[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] See Figs. 1-3 This application proposes a portable road construction warning sign to address the shortcomings of traditional warning signs, such as their large size, difficulty in transportation, and poor warning effect at night or in inclement weather, which can easily lead to safety accidents. The sign features a flexible material surface coated with a highly reflective paint, combined with LED warning lights, providing good warning even at night or in inclement weather. Equipped with a solar charging panel, it can use solar energy to power the warning lights, eliminating the need for an external power source, thus saving energy and being environmentally friendly. Furthermore, the bottom of the folding bracket has anti-slip rubber pads to ensure stable placement on various surfaces, improving safety. The foldable design makes it small, lightweight, and easy to carry and transport, suitable for use in various construction sites.

[0022] Specifically, a portable road construction warning sign includes a warning surface 1, a folding bracket 2, a warning light 3, and a solar charging panel 4. The folding bracket 2 includes a telescopic rod 21 and a connector 22. The telescopic rod 21 includes a large sleeve rod 211 and a small sleeve rod 212. The small sleeve rod 212 is embedded in the large sleeve rod 211. The large sleeve rod 211 has multiple locking holes 7, which can be used to adjust the height of the warning sign as needed. The small sleeve rod 212 has buckles 6 for easy and quick unfolding and storage. When unfolded, it can stand the folding bracket 2 upright, keeping it stable and vertical. For easy observation by pedestrians and passing vehicles, the small sleeve 212 can be tucked into the large sleeve 211 by pressing down the buckle 6 when stored to reduce its size, making it convenient to carry and transport. The solar charging panel 4 is installed on the upper part of the folding bracket 2 via the connector 22. The warning surface 1 is installed on the folding bracket 2 below the solar charging panel 4. The surface of the solar charging panel 4 is covered with a waterproof coating, which allows the solar charging panel 4 to work normally in inclement weather. The solar charging panel 4 can provide a continuous power supply for the warning light 3, and can be used normally even in construction sites without power.

[0023] The warning surface 1 is made of a foldable flexible material, which can be adapted to different construction site requirements. The surface of the warning surface 1 is coated with a high-reflective paint 8, which can reflect light in low-light environments, so that the warning sign can be seen by passing vehicles and pedestrians from a distance, improving the warning effect and reducing the risk of accidents. Conspicuous warning signs can also be designed and printed on the warning surface 1 according to specific circumstances to clearly inform surrounding personnel and vehicles that road construction is underway in the area, reminding them to slow down in advance and pay attention to avoid the area, thus ensuring the safety of construction workers and passers-by.

[0024] The warning light 3 is mounted on top of the folding bracket 2 via connector 22. The solar charging panel 4 is electrically connected to the warning light 3. The warning light 3 uses LED beads, which are characterized by high brightness and low energy consumption. The high brightness of the light can emit a strong light signal at night or in low-light environments, attracting the attention of passing vehicles and pedestrians and playing a clear warning role. The low energy consumption allows the warning light to work continuously for a long time with limited battery power, reducing the charging frequency and improving ease of use. The flashing mode can also be switched through the built-in microcontroller of the warning light 3, so that the warning light 3 has multiple flashing modes and colors to choose from. Different flashing modes can be used in different construction scenarios or weather conditions to achieve the best warning effect. For example, in foggy weather with low visibility, a fast flashing mode can be used to attract the driver's attention more strongly. In normal conditions at night, a slow flashing mode can be used, which can play a warning role without causing excessive interference to the driver. It can be adjusted according to different construction needs to improve the applicability of the warning sign. The bottom of the folding bracket 2 is equipped with an anti-slip rubber pad 5, which increases the friction between the folding bracket 2 and the ground, preventing the warning sign from sliding or tipping over when there is wind or vibration caused by passing vehicles. This ensures that it can be placed stably on different ground surfaces, improves the stability of the warning sign, and thus ensures the continued effectiveness of its warning function.

[0025] As can be seen from the above technical solution, when using a portable road construction warning sign, construction workers unfold the folding bracket 2. The telescopic rod 21 of the folding bracket 2 facilitates quick unfolding and storage. When unfolded, the folding bracket 2 stands upright, keeping it stable and easy for pedestrians and passing vehicles to see. When stored, pressing down the buckle 6 allows the small sleeve rod 212 to be tucked into the large sleeve rod 211 to reduce the volume, making it easy to carry and transport. The anti-slip rubber pad 5 at the bottom prevents the warning sign from sliding or tipping over when there is wind or vibration from passing vehicles, ensuring that it can be placed stably on different surfaces, improving the stability of the warning sign, and making it more visible during the day. The solar charging panel 4 absorbs solar energy and charges the built-in battery. At night or in low light, the warning light 3 automatically turns on. The high-brightness light of the LED beads can emit a strong light signal at night or in low light environments, attracting the attention of passing vehicles and pedestrians and playing a clear warning role. The surface of the warning surface 1 is coated with a highly reflective paint 8, which can reflect light in low light environments, so that the warning sign can be seen by passing vehicles and pedestrians from a distance, improving the warning effect and reducing the risk of accidents. After construction, the warning light 3 is turned off and the folding bracket 2 is stored for easy carrying and storage.
