A fixed shell 2 is fixed on the outside of the top of the main body 1. A first baffle 3 is slidably connected inside the fixed shell 2. A second baffle 4 is slidably connected inside the first baffle 3. The shapes of the fixed shell 2, the first baffle 3 and the second baffle 4 are all U-shaped, so that neither the first baffle 3 nor the second baffle 4 will脱离 the fixed shell 2 during sliding, and when the second baffle 4 extends outwards for a certain distance, it will drive the first baffle 3 to slide inside the fixed shell 2. A limiting plate 5 is fixed on one side of the first baffle 3 and inside the fixed shell 2, so that when the second baffle 4 moves back, it drives the first baffle 3 to move through the limiting plate 5;

[0034] The two ends of the fixed shell 2 are provided with moving blocks 6, one end of the moving block 6 is rotatably connected with a transmission rod 7, the center positions of the two transmission rods 7 are rotatably connected, and the end of the transmission rod 7 away from the moving block 6 is rotatably connected with an adjusting block 8, and the adjusting block 8 is slidably connected with the second baffle plate 4, so that the approaching movement of the two moving blocks 6 can drive the two adjusting blocks 8 to move through the transmission rod 7, so that the adjusting block 8 drives the second baffle plate 4 to extend to the outside of the fixed shell 2, and a telescopic driving motor 9 is fixed inside the fixed shell 2, and a telescopic worm 10 is connected to the output end of the telescopic driving motor 9, and a telescopic worm gear 11 is meshed and connected to one side of the telescopic worm 10, and a rotating shaft 12 is fixed inside the telescopic worm gear 11, and the rotating shaft 12 is rotatably connected with the fixed shell 2, so that the rotation of the rotating shaft 12 is more stable, and threaded sections 13 are provided at both ends of the outer side of the rotating shaft 12, and the thread rotation directions of the two threaded sections 13 are opposite, and the outer side of the threaded section 13 is threadedly connected with the moving block 6, so that the rotation of the threaded section 13 drives the moving block 6 to move.

[0035] In other embodiments, movable wheels may be provided at the bottom of the main body 1 so that the position of the main body 1 can be adjusted.

[0036] In this embodiment, a battery may be disposed inside the bottom of the main body 1 , and the battery provides power to the main body 1 and the telescopic drive motor 9 .

[0037] The use process of an anti-reflective outdoor screen provided by the utility model is as follows: when the main body 1 needs to be shielded when used outdoors, the telescopic drive motor 9 is powered on to drive the telescopic worm 10 to rotate, and the rotation of the telescopic worm 10 drives the meshing telescopic worm wheel 11 to rotate, and the rotation of the telescopic worm wheel 11 drives two thread segments 13 with opposite thread rotation directions to rotate through the rotating shaft 12, and the rotation of the thread segment 13 drives the moving block 6 connected with the external thread to move, so that the two moving blocks 6 move closer, and the movement of the moving block 6 drives the adjustment block 8 to move through the rotationally connected transmission rod 7, and according to the extension of the transmission rod 7 when rotating and the sliding of the adjustment block 8 inside the second shielding plate 4, the second shielding plate 4 is driven to extend out of the fixed shell 2, and when the second shielding plate 4 extends the moving distance, it drives the first shielding plate 3 to extend out of the fixed shell 2, thereby preventing the screen of the main body 1 from reflecting;

[0038] When the second baffle plate 4 is retracted, the telescopic drive motor 9 controls the reversal of the telescopic worm 10, and the telescopic worm 10 drives the rotating shaft 12 through the telescopic worm gear 11 to drive the threaded segment 13 to rotate. The rotation of the two threaded segments 13 controls the two moving blocks 6 to move away from each other, and the moving block 6 drives the second baffle plate 4 to move toward the inside of the fixed shell 2 through the transmission rod 7 and the adjustment block 8. After the second baffle plate 4 moves a certain distance, it drives the first baffle plate 3 to continue to retract and move through the limit plate 5.

The first positioning plate 15 is fixed to the top of the extension plate 14 near the second shielding plate 4. The first positioning plate 15 is slidably connected to the second shielding plate 4, so that the first positioning plate 15 can slide on the top of the second shielding plate 4 by descending. The second positioning bolts 17 are fixed to both ends of the bottom of one side of the extension plate 14. The second positioning plate 16 is in an L-shape, and is slidably connected to the second baffle plate 4, so that the second positioning plate 16 enters the interior of the second baffle plate 4 by translation and then is positioned by descending.

The internal thread on the top of the extension plate 14 is connected with a positioning bolt 17, and the positioning bolt 17 is slidably connected to the second baffle plate 4, so that when the positioning bolt 17 is inside the second baffle plate 4, the first positioning plate 15 and the second positioning plate 16 cannot rise.

[0041] In this embodiment, a side of the extension plate 14 away from the second shielding plate 4 is provided with an assembly groove for mounting the first positioning plate 15 and the second positioning plate 16 , thereby facilitating the assembly of multiple extension plates 14 .

[0042] The use process of an anti-reflective outdoor screen provided by the utility model is as follows: when it is necessary to lengthen one side of the second baffle plate 4 to ensure a better shading effect, firstly, the second positioning plate 16 is translated into the interior of the second baffle plate 4, at which time the extension plate 14 contacts the second baffle plate 4, and then the extension plate 14 is lowered, so that the extension plate 14 drives the first positioning plate 15 and the second positioning plate 16 to descend, so that the first positioning plate 15 and the second positioning plate 16 move inside the second baffle plate 4 by descending, and at this time the extension plate 14 cannot be separated from the second baffle plate 4 by translation, and then the positioning bolt 17 is rotated, so that the positioning bolt 17 extends out from the inside of the second baffle plate 4 and enters the inside of the slidingly connected second baffle plate 4, thereby positioning the extension plate 14 on the lifting and lowering of one side of the second baffle plate 4, and then providing the main body 1 with a better shading effect through the added extension plate 14, thereby facilitating the viewing clarity of bystanders.
