[0019] Embodiment:

[0020] like Figure 1-Figure 5As shown, a safety guardrail comprises a railing 1, wherein the number of the railings 1 is two, a folding frame 2 is provided between the two railings 1, and is used to fold the two railings 1, a storage box 3 is installed on one of the railings 1, a protective net 5 is stored inside the storage box 3, the protective net 5 is elastic and can be stretched, one end of the protective net 5 is outside the storage box 3 and is connected to a vertical rod 4, a tensioning mechanism is installed on the top and bottom of the other railing 1, a roller is rotatably connected to the inside of the storage box 3, the protective net 5 is rolled on the outside of the roller, a torsion spring is provided at the rotation connection between the roller and the inside of the storage box 3, the torsion spring can automatically roll up the protective net 5 without manual rolling, and the top and bottom of the vertical rod 4 are fixed A pull ring 7 is fixedly installed, and a hook 8 is provided on the pull ring 7. The tensioning mechanism includes a winding box 6 fixedly installed on the railing 1, and an empty slot 15 is opened on the inner side of the winding box 6. A winding shaft 10 is movably connected to the inner side of the empty slot 15, and a pull rope 9 is wound around the outer side of the winding shaft 10. One end of the pull rope 9 extends to the outer side of the winding box 6 and is connected to the end of the hook 8. One end of the winding shaft 10 is located on the outer side of the winding box 6 and is connected to a turning handle. The other end of the winding shaft 10 is rotatably connected to a rotating block 12, and one end of the rotating block 12 is fixedly connected to a spring 13. When the winding shaft 10 rotates, it will not drive the rotating block 12 and the spring 13 to rotate, and one end of the spring 13 is fixedly connected to the inner side of the empty slot 15. The two railings 1 can be folded by the folding frame 2 for easy transportation. When the two railings 1 are unfolded, the vertical rod 4 is pulled outward, the protective net 5 rolled on the surface of the roller is unfolded, and then the reel 10 is pressed inward, the spring 13 is compressed, and the limit tooth 14 leaves the inner side of the limit groove 11. At this time, the reel 10 can be rotated, and the pull rope 9 is pulled outward. The length of the pull rope 9 depends on the situation, and then the reel 10 is released. The spring 13 pushes the reel 10 to move to one side back to its original position, and the limit tooth 14 is stuck in the inner side of the limit groove 11. It cannot rotate, and the operation is completed; the two railings 1 are designed to be foldable to each other for easy transportation, and the protective net 5 can be stored and unfolded. The protective net 5 is made of elastic material. When the protective net 5 is tightened, it can play a good protective support role and improve safety. Some publicity or warning slogans can be hung on the protective net 5, which is very convenient and can adapt to the different distances between the two railings 1, and has better applicability; the setting of the tensioning mechanism makes it easy to stretch the protective net 5, and the length of the pull rope 9 can be adjusted, and it can cooperate with the protective net 5 for fine-tuning.

[0021] like Figure 3 , Figure 4 As shown, in other embodiments, the present embodiment discloses that a limiting tooth 14 is provided on the outer surface of the empty slot 15 away from the rotating block 12, and a limiting slot 11 matching with the limiting tooth 14 is opened on the inner side of the empty slot 15; the limiting tooth 14 is engaged in the limiting slot 11, and can limit the rotation of the winding shaft 10. When the winding shaft 10 moves laterally, it can drive the limiting tooth 14 to move laterally away from the inner side of the limiting slot 11, thereby releasing the restriction on the winding shaft 10.

[0022] like Figure 1 As shown, in other embodiments, this embodiment discloses that a base is threadedly connected to the bottom of the railing 1, a groove is opened inside the base, the inside of the groove is filled with sand, a sand discharge port is provided on one side of the bottom of the base, and a cover is screwed on the sand discharge port. Sand or water can be filled into the base to increase the weight and improve stability, and it can be discharged during transportation to reduce weight and facilitate transportation.

[0023] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
