[0038] Please see Figures 1-9In this embodiment of the utility model, a folding door is characterized in that the folding door includes a first door panel 6, a second door panel 7, and a pulley hinge device 8. The first door panel 6 is hinged to the second door panel 7. At least two sets of pulley hinge devices 8 are installed on the first end face 61 of the first door panel 6. The pulley hinge device 8 includes: a pulley seat 1, a pulley, and a mounting base 5. The front end face of the pulley seat 1 is provided with a connecting plate 12 for mounting the pulley. The pulley is rotatably mounted on the connecting plate 12. The right end face of the mounting base 5 is hinged to the left end face of the pulley seat 1. The left end face of the mounting base 5 is detachably connected to the first end face 62 of the first door panel 6. Specifically, the first door panel 6 includes a first end face 62 for mounting the mounting base 5. The connection relationship between the first end face 62 and the mounting base 5 includes, but is not limited to, threaded connection, snap-fit ​​connection, adhesive connection, and mortise and tenon connection.

[0039] The working principle of this embodiment is as follows: the connection between the first door panel 6 and the ear plate 52 allows one end of the folding door to move synchronously with the pulley 3 at the pulley hinge device 8. When the operator drags one side of the second door panel 7 to the left, the first door panel 6 and the second door panel 7 can be fully unfolded. When the operator drags the second door panel 7 to the right, the first door panel 6 and the second door panel 7 fold together. When the operator continues to drag the second door panel 7, the second door panel 7 drives the first door panel 6 to move to the right. At this time, the overall area occupied by the folding door becomes smaller, which is the optimal folded state.

[0040] Further as Figures 1-7 As shown in the embodiment of this utility model, the pulley seat 1 is further provided with a snap-fit ​​device, which includes a guide wheel plate 11 and a guide wheel 2. The guide wheel plate 11 is installed on the front end face of the pulley seat 1. The horizontal height of the connecting plate 12 is not higher than that of the guide wheel plate 11. The guide wheel 2 is rotatably mounted on the guide wheel plate 11. The upper and lower ends of the guide wheel 2 are respectively provided with snap-fit ​​blocks 21. The width of the left and right sides of the guide wheel 2 is equal to the diameter of the pulley 3. Wherein, as... Figure 6-7 As shown, there is a height difference between the connecting plate and the guide wheel plate, and the horizontal height of the connecting plate is not higher than the horizontal height of the guide wheel plate.

[0041] like Figure 2 As shown, the guide wheel has locking blocks at both its upper and lower ends for rotating during installation, allowing the locking blocks to engage with the guide rail. The locking blocks at the guide wheel can be formed by machining or casting.

[0042] The working principle of this embodiment is as follows: Figure 3The end face height of the connecting plate 12 shown is not higher than that of the guide wheel plate 11. The guide wheel 2 is a rotatable structure. When installing the pulley hinge structure, the installer first rotates the guide wheel 2 so that the left and right sides of the guide wheel 2 are engaged in the through groove 42. Then, the installer continues to move the guide wheel 2 so that it moves to the hollow inner hole 41. The installer rotates the guide wheel 2 so that the locking blocks 21 at both ends of the guide wheel 2 are engaged in the hollow inner hole 41. The wheel surface of the pulley 3 is just in contact with the left and right sides of the through groove 42, so that the pulley 3 can slide in the through groove 42.

[0043] Further as Figure 1 As shown in the embodiment of this utility model, the guide wheel plate 11 and the connecting plate 12 are integrally formed. The connection method between the guide wheel plate 11 and the connecting plate 12 includes, but is not limited to, machining, die casting, and casting.

[0044] Further as Figures 1-7 As shown in the embodiment of this utility model, the mounting base 5 includes a hinge joint 51 and an ear plate 52. The right end face of the hinge joint 51 is hinged to the left end face of the pulley seat 1, and the ear plate 52 is detachably mounted on the first end face 62 of the first door panel 6. Specifically, as shown... Figure 1 As shown, the mounting base rotates around the front-to-back axis.

[0045] Further as Figures 4-8 As shown in this embodiment of the present invention, a hidden hole 61 is provided on the first end face 62 of the first door panel 6 near the hinge joint 51. The hinge joint 51 is fitted into the hidden hole 61 so that the left end face of the ear plate 52 abuts against the first end face 62 of the first door panel 6. Specifically, the size of the hidden hole 61 is not smaller than the size of the hinge joint 51. When the operator installs the hinge joint 51 to the first door panel 6, the hinge joint 51 is inserted into the hidden hole 61 so that the ear plate 52 abuts against the end face of the first door panel 6. The ear plate 52 can be installed onto the first door panel 6 by setting screws. By setting the hidden hole 61, the first door panel 6 can fit more snugly against the slide rail 4, and on the other hand, the overall folding door is more beautiful and simple.

[0046] Further as Figure 9 As shown in the embodiment of this utility model, the second door panel 7 is provided with a handrail 71, which is detachably installed on the front end face of the second door panel 7. The handrail 71 facilitates gripping and improves the ease of use of the folding door.

[0047] Further as Figure 6 As shown in the embodiment of this utility model, the folding door is provided with at least one hinge 72, and the hinge 72 is detachably located at the hinge joint of the folding door. Figure 6As shown, spring hinges can be used to hinge the first door panel and the second door panel. The specific working principle of the spring hinge is detailed in patent CN221682741U, and will not be repeated here.

[0048] Further as Figures 6-11 As shown in the present invention, a multi-folding door assembly structure includes the aforementioned folding door. The multi-folding door assembly structure includes at least two sets of folding doors and slide rails 4. The slide rails 4 are respectively installed horizontally at the upper and lower ends of the folding doors, and the pulley hinge device 8 is slidably connected to the slide rails 4.

[0049] like Figures 10-11 As shown, by setting up a multi-folding door combination structure, multiple sets of folding doors are installed together at the slide rail. When using the device, the operator can freely select which folding doors to open or close, realizing the opening and closing of some folding doors. The overall use is more flexible and can adapt to the needs of more scenarios.

[0050] Further as Figures 3-5 As shown in the embodiment of this utility model, the slide rail 4 has a hollow inner hole 41 inside, and a through groove 42 is opened on the lower end face of the slide rail 4 to connect the hollow inner hole 41 for sliding installation of the pulley seat 1. The width of the through groove 42 is equal to the diameter of the pulley 3. The snap-fit ​​block 21 is snapped into the hollow inner hole 41 so that the pulley 3 slides in the through groove 42.

[0051] Further as Figures 1-3 and Figures 6-7 As shown, there is a height difference between the guide wheel plate 11 and the connecting plate 12. Its function is to allow the guide wheel 2 at the guide wheel plate 11 to be installed at the hollow inner hole 41, so that the locking block 21 of the guide wheel 2 can be locked into the inner wall of the hollow inner hole 41. At this time, the pulley 3 installed on the connecting plate 12 is located at the through groove 42, and the pulley can slide in the through groove 42. This structure is simple. When installing, the operator only needs to rotate the guide wheel 2 to install the hinge structure of the pulley 3 on the slide rail 4.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
