Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1 and Figure 2, the emergent air cushion of negative pressure road surface safety of the present embodiment, comprise rubber pad 1 and inner balloon 2, during use, inner balloon 2 is placed in the accommodation space of rubber pad 1, described rubber pad is for the protection of inner balloon, and the both sides of described inner balloon 2 are respectively equipped with two gas ports, and a gas port is provided with air exhaust nozzle 3, a gas port is provided with exhaust nozzle 4, and described air exhaust nozzle and exhaust nozzle are equipped with Valve mouth cover 5; Described air exhaust nozzle is connected with the negative pressure aerating device for inflating to inner balloon, and described negative pressure aerating device is arranged in rubber pad.
