AI Technical Summary
When the safety rope comes into contact with the existing safety buckle during use, the anti-derailment strip may move inward into the safety buckle under stress, causing the safety buckle to be in an open state and creating a risk of the safety rope falling off, posing a safety hazard.
A safety buckle for preventing detachment is designed, comprising a safety buckle assembly and an anti-detachment assembly. By setting a second protrusion on the stop bar and threading a fixing nut, the stop bar is ensured to be fixed on the second protrusion, preventing the stop bar from moving inward when subjected to external force. Combined with a spring and hook structure, it prevents detachment caused by misoperation.
It effectively prevents the safety rope from falling off, improves safety during use, avoids the risk of the safety rope falling off due to misoperation, and enhances safety and stability.
