Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-5, the utility model provides a technical solution: a movable LED screen during performances, including: the first LED screen 2 is installed on the front side of the upper end of the mounting frame 1, and the lower side of the mounting frame 1 A support frame 3 is provided, the inner end of the support frame 3 is equipped with a limiting plate 4, and the inner side of the limiting plate 4 is provided with a mounting plate 5, and a fixing block 6 is installed at the connection between the mounting plate 5 and the limiting plate 4 ;

Adjusting rod 7, it is arranged on the lower side of mounting plate 5 and is connected with support frame 3, the pulley 8 that is connected with mounting plate 5 is installed on the outside of described adjusting rod 7, and the front side of mounting plate 5 is provided with protective Frame 9, a turning handle 10 is installed at the connection between the mounting plate 5 and the protective frame 9, and a positioning component 11 is arranged at the connection between the turning handle 10 and the protective frame 9;

The second LED screen 15 is installed on the inner side of the protective frame 9, the connection between the second LED screen 15 and the protective frame 9 is provided with a protective plate 12, and the connection between the protective frame 9 and the protective plate 12 is provided with a positioning ball 13, and a first spring 14 is installed at the joint between the positioning ball 13 and the protective frame 9 .

When using the movable LED screen in this performance, first, as shown in Figure 1, Figure 2 and Figure 3, the installation frame 1 and the support frame 3 are installed on the required performance site, and the protective frame 9 is located on the first LED screen 2 When the performance is performed, since the installation plate 5 forms a translation structure on the inner side of the limit plate 4 through the fixed block 6, and the installation plate 5 and the adjustment rod 7 are connected in a threaded manner, so that the adjustment rod 7 moves when the motor is started. Rotate, and then the mounting plate 5 is displaced by the pulley 8. At this time, the position of the second LED screen 15 changes. Since the protective plate 12 and the protective frame 9 are respectively wrapped with the second LED screen 15, the second LED screen 15 The periphery and corners of the screen 15 will not directly contact with foreign objects, so the second LED screen 15 is protected.

Finally, as shown in Fig. 3, Fig. 4 and Fig. 5, when the second LED screen 15 needs to be overhauled, first pull the connecting plate 1102 to the front side, because the positioning block 1101 forms a slide on the inner side of the handle 10 through the connecting plate 1102 structure, and the positioning block 1101 is connected to the protective frame 9 in a snap-fitting manner. At this time, the second spring 1103 shrinks, and then the positioning block 1101 shrinks, so that the positioning assembly 11 no longer positions the protective frame 9, and then the rotating Rotate 10 to the outside, and at the same time, because the positioning ball 13 forms elastic expansion and contraction inside the protective frame 9 through the first spring 14, and the positioning ball 13 is connected with the protective plate 12 in an engaging manner, and the protective plate 12 is on the protective frame 9. The outer side constitutes a rotating structure, so that when the protective plate 12 rotates outward, the positioning ball 13 shrinks, and then the protective plate 12 is no longer fixed to the protective frame 9. At this time, after the protective plate 12 is rotated and opened, the second LED screen 15 Take out from protective frame 9 and carry out overhaul, Here it is the whole process that the movable LED screen in the performance uses.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacements and modifications, the scope of the present utility model is defined by the appended claims and their equivalents.
