Description

Technical Field

[0001] The present invention relates to the technical field of hardware accessories, and in particular to a top and bottom hinge with an adjustable opening and closing force. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. A hinge can be made of a movable component or a foldable material.

[0003] Wardrobes, cabinets, and other cabinets currently on the market feature doors that can be opened. Traditional hinges connecting the cabinet body and doors have the following issues: Because they lack or cannot provide sufficient closing force, the door can cause play or rebound after closing. Alternatively, due to excessive closing force, the door closes too quickly, causing the door to hit the cabinet body and make noise. This can even damage the cabinet over time. This same issue also exists on various doors, including conference room doors and bedroom doors.
