Expanding the article on the practice of self-closing doors in KFC bathrooms can be done by providing more detailed information and explanations about the different methods and materials used to achieve an invisible door. Additionally, you can discuss the benefits and drawbacks of each method, as well as provide examples and recommendations for the installation process.
Here is an expanded version of the article:
"The practice of using self-closing doors in KFC bathrooms has become increasingly popular in recent years. These doors provide convenience and enhance the overall experience for customers. In this article, we will explore several methods of achieving an invisible door, discussing the materials used, different closing mechanisms, and installation options.
When it comes to hiding the door, there are various materials that can be used. One option is to paste wallpaper over the door, which allows it to blend seamlessly with the surrounding walls. Another option is to use plasterboard, which can be painted or textured to match the overall design of the bathroom. Wood veneer is also a popular choice for achieving a more natural and luxurious look.
In terms of closing mechanisms, there are several options available. One common choice is a door closer, which uses a hydraulic system to control the speed and force of the door closing. This ensures a smooth and controlled closing motion, preventing any noise or accidents. Another option is a hydraulic hinge, which provides similar benefits but is integrated into the door itself. This eliminates the need for a separate closer and creates a sleeker and more minimalist appearance. Lastly, a touch bead can be used, which activates the closing mechanism when the door is pushed or pulled.
The installation method of the door can also vary depending on the space and design preferences. For instance, a horizontal opening door can be used, which swings open and closes like a traditional door. A sliding door is another option, which allows for space-saving and seamless movement within the bathroom. Additionally, a revolving door can be installed, which adds a unique and stylish touch to the overall design.
Now, let's discuss the phenomenon of the door shaft hinge in cabinet doors. The cabinet door is installed obliquely to ensure automatic closing after opening. There are a few reasons for this. Firstly, the cabinet body itself may not be perfectly vertical, causing the door to slowly close under the influence of gravity. Secondly, the door hinge used is a self-closing door hinge with buffer damping. This hinge is designed to keep the door closing slowly under the elastic force of the hinge, preventing any damage or injuries. It also maintains an appropriate inward closing force, ensuring the door stays closed securely.
In mechanics, the concept of moment of force about the axis can be applied to explain the functionality of the self-closing door hinge. The torsion spring within the hinge generates power by twisting and deforming, resulting in a piston moving back and forth in the oil cylinder. This generates a buffer force that controls the closing motion of the door. However, it's important to note that hydraulic hinges have their drawbacks, including their size, potential oil leakage, and decay of closing force over time. There are alternatives available, such as pneumatic hinges, which offer similar door-closing functions with better performance and cost-effectiveness.
To summarize, the practice of utilizing self-closing doors in KFC bathrooms is a great way to improve the overall customer experience. By using invisible door methods, such as various materials, closing mechanisms, and installation options, KFC ensures a seamless and functional bathroom design. The phenomenon of the door shaft hinge in cabinet doors can be explained through the concept of moment of force about the axis. It allows the doors to close automatically after opening, providing convenience and safety. For those looking for a reliable and efficient closing mechanism, pneumatic hinges are recommended due to their superior performance and cost-effectiveness."
In conclusion, the expanded article provides more comprehensive information about the different methods and materials used to achieve invisible doors, as well as explaining the phenomenon of the door shaft hinge in cabinet doors. It also introduces alternative options, such as pneumatic hinges, for those seeking a more reliable and cost-effective closing mechanism. The overall word count of the expanded article is higher than the original, providing more detailed insights and explanations for readers.

The slide rail wheels of sliding doors are typically installed in the upper track. While the pulley may be small, its importance is self-evident. In daily life, it is recommended to apply one or two drops of lubricating oil every 6 months to keep the wheels smooth. The pulley of the sliding door is divided into upper and lower wheels. The upper wheel uses needle bearings, so it does not require lubricating oil, but it should be cleaned regularly to remove any debris. However, for bearings or rubber wheels, it is necessary to apply lubricating oil to the sliding parts periodically.
