Foldable warning board

Abstract

The invention provides a foldable warning board, which comprises a vehicle body, a lower warning board and an upper warning board, wherein the vehicle body is connected to a transport cart; the vehicle body is movably connected to the lower end of the lower warning board; the upper end of the lower warning board is movably connected to the lower end of the upper warning board; the upper warning board and the lower warning board are both provided with warning boards. The warning board can be horizontally placed to be convenient for transportation in a non-working state, and the folding is convenient; the warning board is large in area and enough in height in folding and unfolding working states, the warning function can be better played, and the practical effect of the warning board is improved; and the occurrence of various accidents can be effectively prevented, the safety of construction operation is protected, and the occurrence of safety accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of warning equipment, in particular to a foldable warning sign which can be moved by a trailer. Background technique [0002] In the process of repairing communication equipment, corresponding staff should set up warning signs. In order to ensure the safety of oneself and the road, especially in the context of the rapid development of expressways in our country, problems such as highway road garbage, street lamp pollution and insufficient brightness have become major hidden dangers of highway safety. Therefore, during the maintenance and cleaning of highways and tunnels, it is even more important To protect the workers themselves and construction safety, it is necessary to have corresponding warning equipment. For the existing warning signs, there are two types of integrated warning signs and foldable warning signs, and the integrated warning signs take up a lot of space and are difficult to transport, so us...

Problems solved by technology

In order to ensure the safety of itself and the road, especially in the context of the rapid development of expressways in our country, the problems of highway road garbage, street lamp pollution and insufficient brightness have become major hidden dangers of highway safety. Therefore, during the maintenance and cleaning of highways and tunnels, it is even more important To protect the workers themselves and construction safety, it is necessary to have corresponding warning equipment. For the existing warning signs, there are two types of integrated warning signs and foldable warning signs, and the integrated warning signs take up a lot of space and are difficult to transport, so use The frequency is low, but its warning effect is remarkable. The folding warning sign is easy to transport, but it needs to be installed and spliced ​​on site when it is used, and the splicing process is too cumbersome
