A hinge is a mechanical part used to connect two objects and allow them to move relative to each other. Depending on their structure, function and use, hinges can be divided into many types. Here are some common types of hinges:
First, classification by structure
1. Single Axis hinge: This is the most common type of hinge that allows an object to rotate along a fixed axis. Such hinges are commonly used in applications such as doors, drawers and cabinets.
2. Two-axis hinge: allows two objects to rotate on two planes respectively. For example, it can be used to connect two flat mirrors so that they can rotate relative to each other.
3. Multi-axis hinges: such as four-axis hinges, which allow objects to rotate in multiple directions, are often used in more complex mechanical systems.
Second, classification by function
1. Ordinary hinges: used to connect doors, Windows, cabinets and other furniture, allowing them to rotate along a fixed axis. Such hinges usually have no additional features such as cushioning or self-locking.
2. Buffer hinge: Also known as hydraulic buffer hinge or damping hinge, it has a buffer function to reduce noise and collision when the door or drawer is closed. This hinge is usually used in places that require a quiet environment, such as libraries, hospitals, etc.
3. Self-closing hinge: with automatic closing function, when the door or drawer is opened to a certain Angle, the hinge will automatically close it. This kind of hinge is usually used in places that need energy saving or safety, such as offices, schools, etc.
4. Folding hinges: Allow doors or drawers to fold at a smaller Angle for easy storage and transportation. This kind of hinge is usually used in folding doors, folding tables and other furniture.
Third, classification by use
1. Furniture hinges: used to connect the door panel and cabinet of furniture, such as cabinet door hinges, wardrobe door hinges, etc.
2. Door and window hinges: used to connect doors and Windows and door frames, allowing doors and Windows to open and close freely.
3. Industrial hinges: Used to connect components on industrial equipment or machines, which usually need to withstand greater weight and pressure.
Fourth, according to the installation classification
1. Hidden hinge: Designed so that the hinge does not reveal the outside when closed, providing a clean appearance. They are commonly used in cabinet doors, drawers, etc. where hinges need to be hidden.
2. Open-mounted hinge: The hinge part is still visible when closed, usually used for doors, Windows and other occasions where visible hinges are needed.
Fifth, other special hinges
1. Spring hinge: with spring inside, it can automatically spring back into place after the door or drawer is closed. They are usually used in situations where an automatic shutdown function is required.
2. Gravity hinges: rely on their own weight to close the door or drawer, no additional springs or hydraulic devices are required.
3. Spherical hinge: The use of spherical bearings to provide smooth movement and low friction is usually used in equipment requiring high durability and smooth movement.
To sum up, there are many kinds of hinges, and each type has its specific structure and function. When selecting hinges, you need to select them based on actual requirements and application scenarios.
