[0006] As a preferred technical solution of the present invention, the lower guide rail and the upper guide rail are in an arc-shaped structure with the slider, and the arcs of the lower guide rail and the upper guide rail are the same and are both 120-160 degrees.

[0007] By adopting the above technical solution, the arc angles of the lower guide rail, the upper guide rail and the slider are the same, ensuring that the warning sign body moves in an arc shape on the lower guide rail and the upper guide rail with the help of the slider, and the wind resistance of the warning sign is reduced by using the change in angle.

[0008] As a preferred technical solution of the present invention, the center points of the lower guide rail and the upper guide rail are located on the same horizontal line as the center point of the rotating shaft.

[0009] By adopting the above technical solution, the warning sign body is guided by the rotating shaft to ensure the stability of the arc movement, and is supported by the lower guide rail and the upper guide rail in conjunction with the slider to ensure the uniformity of the force on the supporting structure.

[0010] As a preferred technical solution of the present invention, the brackets are symmetrically distributed at the left and right ends of the base frame.

[0011] By adopting the above technical solution, there is a certain distance between the upper guide rail and the top surface of the base frame, ensuring that the travel route of the warning sign body will not be blocked and facilitating airflow to pass through. At the same time, there is a certain angle between the bracket and the base frame to ensure that it will not fall over when the wind is too strong.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the warning sign for municipal engineering construction:

[0013] Reduce wind resistance: The slider moves along the arc of the lower and upper rails to tilt the warning sign, effectively reducing wind resistance, improving the stability of the warning sign under wind, reducing the risk of displacement caused by wind, and improving nighttime clarity: The nickel-hydrogen battery powers the light strip, enhancing the visibility of the warning sign at night, improving the safety of the construction area, reducing the occurrence of traffic accidents, and increasing the stability of the warning sign: Through the rotation of the shaft and the bracket, and the sliding of the slider and the lower and upper rails, the warning sign can flexibly adjust its posture under the action of wind, ensuring its stability under various weather conditions, and improving the reset function of the warning sign: When the wind is small, the warning sign can remain upright. When the wind is strong, the slider moves along the arc of the lower and upper rails to tilt the warning sign, reducing wind resistance. When the wind decreases, the warning sign can automatically reset to its normal posture with the help of gravity. BRIEF DESCRIPTION OF THE DRAWINGS
