Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a detachable pull rod connecting device. Background Art

[0002] Currently, temporary lighting and pressure pipes in the building decoration industry are primarily installed using three methods: ceiling-mounted angle steel frames (or hanging bars), wall-mounted triangular angle steel frames, and ground-mounted independent angle steel frames (greater than 1800 mm). Regardless of the method, installation cannot be completed in one go, requiring at least two relocations or changes to the design to meet construction requirements. This not only impacts construction schedules, increases costs, and inconveniences in installation and removal, but also poses significant safety risks. The easy-pull sling overcomes the shortcomings of these lifting methods, summarizing their advantages and developing its own unique features: simple installation and disassembly; standardized construction and safe use; reusable, energy-efficient, and environmentally friendly; shortened construction timelines and reduced costs. It is not only used in building interior decoration projects, but also has widespread application in road and bridge construction, industrial plants, mines, and other engineering industries. It can also be used in everyday home and office environments, offering a wide range of applications. Utility Model Content
