(I) Dimensions
The common size of adjustable hidden door hinges is 200*32mm. This specific size is the result of careful design and optimization, and it can be well adapted to most doors of different thicknesses and widths on the market. Whether it is a relatively thin home interior door or a relatively heavy commercial door, a hinge of this size can provide stable and reliable connection and support. In practical applications, it can ensure that the door remains stable during opening and closing, without shaking or deflection, providing users with a good user experience.
(II) Material properties
Zinc alloy material: Zinc alloy has many excellent properties. It has high strength and hardness, which enables the hinge to withstand the weight of the door and the stress caused by frequent opening and closing actions. During long-term use, zinc alloy hinges are not easy to deform and can always maintain their original shape and function. In addition, zinc alloy also has good casting properties, which can produce hinge parts with complex shapes and high precision to meet different design requirements.
Aluminum alloy material: Aluminum alloy is favored for its light weight and corrosion resistance. The light weight makes the hinge more convenient during installation and use, reducing the overall burden of the door. At the same time, a dense oxide film can be formed on the surface of the aluminum alloy, which effectively prevents the corrosion of the hinge by corrosive substances such as oxygen and moisture in the air, thereby extending the service life of the hinge. In some humid or highly corrosive environments, the advantages of aluminum alloy hinges are more obvious.
(III) Opening range
The opening range of the adjustable hidden door hinge can reach 180°. This feature has extremely high practical value. In places with limited space, such as small rooms and narrow corridors, the 180° opening range allows the door to be fully opened, providing sufficient space for people to enter and exit and carry goods, avoiding the inconvenience caused by insufficient door opening angle. In addition, in some special occasions where a large angle of opening is required, such as conference rooms and exhibition halls, the hinge can also meet the needs, allowing the door to be fully opened to facilitate people's activities and communication.
(IV) Adjustment function
Up and down adjustment: +3.0mm up and down adjustment can be achieved. During the installation of the door, the height of the door may deviate due to factors such as uneven ground and door frame installation errors. The up and down adjustment function of the adjustable hidden door hinge can accurately adjust the height of the door to perfectly match the surrounding environment. For example, when installing a wooden door, if there is a certain height difference between the ground, by adjusting the hinge, the gap between the door and the ground can be made uniform, ensuring the sealing and aesthetics of the door.
Left and right adjustment: The left and right adjustment range is +2.0mm. During the installation and use of the door, the door leaf may deviate left and right. This may be caused by reasons such as non-vertical installation of the door frame and manufacturing errors of the door itself. The left and right adjustment function of the adjustable hidden door hinge can easily solve this problem. By fine-tuning the hinge, the door leaf is restored to the correct position, ensuring smooth opening and closing of the door, and avoiding friction or collision between the door leaf and the door frame.
Front and rear adjustment: The front and rear adjustment can reach +1.0mm. This adjustment function is mainly used to adjust the front and rear position relationship between the door leaf and the door frame. In some occasions where the installation accuracy of doors is required to be high, such as high-end hotels and luxury residences, the front and rear adjustment function can ensure that the gap between the door leaf and the door frame is uniform and consistent, improving the overall quality and aesthetics of the door. At the same time, it can also compensate for the slight deformation of the door caused by uneven force during use, and maintain the good performance of the door.
(V) Installation convenience
The installation process of the adjustable hidden door hinge is relatively simple, and does not require complex tools and professional skills. Its design fully considers the convenience of installation, and usually adopts a modular design, and the connection and assembly between the various components are very convenient. During installation, just follow the steps in the instructions and use common tools such as screwdrivers to accurately fix the hinges on the door and door frame. Compared with traditional door hinges, adjustable hidden door hinges greatly save installation time and labor costs, and improve installation efficiency.
Home door application: In modern home decoration, adjustable hidden door hinges are widely used in various indoor doors, such as bedroom doors, kitchen doors, bathroom doors, etc. For bedroom doors, the hidden design makes the door more coordinated with the overall bedroom decoration style, creating a warm and comfortable sleeping environment. At the same time, the adjustability can fine-tune the position of the door according to personal usage habits and the actual layout of the room, ensuring that the opening and closing of the door does not affect the placement of furniture and the use of other spaces.
Office door application: Adjustable hidden door hinges have been widely used in office doors in commercial places such as shopping malls, hotels, and office buildings. The office doors in these places usually need to be opened and closed frequently, and the durability and flexibility of the hinges are required to be high.

At the same time, the 180° opening range facilitates personnel entry and exit and improves office efficiency. Its adjustable function can ensure the installation consistency of a large number of office doors, making the entire office area look more neat and beautiful.
School door application: In school teaching buildings, libraries, dormitories and other places, adjustable hidden door hinges are widely used on various doors. School doors are used very frequently and need to have good durability and stability. The zinc alloy or aluminum alloy material of the adjustable hidden door hinge can meet this requirement and ensure that the door will not malfunction during long-term use. At the same time, its adjustment function can adjust the position of the door according to the actual installation of the school door to ensure smooth opening and closing of the door, which is convenient for daily use by teachers and students.
