Warning board for road construction

Abstract

The invention relates to the technical field of road construction, and in particular relates to a warning board for road construction. The warning board for road construction comprises a base, whereinslide bars are symmetrically arranged at the upper end of the base; sliding plates are connected on the outer sides of the slide bars in a sleeving manner; the warning board is arranged at the upperends of the sliding plates; shaft sleeves are arranged at the lower ends of the sliding plates; a first screw is arranged in each shaft sleeve; a first swivel nut is connected to the upper end of thebase in a locking manner; the end, far from the shaft sleeve, of the first screw penetrates through the first swivel nut and is connected to a second gear; supporting legs are symmetrically arranged at the lower end of the base; a first gear engaged to the second gear is arranged in the base; and the lower end of the first gear penetrates through the base and is connected to a first rotary disc through a second connecting rod. Compared with the prior art, the device moves and is fixed after moving, and the height of the warning board is adjusted, so that the warning board is simple in structure, is used for road construction conveniently, and is worth being popularized.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a warning sign for road construction. Background technique [0002] In order to strengthen on-site construction safety, driving and personal safety, road warning signs have become an indispensable warning tool, which has played a role in prompting and guiding people. However, in the process of small-scale road construction repairs, construction workers will carry tools to the construction site , and repair the repaired position and continue to the next construction repair position, resulting in the need to move the tools multiple times during the construction process, but although the general road construction warning signs can be moved, they do not take into account the movement and Fixed after moving, and the warning sign cannot be adjusted according to the specific construction situation, so we propose a warning sign for road construction.
