A door hinge is a device used to connect a door and a door frame, allowing the door to rotate around the hinge axis. It has the following characteristics:
1、 Functional characteristics
1.Implement rotation function
      The main function of a door hinge is to enable the door to open and close smoothly. It fixes one side of the door to the door frame through a core structure, allowing the door to move in a circular motion around the core. For example, on ordinary indoor wooden doors, when people pull the door handle, the door can smoothly rotate and open around the hinge, making it convenient for people to enter and exit the room.
2.Adjustability
      Some door hinges have adjustable functions. You can adjust the up and down, left and right positions of the door, as well as the gap between the door and the door frame. In the process of installing the door, if it is found that the door is not installed horizontally enough or the gap between it and the door frame is uneven, the position of the door can be accurately adjusted by adjusting the screws on the hinge. For example, some high-end aluminum alloy door hinges have specialized adjustment screws that can achieve the desired installation effect of the door after installation.
3.carrying capacity
      The door hinge can withstand the weight of the door. Different types of doors (such as wooden doors, iron doors, glass doors, etc.) have different weights, and the load-bearing capacity of door hinges also varies. For example, the hinges used for heavy-duty warehouse iron doors are generally thick and made of sturdy metal materials, capable of withstanding hundreds of kilograms of weight, ensuring that the door will not sag or be damaged during frequent opening and closing processes.
4.Buffer function (partially equipped with hinges)
      Some high-end door hinges come with buffering devices. When the door is closed, the buffer device can slow down the closing speed of the door, avoid violent collisions between the door and the door frame, thereby reducing noise and extending the service life of the door and door frame. For example, in some high-end hotel room doors or home interior doors, door hinges with hydraulic buffering function are used. When the door is about to close, it will slowly approach the door frame and gently close without producing a "bang" closing sound.
2、 Structural characteristics
1.Composed of multiple components
      It generally includes a hinge cup (installed on the door), a hinge seat (installed on the door frame), and a shaft core. The hinge cup and hinge seat are usually fixed on the door and door frame through screws and other connecting parts, and the shaft core is the key component that connects the hinge cup and hinge seat, allowing them to rotate relative to each other. Some door hinges are also equipped with decorative covers and other components to cover installation marks such as screws, making the appearance of the door more beautiful.
2.Multiple shapes and sizes
     The shapes and sizes of door hinges are diverse. From a shape perspective, there are ordinary flat hinges, which have a relatively simple appearance and are suitable for most ordinary doors; There is also a pipe hinge, which is shaped like a pipe and is generally used for heavier doors or specially designed doors. In terms of size, there are short hinges suitable for small cabinet doors and long hinges for large doors. For example, in wardrobe doors, hinges with shorter length and narrower width are usually used, while in courtyard doors, hinges with longer length and thicker thickness are needed to ensure the stability of the door.
3、 Material characteristics
1.Mainly made of metal material
      Common door hinges are often made of metal materials such as stainless steel, iron, zinc alloys, etc. Stainless steel door hinges have good corrosion resistance and are suitable for doors in humid environments such as kitchens and bathrooms. Iron hinges have high strength, but are prone to rusting, so surface treatments such as galvanizing and painting are generally carried out. Zinc alloy hinges have exquisite appearance and good casting performance, and can be made into complex shapes. They are commonly used in doors with high decorative requirements.
2.Partially made of plastic material (auxiliary components)
      In some door hinges, there may be a small amount of plastic components. For example, some gaskets or moving parts in the buffer device may be made of plastic. Plastic components can reduce friction, provide cushioning and shock absorption, and have relatively low costs.
