DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-8 A warning sign comprises a first frame 1, a first warning plate 2, a second frame 3 and a second warning plate 13. A first placement groove 15 is provided on the inner surface of the first frame 1. The first warning plate 2 is slidably installed in the first placement groove 15. A first limiting bolt 8 is threadedly penetrated on one side of the first frame 1. A sleeve 9 is fixedly installed on the top of the first frame 1. A rotating shaft 10 is fixedly sleeved on the inner wall of the sleeve 9. The top of the rotating shaft 10 is fixedly connected to the second frame 3. A second placement groove 16 is provided on the inner surface of the second frame 3. The second warning plate 13 is slidably installed in the second placement groove 16. A first limiting bolt 8 is threadedly penetrated on one side of the second frame 3.

[0026] In the utility model, a limiting block 11 is fixedly installed at the bottom of the second frame 3 , there are two limiting blocks 11 , and a limiting strip 12 is slidably installed on the two limiting blocks 11 together.

[0027] In the utility model, both sides of the bottom of the first frame 1 are hinged with first support rods 5 through hinges 4, and the inner surface of the first support rod 5 is slidably mounted with a second support rod 6.

[0028] In the present invention, the second limiting bolts 14 are threadedly penetrated on the opposite sides of the two first supporting rods 5 , and the second limiting bolts 14 abut against the second supporting rods 6 .

[0029] In the utility model, a stabilizing block 7 is fixedly installed at the bottom of the second supporting rod 6 , and there are four stabilizing blocks 7 , which are divided into two groups and correspondingly distributed on the two second supporting rods 6 .

[0030] In the present invention, the two first support rods 5 are parallel to each other, and the two second support rods 6 are parallel to each other.

[0031] When the utility model is in use, the first warning plate 2 is placed in the first placement groove 15 in the first frame 1, the first limiting bolt 8 is tightened, the second warning plate 13 is placed in the second placement groove 16 in the second frame 3, the second limiting bolt 8 is tightened, the limiting strip 12 is pulled up, the second frame 3 is rotated, and the rotating shaft 10 rotates in the sleeve 9, so that the angle between the second frame 3 and the first frame 1 is a right angle, and then the limiting strip 12 is dropped, the limiting strip 12 slides into the limiting block 11, and the limiting strip 12 is engaged on both sides of the first frame 1, and the first frame 1 and the second frame 3 are fixed.
