It sliding in the circular rails guide hole 29 of the second end wall 9, the second circular rails 16 slide in the circular rails guide hole 29 of the first end wall 5,
Circular cylinder piston 4 slides in circular cylinder；The support 7 of first axle sleeve and the second axle sleeve support 8 are separately mounted to circular cylinder
The inner edge surface both ends of inner wall 17, and the support 7 of the first axle sleeve and the second axle sleeve support 8 are fixed on 12 outside of swinging axle axle sleeve；Such as Fig. 3
Shown, swinging axle axle sleeve 12 is fixed on the first plectane 11, and damper 18 is mounted on the first plectane 11, and swinging axle 13 is successively worn
Overdamp device 18, the first plectane 11, swinging axle axle sleeve 12, the second plectane 22；Piston angle 6, ring are provided on circular cylinder piston 4
1 one end of shape cylinder outer wall is equipped with circular cylinder air inlet 19.
Above-mentioned circular cylinder air inlet 19 is connected through jettron 46 with air bag escape pipe 54 by gas-guide tube.
In the present invention, jettron 46 can be opened under certain pressure, when on Vehicular impact to safe road stake, column the
One riser 37 is deformed by very big impact force, be mounted on air bag 38 between the 4th riser 47 of column starting stave 37 and column by
To extruding, after the gas in capsule reaches certain pressure, jettron 46 is opened, and the high pressure gas in air bag 38 passes through air guide
Pipe enters from circular cylinder air inlet 19；Before safe road stake is hit, the piston angle 6 of circular cylinder piston 4 is located at ring
At shape cylinder intake hole 19, the purpose that piston angle 6 is provided on circular cylinder piston 4 is to prevent circular cylinder piston 4 will be annular
Cylinder intake hole 19 blocks；After being hit, piston angle 6 will receive the thrust of high pressure gas first, and subsequent circular cylinder is living
The first end wall 5 is left in one end of plug 4, and high pressure gas pushes circular cylinder piston 4 to slide to the second end wall 9, swinging axle 13, first
Circular rails support the 10, second circular rails support 14 to rotate counterclockwise, and retaining spring 20 is compressed, the card being fixed on swinging axle 13
The rotation of 42 reverse finger of hook, grab 42 can wear out the first plate of column 40, catch on front engine cover of car, and the gib head 52 of grab 42 can be embedded in vapour
In Chinese herbaceous peony cover.It can control the angle of the rotation of grab 42 by retaining spring 20, the angle for rotating grab 42 every time is fixed
It is constant.If speed is excessively high, impact force is excessive, may result in servo motor 41, grab 42, swinging axle 13 from safety post side plate
It is detached from and flies out on 39, grab 42 is connected in fixation with steel wire structure 48 by steel wire, and fixation with steel wire structure 48 is mounted on bottom
To guarantee that it will not be pulled by steel wire and be detached from ground in ground, once grab 42 flies out, steel wire can be held grab 42, into
And guarantee the automotive safety caught on by grab 42.
As shown in figure 5, above-mentioned damper 18 includes attenuator end cap 21, damping oil export 23, damping oil inlet 24, damping
Device shell 25, damping snap-gauge 26, damping slide plate 27, damping side plate 28, wherein damping snap-gauge 26 is fixed in shell 25
Side, damping slide plate 27 are fixed on swinging axle 13, and damping oil export 23 and damping oil inlet 24 are equipped on shell 25
And damping 27 two sides of slide plate are located at, damping oil export 23 is connect by damping oil pipe with damping oil inlet 24；Damp side plate
28 are mounted on the first plectane 11, and shell 25 is mounted on damping side plate 28, and it is outer that attenuator end cap 21 is mounted on damping
On shell.
In the present invention, when high pressure gas moment pouring circular cylinder, circular cylinder piston 4 is in air pressure and retaining spring 20
It can occur of reciprocating vibration under collective effect, damper 18 can prevent the of reciprocating vibration of circular cylinder piston 4, keep circular cylinder living
Plug 4, which reaches a position, to be stopped.When safe road stake is knocked, the damping snap-gauge 26 being mounted on shell 25 is motionless,
The damping slide plate 27 being mounted on swinging axle 13 is rotated with swinging axle 13；Damping oil is full of in damper 18, if from damper
End cap 21 sees that damping slide plate 27, which rotates clockwise, to squeeze out damping oil from damping oil export 23 to damping 28 direction of side plate,
Enter damping oil inlet 24 by damping oil pipe.Since damping oil pipe is very thin, damping oil can not be rapidly from damping oil export 23
It is discharged to damping oil inlet 24, the pressure of damping oil can prevent damping slide plate 27 from moving back and forth, to prevent circular cylinder piston 4
It is of reciprocating vibration.
The gib head 52 of above-mentioned grab 42 is upwards and between the first plate of column 40 and the second plate of column 44.Gib head 52 to
On, front engine cover of car can be caught on after grab 42 turns an angle.
Filled with high pressure gas in above-mentioned air bag 38.High pressure gas can push circular cylinder piston 4.In air bag 38 originally
When design with high pressure gas can enhance the opening of jettron 46, the enough height of gas pressure in air bag 38 are so that energy
42 moment of grab is enough allowed to block automobile cover.
Above-mentioned connection damping oil export 23 and the damping oil pipe for damping oil inlet 24, which can be, is able to bear damping oil pressure
Hose, be also possible to metal tube.
A kind of safe road stake with grab described above, it is characterised in that: the wall thickness of the damping oil pipe is 0.3-
3.0mm。
In conclusion air bag 38 is mounted between the 4th riser 47 of column starting stave 37 and column in the present invention, when vehicle is hit
When hitting on safety post, column starting stave 37 is extruded by collision deformation, air bag 38, and the high pressure gas in air bag 38 passes through ring
Shape cylinder intake hole 19 enters circular cylinder, and swinging axle 13 starts turning, and the grab 42 being mounted on swinging axle 13 will wear out column
First plate 40, catches on front engine cover of car；The configuration of the present invention is simple can play effective buffering when Vehicular impact road column
Effect mitigates damaged vehicle degree.With stronger practical function.
