Be hingedly connected the lower side in the upper end of sliding block and baffle, be fixed with spring between the upper end and column of sliding block, sliding block and
Baffle is respectively positioned on the inside of shell, and the top of shell is provided with the straight slot that baffle can be allowed to pass through.
It is integrated on column to be fixed with the protrusion that section is dove-tail form as a kind of preferred embodiment of the utility model
Structure and the exposed top to shell of the upper end of the column, the side of baffle are provided with the sliding slot of dove-tail form, and baffle by sliding slot with
Bulge-structure is correspondingly connected with to be slidably connected on column.
As a kind of preferred embodiment of the utility model, 80cm, column phase are smaller than between two neighboring column
It carries on the back and is fixed with floor in the side of baffle, and the bottom of floor is fixedly connected with road and bridge matrix.
As a kind of preferred embodiment of the utility model, shell uses corrugated board structures.
As a kind of preferred embodiment of the utility model, sliding block height is not less than 50cm, and the tip height of sliding block
Less than the lower side of baffle, connected also by dovetail type groove between sliding block and sliding rail.
Compared with prior art, the advantageous effect that the utility model is reached is：When automobile is when hitting road and bridge guardrail, hit
The energy for hitting generation pushes sliding block close to column along sliding rail, applies thrust to connecting rod with the movement of sliding block, connecting rod pushes gear
Plate is moved up along column, improves the height of guardrail, the case where vehicle ploughs under road and bridge both sides or opposite track is substantially reduced, to drop
The seriousness of low collision accident preferably protects the safety of occupant.

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment
As shown in Figs. 1-2, a kind of road and bridge guardrail, including be embedded in the column 1 of road and bridge both sides and be enclosed in 1 periphery of column
Shell 5, column 1 are provided with multigroup and are vertically fixed on road and bridge along road and bridge trend at equal intervals, and the bottom of column 1 is vertically and fixedly provided with
Sliding rail 8 slidably connects baffle 3 on column 1, sliding block 7, the company of being provided between sliding block 7 and baffle 3 is slidably connected on sliding rail 8
Bar 4, the both ends of connecting rod are hingedly connected the lower side in the upper end of sliding block 7 and baffle 3, between the upper end of sliding block 7 and column 1
It is fixed with spring 6, sliding block 7 and baffle 3 are respectively positioned on the inside of shell 5, and the top of shell 5 is provided with baffle 3 can be allowed to pass through
Straight slot.
When automobile is when hitting road and bridge guardrail, the energy for hitting generation makes 5 Inward deflection of shell and pushes sliding block 7 along cunning
Rail 8 is close to column 1, applies thrust to connecting rod 4 with the movement of sliding block 7, while being carried out to spring 6 in 7 moving process of sliding block
Compression, accumulation of energy after spring 6 compresses absorb a part of Impact energy, push baffle 3 to be moved up along column 1 after 4 stress of connecting rod, baffle 3
The height of guardrail is improved after moving up, vehicle substantially reduces vehicle and plough under road and bridge two from that can stop to car body when overturning
The case where side or opposite track, to reduce the seriousness of collision accident, preferably protect the safety of occupant.
In the present embodiment, on column 1 integration be fixed with section be dove-tail form bulge-structure 10 and 1 upper end of column it is exposed
To the top of shell 5, the side of baffle 3 is provided with the sliding slot 9 of dove-tail form, and baffle 3 is corresponding with bulge-structure 10 by sliding slot 9
Connection is to be slidably connected on column 1.
The sliding slot 9 and bulge-structure 10 of dove-tail form, while playing the role of guiding role also have it is anti-detachment, avoid
3 unbalance stress of baffle is detached from from column 1.
In the present embodiment, 80cm is smaller than between two neighboring column, column is fixed with rib in the side of baffle opposite to each other
Plate, and the bottom of floor is fixedly connected with road and bridge matrix.
The width of current most of vehicles is more than 160cm, sets and is smaller than 80cm between two neighboring column 1, in this way
It can ensure that at least two columns 1 play barrier effect to car body when hitting, and improve the intensity of guardrail.
In the present embodiment, shell 5 uses corrugated board structures.Corrugated board structures have energy-absorbing function, further reduce and hit
The destruction of generation.
In the present embodiment, 7 height of sliding block is not less than 50cm, and the tip height of sliding block 7 is less than the lower side of baffle 3, sliding
It is connected also by dovetail type groove between block 7 and sliding rail 8.
Current most of chassis of vehicle body height are not higher than 50cm, and sliding block 7 is highly set and is not less than 50cm, it can be ensured that vapour
The rum point of vehicle is located on sliding block 7, and such guardrail just has better protective action, and the tip height of sliding block 7 is less than baffle 3
Lower side can thus make connecting rod 4 there is upward component baffle 3 to be pushed to move up the thrust of baffle 3, sliding block 7 and sliding rail 8
Between dovetail type groove connection structure, have the characteristics that stablize high.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
