The adaptability of the door shaft is its core capability to meet different types of door bodies, installation scenarioses, and functional requirements. It is mainly reflected in four key dimensions: compatibility of installation methods, matching of door body parameters, adaptability to scene functions, and balance between specification standardization and customization. The specific details are as follows:
1、 Installation method: Flexible adaptation to different door structures and space requirements
The installation design of the door shaft needs to be compatible with the assembly logic of different door bodies (such as the presence or absence of door frames and door body shapes), and common adaptation forms include:
Conventional side installation (embedded)
The most mainstream installation method is to divide the door shaft into "frame leaf" (fixed on the side of the door frame/door frame) and "door leaf" (fixed on the side of the door body), which are fastened with screws and suitable for more than 90% of swing doors (such as indoor wooden doors and metal doors for entry), without changing the core structure of the door body, making installation convenient and versatile.
Installation of sky and earth axis (without side structure)
Cancel the traditional side hinges and only install one "shaft core" at the top and bottom of the door body (the top shaft is fixed on the upper edge of the door frame, and the bottom shaft is fixed on the ground/threshold), suitable for doors without door frames (such as glass doors and minimalist metal doors), which not only saves side space but also avoids appearance damage caused by installing hinges on the side of the door body.
Invisible installation (hidden structure)
The door shaft is integrated into the interior of the door body and door frame, with no visible parts on the outside, suitable for "invisible door" scenarioses (such as hidden doors on background walls and study rooms). The core is the design of "built-in shaft sleeve+hidden limit", which ensures the rotation function while achieving an integrated appearance of the door body and wall/cabinet, meeting decorative needs.
Special angle installation (not 90 ° compatible)
Design "angle adjustable shaft sleeve" or "irregular shaft core" for irregular door bodies (such as angled doors, curved doors, folding doors), for example:
The "dual axis linkage door shaft" of the folding door in the bathroom can adapt to the multi angle rotation of the door body during folding;
The "diagonal shaft sleeve" of the angled door frame (such as an octagonal door with a 45 ° joint) ensures that the door body is in contact with the door frame and rotates smoothly.
2、 Door parameters: Accurately match door weight, size, and material
The door axle should be designed with load-bearing and structural strength based on the core physical parameters of the door body (weight, size, material) to avoid jamming, deformation, or detachment due to improper adaptation:
Load bearing grade adaptation
Dividing clear load-bearing intervals based on the weight of the door to form standardized matching:
Lightweight door pivot (load-bearing 5-15kg): suitable for thin indoor doors (such as wardrobe doors, bathroom aluminum buckle doors), mostly made of thin steel plates (1-2mm) or plastic materials, with a compact structure;
Medium sized door shaft (bearing 15-50kg): suitable for conventional entrance doors (wooden doors with a thickness of 40-60mm) and balcony glass doors, made of 3-4mm cold-rolled steel plate stamped and formed, with some reinforced ribs;
Heavy duty door shaft (bearing capacity 50-200kg): Suitable for fire doors, stainless steel doors, and industrial plant doors, using cast steel or solid steel shafts (diameter ≥ 10mm), with reinforced bearings embedded in the shaft sleeve to prevent the shaft core from bending due to long-term load-bearing.
Door size adaptation
Width adaptation: For ultra wide doors (such as double doors and single doors with a width greater than 1.2m), design "extended axle blades" or "multi axis linkage" (such as double doors with 3 hinges evenly distributed for load-bearing) to avoid sagging in the middle of the door due to excessive width;
Thickness adaptation: The height of the door shaft "door leaf" and the spacing between screw holes can be adjusted to adapt to doors of different thicknesses (such as wooden doors with a thickness of 35-50mm and metal doors with a thickness of 50-80mm), without the need for additional drilling or cutting.
Adaptation of door material
Optimize installation structure based on the characteristics of different door materials:
Glass door: The bottom of the door shaft is fixed with "anti slip rubber pad+metal pressing plate" to prevent the glass from breaking due to hard contact; The top shaft core is equipped with a "buffer sleeve" to reduce the impact during rotation;
Solid wood door: The door shaft "door leaf" is designed with "countersunk screws" to prevent screws from penetrating the surface of the wooden door and causing cracking. At the same time, the shaft sleeve is equipped with "soft gaskets" to cushion the impact of wood thermal expansion and contraction on rotation;
Metal door: The door shaft adopts "welding+double fixing with screws" to enhance the connection strength with the metal door body and prevent loosening caused by long-term vibration.
3、 Scenario function: Adapt to environmental requirements and special features
The door shaft needs to be designed according to the environmental conditions (temperature and humidity, corrosiveness) and functional requirements (fire prevention, theft prevention, noise reduction) of the usage scenario
Environmental adaptability and adaptation
Wet/corrosive scenarioses (bathrooms, kitchens, coastal areas): The door shaft material is made of 304/316 stainless steel, and the shaft sleeve is equipped with a "waterproof sealing ring" to prevent water vapor or salt from entering and causing rust. At the same time, the lubricating grease is "water-resistant" (such as lithium based grease) to avoid water loss;
High/low temperature scenarioses (boiler room, cold storage): The door shaft is made of "high temperature resistant cast steel" (fireproof door shaft) or "low temperature resistant engineering plastic" (cold storage door shaft) to ensure structural stability within the range of -30 ℃~800 ℃, without brittle cracking or softening.
Special function adaptation
Fireproof scenario: The door shaft must comply with the GB 12955-2015 "Fire Doors" standard, using "fireproof expansion strips" (expanding and sealing gaps at high temperatures) and "high-temperature resistant bearings" to maintain a load-bearing capacity of more than 1.5 hours at temperatures above 700 ℃, preventing the door from collapsing in the event of a fire;
Anti theft scenario: The anti-theft door shaft is designed with an "anti pry shaft sleeve" (the shaft core is tightly engaged with the shaft sleeve and cannot be removed externally) and a "hidden screw" (screw holes are built in to prevent external damage), which enhances the anti-theft level;
Silent scene: For the door shafts of indoor bedroom and study doors, add a "silent nylon gasket" between the shaft core and the shaft sleeve, or install a "ball bearing" to control the rotational noise below 30dB and avoid affecting rest.
4、 Specification System: Standardized Universal and Customized Supplements
The door shaft achieves wide adaptability through the balance of "standardized basic specifications+customized special requirements":
Standardization of core specifications
The key parameters (such as hole spacing, shaft length, and thickness of hinges) follow industry standards (such as GB/T 3222-2012 "hinges"), for example:
The hole spacing of conventional indoor door hinges is usually 50mm or 75mm, with a shaft length of 10-15mm. They can be directly replaced with old hinges on the market without the need for re drilling;
The diameter of the axis core and the spacing between installation holes of the Tian Di axis are uniformly 12mm, 16mm and other conventional sizes, which are suitable for most threshold and door frame reserved holes.
Customization for special needs
Provide customized services for non-standard scenarioses, such as:
Customize "ultra-low friction copper shafts" for heavy-duty cultural relic display cabinet doors in museums and archives (with built-in lubrication to avoid frequent opening and wear);
Customized "corrosion-resistant 316 stainless steel shaft+explosion-proof limit pin" for explosion-proof doors in chemical plants, suitable for flammable and explosive environments;
Customize a "heavy-duty door shaft with buffering function" for the fire doors of super high-rise buildings to reduce the impact noise when the door is closed.
