Telescopic deceleration strip for toll road

Abstract

The invention discloses a toll road telescopic deceleration strip which comprises a plurality of sections of deceleration strip bodies and further comprises a containing box arranged on the roadside and provided with a space capable of containing the deceleration strip body; a plurality of limiting holes buried in the road surface corresponding to the deceleration strip; limiting columns which areconnected with the deceleration strip body through telescopic assemblies and matched with the limiting holes in specification; and rollers arranged at the bottoms of the limiting columns; wherein theperipheries of the upper portions of the limiting holes are wrapped by a buffer body. The telescopic deceleration strip has the substantive effects that the deceleration strip body can be freely retracted and released, obvious concave-convex faces cannot be generated on the road surface after the deceleration strip body is retracted, the jolt of passing vehicles is reduced, the ideal effect of the telescopic deceleration strip is truly achieved, the structural stability is still high when the deceleration strip is started, the situations of sliding and the like cannot be generated, and the reliability can meet the toll road requirement.

Description

technical field [0001] The invention relates to the technical field of deceleration belts, in particular to a retractable deceleration belt for toll roads. Background technique [0002] Existing deceleration strips utilize the violent bumpy feeling produced when the vehicle passes quickly, which causes the driver's psychological discomfort and forces the vehicle to slow down and pass. However, in some cases, it is not necessary to arrange speed bumps all the time on specific road surfaces, so there are some retractable speed bumps on the market for easy storage when not needed, but the structural stability and strength of the moving parts are poor, for This prior art generally needs to lay tracks on the ground to prevent the speed bump from slipping during use. [0003] For example, the invention of authorized notification number CN108487105B discloses a retractable hidden road deceleration belt, including a mounting assembly and a deceleration assembly. The mounting assemb...

Problems solved by technology

[0004] Although the track used in the prior art facilitates the movement and limit of the deceleration belt, after the deceleration belt is put away, the uneven structure of the track will also cause certain bumps when the vehicle passes, so there is an urgent need for a vehicle that can ensure Structural strength when in use, without leaving obvious speed bumps on the track when stowed
