The function of the lifting ring is to provide a firm bearing point to ensure the safety and stability of the lifting operation. The lifting ring is usually made of high-strength metal materials and can withstand large tension and loads. It is an indispensable component for lifting and transporting objects and can help move and install large machines, equipment or components.

[0003] Lifting rings are connected to lifting equipment to help lift objects from the ground or other locations. When stacking and loading and unloading heavy objects, lifting rings provide a stable connection point to ensure the safety of heavy objects during handling. Lifting rings are usually made of metal materials and often withstand large tensile forces and impacts. During the lifting process, friction between the lifting ring and the connecting parts of the lifting equipment is likely to occur, which can easily lead to increased wear on the metal surface of the lifting ring screw and affect the working performance of the lifting ring. Therefore, we propose a lifting ring that is convenient for regular lubrication and maintenance. Utility Model Content

A connecting ring 206 is bonded to one side of the cover 205, and a connecting pad 207 is bonded to the inner side of the docking cover 205. The upper side of the connecting ring 206 is in contact with the lower side of the docking cover 205, and the inner side of the docking cover 205 is in contact with the outer side of the connecting pad 207. The outer side of the docking cover 205 is fixed to the knob 208, and one side of the knob 208 is fixed to the connecting ring 1 209. The outer side of the ring 1 is connected to the connecting ring 210, and the connecting ring 1 209 is hung with one end of the hanging chain 211. The end of the hanging chain 211 away from the connecting ring 1 209 is hung with the connecting ring 2 210. The filling port 204 is threadedly connected to the docking cover 205, and the connecting ring 206 and the connecting pad 207 are made of deformable fluororubber.

[0021] In specific implementation, according to Figure 1-Figure 4After the lifting ring is connected to the connecting piece of the lifting equipment, the knob 208 is rotated regularly to make the knob 208 drive the docking cover 205 to rotate, and the docking cover 205 is threadedly connected to the filling port 204, so that the docking cover 205 moves up and is removed from the outside of the filling port 204. At this time, the connected hanging chain 211 can prevent the docking cover 205 from being lost after being removed from the outside of the filling port 204. At this time, the lubricating oil is injected into the filling port 204. At this time, the lubricating oil enters the main flow groove 2 through the filling port 204. At this time, the main flow groove 2 divides the lubricating oil into two streams and enters the secondary flow groove 20 1. The circular diversion of the lubricating oil through the main flow groove 2 can make the lubricating oil smoothly transition to the secondary flow groove 201, reducing the generation of bubbles. At this time, the lubricating oil flows through the secondary flow groove 201 to the diversion groove 202. At this time, the diversion groove 202 can divide the lubricating oil into multiple streams and enter the thread groove of the lifting equipment connector. It can effectively and evenly distribute the lubricating oil and ensure that the lubricating oil covers every contact point of the thread groove of the lifting equipment connector. When the lubricating oil fills the thread groove of the lifting equipment connector, the lubricating oil can overflow from the overflow groove 203. At this time, the lubricating oil liquid can fully fill the screw 101 The threaded surface of the connecting piece of the lifting equipment and the threaded groove of the connecting piece of the lifting equipment can facilitate the staff to determine that the lubricating oil is fully lubricated to the lifting ring, and it is not easy to have lubrication leakage. At this time, the docking cover 205 is rotated and docked with the filling port 204 again, so that the docking cover 205 moves down and is restricted to the outside of the filling port 204. At the same time, the lower side of the docking cover 205 squeezes the connecting ring 206, and the upper side of the filling port 204 squeezes the connecting pad 207. The connecting ring 206 and the connecting pad 207 are made of deformable fluororubber, so that a tight seal is formed between the docking cover 205 and the connecting ring 206. Sealed state, and a sealing state is formed between the connecting gasket 207 and the filling port 204, and the connecting ring 206 and the connecting gasket 207, the connecting ring 206 and the connecting gasket 207 have very good oil resistance, and can maintain stable performance when in contact with lubricating oil, and will not be corroded by the lubricating oil, so that the docking cover 205 and the lifting ring form a double sealing structure, so that the docking cover 205 can improve the anti-leakage ability, and make the lifting ring convenient for evenly and regularly adding lubricating oil for maintenance, so that the lifting ring is not easy to rub against the connecting parts of the lifting equipment, thereby maintaining the working performance of the lifting ring.

[0022] To sum up, after the lifting ring is connected to the connecting piece of the lifting equipment, the knob 208 is rotated regularly to move the docking cover 205 up and remove it from the outside of the filling port 204. At this time, the lubricating oil is injected into the filling port 204. At this time, the lubricating oil enters the main groove 2 through the filling port 204, and the lubricating oil flows to the diversion groove 202 through the secondary groove 201. At this time, the diversion groove 202 can divide the lubricating oil into multiple streams and enter the threaded groove of the lifting equipment connecting piece, which can effectively and evenly distribute the lubricating oil, ensuring that the lubricating oil covers each contact point of the threaded groove of the lifting equipment connecting piece, and is not prone to lubrication leakage. At this time, the docking cover 205 is restricted to the outside of the filling port 204 again to form a double sealing structure, so that the docking cover 205 can improve the anti-leakage ability, making it easy to evenly and regularly add lubricating oil to the lifting ring for maintenance, making it difficult for the lifting ring to rub against the connecting parts of the lifting equipment, and maintaining the working performance of the lifting ring.
