[0036] A reflective film 6 is fixedly connected to the outer surface of the support rod 1.

[0037] Specifically, support rod 1 serves as the supporting structure for the entire device, providing a mounting base for other components. Adjustment component 2 is driven by motor 201, whose output drives threaded rod 202 to rotate. This causes the lifting block 204 on the outer surface of threaded rod 202 to move up and down with the rotation of threaded rod 202, thereby pushing extension rod 203 up or down to adjust the height of warning sign 3 to adapt to different warning needs and expand the warning coverage area. The warning sign 3 fixed externally to adjustment component 2 is used to display warning information and is one of the core components of the warning device. When adjustment component 2 is running, the fixing ring 205 at the upper end of the outer surface of extension rod 203 drives the warning sign 3 to rise and fall synchronously. Simultaneously, the spring 206 on the outside of threaded rod 202 acts as a buffer and auxiliary support, making the adjustment process smoother and preventing damage to components due to vibration or sudden force. The reflective film 6 fixed to the outer surface of support rod 1 reflects light when illuminated, enhancing the warning effect. Even at night or in low-light conditions, it can attract the attention of pedestrians and vehicles, further ensuring road safety.

A placement plate 402 is fixedly connected to the outer surface of the extension rod 203, and a fan 403 is fixedly connected to the upper surface of the placement plate 402. The input end of the fan 403 is connected to the outside, and an air supply pipe 404 is connected between the output end of the fan 403 and the outer surface of the airbag 401.

[0039] The placement plate 402 is located below the fixing ring 205.

[0040] Warning lights 5 are fixedly connected to the outer surfaces of the airbag 401 and the warning sign 3.

[0041] A filter screen cover 405 is fixedly connected to the upper surface of the placement plate 402, and the filter screen cover 405 covers the outside of the fan 403.

[0042] A protective net 7 is fixedly connected to the side surface of the warning sign 3. The protective net 7 wraps around the outside of the airbag 401. On the outer surface of the airbag 401, warning lights 5 are distributed in the gaps of the protective net 7.

[0043] Specifically, in the expansion assembly 4, when the blower 403 is started, air is inflated into the airbag 401 through the air supply pipe 404, causing the airbag 401 to expand and increasing the warning area of ​​the warning sign 3, thereby enhancing the warning effect; the placement plate 402 is used to install the blower 403, providing stable support for the blower 403 and ensuring that the blower 403 can work normally; the blower 403 is used to draw in outside air, pressurize it, and deliver it into the airbag 401, realizing the inflation and expansion of the airbag 401; the warning light 5 fixed to the outer surface of the airbag 401 and the warning sign 3 illuminates at night or in low-light environments, attracting pedestrians and vehicles by flashing or remaining constantly lit. To enhance the warning effect, the filter screen 405 fixed on the upper surface of the placement plate 402 covers the outside of the fan 403, effectively blocking external dust and debris from entering the fan 403, preventing damage to the fan 403 due to the intake of impurities, extending the service life of the fan 403, and ensuring its stable operation. The protective net 7 fixed on the side surface of the warning sign 3 wraps around the airbag 401, protecting the airbag 401 from damage caused by external impact. At the same time, the warning lights 5 are distributed in the gaps of the protective net 7, which does not affect the lighting effect of the warning lights 5, and can also improve the overall safety and stability of the device with the help of the protective net 7.