Installation method of sliding door pulleys:
The use of sliding doors is very common, and they are available in various materials such as wood, metal, and glass. The installation of sliding doors is relatively simple, and the prices are moderate. There is a wide range of styles available to meet the basic needs of consumers. Among the components of sliding doors, the pulleys play a vital role. Here is a specific introduction to the installation method and recommendations for sliding door pulleys:
1. Installation method of sliding door pulley:
- First, set up the pulley at the upper end of the sliding door.
- Insert a 6mm hexagonal wrench from the round hole and loosen the screw.
- If the screw is difficult to turn, use the short end of the wrench to insert into the six inner holes of the screw for easier rotation.
- After loosening the screw, remove the upper pulley in parallel.
- Screw in new screws.
- Push the upper pulley flat into the gap between the screw cap and the inner wall of the door frame. To maintain a certain distance, place a piece of cardboard between the upper edge of the door frame and the plane of the upper pulley.
- Tighten the screws.
- Remove the cardboard after the upper pulley is installed.
- Flip the sliding door, stand it up, insert the screw through the round hole at the bottom, and press the lower pulley with your hand so that the screw hole of the adjustment block aligns with the screw and can be easily screwed in. Use a 5mm hexagonal wrench to tighten the screw.
- Once the screw is securely fastened, turn it five more times. At this point, the single side and lower pulleys of the sliding door are installed. Repeat the same method for other upper and lower pulleys.
2. Sliding door pulley manufacturers recommend:
- Shanghai Xiacun Trading Co., Ltd. is a reputable company that specializes in the production, processing, distribution, and wholesale of sliding door hardware, accessories, and other home-related products.

Additionally, titanium-magnesium-aluminum alloy sliding doors are a cost-effective and environmentally friendly option with a long service life. Plastic-steel sliding doors also provide better sealing performance and are less prone to deformation or aging.
If the pulley of a sliding door breaks within two months, there may be a quality issue. In such cases, it is important to address the issue with the manufacturer or supplier to resolve the problem. Some common problems with sliding doors include jamming and misalignment of the upper and lower grooves. To address these issues, it is recommended to repair or replace the faulty pulleys in a timely manner.
If the sliding door is stuck due to misaligned grooves, gently push the sliding door upwards to relieve pressure on the pulleys. This should allow the door to slide smoothly again. If the pulley itself is damaged and causing the door to become heavy and difficult to move, it is important to replace the pulleys promptly to avoid further damage to the door.
To repair broken sliding door pulleys, follow these steps:
1. Disassemble the sliding door: Lift one end of the sliding door vertically while holding the other end, and gently lift it out of the track. Repeat this process for the other end of the sliding door.
2. Remove the faulty pulley: Lay the sliding door flat on the ground and observe the wheels for any issues. Remove the wool strips covering the screw holes, and then unscrew and remove the pulley. Repeat this process for the upper and lower pulleys.
3. Install new pulleys: Place the sliding door upright and push the upper pulley into the gap between the screw cap and the inner wall of the door frame. Insert cardboard between the upper edge of the door frame and the plane of the upper pulley to maintain proper distance. Tighten the screws to secure the pulley. Repeat this process for the other pulleys.

One such example is hinges and hinges, which are commonly used to connect and enable movement between two parts of furniture. Although these terms are often used interchangeably, there are some differences between them.
Hinges are mainly used for windows and doors. They enable the opening and closing of these structures by connecting them to the frame. When it comes to windows, hinges allow for rotation only. On the other hand, hinges used for windows allow both rotation and translation. This means that the window sash can not only rotate but also move horizontally. Hinges can often be used as a substitute for hinges, but in certain cases, hinges are necessary. For example, inverted windows require hinges, while super-large casement windows may need multiple hinges to bear the force.
In terms of installation, hinges are typically used for doors and windows, while hinges are more commonly found in cabinets. They can be made from different materials, such as stainless steel or iron. There are also hydraulic hinges available, which offer a buffering effect and minimize noise.
