[0024] The contents of the utility model are described clearly and completely below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only partial embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The hazard indication device for highway engineering shown comprises a main indication panel 1 and a sub-indication panel 2 mounted on the main indication panel.

[0026] The inner plate surface of the main indicator plate 1 is symmetrically provided with slide grooves 4 with opposite notches, and the two sides of the auxiliary indicator plate 2 are fixedly provided with slide rods 3 that cooperate with the slide grooves. The auxiliary indicator plate is inserted into the main indicator plate by inserting the slide rods into the slide grooves.

[0027] like Figure 6As shown, the outer panels of the main indicator plate 1 and the auxiliary indicator plate 2 are both provided with rectangular concave panels, and screw holes 15 for the indicator panels are processed at the four corners of the concave panels, and a warning sign 11 with a smaller outer dimension than the concave panel and a transparent plate 12 with a larger outer dimension than the warning sign are sequentially covered on the concave panel, and mounting holes are processed at the four corners of the transparent panel, and mounting screws 14 are passed through the mounting holes of the transparent panel and then screwed into the screw holes of the indicator panel, so that the transparent panel and the warning sign are clamped and mounted on the main indicator plate and the auxiliary indicator plate respectively. A compression spring 13 is mounted on the mounting screws 14. Figure 6 The transparent plate and warning sign are installed on the main indicator plate 1. The method of installing the transparent plate and warning sign on the auxiliary indicator plate 2 is the same as Figure 6 same.

[0028] like Figure 4 , Figure 5 As shown, supporting mechanisms are provided in the main indicator plate 1 and the auxiliary indicator plate 2, respectively, and placement grooves 5 for placing the supporting mechanisms are provided in the inner plate surfaces of the main indicator plate and the auxiliary indicator plate, respectively, along the longitudinal direction. The supporting mechanism includes a slot plate 6 placed in the placement groove of the main indicator plate and hinged to the main indicator plate at the bottom, a connecting plate 7 placed in the slot plate and having connection screw holes 8 processed at intervals, and a plug-in plate 9 placed in the placement groove of the auxiliary indicator plate and having connection screw holes processed at intervals at the bottom. The plug-in plate is also provided with connection screw holes processed at intervals. The plug-in plate and the connecting plate can be connected by passing the fixing bolts 10 through the connection screw holes.

[0029] In order to make the main indicator plate and the auxiliary indicator plate more stable, a counterweight block 16 is provided at the bottom of the main indicator plate 1, and the bottom edge of the main indicator plate is hinged to the counterweight block. Fixed hoops 17 can also be provided on both sides of the main indicator plate 1, through which the indicator device can be clamped on facilities such as road lamp poles and guardrails, expanding the placement and installation methods and enhancing applicability. It is best to set 4 fixed hoops as shown in the figure.

[0030] A carrying handle 18 is also provided on the top of the main indicator panel for easy hand-carrying and carrying.

[0031] The method of using the utility model is as follows: before use, first install the warning sign 11. During installation, the installation screw 14 is twisted to separate it from the main indicator plate screw hole 15, and the compression spring 13 rebounds after losing pressure to push the transparent plate 12 outward, and then the warning sign with the danger warning content and icon can be quickly installed, or the original warning sign can be removed and replaced with a new one, and then the transparent plate 12 is covered, and the installation screw 14 is screwed into the indicator plate screw hole 15, and the compression spring 13 is pressed at the same time, and the transparent plate 12 and the warning sign 11 are installed. The transparent plate 12 can not only protect the surface of the warning sign to prevent the warning sign from being scratched and damaged, but also prevent rain and reduce sunlight, and extend the use time.

[0032] After the warning sign is installed, the utility model is moved to the highway zone where warning is required by the carrying rod 18, and then the top of the auxiliary indicator plate 2 is pulled to pull the auxiliary indicator plate 2 out of the main indicator plate 1, and at the same time, the auxiliary indicator plate 2 is flipped to an inclined state, and the slot plate 6 on the rear side of the main indicator plate 1 and the plug-in plate 9 on the rear side of the auxiliary indicator plate 2 are flipped out of the placement slot 5 together, and the plug-in plate 9 is inserted into the slot plate 6. The insertion depth of the plug-in plate is adjusted as needed to adjust the inclination angle between the auxiliary indicator plate 2 and the main indicator plate 1. When the inclination angles of the auxiliary indicator plate 2 and the main indicator plate 1 are adjusted, the fixing bolts 10 are passed through the connecting screw holes 8 to fix the slot plate 6 and the plug-in plate 9, and under the gravity of the counterweight block 16, the support between the auxiliary indicator plate 2 and the main indicator plate 1 is made more stable, and the outer panels of the main indicator plate and the auxiliary indicator plate can both be used for warning. When the display panel needs to be folded after use, the plug board 9 and the slot board 6 are folded into their respective placement slots 5, and then the auxiliary indicator board 2 is turned over and put back into the main indicator board 1. At this time, the two indicator boards are combined into one, which can reduce the occupied space and is more convenient to carry and transport.
