Description

Technical Field

[0001] The utility model relates to the technical field of top and bottom hinges, in particular to an adjustable top and bottom hinge. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow rotation between them. Traditional hinges used to connect cabinet bodies and doors have the following issues: After assembly, the door and window sashes and frames may experience inconsistent clearances. Failure to adjust this clearance can affect the aesthetics of the door and window, and in severe cases, affect its opening and closing.

[0003] Conventional hinges are mostly fixed to door and window frames or door and window sashes by bolts. However, it is not convenient to fix the hinges with screws for doors and windows of special sizes. In addition, the sizes of conventional hinges are mostly fixed and not easy to adjust according to the installation environment. Therefore, their adaptability is relatively general.
