[0002] The outdoor mounting rack for LED screen is a core structural component for supporting large display screen to stably operate in open-air environment, which is usually composed of high-strength aluminum alloy or galvanized steel frame, and is designed by mechanical simulation optimization to adapt to load distribution and deformation compensation under different climate conditions. The assembly and fine adjustment are realized by using pre-installed positioning pins and anti-loosening bolts, and the waterproof sealing rubber strip and heat dissipation channel design are matched to consider the protection level and heat management efficiency. The modern mounting rack adopts prefabricated assembly process, which reduces the high-altitude operation time and improves the installation safety through standardized interface and lightweight structure. However, the traditional mounting rack still has significant limitations in actual construction: the installation process highly depends on hoisting equipment and multi-person collaborative operation, and there is a lack of reliable temporary fixing device after the module is hoisted to the rack body, so the operating personnel need to manually right the module and tighten the bolts one by one in the suspended state, which not only increases the falling risk and time consumption, but also easily causes the module to deviate due to wind or vibration. In addition, the repeated disassembly and adjustment are needed when the pre-positioning accuracy of the rack body is insufficient, which further aggravates the complexity and safety hazards of high-altitude operation, and restricts the construction efficiency and cost control of large-scale display screen projects.
