[0044] Referring to Figure 1As shown, in some embodiments, one side of the first folding piece 1 is provided with a first recess 11, one side of the second folding piece 2 is provided with a first protruding part 21 matched with the first recess 11, the first protruding part 21 can be inserted into the first recess 11, and the end of the first protruding part 21 is rotatably connected with the inner wall of the first recess 11; for example, the first recess 11 can be arranged in the middle of one side of the first folding piece 1, and the first protruding part 21 can be arranged in the middle of one side of the second folding piece 2. The other side of the second folding piece 2 is provided with a second protruding part 22, one side of the third folding piece 3 is provided with a second recess 31 matched with the second protruding part 22, the second protruding part 22 can be inserted into the second recess 31, and the end of the second protruding part 22 is rotatably connected with the inner wall of the second recess 31; for example, the second protruding part 22 can be arranged in the middle of the other side of the second folding piece 2, and the second recess 31 can be arranged in the middle of one side of the third folding piece 3. The other side of the third folding piece is provided with a third protruding part 32, one side of the fourth folding piece 4 is provided with a third recess 41 matched with the third protruding part 32, the third protruding part 32 can be inserted into the third recess 41, and the end of the third protruding part 32 is rotatably connected with the inner wall of the third recess 41; for example, the third protruding part 32 can be arranged in the middle of the other side of the third folding piece, and the third recess 41 can be arranged in the middle of one side of the fourth folding piece 4.
[0045] Referring to Figure 2 As shown, in some embodiments, one side of the first folding piece 1 is provided with a first recess 11, one side of the second folding piece 2 is provided with a first protruding part 21 matched with the first recess 11, the first protruding part 21 can be inserted into the first recess 11, and the end of the first protruding part 21 is rotatably connected with the inner wall of the first recess 11; for example, the first recess 11 can be arranged in the middle of one side of the first folding piece 1, and the first protruding part 21 can be arranged in the middle of one side of the second folding piece 2. The other side of the second folding piece 2 is provided with a second protruding part 22, one side of the third folding piece 3 is provided with a second recess 31 matched with the second protruding part 22, the second protruding part 22 can be inserted into the second recess 31, and the end of the second protruding part 22 is rotatably connected with the inner wall of the second recess 31; for example, the second protruding part 22 can be arranged in the middle of the other side of the second folding piece 2, and the second recess 31 can be arranged in the middle of one side of the third folding piece 3.

It also effectively avoids the rotating position of the second folding piece 2 and the third folding piece 3 from moving towards the outer side of the wall 400 to be folded, blocking the door frame, and blocking the curtain wall hidden door 300 from closing and returning. Similarly, referring to Figure 1As shown, the second magnetic part 33 can be arranged on the side of the keel 100 facing the inner side of the wall surface, and the second magnetic part 33 is magnetically repulsive with the keel 100 of the inner side of the wall surface.
[0047] Referring to Figure 1 As shown, the first folding piece 1 is provided with at least one first mounting hole 12 for connecting with the keel 100 of the inner side of the wall surface, and the first bolt can pass through the first mounting hole 12 and connect with the keel 100 of the inner side of the wall surface, so that the first folding piece 1 is fixed flat on the surface of the keel 100 of the inner side of the wall surface.
[0048] Referring to Figure 1 As shown, the fourth folding piece 4 is provided with at least one second mounting hole 42 for connecting with the keel 200 of the curtain wall hidden door, and the second bolt can pass through the second mounting hole 42 and connect with the keel 200 of the curtain wall hidden door, so that the second folding piece 2 is fixed flat on the surface of the keel 200 of the curtain wall hidden door.
[0049] Referring to Figure 1 As shown, in some embodiments, the corners of the first folding piece 1, the second folding piece 2, the third folding piece 3 and the fourth folding piece 4 are transitioned by a circular arc.
[0050] Referring to Figures 3-8 As shown, the embodiment further provides a door body comprising the stone curtain wall hidden door folding hinge, and one or more stone curtain wall hidden door folding hinges can be arranged on the upper and lower parts of the door body, and are evenly distributed on the door body to maintain the balance of the overall rotation of the door body.
