[0002] Lifting rings are usually used for lifting, pulling, fixing and other operations. They can withstand large pulling forces to ensure the safety and stability of the operation. In addition, lifting rings are also used in sporting goods and outdoor sports.

[0003] Traditional lifting rings are usually circular in structure. In order to facilitate the rotation and adjustment of the objects suspended by the lifting rings, the lifting rings are usually also equipped with a rotating shaft. The objects or equipment to be suspended are connected to the other end of the rotating shaft. After being suspended on the rope using the lifting rings, they can be freely rotated and adjusted. However, in actual application, it is found that the lifting rings are directly suspended on the ropes, and the force point is single. When the objects or equipment are affected by external forces, the lifting rings can easily slide along the ropes, affecting the use of the objects or equipment, and posing certain safety hazards. For this reason, the present application proposes a rotating anti-slip tie ring. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] A rotating anti-slip fastening ring, such as Figures 1-4 As shown, it includes a ring body 1, which has an opening on the side of the ring body 1 to facilitate hanging the ring body 1 on the sling, and the bottom end of the ring body 1 is rotatably connected to a connecting wire column 3, and a rotating connecting block 2 is provided at the bottom end of the ring body 1. The connecting wire column 3 is rotatably assembled at the bottom end of the ring body 1 through the rotating connecting block 2, and the rotating connecting block 2 includes a connecting block 14 fixedly connected to the bottom end of the ring body 1 and a shell 15 and a bottom plate 16 provided at the bottom of the connecting block 14. The shell 15 and the bottom plate 16 are fixedly connected, and the connecting wire column 3 is fixedly connected to the bottom of the bottom plate 16. The lower surface of the connecting block 14 is provided with a boss 17 that is rotatably embedded in the shell 15, and the boss 17 is set to an inverted T-shaped structure. Through this structural method, after the ring body 1 is hung on the sling, the object or equipment to be suspended is threadedly connected to the connecting wire column 3, and the suspended object or equipment can be freely rotated to adjust the angle by utilizing the rotation cooperation between the boss 17 at the bottom of the connecting block 14 and the shell 15.

[0024] In this embodiment, a ball 18 is embedded between the boss 17 and the inner top wall of the housing 15 to facilitate rotational adjustment.

[0025] In a further embodiment, a locking assembly 4 is provided on both sides of the ring body 1. The locking assembly 4 includes a horizontal arm 7 fixed horizontally on both sides of the bottom end of the ring body 1. The end of the horizontal arm 7 away from the ring body 1 is vertically bent upward and provided with a vertical arm 8. A screw rod 9 is vertically threaded through the vertical arm 8, and a locking block 10 is rotatably connected to the top of the screw rod 9. The screw rod 9 is rotated on both sides of the ring body 1 to push the locking block 10 upward, so that the locking block 10 is pressed against the sling suspended by the ring body 1. Continuous twisting of the screw rod 9 pushes the locking block 10 upward relative to the ring body 1, so that the pair of locking blocks 10 are distributed higher than the ring body 1. At this time, the sling is pressed against the inner top wall of the ring body 1, and the pair of locking blocks 10 support the sling. The sling is subjected to force at three points, and the three force points of the sling are distributed in a triangular shape. When the sling is taut, the ring body 1 can be effectively locked and positioned on the sling, solving the problem that the ring body 1 is prone to sliding along the sling after the screw rod 3 is connected to suspend objects or equipment, posing a safety hazard.

[0026] In this embodiment, a reinforcement plate 13 is fixedly connected between the upper surface of the horizontal arm 7 and the side wall of the vertical arm 8. The reinforcement plate 13 is set as a triangular structure to play a reinforcing role. A handle 11 is set at the bottom end of the screw rod 9 to facilitate turning the screw rod 9 to rotate.

[0027] In this embodiment, the locking block 10 is configured as a semicircular structure, and the arc concave surface of the locking block 10 is distributed upward, which is conducive to the locking block 10 pushing the extension and contraction of both sides of the ring body 1 upward to lock it.

[0028] In this embodiment, circular protrusions 5 are provided on both sides of the top of the ring body 1. These protrusions 5 are integrally connected to the ring body 1. The concave surfaces of the protrusions 5 face downward and align with the inner wall of the ring body 1, increasing the force-bearing area between the ring body 1 and the sling and reducing shear forces on the sling. A first rubber gasket 6 is embedded in the concave surfaces of the protrusions 5 and the inner top wall of the ring body 1. A second rubber gasket 12 is embedded in the concave surface of the locking block 10 to reduce wear on the sling.

[0029] The working principle of the present invention is as follows: when in use, the ring body 1 is hung on the sling, and the object or equipment to be suspended is threadedly connected to the connecting screw column 3. The bottom boss 17 of the connecting block 14 is rotated with the shell 15, so that the suspended object or equipment can be freely rotated to adjust the angle. The screw rods 9 on both sides of the ring body 1 are rotated to push the locking block 10 upward, so that the sling suspended by the ring body 1 is embedded in the semicircular locking block 10. Then, the screw rod 9 is continuously turned to push the locking block 10 upward relative to the ring body 1, so that the pair of locking blocks 10 are distributed higher than the ring body 1. At this time, the sling is pressed against the top wall of the ring body 1, and the pair of locking blocks 10 support the sling. The sling is stressed at three points, and the three stress points of the sling are distributed in a triangular shape. When the sling is tightened, the ring body 1 can be effectively locked and positioned on the sling, solving the problem that the ring body 1 is easy to slide along the sling after the connecting screw column 3 is used to suspend the object or equipment, posing a safety hazard.
