Deceleration strip for preventing rear-end collision at road exit
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.
本发明公开了一种道路出口防追尾的减速带，包括机体，所述机体上端面上设有开口向上的操作腔、顶起腔，所述操作腔内设有减速机构，所述操作腔上端面上设有开口向上的两个滑动腔，所述滑动腔内设有制动机构，所述顶起腔内设有顶起机构，所述减速机构包括位于所述操作腔后内壁上设有开口向前的移动腔，所述移动腔内滑动连接有移动块，该发明结构简单，操作便捷，出口处有车辆停下时，通过机械传动可以完成自动打开警示牌对后方车辆提醒安全距离，当后方车辆向前行驶时，通过机械传动可以实现将后方车辆进行原地打滑而防止造成追尾事件，当前方车辆离开后，通过机械传动可以实现将后方车辆脱离打滑而保持交通顺畅，从而减轻工作者的工作量。
