Detailed Description
In the following description of the present utility model, it should be understood that, for convenience of description and simplification of the description, the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. refer to the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are not to be construed as limiting the present utility model, but rather to indicate or imply that the devices or elements referred to must have specific directions, be configured and operated in specific directions.
Referring to fig. 1 to 3, the present embodiment provides a highway protective fence, which comprises an upright 1 and a rail 2, wherein a reed 5 is arranged between the upright 1 and the rail 2, the cross section of the reed 5 is omega-shaped, a fastening bolt 4 is connected between the rail 2, the reed 5 and the upright 1, a spring 6 is arranged between the reed 5 and the upright 1, and the spring 6 is movably sleeved on the surface of the fastening bolt 4.
Further, two sides of the omega-shaped reed 5 are in contact with the upright posts 1, a cavity is formed between the middle position and the upright posts 1, the spring 6 is positioned in the cavity, the reed 5 is made of metal, and when the cavity of the omega-shaped reed 5 is gradually reduced due to the impact force of a vehicle, which is received by the rail 2, the reed 5 can squeeze the spring 6, so that the reed 5 and the spring 6 can weaken the impact force received by the upright posts 1 to the greatest extent.
Further, a plurality of mounting holes 11 have been seted up on stand 1 surface, rail 2 passes through fastening bolt 4 to be installed in mounting hole 11, and fastening bolt 4 is clearance fit, not interference fit, can ensure that rail 2 receives the striking time, can drive fastening bolt 4 and remove in mounting hole 11, avoids impact force direct action at stand 1 surface, provides the room of buffering and energy-absorbing for reed 5 and spring 6.
