End is provided with fixed seat 2.Column 1 is arranged on by fixed seat 2 and uses ground.
The upper end of the column 1 is provided with relative baffle plate 3, in the present embodiment, two relative gears is set on each column 1
Plate 3, forms groove between the column 1 and baffle plate 3, crossbeam 4 is erected between the groove of two neighboring column 1；The crossbeam 4
First buffer layer 5 is provided between the baffle plate 3, the crossbeam 4, first buffer layer 5 and baffle plate 3 pass through the and of the first bolt 6
First nut 7 tightens together.In the present embodiment, mounting hole 8 is provided with the first buffer layer 5, first bolt 6 is passed through
The mounting hole 8, is arranged with spring 9, the two ends difference of the spring 9 on first bolt 6 in the mounting hole 8
Connect with the column 1 and crossbeam 4.Double buffering is realized by first buffer layer 5 and spring 9 between column 1 and crossbeam 4.Institute
State and first is provided with column 1 screws togather groove 10, the termination of first bolt 6 and the first nut 7 screw togather groove positioned at described first
In 10；So ensure the surface smooth and beautiful appearance of column 1, without projection, it is to avoid scratch.
The crossbeam 4 is combined into by left beam 11 and right beam 12 are relative, and the left beam 11 and right beam 12 are by the second bolt 13
Tightened together with the second nut 14；Lower end at the left beam 11 and the abutted surface of right beam 12 offers some ball recess 15,
Some ball recess 15 set gradually along the length direction of the crossbeam 4；In the present embodiment, on the inside of left beam 11 and right beam 12
Half ball recess 15 is each provided with, complete ball recess 15 is formed when left beam 11 and relative right beam 12, crossbeam 4 is set
It is left beam 11 and right beam 12, convenient processing ball recess 15 is also convenient for actual installation and maintenance.
The lower end of the ball recess 15 sets and be equipped with opening, the ball recess 15 rotation ball 16, the rotation ball
16 are connected with railing 17, and the railing 17 is stretched out by the lower ending opening of the ball recess 15；It is described to rotate ball 16 and the ball
Second buffer layer 18 is provided between connected in star 15.When 17 stress of railing, can be turned an angle with ball 16 is rotated, realized
Buffering, to rotate and realize buffering by second buffer layer 18 between ball 16 and ball recess 15.
Second is provided with the left beam 11 and right beam 12 and screws togather groove 19, the termination of second bolt 13 and the second nut
14 screw togather in groove 19 positioned at described second, and the outside of the crossbeam 4 is enclosed with three buffer layer 20.By the termination of the second bolt 13
Screwed togather in groove 19 located at described second with the second nut 14, it is ensured that the surface of crossbeam 4 is smooth without projection, facilitates three buffer layer 20
Set, also avoid three buffer layer 20 from there is hard protrusion, it is to avoid the injury to accident vehicle.Here three buffer layer 20 can be with
Cushion collar is set to, is directly set on crossbeam 4, easy disassembly.
The railing 17 is provided with upper limit position block 25 and lower position block 26, and upper limit position block 25 and lower position block 26 here are
Disc, being provided with the railing 17 between the upper limit position block 25 and lower position block 26 can be with the railing 17 for axle center is entered
The roller bearing 27 that row is rotated.In the present embodiment, the roller bearing 27 includes the rolling support frame 28 being set on the railing 17, described
The periphery of rolling support frame 28 is provided with reflector layer 29, and in the present embodiment, reflector layer 29 is resin bed, the resin bed inner homogeneous
It is inlaid with glass microballoon 31；Elastic foamed body 30, the bullet are filled between the rolling support frame 28 and the reflector layer 29
Property foams 30 be made up of the high elastic rubber composition using electronic crosslinking foaming PE materials or EVA materials.When roller bearing 27 is subject to
During shock, a part of Impact energy is absorbed using own material, while moved with vehicle and rolled so that motor vehicle slowly entangles
Partially.Vehicle can be irradiated reflector layer 29 the light reflection for coming, beneficial to vehicle it was observed that the position of guardrail, reduces accident and occur.
The lower end of the railing 17 is provided with suspension ring 21, and suspension ring 21 here are annulus, are fixed on the bottom of railing 17.Phase
Be connected with chain 22 between adjacent two bottoms of column 1, the length of the chain 22 more than between two neighboring column 1 away from
From so when railing 17 is clashed into, chain 22 gives the enough spaces of railing 17 and produces displacement；The chain 22 is worn successively
Cross each suspension ring 21, when the railing 17 in somewhere is clashed into, chain 22 with the outwardly tension of railing 17, while limiting thing
Therefore the displacement of vehicle.
In the present embodiment, the bottom of the suspension ring 21 is provided with clamping projection 23 protruding upward, and the card of the chain 22 sets
In the clamping projection 23.So when chain 22 is installed, the length of the chain 22 between adjacent suspension ring 21 can be kept
It is isometric, chain 22 is fixed with suspension ring 21 by clamping projection 23, it is ensured that attractive in appearance.Here, the clamping raised 23 is columnar member,
The chain 22 is formed by connecting by some beckets 24, and the columnar member blocks the chain 22 through a becket 24
Firmly.The rigidity of clamping projection 23 is relatively low, and chain 22 is fixed under normal circumstances to have no problem, but when railing 17 is subject to very favourable opposition
When hitting power, chain 22 can be slided in suspension ring 21, and clamping projection 23 can fracture, therefore clamping projection 23 does not interfere with chain 22
Movement, the movement of railing 17 will not be hindered.
The present embodiment, can be by first buffer layer 5, spring 9, second buffer layer 18, when using, when there is Vehicular impact
Three buffer layer 20, the rotation of railing 17, the rolling of roller bearing 27 and the tension of chain 22 are realized buffering, are rectified a deviation and spacing, reduce
Impact injury to accident vehicle and personnel.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
