Abstract
Description
Technical Field
[0001] This utility model relates to the field of integrated bathroom technology, and in particular to a bathroom folding door. Background Technology
[0002] Traditional bathroom doors are mostly hinged or sliding doors. Hinged doors require more space to open and are prone to colliding with other bathroom fixtures, affecting ease of use. While sliding doors save space, dirt tends to accumulate in the tracks, making cleaning difficult, and their sealing is generally not as good as folding doors, potentially leading to moisture leakage in the bathroom environment.
[0003] Folding doors in prefabricated bathroom units are doors installed within the overall bathroom space. They can be folded into several sections and combined. These doors are widely used due to their space-saving design, good ventilation, ease of use, and excellent moisture resistance. They maximize space saving; even in limited spaces, folding doors don't take up excessive room when open, making the bathroom more convenient. They promote air circulation, ensuring a clean and tidy bathroom, which is crucial for maintaining a healthy indoor environment and human well-being. They enhance the overall aesthetics of the bathroom while effectively preventing moisture corrosion, facilitating daily cleaning, and offering advantages such as quick installation, long service life, convenient maintenance, and an attractive appearance.
[0004] However, existing bathroom folding doors still have the following drawbacks: Some folding door connection structures are poorly designed, and connecting parts are prone to loosening, leading to problems such as shaking and abnormal noises during use, affecting the door's normal use and lifespan. Furthermore, the connection between the door and the frame is not stable enough, and the door may shift during frequent opening and closing. Traditional folding door sliding components, such as rollers and tracks, are prone to rust or blockage by dirt in the humid bathroom environment, affecting the smoothness of sliding, increasing opening and closing resistance, and even potentially causing damage to the sliding components, requiring frequent repairs or replacements. Existing bathroom doors often do not adequately consider cushioning protection during opening and closing, making them susceptible to damage from impacts to the door or surrounding facilities. Especially during the folding and unfolding of folding doors, the lack of suitable cushioning devices results in greater impact forces between the door panels or between the door and the frame, reducing the overall durability of the door.
[0005] In view of the above-mentioned defects in the existing technology, this patent technology aims to develop a new type of bathroom folding door, solve the problems of space utilization, installation and connection stability, sliding component reliability, buffer protection and component size specifications of folding doors in integrated bathrooms, and provide a bathroom folding door with high space utilization, stable connection, smooth sliding, buffer protection and optimized size specifications. Utility Model Content

The first folding door is located on the left side, and the second folding door is located on the right side. The right end of the first folding door and the left end of the second folding door are movably connected by a folding buckle and can be folded relative to each other. The side frames are vertically arranged to match the first and second folding doors, including a left side frame located on the left end and a right side frame located on the right end. The left and right side frames are located on the upper part of the bottom frame, and the top frame is horizontally connected to the left side frame and the second folding door. The upper part between the right side frames, the bottom frame, the top frame, the left side frame, and the right side frame surround the outer periphery of the first folding door and the second folding door to form a first receiving space for accommodating the first folding door and the second folding door. The upper left side of the first folding door and the upper right side of the second folding door are respectively connected to pulleys, and are respectively movably connected to the top frame through the pulleys. The lower left side of the first folding door and the lower right side of the second folding door are respectively connected to sliding parts, and are respectively movably connected to the bottom frame through the sliding parts. Under the combined action of the folding buckle, the sliding parts, and the pulleys, the first folding door and the second folding door can move to the left or right relative to the top frame to the end of the top frame and fold in front of the top frame and the bottom frame.
[0008] As a further explanation of this utility model:
[0009] Preferably, the folding buckle includes a folding body, a fastening part, and a flat stop part. The cross-section of the folding body is a convex shape with a rearward protrusion.
