[0013] 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.

[0014] Example like Figure 1-3 As shown in the figure, an embodiment of this utility model discloses a high-strength lifting ring for mining machinery, including a connecting seat 1, a connecting seat 4, and a lifting ring body 7. A fixing screw 2 is provided on one side of the connecting seat 1, and an adjusting component 3 is provided inside the connecting seat 1. A rotating shaft 5 is rotatably connected inside the connecting seat 4, and a rotating block 6 is fixedly installed on the outer wall of the rotating shaft 5. The screw 2 is fixed to the equipment being lifted, and the lifting ring body 7 rotates on the rotating shaft 5 through the rotating block 6, which can automatically adapt to changes in the center of gravity of the heavy object, reducing the risk of the lifting ring body 7 falling off or being structurally damaged. The setting of the adjusting component 3 makes it easy to adjust the length of the lifting ring body 7 according to the actual use, improving the flexibility of use and providing convenience for lifting equipment.

[0015] like Figure 2As shown, in some embodiments, the adjusting component 3 includes two fixed rods 31 fixedly installed inside the connecting seat 1. A sliding plate 32 is slidably connected between the two fixed rods 31. An extension plate 33 is fixedly installed at the end of the sliding plate 32. The extension plate 33 is fixedly connected to the connecting seat 4. First threaded holes 34 are provided on both sides of the extension plate 33. Side plates 35 are fixedly installed on both sides of one end of the connecting seat 1. Second threaded holes are provided on both side plates 35. The sliding plate 32 slides on the fixed rods 31, causing the extension plate 33 to slide out of the connecting seat 1. After adjusting to a suitable position, the position of the extension plate 33 is fixed by the fastening bolts 36, thus completing the length adjustment.
