[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-9 , the present utility model provides a technical solution: Specific embodiment one;

[0033] A portable warning device for road maintenance, comprising: the longitudinal section of the first support frame 1 is in a "U" - shaped structure, and the first support frame 1 is placed on the ground; a limiting mechanism is arranged inside the first connecting block 2, where the limiting mechanism includes an adjusting rod 3, a second connecting block 4, a positioning rod 5, a magnet 6 and a connecting plate 7. The first connecting block 2 is threadedly connected to the adjusting rod 3, and the second connecting block 4 and the magnet 6 repel each other magnetically; the warning board 12 is connected to the support plate 10 by a card slot, and the material of the support plate 10 is magnetic;

[0034] When the device needs to be used, as shown in Attached Figure 1 、Attached Figure 2 and Attached Figure 3 as shown, rotate the second support frame 9 on the first connecting block 2 so that the second support frame 9 forms an angle with the first support frame 1. The first support frame 1 and the second support frame 9 support the support plate 10 to ensure the stability of the support plate 10. Since the second support frame 9 and the first connecting block 2 are connected by a damping rotating shaft, the stability of the second support frame 9 can be ensured; Specific Embodiment Two;

[0036] The existing warning devices for road maintenance are inconvenient to carry, and the installation and disassembly are cumbersome. To solve this technical problem, in this embodiment, as shown in Attached Figure 1 、Attached Figure 4 -Attached Figure 9 as shown, rotate the adjusting rod 3 threadedly connected to the first connecting block 2 to adjust the height of the adjusting rod 3. The adjusting rod 3 pushes the second connecting block 4 closely attached below it. Since the second connecting block 4 is made of a material that attracts the magnet 6 with opposite polarity, when the adjusting rod 3 is at a high position, the second connecting block 4 fits with the magnet 6, and the positioning rod 5 fixed on the front side of the second connecting block 4 is located inside the first connecting block 2. Rotate the adjusting rod 3 to make it move downward. The adjusting rod 3 pushes the second connecting block 4 closely attached below it, separating the second connecting block 4 and the magnet 6. The positioning rod 5 fixed on the front side of the second connecting block 4 slides inside the first connecting block 2, and the positioning rod 5 is connected to the connecting plate 7 inside the first connecting block 2 by a card slot, and the first connecting block 2 can be fixed on the connecting plate 7;

[0037] As shown in Attached Figure 5As shown in the figure, when it is necessary to store the first support frame 1 and the second support frame 9, rotate the adjusting rod 3 to lift the adjusting rod 3. The second connecting block 4 and the magnet 6 are magnetically adsorbed, so that the second connecting block 4 and the positioning rod 5 are received into the first connecting block 2. The positioning rod 5 is disengaged from the card slot connection with the connecting plate 7. Then, slide the first connecting block 2 connected to its card slot on the connecting plate 7 to adjust the height of the first connecting block 2, so that the first support frame 1 and the second support frame 9 are stored behind the support plate 10. Positioning holes 8 are symmetrically arranged up and down on the rear side of the connecting plate 7. Connect the positioning rod 5 to the upper positioning hole 8 in the same way as above, so that the first connecting block 2 is fixed above the connecting plate 7, which can reduce the floor area of the first support frame 1 and the second support frame 9; Specific Embodiment Three;

[0039] The existing warning devices for highway maintenance are not convenient to replace according to the warning content. To solve this technical problem, in this embodiment, as shown in the attached Figure 2 and attached Figure 3 As shown in the figure, place the warning board 12 on the front side of the support plate 10, so that the warning board 12 and the support plate 10 are magnetically connected, and fix the warning board 12 on the support plate 10. The lower part of the warning board 12 is closely attached to the support bar 11 fixed on the lower front side of the support plate 10. The support bar 11 supports the warning board 12 to prevent the warning board 12 from falling. When it is necessary to replace the warning board 12, remove the warning board 12 to make it disengage from the magnetic connection with the support plate 10.

[0040] This is the entire working process of the portable warning device for highway maintenance. The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0041] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
