speed bump for road

Abstract

The invention provides a deceleration belt for roads, and relates to the field of road deceleration belts. The road speed bump includes a base and a speed bump body, the left end of the base is hinged to the left end of the speed bump body, a torsion spring is installed at the hinge between the base and the speed bump body, and a seal is fixed on the right side of the speed bump body. The soft plate A and the front and rear sides of the speed bump body are fixedly installed with a sealed soft plate B. When the road deceleration belt passes through the car to crush the deceleration belt body, the deceleration belt body will swing downwards, and the deceleration belt body can drive two arc-shaped tooth plates to mesh with the gears when the deceleration belt body swings. At this time, the deceleration belt body can be lowered to be flush with the base , make the vehicle pass smoothly, achieve the effect of restricting the speeding vehicle, and play the effect of stably passing the vehicle running at a safe speed, and solve the problem that the vibration of the speed reduction belt in the prior art is relatively large when it is in contact with the vehicle, causing the vehicle to There are certain dangers in passing.

Description

technical field [0001] The invention relates to the field of road deceleration belts, in particular to a road deceleration belt. Background technique [0002] Speed ​​bumps are also called speed bumps, which are traffic facilities installed on the road to slow down passing vehicles. They are generally strip-shaped or dot-shaped, and the material is mainly rubber or metal. Generally, they are yellow and black to cause visual acuity. Note that the road surface is slightly arched to achieve the purpose of vehicle deceleration. It is generally set at highway crossings, industrial and mining enterprises, schools, residential quarter entrances, etc., where vehicles need to slow down and road sections that are prone to traffic accidents. New traffic-specific safety settings for non-motorized vehicle speeds. The speed bump has greatly reduced the occurrence of accidents at major traffic intersections, and is a new type of special facility for traffic safety. The vehicle is not onl...

AI Technical Summary

Problems solved by technology

[0003] The structure of the current speed bumps is very single. When the speed bumps are in contact with the vehicle, they vibrate greatly, which leads to a certain degree of danger when the vehicle passes. If the vehicle keeps driving at a limited safe speed, it will still be affected by the speed bumps. The settings are not reasonable enough, and a lot of resources are not utilized
