[0028] On the basis of the above structure, the bottom support assembly 4 includes a vertical shaft 41, a worm gear 42, large conical teeth 43, a lower support rod 44 and a bottom hook 45. The vertical shaft 41 is connected to the bearing of the first bracket 3. The middle outer side of the vertical shaft 41 is fixedly sleeved with a worm gear 42. The top of the vertical shaft 41 is fixedly connected with a large conical tooth 43. The outer wall of the worm gear 42 is fixedly connected with a lower support rod 44. The bottom hook 45 is fixedly connected to the upper end of the lower support rod 44 away from the worm gear 42.

[0029] In this embodiment, by using the large conical teeth 43, the bottom support assembly 4 and the inner rod 7 can be linked to each other, which is convenient for the unfolding and folding of the device, and can reduce the size of the device to achieve the technical purpose of easy portability.

[0030] On the basis of the above structure, the two worm wheels 42 are respectively located at the front and rear sides of the worm 2 and are meshed with the worm 2 , and the rotation directions of the two lower support rods 44 are always opposite to each other.

[0031] In this embodiment, when the worm 2 is rotated manually, the two worm wheels 42 can respectively drive the two lower support rods 44 to rotate synchronously in opposite directions.

[0032] Based on the above structure, the small conical tooth 6 is located between the two large conical teeth 43, and the small conical tooth 6 is meshingly connected with the two large conical teeth 43. The diameters of the two large conical teeth 43 are equal, and the diameter length of the small conical tooth 6 is only half of the diameter length of the large conical tooth 43.

[0033] In this embodiment, the small conical teeth 6 meshed between the two large conical teeth 43 facilitate the inner rod 7, the outer rod 8 and the top support assembly 9 to automatically rotate and lift upward when controlling the rotation and expansion of the bottom support assembly 4, making the operation and adjustment of the device more convenient.

[0034] Based on the above structure, the top support assembly 9 includes a third bracket 91, an upper support rod 92, an upper hook 93 and a positioning bolt 94. The third bracket 91 is welded and fixed to the outer wall of the right end of the outer rod 8. The upper support rod 92 is rotatably installed on the inner side of the third bracket 91. The upper end of the third bracket 91 is installed with a positioning bolt 94, and the upper support rod 92 is fixedly connected to the upper hook 93 at one end away from the third bracket 91.

[0035] In this embodiment, the positioning bolt 94 is provided to facilitate positioning of the upper support rod 92 that is rotated and opened, and the upper hook 93 is used to facilitate stably supporting and unfolding the poster.

[0036] On the basis of the above structure, the threaded rod 10 is connected to the inner rod 7 by threaded connection. The longitudinal sections of the inner rod 7 and the outer rod 8 are both square structures. The outer rod 8 is slidably sleeved on the outer side of the inner rod 7.

[0037] In this embodiment, the threaded rod 10 is rotated to drive the outer rod 8 to slide and adjust on the outside of the inner rod 7. By adjusting the relative positions of the inner rod 7 and the outer rod 8, posters of different lengths can be stably supported and unfolded, thereby enhancing the practicality of the device.

[0038] The working principle of the utility model is as follows:

[0039] When in use, first manually rotate the worm 2 whose bearing is installed in the middle of the counterweight base 1. Under the action of the two worm wheels 42, the two groups of bottom support components 4 can be controlled to rotate and open synchronously in the direction away from each other. When the large conical teeth 43 are driven to rotate by the vertical shaft 41, the small conical teeth 6 meshing with the large conical teeth 43 can also drive the inner rod 7, the outer rod 8 and the top support component 9 to rotate and lift upward, so that the device can be lifted by Figure 1 The state shown changes to Figure 5In the state shown, and because the diameter length of the small conical teeth 6 is only half of the diameter length of the large conical teeth 43, the rotation angle of the lower support rod 44 is half of the rotation angle of the inner rod 7, and the device can be fully opened, and then the upper support rod 92 is rotated to a state relatively vertical with the outer rod 8, and then the positioning bolt 94 is used to position the upper support rod 92, and finally the bottom hook 45 and the upper hook 93 are used to conveniently hook the poster and open it for display. Similarly, the device can also be fully folded to achieve a significant reduction in the size of the device, and the overall structure of the device is simple, the weight is lighter, and it is easy to carry and transfer, which is more in line with the actual use requirements of outdoor promotional packaging;

[0040] When the device is in use, the threaded rod 10 can also be manually rotated to drive the outer rod 8 connected to its bearing to slide and adjust on the outside of the inner rod 7. By controlling the relative position of the outer rod 8 on the outside of the inner rod 7, it is convenient to adapt to posters of different lengths and sizes for stable support. Moreover, when the outer rod 8 slides, the distance between the bottom hook 45 and the upper hook 93 can be increased, which is convenient for applying tension to both ends of the poster, making it easier to fully prop up and unfold the poster, avoiding wrinkles on the poster, and facilitating the full display of the poster content.

[0041] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
