Self-closing door spring hinge (the practice of KFC bathroom self-closing door) 2

Expanding on the topic of the practice of self-closing doors in KFC bathrooms, there are several ways to achieve an invisible door. After the completion of a renovation or decoration, there may be some regrets or detours when it comes to implementing an invisible door. However, there are various methods that can be summarized to provide reference and guidance for those interested in achieving an invisible door in their own spaces.

When it comes to hiding the door, there are several options regarding the material used. The door can be pasted with wallpaper, plasterboard, or wood veneer, depending on the desired aesthetic. This allows the door to blend seamlessly with the surrounding walls and create a hidden appearance.

In terms of closing the door, there are different mechanisms that can be employed. One option is to use a door closer, which ensures that the door closes automatically after it has been opened. Another option is to use a hydraulic hinge, which provides a buffer damping effect and allows for a controlled and gradual closing of the door. Lastly, a touch bead can be utilized to achieve a self-closing effect, where the door can easily be nudged or pushed to close without the need for additional hardware.

Furthermore, there are various installation methods that can be considered. The door can be designed to open horizontally, similar to a traditional swinging door. Alternatively, a sliding door mechanism can be implemented, allowing the door to smoothly glide to the side for opening and closing. Additionally, a revolving door can be utilized, providing a unique and stylish way to enter and exit a space.

In the case of cabinet doors, the door shaft hinge can be installed obliquely to achieve the automatic closing effect. This means that once the cabinet door is opened, it will slowly and automatically close without the need for manual intervention. This is particularly useful for cabinet doors that require frequent opening and closing.

To explain the concept using mechanics principles, the application of the moment of force about the axis can be considered. In the case of the cabinet door, the oblique installation of the door shaft hinge creates a situation where gravity acts as a force in the direction of closing the door. This force, combined with the elastic force provided by the self-closing door hinge, results in the door closing slowly under a controlled and calibrated mechanism. This ensures that the cabinet door does not slam shut, preventing any damage or injury, while still maintaining an appropriate closing force to prevent the door from opening or closing unintentionally.

In conclusion, achieving an invisible door can be accomplished through various methods and considerations. From the choice of materials to the closing mechanisms and installation methods, careful planning and implementation can result in a seamless and concealed door. By understanding the principles of mechanics, such as the moment of force about the axis, one can further comprehend the mechanisms behind the self-closing effect in cabinet doors. Ultimately, the goal is to create a functional and aesthetically pleasing door that seamlessly integrates with its surroundings.
