[0006] A linear guide groove is provided in the inner cavity of the door frame and away from the door leaf side, and a limit block is provided on the top of the guide mechanism, and the limit block is slidably matched with the linear guide groove; a rotating device is provided in the inner cavity of the upper and lower frames of the door frame and at the end of the wall part, and when the limit block moves to the end of the door frame, it is matched and connected with the rotating device.
[0007] The rotating device includes a limit plate and a rotating plate. The limit plate is fixed in the inner cavity of the door frame. A circular hole is provided in the center of the limit plate. The rotating plate rotates in the circular hole. A groove is provided on the rotating plate and the limit plate. The groove and the linear guide groove are located on the same straight line and have the same width. The limit block can slide from the linear guide groove into the groove of the rotating plate.
[0008] The guide mechanism comprises a rotating shaft, a moving block and guide wheels. The rotating shaft is fixedly connected to the corresponding position of the door leaf, the rotating shaft passes through the center of the moving block, and guide wheels are arranged on both sides of the moving block.
[0009] Both sides of the opening groove of the door frame are arc structures, and the guide wheels roll along the arc structures.
[0010] The hidden folding door of the present application adopts the above structure and has the following advantages:
[0011] 1. The door frame extends out of the wall, and the door leaf can be hidden behind the wall after folding, thereby improving the overall aesthetic performance;
[0012] 2. The sliding and opening of the door leaf adopts a guide mechanism to move in the door frame, thus ensuring the smooth operation of the door leaf;
[0013] 3. A rotating disk structure is arranged at the end of the door frame, so that the door leaf can only rotate when it moves to the end position, and the door leaf cannot rotate at other positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 and Figure 2 As shown, a hidden folding door includes a door frame 1 and door leaves 2. The number of door leaves 2 is not less than two. In this embodiment, there are two door leaves, each door leaf 2 is arranged horizontally, and the folding parts of two adjacent door leaves 2 are connected by hinges; wherein the length of the door frame 1 is greater than the sum of the lengths of all door leaves, and the extra length of the door frame 1 extends to the wall; the door leaf is folded and stored at the corresponding position of the wall after opening.
[0021] like Figures 3 to 6 As shown, the cross-section of the door frame 1 is a rectangular structure with a slot at one end, and the open slot corresponds to the upper and lower end surfaces of the door leaf 2; each door leaf 2 is provided with at least one guide mechanism at the top and bottom, and the rotating shaft 11 extending from the guide mechanism is connected to the door leaf 2, and the guide mechanism drives the door leaf 2 to slide and cooperate with the door frame 1.
[0022] A linear guide groove 14 is provided in the inner cavity of the door frame 1 and on the side away from the door leaf 2, and a limit block 15 is provided on the top of the guide mechanism, and the limit block 15 slides in cooperation with the linear guide groove 14; a rotating device is provided in the inner cavity of the upper and lower frames of the door frame 1 and at the end of the wall part, and when the limit block 15 moves to the end of the door frame 1, it cooperates and connects with the rotating device.
[0023] The rotating device includes a limit plate 17 and a rotating plate 16. The limit plate 17 is fixed in the inner cavity of the door frame 1. A circular hole is provided in the center of the limit plate 17. The rotating plate 16 rotates in the circular hole. A groove is provided on the rotating plate 16 and the limit plate 17. The groove is located on the same straight line as the linear guide groove 14 and has the same width. The limit block 15 can slide from the linear guide groove 14 to the groove of the rotating plate 16.
[0024] The guide mechanism includes a rotating shaft 11, a moving block 12 and a guide wheel 13. The rotating shaft 11 is fixedly connected to the corresponding position of the door leaf 2. The rotating shaft 11 passes through the center of the moving block 12. Guide wheels 13 are provided on both sides of the moving block 12. The two sides of the opening groove of the door frame 1 are arc structures, and the guide wheel 13 rolls along the arc structure.
[0025] When the door leaf 2 of the hidden folding door is in the closed state, the door leaf 2 is arranged in parallel at the doorway. When the door leaf 2 needs to be opened, the door leaf is first translated as a whole to the end of the door frame, and the limit block 15 at the top of the door leaf enters the rotating disk 16, so that the moving block 12 does not rotate, and the rotating disk 16 rotates in the limit disk 17, completing the folding of the door leaf 2.
