What Are The Rules For Door Hinges?
The rules of door hinges involve many aspects, including configuration principles, installation specifications, size standards, and use and maintenance.
1. Configuration principles
According to the door panel covering method: select the appropriate hinge according to the way the door panel covers the side panel (full cover, half cover, embedded).
According to the thickness of the door panel: door panels of different thicknesses need to match hinges of corresponding specifications, such as light hinges for thin panels and heavy hinges for thick panels.
According to functional requirements: if damping buffering, quick release functions, etc. are required, specially designed hinges need to be selected.
According to the cabinet structure: special cabinets (such as corner cabinets and bevel cabinets) require customized angle hinges.
According to special door types: each door is equipped with 2 floor door hinges, one on the top and one on the bottom, and no holes are opened in the middle.
2. Installation specifications
Accurate position: the hinge installation position must be consistent with the design drawing, and the fixing screws must be tightened in place.
Smooth contact surface: the contact surface between the hinge and the door panel and frame should be smooth to reduce friction and noise.
Angle adjustment: The opening angle and strength of the hinges need to be adjusted during installation to ensure smooth opening and closing of the door leaf.
Reasonable spacing: Determine the number and spacing of hinges according to the height of the door panel. For example, a heavy door panel with a height of 1.5 meters needs to install 3 hinges.
Hole position matching: The hole positions of hinges of different brands are different, and the holes must be opened strictly according to the brand requirements.
3. Size standard
Hinge cup diameter: Common sizes are 35mm (internationally used) and 40mm (suitable for heavy doors).
Hole depth: Usually 12mm to ensure that the hinge is firmly installed.
Side panel margin: Generally 3-7mm (inclusive), 4.5mm is commonly used.
Installation distance: 37mm for straight and medium bend hinges, and 55mm for large bend hinges.
4. Use and maintenance
Regular lubrication: Add lubricating oil every 2-3 months to keep the pulley smooth and quiet.
Avoid corrosion: Keep dry and avoid contact with condiments such as salt, sugar, and soy sauce.
Prevent impact: Avoid excessive force when opening and closing the cabinet door to prevent the hinge from being hit violently.
Timely tightening: If the hinge is found to be loose or the door panel is uneven, it should be tightened or adjusted immediately with tools.
Cleaning method: Wipe with a dry soft cloth, avoid using chemical cleaners or acidic liquids.
V. Special rules
Two-way hinge: Allows the door or panel to swing in two directions, suitable for scenes that require two-way opening.
Angle selection: Select the appropriate opening angle according to the use requirements, such as 100 degrees, 105 degrees, 180 degrees, etc.
Material matching: The material of the hinge must match the material of the door panel and frame, such as steel frame wooden doors require hinges fixed with welding and wood screws.
Safety specifications: Follow industry standards during installation to ensure that the load-bearing capacity, corrosion resistance and wear resistance of the hinge meet the requirements.
