[0028] 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.
[0029] See Figures 1-6This embodiment discloses a door and window, including a frame 2, a sash 3, and a height-adjustable magnetic load-bearing device 1. The height-adjustable magnetic load-bearing device 1 is located between the frame 2 and the sash 3 to achieve magnetic levitation connection between the frame 2 and the sash 3, which can ensure that the load-bearing slider 20 slides without friction, thereby reducing noise and facilitating pushing and pulling.
[0030] Specifically, the track structure 10 is connected to the frame 2; the height-adjustable 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 a fan body connecting frame 23, a magnet assembly 22, and a guide. The magnet assembly 22 attracts the track structure 10, and the guide abuts against the track structure 10 to prevent the magnet assembly 22 from contacting the track structure 10 to form magnetic levitation. The fan body connecting frame 23 is connected to the fan body 3, and the guide is connected to the fan body connecting frame 23. The magnet assembly 22 is vertically and vertically connected to the fan body connecting frame 23 to adjust the magnetic attraction between the magnet assembly 22 and the track structure 10.
[0031] By connecting the magnet assembly 22 to the fan body connecting frame 23 in a height-adjustable manner, it is convenient to adjust the relative position between the magnet assembly 22 and the track after the fan body 3 is installed into the frame 2, so as to adjust the magnetic attraction between the magnet assembly 22 and the track.
[0032] The track structure 10 includes a track rod 11 and a track support 12. The track rod 11 is made of magnetic or magnetically conductive material, and the track support 12 is connected to the frame 2, with the track rod 11 supported on the track support 12. The track rod 11 can be square or round, and the shape of the track support 12 can be adjusted to suit the shape of the track rod 11. For ease of installation, the track rod 11 and the track support 12 can also be designed as a single integral structure.
[0033] It should be noted that the magnetic suction load-bearing device in this solution is divided into a single-track magnetic suction load-bearing device and a double-track magnetic suction load-bearing device.
[0034] The track support 12 in the monorail magnetic load-bearing device is T-shaped, with a track rod 11 in the middle. The load-bearing slider 20 includes two sets of magnet assemblies 22 and two sets of guide members. The two sets of magnet assemblies 22 are respectively located on both sides of the track rod 11, and the two sets of guide members abut against both sides of the track rod 11.
[0035] In the dual-track magnetic load-bearing device, the track support 12 is a U-shaped support, with two track rods 11 respectively located on both sides of the track support 12. The magnet assembly 22 is inserted between the two track rods 11, and a guide member is located in the middle of the magnet assembly 22 to abut against the track rod 11; or, at least two guide members are respectively located at both ends of the magnet assembly 22 to abut against the track rod 11. This embodiment uses a dual-track magnetic load-bearing device as an example for detailed explanation.
[0036] In this embodiment, the fan body connecting frame 23 is provided with an inclined slide groove 231, and the magnet assembly 22 is provided with a horizontal slide groove 2241, a sliding column 21, and an adjusting member 24. The sliding column 21 passes through the inclined slide groove 231 and the horizontal slide groove 2241, and the adjusting member 24 is used to apply a force to the sliding column 21, so that when the sliding column 21 slides in the horizontal slide groove 2241 and the inclined slide groove 231, it drives the magnet assembly 22 to rise or fall.
[0037] In this embodiment, the magnet assembly 22 includes an adjustment bracket 224, a magnet component, and a protective shell 225. A horizontal slide groove 2241 is provided on the adjustment bracket 224, the magnet component is located inside the adjustment bracket 224, and the protective shell 225 surrounds the adjustment bracket 224 for positioning the magnet component. It is understood that the adjustment bracket 224 has an adjustment hole, and an adjustment component 24 is inserted into the adjustment hole and abuts against the sliding column 21. The adjustment component 24 is an adjustment screw. When the adjustment screw is rotated, the sliding column 21 moves horizontally and drives the fan-shaped connecting frame 23, where the inclined slide groove 231 is located, to move up and down.
[0038] In this embodiment, the magnetic component includes a first magnet 221, a second magnet 222, and a magnetic conductor 223, with the magnetic conductor 223 disposed between the first magnet 221 and the second magnet 222. The south pole of the first magnet 221 and the south pole of the second magnet 222 are aligned, as are the north poles of the first magnet 221 and the second magnet 222. It is understood that the combination of the first magnet 221 and the second magnet 222 can better enhance the magnetism. Specifically, the magnetic conductor 223 is disposed between the first magnet 221 and the second magnet 222 along the magnetic field direction of the first magnet 221 and the second magnet 222.
[0039] In this embodiment, the length of the magnetic conductor 223 is greater than or equal to the length of the first magnet 221 and the length of the second magnet 222, so as to ensure that the magnetic conductor 223 can comprehensively enhance the magnetic field. In a specific implementation, the lengths of the magnetic conductor 223, the first magnet 221, and the second magnet 222 are the same.
[0040] The thickness of the magnetic conductor 223 is less than or equal to the thickness of the first magnet 221 and the thickness of the second magnet 222. The magnetic conduction effect is best when the thickness of the first magnet 221 is the same as the thickness of the second magnet 222 and is twice the thickness of the magnetic conductor 223.
[0041] The height of the magnetic conductor 223 is greater than or equal to the height of the first magnet 221 and the height of the second magnet 222, wherein the height of the magnetic conductor 223 being equal to the height of the first magnet 221 and the height of the second magnet 222 saves the most material.
[0042] In this embodiment, the load-bearing slider 20 also includes an overload friction plate 26, which is connected to the other side of the fan body connecting frame 23 and is used to contact the track structure 10 under extreme conditions to avoid the fan body connecting frame 23 from contacting the track structure 10.
[0043] The guide friction plate 25 and the overload friction plate 26 are integrally formed. The overload friction plate 26 and the guide friction plate 25 are integrally formed, and the whole is L-shaped. The horizontal part is located at the bottom of the fan body connecting frame 23, and the vertical part is located on the side wall of the magnet assembly 22. This can ensure that the track rod 11 will not come into contact with the fan body connecting frame 23 and the magnet assembly 22 at the same time. The manufacturing cost is low and the installation is simple.
[0044] In another embodiment, the overload friction plate 26 can be replaced by an overload load-bearing wheel, which protrudes from the other side of the fan body connecting frame 23 and is used to contact the track structure 10 under extreme conditions to prevent the fan body connecting frame 23 from contacting the track structure 10. Under normal circumstances, the magnetism of the magnet assembly 22 matches the mass of the fan body 3, and the overload load-bearing wheel is not used. It is only necessary to use the overload load-bearing wheel under special extreme conditions.
[0045] 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.
