The take-up roller 7 is movably installed in the middle of the interior of the screen box 1. Shafts 8 are fixedly installed on both sides of the take-up roller 7. The left shaft 8 is rotatably connected to the left inner wall of the screen box 1, and the right shaft 8... 8 is rotatably connected to the shaft hole 5 and extends to the outside of the curtain box 1. A knob seat 9 is fixedly installed at the tail end of the right shaft 8. Multiple turns of curtain 10 are wound on the take-up roller 7. The top of the curtain 10 extends through the fabric outlet groove 6 to the outside of the curtain box 1. A curtain rod 11 is fixedly installed on the top of the curtain 10. Positioning holes 12 are fixedly installed on both sides of the bottom of the curtain rod 11. Bases 13 are fixedly installed on both sides of the upper surface of the curtain box 1. A first support rod 14 is rotatably connected inside the two bases 13. A first threaded hole 15 is fixedly installed on the top surface of the first support rod 14. A second support rod 16 is movably installed inside the two first support rods 14. Multiple second threaded holes 17 are fixedly installed on the surface of the second support rod 16. Bolts 18 are threaded into the first threaded hole 15 and the second threaded hole 17.

[0028] In this embodiment, the take-up roller 7 and the fabric outlet trough 6 are vertically aligned.

[0029] In practical use, by pulling the curtain rod 11 upward, the winding roller 7 can rotate and move, allowing the curtain 10 wound on the winding roller 7 to move out to the fabric outlet 6 and slowly unfold upward, so that the curtain 10 inside the curtain box 1 can be fully unfolded; and when it is necessary to store the curtain 10, rotating the knob seat 9 can drive the winding roller 7 to rotate and move, so that the curtain 10 can be moved into the curtain box 1 through the fabric outlet 6 and wound onto the winding roller 7, so that the curtain 10 can be completely stored inside the curtain box 1, thus making the curtain 10 easy to store and carry.

[0030] In this embodiment, the two first support rods 14 and the two second support rods 16 are arranged in a symmetrical structure, and the top of the second support rod 16 and the inside of the positioning hole 12 are inlaid.

[0031] In practical use, the first support rods 14 on both sides of the screen box 1 are rotated outwards to open and stand upright, and the second support rod 16 can be simultaneously placed upright. Then, by embedding the top of the second support rod 16 into the positioning hole 12, the screen 10 can be supported on both sides, allowing the screen 10 to be vertically unfolded on the ground. When the screen 10 is not in use, it can be stored inside the screen box 1, and the second support rod 16 can be retracted into the first support rod 14. Then, rotating the first support rod 14 inwards will allow it to be placed horizontally on the screen box 1, so that the first support rod 14 can be stored together with the screen 10, saving space and making it easy to carry.

[0032] In this embodiment, the second support rod 16 is internally adapted to the first support rod 14.

[0033] In practical use, the support height of the second support rod 16 can be adjusted by extending and retracting inside the first support rod 14.

[0034] In this embodiment, four support rods 4 are provided, and the four support rods 4 are arranged in a symmetrical structure in pairs.

[0035] In practical use, by rotating the support rod 4 outward from inside the bottom groove 2, the support area of ​​the screen box 1 can be increased, thereby improving the support stability of the screen 10; and when the support rod 4 is not needed, it can be rotated back into the bottom groove 2, which does not take up space and is convenient to use.

[0036] The working principle of the digital media display device mentioned in this utility model:

[0037] In use, by pulling the curtain rod 11 upward, the winding roller 7 can rotate and move, allowing the curtain 10 wound on the winding roller 7 to move out to the fabric outlet 6 and slowly unfold upward, so that the curtain 10 inside the curtain box 1 can be fully unfolded; and when it is necessary to store the curtain 10, rotating the knob seat 9 can drive the winding roller 7 to rotate and move, so that the curtain 10 can be moved into the curtain box 1 through the fabric outlet 6 and wound onto the winding roller 7, so that the curtain 10 can be completely stored inside the curtain box 1, thus making the curtain 10 easy to store and carry.

[0038] Then, by rotating the first support rods 14 on both sides of the screen box 1 outwards to open them for vertical placement, and simultaneously, the second support rod 16 can be placed vertically at the same time as the first support rod 14. Then, by embedding the top of the second support rod 16 into the positioning hole 12, it can support both sides of the screen 10, allowing the screen 10 to be vertically unfolded on the ground, thus supporting the screen. When the screen 10 is not in use, the screen 10 can be stored inside the screen box 1, and the second support rod 16 can be retracted into the first support rod 14. Then, by rotating the first support rod 14 inwards, the first support rod 14 can be placed horizontally on the screen box 1, so that the first support rod 14 can be stored together with the screen 10, saving space and making it easy to carry.

[0039] Meanwhile, by extending and retracting the second support rod 16 inside the first support rod 14, the support height of the second support rod 16 can be adjusted. Thus, the support height of the second support rod 16 can be adjusted to a suitable position according to the unfolding height of the curtain 10, thereby supporting and placing the curtain 10 at different unfolding heights and improving practicality.

[0040] Meanwhile, by rotating the support rod 4 outward from inside the bottom groove 2, the support area of ​​the screen box 1 can be increased, thereby improving the support stability of the screen 10; and when the support rod 4 is not needed, it can be rotated back into the bottom groove 2, which does not take up space and is convenient to use.
