Introduction
Cylindrical hinges, also known as barrel hinges, are commonly used in doors, windows, and cabinets. They allow the door or window to swing open and closed while remaining attached to the frame. Cylindrical hinges are made up of several parts that work together to provide smooth and reliable movement. This article will discuss the working principle and structure of cylindrical hinges.
Working Principle
1. Cylindrical hinges work by using a pin that connects the two halves of the hinge together. This pin allows the hinge to rotate, which in turn allows the door or window to swing open and closed.
2. The pin is held in place by a set of bearings or bushings. These bearings reduce friction and wear on the hinge, allowing it to move smoothly and easily.
3. The hinge is attached to the door or window frame using screws. These screws hold the hinge in place and allow it to pivot around the pin.
Structure
4. Cylindrical hinges are typically made of metal, such as brass or stainless steel. This makes them strong and durable, able to withstand the weight of heavy doors and windows.
5. The two halves of the hinge are shaped like cylinders, hence the name cylindrical hinge. They are connected by a pin that runs through the center of the cylinders.
6. The bearings or bushings that hold the pin in place are located at the top and bottom of the cylinders. They are usually made of brass or nylon, and are designed to reduce friction and wear on the hinge.
7. The screws that attach the hinge to the door or window frame are located on the side of the cylinders. They are usually countersunk, which means they are designed to sit flush with the surface of the hinge, creating a smooth and seamless appearance.
