Abstract
The utility model discloses a road engineering signboard convenient to replace warning information, which comprises a signboard main body, a placing cavity is arranged in the signboard main body, an adjusting plate is arranged in the placing cavity, a roller is connected and installed on the adjusting plate, a moving groove is arranged in the signboard main body, and the moving groove is provided with a groove. An inserting strip is connected to one side of the signboard body, moving blocks are fixedly installed at the upper end and the lower end of the adjusting plate, a rotating shaft is installed in the middle of a roller in a penetrating mode, a control box is connected to the bottom end of the rotating shaft, a driven gear sleeves the bottom end of the rotating shaft, a driving gear is connected to the driven gear in an engaged mode, and a first linkage bevel gear is arranged above the control box. According to the utility model, through the arrangement of the placing cavity, the phenomenon that the warning information is not completely checked and cannot be clearly seen due to the fact that the warning information is damaged by external pollutants can be avoided, and the warning information is driven to enter or slide out of the placing cavity through the rotation of the roller, so that the warning information is more convenient to replace.
