[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. In daily life, hinges are widely used. For example, in the field of furniture, cabinet doors, wardrobe doors, etc. usually rely on hinges to open and close. High-quality hinges can ensure that the doors open and close smoothly and quietly, and have a long service life. Common stainless steel hinges are rust-proof, strong and durable. In industrial production, hinges also play an important role. The hatches of large equipment and the protective covers of machines are inseparable from the connection of hinges. In addition, different types of hinges are suitable for different scenarios and needs. From the perspective of materials, in addition to stainless steel, there are also many options such as iron and copper. Iron hinges are low in cost, but easy to rust; copper hinges are beautiful and durable, but the price is relatively high. Although hinges seem inconspicuous, they are an indispensable and important part in connection and rotation.

[0003] Long-term and frequent use may cause wear of the hinge's moving parts, thus affecting its rotation flexibility and stability. For example, some old cabinet door hinges will get stuck or shake when opening and closing the cabinet doors after being used for a long time. At this time, lubricating oil needs to be dripped on the hinge for lubrication. However, such lubrication method not only has a short duration, but also the contact between the oil and the moving parts is not uniform, which is not conducive to reducing hinge wear.
