Description

Technical field:

[0001] The utility model relates to the technical field of road safety facilities, in particular to a road speed bump. Background technology:

[0002] Speed ​​bumps, also called speed reduction ridges, are traffic facilities installed on urban roads to slow down passing vehicles. They are usually strip-shaped or dot-shaped; they are mainly made of rubber, but also metal; they are usually yellow and black to attract visual attention, and slightly bulge the road surface to achieve the purpose of slowing down vehicles.

[0003] In the current existing technology, bolts are usually used to directly fix the arc-shaped speed bumps on the road. The structure is relatively simple and lacks a buffer structure. When a vehicle passes over the speed bump, it will cause a certain impact on the vehicle, reducing the comfort of the driving vehicle. In addition, the speed bump will be partially damaged after long-term use. Since the speed bump cannot be partially removed, it is usually replaced as a whole, which increases the purchase cost. Therefore, it is necessary to design a road speed bump that can solve the above problems. Utility model content:
