[0031] like Figure 1 and Figure 3 As shown, the bottom of the storage tube 6 is provided with an auxiliary component 13 for installation in different environments, and the auxiliary component 13 is provided with four groups, the auxiliary component 13 includes a connecting plate 1301 and a top plate 1302, and the top plate 1302 is provided on the top of the connecting plate 1301, and the connecting plate 1301 and the top plate 1302 form an "L"-shaped structure, the auxiliary component 13 also includes a threaded rod 1303 and a positioning plate 1304, and the threaded rod 1303 is installed on the internal thread of the connecting plate 1301, and the positioning plate 1304 is rotatably installed on the end of the threaded rod 1303, and the positioning plate 1304 is slidably arranged on the bottom outer surface of the top plate 1302. On the surface, when there is no need to use the bottom frame 1, the connecting frame 2, the connecting frame 3 and the supporting plate 4 of the multimedia display support structure, the user can pull the storage tube 6 upwards to separate the card plate 2104 on one side of the storage tube 6 from the installation frame 2103, so that the entire projection structure is separated from the support structure, and the user can rotate the threaded rod 1303 clockwise or counterclockwise to control the distance of the positioning plate 1304 relative to the connecting plate 1301 through the rotation of the threaded rod 1303, so as to facilitate the clamping and fixing of the installation surface required for hanging or fixing, and is conducive to directly using the auxiliary component 13 to directly fix and display the multimedia display device.

[0032] In summary, if Figure 1-Figure 7As shown, the multimedia display device with fast assembly, when used, when carried to the required position for assembly, the connection frame 3 can be rotated through the design of the rotation connection between the built-in connecting rod 20 and the turntable 19, and there is a damping effect between the built-in connecting rod 20 and the turntable 19, and the rotation range is 0-90°, so that the connection frame 3 and the support plate 4 are in a vertical state with respect to the bottom frame 1, which is convenient for longitudinal support of the display device, and then the design of the servo motor 12 can drive the reel 11 to rotate, so that the projection screen 7 rolled up outside it can be unfolded downward by the rotation of the reel 11. When the projection screen 7 is rolled up, the bottom groove design of the storage tube 6 can be used to properly clean the projection screen 7 to prevent insects or other foreign objects from being attached to the projection screen 7. The storage tube 6 has a certain cleaning effect, and the counterweight plate 8 can be used to close and block the groove from the bottom of the storage tube 6 to prevent foreign matter from entering the storage tube 6 and causing damage to the projection screen 7. Then the projector 17 can slide along the built-in rod 1504 in a horizontal position by utilizing the design of the connecting sleeve 16, and the number of projectors 17 and projectors 17 is not limited, which is convenient for displaying multiple information on the projection screen 7, and is conducive to viewing multiple multimedia information at the same time, without the need to assemble another set of multimedia display devices. The design of the hydraulic rod 1501 and the end plate 1502 can drive the entire auxiliary frame 1503 to move closer to and away from the projection screen 7, which is convenient for flexible adjustment according to the projection display distance. The entire mounting plate 14 is threadedly connected to the auxiliary cover 5 , which is convenient for users to disassemble the entire multimedia display device and to carry out targeted maintenance and replacement when a fault occurs. Secondly, the rotating connection design of the rotating shaft 2101 and the sleeve 2102 facilitates the synchronous rotation of the installation frame 2103 connected to the sleeve 2102. After the rotation is completed, the screw design can be used to penetrate the inside of the collection plate 10 and limit and fix it with the sleeve 2102 to ensure stability after the angle is adjusted, so as to facilitate the card plate 2104 connected to the storage tube 6 to be inserted into the installation frame 2103 for assembly. The design of the servo motor 12 can drive the reel 11 to rotate, so that the projection screen 7 rolled up outside it can be unfolded downward by the rotation of the reel 11, which is convenient for projecting multimedia display on the projection screen 7. The storage device can be self-protected and easy to carry at the same time. The display and support structures are designed independently. In addition, when the bottom frame 1, the connecting frame 2, the connecting frame 3 and the supporting plate 4 of the multimedia display support structure are not needed, the user can pull the storage tube 6 upward to separate the card plate 2104 on one side of the storage tube 6 from the installation frame 2103, so that the entire projection structure is separated from the support structure. The user can rotate the threaded rod 1303 clockwise or counterclockwise to control the distance of the positioning plate 1304 with respect to the connecting plate 1301, so as to facilitate the clamping and fixing of the installation surface required for hanging or fixing, which is conducive to directly using the auxiliary component 13 to directly fix and display the multimedia display device.Finally, after use, the connection frame 3 can be rotated through the design of the built-in connecting rod 20 and the rotating disk 19, so that the connection frame 3 and the support plate 4 can be rotated to the bottom frame 1 area, and the storage tube 6 can be protected by the shape and structure design of the bottom frame 1. The bottom frame 1 has storage protection and can also be filled with stones or other heavy objects according to the required moving position, ensuring that the bottom frame 1 is stable in support and use while being easy to carry.
