Introduction: There are numerous accessories available for doors and windows, and among these, hinges play a crucial role. Let’s delve deeper into this topic today.
Hinges, commonly referred to as door or furniture hinges, are typically designed as two-part structures. These are metal pieces that connect different sections of furniture and allow movement. Hinges are essentially devices that enable connections and rotations, allowing doors, covers, or other swinging elements to pivot. They are usually made up of two metal blades linked together by a pin.
1. Types of Hinges:
Ordinary Hinge: Widely used for cabinet doors, windows, and doors. Made from materials like iron, copper, and stainless steel. The downside of ordinary hinges is that they lack the spring hinge's functionality. After installation, additional beads are required to prevent the door panel from being blown open by the wind.
Pipe Hinge: Also known as a spring hinge, it is primarily used to connect furniture door panels, requiring a panel thickness of approximately 16 to 20 mm. Made from materials like galvanized iron and zinc alloy. Spring hinges come with adjustment screws that can control the height and thickness of the panels both vertically and horizontally. One notable feature is its ability to adjust the opening angle of cabinet doors based on space. Beyond the standard 90-degree angle, options like 127 degrees, 144 degrees, and 165 degrees are available, ensuring a variety of cabinet door extensions.
Door Hinge: Divided into regular and bearing types. Bearing hinges can be further categorized into copper and stainless steel varieties. Copper bearing hinges are more popular due to their attractive appearance, bright finish, reasonable pricing, and the inclusion of screws.
Bearing Hinges (Copper): Each hinge contains a one-way thrust ball bearing in the shaft, making the door switch smooth and effortless. They are typically used on heavy-duty doors or specialized steel-framed steel doors. Inclined Surface Removal Hinge: Utilizes the beveled surface of the hinge and the weight of the door leaf to automatically close the door. Ideal for lighter wooden doors or toilet half-section doors.
Cold Storage Door Hinge: Surface-painted, with large sizes made of steel plate and smaller sizes made of cast iron. Commonly used on cold storage doors or heavier insulated doors.
Fan Hinge: The stacking thickness of the two sheets in a fan-shaped hinge is about half that of a regular hinge, making it suitable for various doors and windows requiring rotation and opening/closing.
Silent Hinge: Also known as nylon washer hinges, these hinges operate quietly when opening and closing doors and windows. They are primarily 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 mostly used on double-layer windows.
Flip Window Hinge: During installation, the two pages with mandrels are mounted on both sides of the window frame, while the two pages without mandrels are installed on both sides of the window sash. One slotless spindle negative plate must be installed on the side of the slotted sash for loading and unloading of the window sash. They are used on movable windows for factories, warehouses, residential buildings, public buildings, etc.
Multi-function Hinge: When the opening angle is less than 75°, it has an automatic shut-off function. At angles between 75° and 90°, it remains stable, and if greater than 95°, it will automatically lock. This hinge can replace a regular hinge on doors.
Anti-theft Hinge: Unlike ordinary hinges, where the door leaf can be removed once the shaft is pulled out, anti-theft hinges prevent removal by locking the pins and pinholes on the two hinge sheets. This effectively prevents the door leaf from being removed and provides theft protection. It is suitable for residential doors.
Spring Hinge: Automatically closes the door leaf after opening. Single-spring hinges can only be opened in one direction, whereas double-spring hinges can be opened in both inward and outward directions. They are mainly used on public building gates.
Double-Axis Hinge: Allows free opening, closing, and removal of the door leaf. 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. Composed of a movable assembly or foldable material, hinges hold an important place in furniture hardware accessories. The quality of hinges directly affects the usability of furniture and doors.
Classifications:
1. Based on base type: Dismountable and Fixed;
2. Based on arm body type: Slide-in and Card Type;
3. Based on door panel coverage: Full Cover (Straight Bend, Straight Arm), Half Cover (Middle Bend, Curved Arm), Inner (Big Bend, Big Bend);
4. Based on hinge development stages: One-stage Force Hinge, Two-stage Force Hinge, Hydraulic Cushion Hinge, Touch Self-Opening Hinge, etc.;
5. Based on door opening angle: Standard angles are 95-110 degrees, with special angles at 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, and 180 degrees;
6. Based on hinge type: 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.
By Usage Occasion:
1. General Hinges: Commonly referred to as regular hinges, used for cabinet doors, windows, and doors. Materials include iron, copper, and stainless steel. The downside is the absence of spring hinge functionality, necessitating the use of additional beads to secure the door panel. Special hinges include stripping hinges, flag hinges, and H hinges, which can be disassembled and installed according to specific needs.
2. Spring Hinges: Primarily used for cabinet and wardrobe doors, requiring a panel thickness of 18-20mm. Material-wise, they can be galvanized iron or zinc alloy. Functionally, they can be hole-free (bridge hinges) or drilled. Bridge hinges are versatile, not restricted by door styles, while drilled hinges are standard for cabinet doors, ensuring wind-resistant closure without needing additional beads.
3. Door Hinges: Divided into ordinary and bearing types, with copper and stainless steel varieties. Copper hinges are popular due to their aesthetic appeal, durability, and cost-effectiveness.
4. Mechanical and Electromechanical Cabinet Hinges: High-wear nylon hinges, corrosion-resistant zinc alloy hinges, and stainless steel hinges resistant to oxidation and corrosion are used in electromechanical cabinets and machinery.
5. Heavy-Duty Hinges: Designed for special positions, requiring robust construction with sizes over 150mm and high load-bearing capacity. Often found in refrigerator and freezer doors, typically made of zinc alloy.
6. Specialty Hinges: Corner hinges with wide opening angles are commonly used.
7. Other hinges include countertop, door, and glass hinges. Glass hinges are used for frameless glass cabinet doors with a glass thickness requirement of up to 5-6mm, featuring all spring hinge properties but without magnetic suction or top-mount designs.
In conclusion, hinges come in diverse types, each serving specific purposes and meeting varying functional demands across different applications.
Exit Sign For Aluminum And Acrylic
The LED exit sign light is specially made from aluminum and acrylic materials, and is also fast dissipating heat, insulating and corrosion resistant.
