Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a spliced ​​metal guardrail. Background Art

[0002] Metal guardrails are a common type of traffic facility and fence, commonly used as traffic safety facilities on highways, freeways and urban roads to separate lanes, guide traffic flow, and protect pedestrians and vehicles from accidents. In construction sites, road construction sites and other places, metal guardrails can be used to restrict people and vehicles from entering dangerous areas to ensure site safety. In factories, machinery and equipment areas and other places that require safe isolation, metal guardrails can be used to restrict people from entering dangerous areas to protect the safety of workers.

[0003] After searching, the patent number "CN220815172U" mentioned in the text that "the utility model discloses a spliced ​​metal guardrail, including a support box and an adjustment component; two support boxes are provided, a railing component is installed between the two support boxes, and a fastening component is installed on the upper side of the support box; the adjustment component includes a bidirectional screw, a sliding rod and a connecting box, four corresponding strip openings are opened on the left and right sides of the support box, and the inner side of the strip opening is slidably connected with the connecting box, and the upper sides of the two connecting boxes on the left are both provided with threaded holes, and the threads of the two threaded holes are opposite, and the inner threads of the two threaded holes are connected with bidirectional screws, and the bidirectional screw is welded by two threaded rods with opposite threads, and the bidirectional screw is rotatably connected to the left end of the inside of the support box, and the two on the right are connected to the left end of the support box. Each connection box has a connection hole on its upper side, which can quickly disassemble the vertical rod, facilitate its replacement or repair, and avoid replacing the entire guardrail. "When in use, by setting the adjustment component, when the vertical rod is damaged, the bolt on the right side can be removed, and then the two-way screw on the right side is rotated by the right turntable to gradually move the two square steel pipes away. After the two square steel pipes are gradually away, the damaged vertical rod can be removed. The guardrail does not need to be disassembled as a whole during the whole process, which is not only efficient, but also greatly reduces the cost of guardrail maintenance. However, the main structure of the device is relatively uniform and needs to be moved as a whole. A single vertical rod cannot be taken out and installed separately without affecting the installation of other vertical rods, which has certain limitations. Utility Model Content
