发明名称 Multi-position eyebolt
摘要 For lifting loads there is provided an eyebolt with a collar swivelly mounted on a stud so as to freely rotate in a horizontal plane throughout a full 360 DEG . A lifting ring has oppositely disposed pivot pins in swivel engagement with the collar to allow the ring to pivot in a vertical arc as well as to rotate about the stud. The stud in turn is adapted to be anchored in fixed position to the load, whatever the load may be. Enlargements at free ends of the pivot pins serve to resist pulling the pins free of the collar when a heavy lifting force is applied to the lifting ring.