When using hinges on windows, it is important to note that they might not provide enough friction to hold the window in place when it is open. Therefore, an additional support is often used to prevent the window from being blown back by the wind and potentially getting damaged. On the other hand, hinges have their own damping mechanism, allowing them to be used independently. The specific design of the hinge used on casement windows and upper swing windows may vary, including the length of the outer arm connected to the window frame.
In summary, while hinges and hinges are often used interchangeably, there are some differences between them. The main distinctions lie in their specific usage, load-bearing capacity, and the movements they enable. Hinges are commonly used for windows and doors, while hinges are more commonly found in cabinets. By understanding these differences and considering the specific requirements of your furniture, you can choose the appropriate hardware for your needs.

Expanding on the existing article, I will provide a more detailed analysis and explanation of the problem with ordinary sound-proof electromagnetic screen doors and the solutions that have been proposed.
Ordinary sound-proof electromagnetic screen doors are known to have a large self-weight and closing resistance. In addition, the hinges on these doors are easily deformed and damaged, which leads to unsatisfactory sound insulation and shielding performance. To address these issues, a comprehensive study was conducted on the screen door, hinges, and hinge shafts. Three-dimensional modeling and finite element analysis were employed to understand the distribution of stress, displacement, and safety factors of these components.
Through the analysis of the collected data and graphical parameters, the structure was redesigned and optimized to strengthen the strength of the hinges and hinge shafts. The strength of the hinge shaft was identified as particularly important for the overall performance of the door leaf applications.
Designing a soundproof screen door with weight reduction in mind was among the primary objectives. The frame of the door is typically made of rectangular steel pipe, using ordinary carbon steel, and filled with wooden boards for added insulation. To enhance the sound insulation effectiveness and reduce the weight of the door, thermal insulation cotton with a density of 30kg/m3 was used as filling, with a volume of 0.3m3.
After the initial production of the soundproof screen door, several issues were identified during inspection. Firstly, the hinges were difficult to turn and produced abnormal noises. Secondly, the door closing resistance was high and lasted for an extended period. To address these problems, a comprehensive analysis of the S81 and S201 hinges was conducted separately.
Under ideal conditions, motion analysis was performed on the S81 hinge. It was observed that when the door leaf and door frame formed an angle of approximately 25°, resistance started to appear during the closing action. As the door continued to close, a higher force was required to fully close it. When the S201 hinge was used instead of the S81 hinge, the problem was significantly improved. The S201 hinge was found to require less force and had a shorter duration of force application during the door closing process.
Based on these observations, it was concluded that the structure of the S201 hinge was more reasonable and better suited for workplaces requiring large door closing forces and superior sealing and sound insulation.
Subsequently, a detailed strength analysis was conducted on the S81 hinge structure. The 3D solid model of the hinge was created using SolidWorks software, and material properties were defined. Finite element analysis was performed on the hinge to understand its strength under various loads and working conditions.
The analysis showed that the maximum stress point occurred on the hinge shaft, close to the constraint end, reaching a value of 231MPa. This exceeded the allowable stress limit, indicating the need for material and structural redesign. The upper hinge shaft also had the minimum safety factor, indicating a need for improvement.
The upper and lower hinges were found to meet the strength requirements, while the hinge shafts required optimization. The upper hinge shaft was redesigned by increasing the diameter from 9.5mm to 15mm, resulting in a maximum stress point of 101MPa and a safety factor greater than 2. The lower hinge shaft was also thickened to 15mm and met the strength and safety requirements.
Verification of the hinge strength showed that both the upper and lower hinges met the actual needs, with maximum stress points of 29MPa and 22MPa, respectively.
In conclusion, this study successfully identified the issues with ordinary sound-proof electromagnetic screen doors and proposed solutions. Through comprehensive analysis, the strength and reliability of the hinges and hinge shafts were improved, meeting the required standards. These enhancements contribute to the overall performance and effectiveness of sound insulation and shielding in screen doors.
