[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem that the display board is not easy to fix and fold when unfolded in the prior art, the following technical solution is disclosed. Figure 5-Figure 6As shown, a display board that is easy to fold includes a plate 3, which is located on the left and right sides of a transmission rod 6; and further includes: a folding mechanism includes a rotating shaft 13, which is rotatably connected to the left and right sides of the inside of the transmission rod 6, and the outer end of the rotating shaft 13 is connected to the plate 3 through the outer end of the rotating shaft 13, and the inner upper end of the transmission rod 6 is slidably connected to a limit rod 14; a folding mechanism is provided between the transmission rod 6 and the plate 3, which can fix the plate 3 and facilitate folding of the plate 3;

[0031] The upper end of the transmission rod 6 is rotatably connected to a screw rod 15, and the outer side of the screw rod 15 is threadedly connected to a limit rod 14, and the limit rod 14 is arranged in an inverted "U" shape;

[0032] A through hole 9 is formed at the inner upper end of the rotating shaft 13, and the inner part of the through hole 9 fits with the outer side of the limiting rod 14, and the limiting rod 14 can extend into the inner part of the through hole 9;

[0033] When it is necessary to open the sheet 3, move the required sheet 3 above the fixing rod 2, rotate the screw rod 15 by hand, the screw rod 15 rotates the limiting rod 14 to move up and down, and the limiting rod 14 moves upward. When the limiting rod 14 moves upward and separates from the through hole 9, the screw rod 15 is no longer rotated. At this time, the sheet 3 is pulled to both sides to unfold the sheet 3, and then the screw rod 15 is rotated in the opposite direction by hand. The screw rod 15 rotates to make the limiting rod 14 move downward, and the limiting rod 14 moves downward and engages in the inside of the through hole 9. Due to the structure of the through hole 9 and the limiting rod 14, the sheet 3 is limited. After the sheet 3 is fixed, the object to be displayed can be adhered to the sheet 3. When it is necessary to fold the sheet 3, repeat the above work, push the sheet 3 from the inside to realize the folding of the sheet 3, and the sheet 3 can be fixed after being folded to avoid the sheet 3 being loose after folding, so as to facilitate its folding.

[0034] Embodiment 2: A new technical solution is added on the basis of Embodiment 1. The number of plates 3 located in the fixed frame 1 can be changed according to the amount of objects to be displayed. Figure 1-Figure 2 As shown, the mounting plate 4 is welded to one end of the innermost plate 3, and the mounting plate 4 slides inside the fixing rod 2 at an equal angle; the fixing frame 1 is welded to the lower end of the fixing rod 2;

[0035] The interior of the fixing frame 1 is provided with placement grooves 5 at equal angles, and the placement grooves 5 correspond to the plate 3, and the radius of the fixing frame 1 is greater than the length of the plate 3 after folding;

[0036] Select a suitable number of plates 3 according to the number of objects to be displayed, pull the upper end of the plate 3 upward by hand, and the plate 3 moves upward to drive the mounting plate 4 to move upward synchronously during the upward movement. The mounting plate 4 slides upward inside the fixing rod 2, and the other plates 3 are located inside the fixing frame 1. When the display device needs to be moved, all the plates 3 are moved to the inside of the fixing frame 1, which is convenient for carrying the display device as a whole, and it can be adjusted according to the number of objects to be displayed on site;

[0037] Embodiment 3: A new technical solution is added on the basis of Embodiment 2 to fix the plate 3. The operation is simple. For details, see Figure 3-Figure 4 As shown, the upper end of the interior of the fixed frame 1 is rotatably connected with a threaded rod 8, and the outer side of the threaded rod 8 is threadedly connected with a push plate 7 at equal intervals, and the push plate 7 is arranged in a cylindrical structure, and the push plate 7 forms a sliding structure with the fixed frame 1 through the threaded rod 8, and the interior of the fixed frame 1 is slidably connected with a limit block 12 at equal angles, and the side of the limit block 12 close to the push plate 7 is arranged in an inclined structure, and a return spring 11 is arranged between the end of the limit block 12 close to the threaded rod 8 and the fixed frame 1, and the end of the mounting plate 4 close to the threaded rod 8 is provided with a card slot 10 at equal intervals, and the card slot 10 corresponds to the limit block 12 one by one;

[0038] When the plate 3 moves to the top, the threaded rod 8 is rotated forward by hand, and the threaded rod 8 rotates to make the push plate 7 move downward, and the push plate 7 moves downward to push the limit block 12, so that the limit block 12 moves into the mounting plate 4, so that the limit block 12 is located in the card slot 10 and fixed to the fixed frame 1, so as to fix the mounting plate 4. When the plate 3 needs to be placed in the fixed frame 1, the threaded rod 8 is rotated reversely by hand, and the threaded rod 8 rotates reversely to make the push plate 7 move upward, and the push plate 7 moves upward and separates from the limit block 12. At this time, the elastic force of the reset spring 11 makes the limit block 12 move into the fixed frame 1, and the limit block 12 separates from the plate 3, and then the plate 3 can be pushed.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
