[0039] As shown in Figure 4 and Figure 5As shown, in addition, the embodiment also provides a door and window system, which comprises the hanging body as described above, and further comprises an upper rail and a door and window leaf, the door and window leaf is provided with an upper frame 8, the upper frame 8 is provided with a fixing groove 81, the first metal piece 1 is fixed in the fixing groove 81, and the hanging rod 3 is connected to the upper rail. In this way, when the hanging body is installed, the first metal piece 1 can be first fixed in the fixing groove 81, and then the installation positions of the hanging rod 3 and the second metal piece 2 relative to the first metal piece 1 are synchronously adjusted through the sliding fit of the hanging rod 3 and the first adjusting groove 12, and after the positions of the hanging rod 3 and the second metal piece 2 are adjusted, the second metal piece 2 and the fixing groove 81 are fixed to each other to complete the installation. In this way, by optimizing the installation process, the installation difficulty is reduced, so that non-professionals can also easily complete the installation work, which not only saves the time and effort of the user, but also improves the satisfaction of the user.

[0040] Specifically, in the embodiment, the fixing groove 81 has a lower groove wall 811 and a limiting wall 812, and the limiting wall 812 is oppositely arranged with the lower groove wall 811.

[0041] As shown in Figure 1 , Figure 4 and Figure 5 , preferably, in the embodiment, the first metal piece 1 is provided with a first pressing edge 11, and the hanging body further comprises a first screw 4, the first screw 4 is connected to the first metal piece 1 and extends out of the bottom of the first metal piece 1, and as the first screw 4 is screwed in, the bottom end of the first screw 4 can abut against the lower groove wall 811, the lower groove wall 811 generates a reaction force on the first screw 4, gradually lifts the first metal piece 1 up, and makes the first pressing edge 11 press against the limiting wall 812 of the fixing groove 81, so as to fix the first metal piece 1 on the fixing groove 81. In this way, on the one hand, the screwing-in process of the first screw 4 provides an intuitive indication for the installer, and by observing the screwing-in degree of the first screw 4 and the fit of the first pressing edge 11 and the limiting wall 812, the installer can quickly judge whether the first metal piece 1 has been correctly installed and fixed, which simplifies the installation process and reduces the installation difficulty; on the other hand, compared with the traditional fixing method, in the embodiment, no additional fixing piece or complex adjustment steps are required, and only by screwing in the first screw 4, the quick fixing of the first metal piece 1 and the fixing groove 81 can be realized, which not only saves the installation time, but also improves the installation efficiency; on the other hand, the design of the first pressing edge 11 and the first screw 4 enables the hanging body to adapt to different sizes of the fixing groove 81, and by adjusting the screwing-in depth of the first screw 4 and the pressing degree of the first pressing edge 11, the hanging body can be stably fixed in the fixing groove 81 of different sizes, which enhances the versatility and flexibility of the hanging body, and when the hanging body needs to be maintained and replaced, the first metal piece 1 can be easily removed by unscrewing the first screw 4, which simplifies the maintenance and replacement process and reduces the maintenance cost and time cost.

