[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, an emergency traffic sign includes two symmetrically distributed signs 1. Each sign 1 has a mounting bracket 2 installed on its back end. The two mounting brackets 2 are rotatably connected at their mating ends. The vertical rod of the mounting bracket 2 has a vertical groove 7 at the end away from the sign 1. The bottom end of the vertical groove 7 and the end away from the sign 1 are both open. A rotating support mechanism is provided inside the vertical groove 7. Limiting mechanisms are installed at the top of the two signs 1. A rotating groove 3 is provided at the mating end of one mounting bracket 2. A rotating seat 4 is integrally formed at the mating end of the other mounting bracket 2. The rotating seat 4 is rotatably installed inside the rotating groove 3.

[0018] In this embodiment: when the device is not in use, the two mounting brackets 2 are folded, making it convenient for a single person to pick up and for transport in a vehicle. When the road is damaged and maintenance is required, the device is transported to the placement location, and then a single person picks it up and unfolds the mounting brackets 2 and the sign 1. After unfolding, a limiting mechanism is used to limit the mounting brackets 2 when unfolded to 180 degrees to keep the device in the unfolded state. Then, by rotating the rotating support mechanism, the rotating support mechanism is rotated out of the vertical groove 7, and the rotating support mechanism is pulled up and down to slide up and down according to the placement angle of the sign 1 until the angle of the sign 1 is appropriate. Then, the rotating support mechanism is tightened to maintain its placement stability.

[0019] Please refer to this carefully. Figure 1 and Figure 2 The limiting mechanism includes a snap-fit ​​seat 5 fixedly installed on the top of the mounting frame 2. The top of the mounting frame 2 has a snap-fit ​​groove with a superior circumferential arc. The top of the snap-fit ​​groove has an opening. A limiting rod 6 is snapped into the inner wall of the snap-fit ​​groove. The outer circumference of the limiting rod 6 is equal to the inner circumference of the snap-fit ​​groove. The two ends of the limiting rod 6 are integrally formed with anti-detachment plates on the outer side of the snap-fit ​​seat 5.

[0020] In this embodiment: when the mounting bracket 2 and the sign 1 are unfolded to 180 degrees, the limiting rod 6 is aligned with the top opening of the snap-fit ​​groove and the limiting rod 6 is pressed down. When the limiting rod 6 contacts the opening of the snap-fit ​​groove, it applies a squeezing force to the snap-fit ​​seat 5. Since the snap-fit ​​seat 5 is made of elastic plastic, the snap-fit ​​seat 5 will deform at this time until the limiting rod 6 is completely snapped into the snap-fit ​​groove. At this time, the snap-fit ​​seat 5 resets and forms a wrap around the limiting rod 6. At this time, the limiting rod 6 cannot move at will. With the help of the anti-detachment plates at both ends of the limiting rod 6, the limiting rod 6 can be prevented from falling off, thereby keeping the unfolded mounting bracket 2 and the sign 1 in a 180-degree state.

[0021] Please refer to this carefully. Figure 1 and Figure 3 The rotating support mechanism includes a rotating support 8 movably mounted inside the vertical groove 7. An outwardly protruding limiting block 10 is integrally formed on the outer side of the rotating support 8. A threaded hole is opened on the inner side of the rotating support 8. A stud 11 is threadedly connected to the inner wall of the threaded hole. A handle is integrally formed on the end of the stud 11 away from the limiting block 10. Sliding grooves 9 are opened on both sides of the vertical rod of the mounting bracket 2 for the stud 11 and the limiting block 10 to slide up and down.

[0022] In this embodiment: After the device is unfolded, the rotating support leg 8 is rotated out from the inside of the vertical groove 7. Then, according to the required angle of placement of the sign 1, the rotating support leg 8 is pulled up and down to slide. The rotating support leg 8 drives the limiting block 10 to slide up and down along the sliding groove 9. At the same time, the rotating support leg 8 drives the stud 11 to slide up and down along another sliding groove 9 until the rotating support leg 8 slides to the appropriate position. At this time, a stable placement angle is formed between the rotating support leg 8 and the sign 1, and the placement angle of the sign 1 is suitable.

[0023] Finally, by turning the handle, the stud 11 and the threaded hole will rotate until the side of the handle closest to the vertical rod of the mounting bracket 2 is pressed tightly against the vertical rod, thus completing the adjustment.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
