AI Technical Summary
Traditional expansion bolts require a wrench to tighten the nut or screw end, which is inconvenient and affects construction efficiency. Furthermore, additional connectors are needed to connect the ceiling threaded rod after fixing.
A high-efficiency ceiling expansion bolt was designed, comprising a threaded screw, a circular plate assembly, a force-bearing assembly, a nut assembly, and an expansion mechanism. It is directly screwed into the lifting screw using a power tool via a hexagonal screwdriver, and anti-slip grooves are provided on the expansion tube to enhance stability.
It enables rapid expansion and fixing using power tools, improving construction efficiency, and allows direct connection of ceiling threaded rods without additional connectors, enhancing the stability and installation quality of the expansion bolts.