[0042] As shown in Figure 1 , Figure 4 and Figure 5 , preferably, in the present embodiment, the second sheet metal part 2 is provided with a second pressing edge 21, and the hanger further comprises a second screw 5 connected to the second sheet metal part 2 and extending out of the bottom of the second sheet metal part 2. As the second screw 5 is screwed in, the bottom end of the second screw 5 can abut against the lower groove wall 811, which generates a reaction force on the second screw 5, gradually lifting the second sheet metal part 2 and pressing the second pressing edge 21 against the limiting wall 812 of the fixing groove 81, thereby fixing the second sheet metal part 2 on the fixing groove 81. In this way, on the one hand, the screwing-in process of the second screw 5 provides an intuitive indication for the installer, who can quickly determine whether the second sheet metal part 2 has been correctly installed and fixed by observing the degree of screwing-in of the second screw 5 and the fit of the second pressing edge 21 against the limiting wall 812, thus simplifying the installation process and reducing the installation difficulty. On the other hand, compared with the traditional fixing method, the present embodiment does not require additional fixing parts or complex adjustment steps, but only needs to screw in the second screw 5 to achieve quick fixing of the second sheet metal part 2 on the fixing groove 81, which not only saves installation time but also improves installation efficiency. On the other hand, the design of the second pressing edge 21 and the second screw 5 enables the hanger to adapt to fixing grooves 81 of different sizes, and by adjusting the screwing-in depth of the second screw 5 and the pressing degree of the second pressing edge 21, the hanger can be stably fixed in fixing grooves 81 of different sizes, thus enhancing the versatility and flexibility of the hanger. Moreover, when the hanger needs to be maintained or replaced, the second sheet metal part 2 can be easily removed by loosening the second screw 5, thus simplifying the maintenance and replacement process and reducing the maintenance cost and time cost.

[0043] It should be noted that in the existing sliding door design, the linkage door is a special type characterized by the opening and closing action of one door leaf driving other door leaves to open and close synchronously. The linkage door is widely used in various occasions due to its unique synchronous opening and closing characteristics, especially in high-end places such as lobbies. Such linkage doors are usually composed of multiple door leaves, each moving along an independent track and connected to each other through a linkage device (specifically including a belt, a pulley and a linkage part 6, etc.).

[0044] As shown in Figure 1 , Figure 4 and Figure 5As shown, preferably, in this embodiment, the hanging body further comprises a linkage member 6, which is arranged on the first sheet metal member 1 and is used to connect adjacent two sashes of the linkage door, specifically, the linkage member 6 is used to wrap around the belt. In this way, by arranging the linkage member 6 directly on the first sheet metal member 1, additional supports or connecting members can be avoided, thereby reducing the overall component quantity, which not only reduces the manufacturing cost, but also simplifies the assembly process, and the integrated design makes the space utilization between the linkage member 6 and the sheet metal member more efficient, reducing unnecessary space occupation, which is particularly important in space-limited installation environments.

[0045] As shown in Figure 1 , Figure 3 and Figure 5 , preferably, in this embodiment, the linkage member 6 is slidingly connected to the first sheet metal member 1, and the linkage member 6 can be adjusted in position relative to the first sheet metal member 1. With this arrangement, on the one hand, the installer can accurately adjust the position of the linkage member 6 on site according to the actual situation, without the need for prior accurate measurement or customized components, improving the flexibility and efficiency of installation, and this design allows easy adaptation to various installation scenarios, ensuring that the linkage door can work normally under various conditions; on the other hand, the linkage member 6 can be adjusted in position on the first sheet metal member 1, so that the installer can accurately position the linkage member 6 at the optimal position to ensure the best synchronization performance and stability, and by adjusting the position of the linkage member 6 on site, small errors caused by manufacturing, installation or other factors can be compensated for, thereby improving the overall accuracy of the system; on the other hand, the sliding connection design simplifies the installation steps, reduces the tools and installation time required, and improves the installation efficiency, and in the later maintenance process, if it is necessary to adjust the position of the linkage member 6, it is only necessary to simply slide the linkage member 6 to a new position and fix it, without the need to disassemble the entire system, thereby reducing maintenance costs and time.

[0046] It should be noted that in some other embodiments, the linkage member 6 can also be slidingly connected to the second sheet metal member 2, and the linkage member 6 can be adjusted in position relative to the second sheet metal member 2, which can be selected according to actual needs.

