Problems solved by technology
[0002] During road construction, although there is a blue warning sign, due to the driving angle, it is easy to confuse the color of the warning sign with the road, and the size of the warning row is uniform, and drivers do not know the construction behind the warning sign The specific size of the site is that people will place multiple warning signs on the roads to block the construction site, but this will increase the physical labor of the construction workers. It is necessary to have a warning sign device that is easy to move and can increase the warning effect. Now Some road construction warning devices do not have the function of automatically increasing the warning effect and warning area. A road construction warning device set forth in the present invention can solve the above problems

Embodiment Construction
[0016] Combine below Figure 1-5 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0017] A warning device for road construction according to the present invention includes a box body 11, a cavity 12 is arranged inside the box body 11, an electric push rod 21 is fixed on the inner wall of the upper side of the cavity 12, and the electric push rod The lower side of 21 is fixed with a sliding rod 13 that is slidably connected to the side wall of the cavity 12, and the lower side of the sliding rod 13 is fixed with two connecting rods 16 that are symmetrical about the left and right of the electric push rod 21 and extend downward. The outside of the connecting rod 16 is provided with a connecting box 44 that is slidably connected to the lower inner wall of the cavity 1...

The invention discloses a warning device for road construction. The warning device comprises a box body, a cavity is formed in the box body, an electric push rod is fixed to the inner wall of the upper side of the cavity, and a sliding rod connected to the side wall of the cavity in a sliding manner is fixed to the lower side of the electric push rod; and two connecting rods which are bilaterallysymmetrical about the electric push rod and extend downwards are fixed to the lower side of the sliding rod. By means of the warning device, the warning effect of the warning device during road construction can be improved, the transverse area of a warning panel can be enlarged, meanwhile, the warning panel can integrally move upwards, the construction position can be completely covered, the possibility of danger caused by the fact that a warning sign cannot completely cover the construction position can be reduced, the brightness of a warning red light can be changed according to the distanceof driving, and drivers can be effectively warned.
Description
technical field [0001] The invention relates to the field of road construction, in particular to a warning device for road construction. Background technique [0002] During road construction, although there is a blue warning sign, due to the driving angle, it is easy to confuse the color of the warning sign with the road, and the size of the warning row is uniform, and drivers do not know the construction behind the warning sign How big is the site? People will place multiple warning signs on the road to block the construction site, but this will increase the physical labor of the construction workers. It is necessary to have a warning sign device that is easy to move and can increase the warning effect. Now Some road construction warning devices do not have the function of automatically increasing the warning effect and warning area. The road construction warning device described in the present invention can solve the above problems. Contents of the invention [0003] T...
