Lower movement, allows airbag aeration, plays cushioning effect, the larger kinetic energy for absorbing vehicle protects vehicle.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：Bearing 1, strut 2, slide bar 3, connecting plate 4, rubber slab 5, air bag 6, pipeline 7, inserted link 8, sleeve 9, piston
10, the first spring 11, second spring 12, support plate 13, third spring 14.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：
Road guard with shock-absorbing function, including bearing 1, the upper surface of bearing 1 symmetrically open up that there are two the first bar shapeds
Sliding slot slidably connects slide bar 3 in the first bar shaped sliding slot, and two slide bars 3 are symmetrical arranged about strut 2, and two slide bars 3 are opposite
Side wall is connected to the both sides of strut 2 by third spring 14 respectively, and the lower end of strut 2 is fixedly connected with the upper surface of bearing 1, branch
The upper end of bar 2 is fixedly connected on the lower face of support plate 13, and the upper surface of support plate 13 offers the second bar shaped sliding slot, and the second bar shaped is slided
It is slidably connected in slot there are two sleeve 9, is connected by second spring 12 between two sleeves 9, the inner bottom wall of sleeve 9 passes through first
Spring 11 connects the side of piston 10, and the other side of piston 10 is fixedly connected with one end of inserted link 8, and the other end activity of inserted link 8 is passed through
It wears cylinder 9 to reach the outside of sleeve 9 and be fixedly connected with the side of connecting plate 4, the other side of connecting plate 4 is fixedly connected with rubber slab
