[0002] In sliding door and window hardware systems, the load-bearing components of the hardware play a crucial role in supporting the load on the door leaf. The smoothness of the sliding mechanism directly affects the force required to slide the door leaf. Currently, most bearings are roller or needle roller bearings, which generate direct vibration and noise during the sliding process on the door frame track. Furthermore, the heavy door leaf is difficult to slide, resulting in a poor user experience. Utility Model Content

[0003] In view of the above problems, this utility model provides a magnetic load-bearing device and a door / window that overcomes the problems of high vibration and noise and difficulty in pushing and pulling.

The load-bearing slider includes a plurality of slider units and a plurality of connecting plates connected in series with the plurality of slider units. The connecting plates are connected to guide members. The slider units attract each other with a track assembly disposed on a frame. The guide members abut against the track assembly to prevent the slider units from contacting the track assembly, thereby forming magnetic levitation between the slider units and the track assembly.

[0005] Optionally, the load-bearing slider further includes a slider fixing cover, which is connected to the fan body. The slider fixing cover covers the outside of several slider units and several connecting plates, and the several connecting plates are respectively connected to the slider fixing cover.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] See Figure 1-7This embodiment provides a door / window, including a frame 2, a sash 3, and a magnetic load-bearing device 1. The magnetic load-bearing device 1 is located between the frame 2 and the sash 3 to achieve a magnetic levitation connection between the frame 2 and the sash 3. In this solution, the magnetic load-bearing device 1 achieves a magnetic levitation connection between the track assembly and the load-bearing slider 20, ensuring frictionless sliding of the load-bearing slider 20. The guide component avoids direct contact between the magnet assembly and the track assembly, reducing noise and facilitating pushing and pulling.

[0032] The magnetic load-bearing device 1 in this solution can be applied to single-track or double-track doors and windows.

[0033] Specifically, the track assembly is connected to the frame 2; the magnetic load-bearing device 1 includes a load-bearing slider 20, which is connected to the fan body 3. The load-bearing slider 20 includes several slider units 21 and several connecting plates 22 connected in series with the slider units 21. The connecting plates 22 are connected to guide members. The slider units 21 attract each other to the track assembly, and the guide members abut against the track assembly to prevent the slider units 21 from contacting the track assembly to form magnetic levitation. In this solution, the guide members are set on the connecting plates 22, and two adjacent slider units 21 share one guide member, thereby reducing the use of guide members and saving costs.

[0034] In this embodiment, the load-bearing slider 20 also includes a slider fixing cover 24, which is connected to the fan body 3. The slider fixing cover 24 covers several slider units 21 and several connecting plates 22, and the several connecting plates 22 are respectively connected to the slider fixing cover 24. Several slider units 21 are connected to the connecting plates 22, and the connecting plates 22 are fixed to the slider fixing cover 24 to assemble a complete load-bearing slider 20. The slider fixing cover 24 facilitates the installation and transportation of the load-bearing slider 20 as a whole.

[0035] See Figure 4-6 The connecting plate 22 is provided with a first through groove 221, which extends toward the slider fixing cover 24.

The limiting portions 222 at both ends contact two adjacent slider units 21 respectively to achieve positioning of the slider unit 21.

[0037] In this embodiment, the load-bearing slider 20 further includes several clamping members 25. One end of each clamping member 25 is connected to the connecting plate 22, and the other end of each clamping member 25 passes through the connecting plate 22 and the slider unit 21 in sequence, and is held against the inner surface of the slider fixing cover 24. The connecting plate 22 is provided with a first clamping hole 223 through which the clamping member 25 passes and a guide hole 224 for connecting the guide member. The clamping members 25 position the slider unit 21, the connecting plate 22, and the slider fixing cover 24 in both the horizontal and vertical directions.

[0038] In this embodiment, the guide component is a guide wheel 23, which includes a guide rod and a bearing. The guide rod is fixedly connected to the connecting plate 22, and the bearing is rotatably connected to the guide rod, abutting against the track assembly. The bearing rotates continuously during its contact with the track assembly to minimize friction. However, this solution is not limited to using the guide wheel 23; it can also be replaced with a guide friction plate.

[0039] In this embodiment, the track assembly includes a track rod 11 and a track support 12. The track support 12 is connected to the frame 2, and the track rod 11 is supported on the track support 12. The track rod 11 is made of a magnetically conductive material or a magnetic material. In a single-track door / window, the track rod 11 consists of one piece, and the track support 12 is inverted T-shaped to support the track rod 11. Load-bearing sliders 20 are located on both sides of the track rod 11. In a double-track door / window, the track rod 11 consists of two pieces, and the track support 12 is U-shaped to support both track rods 11. Load-bearing sliders 20 are inserted between the two track rods 11; or the load-bearing sliders 20 consist of three sets, two sets are respectively located on both sides of the two track rods 11, and one set is inserted between the two track rods 11.
