"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] As described in the background art, in the current related technologies, due to the limitation of exhibition space, many exhibition screens can only be fixed on the walls of the exhibition, making it difficult for users to find the video content on the exhibition screens immediately after entering the exhibition. In other related technologies, in order to make the exhibition screens easier to view, some exhibition screens are set in the center of the exhibition. However, this design will not only block the transportation of other objects in the exhibition when the exhibition is not open, but also increase the difficulty of cleaning the exhibition site.

[0037] In order to solve the above problems, the present invention provides a mobile device for exhibition screens. Figure 1 and Figure 2 , the exhibition screen moving device comprises: a first screen body 1 and a first sliding track group 6;

[0038] The first sliding track group 6 includes a first sub-track 61 and a second sub-track 62; the first sub-track 61 and the second sub-track 62 are both U-shaped tracks, and the first sub-track 61 is nested in the second sub-track 62, the first part of the first sub-track 61 is parallel to the second sub-track 62 and separated by a preset distance, and the second part of the first sub-track 61 is aligned with the second sub-track 62;

[0040] In this embodiment, reference Figure 1, both ends of the first sliding track group can be set at a position close to the wall 13, so that the first screen body 1 can be moved to a position close to the wall by the first sliding track group 6 ( Figure 1 In some embodiments, the first screen body can be moved from Figure 1 Starting from the position close to the wall 13, the first screen body moves horizontally along the first sub-track 61 and the second sub-track 62 (i.e., along the first part of the first sub-track), and then moves to the first turn of the U-shaped track, and then the first screen body moves sideways, that is, begins to enter the second part of the first sub-track, and then moves to the second turn of the U-shaped track, and then the first screen body starts to turn and move, and finally moves to the position shown in FIG. Fig. 9 Optionally, the first screen body can also be located at Fig. 9 Move to the position in Figure 1 The position in is not limited.

[0041] It should be noted that the first sliding track group can be set on the top or the ground of the exhibition site, and there is no limitation on this. The first screen body and the first connecting component can rotate along a plane perpendicular to the first connecting component, thereby ensuring that the first screen body and the sliding track can rotate relative to each other, so that the first screen body can complete the turning movement in the first sliding track group.

[0051] In this embodiment, the specific number of the first pulley and the second pulley can be set as needed. Generally, in order to maintain balance, the number of the first pulley and the second pulley is an even number.
