Deceleration strip for preventing rear-end collision at road exit

Abstract

The invention discloses a deceleration strip for preventing rear-end collision at a road exit. The deceleration strip comprises a machine body, an operation cavity with an upward opening and a jackingcavity are formed in the upper end face of the machine body, a deceleration mechanism is arranged in the operation cavity, two sliding cavities with upward openings are formed in the upper end face of the operation cavity, and braking mechanisms are arranged in the sliding cavities; and a jacking mechanism is arranged in the jacking cavity, the speed reducing mechanism comprises a moving cavity which is located on the rear inner wall of the operation cavity and provided with a forward opening, and a moving block is slidably connected into the moving cavity.The deceleration strip is simple instructure and convenient and fast to operate, when a vehicle stops at the exit, the warning board can be automatically opened through mechanical transmission to remind a rear vehicle of the safe distance, when the rear vehicle runs forwards, the rear vehicle can be slipped in situ through mechanical transmission to prevent rear-end collision accidents, and after the front vehicle leaves, through mechanical transmission, vehicles behind can be separated from slipping to keep smooth traffic, so that the workload of workers is reduced.

Description

technical field [0001] The invention relates to the field of traffic deceleration belts, in particular to a deceleration belt for preventing rear-end collisions at road exits. Background technique [0002] At the exit of various vehicles, the vehicle needs to operate and leave at the exit. At this time, it is necessary to wait for the vehicle to leave behind. At the exit, there are often rear-end vehicles that fail to maintain a safe distance and cause rear-end collisions, which not only cause harm to vehicles and people. damage and cause traffic jams. [0003] At present, the process of preventing vehicle rear-end collisions and rear-end collisions is performed manually. Not only does the process of preventing vehicle rear-end collisions and rear-end collisions occur cumbersomely, but it also consumes a lot of physical strength and increases the workload of workers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provi...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a deceleration belt for preventing rear-end collisions at road exits, which overcomes the problems of being unable to automatically prevent vehicle rear-end collisions and cannot automatically handle rear-end collisions, and increases the functions of automatically preventing vehicle rear-end collisions and automatically processing rear-end collisions
