Description

Technical Field

[0002] In architecture, a window refers to an opening built in a wall or roof to allow light or air to enter a room. As early as the Sui Dynasty in China, the Guanwen Hall in the Ziwei City of the Luoyang Imperial Palace had windows that could open and close automatically.

[0003] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. Hinges are mostly installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to the material. In order to give people a better experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is that they provide a buffering function when the cabinet door is closed, which minimizes the noise caused by the collision between the cabinet door and the cabinet body when it is closed.

[0004] In the prior art, the hinges for opening and closing doors and windows cannot limit the opening and closing degree of the windows when they are in the open and closed state, and it is troublesome to disassemble and inspect the window joints. Utility Model Content
