Description

Technical Field

[0001] This application relates to the field of hinge technology, and more particularly to a hinge and cabinet. Background Technology

[0002] Hinges, as components that connect and support two relatively rotating parts, are widely used in many fields such as furniture manufacturing, building doors and windows, and machinery equipment. However, hinges currently used on the market have limitations in load-bearing capacity, making them prone to deformation and loosening, which in turn affects the stability and safety of the overall structure. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a hinge and a cabinet, wherein the hinge has good load-bearing capacity and the cabinet has superior structural stability.

[0004] This application provides a hinge for connecting a first component and a second component, such that the first component is rotatable relative to the second component. The hinge includes a first mounting member, a pivot, a second mounting member, and a bushing. The first mounting member is fixed to the first component. The pivot includes a connecting portion and a pivot portion, the connecting portion being fixed to the first mounting member. The second mounting member is fixed to the second component. The bushing is fixed to the second mounting member and sleeves the pivot portion of the pivot. The pivot portion is rotatable relative to the bushing, such that the first mounting member is rotatable relative to the second mounting member, and thus the first component is rotatable relative to the second component.

[0005] The hinge provided in this application, by having the pivot shaft sleeved within the bushing, supports the pivot shaft and reduces friction during rotation, thereby enhancing the stability of the pivot shaft under load. Furthermore, the fixed connection between the first mounting member and the pivot shaft, and the fixed connection between the second mounting member and the bushing, together form a rotational support structure with high stability and strong support strength. This improves the load-bearing capacity of the hinge.

[0006] A second aspect of this application provides a cabinet, the cabinet including a cabinet body, a door body, and the hinge described in the first aspect, wherein one of the cabinet body and the door body is the first component, and the other of the cabinet body and the door body is the second component, and the hinge is used to enable the door body to rotate relative to the cabinet body.

[0007] In the cabinet provided in this application, since the cabinet body and the door are connected by the hinge with good load-bearing capacity, the connection between the cabinet body and the door is relatively stable, thereby the structure of the cabinet has better stability.

[0034] This application provides a hinge for connecting a first component and a second component, such that the first component is rotatable relative to the second component.

[0035] Please see Figures 1 to 7 , Figure 1 This is a structural diagram of the hinge 100 in some embodiments of this application. Figure 2 for Figure 1 An exploded view of hinge 100 is shown. Figure 3 This is a top view of hinge 100. Figure 4 This is a schematic diagram of the first side structure of hinge 100. Figure 5 This is a schematic diagram of the second side structure of hinge 100. Figure 6 This is a schematic diagram of the connection between the pivot 20 of the hinge 100 and the first mounting member 10 from one viewpoint. Figure 7 This is a schematic diagram of the connection between the rotating shaft 20 and the first mounting member 10 from another perspective. (See diagram below.) Figures 1 to 5As shown, the hinge 100 includes a first mounting member 10, a pivot 20, a bushing 30, and a second mounting member 40. The first mounting member 10 is used to fix it to the first component. Figures 1 to 7 As shown, the rotating shaft 20 includes a connecting portion 21 and a rotating shaft portion 22, with the connecting portion 21 fixed to the first mounting member. The second mounting member 40 is used to fix it to the second component, and the bushing 30 is fixed to the second mounting member 40 and sleeves the rotating shaft portion 22 of the rotating shaft 20. The rotating shaft portion 22 is rotatable relative to the bushing 30, allowing the first mounting member 10 to rotate relative to the second mounting member 40, and thus allowing the first component to rotate relative to the second component.

[0036] The hinge 100 provided in this embodiment of the application, by setting the rotating shaft to be sleeved within the bushing, allows the bushing to support the rotating shaft and reduce friction during rotation, thereby enhancing the stability of the rotating shaft under load. Furthermore, the fixed connection between the first mounting member and the rotating shaft, and the fixed connection between the second mounting member and the bushing, together form a rotational support structure with high stability and high support strength. Thus, the load-bearing capacity of the hinge is improved.

[0037] The materials of the first component and the second component can be stone, wood, or other types of materials, such as plastic, glass, ceramics, etc.

[0038] Please see Figures 6 to 8 , Figure 8 This is a side view of the bushing 30. In some embodiments, such as Figure 6 and Figure 7 As shown, the peripheral surface of the rotating shaft 22 is a stepped surface 221. Figure 8 As shown, the bushing 30 includes a pivot hole extending along the axis of the bushing 30. The pivot hole is a stepped hole 31, and at least one end of the stepped hole 31 has an opening 311. The pivot portion 22 is inserted into the stepped hole 31 and sleeved within the bushing 30. The stepped surface 221 contacts the hole wall of the stepped hole 31, and the pivot portion 22 is rotatable relative to the stepped hole 31.

