[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 7 According to an embodiment of the utility model, an emergency warning sign for highway maintenance includes two left-right symmetrical bottom plates 10, two warning frames 11 distributed front and back are arranged on the upper end of the bottom plates 10, a connecting rod 21 is rotatably connected between the two warning frames 11, the two warning frames 11 are staggered left and right, two left-right symmetrical support rods 12 are fixed at the lower ends of the two warning frames 11, two groups of front-back symmetrical card slots 13 are opened on the bottom plates 10, the support rods 12 are clamped with the side walls of the card slots 13, the left and right ends of the support rods 12 are rotatably connected with stabilizing blocks 14, the stabilizing blocks 14 are abutted against the left and right end surfaces of the bottom plates 10, and the left and right ends of the bottom plates 10 are fixed with stabilizing rails 15, which stabilize the bottom plates 10. The lower end of the block 14 is slidably abutted against the stabilizing rail 15, the bottom plate 10 and the lower end portion of the warning frame 11 are connected with an abutting rod 16, a receiving groove 17 is provided in the warning frame 11, an abutting frame 18 is fixedly provided on the upper side wall of the receiving groove 17, the abutting frame 18 is provided with slots of different widths, an abutting plate 19 that can slide up and down is provided in the receiving groove 17, and push springs 20 evenly distributed on the left and right are connected between the abutting plate 19 and the lower side wall of the receiving groove 17, the receiving groove 17 is opened to one side, and a limiting plate 22 is clamped on the warning frame 11 on the open side of the receiving groove 17, the limiting plate 22 is arranged on the warning frame 11 for plugging and unplugging up and down, and the abutting frame 18 corresponds to the abutting plate 19 in upper and lower concave and convex positions.

[0022] This program has the following working process:

[0023] Place the bottom plate 10 on the ground, then pull the two warning frames 11 upward from the bottom plate 10, so that the warning frames 11 are lifted upward and tilted with the support of the abutment rods 16, and insert the support rods 12 at the lower ends of the warning frames 11 into the left and right sets of slots 13, as shown in FIG. Figure 1After the warning frame 11 is placed, the user pushes the stabilizing block 14 at the lower end of the support rod 12 so that the lower end surface of the stabilizing block 14 fits with the upper end surface of the stabilizing rail 15. Figure 5 As shown, the stabilizing rail 15 is supported by the stabilizing rail 15, which limits the left and right movement of the stabilizing block 14, thereby limiting the left and right movement of the support rod 12;

[0024] The user puts multiple warning signs into the storage slot 17, so that the lower end of the warning sign abuts against the upper end surface of the abutment plate 19, and the upper end of the warning sign abuts against the lower end surface of the abutment frame 18. The thickness changes according to the number of warning signs put into the storage slot 17, so that the abutment frame 18 can abut different numbers of warning signs corresponding to the slots of different widths on the abutment frame 18. The abutment plate 19 is supported by the push spring 20, so that the abutment plate 19 can abut against multiple warning signs.

[0025] When folded, the abutment rod 16 is used as support to make the two inclined warning frames 11 horizontally arranged on the upper end of the bottom plate 10 fit together, thereby reducing the occupied space and facilitating transportation;

[0026] When the warning frame 11 is exposed to wind, the two inclined left and right warning frames 11 can generate downward pressure when exposed to wind on both sides, thereby preventing the warning frame 11 set on one side from tipping over in the leeward state, thereby improving the stability of the warning frame 11 when working.
