Traffic deceleration strip device for extending deceleration

Abstract

The invention discloses a traffic deceleration strip device capable of extending and decelerating. The device comprises a road, a first sliding groove with an upward opening is formed in the top wallof the road. First sliding blocks are slidably connected into the first sliding groove in a bilateral symmetry mode. A cambered surface block is arranged between the left and right first sliding blocks; the end wall, away from the cambered surface block, of the first sliding block is connected with the first sliding groove through a first spring; the top wall of the first sliding block is fixedlyprovided with a slope block slidably connected with the top wall of the road; a second sliding block is fixedly arranged on the bottom wall of the cambered surface block; second sliding grooves with openings back to the second sliding block are symmetrically formed in the left and right end walls of the cambered surface block; the second sliding groove is in sliding connection with the first sliding block. Third sliding grooves are formed in the bottom walls of the left-right first sliding grooves. Two fourth sliding grooves with upward openings are symmetrically formed in the bottom wall of the sliding shaft in the front-back direction, bumping buffer mechanisms are arranged in the fourth sliding grooves, buffer extending speed reducing mechanisms are symmetrically arranged on the left end walls and the right end walls of the fourth sliding grooves, the speed reducing section of the speed bump can be prolonged, the speed reducing effect of the traffic speed bump is enhanced, and subsequent vehicle slipping can be avoided.

Description

Technical field [0001] The invention relates to the related technical field of traffic speed bumps, in particular to a traffic speed bump device for extended speed reduction. Background technique [0002] Traffic speed bumps are also called deceleration ridges, which are traffic facilities installed on highways to slow passing vehicles. Generally, it is alternated with yellow and black to attract visual attention, and the road is slightly arched to achieve the purpose of vehicle deceleration. It is generally set at road crossings, industrial and mining enterprises, schools, residential communities and other road sections where vehicles need to slow down and road sections that are prone to traffic accidents. It is a new type of traffic-specific safety setting used to reduce the speed of motorized and non-motorized vehicles. [0003] At this stage, the deceleration effect of traffic deceleration belts is not significant enough, and the resulting turbulence is too large. The decelera...

AI Technical Summary

Problems solved by technology

[0003] The deceleration effect of the traffic deceleration belt at the current stage is not significant enough, causing too much bumpy feeling. The deceleration effect of entering the deceleration zone is the same as leaving the deceleration zone, which is not conducive to traffic driving, and the sand brought by vehicles passing by will cause subsequent vehicles to skid Danger
