The protective cover 13 and the base 11 are respectively fixed at the upper end and the lower end of the support column 12, the protective cover 13 is used for protecting the connecting piece 3 positioned in the support column 12, and the base 11 is used for being fixed with the ground. The protective cover 13 is connected with the support column 12 through a clamping ring, the protective cover 13 is provided with a limiting ring 131, and when the protective cover 13 is installed, a gap is formed between the protective cover 13 and the upper end of the support column 12, so that the protective cover 13 is convenient to disassemble.

Referring to fig. 4 and 5, the connecting member 3 includes a connecting body 4 and a mounting block 5 hinged to one end of the connecting body 4. Connecting body 4 is articulated through first bolt assembly 6 with installation piece 5, and installation piece 5 is located support column 12 outward, and installation piece 5 rotates along first bolt assembly 6. The connecting bodies 4 can be connected in a row when both ends thereof are hinged to the mounting blocks 5. The articulated connection mode has guaranteed bigger rotational degree of freedom, provides great rotation interval, is favorable to the deformation on a large scale of horizontal bar 2 to this increase buffering effect is favorable to buffering energy-absorbing.

Connecting body 4 and support column 12 fixed connection, installation piece 5 and horizontal bar 2 fixed connection. One end of the connecting body 4, which faces away from the first bolt assembly 6, is provided with a second bolt assembly 7, and the connecting body 4 is fixedly connected with the support column 12 through the first bolt assembly 6 and the second bolt assembly 7.

A mounting gasket 41 is arranged between the second bolt assembly 7 and the connecting body 4, and one side of the mounting gasket 41 is attached to the outer surface of the supporting column 12. When an impact occurs, the mounting pad 41 is not displaced, but is deformed. The mounting pad 41 is larger than the mounting hole 121. The mounting block 5 is provided with an arc-shaped surface 51 which is attached to the inner surface of the rail 2. The arcuate surfaces 51 provide a better attachment of the mounting block 5 to the rail 2.
