In the range of the utility model protection.
Embodiment according to the present utility model provides a kind of energy-absorbing anti-collision safety barrier.
It as depicted in figs. 1 and 2, include: multiple guardrail lists according to the energy-absorbing anti-collision safety barrier of the utility model embodiment
Member 1, each fence unit 1 includes: support construction 21, and the endergonic structure 23 outside support construction 21 is arranged in, wherein is inhaled
Energy structure 23 is made of the responsive materials that non-newtonian fluid forms.
By means of the above-mentioned technical proposal of the utility model, it is made of by adding in fence unit non-newtonian fluid
Endergonic structure made of responsive materials, to absorb collision energy by using flexible energy-absorbing material, itself can restore after collision,
It is small to vehicle and personal damage, reduce traffic accident lethality.
In order to preferably describe the technical solution of the utility model, detailed retouch is carried out below by specific embodiment
It states.
As shown in Figure 1, the Collsion proof safety guardrail includes four fence units 1, wherein two fence units 1 are used as column,
Other two fence unit 1 is used as spreader, to each spreader and above-mentioned two column are connected to each other, although in addition, Fig. 1 shows
Gone out a kind of specific structure of Collsion proof safety guardrail, but ability just it will be appreciated by the skilled person that the tool of the Collsion proof safety guardrail
Body structure can be configured according to actual needs, for example, one embodiment according to the present utility model, the Collsion proof safety guardrail packet
Including four fence units 1 and a pedestal, wherein two fence units 1 are used as column, other two fence unit 1 is used as spreader,
