[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A rotating eye-shaped lifting ring load adjustment device includes a lifting plate 1 with a groove 2 on it. A lifting ring body 3 is slidably connected to the inner wall of the groove 2. A nut 4 is fitted onto the outer surface of the lifting ring body 3, with the top of the nut 4 abutting against the lifting plate 1. A frame 5 is slidably connected to the top of the lifting plate 1, and the lifting ring body 3 is slidably connected to the inner wall of the frame 5. An electric telescopic rod 6 is fixedly connected to the outer surface of the lifting plate 1 near the frame 5. In use, each eye-shaped lifting ring is simultaneously inserted into the groove 2 and the frame 5, and the nut 4 is tightened to prevent them from falling off. The lifting ring body is then adjusted... 3. The pull ring 12 of the hook to be connected to the eye-shaped lifting ring is fixed. The electric telescopic rod 6 is started to drive the two frames 5 to move closer to each other, which in turn drives the four lifting ring bodies 3 to move closer to each other. The lever arm is changed by the translation of the lifting ring bodies 3 on the lifting plate 1, thereby adjusting the load of each lifting point and achieving the load adjustment effect. Among them, the movement of the two frames 5 drives the four lifting ring bodies 3 to move closer to each other. By changing the distance between the lifting points, the load adjustment effect is achieved. As the distance between the lifting points decreases, the lever arm length of the weight of the object on the lifting point increases, and the resultant force borne by the lifting ring body 3 will decrease.

[0017] In this embodiment, preferably, the lifting plate 1 has a positioning groove 7 at the top near the slide 2, and the bottom of the lifting ring body 3 is fixedly connected to a positioning block 8. The positioning block 8 is slidably connected to the inner wall of the positioning groove 7. When the lifting ring bodies 3 move towards each other during use, the positioning block 8 slides inside the positioning groove 7. The positioning groove 7 is set on both sides of the slide 2 to facilitate the smooth sliding of the lifting ring body 3.

[0018] In this embodiment, preferably, the lifting plate 1 has a positioning groove 9 near the top of the frame 5, and a positioning block 10 is fixedly connected to the bottom of the frame 5. The positioning block 10 is slidably connected to the inner wall of the positioning groove 9. In use, the electric telescopic rod 6 drives the two frames 5 to move towards each other, thereby adjusting the distance between each lifting ring body 3. When the frames 5 move towards each other, the positioning block 10 slides inside the positioning groove 9 to ensure smooth sliding.

[0019] In this embodiment, preferably, the lifting ring body 3 includes an upper ring body 11, a pull ring 12 is fixedly connected to the top of the upper ring body 11, and a lower ring body 13 is rotatably connected to the bottom of the upper ring body 11. Bolts 14 are inserted into the upper ring body 11 and the lower ring body 13. In use, the hook is connected to the pull ring 12. During lifting, the pull ring 12 and the upper ring body 11 and the lower ring body 13 rotate. The lifting ring body 3 can rotate to adapt to the angle change of the lifting ring body 3 during the lifting process. In addition, a nut 4 is fitted on the outer surface of the bolt 14. After the bolt 14 is installed into the lifted heavy object, the nut 4 is tightly pressed against the surface of the heavy object.

[0020] In this embodiment, preferably, the lower ring body 13 has an annular groove 15, and the bottom of the upper ring body 11 is fixedly connected to an annular retaining strip 16. The annular retaining strip 16 is slidably connected to the inner wall of the annular groove 15. In use, the upper ring body 11 and the lower ring body 13 rotate, causing the annular retaining strip 16 to slide on the inner wall of the annular groove 15. The annular retaining strip 16 is always engaged in the annular groove 15, restricting the upper ring body 11 and the lower ring body 13 to only rotate, ensuring that the stress is transmitted vertically along the lifting ring body 3, and assisting in load adjustment.

[0021] In this embodiment, preferably, a stop plate 17 is sleeved on the outer surface of the pull ring 12 near its top, a stop block 18 is fixedly connected to the bottom of the stop plate 17, and a tension strip 19 is fixedly connected to the side of the stop plate 17 away from the stop block 18. In use, the hook is connected to the pull ring 12. When lifting, the upper ring body 11 and the lower ring body 13 rotate relative to each other to meet the angle change of the lifting ring body 3 during lifting. At the same time, after the lifting ring body 3 is installed, the stop block 18 of the stop plate 17 is inserted into the hexagonal groove at the top of the bolt 14 to prevent the bolt 14 from rotating during lifting, ensuring that the stress is transmitted vertically on the lifting ring body 3, providing a basis for load adjustment. The stop plate 17 can be used as a wrench to install and tighten the eye-shaped rotating lifting ring. When the ring body rotates to the required direction, the direction of the ring body can be fixed by the stop plate 17 to prevent it from rotating arbitrarily during use. This ensures that the lifting ring remains at the appropriate angle during the lifting process, making the lifting operation more stable and safe. The stop plate 17 of the eye-shaped rotating lifting ring is existing technology and will not be explained in detail.

[0022] Working principle: In this embodiment, the eye-shaped rotating lifting ring load adjustment device is used by simultaneously inserting each eye-shaped lifting ring into the slide groove 2 and the frame 5, and putting on the nut 4 to prevent them from falling off. The lifting ring body 3 is fixed to the pull ring 12 of the hook to be connected to the eye-shaped lifting ring. The electric telescopic rod 6 is started to drive the two frames 5 to move closer to each other, which in turn drives the four lifting ring bodies 3 to move closer to each other. By translating the lifting ring body 3 on the lifting plate 1, the lever arm is changed, thereby adjusting the load of each lifting point to achieve the load adjustment effect. The hook is connected to the pull ring 12. When lifting, the upper ring body 11 and the lower ring body 13 rotate relative to each other to meet the angle change of the lifting ring body 3 during lifting. At the same time, after the lifting ring body 3 is installed, the stop block 18 of the stop plate 17 is inserted into the hexagonal groove on the top of the bolt 14 to prevent the bolt 14 from rotating during lifting, ensuring that the stress is transmitted in the vertical direction on the lifting ring body 3, providing a basis for load adjustment.
