DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example 1: Please refer to Figure 1 - Figure 4 A movable smart classroom video display stand of the present embodiment includes a podium 1 and a video display stand body 2. A cover 3 is provided on the top of the podium 1. A plurality of rollers 4 are fixedly connected around the bottom of the podium 1. A groove 12 is processed on the bottom of the podium 1. A second motor 13 is provided at one end of the groove 12. A bidirectional threaded rod 14 is fixedly connected to one end of the second motor 13. A movable plate 16 is threadedly connected to both ends of the bidirectional threaded rod 14. A connecting rod 17 is fixedly connected to the bottom of the movable plate 16. Two vertical plates 18 are fixedly connected to both ends of the connecting rod 17. A plug block 19 is fixedly connected to one side of the vertical plate 18. One end of the plug block 19 is plug-connected to the inside of the roller 4.

[0023] When the podium 1 does not need to be moved, the insert block 19 will be inserted into the inside of the roller 4, thereby limiting the rotation of the wheels inside the roller 4. When the podium 1 needs to be moved, the second motor 13 is started, and the second motor 13 will drive the bidirectional threaded rod 14 to rotate. The rotation of the bidirectional threaded rod 14 will drive the two movable plates 16 to approach each other. The two movable plates 16 will respectively drive the two connecting rods 17 to approach each other. The connecting rods 17 will drive the two vertical plates 18 to move. The vertical plates 18 will drive the insert block 19 to move, so that the insert block 19 is separated from the inside of the roller 4, so that the wheels at the bottom of the roller 4 can rotate, and then the podium 1 can be moved;

[0024] Furthermore, two movable grooves 15 are processed at the bottom of the podium 1, and the top of the movable plate 16 is movably connected inside the movable groove 15. When the movable plate 16 moves, the movable plate 16 will move inside the movable groove 15. The movable groove 15 can keep the movable plate 16 in a stable state when moving;

[0025] Furthermore, the top of the vertical board 18 is fixedly connected with two limit blocks 20, and the bottom of the podium 1 is fixedly connected with a plurality of limit slots 21, and the two limit blocks 20 are movably connected inside the limit slots 21. When the insert block 19 moves, the insert block 19 will drive the vertical board 18 to move, and the vertical board 18 will drive the two limit blocks 20 to move, and the limit blocks 20 will move inside the limit slots 21. By setting the limit slots 21, the limit slots 21 will limit the movement of the vertical board 18, and at the same time keep the vertical board 18 in a stable state when moving;

[0026] Furthermore, the threads at both ends of the bidirectional threaded rod 14 are opposite to each other, so that when the bidirectional threaded rod 14 rotates, it will drive the two movable plates 16 to move closer to each other or away from each other.

[0027] Embodiment 2: The video display stand body 2 is located on the top surface of the podium 1, and a storage cavity 7 is provided inside the podium 1. A support block 5 is fixedly connected to the bottom of the video display stand body 2, and a movable block 6 is fixedly connected to one end of the support block 5, and a screw rod 9 is threadedly connected to one end of the movable block 6. The bottom of the screw rod 9 is fixedly connected to a first motor 8, and the top of the screw rod 9 is rotatably connected to the top inner wall of the storage cavity 7;

[0028] When the video display stand body 2 is not in use, the first motor 8 is started, the first motor 8 will drive the screw rod 9 to rotate, the screw rod 9 will drive the movable block 6 to move downward, the movable block 6 will drive the support block 5 to move downward, the support block 5 will drive the video display stand body 2 to move downward, so that the video display stand body 2 completely enters the storage cavity 7, and then the cover 3 is closed, so as to prevent the video display stand body 2 from being contaminated by dust;

[0029] Furthermore, a slide bar 10 is provided inside the storage cavity 7, and the two ends of the slide bar 10 are respectively fixedly connected to the top and bottom of the inner wall of the storage cavity 7, and the two ends of the support block 5 are movably connected to the outside of the slide bar 10. When the support block 5 moves downward, the two ends of the support block 5 will move downward along the outside of the slide bar 10, so that the support block 5 can be kept in a stable state when it moves downward through the slide bar 10, and then the video display stand body 2 can be kept in a stable state when it moves downward;

[0030] Furthermore, both ends of the support block 5 are movably connected to the outside of the slide rod 10, and the bottom of the slide rod 10 is fixedly connected to the limit ring 11. By setting the limit ring 11, the limit ring 11 will limit the movement of the support block 5. When the bottom of the support block 5 contacts the limit ring 11, the support block 5 will stop moving, and the video stand body 2 will be completely stored inside the podium 1.

[0031] Working principle: By starting the second motor 13, the second motor 13 will drive the bidirectional threaded rod 14 to rotate, and the rotation of the bidirectional threaded rod 14 will drive the two movable plates 16 and the two connecting rods 17 to approach each other, and the connecting rod 17 will drive the two vertical plates 18 to move, and the vertical plates 18 will drive the plug block 19 to move, so that the plug block 19 will be separated from the inside of the roller 4, so that the wheel at the bottom of the roller 4 can rotate, and then the podium 1 can be moved.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
