Road warning board

Abstract

The invention discloses a road warning board, and relates to the field of roads. The road warning board comprises a warning board, the tops of the left side and the right side of the warning board aremovably connected through a movable shaft, movable adjusting connecting pieces are arranged in the middles of the left side and the right side of the warning board, the warning board is adjusted through the movable adjusting connecting pieces, and a base block is fixedly installed at the bottom of the warning board. An adjusting ball rotates in an adjusting limiting groove, so that an upper driving ball and a lower driving ball of the adjusting ball extrude the side wall of a small-specification groove hole in the upper portion of the interior of the adjusting limiting groove through a large-specification groove hole in the lower portion of the interior of the adjusting limiting groove, the upper and lower driving balls of the adjusting ball extrude the wall surface of the corresponding position of the inner side of the supporting block, so that the corresponding position of the pressed adjusting groove is extruded, the pressed adjusting groove presses a suction cup through the auxiliary pressed groove and the connecting column, the suction cup is adsorbed to the ground, and the warning board is prevented from being blown by strong wind to shift and the like.

Description

technical field [0001] The invention relates to the field of roads, in particular to a road warning sign. Background technique [0002] When construction or special treatment is carried out on roads or squares, warning signs are usually set up in the visible area outside the working area to remind and warn passers-by that the area cannot be approached. In actual use, due to part of the working environment, it is impossible to observe from the outside. , At the same time, workers cannot remind in time. At this time, the warning signs need to be placed in designated positions and cannot be moved. Although the current warning signs are basically relatively stable, when encountering strong winds and other conditions, the warning signs will move parallel on the ground. As a result, the warning sign is easy to shift from its original position, thereby reducing the warning effect. Therefore, we propose a road warning sign.
