When the lower folding plate 4 is in the expanded state, it is positioned by the snap connection between the first latch 31 and the second latch 41. Since the lower ends of the upper folding plates 3 of the first panel 1 and the second panel 2 are respectively connected to the lower folding plate 4 through the first folding positioning structure, and the first folding positioning structure includes at least one first rotating component and at least one first positioning component, the lower folding plates 4 of the first panel 1 and the second panel 2 can be rotated and folded to the outside of the upper folding plate 3 by the first rotating component in the folded state, thereby shortening the overall space occupied by the warning sign, reducing the difficulty of storage, and facilitating packaging or storage. Compared with the prior art, the utility model does not need to increase the thickness of the upper folding plate 3, the structure is lighter and easier to carry, and the lower folding plates 4 of the first panel 1 and the second panel 2 are in the unfolded state. The upper and lower folding plates can be positioned by the snap connection between the first snap fastener 31 and the second snap fastener 41 of the first positioning assembly, so that the upper and lower folding plates are stably positioned in the same plane, with a simple structure, convenient folding or unfolding, and convenient operation; the positioning by the snap connection between the first snap fastener 31 and the second snap fastener 41 can effectively reduce the friction loss of the structure and extend the service life of the warning sign compared with the positioning by spring snap fasteners in the prior art; the upper ends of the two upper folding plates 3 are connected by the second folding positioning structure, so that the warning sign can be further folded, further reducing the space occupied by the entire warning sign, making it more convenient to pack, store or carry, and having strong practicality. In addition, the first panel 1 and the second panel 2 are arranged at an angle, and the distance between the lower ends of the first panel and the second panel is greater than the distance between the upper ends, so that the warning sign is in a herringbone structure as a whole, which is more stable and has stronger wind resistance than the traditional warning sign structure, and is not easily pushed away from the original work location.

The first buckling portion 311 and the first limiting portion 312 are connected and fixed by the first connecting portion 313, and the first buckling portion 311 is protruded from the side of the first connecting portion 313 to form a first buckling surface 316 on the side of the first buckling portion 311 close to the first limiting portion 312, and the first limiting portion 312 is protruded from the side of the first connecting portion 313 to form a first limiting surface 317 on the side of the first limiting portion 312 close to the first buckling portion 311. The second buckling surface 411 and the second limiting surface 412 are respectively provided on both sides of the second buckle 41. When the first buckle 31 and the second buckle 41 are buckled and connected, the first buckling surface 316 abuts against the second buckling surface 411, and the first limiting surface 317 abuts against the second limiting surface 412 to limit. It is convenient and reliable, and the upper folding plate 3 and the lower folding plate 4 can be positioned on the same horizontal plane.

[0037] like Figure 6-8 As shown, in order to facilitate the fastening of the first fastener 31 and the second fastener 41, a first guide surface 314 for guiding the fastening connection of the first fastener 31 and the second fastener 41 is provided on the side of the first fastener portion 311 away from the first limiting portion 312, and the distance between the first guide surface 314 and the first fastening surface 316 gradually increases from the side of the first fastening surface 316 away from the first connecting portion 313 to the side close to the first connecting portion 313. When the warning sign is unfolded, the inner side surface of the first fastening portion 311 acts as the first fastening surface 316 and fits with the second fastening surface 411 to form the first positioning of the upper folding plate 3 and the lower folding plate 4. The first guide surface 314 is provided to facilitate rapid unfolding and positioning, and can effectively reduce the friction loss of the first positioning component and increase the service life of the warning sign.

[0038] In another embodiment, if Figure 4 and Figure 6-7 As shown, the first buckling portion 311 is arranged on one side of the first connecting portion 313 protruding along the thickness direction of the first connecting portion 313, and the first limiting portion 312 is arranged on both sides of the first connecting portion 313 protruding along the width direction of the first connecting portion 313.

The arrangement of the first reinforcing portion 315 improves the structural strength of the first snap-fitting portion, making it more solid and durable. The distance between the second guide surface 413 and the second fastening surface 411 gradually increases from the first fastening surface 316 to form an inclined surface, which further facilitates guiding the first fastening member to pass through the fastening channel 42 and fasten with the second fastener 41. In this embodiment, the slope of the inclined surface is the same as that of the first guide surface 314, and the two guide surfaces are parallel to each other to facilitate the cooperation between the first fastener 31 and the second fastener 41.
