When the driver and passengers encounter a situation where the human eye cannot distinguish the height limit in rainy and foggy weather or the speed is too fast to distinguish, they can safely drive the vehicle through the height limit pole first. When the vehicle hits the height limit plate, the height limit plate can be rotated through the first column. After the vehicle passes, the height limit plate is pulled back to a normal state by the tension of the spring. At the same time, after the height limit plate is knocked open, the two induction plates are separated, and the alarm sounds an alarm to remind the driver that the vehicle is too high, and the driver re-plans the route to avoid the vehicle continuing to move forward and affecting traffic.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned municipal road height limit pole has the following problems: since the spring is pulled at a certain angle during the rotation of the height limit plate, friction between the spring and the waterproof cylinder will reduce the service life. At the same time, the spring resets the height limit plate and causes it to hit the waterproof cylinder. Based on this, the utility model designs a road height limit pole for municipal construction to solve the above problems. Utility Model Content
