[0002] The warning units on highways are key facilities to ensure road safety, improve driver alertness and driving smoothness. The highway merging warning unit refers to the prompt that the ramp ahead will merge into the main road, while the highway exit warning unit refers to the prompt to leave the main road from the ramp ahead, enter the ramp and leave the highway, so the warning unit is an indispensable sign on highways.

[0003] The warning unit of the existing highway is basically composed of a warning sign and a mounting frame. The warning sign is installed on the mounting frame by multiple screws. The mounting frame is installed on one side of the highway to provide road prompts to drivers passing by. After the warning unit has been used for a certain period of time, the surface of the warning sign will be worn. This situation can easily lead to the driver being unable to clearly identify the instructions on the warning sign in time. Therefore, the staff will regularly replace the worn warning signs. The staff will use tools to remove multiple screws in turn before they can remove the warning signs for replacement. This situation makes the disassembly process of the existing warning signs more cumbersome and increases the labor intensity of the staff to a certain extent.

[0004] Therefore, it is necessary to provide a new highway merging and exit warning unit to solve the above technical problems. Utility Model Content
