Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and particularly relates to a hinge for a refrigerator drawer. Background Art

[0002] A hinge, also known as a hinge joint, is a mechanical device that connects two solids and allows relative rotation between them. It is widely used in doors, windows, furniture, etc., enabling door panels or lids to open and close relative to a fixed frame. There are various types of hinges, including ordinary hinges, spring hinges, concealed hinges, etc. Different types of hinges are suitable for different installation requirements and scenarios. In the use of refrigerators, the front and back sliding of the refrigerator drawer is mostly achieved through slide rails. However, most refrigerator drawers do not have a hinge structure during use, resulting in limited movement of the refrigerator drawer. After people pull the refrigerator drawer outwards, they cannot rotate and adjust it, and can only completely disassemble it for use. There is a lack of corresponding rotating structure and limiting structure. In actual life, people face various situations. For example, when local cleaning is required, the inability to rotate may make it inconvenient to pour out the dirt inside, resulting in inconvenient cleaning.

[0003] In summary, there are some problems in the use of refrigerator drawers without hinges, so it is hoped to propose a new structure to solve the above technical problems. Summary of the Utility Model
