Spring hinge and its installation precautions_Hinge knowledge_Tallsen

Spring hinges are commonly used in various types of doors, including hollow doors, cabinet doors, and wardrobe doors. These hinges are typically constructed from galvanized iron and zinc alloy, offering durability and strength. One of the key features of spring hinges is their two-way opening mechanism, allowing the door to swing in both directions.

Additionally, spring hinges are equipped with adjusting screws, which play a vital role in fine-tuning the height and thickness of the hinge plate. This adjustability is crucial in ensuring a proper fit and smooth operation of the door. The distance between the two screw fixing holes on the side of the hinge is usually standardized at 32mm, while the distance between the hinge's diameter side and the two sides of the plate is 4mm.

Apart from these general specifications, spring hinges also come in special variations, such as inner 45-degree hinges, outer 135-degree hinges, and open 175-degree hinges. These specialized hinges cater to specific requirements and enhance the flexibility and functionality of the doors they are installed on.

During the installation of spring hinges, it is important to pay attention to several crucial points. Firstly, it is essential to check if the hinge matches the door and window frame and leaf. This ensures proper alignment and functionality. Secondly, the connection method of the hinge must be suitable for the material of the frame and leaf. For instance, when using a hinge with a steel frame wooden door, one side of the hinge should be welded to the steel frame while the other side is fixed with wood screws onto the wooden door leaf.

Furthermore, it is necessary to verify if the hinge groove perfectly matches the height, width, and thickness specifications of the hinge. This guarantees a secure and stable fit. During the installation process, it is also important to ensure that the axes of the hinges on the same leaf are aligned on the same vertical line. This prevents any unwanted movement or springing up of the door or window leaves.

Additionally, it is crucial to check the compatibility between the hinge and the screws and fasteners used for its installation. Proper matching ensures a secure and reliable connection. In cases where the two leaf plates of the hinge are asymmetrical, it is necessary to determine which leaf plate should be connected to the fan and which should be connected to the door and window frame. The side connected to the three sections of the shaft should be fixed to the frame, while the side connected to the two sections of the shaft should be fixed to the door and window frame.

In conclusion, spring hinges provide essential functionality for various types of doors, cabinets, and wardrobes. Their adjustability, durability, and specialized variations make them a popular choice in the construction and furniture industries. Proper installation, considering factors such as compatibility, alignment, and connection methods, is crucial to ensure the optimal performance of spring hinges. Whether it's a hollow door, cabinet door, or wardrobe door, selecting the appropriate spring hinge will greatly enhance the quality and longevity of the furniture piece.
