[0026] Embodiment

[0027] Generally, a warning sign with a warning slogan is placed on the road surface under construction and maintenance through a fixed support structure. However, the fixed support structure is not convenient for folding, so that it occupies a large amount of storage space when not in use later;

[0028] For this reason, please refer to Figures 1-4 , the present utility model provides a road maintenance marking device, including: two vertical rods 1, the bottom ends of the two vertical rods 1 are fixedly connected with water storage boxes 2, water injection pipes 21 are fixedly connected to the water inlet at the top edge of each water storage box 2, screw caps 22 are threadedly connected to the tops of the water injection pipes 21, a folding structure 3 is installed between the two vertical rods 1, and an identification cloth 4 is connected to the folding structure 3 through a plugging component;

[0029] It further includes a fixing structure 5, and the fixing structure 5 is installed on the folding structure 3.

[0030] Further, as shown in Figures 1-4As shown, it is worth specifically explaining that the folding structure 3 includes lifting channels opened on both vertical rods 1. Lifting rods 31 with an I-shaped cross-section are slidably connected in the lifting channels. Rotating rods a32 and rotating rods b33 are respectively rotatably connected to the opposite side walls of the two lifting rods 31. The rotating rods a32 and the rotating rods b33 are cross-arranged and are rotatably connected in the middle through a connecting shaft 34. The bottom ends of the rotating rods a32 and the bottom ends of the rotating rods b33 are respectively rotatably connected to the outer walls of the two vertical rods 1. Hand-tightening screws 35 are threadedly connected to the opposite side walls of the two vertical rods 1, and the ends of the hand-tightening screws 35 after being tightened are all pressed against the outside of the lifting rods 31.

[0031] When folding, the rotating rods a32 and the rotating rods b33 will respectively push the two lifting rods 31 to move upward. The setting of the hand-tightening screws 35 is to ensure the fixity of the lifting rods 31 after lifting.

[0032] Furthermore, as Figures 1-4 shown, it is worth specifically explaining that the plug-in assembly includes two symmetrically arranged insertion strips 41 fixedly connected to the back of the identification cloth 4. The cross-sections of the insertion strips 41 are all in the shape of an isosceles trapezoid. Insertion channels matching the insertion strips 41 are opened on the front side walls of the two lifting rods 31. The length of the insertion strips 41 is equal to the width of the identification cloth 4.

[0033] The setting of the insertion strips 41 enables the identification cloth 4 to be removed and replaced with different construction identification words.

[0034] Furthermore, as Figures 1-4 shown, it is worth specifically explaining that the identification cloth 4 is made of PVC-coated cloth material, and road maintenance identification words are sprayed on the front surface of the identification cloth 4.

[0035] The road maintenance identification words are not shown in the drawings and can be spray-customized according to actual needs.

[0036] Furthermore, as Figures 1-4 shown, it is worth specifically explaining that the fixing structure 5 includes inverted L-shaped positioning rods 51 fixedly connected to the front and rear side walls of the two lifting rods 31. The bottom ends of the inverted L-shaped positioning rods 51 are all in a sharp cone shape.

[0037] The setting of the inverted L-shaped positioning rods 51 can be inserted into the road ground soil in linkage with the lowering of the two lifting rods 31 to further ensure the stability of the identification device.

[0038] In summary, when using this road maintenance marking device, by pulling the two vertical rods 1 away from each other, and considering that the middle parts of the rotating rod a32 and the rotating rod b33 are rotationally connected through the connecting shaft 34, the two lifting rods 31 will slide down on the corresponding vertical rods 1 respectively until the bottom ends of the lifting rods 31 completely fit on the inner bottom wall of the lifting channel. At the same time, the bottom pointed cone parts of the four inverted L-shaped positioning rods 51 will be inserted into the soil on the ground to ensure the stability of the marking device during placement. After that, the two hand-tightening screws 35 can be tightened. Then, the two inserts 41 are respectively inserted into the insertion channels provided on the front side walls of the corresponding lifting rods 31 to cause the marking cloth 4 to be stretched. Next, the two screw caps 22 are removed, and water is respectively injected into the water storage boxes 2 to further ensure the stability of the placement of this marking device.
