Description

Technical Field

[0001] The utility model belongs to the technical field of protective components, and more specifically, particularly relates to a safety guardrail which is easy to disassemble and assemble. Background Art

[0002] There are many types of sports. When playing sports in a stadium, different sports require different sports venues. In order to avoid mutual influence, different sports venues need to be separated by safety fences. Support rods support the guardrails to divide the stadium into different sports venues. At the same time, the safety fences need to be easy to disassemble and dismantle, and they need to be removed when the sports are completed.

[0003] According to CN202221207506.6, the utility model discloses a stadium safety guardrail that is easy to disassemble and assemble, including a support rod and a guardrail plate, a first fixing assembly is provided between the support rod and the guardrail plate, the support rod is fixedly connected to the guardrail plate through the first fixing assembly, a plurality of rectangular holes are provided inside the guardrail plate, the bottom end of the support rod is fixedly connected with a fixing block, the bottom end of the fixing block is provided with a universal wheel, and a positioning mechanism is provided on the lower side of the support rod. The utility model adopts the above structure, and by setting the first fixing assembly, when it is necessary to separate the guardrail plate from the support rod, the dust cover is removed by the handle, and then the first fixing screw is rotated to make it leave the support rod and the guardrail plate, so that the separation can be completed, which is convenient for the transportation of the guardrail and the later maintenance of the guardrail, and solves the problem that the traditional integrated guardrail is convenient for transportation but inconvenient for maintenance, improves the practicality of the safety guardrail, and has a better use effect.

[0004] Based on the above, the existing safety guardrails are generally supported by support rod structures. Transporting the safety guardrails requires workers to lift the safety guardrails for transport, which consumes a lot of physical strength. In order to increase the protective height of the safety guardrails, a guard plate structure is generally added. Since the guard plate structure is high, it is inconvenient to store and transport the safety guardrails. Utility Model Content

When the safety guardrail is transported, the safety guardrail is directly pushed to move, which avoids the problem that the staff needs to lift the safety guardrail for transportation, saving the staff's physical strength in transportation. When the safety guardrail is used, the lifting motor shaft rotates to drive the lifting guard plate to slide, and the lifting guard plate slides to a high place, thereby increasing the protective height of the safety guardrail, avoiding the problem that the high protective height of the safety guardrail affects the storage and transportation of the safety guardrail, and facilitating the use and storage of the safety guardrail.
