[0024] The embodiment of the utility model provides a warning sign for highway construction with an anti-dumping function.

[0025] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A highway construction warning sign with an anti-dumping function includes a base 1 and a warning sign 2. A warning mark 21 is pasted on one side of the warning sign 2. A battery is embedded inside the warning sign 2. Both ends of the base 1 are open. By placing counterweights such as sandbags or bricks inside the two ends of the base 1, the overall stability of the device is increased. The warning mark 21 is glued to the warning sign 2 by glue.

[0026] Please refer again Figure 1 and Figure 2 The base 1 is provided with a warning sign 21 on one side of which is fixedly connected an LED light strip 23, which is electrically connected to a battery. The warning sign 2 is provided with a control switch 8 for controlling the opening and closing of the LED light strip 23. The LED light strip 23 is used at night to improve the warning effect at night. The LED light strip 23 is powered by a battery, and the control switch 8 is used to control the LED light strip 23 to light up and close.

[0027] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 There are through grooves on both sides of the base 1. Two sliding rods 3 are slidably connected to the inside of the base 1. The two ends of the sliding rods 3 extend to the outside of the base 1 through the through grooves. The inner top wall of the base 1 is fixedly connected to a fixed sliding rod 31. The sliding rod 3 is slidably connected to the fixed sliding rod 31. Under the action of the fixed sliding rod 31, the sliding rod 3 slides stably inside the base 1.

[0028] Both ends of each sliding rod 3 are hinged with an extrusion rod 4 through a pin, and the other end of the extrusion rod 4 is hinged to a connecting block 5 through a pin. When the two sliding rods 3 slide close to each other, the connecting block 5 is squeezed by the extrusion rod 4 to push the connecting block 5 up. Conversely, when the two sliding rods 3 move away from each other, the connecting block 5 is controlled to descend under the connecting action of the extrusion rod 4.

[0029] The warning sign 2 is connected between the two connecting blocks 5 by rotating through a rotating shaft. When the warning sign 2 is blown by the wind, it is driven to flip over to prevent the warning sign 2 from moving and falling under the influence of the wind. The top of the base 1 is inlaid with a magnet 12, and the bottom of the warning sign 2 is inlaid with an iron sheet. Under the action of the magnet 12 and the iron sheet, the warning sign 2 always remains vertically upward when no force is applied.

[0030] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The sliding rod 3 is provided with a limiting mechanism that limits the sliding of the sliding rod 3. The limiting mechanism includes a movable plug-in block 6. A groove is provided on the top of the sliding rod 3. The movable plug-in block 6 slides inside the groove. A slot 11 is provided on the top of the base 1 that matches the position of the movable plug-in block 6. One end of the movable plug-in block 6 is inserted into the inside of the slot 11. When one end of the movable plug-in block 6 is inserted into the inside of the slot 11, the sliding rod 3 is restricted from sliding inside the base 1. By manually pressing one end of the movable plug-in block 6, it is pushed into the inside of the groove from the inside of the slot 11. The bottom of the movable plug-in block 6 is fixedly connected to a spring 61, and the other end of the spring 61 is fixedly connected to the inner bottom wall of the groove. Under the action of the elastic force of the spring 61, the movable plug-in block 6 quickly slides and resets when it is not under force.

[0031] Please refer again Figure 1 and Figure 2A pair of solar photovoltaic panels 71 are installed on the other side of the warning sign 2. The solar photovoltaic panels 71 are electrically connected to the battery. The solar photovoltaic panels 71 collect solar energy and convert it into electrical energy for storage in the battery. A placement slot 22 is provided on one side of the warning sign 2. The interior of the placement slot 22 is hinged with a movable plate 7 through a pin shaft. The solar photovoltaic panel 71 is embedded in the movable plate 7. The other side of the movable plate 7 is hinged with a tightening rod 72 through a pin shaft. The other end of the tightening rod 72 is pressed against the placement slot 22. Under the action of the tightening rod 72, the solar photovoltaic panel 71 is adjusted to an inclined shape to facilitate the absorption of sunlight, and the movable plate 7 is stored through the provided placement slot 22.

[0032] When the movable block 6 slides to the next slot 11, the spring 61 quickly drives the movable block 6 to slide up and insert into the slot 11 to limit the sliding of the sliding rod 3, and rotates the warning sign 2 from the horizontal to the vertical, and keeps the warning sign 2 vertical under the action of the magnet 12 and the iron sheet. When the warning sign 2 is blown by the wind, the warning sign 2 can rotate around the rotating shaft to prevent the entire device from being overturned by the wind, and rotate the movable plate 7 to make it rotate out from the inside of the placement slot 22, and tighten one end of the pressing rod 72 against the placement slot 22, adjust the solar photovoltaic panel 71 to an inclined state to collect solar energy, and control the LED light strip 23 to light up by controlling the switch 8, so as to play a warning role at night.
