The night road maintenance warning board 13 shown in fig. 1-3 comprises a base 1, wherein a support column 2 is arranged on the surface of the base 1, a movable protective cover 3 is sleeved outside the support column 2, a plurality of buffer parts are connected between the inner wall of the protective cover 3 and the outer wall of the support column 2, a driving part is arranged at the top end of the support column 2, a connecting rod piece extending vertically upwards is arranged at the top end of the driving part, and a warning component is arranged at the top end of the connecting rod piece;

a plurality of fixing bolts 4 penetrate through the edge of the base 1;

on the basis of the above, during the use, place base 1 subaerial, fix base 1 through fixing bolt 4, support column 2 is fixed on base 1, protects support column 2 at protection casing 3 in the support column 2 outside, and when whole part received the collision, protection casing 3 removed and extruded the bolster, absorbed the energy when the collision, reduced the damage that the collision caused support column 2 and its top part.

The angle is adjusted through the universal joint, so that no matter the angle is used for collision and impact, a good buffering and energy absorbing effect can be obtained.

A layer of buffer rubber cushion 5 is fixedly attached to the outer wall of the protective cover 3;

the cushion rubber 5 initially cushions the impact when the protective cover 3 is impacted.

The buffer piece comprises a first universal joint 6 fixed on the outer wall of the support column 2 and a second universal joint 7 fixed on the inner wall of the protective cover 3, and a spring telescopic rod 8 is connected between the first universal joint 6 and the second universal joint 7;
