[0002] Sliding doors are a common type of door in homes, referring to doors that can be pushed and pulled. With the development of technology and the diversification of decoration methods, sliding doors have evolved from traditional panel surfaces to glass, fabric, rattan, and aluminum alloy profiles. From sliding doors and folding doors to partition doors, the functions and applications of sliding doors are constantly expanding. Multi-track sliding doors, as the name suggests, have multiple tracks, allowing multiple sliding doors to move freely on these tracks. Thermally broken aluminum alloy sliding doors are one of the most common types of sliding doors.
[0003] However, when making multi-track solutions on the market, it is necessary to continuously splice thermal insulation strips. However, due to the working height limitation of the thermal break aluminum rolling machine, it is limited to a maximum of three or four tracks, and the width is difficult to increase, resulting in a large limitation on the number of tracks.

[0009] According to the above technical solution, a glass sliding door is installed between the indoor rails on the opposite side of the outdoor rail, and the side width of the glass sliding door is equal to the width of the connecting node.
[0010] According to the above technical solution, the two end faces of the outdoor rail, the indoor rail, and the connecting node are aligned with their corresponding end faces.
[0011] According to the above technical solution, a U-shaped clip is fastened between the splicing center rail and the splicing plate near the heat insulation strip.
[0012] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use;

The connecting node 3 includes a splicing middle track 31, a heat insulation strip 32, a splicing plate 33, a first hook 34, a splicing outer plate 35, a second hook 36, and a mating inner plate 37.
[0026] An indoor rail 2 is evenly distributed between one side of the outdoor rail 1 and the indoor rail 2. Both the outdoor rail 1 and the indoor rail 31 are connected to a splicing plate 33 via a thermal insulation strip 32. A U-shaped clip 6 is engaged between the splicing rail 31 and the splicing plate 33 near the thermal insulation strip 32 to enhance the connection strength and protect the thermal insulation strip 32. A first hook 34 is connected to the top of one side of the splicing plate 33, and a splicing outer plate 35 is connected to the bottom of one side of the splicing plate 33. A second hook 36 is connected between the indoor rail 2 and the splicing rail 31 near the first hook 34. The first hook 34 and the second hook 36 are interlocked. The splicing plate 33 and the first... A groove is provided at the connection point of the first hook 34, and the second hook 36 is engaged in the groove to facilitate the connection of the first hook 34 and the second hook 36. The inner rail 2 and the splicing middle rail 31 are connected to the splicing outer plate 35 by a mating inner plate 37. The splicing outer plate 35 and the mating inner plate 37 are connected by a connecting screw 4. The splicing outer plate 35 and the mating inner plate 37 are the same size and fit together to facilitate the connection of the splicing outer plate 35 and the mating inner plate 37. On the opposite side of the outer rail 1, there is an indoor rail 2, and glass sliding doors 5 are installed in sequence between them. The side width of the glass sliding door 5 is equal to the width of the connecting node 3 to facilitate the installation of the glass sliding door 5 after the connecting node 3 is assembled.
[0027] The working principle and usage process of this utility model are as follows: When splicing the tracks, first determine the outdoor track 1, and connect the splicing plate 33 to one side of the outdoor track 1 through the heat insulation strip 32. Then, connect the splicing middle track 31 to one side of the splicing plate 33 through the heat insulation strip 32 to complete the assembly of the connection node 3. Align the first hook 34 on one side of the splicing middle track 31 with the second hook 36 and snap it in place for temporary positioning. Then move the splicing outer plate 35 and the docking inner plate 37 to overlap. Fix the splicing outer plate 35 and the docking inner plate 37 with the connecting screws 4 to complete the assembly of the outdoor track 1 and the connection node 3. In the above manner, splice and combine multiple connection nodes 3 in sequence until the required number of tracks is met. Then, snap the second hook 36 of the indoor track 2 with the first hook 34 of the splicing middle track 31. Connect the docking inner plate 37 of the indoor track 2 and the splicing outer plate 35 of the splicing middle track 31 with the connecting screws 4 to complete the multi-track combination operation.
