[0027] Regarding the folding frame:

[0028] The folding frame includes a connecting plate 3 and support legs 1 arranged at both ends of the connecting plate 3. The upper ends of the support legs 1 are rotatably connected to the connecting plate 3, and the lower ends of the support legs 1 are provided with feet 2, and the feet 2 are rotatably connected to the support legs 1;

[0029] On one side of the outrigger 1 facing the indicator board 4, there is an angle adjustment bracket. The angle adjustment bracket is rotatably connected to the outrigger 1 and detachably connected to the indicator board 4. The angles between the outrigger 1 and the foot 2, and between the outrigger 1 and the connecting plate 3 can all be adjusted. By adjusting the angles of each component, it is ensured that the frame can be placed on different road surfaces or slopes. The angle adjustment bracket is arranged between the outrigger 1 and the indicator board 4 and is used to adjust the display angle of the indicator board 4 so that the indicator board 4 maintains a state parallel to the line of sight, improving the display effect of the indicator board 4.

[0030] A positioning component for locking the angle adjustment bracket is provided between the angle adjustment bracket and the outrigger 1. The positioning component locks the angle adjustment bracket, so that the indicator board 4 will not deflect during the display process, and the stability is better.

[0031] For the specific structure of the angle adjustment bracket, please refer to the following description:

[0032] The angle adjustment bracket includes a first hinge seat 6 and an adjustment plate 7. The first hinge seat 6 is fixedly connected to the lower end of the outrigger 1. The lower end of the adjustment plate 7 is rotatably connected to the first hinge seat 6 through a second hinge seat 17. The positioning component is placed between the adjustment plate 7 and the outrigger 1. The side of the adjustment plate 7 away from the positioning group is detachably connected to the indicator board 4. The detachable connection method facilitates the staff to replace the indicator board 4.

[0033] The indicator board 4 is fixed to the adjustment plate 7. When the two outriggers 1 are opened, the display surface of the indicator board 4 will tilt upward. Rotate the adjustment plate 7 to adjust the display angle of the indicator board 4 so that it is parallel to the field of vision of passing pedestrians, and then lock the adjustment plate 7 through the positioning component.

[0034] Regarding the positioning component:

[0035] The positioning component includes a diagonal support plate 8. One end of the diagonal support plate 8 is rotatably connected to the upper end of the adjustment plate 7. The other end of the diagonal support plate 8 is inserted into a slot 10 opened on the side of the outrigger 1. The slot 10 is slidably connected to the diagonal support plate 8. A number of first positioning holes 9 are opened on the diagonal support plate 8, and each diagonal support plate 8 is evenly arranged along the length direction of the first positioning holes 9. A bolt fixing part matching with the first positioning holes 9 is provided on the outrigger 1.

[0036] The usage method of the positioning component is as follows:

[0037] After adjusting the angle between the outrigger 1 and the adjustment plate 7, rotate the diagonal support plate 8 to open the diagonal support plate 8. The diagonal support plate 8 will slide along the slot 10. After aligning one of the first positioning holes 9 on the outside of the diagonal support plate 8 with the bolt fixing part assembled on the outrigger 1, assemble the bolt fixing part therein. After the diagonal support plate 8 is fixed, it can limit the adjustment plate 7 from continuing to rotate. The triangular frame formed by the adjustment plate 7, the outrigger 1 and the diagonal support plate 8 has good stability and can effectively improve the impact resistance of the indicator board 4.

[0038] It should be further noted that the bolt fixing member includes a fixing bolt 12, and the fixing bolt 12 is in threaded connection with a second positioning hole 11 opened on the outer side of the support leg 1. There are a plurality of second positioning holes 11 on the outer side of the support leg 1, and the respective second positioning holes 11 are uniformly arranged along the length direction of the support leg 1. The second positioning hole 11 communicates with the slot 10.

[0039] When fixing the diagonal bracing plate 8, after screwing the fixing bolt 12 into the corresponding second positioning hole 11, it can be then screwed into the corresponding first positioning hole 9. A plurality of second positioning holes 11 are also opened on the support leg 1 to change the installation position of the fixing bolt 12, thereby increasing the flexibility of the position adjustment of the diagonal bracing plate 8.

[0040] In a relatively good embodiment, a groove 5 is opened on the upper end surface of the foot 2, and a plurality of bolt holes 16 are provided in the groove 5, and the bolt holes 16 penetrate the foot 2 up and down. The staff can directly fix the foot 2 through the fixing bolt, and the groove 5 opened on the foot 2 is used to place a counterweight or a pressing plate for limiting, further improving the firmness of the foot 2.

[0041] Regarding the fixation between the indicator board 4 and the adjustment board 7: At least one hook 14 is provided on the side of the adjustment board 7 facing the indicator board 4. The hook 14 is fixedly connected to the adjustment board 7, and the hook 14 is engaged with a buckle 15 provided on the indicator board 4. The buckle 15 is fixedly connected to the indicator board 4. The indicator board 4 adopts a scheme of being fixed by a hook and is hung on two juxtaposed adjustment boards 7. When removing the indicator board 4 from the adjustment board 7, the indicator board 4 can be lifted upward. The replacement and disassembly are convenient.

[0042] In order to prevent the support leg 1 and the connection plate 3, the adjustment board 7 and the support leg 1, and the support leg 1 and the foot 2 from rotating due to shaking after being opened, a butterfly spring for increasing the damping at the connection is provided at the connection between the foot 2 and the support leg 1, the connection between the connection plate 3 and the support leg 1, and the connection between the second hinge seat 17 and the first hinge seat 6. By increasing the damping at the rotation of each movable part through the butterfly spring, each movable component will not rotate arbitrarily after the adjustment is completed.

[0043] The working principle of this application:

[0044] The angles between the support leg 1 and the foot 2, and between the support leg 1 and the connection plate 3 can both be adjusted. By adjusting the angles of each component, it is ensured that the frame can be placed on different road surfaces or slopes. The angle adjustment bracket is provided between the support leg 1 and the indicator board 4 and is used to adjust the display angle of the indicator board 4 so that the indicator board 4 maintains a state parallel to the line of sight, improving the display effect of the indicator board 4.
