[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A portable multimedia interactive display device includes a screen body 1, which is rectangular in shape. A slide rail 2 is fixed to the rear side wall of the screen body 1. The slide rail 2 is close to the upper end of the screen body 1 and parallel to the upper edge of the screen body 1. A slider 3 is slidably mounted inside the slide rail 2. A fastening screw is located at the left end of the slide rail 2. A support rod 4 is rotatably connected to the slider 3. The length of the support rod 4 is greater than the height of the screen body 1. A bushing 5 is fixed to the rear side wall of the screen body 1 near the lower left corner of the screen body 1. A rotating shaft is located inside the bushing 5. A support rod 6 is fixed to the outer end of the rotating shaft. A fastening bolt 7 is located on the bushing 5. The fastening bolt 7 fixes the rotating shaft relative to the bushing 5, thereby fixing the support rod 6. A limiting rod 8 is fixed to the left side wall of the screen body 1, located on one side of the bushing 5. The limiting rod 8 facilitates the rotation of the support rod 6. During the rapid positioning process, when the second support rod 6 is in contact with the first limit rod 8, the second support rod 6 is in a vertical state. A positioning plate 9 is fixedly installed in the middle of the first support rod 4. The positioning plate 9 has an opening, which is strip-shaped. A connecting plate 10 is fixedly installed on the rear side wall of the screen body 1. A positioning block 11 corresponding to the positioning plate 9 is fixedly installed on the connecting plate 10. When the slider 3 slides to the right end of the slide rail 2, the first support rod 4 is in a vertical state, and the positioning plate 9 is in contact with the positioning block 11. The positioning block 11 is provided with a second fastening bolt 12 and a nut 13 that is sleeved with the second fastening bolt 12. When fixing the first support rod 4, the nut 13 is placed in the opening. The nut 13 is in contact with the right wall of the positioning plate 9 and the front wall of the first support rod 4 respectively. Then, the second fastening bolt 12 is rotated to connect the nut 13, so that the positioning plate 9 and the positioning block 11 are fastened, thereby fixing the first support rod 4.

[0021] Supporting mechanisms are fixed on both support rod 4 and support rod 6, and a moving mechanism is provided on the lower side of the screen body 1.

[0022] The moving mechanism includes two sockets 14 symmetrically fixed to the lower wall of the screen body 1. A rod 15 is movably inserted into both sockets 14. Both ends of the rod 15 are fixed with bushings 16 located below the rod 15. A pivot is provided on each bushing 16. The pivot is perpendicular to the rod 15. Auxiliary wheels 17 are fixed at both ends of the pivot. A fastening screw is provided on the socket 14 near the left side of the screen body 1. The rod 15 is fixed relative to the socket 14 by the compression of the fastening screw.

[0023] The support mechanism includes a vertical support leg 1 20 and a support leg 21. The lower ends of both support legs 1 20 and support leg 21 are bent outwards and are symmetrically bent. A connecting rod 22 is fixed between support legs 1 20 and support leg 21. Support rod 1 4 and support rod 2 6 are fixedly connected to the corresponding support leg 1 20. When both support rod 1 4 and support rod 2 6 are vertical, the lower ends of the two support mechanisms are flush.

[0024] A handle 18 is fixed to the upper side of the screen body 1. A notch 19 corresponding to the handle 18 is opened on the upper wall of the screen body 1 to facilitate personnel to operate the handle 18. A limit rod 23 is fixed on the connecting plate 10. When it is necessary to move the screen body 1, the fastening bolt 22 and nut 13 are removed, the slider 3 is moved to the left end of the slide rail 2, and the slider 3 is fixed by the fastening screw 1. At this time, the support rod 4 and the support mechanism fixed thereto retract towards the screen body 1, and the support rod 4 rests on the limit rod 23. Then, the insertion rod 15 is taken out and the fastening bolt 7 is loosened. The support rod 26 is rotated so that the corresponding connecting rod 22 fits against the lower wall of the screen body 1. The insertion rod 15 is then inserted and the fastening screw 2 is tightened so that the insertion rod 15 limits the support rod 26 and its support mechanism. At this time, with the combined action of the handle 18 and the auxiliary wheel 17, the staff can move the screen body 1 and it is also easy to carry. Therefore, this device has high portability.
