[0004] However, while this type of power sign can be adjusted to multiple angles and heights, the rollers often come into direct contact with the ground when the sign is moved. This results in poor automatic correction and buffering when the rollers move on different surfaces, affecting their lifespan and reducing the ease of moving the power sign.

[0005] Therefore, in view of this, we studied and improved the existing structure to propose a portable power sign. Utility Model Content

[0022] 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.

[0023] Example 1:

[0024] like Figures 1-4 As shown, a movable power sign includes a movable base 1. A support rod 2 is fixedly connected to the outer wall of the movable base 1. A sign body 3 is fixedly connected to the top of the support rod 2. A threaded rod 4 is rotatably connected to the outer wall of the movable base 1. A knob 5 is fixedly connected to one end of the threaded rod 4. A lifting rod 6, which is slidably connected to the outer wall of the movable base 1, is threadedly connected to the outer wall of the threaded rod 4. A universal roller frame 8 is rotatably connected to the bottom of the lifting rod 6. A rotating rod 12 is fixedly connected to the rotation center of the universal roller frame 8 via a rotating shaft. A lifting rod 12 is rotatably connected to the outer wall of the rotating rod 12. The damper body 13 is rotatably connected to the outer wall of the rod 6. One end of the rotating rod 12 is fixedly connected to a sliding column 14 that is slidably connected to the outer wall of the lifting rod 6. When the power sign is moved to a warning position, in order to improve the automatic correction effect of the roller on different bumpy terrains, the rotating rod 12 will rotate when the roller contacts the ground. The rotation of the rotating rod 12 will cause the sliding column 14 to slide in an arc along the inner wall of the arc groove 15. At the same time, the squeezing angle of the damper body 13 will be adjusted to achieve the effect of adapting the roller to different ground surfaces.

[0025] like Figure 3 As shown, an arc-shaped groove 15 is provided at the connection between the outer wall of the lifting rod 6 and the sliding column 14, which is beneficial to achieve the effect of limiting the sliding of the sliding column 14 through the opening of the arc-shaped groove 15.

[0026] like Figure 2As shown, a connecting groove 7 is provided at the connection point between the outer wall of the movable seat 1 and the lifting rod 6, which facilitates the convenient storage of the universal roller frame 8 when not in use.

[0027] like Figure 2 As shown, the inner wall contour of the connecting groove 7 is larger than the outer wall contour of the universal roller frame 8. This design, which makes it easier to store the universal roller frame 8, is beneficial.

[0028] like Figure 4 As shown, the outer wall of the movable base 1 is threaded with a screw 9, and the outer wall of the screw 9 is provided with an outer helix 10. The inner wall of the movable base 1 and the connection part of the outer helix 10 are provided with an inner helix 11. This facilitates the stable insertion of the signboard on the soft ground by means of the screw 9 threaded on the outer wall of the movable base 1.

[0029] like Figure 2 As shown, there are four sets of screws 9, and the positions of the four sets of screws 9 are distributed around the movable base 1. This arrangement helps to improve the stability of the signboard.

[0030] like Figure 3 As shown, there are two sets of damper bodies 13. The positions of the two sets of damper bodies 13 are symmetrical about the central axis of the rotating rod 12. This is beneficial to achieve the effect of adaptive correction of the universal roller frame 8 by setting two sets of damper bodies 13 with their positions symmetrical about the central axis of the rotating rod 12.

[0031] Working principle: When using this type of movable power sign, in order to improve the automatic correction effect of the roller on different bumpy terrains when moving the power sign to a warning position, the roller will drive the rotating rod 12 to rotate when it contacts the ground. The rotation of the rotating rod 12 will drive the sliding column 14 to slide in an arc shape along the inner wall of the arc groove 15. At the same time, the pressing angle of the damper body 13 will be adjusted to achieve the effect of adapting the roller to different ground contact.
