The shock absorbing unit 130 may be configured such that the first shield plate 110 and the second shield plate 120 are coupled to each other such that the jumping movement of the shock absorber 10 is allowed to be constant by a predetermined external force or more. .

The shock absorbing coupling portion 130 includes a post member 141, a bolt 145, and a nut 146.

The post member 141 is fixed to the ground so as to face the area where the first blocking plate 110 and the second blocking plate 120 are arranged so as to overlap with each other, and is provided so as to extend upward.

The post member 141 is formed with a fixing hole 141a through which the body portion 144 of the bolt 145 is inserted.

It is a matter of course that the post member 141 is formed in the shape of a quadrangular prism, and the post member 141 may be formed in a cylindrical shape different from the illustrated example.

The bolts 145 and the nuts 146 are applied as an engaging pin member that is coupled to the post member 141 through an area where the first blocking plate 110 and the second blocking plate 120 are overlapped with each other.

The bolt 145 has a head portion 143 formed to have a polygonal surface and a body portion 144 having an outer diameter smaller than that of the head portion 143 and extending from the head portion 143.

The body portion 144 of the bolt 145 includes a rectangular portion 144a extending from the head portion 143 and having a polygonal cross-sectional shape, and a rectangular portion 144a extending from the rectangular portion 144a, And has a screw-formed portion 144b.

Here, the screw-formed portion 144b is formed to have an outer diameter smaller than that of the angular portion 144a.

The angled portion 144a of the bolt 145 is formed in a star-shaped cross-section, and unlike the illustrated example, the cross-sectional shape of the angled portion 144a may be formed in various shapes such as a triangle, a square, and the like.

The nut 146 is screwed on a screw thread formed on the body portion 144 of the bolt 145 by forming a screw thread on the inner circumferential surface.

Namely, the nut 146 is screwed to the threaded portion 144b of the bolt 145. [

The first and second insertion holes 112 and 112 are formed in a region where the first blocking plate 110 and the second blocking plate 120 are overlapped with each other and the body portion 144 of the bolt 145 is inserted The elongated hole 148 extending in the vertical direction to communicate with the angled portion 144a is provided with an interference resistance against the horizontal movement of the angular portion 144a and is bent in a sawtooth shape And has a saw-toothed portion 148a.

The first and second insertion holes 112 and 114 may be formed to have an inner diameter of a size such that the prismatic portion 144a can penetrate without resistance and block the entry of the head portion 143. [

The width of the sawtooth wave-like portion 148a in the up-and-down direction is formed so that the first width and the second width narrower than the first width are repeated along the sawtooth waveform along the horizontal direction, And the second width may be formed to be equal to or larger than the outer diameter of the angular portion 144a.

According to this structure, when an external force is applied from the shock absorber 20 in the direction in which the second blocking plate 120 approaches the first blocking plate 110, the sawtooth waveform portion 148a The moving distance is different even if the bolt 145 is not moved or moved.

Therefore, when the vehicle collides with the shock absorber 20 and the jolting movement occurs in the direction in which the shock absorber 20 is brought close to the median separator 10, the second interrupter 120 The angular portion 144a of the bolt 145 moves in a cushioning manner while overcoming the resistance due to the interference of the sawtooth wave portion 148a of the elongated hole in multiple steps, Thereby supporting the jumping movement of the shock absorber 20 and also providing the buffering supplement function.

In the illustrated example, two first blocking plates 110 and a second blocking plate 120 are coupled to the median separator 10 and the shock absorbing device 20 via the buffering coupling 130, A first blocking plate 110 and a second blocking plate 120 are formed on one side of the median separator 10 and the shock absorbing device 20 so as to be spaced apart from the shock absorbing unit 130 ) May be applied only to the structure that is coupled through the first and second electrodes.

According to the road shock absorbing auxiliary device 100 described above, it is possible to suppress the entry and departure of the vehicle by blocking the spacing space between the shock absorbing device 20 and the median separator 10, Can be complementarily provided.
