The extension display board is installed in the grooves, and a limiting block is set at the bottom of the extension display board near the innermost end of the groove. By setting up the extension display board to expand the display range, the display needs can be met. However, the above method has the following defects in actual use: Although the display range can be expanded by pulling the display board, after expansion, there is a thickness difference between the display position of the extension display board and the board body, resulting in an uneven display area, which affects the laying of popular science content. Moreover, after expanding the display range, the entire display area is presented as a flat plane, providing users with a single perspective and requiring them to walk around to view, resulting in a mediocre popular science effect.

[0004] Therefore, a portable public health science popularization display board is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-6 As shown, a portable public health science popularization display board includes a support 100 and a display board body 200 installed on top of it; it also includes an expansion mechanism 300, of which there are two. The expansion mechanism 300 is disposed on the outside of the display board body 200 and is used to expand the usable area of ​​the display board body 200; wherein, the expansion mechanism 300 includes a placement box 310 and a set of movable expansion plates 320, the expansion plates 320 are disposed inside the placement box 310 and arranged in sequence.

[0025] like Figure 3 and Figure 4 As shown, the expansion mechanism 300 also includes a set of springs 330 and a set of T-shaped rods 340. The springs 330 are in a compressed state, and the T-shaped rods 340 extend and are hinged to the interior of the expansion plate 320. One end of the T-shaped rods 340 passes through and slides to the outside of the placement box 310. One end of the springs 330 is installed inside the expansion plate 320, and the other end of the springs 330 is installed to the inner wall of the placement box 310.

[0026] The support bracket 100 supports the main body 200 of the display board. When expanding the display area, the user can move the placement box 310. When the corresponding extension plate 320 is fully exposed and not blocked by the main body 200 of the display board, the spring 330 will push the extension plate 320 to move, so that the extension plate 320 is aligned with the main body 200 of the display board, thus expanding the display area. At this time, the T-shaped rod 340 will follow the movement. When it is necessary to adjust the extension plate 320 to a curved display later, the corresponding extension plate 320 can be pushed outward again, and then rotated at the corresponding angle along the hinge point between the T-shaped rod 340 and the extension plate 320.

[0027] like Figure 3 and Figure 4 As shown, the placement box 310 is provided with a support rod 311 that passes through its interior. The outer side of one end of the support rod 311 is smooth, and the outer side of the other end of the support rod 311 is provided with a threaded groove that can be threadedly connected to the placement box 310.

[0028] When the expansion plate 320 is used for external expansion, the smooth end on the support rod 311 will move into the interior of the placement box 310. Then, when it is necessary to adjust the expansion plate 320, the user can connect the threaded end on the support rod 311 to the threaded interior of the placement box 310, and then rotate the support rod 311 to make it move against the expansion plate 320 to complete the adjustment.

[0029] like Figure 2 As shown, a slider 312 is installed on one side of the placement box 310 and is slidably connected to the outside of the display board body 200. The slider 312 and the display board body 200 slide against each other.

[0030] When using the expansion board 320, the user can push the slider 312 to move the placement box 310. Since the slider 312 and the display board body 200 slide against each other, the frictional resistance between them can achieve a stable effect after the slide is in place, reducing the occurrence of accidental movement during use.

[0031] like Figure 3 and Figure 4 As shown, a set of insertion holes are provided on the T-shaped rod 340, and an insertion rod 341 is provided on the outside of the T-shaped rod 340 and is slidably connected to the outside of the placement box 310. The insertion rod 341 is adapted to the insertion holes.

[0032] When the extension plate 320 needs to be curved, the user needs to push the T-shaped rod 340 to make the extension plate 320 move again. After the movement is in place, the user can insert the plug rod 341 into the corresponding plug hole to complete the fixing of the T-shaped rod 340 and the extension plate 320.

[0033] like Figure 1 As shown, a set of casters is installed at the bottom of bracket 100.

[0034] The use of casters makes it easy to move the entire device flexibly and set it in the corresponding position according to the user's needs.

[0035] like Figure 4 As shown, a ball bearing is provided at one end of the support rod 311, and the outer side of the ball bearing contacts the outer side of the extension plate 320.

[0036] The use of ball bearings reduces wear between the support rod 311 and the extension plate 320 during adjustment, thus extending the service life of the equipment.

[0037] Working Principle: The support bracket 100 supports the main body 200 of the display panel. The use of casters allows for flexible movement of the entire device. It can be positioned according to user needs. To expand the display area, the user can move the placement box 310. When the corresponding extension plate 320 is fully exposed and not obstructed by the main body 200, the spring 330 will push the extension plate 320 to align with the main body 200, thus expanding the display area. The T-shaped rod 340 will then move accordingly. The user can then insert the insertion rod 341 into the corresponding hole to secure it. To adjust the extension plate 320 to a curved display position, the user can detach the insertion rod 341 from the hole and then push the T-shaped rod 340 to move it. The extension plate 320 moves again. After it reaches its position, the user can insert the rod 341 into the corresponding hole to fix the T-shaped rod 340 and the extension plate 320. Then, the user can connect the threaded end of the support rod 311 to the internal thread of the placement box 310, and then rotate the support rod 311 to make it move against the extension plate 320, so that the corresponding extension plate 320 rotates to the corresponding angle, completing the curved display setting. The entire device can expand the display range while keeping the entire device area flat, which is convenient for laying out public health science popularization content. At the same time, after the display range is expanded, the angles of its two sides can be adjusted to present a curved display state, providing users with a wider viewing angle, reducing the phenomenon of walking around to view, enhancing the immersive experience, and thus improving the effect of science popularization.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
