[0025] See also Figure 1-4 In the embodiment of the utility model, a safety warning sign includes a U-shaped frame 1, and both side walls of the U-shaped frame 1 are provided with card grooves 12. A warning sign body 11 is slidably connected in the U-shaped frame 1, and both ends of the warning sign body 11 are respectively slidably connected in the two card grooves 12. The top of the U-shaped frame 1 is fixedly connected with a cover plate 10 by two bolts 9. Two second threaded holes 8 are provided at the top of the U-shaped frame 1. The bottoms of the two bolts 9 penetrate the side walls of the cover plate 10 and are slidably connected to the cover plate 10. One ends of the two bolts 9 are respectively threadedly connected in the two second threaded holes 8. The bottom of the U-shaped frame 1 is connected to two bottom plates 5 through a disassembly device. The bottoms of the two bottom plates 5 are rotatably connected to two support rods 6 through a rotating shaft. A fixing device is provided between the two support rods 6 at the bottom of the two bottom plates 5. A fixing block 13 is fixedly connected to the side wall of the lower end of the four support rods 6, and each side wall of the fixing block 13 is provided with a fixing hole.

[0026] See also Figure 1-3 The disassembly device includes two first threaded holes 2, which are both opened on the bottom side walls of the U-shaped frame 1. Threaded rods 3 are threadedly connected in the two first threaded holes 2. Corresponding first threaded holes 2 are extended from the bottoms of the two threaded rods 3. Two handles 4 are fixedly connected to the side walls of the two threaded rods 3. The bottoms of the two threaded rods 3 are respectively rotatably connected to the top side walls of the two bottom plates 5. By screwing the two threaded rods 3 into the two first threaded holes 2, the bottom plates 5 and the support rods 6 are fixed to the bottom of the U-shaped frame 1.

[0027] See also Figure 1-3 The surfaces of the four handles 4 are all provided with anti-skid patterns to prevent slipping when the handles 4 are turned.

[0028] See also Figure 1-4The two fixing devices include two fixing rods 14, which are respectively located between the two supporting rods 6 at the bottom of the two bottom plates 5, and the side walls of each supporting rod 6 are fixedly connected with a plurality of snap rings 7. The plurality of snap rings 7 on the side walls of the two supporting rods 6 at the bottom of the two bottom plates 5 are symmetrically arranged. The side walls of the two fixing rods 14 are fixedly connected with two limiting rods 15, and the side walls of the four limiting rods 15 are provided with sliding grooves 17. The side walls of each sliding groove 17 are fixedly connected with a spring 16, and one end of each spring 16 is fixedly connected with a block 18, and each block 18 is slidably connected to the corresponding sliding groove 17, and one end of each block 18 extends out Corresponding to the sliding groove 17, the four limit rods 15 are respectively located in different clamping rings 7, and the two limit rods 15 on the side wall of the fixing rod 14 are inserted into the two clamping rings 7 parallel to the side walls of the two support rods 6 at the bottom of the bottom plate 5. When the limit rod 15 is inserted into the clamping ring 7, the clamping ring 7 will squeeze the inclined side wall of the block 18, so that the block 18 moves into the sliding groove 17, and the block 18 squeezes the spring 16 at the same time, so that the spring 16 is in a stressed state. When the block 18 passes through the clamping ring 7, the block 18 is separated from the side wall of the clamping ring 7, and the spring 16 drives the block 18 to reset, thereby fixing the limit rod 15, and the two support rods 6 can be fixed.

[0029] See also Figure 4 The side wall at one end of each block 18 is arranged in an inclined shape. When the block 18 touches the side wall of the snap ring 7, the side wall of the snap ring 7 will squeeze the inclined side wall of the block 18, so that the block 18 automatically moves into the sliding groove 17, thereby eliminating the need to manually press the block 18 to move, which is more convenient.

[0030] See also Figure 1-3 The two bolts 9 and the two threaded rods 3 are both made of stainless steel to prevent the two bolts 9 and the two threaded rods 3 from being affected by rust.

[0031] The working principle of the utility model is as follows: by screwing the two threaded rods 3 into the two first threaded holes 2, the bottom plate 5 and the support rod 6 are fixed to the bottom of the U-shaped frame 1, and then the two limiting rods 15 on the side walls of the fixing rod 14 are inserted into the two clamping rings 7 parallel to the side walls of the two support rods 6 at the bottom of the bottom plate 5. When the limiting rods 15 are inserted into the clamping rings 7, the clamping rings 7 will squeeze the inclined side walls of the clamping block 18, so that the clamping block 18 moves into the sliding groove 17, and the clamping block 18 squeezes the spring 16 at the same time, so that the spring 16 is in a stressed state. When the clamping block 18 passes through the clamping ring 7, the clamping block 18 is separated from the side wall of the clamping ring 7, and the spring 16 drives the clamping block 18 to reset, thereby fixing the limiting rods 15, that is, the two support rods 6 are fixed. By inserting the two limiting rods 15 on the side walls of the fixing rod 14 into the two clamping rings 7 of different heights, not only the two support rods 6 can be fixed, but also the height of the warning sign body 11 can be adjusted.

[0032] When the warning sign body 11 needs to be replaced, the two bolts 9 can be removed by unscrewing them to release the fixing of the bolts 9 to the cover plate 10, and then the cover plate 10 can be removed, and the warning sign body 11 can be lifted up to take out the warning sign body 11, and then the new warning sign body 11 can be stuck in the two slots 12, and then the cover plate 10 can be restored, and the warning sign body 11 can be quickly replaced.