Ship door application: On ships, due to limited space and special environment, the requirements for doors are high. The compact design and hidden characteristics of the adjustable hidden door hinge make it very suitable for the use of ship doors. Its material has good corrosion resistance and can resist the erosion of seawater. The adjustable function can adjust the position of the door according to the actual installation of the ship door to ensure that the door can still open and close normally when the ship is shaking. The 180° opening range facilitates the passage of personnel inside the ship and the handling of equipment.
(I) Regular cleaning
Daily cleaning: Regularly wiping the hinge surface with a clean soft cloth is an important step in maintaining adjustable hidden door hinges. In daily use, door hinges will accumulate dust, dirt and other impurities, which will not only affect the aesthetics of the hinge, but may also enter the hinge and affect its normal operation. Therefore, wipe the hinge surface with a clean soft cloth at least once a week to remove dust and dirt on the surface. When wiping, pay attention to moderate force to avoid scratching the hinge surface.
Deep cleaning: The hinge needs to be deeply cleaned every once in a while. You can use a mild detergent, such as neutral soapy water, soak a soft cloth and wipe the hinge surface. But be careful to avoid using detergents containing corrosive ingredients, such as strong acids and alkalis, so as not to damage the protective layer on the hinge surface. For some difficult-to-clean gaps, you can use a small brush to clean them to ensure that all parts of the hinge are thoroughly cleaned.
(II) Lubrication and maintenance
Lubricant selection: Every once in a while, you need to drip an appropriate amount of lubricant into the moving parts of the hinge to reduce friction and maintain the flexibility and smoothness of the hinge. When choosing lubricants, you should choose special lubricants suitable for door hinges, such as engine oil or butter. These lubricants have good lubrication performance and stability and can provide long-term protection for hinges.
Lubrication method: When dripping lubricants, the moving parts of the hinges should be fully exposed to ensure that the lubricants can be evenly applied to each friction surface. Generally speaking, lubrication and maintenance are performed once a quarter. However, if the door is used frequently or the environment is harsh, such as dampness and dust, the frequency of lubrication and maintenance can be appropriately increased. After dripping lubricants, move the door several times so that the lubricants can fully penetrate into the hinge and play a lubricating role.
(III) Check and tighten
Regular inspection: Regularly checking whether the fastening screws of the hinges are loose is a very important maintenance measure. Loose screws may cause the hinge position to shift, affecting the normal use of the door. It is recommended to check the fastening screws of the hinges once a month and tighten them with a suitable screwdriver. When tightening the screws, pay attention to moderate force to avoid damaging the screws or hinges with excessive force.
Special situation inspection: If the door is hit by a large external force, or if the door is found to be shaking, deflecting or other abnormal conditions during use, the fastening screws of the hinges should be checked in time. Because these conditions may cause the screws to loosen and affect the stability of the hinges. When checking, carefully check the tightness of each screw to ensure that all screws are in a tight state.
(IV) Avoid external force impact
Daily use precautions: In daily use, avoid excessive external force impact on the door. For example, do not push or pull the door hard, do not hang heavy objects on the door, etc. Excessive external force impact may cause hinge damage and affect the normal use of the door. If the door is hit, check whether the hinge is damaged in time, and replace it in time if damaged.
Special environment protection: In some special environments, such as areas with strong winds and places with frequent personnel flow, appropriate protective measures should be taken to prevent the door from being hit by external forces. A buffer device can be installed on the door to reduce the impact force of the door during opening and closing. At the same time, it is necessary to strengthen the daily management and maintenance of the door, and timely discover and deal with potential safety hazards.
(V) Environmental adaptation
Maintenance in humid environment: In a humid environment, adjustable hidden door hinges are more susceptible to corrosion. Therefore, more attention should be paid to the maintenance of the hinges. Anti-rust oil can be applied regularly to enhance the corrosion resistance of the hinges. Anti-rust oil can form a protective film on the surface of the hinge to prevent moisture and oxygen erosion. At the same time, the environment should be kept ventilated and dry to reduce the impact of moisture on the hinges. Dehumidifiers, ventilation equipment, etc. can be used to reduce the humidity of the environment.
Corrosive environment maintenance: In some highly corrosive environments, such as chemical plants and seaside, the maintenance of adjustable hidden door hinges is particularly important. In addition to applying anti-rust oil regularly, a corrosion-resistant coating, such as galvanizing, chrome plating, etc., can also be applied to the surface of the hinge to further improve the corrosion resistance of the hinge. At the same time, the corrosion of the hinge should be checked regularly. If there are signs of corrosion, they should be dealt with in time to avoid further expansion of corrosion.
