Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a magnetic load-bearing device and a door / window. Background Technology
[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

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0026] 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.
[0027] See Figure 1-4 This embodiment provides a door and 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 realize the magnetic levitation connection between the frame 2 and the sash 3.
[0028] The magnetic load-bearing device 1 in this solution can be applied to single-track or double-track doors and windows.
[0029] Specifically, the magnetic load-bearing device 1 includes a load-bearing slider 20 and a track assembly 10, which are integrated magnetic levitation connection structures. The load-bearing slider 20 is provided with a second docking part 242, which is used to connect with the first docking part 31 on the fan body 3. The track assembly 10 is provided with a fourth docking part 121, which is used to connect with the third docking part 201 on the frame 2. By designing the load-bearing slider 20 and the track assembly 10 as an integrated magnetic levitation connection structure, the load-bearing slider 20 and the track assembly 10 are connected together in advance, and then connected to the third docking part 201 of the frame 2 through the fourth docking part 121, and the second docking part 242 is connected to the first docking part 31 of the frame 2. This facilitates the assembly between the load-bearing slider 20 and the track assembly 10, simplifies the steps of installing the integrated magnetic levitation connection structure onto the frame 2 and the fan body 3, and saves time and costs.
[0030] In this embodiment, the load-bearing slider 20 includes several slider units 21 and several connecting plates 22 connected in series with the slider units 21. All slider units 21 and connecting plates 22 are enclosed within a slider fixing cover 24. The connecting plates 22 are connected to guide wheels 23. The slider units 21 attract each other to the track assembly 10, and the guide wheels 23 abut against the track assembly 10 to prevent contact between the slider units 21 and the track assembly 10, thus creating magnetic levitation between the slider units 21 and the track assembly 10. This design places the guide on the connecting plate 22, allowing two adjacent slider units 21 to share a single guide, thereby reducing the use of guides and saving costs.
[0031] In this embodiment, the track assembly 10 includes a track rod 11, a track support 12, and a track plug 13. The track rod 11 is used to attract the slider unit 21. The track support 12 is used to connect the track rod 11. The track plug 13 is connected to the track support 12 and is used to restrict the guide from sliding out of the track rod 11.
[0032] In a single-track door or window, the track rod 11 comprises one track, and the track support member 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 or window, the track rod 11 comprises two track rods, and the track support member 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 comprise three sets, two sets located on both sides of the two track rods 11, and one set inserted between the two track rods 11.
[0033] Specifically, this embodiment is used for double-track doors and windows. The track rods 11 include two rods, and a guide groove is formed in the track support member 12 between the two track rods 11. The guide member slides in the guide groove, and the track plugs 13 are connected to both ends of the guide groove to prevent the guide member from sliding out of the guide groove. During assembly, the load-bearing slider 20 is first slid into the track support member 12, and then the track plugs 13 are used to seal both sides of the guide groove, thereby ensuring that the load-bearing slider 20 cannot slide out, so that the load-bearing slider 20 and the track assembly 10 form an integrated magnetic levitation structure.
[0034] In this embodiment, the first docking portion 31 is an elongated groove, and the second docking portion 242 is an elongated protrusion. The elongated protrusion is used to snap and fix itself into the elongated groove. The first docking portion 31 is an elongated groove, and the second docking portion 242 is an elongated protrusion, which is used to snap into the elongated groove. It is understood that the length, width, and height of the elongated protrusion are adapted to the elongated groove to ensure that the elongated protrusion of the second docking portion 242 can be directly placed into the elongated groove for positioning.
[0035] In this embodiment, the track assembly 10 further includes a track fastener 14. The fourth docking portion 121 is provided with a fastening hole, and the track fastener 14 is used to pass through the fourth docking portion 121 and connect to the third docking portion 201. It should be noted that connecting the fourth docking portion 121 to the third docking portion 201 through the track fastener 14 can better ensure the connection stability between the frame 2 and the integrated magnetic levitation structure.
[0036] In this embodiment, the fourth docking part 121 is provided with a first step 1211, which is used to dock with the second step 2011 on the third docking part 201 to position the track assembly 10. The first step 1211 and the second step 2011 are mainly provided to facilitate the insertion of the integrated magnetic levitation structure and to facilitate accurate and rapid installation.
[0037] In this embodiment, the load-bearing slider 20 also includes a slider fixing cover 24, and a second docking part 242 is disposed on the slider fixing cover 24. The slider fixing cover 24 is used to fix the slider unit 21.
[0038] In this embodiment, the slider fixing cover 24 further includes end caps 243, which are connected to both ends of the slider fixing cover. One end of the end cap 243 is inserted into the track assembly 10, and the other ends of the two end caps 243 are used to abut against both ends of the first docking portion 31 of the fan body 3, respectively. It can be understood that the other end of the end cap 243 protrudes from the slider fixing cover 24, so that when the second docking portion 242 is inserted into the first docking portion 31, the end caps 243 on both sides can abut against the sides of the fan body 3 at both ends of the first docking portion 31, thereby achieving precise positioning and preventing the load-bearing slider 20 from moving relative to the fan body 3 in the horizontal direction.
[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
