Extended Information:
When selecting a cabinet hinge, consider the following key points:
1. Material: Look for hinges made of cold-rolled steel, as they are durable and have a strong load-bearing capacity. They should also have a smooth surface and a thick coating to resist rust. Avoid inferior hinges made of thin iron sheets, as they can lose their elasticity and eventually cause the door to not close tightly.
2. Hand feel: High-quality hinges should have a soft opening force and a uniform rebound force when closed partially. This indicates their durability and convenience of use. Inferior hinges may have a short service life, fall off easily, and have poor overall quality.
To repair the connection between the cabinet door and the hinge, follow these steps:
1. Open the door and lift it up while holding onto it. This might require some effort, but it will allow you to lift the door out of its hinges.
2. Clean the rusted area using anti-rust oil and lubricating oil. Apply the oils to remove any rust build-up and improve the door's movement.
3. Screw off the old hinge and replace it with a new one. Secure the new hinge using screws and tighten them to ensure a secure connection.
Remember to choose a hinge that matches the original hinge's style and size to maintain consistency and proper functionality.

The hinge of the Panpan anti-theft door plays a crucial role in ensuring the security and stability of the door. The hinge is the component that allows the door to rotate or swing open and closed. In the case of the anti-theft door, the hinge must be designed in a way that prevents unauthorized access and tampering.
There are two basic structures of hinges used in anti-theft doors: light hinges and dark hinges. The light hinges are exposed and can be easily accessed from the outside, making them vulnerable to destruction or tampering. On the other hand, the dark hinges are concealed and cannot be touched from the outside. This adds an extra layer of security as it prevents intruders from gaining access to the hinge and attempting to manipulate it.
However, concealed hinges have a drawback. Due to their design, the door can only be opened up to a maximum of 90 degrees. Opening the door further than that can damage the hinge. This limitation is a trade-off for enhanced security. On the other hand, open hinges allow for a full 180-degree opening, providing more convenience but compromising on security.
The choice of hinge structure for an anti-theft door depends on the security level required. High-end anti-theft doors, classified as Class A, typically use open hinges. However, measures are taken to ensure that even if the hinge is broken, the door cannot be opened. This could involve additional locks, reinforced frames, or other security features.
In most cases, residential anti-theft doors use hidden hinges, which offer a balance between security and convenience. The hidden hinge provides a clean and streamlined appearance while maintaining a high level of protection against unauthorized access.
Overall, the hinge structure of an anti-theft door is a crucial component in ensuring the security and functionality of the door. It determines the level of access and convenience while also safeguarding against tampering and break-ins. By selecting the appropriate hinge structure, homeowners can enhance the security of their premises and protect their property.

to the Installation Method of Spring Hinges: Step-by-Step Guide
Spring hinges are a type of hinge that automatically closes the door after it is opened. They are equipped with a spring and an adjusting screw, which allows for the adjustment of the height and thickness of the plates in various directions. There are two types of spring hinges: single spring hinges that only open in one direction, and double spring hinges that can be opened in both directions.
Before installing spring hinges, it is important to ensure that the hinge matches the door and window frame and the door leaf. Check if the hinge groove matches the height, width, and thickness of the hinge, and also check if the hinge and the screws and fasteners connected to it are matched.
The method of connecting the spring hinge should match the material of the frame and leaf. For example, if the hinge is used for a steel frame wooden door, the side connected to the steel frame should be welded, while the side connected to the wooden door leaf should be fixed with wood screws. If the leaf boards are asymmetrical, it is important to identify which leaf board should be connected to the fan and which leaf board 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, and the side connected to the two shaft sections should be fixed to the door and window.
To install the spring hinge, follow these steps:
1. Insert a 4mm hexagonal key into the hole at one end of the hinge and press it firmly to the end while opening the hinge.
2. Install the hinges into the hollowed-out grooves on the door leaf and door frame using screws.
3. Close the door leaf and make sure the spring hinges are in the closed state. Insert the hexagonal key again without pressing it down, and turn it clockwise to rotate. You should hear the sound of the gears meshing four times. It is important not to exceed four times because twisting the spring beyond its limit can damage it and cause it to lose its elasticity when the door leaf is opened.
4. After tightening the hinge, make sure the opening angle does not exceed 180 degrees.
5. If you want to loosen the hinge, simply follow the same procedure as in step 1.
The recommended spring hinges are designed with a spring device, which allows for a wider scope of application compared to ordinary hinges. They are commonly used on spring doors. When choosing a spring hinge, consider the door type, door frame material, shape, and installation direction.
Cabinet Hinges Installation Method: Step-by-Step Guide
The installation of cabinet hinges is also an important process. Follow these steps to install cabinet hinges properly:
1. Measure the size and edge of the cabinet door and mark them accurately.
2. Drill holes on the door panel. The depth of the hole should not exceed 12mm.
3. Insert the hinge into the hinge cup, and then put the hinge on the door panel hole of the cabinet and fix it.
4. Check whether the hinge can be used normally by opening and closing the cabinet door.
It is important to note a few things when installing cabinet hinges:
- Avoid situations where multiple hinges share the same side panel. If this cannot be avoided, provide an appropriate spacing when drilling to avoid multiple hinges being fixed at the same position.
- When installing the hinge, ensure that the hinge connection part, length, and width are consistent. If the covering distance of the fixed machinery is reduced, consider choosing a hinge with a curved hinge arm.
- Check whether the hinge screw matches the fastener, and select the appropriate hinge according to different conveying levels.
- When installing the hinge, ensure that the hinges on the same leaf are on the same vertical line to avoid instability and misplacement of the mechanical objects.
Sometimes, cabinet doors become tight due to frequent use, causing the hinges to loosen. In this case, a simple adjustment can solve the problem. Using a screwdriver, loosen the screw that fixes the hinge base, slide the hinge arm to the correct position, and then tighten the screws again.
In conclusion, the installation of spring hinges and cabinet hinges requires careful attention to detail. By following the step-by-step guides provided, you can ensure proper installation and achieve satisfactory results.
