Introduction to Hinges:

A hinge is a metal or non-metal component that connects two parts of furniture, consisting of two leaves connected by a pin, primarily serving the purpose of connecting and allowing relative rotation between the two parts. It is widely used in the opening and closing of doors and windows, and can be classified into various types such as ordinary hinges, pipe hinges, and gate hinges based on their characteristics and uses.

Introduction to Joints:

A joint, typically using a four-bar or six-bar structure, bears external forces such as vertical gravity and wind. In modern homes, hydraulic joints are particularly common, as their buffering function can effectively reduce collision noise when doors and windows close. Joints can be divided into visible joints and concealed joints, with the former mostly used for doors and the latter commonly found on furniture.

Difference Between Hinges and Joints:

Although both hinges and joints are used for connection and rotation, they differ in structure and usage. Hinges primarily connect fixed parts and movable parts, such as the connection between a door and a wall; while joints are more flexible, used for connections between fixed and movable objects as well as between movable objects.

Differences in Appearance and Function:

Hinges typically have a pivot structure and are made of materials such as iron, copper, and stainless steel; while joints are rod-based structures that can achieve both linear and rotational movement. Functionally, hinges are mainly used for the rotation of doors and windows, while joints have more application scenarios, such as the installation of cabinet and wardrobe doors.

Differences in Installation Location and Usage Method:

Hinges are mostly used for the installation of doors and windows, while joints are more commonly found on furniture such as cabinets and wardrobes. Additionally, hinges need to be paired with supports to avoid damage from wind, while joints can be used independently due to their built-in damping.

Usage Precautions:

When choosing to use hinges or joints, it is necessary to consider the specific situation. For example, casement windows typically use hinges, while oversized casement windows may require multiple joints to share the load. Furthermore, attention should be paid to the materials, sizes, and other parameters of hinges and joints to ensure they are suitable for specific installation environments and usage needs.
