[0002] A hinge is a hinged device that connects two objects. It typically consists of two metal or plastic pieces connected by a hinge or axle, allowing the connected objects to open and close like a book. The main function of a hinge is to connect and support, firmly linking two objects (such as doors, windows, lids, boxes, etc.) together while allowing them to rotate freely and open and close.
[0003] Existing hinges, such as the one disclosed in CN222162301U, involve a hinge including a first hinge piece, a second hinge piece, and a core. The first hinge piece has at least two spaced-apart first sleeves on one side, and the second hinge piece has a second sleeve on one side corresponding to two adjacent first sleeves. The core is inserted into and fixedly connected to the second sleeve. The upper end of the core is inserted into the first sleeve at the upper end of the first hinge piece, and the lower end of the core is inserted into the first sleeve at the lower end of the first hinge piece. The core and the first sleeves are rotatably engaged. The hinge also includes an upper support seat and a lower support seat. The upper support seat is disposed in and fixedly connected to the first sleeve at the upper end of the first hinge piece, and the lower support seat is disposed in and fixedly connected to the first sleeve at the lower end of the first hinge piece. By adopting the above technical solution, this utility model provides a hinge with a boss on the shaft core and a support seat added inside the first sleeve.
