[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown in the figure, a stable poster holder provided by this utility model embodiment includes a base plate 1 and a support rod 2. The support rod 2 is fixedly connected to the top of the base plate 1, and a mounting bracket 3 is fixedly connected to the top of the support rod 2. A sliding groove 4 is provided on the left side of the mounting bracket 3. A poster board 5 is placed inside the sliding groove 4. The poster board 5 is slidably connected to the inside of the sliding groove 4. A receiving groove 6 is provided inside the base plate 1.

[0023] refer to Figure 2 The bottom of the receiving groove 6 is rotatably connected to a turntable 7, which is cross-shaped. Each of the four corners of the bottom of the turntable 7 has a stroke groove 8. Each of the four corners of the bottom of the receiving groove 6 is fixedly connected to a limit frame 9. Each limit frame 9 has a support plate 10 inside it. Each support plate 10 is slidably connected to the inside of the limit frame 9. Each support plate 10 has a slider 11 fixedly connected to the top of it. Each slider 11 is slidably connected to the inside of the stroke groove 8.

[0024] By adopting the above solution, the smooth extension and retraction of the support plate 10 can be achieved by setting the turntable 7 and the limiting frame 9, which significantly increases the contact area between the bottom of the equipment and the ground, thereby greatly improving the overall stability.

[0025] refer to Figure 4 The top of the turntable 7 is fixedly connected to the limiting plate 12, the top of the base plate 1 is provided with a stabilizing groove 13, the bottom of the limiting plate 12 is slidably connected to the inside of the stabilizing groove 13, and the top of the limiting plate 12 is fixedly connected to the limiting component 14.

[0026] By adopting the above solution, the stability of the turntable 7 during rotation can be ensured by setting the stabilizing groove 13, and a precise locking mechanism is provided, thereby enhancing the overall structural stability of the equipment.

[0027] refer to Figure 3 The limiting component 14 includes a spring 1401, a connecting plate 1402, and a limiting rod 1403. A receiving block 15 is fixedly connected to the top of the limiting plate 12. A groove 16 is opened inside the receiving block 15. Two springs 1401 are fixedly connected to the top of the groove 16. The connecting plate 1402 is placed inside the groove 16. The bottom of each spring 1401 is fixedly connected to the top of the connecting plate 1402. The limiting rod 1403 is fixedly connected to the bottom of the connecting plate 1402. The bottom of the limiting rod 1403 passes through and extends out of the bottom of the limiting plate 12. A number of through holes 17 are equidistantly opened at the bottom of the stabilizing groove 13. The through holes 17 are used in conjunction with the limiting rod 1403.

[0028] By adopting the above solution, the automatic locking and unlocking function of the support plate 10 can be realized by setting the limiting component 14, thus ensuring the stability of the support plate 10 during the unfolding and retraction process.

[0029] refer to Figure 3Two stabilizing rods 18 are fixedly connected to the bottom of the groove 16. The top of each stabilizing rod 18 extends through and out of the top of the connecting plate 1402. The top of each stabilizing rod 18 is fixedly connected to the top of the groove 16. The connecting plate 1402 is slidably connected to the surface of the stabilizing rod 18.

[0030] By adopting the above solution, by setting the stabilizing rod 18, it can be ensured that the connecting plate 1402 slides smoothly along a straight line, and avoids it from shifting or rotating during the up and down movement.

[0031] refer to Figure 3 A pull handle 19 is placed on the top of the receiving block 15. The left and right sides of the bottom of the pull handle 19 penetrate the surface of the receiving block 15. The bottom of the pull handle 19 is fixedly connected to the top of the connecting plate 1402.

[0032] By adopting the above solution, the up and down movement of the connecting plate 1402 can be easily controlled manually by setting the pull handle 19, thereby realizing the cooperation action between the limit rod 1403 and the through hole 17, simplifying the unfolding and locking process of the support plate 10.

[0033] refer to Figure 1 Two locking blocks 20 are fixedly connected to the front side of the left surface of the mounting bracket 3, and a locking rod 21 is rotatably connected to the rear side of the left surface of the mounting bracket 3. The locking rod 21 cooperates with the locking blocks 20.

[0034] By adopting the above solution, by setting the locking block 20 and the locking rod 21, a safe fixing mechanism for the poster board 5 can be provided, ensuring that the poster board 5 can be firmly installed in the slide 4 and preventing it from accidentally falling off during the display process.

[0035] The working principle of this utility model:

[0036] In use, first, remove the locking rod 21 from the top of the locking block 20, then smoothly insert the poster board 5 along the slide groove 4. After installation, put the locking rod 21 back on top of the locking block 20 to ensure that the poster board 5 is stable and will not slip out accidentally. Then, move the entire device to the predetermined working position, and then use the pull handle 19 to pull the connecting plate 1402 upward. The connecting plate 1402 drives the limiting rod 1403 to move. After the limiting rod 1403 moves out of the through hole 17, the limiting plate can be rotated. 12. The rotation of the limiting plate 12 drives the turntable 7 to rotate, and the rotation of the turntable 7 drives the slider 11 to move. Then the slider 11 drives the support plate 10 to move along the limiting frame 9. When the support plate 10 extends out of the receiving groove 6, the pull handle 19 is released. At this time, the spring 1401 will reset the connecting plate 1402, thereby driving the limiting rod 1403 to insert into the through hole 17, thereby locking the support plate 10. This not only increases the contact area between the bottom of the equipment and the ground, but also significantly improves the overall stability.

[0037] In summary, this stable poster holder, through the coordinated use of a base plate 1, support rod 2, mounting bracket 3, sliding groove 4, poster board 5, receiving groove 6, turntable 7, travel groove 8, limiting bracket 9, support plate 10, slider 11, limiting plate 12, stabilizing groove 13, limiting component 14, receiving block 15, groove 16, through hole 17, stabilizing rod 18, pull handle 19, locking block 20, and locking rod 21, solves the problems of existing equipment often relying on relatively simple support structures, which may lead to insufficient stability on uneven ground. In addition, the operation of fixing or adjusting the poster board is not convenient and safe enough, increasing the complexity and difficulty of use.
