One side of the first door leaf 1 is laterally installed on a door frame 5 on one side by means of hinge connection. The second door leaf 2 is connected to the other side of the first door leaf 1 through a continuous hinge 6. One side of the third door leaf 3 is connected to the other side of the second door leaf 2 through a continuous hinge 6. The fourth door leaf 4 is arranged in a double-leaf opening manner with the third door leaf 3 and both sides of the fourth door leaf 4 are laterally installed on a door frame 5 on the other side by means of hinge connection. Among them, a top and bottom bolt 8 is provided between the second door leaf 2 and the third door leaf 3. By adopting continuous hinges at the joints between the door leaves, while ensuring the firm connection between the door leaves, the door posts are made of ultra-heavy-duty aluminum alloy, using high-quality high-strength aluminum alloy material, and are designed to be hidden, with high strength and relatively high bearing capacity according to the actual use requirements, avoiding safety problems during installation.

[0033] Furthermore, in this embodiment, a keel frame 17 is provided in each of the first door leaf 1, the second door leaf 2, the third door leaf 3, and the fourth door leaf 4, and a door panel or glass or acrylic board is installed inside the keel frame 17.

The fixing portions 11c are fixed in the fixing grooves of the doorpost 11 through screws 11. A clamping portion 11a is provided at the port of the fixing groove. The cover plate 12 is clamped on the clamping portion 11a. Through the above settings, it is beneficial to ensure the firmness of the connection. Among them, the door frame 5 is fixed in the fixing portions 11c through self-tapping screws 16. The width between the fixing portions 11c is the same as the width of one side of the door frame 5, which is beneficial to improve the firmness of the connection, reduce the gap at the connection, and ensure the sealing performance.

[0039] Further, in this embodiment, as Figure 6 shown, the continuous hinge 6 includes a fixed end 6a and a connecting end 6b. The connecting end 6b is provided with a bayonet and is inserted between two adjacent doors. Limiting protrusions for limiting are provided on both sides of the fixed end 6a. The continuous hinge 6 adopts an aluminum alloy continuous buckle ring method, and the middle connecting end 6b uses a plastic part for sealing and lubrication at the connection to ensure that there is no sound of metal friction when opening and closing.

[0040] Further, in this embodiment, adjustable nylon rollers are provided at the bottom of the first door leaf 1 or adjustable nylon rollers are provided at the bottom of the second door leaf 2 or adjustable nylon rollers are provided at the bottom of the third door leaf 3 or adjustable nylon rollers are provided at the bottom of the fourth door leaf 4, or adjustable nylon rollers are provided at the bottoms of the first door leaf 1, the second door leaf 2, the third door leaf 3, and the fourth door leaf 4. During long-term use, the door leaf will still sag due to its own weight. Affected by the gravity of the door and various structures of the factory building, adjustable nylon rollers are designed at the bottom of the door leaf to completely prevent the inconvenient use caused by the sagging of the door.

[0041] Compared with the prior art, the present application has the following technical effects:

[0042] In the present application, the connection between the door leaves is made by using a continuous hinge. Among them, while ensuring the firmness of the connection between the door leaves, the doorpost is made of ultra-heavy-duty aluminum alloy, using high-quality high-strength aluminum alloy material, and is designed to be hidden, with high strength and high bearing capacity according to the actual use requirements, avoiding safety problems during installation. At the same time, during long-term use, the door leaf will still sag due to its own weight. Affected by the gravity of the door and various structures of the factory building, adjustable nylon rollers are designed at the bottom of the door leaf to completely prevent the inconvenient use caused by the sagging of the door.

[0043] In this application, considering the later replacement and maintenance, the keel frame of the door leaf adopts the design of aluminum alloy keel. The keel frame can be connected by buckles, which is easy to replace and has good processing performance.

[0044] In this application, the door leaf, door frame and sealing strip all adopt engineering rubber and plastic to ensure elasticity and strength after installation.
