[0038] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0039] like Figure 1 and Figure 2 As shown, a folding door comprises a door frame 1 and a door panel 2, wherein the door frame 1 comprises a lateral column 12 and a guide rail 11. Specifically, the guide rail 11 comprises an upper rail and a lower rail, and the upper rail and the lower rail are respectively provided with a slide groove 111.

[0040] like Figure 1 and Figure 2 As shown, the number of the door panels 2 is at least two, and the door panels 2 are distributed in sequence, and each two adjacent door panels 2 are connected by an intermediate connecting member 4. Figure 4 , Figure 6-Figure 10As shown, the intermediate connecting member 4 includes a first hinge unit 41, a second hinge unit 43 and a transition connecting block 42. The first hinge unit 41 and the second hinge unit 43 are respectively rotatably connected to the transition connecting block 42. The first hinge unit 41 is fixedly connected to one of the door panels 2, and the second hinge unit 43 is fixedly connected to the other door panel 2. A first gear 45 is fixedly provided on the first hinge unit 41, and a second gear 46 is fixedly provided on the second hinge unit 43. The first gear 45 meshes with the second gear 46.

[0041] As the door panel 2 moves, the first gear 45 and the second gear 46 rotate in coordination, ensuring that the door panel 2 moves synchronously to be opened and closed, and has good connection reliability and movement coordination.

[0042] Specifically, Figure 6 As shown, a buffer pad 44 is provided on the side of the transition connection block 42 facing the guide rail 11. This prevents the intermediate connection member 4 from colliding with the guide rail 11 during the closing process of the door panel 2 to produce abnormal noise, and reduces the possibility of collision damage.

[0043] like Figure 8-Figure 10 As shown, the intermediate connecting member 4 also includes a pre-tightening assembly 47, and the pre-tightening assembly 47 includes a fixed stop block 471 and a movable unit 472, and the movable unit 472 includes a movable protrusion and a pre-tightening elastic member; one of the fixed stop block 471 and the movable unit 472 is arranged on the transition connecting block 42, and the other is arranged on the first hinge unit 41 or the second hinge unit 43.

[0044] The pre-tightening unit may be disposed only on the first hinge unit 41 or the second hinge unit 43. In this embodiment, a pre-tightening assembly 47 is disposed between the first hinge unit 41 and the second hinge unit 43 and the transition connection block 42, respectively.

[0045] like Figure 8-Figure 10 As shown, specifically, the transition connection block 42 is provided with a receiving hole, the movable protrusion is slidably connected to the receiving hole, and the preload elastic member is arranged between the movable protrusion and the receiving hole. Under the push of external force, the movable protrusion can overcome the elastic force of the preload elastic member and return to the receiving hole. The corresponding first hinge unit 41 and the second hinge unit 43 are provided with guide grooves, and the fixed block 471 is arranged in the guide grooves.

[0046] When the folding door is closed, the movable protrusion and the fixed stopper 471 cooperate to limit the movement of the door panel 2, thereby ensuring that the closed state is maintained stably. When the folding door is opened, an external thrust is applied, and the movable protrusion overcomes the elastic force of the pre-tightening elastic member and separates from the fixed unit, so that the folding door is opened smoothly.

[0047] like Figure 1As shown in FIG. 2 , the first side plate 21 and the second side plate 22 are located on both sides of the door panel 2. The first side plate 21 is rotatably connected to the lateral column 12, and the second side plate 22 is provided with an external connecting member 5. Figure 5 , Figure 11-Figure 14 As shown, the outer connecting member 5 includes an outer roller 51, and the outer roller 51 is connected to the guide rail 11. The first side panel 21 is limited by connecting to the lateral column 12, and the second side panel 22 is limited by rolling connection with the guide rail 11 through the outer connecting member 5, and each door panel 2 is connected by the intermediate connecting member 4. When the folding door is opened or closed, the outer connecting member 5 and the intermediate connecting member 4 cooperate to guide the door panel 2 to move and realize folding and opening.

[0048] like Figure 11-Figure 14 As shown, the outer connecting member 5 includes a connecting seat 52 and a roller bracket 54. The connecting seat 52 is fixedly connected to the corresponding door panel 2, and the outer roller 51 is arranged on the roller bracket 54. A rotating shaft 55 is fixedly arranged on the connecting seat 52, and the roller bracket 54 is rotatably connected to the rotating shaft 55.

[0049] like Figure 1 As shown, specifically, the outer connecting member 5 corresponds to the upper rail and the lower rail one by one, and the outer roller 51 is arranged in the corresponding slide groove 111. The upper rail and the lower rail limit the door panel 2 at the same time, and the installation reliability of the door panel 2 is very good.

[0050] like Figure 12-14 As shown, further, a threaded hole 551 and a guide groove 552 are provided at one end of the rotating shaft 55, and the guide groove 552 is radially arranged to penetrate the rotating shaft 55. The external connecting member 5 also includes an axial adjustment mechanism 53, and the axial adjustment mechanism 53 includes an axial push block 532, an adjustment screw 531 and an adjustment elastic member 533. The axial push block 532 is slidably arranged in the guide groove 552 and radially extends out of the guide groove 552. The adjustment screw 531 is connected to the threaded hole 551 and axially limits the axial push block 532 in the guide groove 552. The adjustment elastic member 533 is arranged between the axial push block 532 and the roller bracket 54.

[0051] By rotating the adjusting screw 531, the axial position of the axial push block 532 can be adjusted, and then the position of the roller can be adjusted to achieve the overall up and down adjustment of the door panel 2, which can adapt to the installation error of the roller or adjust the up and down gap.

[0052] like Figure 1 and Figure 2 As shown, specifically, the first side plate 21 is connected to the lateral column 12 through a rotating connection member 3, as shown in FIG. Figure 3As shown, the rotating connector 3 includes a third hinge unit 31. A slot is provided on the lateral column 12, and the slot extends along the length direction of the lateral column 12. The rotating connector 3 is arranged in the slot, and a locking unit is provided between the third hinge unit 31 and the lateral column 12. The connection between the rotating connector 3 and the lateral column 12 is convenient and reliable. Example

[0053] like Fig.15 As shown, compared with the first embodiment, the difference of this embodiment is that: the door panel 2 further includes at least one group of intermediate panels 23, and the intermediate panels 23 are located between the first side panel 21 and the second side panel 22. There are two door panels 2 in each group of intermediate panels 23, and an intermediate roller is provided on the intermediate connecting member 4 between the two door panels 2 in the same group, and the intermediate roller is connected to the corresponding transition connecting member and is arranged in the slide groove 111.

[0054] For a door type with a larger width, an intermediate plate 23 can be added, and the number of door panels 2 can be increased to match the door type with a larger width. Example