[0047] As shown in Figure 1 , Figure 3 and Figure 5As shown, preferably, in this embodiment, the linkage 6 is provided with a second adjusting groove 61, and the first sheet metal member 1 is provided with a guide rod 13, and the second adjusting groove 61 and the guide rod 13 are in sliding fit to provide guidance for the sliding of the linkage 6 relative to the first sheet metal member 1. In this way, on the one hand, the sliding fit of the guide rod 13 and the second adjusting groove 61 can ensure that the linkage 6 moves along a predetermined path during sliding, avoiding installation errors caused by deviation or shaking, and accurate guidance helps to reduce the shaking and jitter of the linkage 6 during sliding, thereby improving the overall stability of the system; on the other hand, through the cooperation of the second adjusting groove 61 and the guide rod 13, the installer can easily adjust the position of the linkage 6 without the need for complex tools or steps, and this design allows the linkage 6 to be fine-tuned in different installation environments to adapt to different installation needs and scenarios; on the other hand, the sliding contact area between the guide rod 13 and the second adjusting groove 61 is relatively small, which helps to reduce friction and wear, thereby prolonging the service life of the components.

[0048] As shown in Figure 1 and Figure 3 preferably, in this embodiment, the guide rod 13 is a third screw, the first sheet metal member 1 is provided with a connecting screw hole, and the third screw is screwed into the connecting screw hole, and the nut of the third screw and the first sheet metal member 1 are clamped on both sides of the linkage 6. In this way, on the one hand, the third screw as the guide rod 13 is screwed into the connecting screw hole to achieve fastening connection with the first sheet metal member 1, enhancing the stability and reliability of the structure, and the nut and the first sheet metal member 1 are clamped on both sides of the linkage 6, forming a stable clamping structure, further improving the overall stability of the system; on the other hand, when the position adjustment of the linkage 6 is completed, only the third screw needs to be tightened to achieve the fixed connection of the linkage 6 and the first sheet metal member 1, without the need for additional fixing members or tools, and during later maintenance, if the position of the linkage 6 needs to be adjusted or other maintenance work is needed, only the third screw needs to be loosened to easily perform the operation.

[0049] As shown in Figure 5 and Figure 2As shown, preferably, in the present embodiment, the extension directions of the first adjusting groove 12 and the second adjusting groove 61 are both parallel to the horizontal direction, and the extension directions of the first adjusting groove 12 and the second adjusting groove 61 are perpendicular to each other. In this way, on the one hand, by setting the extension directions of the two adjusting grooves perpendicular to each other, the space can be more effectively utilized, avoiding interference and conflict between components, which helps to maintain the compactness and neatness of the system, and the vertical layout makes it easier for the installer to access and operate the adjusting grooves, thereby simplifying the installation and adjustment process; on the other hand, the vertical layout makes it easier for the installer to identify and locate the adjusting grooves, thereby quickly making the necessary adjustments. This helps to improve the efficiency of installation and maintenance, and since the extension directions of the adjusting grooves are clear and perpendicular to each other, the installer can more easily understand and follow the correct steps, thereby reducing the likelihood of installation errors.

[0053] 1) By using the first sheet metal part 1 and the second sheet metal part 2 to replace the traditional box body structure, the production cost is reduced, and more importantly, by setting the adjusting groove on the first sheet metal part 1 and slidingly connecting the hanging rod 3 to the adjusting groove, the position of the hanging rod 3 is flexibly adjusted, improving the flexibility and adaptability of door and window installation;

[0054] 2) The clamping action of the nut 31 and the limiting flange 32 ensures the stability of the hanging rod 3 after being adjusted to the desired position, and this design not only enhances the strength of the fixing structure, but also improves the connection stability between the hanging rod 3 and the first adjusting groove 12, effectively preventing loosening or displacement caused by external force or vibration;

[0055] 3) The cooperation of the nut 31 and the threaded segment makes the position adjustment of the hanging rod 3 simple and intuitive, and the installer only needs to loosen the nut 31 to easily release the relative position fixation of the hanging rod 3 and the first adjusting groove 12, so that the hanging rod 3 slides along the first adjusting groove 12 to adjust the installation position, and after reaching the desired position, the relative position of the hanging rod 3 and the first adjusting groove 12 can be locked by tightening the nut 31, simplifying the installation and adjustment process;
