Detailed introduction to the types of doors and windows hinges

Introduction: There are numerous accessories available for doors and windows, among which hinges play a significant role. Let’s dive deeper into the world of hinges today. Hinges, commonly referred to as door or furniture hinges, are typically designed in a two-part form, acting as a metal component that connects two parts of furniture and allows them to move relative to each other. A hinge is essentially a device that facilitates the connection and rotation of objects, enabling doors, covers, or other swinging components to rotate. It usually consists of a pair of metal plates connected by a pin. 1. What are the different types of hinges? Hinge Types: Ordinary Hinge: Commonly used for cabinet doors, windows, and doors. Made from materials such as iron, copper, and stainless steel. The downside of ordinary hinges is that they lack the functionality of spring hinges. After installation, stoppers or beads need to be added to prevent the door panel from being blown open by the wind. Pipe Hinge: Also known as spring hinges, these are primarily used for connecting furniture door panels. They generally require a panel thickness of 16-20 mm. Made from materials like galvanized iron and zinc alloy, they come equipped with adjustment screws allowing for vertical and horizontal adjustments of the panels. One of their standout features is the ability to adjust the opening angle of cabinet doors based on available space. Besides the standard 90-degree angle, options like 127 degrees, 144 degrees, and 165 degrees are also available, offering versatile extensions for various cabinet doors. Door Hinge: Divided into ordinary and bearing types, as previously discussed. Bearing types can further be categorized by material into copper and stainless steel. Based on current consumer trends, copper bearing hinges are more popular due to their attractive style, brightness, reasonable pricing, and screw attachments. Bearing Hinges (Copper): Each hinge contains a one-way thrust ball bearing in the shaft, making door operation smooth and effortless. These are predominantly used for heavy-duty doors or special steel-framed steel doors. Inclined Surface Removal Hinge: This hinge uses the beveled surface of the hinge and the weight of the door to automatically close it. It's ideal for lighter wooden doors or toilet half-section doors. Cold Storage Door Hinge: These hinges are surface baked and come in large sizes made of steel plate or smaller sizes made of cast iron. They are used on cold storage doors or heavier insulated doors. Fan Hinge: With a stacking thickness of about half that of regular hinges, fan-shaped hinges are suitable for various doors and windows requiring rotation and opening/closing. Silent Hinge: Also known as nylon washer hinges, these hinges ensure quiet operation when opening and closing doors and windows. They are commonly used in public building doors and windows. Single Flag Hinge: Made of stainless steel, these hinges are rust-resistant, wear-resistant, and easy to disassemble. They are predominantly used on double-layer windows. Flip Window Hinge: During installation, the two hinge plates with spindles should be installed on both sides of the window frame, while the two hinge plates without spindles should be installed on both sides of the window sash. One of the slotless spindle hinge plates must be installed on the side of the slotted sash for window sash loading and unloading. These are used on factory, warehouse, residential, and public building movable windows. Multi-function Hinge: When the opening angle is less than 75 degrees, it has an automatic shut-off function. Between 75 and 90 degrees, it remains stable on its own, and above 95 degrees, it will automatically lock in place. This hinge can replace a regular hinge on doors. Anti-Theft Hinge: Unlike ordinary hinges, where pulling out the pin allows the door leaf to be removed, anti-theft hinges prevent this through the self-locking mechanism of the pins and pinholes on the two hinge plates, ensuring the door cannot be removed and providing theft protection. These are suitable for residential doors. Spring Hinge: These hinges automatically close the door after it is opened. Single-spring hinges can only be opened in one direction, while double-spring hinges can be opened in both inward and outward directions. They are primarily used on public building gates. Double-Axis Hinge: These hinges allow free opening, closing, and removal of the door leaf. They are suitable for general doors and windows. 2. Introduction to Door Hinges A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. It may consist of a movable assembly or a foldable material. Hinges hold a crucial position in furniture hardware accessories, and the quality of the hinges directly affects the usability of furniture and doors. Based on the base type, hinges can be classified as either removable or fixed. According to the type of arm body, they can be divided into slide-in and card types. Depending on the door panel coverage, they are classified as full cover (straight bend, straight arm), half cover (middle bend, curved arm), and inner (big bend, big bend) where door panels are hidden inside. By the styles of hinge development stages, they are categorized into: one-stage force hinge, two-stage force hinge, hydraulic cushion hinge, touch self-opening hinge, etc. According to the door opening angle, hinges are generally between 95-110 degrees, with special ones ranging from 25, 30, 45, 135, 165, to 180 degrees. Based on the type of hinges, they include: ordinary first and second-stage force hinges, short arm hinges, 26 cup mini hinges, bullet hinges, aluminum frame door hinges, special angle hinges, glass hinges, rebound hinges, American hinges, damping hinges, thick door hinges, etc. Classified by usage occasion: 1. General Hinges: Often referred to as standard hinges, these can be used for cabinet doors, windows, and doors. Hinges can be made of iron, copper, or stainless steel. The downside of ordinary hinges is the absence of spring hinge functionality. After installation, stoppers or beads must be installed to prevent the door panel from being blown open by the wind. 2. Spring Hinges: Primarily used for cabinet doors and wardrobe doors, requiring a board thickness of 18-20mm. Material-wise, they can be galvanized iron or zinc alloy. Functionally, they can be divided into hole-making and non-hole-making types. Non-hole-making ones are known as bridge hinges, resembling a bridge, and are not restricted by door styles. Hole-making ones are commonly used on cabinet doors, with features like hole requirements, limited door styles, and no need for additional stoppers post-closure. 3. Door Hinges: Divided into ordinary and bearing types, bearing types can be copper or stainless steel. Copper bearing hinges are more popular due to their aesthetics, brightness, reasonable pricing, and screw attachments. 4. Mechanical and electromechanical cabinet hinges include nylon hinges with high wear resistance, corrosion-resistant zinc alloy hinges, and corrosion-resistant, oxidation-resistant stainless steel hinges. These are often used in electromechanical cabinet doors and mechanical equipment operating boxes. 5. Heavy Duty Hinges: Due to their unique installation positions, hinges require high standards. Sizes are typically above 150mm, with high load-bearing capacity, and shapes/structures meeting the special requirements of cabinet doors. They are frequently used in refrigerator and freezer doors and are mostly made of zinc alloy. 6. Special Hinges: Also known as corner hinges, they have a large opening angle and are widely used in daily life. 7. Other hinges include countertop hinges, door hinges, and glass hinges. Glass hinges are used to install frameless glass cabinet doors, with a glass thickness requirement of no more than 5-6mm. Styles include hole options and all the properties of spring hinges, but magnetic suction types and upper/lower top-mount types are not made, such as Pepsi and magnetic glass hinges. In conclusion, hinges are indispensable in the design and functionality of doors and windows, offering a wide range of options tailored to specific needs and applications.
