After the first bracket 3 and the second bracket 4 are vertically erected, the cross frame 1 is suspended on the ground, and an isolation net 7 is fixedly installed between the two groups of nets 6. A through slot 8 is opened on the cross frame 1 at a position corresponding to the isolation net 7. In the storage and transportation state, the first bracket 3 and the second bracket 4 are respectively stacked above the cross frame 1. At this time, the isolation net 7 can be wrapped around the cross frame 1 after passing through the through slot 8. When unfolding and installing, the isolation net 7 is untied, and the first bracket 3 and the second bracket 4 are propped up and fixed on the road surface, so that they can be quickly unfolded and stored, and the structure is simple and easy to produce.

[0027] Furthermore, the width of the first bracket 3 and the second bracket 4 are both half of the width of the horizontal frame 1. The first bracket 3 and the second bracket 4 are arranged on the horizontal frame 1 front and back without interfering with each other, and are convenient to store after folding.

[0028] Furthermore, the isolation net 7 is coated with reflective paint to serve as a warning in the dark.

[0029] Furthermore, the distance between the bottom of the isolation net 7 and the hinge 2 is greater than the distance between the through slot 8 and the hinge 2, so that the isolation net 7 can pass through the through slot 8 more conveniently after being stored.

[0030] In other embodiments, a grounding plate 9 is welded to the legs 5 of the first bracket 3 and the second bracket 4 . A hole is provided on the grounding plate 9 , and a nail is passed through the grounding plate 9 to fix it on the road surface.

Due to this arrangement, when the two groups of isolation devices are connected end to end, they can be connected not only in a straight line but also at right angles, which is more flexible.

[0032] In other embodiments, a connecting plate 10 is further included. Two groups of nail holes 12 are opened on the connecting plate 10. The nail holes 12 correspond to the holes on the grounding plate 9. When the two groups of isolation devices are connected end to end, the connecting plate 10 is covered on the two groups of connecting plates 10, and the two groups of grounding plates 9 are connected obliquely. Furthermore, the two ends of the connecting plate 10 are flush with the edge of the grounding plate 9 to form an oblique groove 13 for easy storage.

[0033] Furthermore, a slot 11 is formed at the bottom of the first bracket 3 and the second bracket 4 , and the connecting plate 10 can slide in the slot 11 to limit the position of the connecting plate 10 .

[0034] The working principle of the utility model is as follows: in the storage and transportation state, the first bracket 3 and the second bracket 4 are respectively stacked on the cross frame 1. At this time, the isolation net 7 can be wrapped around the cross frame 1 after passing through the groove 8. When unfolding and installing, the isolation net 7 is untied, and the first bracket 3 and the second bracket 4 are propped up and fixed on the road surface, so that they can be quickly unfolded and stored, and the structure is simple and easy to produce.
