[0002] In road construction, traditional warning signs are usually made of metal or plastic and printed with relevant warning messages, such as "Construction Area, Please Drive with Caution" or "Road Closed Ahead," to remind passing vehicles and pedestrians to pay attention to safety. Warning signs are usually fixed to the roadside or hung in the air with brackets to ensure they are conspicuous and visible.

[0003] After searching, in order to solve the problem that the warning sign is small in size and cannot be changed, thereby affecting the effect of seeing the warning sign from a distance and further affecting the warning effect, a temporary road warning sign that is easy to assemble and disassemble is disclosed in Publication No. CN221072365U. The temporary road warning sign that is easy to assemble and disassemble can be taken out of the movable groove by pulling the second warning plate upward, which can increase the display area of ​​the temporary road warning sign and improve the warning effect. The tightening screw can fix the second warning plate, which can improve the stability of the second warning plate, which is conducive to the use of the temporary road warning sign. The operation is simple and convenient to assemble and use. At the same time, the first warning plate and the second warning plate can be fixed in the installation groove by the limit pin. The temporary road warning sign can be folded and retracted, which is simple to operate and convenient to disassemble and carry.

[0004] Existing warning signs are basically fixed as a whole. During the road construction process, it is inconvenient to store them, resulting in the warning signs being too large in size. This makes it inconvenient to transport them, occupies space during transportation, and is inconvenient to use.

[0005] For this reason, a kind of road engineering warning sign is proposed. Utility Model Content
