AI Technical Summary
Existing road guardrails can only provide collision protection and buffering on one side, and cannot provide collision protection and buffering on both sides. At the same time, when vehicles behind are congested after a collision on one side, rescue vehicles cannot quickly enter the accident scene, and vehicles cannot quickly leave the other side.
A multi-directional anti-collision buffer road barrier is designed. A sliding rod is set between the first fixed frame and the second fixed frame, and an anti-collision buffer assembly is installed between the sliding rods, including a fixed rod, a buffer rod, an anti-collision plate and a spring. The sliding of the sliding rod drives the anti-collision buffer assembly to move laterally and adjust, forming an evacuation channel and realizing multi-directional anti-collision buffer.
It provides collision protection and buffering on both sides of the road, enabling the rapid formation of evacuation lanes in the event of an accident, facilitating vehicle evacuation and rescue vehicle access to the accident scene, and improving the efficiency of accident handling.

Abstract
Claims
1. A multi-directional anti-collision buffer type road isolation fence comprising a first fixed frame (1) and a second fixed frame (2) of an I-shaped structure, characterized in that, The first fixing frame (1) and the second fixing frame (2) are provided with sliding grooves (3) at their four corners. The two sliding grooves (3) on the same side of the first fixing frame (1) are slidably connected to the sliding rods (4). The end of the sliding rod (4) away from the first fixing frame (1) extends into the corresponding sliding groove (3) on the second fixing frame (2) and is slidably connected to it. Anti-collision buffer components are provided at equal intervals between the two sliding rods (4).
2. The multi-directional crashworthy cushioned highway barrier of claim 1, wherein: The anti-collision buffer assembly includes a fixed rod (5), a buffer rod (6), an anti-collision plate (7), and a spring (8). The fixed rod (5) is fixedly connected at equal intervals between two sliding rods (4). The buffer rod (6) is slidably connected at equal intervals to the outside of the fixed rod (5). The anti-collision plate (7) is fixedly connected to one end of the buffer rod (6). The spring (8) is sleeved on the outside of the buffer rod (6) and located between the anti-collision plate (7) and the fixed rod (5).
