Detailed Implementation

[0024] 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.

[0025] Referring to Figures 1-3, one embodiment of this utility model provides: a foldable support billboard display stand, including an outer support rod 1, an inner support rod 2 rotatably connected to the inner wall of the outer support rod 1, support feet 5 rotatably connected to the bottom ends of the outer support rod 1 and the inner support rod 2, a round rod 3 rotatably connected to the inner wall of the inner support rod 2, the outer edge of the round rod 3 rotatably connected to the inner wall of the outer support rod 1, a rotating ring 11 rotatably connected to the middle of the outer wall of the round rod 3, and a first connecting rod 6 rotatably connected to the inner wall of the inner support rod 2. The other end of the rod 6 is rotatably connected to the second connecting rod 7. The other end of the second connecting rod 7 is rotatably connected to the inner wall of the outer supporting rod 1. The inner wall of the second connecting rod 7 is slidably connected to the limiting plate 8. One end of the limiting plate 8 is fixedly connected to the stop block 10. The other end of the limiting plate 8 is fixedly connected to the limiting rod 9. The outer wall of the limiting rod 9 is slidably connected to the inner wall of the first connecting rod 6. The supporting feet 5 at the bottom of the outer supporting rod 1 are rotatably connected to both sides of the outer wall of the outer supporting rod 1. The supporting feet 5 at the bottom of the inner supporting rod 2 are rotatably connected to the middle of the bottom of the inner supporting rod 2.

[0026] Specifically, both the outer support rod 1 and the inner support rod 2 have inner grooves, allowing them to fold together. The width of the support foot 5 at the bottom of the inner support rod 2 is smaller than the width of the inner groove of the outer support rod 1, so that it does not hinder the folding of the inner support rod 2 into the outer support rod 1. The two ends of the limiting plate 8 are slidably connected to the first connecting rod 6 and the second connecting rod 7 through limiting rods 9. The other end of the limiting rod 9, which is slidably connected to the inner wall of the second connecting rod 7, is provided with a stop block 10. The stop block 10 is larger than the width of the sliding groove of the limiting rod 9, so that the limiting plate 8 will not fall off the inner wall of the second connecting rod 7, and the limiting rod 9 is allowed to slide out from the inner wall of the first connecting rod 6.

[0027] Referring to Figures 2, 4, and 5, a connecting rod 15 is fixedly connected to the outer wall of the rotating ring 11, and two sets of round wheels 16 are fixedly connected to the other end of the connecting rod 15. Several positioning holes are opened around the rotating surface of the rotating ring 11. A fixing plate 12 is fixedly connected to the outer wall of the round rod 3, and a positioning rod 13 is slidably connected to the inner wall of the fixing plate 12. One end of the positioning rod 13 is rotatably connected to a limit pin 14 so that the positioning rod 13 will not fall out of the positioning hole. A rotating wheel 17 is rotatably connected between the two round wheels 16. A display plate 4 is fixedly connected to the outer wall of the rotating wheel 17, and several limit grooves are opened around the outer wall of the rotating wheel 17. A clamping plate 18 is slidably connected to the inner wall of the connecting rod 15. Pull rods 19 are fixedly connected to both sides of the clamping plate 18. A spring 20 is fixedly connected to the inner wall of the connecting rod 15, and the other end of the spring 20 is fixedly connected to the outer wall of the clamping plate 18.

[0028] Specifically, rotate the limiting pin 14 so that it can pass through the positioning hole and unlock the positioning rod 13. Then pull the positioning rod 13 out of the positioning hole of the rotating ring 11. At this time, the rotating ring 11 can rotate freely around the round rod 3. The limiting pin 14 fixes the positioning rod 13 to prevent it from falling out of the positioning hole. The rotating wheel 17 rotates between the two sets of round wheels 16. The display plate 4 can freely adjust its height and tilt angle within a certain range as the rotating wheel 17 rotates. When it is adjusted to a suitable position, the operator releases the pull rod 19, the spring 20 returns to its deformation, and pushes the locking plate 18 to re-lock into the limiting groove of the rotating wheel 17, fixing the display plate 4 in that position.

[0029] Working principle: When the exhibition frame needs to be deployed, the operator holds the outer support rod 1 and the inner support rod 2 with both hands and applies force outward to rotate them. During rotation, the support feet 5, which are rotatably connected to the bottom ends of the outer support rod 1 and the inner support rod 2, unfold synchronously, rotating from a retracted state close to the rod body to a horizontal state, contacting the ground. At the same time, the limiting component between the outer support rod 1 and the inner support rod 2 comes into play. One end of the first connecting rod 6 in the limiting component is rotatably connected to the inner wall of the inner support rod 2, and the other end is rotatably connected to the second connecting rod 7. The other end of the second connecting rod 7 is rotatably connected to the inner wall of the outer support rod 1. As the outer support rod 1 and the inner support rod 2 rotate, the first connecting rod 6 and the second connecting rod 7 rotate relative to each other. When the first connecting rod 6 and the second connecting rod 7 rotate to a horizontal state, the limiting plate 8 is pushed toward the first connecting rod 6, so that the limiting rod 9 is inserted into the first connecting rod 6. Thus, under the limiting of the first connecting rod 6 and the second connecting rod 7 by the limiting plate 8, the rotation angle of the outer support rod 1 and the inner support rod 2 is limited, so that the display stand unfolds stably and remains at that angle, forming a stable support structure.

[0030] To adjust the rotation angle of display panel 4, the operator first rotates the limiting pin 14 to allow it to pass through the positioning hole and unlock the positioning rod 13. Then, the positioning rod 13 is pulled out of the positioning hole of the rotating ring 11, allowing the rotating ring 11 to rotate freely around the circular rod 3. The operator rotates display panel 4, which drives the rotating ring 11 to rotate via the connecting rod 15. Once the desired angle is reached, the positioning rod 13 is inserted into the corresponding positioning hole of the rotating ring 11. The limiting pin 14 is then rotated to fix the positioning rod 13, preventing it from falling out of the positioning hole. The pull rod 19 is then pulled, causing the locking plate 18 to slide against the inner wall of the connecting rod 15, overcoming the spring force of the spring 20 and separating the locking plate 18 from the limiting groove on the outer wall of the rotating wheel 17. At this point, display panel 4 can freely adjust its height and tilt angle within a certain range as the rotating wheel 17 rotates. Once the position is adjusted, the operator releases the lever 19, the spring 20 returns to its original shape, and pushes the locking plate 18 back into the limiting groove of the rotating wheel 17, fixing the display plate 4 in that position and completing the adjustment of the height and tilt angle.

[0031] After use, first, adjust the display panel 4 to a suitable position, pull the lever 19 of the adjustment component to separate the locking plate 18 from the limiting groove of the rotating wheel 17, and fold the display panel 4 to a state that is easy to store. Next, pull the limiting plate 8 until the limiting rod 9 disengages from the first connecting rod 6. The operator holds the outer support rod 1 and the inner support rod 2 with both hands and applies force inward to rotate them. At this time, the outer support rod 1 and the inner support rod 2 rotate relative to each other, causing the support foot 5 to rotate from a horizontal support state to a storage state that fits snugly against the rod body. During the rotation, the components of the limiting component move in opposite directions, and the limiting plate 8, the limiting rod 9, etc., are reset under the action of the connecting rod until the outer support rod 1 and the inner support rod 2 are completely folded and snug, completing the folding of the display panel, effectively reducing the space occupied by the display panel, and facilitating transportation and storage.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
