Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: an outdoor display screen that is convenient to carry and unfold, including a mounting bracket 1. A plurality of groups of screen assemblies 2 are threadedly installed inside the front side of the mounting bracket 1. Folding grooves 3 are opened on the upper and lower sides at the rear end of adjacent two mounting brackets 1. The rear side of the folding groove 3 is a communicating structure for not hindering the folding of the mounting bracket 1. A rotating shaft 4 is fixedly welded inside one folding groove 3. A connecting piece 5 is rotatably installed outside the rotating shaft 4. A moving groove 6 is opened inside the connecting piece 5. A rotating groove 7 communicating with the moving groove 6 is opened inside the connecting piece 5. A connecting block 8 is slidably installed inside the moving groove 6. The connecting block 8 is rotatably installed inside the rotating groove 7. The lower part of the connecting block 8 is fixedly welded to the other folding groove 3. By pulling one mounting bracket 1, the connecting block 8 moves along the moving groove 6 to the rotating groove 7, and the connecting block 8 can rotate around the rotating groove 7 to fold the mounting bracket 1;

[0022] Two groups of limit blocks 9 are fixedly welded to the outside of the connecting block 8 for restricting the height of the connecting piece 5. The limit blocks 9 are arranged on both sides of the connecting piece 5. A fixing groove 10 is formed in the upper part of one side mounting frame 1. A fixing piece 12 is slidably mounted inside the fixing groove 10. A limit rod 11 is fixedly welded to the lower part of the fixing piece 12. The lower part of the limit rod 11 penetrates into the folding groove 3 and abuts against one side of the limit block 9. By inserting the limit rod 11 into the folding groove 3, the limit rod 11 abuts against one side of the limit block 9 to prevent the connecting block 8 from moving along the moving groove 6 when the mounting frame 1 is laid flat; A first spring 13 is sleeved outside the limit rod 11. The upper and lower ends of the first spring 13 are fixedly welded to the fixing piece 12 and the fixing groove 10 respectively. The first spring 13 prevents the limit rod 11 from detaching from the folding groove 3 by pulling the fixing piece 12; A dismounting groove 17 is formed in the upper part of one side mounting frame 1. A connecting shaft 14 is slidably mounted inside the dismounting groove 17. A rotating piece 18 is fixedly connected to the upper part of the connecting shaft 14. The lower part of the connecting shaft 14 penetrates into the folding groove 3 and is fixedly welded with a threaded rod 15. The connecting shaft 14 is fixedly connected to the rotating shaft 4 through the threaded rod 15. By rotating the rotating piece 18 to rotate the connecting shaft 14, the threaded rod 15 disengages from the rotating shaft 4, so that the connecting shaft 14 disengages along the dismounting groove 17. By pushing down the mounting frame 1, the connecting piece 5 disengages from the upper part of the rotating shaft 4 to disconnect the connection between the two side mounting frames 1; A lower limit piece 19 is fixedly welded to the upper part of the rotating shaft 4. An upper limit piece 16 is fixedly welded to the lower part of the connecting shaft 14. The lower limit piece 19 and the upper limit piece 16 are opposite to the limit block 9 to support the other end of the connecting piece 5; Locking grooves 20 are formed on both sides of adjacent two side mounting frames 1. A fixing plate 22 is fixedly welded to the outside of one side locking groove 20. A connecting rod 26 is fixedly welded between the fixing plate 22 and the locking groove 20. A locking piece 23 is slidably mounted outside the connecting rod 26. A second spring 27 is fixedly welded between the locking piece 23 and the fixing plate 22. The second spring 27 is sleeved outside the connecting rod 26. A locking hole 24 is formed in the upper part of the locking piece 23. A positioning rod 25 for cooperating with the locking piece 23 is fixedly welded to the upper part of one side locking groove 20. A locking rod 21 for cooperating with the locking piece 23 is fixedly welded to the lower part of the other side locking groove 20. By pulling the locking piece 23, the locking piece 23 disengages from the positioning rod 25. When the two mounting frames 1 are folded, the locking piece 23 is rotated into the other side locking groove 20, the locking hole 24 is opposite to the locking rod 21, and the second spring 27 pushes the locking piece 23 to insert the locking rod 21 into the locking hole 24 to fix the folded mounting frame 1.

[0023] Working principle: When the utility model is in use, by pulling the mounting bracket 1 on one side, the connecting block 8 moves along the moving groove 6 to the rotating groove 7. The connecting block 8 can rotate around the rotating groove 7 to fold the mounting bracket 1. By pulling the locking piece 23, the locking piece 23 is disengaged from the positioning rod 25, and the locking piece 23 is rotated into the locking groove 20 on the other side. The locking hole 24 is aligned with the locking rod 21, and the second spring 27 pushes the locking piece 23 so that the locking rod 21 is inserted into the locking hole 24 to realize the fixation of the folded mounting bracket 1. When the mounting bracket 1 is unfolded, the first spring 13 pulls the fixing piece 12, and the limiting rod 11 is inserted into the folding groove 3. The limiting rod 11 abuts against one side of the limiting block 9 to prevent the connecting block 8 from moving along the moving groove 6 when the mounting bracket 1 is laid flat. By rotating the connecting shaft 14 through the rotating piece 18, the threaded rod 15 is disengaged from the rotating shaft 4, and the connecting shaft 14 is disengaged along the dismounting groove 17. By pushing the mounting bracket 1 downward, the connecting piece 5 is disengaged from the upper part of the rotating shaft 4 to disconnect the connection between the two side mounting brackets 1.
