[0027] Please see Figures 1-5 This utility model provides a technical solution: a portable billboard base, comprising:

[0028] The advertising base 1 has two adjustment slots 5 on its top and four casters fixedly installed on its bottom.

[0029] The base support structure is located on the advertising base 1;

[0030] The base support structure includes two slide rods 12, a sliding seat 14, two connecting plates 6, and a support base 7. The two slide rods 12 are fixedly connected inside the corresponding adjustment grooves 5. The sliding seat 14 is slidably connected to the outer surface of the two slide rods 12 and is slidably connected inside the corresponding adjustment grooves 5. One end of each of the two connecting plates 6 is rotatably connected inside the support base 7. The ends of the two connecting plates 6 away from the support base 7 are rotatably connected to the sliding seat 14 and the corresponding adjustment grooves 5, respectively.

[0031] The base support structure also includes a fixed plate 15, a second pin 11, and a second spring 16. The fixed plate 15 is fixedly connected to the top of the sliding seat 14. The second pin 11 is slidably connected inside the fixed plate 15. The second spring 16 is sleeved on the outer surface of the second pin 11. One end of the second spring 16 is fixedly connected to the fixed plate 15, and the end of the second spring 16 away from the fixed plate 15 is fixedly connected to the second pin 11. Two second insertion holes 3 are opened on one side of the advertising base 1, which communicate with the interior of the corresponding adjustment groove 5. The end of the second pin 11 away from the second spring 16 is inserted into the corresponding second insertion hole 3. There are two base support structures, and both base support structures are set inside the corresponding adjustment groove 5.

[0032] The advertising base 1 has a storage slot 13 on one side. A lifting plate 10 is slidably connected inside the storage slot 13. Multiple first insertion holes 17 are opened at the bottom of the lifting plate 10. A first pin 8 is slidably connected to the bottom of the advertising base 1. One end of the first pin 8 extends slidably into the storage slot 13 and is inserted into the corresponding first insertion hole 17. A first spring 9 is sleeved on the outer surface of the first pin 8. One end of the first spring 9 is fixedly connected to the advertising base 1, and the end of the first spring 9 away from the advertising base 1 is fixedly connected to the first pin 8.

[0033] The bottom wall of the advertising base 1 is fixedly connected to a lower clamping plate 2, the top of the lifting plate 10 is fixedly connected to an upper clamping plate 18, a handle is provided on the upper clamping plate 18, and a pressure plate 4 is rotatably connected to the inner wall of the advertising base 1.

[0034] Furthermore, when using this device, during the installation of the billboard, the operator pulls the second pin 11. The movement of the second pin 11 stretches the corresponding second spring 16. After the second pin 11 disengages from the corresponding second insertion hole 3, the operator then drags the sliding seat 14 horizontally under the guidance of the two sliding rods 12. The movement of the sliding seat 14 causes the connecting plate 6 on it to move and rotate. Under the rotational connection between the two connecting plates 6 and the support base 7, the movement of the connecting plate 6 on the sliding seat 14, guided by the other connecting plate 6, causes the support base 7 to move downward, thus facilitating contact with the ground. This allows the second pin 11 to be inserted into the second insertion hole 3 near the lower clamping plate 2. This facilitates the fixing of the support base 7. The two base support structures work on the same principle. By pulling the first pin 8, the first pin 8 moves and stretches the first spring 9. When the first pin 8 disengages from the corresponding first socket 17, the lifting plate 10 is pulled by the operator, so that the lifting plate 10 can be adjusted according to the width of the advertising board. After the adjustment is completed, the first pin 8 is released, and the first pin 8 will reset under the action of the first spring 9 and be inserted into the corresponding first socket 17. At the same time, the advertising base 1 can also be flipped so that the side of the advertising base 1 closest to the pressure plate 4 contacts the ground. Then, the pressure plate 4 is rotated 180 degrees to the upper clamp and the counterweight is used to press the pressure plate 4 down, so that it can be used for advertising boards of different specifications.

[0035] With the cooperation of two connecting plates 6, support base 7, slide rod 12, sliding seat 14, fixing plate 15, second spring 16 and second pin 11, the sliding seat 14 can move and drive the support base 7 to move downward and contact the ground under the rotational connection of the two connecting plates 6 and support base 7, thereby increasing the contact area between the advertising base 1 and the ground. With the second pin 11 and the two second holes 3 inserted, it is easy to limit and fix the sliding seat 14 after it moves, which further improves the stability of the advertising base 1 during use.

[0036] Working principle: When installing the billboard, the operator pulls the second pin 11. The movement of the second pin 11 stretches the corresponding second spring 16. After the second pin 11 disengages from the corresponding second insertion hole 3, the operator then drags the sliding seat 14 horizontally under the guidance of the two sliding rods 12. The movement of the sliding seat 14 causes the connecting plate 6 on it to move and rotate. With the rotational connection between the two connecting plates 6 and the support seat 7, the sliding seat 14 moves the connecting plate 6 on it, which in turn causes the support seat 7 to move downward under the guidance of the other connecting plate 6, thus facilitating contact with the ground. At this time, the second pin 11 can be inserted into the second insertion hole 3 near the lower clamping plate 2, thereby facilitating the fixation of the support seat 7. The working principle of the two base support structures is the same.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
