[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 2 to 3 As shown, the lifting ring device of the utility model comprises a ring 1, a hinge shaft 2, a ring attachment 3 and a lock 4, the ring attachment 3 is symmetrically arranged on both sides of the ring 1 through the hinge shaft 2, and the lock 4 is arranged on the ring attachment 3 and abuts against both sides of the ring 1, wherein:

[0029] The lifting ring attachment 3 includes a collar 31, a fastening bolt 33 and a baffle 34, wherein the baffle 34 is fixed to the end surface of the collar 31 by the fastening bolt 33;

[0030] The locker 4 comprises a pull ring 41 , a compression spring 42 and a stop rod 43 . The compression spring 42 is sleeved on the pull ring 41 , and the stop rod 43 is arranged at the bottom of the pull ring 41 .

[0031] Furthermore, in the lifting eye device of the utility model, a mounting hole 11 is provided in the middle of the eye 1, the diameter of the hinge shaft 2 matches the diameter of the mounting hole 11, the hinge shaft 2 passes through the mounting hole 11, and the center point of the hinge shaft 2 coincides with the center point of the eye 1, so that the forces at both ends of the hinge shaft 2 are evenly distributed.

[0032] Furthermore, in the lifting eye device of the present invention, a slot 21 is provided around both ends of the hinge shaft 2, the sleeve 31 is sleeved with the hinge shaft 2, and one end of the sleeve 31 fits with the eye 1, which effectively ensures that the sleeve 31 can be disassembled and replaced, thereby effectively reducing the use cost.

[0033] Furthermore, in the lifting eye device of the present invention, the baffle 34 is arranged in an N shape, the middle part of the baffle 34 matches the slot 21, the middle part of the baffle 34 is inserted into the slot 21 and fits with the other end of the ring 31, and the fastening bolt 33 passes through the middle part of the baffle 34 and is threadedly engaged with the ring 31, thereby effectively ensuring the axial positioning of the ring 31, preventing the ring 31 from detaching from the hinge shaft 2, and effectively improving safety.

[0034] Furthermore, in the lifting eye device of the present invention, a mounting platform 5 is provided at the upper end of the baffle 34, and the pull ring 41 passes through the mounting platform 5 and the compression spring 42 and is welded to the baffle rod 43 in sequence, one end of the compression spring 42 abuts against the mounting platform 5, and the other end of the compression spring 42 abuts against the baffle rod 43, thereby preventing the wire rope from detaching from the ring 31.

[0035] Furthermore, in the lifting eye device of the present invention, the ring 31 is made of wear-resistant metal, and a U-shaped groove 32 is arranged around the middle of the ring 31, thereby effectively improving the wear resistance of the ring 31 and effectively preventing the wire rope from falling off laterally on the ring 31.

[0036] Specifically, Figures 2 to 3 As shown, when in use, the pull ring 41 is pulled to compress the compression spring 42 until the distance between the stop rod 43 and the eye 1 is greater than the diameter of the steel wire rope, and the steel wire rope is inserted into the U-shaped groove 32 on the ring 31. At this time, the pull ring 41 is released, and the compression spring 42 rebounds to make the stop rod 43 abut against the eye 1 and reset. The U-shaped groove 32 and the lock 4 provide double protection for the steel wire rope, effectively preventing the steel wire rope from escaping and improving safety. When the ring 31 is severely worn, the baffle 34 can be quickly removed to replace the ring 31, thereby effectively extending the service life.
