vision test chart through the adjustment bracket, it is beneficial for the examinee's eyes to be at the same horizontal position, so that the examinee's eyes can be kept in a comfortable state for vision testing, avoiding eye fatigue, which is beneficial to protect the eyes to a certain extent, and further ensuring the safety of the examinee when testing vision.

[0026] A counterweight plate 101 is provided on the top of the moving mechanism 1, and universal wheels 102 are provided at the four corners of the bottom of the counterweight plate 101. The vertical frame 2 is welded to the counterweight plate 101. By moving the universal wheels 102 at the bottom of the counterweight plate 101, it is convenient to move the adjustment bracket to different positions, which is not only convenient for preserving the vision test chart on the adjustment bracket, but also conducive to moving the adjustment bracket to different areas of the physical examination center to conduct physical examinations on the examinees.

[0027] Baffles 306 are welded at both ends of one side of the slide plate 304 away from the slider 307. The baffles 306 block the vision test chart on the plate 403. A screw hole compatible with the screw rod 303 is opened in the middle of the slider 307. Slide rails 305 are welded on both sides of the frame 301.

[0028] Both slide rails 305 are connected with slide grooves 308, and both slide grooves 308 are welded to the slide plate 304 to ensure that the height of the vision test chart on the up and down moving plate 403 is more stable, which is conducive to more stable testing of the eyes of examinees of different heights.

[0029] A push-pull unit 401 is provided on one side of the steering mechanism 4 close to the slide 304, and a side plate 4011 is provided at one end of the push-pull unit 401, and the side plate 4011 is connected to the slide 304 by bolts, and a hydraulic cylinder 4012 is bolted to the middle of one side of the side plate 4011, and a hydraulic rod 4013 is connected to one end of the hydraulic cylinder 4012, and a push plate 4014 is bolted to one end of the hydraulic rod 4013. The push plate 4014 at one end of the hydraulic rod 4013 is driven to move by the hydraulic cylinder 4012 on the push-pull unit 401, so as to facilitate the adjustment of the front and rear positions of the vision test chart on the bottom plate 403 of the rotating unit 402, which is beneficial for the examinee to observe the vision chart at different distances, to facilitate comparison and tracking of changes in vision, and to facilitate a more comprehensive assessment of the vision condition. The rotating unit 402 is provided in the middle of the bottom end of the push plate 4014, and the plate 403 is provided at the bottom of the rotating unit 402.

[0030] A second motor 4021 is installed on the top of the rotating unit 402, and a turntable 4022 is movably connected to the bottom of the second motor 4021 through a rotating shaft. The middle part of the top of the plate 403 is connected to the bottom of the turntable 4022 by bolts. When the second motor 4021 on the rotating unit 402 is turned on, the second motor 4021 drives the angle of the bottom plate 403 of the turntable 4022. Since different people have different light sensitivities, the angle of the vision test chart can be adjusted to avoid reflections and shadows, which is beneficial to reducing the impact of light on vision testing, thereby making it easier for the examinee to see the symbols on the vision test chart more quickly and clearly, avoiding extended testing time due to reflection problems, and further helping to improve testing efficiency.

[0031] By adjusting the position of the vision test chart on the plate 403 through the push-pull unit 401 and the rotation unit 402, on the one hand, it is convenient to hide the vision test chart to prevent unnecessary scratches on the vision test chart on the vision plate 403 by foreign objects, thereby playing a certain protective role on the vision test chart and further extending the service life of the vision test chart. On the other hand, by blocking the front of the vision test chart, it can effectively prevent the examinee from viewing the vision test chart in advance, ensuring that the vision test result is more accurate.

By turning on the first motor 302 on the lifting mechanism 3, it is convenient to adjust the height of the vision test chart, which is conducive to people of different heights to perform vision tests through the vision test chart on the adjustment bracket. It not only ensures that the adjustment bracket can be used for vision tests of different groups of people, but also helps the eyes of the examinee to be at the same horizontal position, so that the eyes of the examinee can be kept in a comfortable state for vision tests, avoiding eye fatigue, and playing a certain protective role for the eyes;

[0033] Then, the push plate 4014 at one end of the hydraulic rod 4013 is driven to move by the hydraulic cylinder 4012 on the push-pull unit 401, so as to adjust the front and rear positions of the vision test chart on the bottom plate 403 of the rotating unit 402, which is beneficial for the examinee to observe the vision chart at different distances, to compare and track the changes in vision, and to more comprehensively evaluate the vision status;

[0034] Finally, by turning on the second motor 4021 on the rotating unit 402 and adjusting the angle of the vision test chart, reflections and shadows can be avoided, which helps to reduce the impact of light on vision testing, thereby allowing the examinee to see the symbols on the vision test chart more quickly and clearly, avoiding extended testing time due to reflection problems, and further helping to improve testing efficiency.
