Self-adaptive road surface deceleration strip

Abstract

The invention provides a self-adaptive road surface deceleration strip. The self-adaptive road surface deceleration strip comprises a base located below a road surface and a deceleration strip locatedat an opening of the road surface, wherein a horizontal limiting shaft is hinged to one end of the deceleration strip, the other end is provided with pawl iron, a horizontal guide plate and a horizontal limiting plate are arranged on the base, one end of the horizontal limiting shaft is slidably connected to the horizontal guide plate, the other end is slidably connected to the horizontal limiting plate, a horizontal spring check ring is arranged on the horizontal limiting shaft, a horizontal spring is arranged on the horizontal limiting shaft, a horizontal limiting locking nut is arranged onthe horizontal limiting shaft, a vertical limiting shaft is hinged to the middle of the deceleration strip, a vertical direction limiting plate is arranged on the base, a horizontal oblong hole is formed in the vertical direction limiting plate, and the vertical limiting shaft is inserted into the horizontal oblong hole, a vertical spring check ring is arranged in the middle of the vertical limiting shaft, a vertical spring is arranged on the vertical limiting shaft, and a vertical limiting locking nut is arranged at the end, which is away from the deceleration strip, of the vertical limitingshaft. The self-adaptive road surface deceleration strip provided by the invention is good in adaption effect.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to an adaptive road speed bump. Background technique [0002] There are many pedestrians passing by in the entrance areas of schools, hospitals, and residential areas. In order to ensure traffic safety, speed bumps are often set up on the corresponding roads in those areas to remind vehicles to pass at a speed limit. The simple speed bumps currently installed have almost the same appearance, fixing form and use effect, and the existing problems are basically the same. The first problem is that redundant reminders are issued to speed limit and law-abiding vehicles, which make the vehicles pass through bumps, which affects the ride comfort of the vehicles. Vehicles that obey the traffic rules have not been treated humanely; The production is still made of cast iron, and it must be fixed to the road surface with spikes. During use, the speed bump is subjected to frequent im...

AI Technical Summary

Problems solved by technology

The first problem is that redundant reminders are issued to speed limit and law-abiding vehicles, which make the vehicles pass through bumps, which affects the ride comfort of the vehicles. Vehicles that obey the traffic rules have not been treated humanely; The production is still made of cast iron, and it must be fixed to the road surface with spikes. During use, the speed bump is subjected to frequent impacts from the wheels. Obviously, this kind of fixing is not reliable, and the speed bump will loosen in a short time. ; The third problem is that the service life of the speed bump made of modified rubber is really limited, which increases the cost of maintenance and replacement

In short, the use effect and maintenance process of the simple speed bumps are not ideal, and the bump reminders for illegal speeding vehicles are not strong enough