[0039] When the stepped surface 221 contacts the wall of the stepped hole 31, the stepped surface 221 and the wall of the stepped hole 31 can be tightly fitted together or have a small gap.

[0040] In some embodiments, the shape of the stepped surface 221 is adapted to the shape of the hole wall of the stepped hole 31, so that when the rotating shaft 22 is inserted into the stepped hole 31, the stepped surface 221 can make relatively close and fitting contact with the hole wall of the stepped hole 31.

[0041] In some embodiments, the stepped hole 31 has an opening 311 at one end near the connecting portion 21, and no opening 311 at the other end away from the connecting portion 21. That is, the stepped hole 31 has an opening 311 at one end near the connecting portion 21 and no opening 311 at the other end along the axial direction of the bushing 30. In other embodiments, the stepped hole 31 has an opening 311 at both ends along the axial direction of the bushing 30.

[0042] The rotating shaft 22 can rotate at an angle of 360° relative to the bushing 30. The rotation angle of the first component relative to the second component can be 360° or less, such as 110° or 300°. The rotation angle of the first component relative to the second component can be made less than 360° by adjusting the relative position and structure of the two components.

[0043] By setting the peripheral surface of the rotating shaft 22 as the stepped surface 221 and providing the bushing 30 with a stepped hole 31, the limiting effect of the bushing 30 on the rotating shaft 22 can be enhanced, preventing the rotating shaft 22 from shaking in the stepped hole 31. Furthermore, the axial movement of the rotating shaft 22 can be restricted, thereby enhancing structural stability.

[0044] In some embodiments, such as Figure 2 , Figures 4 to 7 As shown, the rotating shaft portion 22 includes a first shaft portion 222 and a second shaft portion 223. The first shaft portion 222 includes a first end 2221 and a second end 2222 along the axial direction of the first shaft portion 222. The first end 2221 of the first shaft portion 222 is fixedly connected to the connecting portion 21. The second end 2222 of the first shaft portion 222 is connected to the second shaft portion 223. The projection of the second shaft portion 223 along its axial direction is located within the region where the second end 2222 is located. Figure 6 and Figure 7 As shown, the non-shaft connection area 2222a of the second shaft portion 223 and the end face of the second end 2222, which is not connected to the second shaft portion 223, forms the stepped surface 221 with the outer peripheral surface of the first shaft portion 222.

[0045] The first shaft portion 222 and the connecting portion 21 can be integrally formed, or they can be fixedly connected by means of screwing, riveting, snap-fitting, welding, etc. The first shaft portion 222 and the second shaft portion 223 can be integrally formed, or they can be fixedly connected by means of screwing, riveting, snap-fitting, welding, etc.

[0046] The central axes of the connecting part 21, the first shaft part 222 and the second shaft part 223 may coincide or be misaligned.

[0047] In some embodiments, such as Figure 8 As shown, the stepped hole 31 includes a first hole portion 312 and a second hole portion 313 that are connected. The first hole portion 312 is closer to the connecting portion 21 than the second hole portion 313, and the diameter of the first hole portion 312 is larger than that of the second hole portion 313. The projection of the second hole portion 313 along the axial direction of the bushing 30 falls within the region where the first hole portion 312 is located. The end of the first hole portion 312 away from the second hole portion 313 is provided with the opening 311, and the end of the second hole portion 313 away from the first hole portion 312 may or may not have the opening 311.

[0048] like Figure 4 and Figure 5 As shown, when the rotating shaft portion 22 is sleeved within the bushing 30, the second shaft portion 223 is located within the second hole portion 313, and the first shaft portion 222 is located within the first hole portion 312. The outer peripheral surface of the second shaft portion 223 contacts the hole wall of the second hole portion 313, and the non-shaft connection area 2222a of the second end 2222 and the outer peripheral surface of the first shaft portion 222 contact the hole wall of the first hole portion 312. The second shaft portion 223 is rotatable relative to the second hole portion 313, and the first shaft portion 222 is rotatable relative to the first hole portion 312.

[0049] As mentioned above, when the outer peripheral surface of the second shaft portion 223 contacts the hole wall of the second hole portion 313, it can be in close contact or have a slight gap. Similarly, when the non-shaft connection area 2222a of the second end 2222 and the outer peripheral surface of the first shaft portion 222 contact the hole wall of the first hole portion 312, they can be in close contact or have a slight gap.

[0050] In some embodiments, the first shaft portion 222 and the second shaft portion 223 may be cylindrical, with the cross-sectional diameter of the second shaft portion 223 being smaller than that of the first shaft portion 222, and the first hole portion 312 and the second hole portion 313 being cylindrical holes. In other embodiments, the first shaft portion 222 and the second shaft portion 223 may be other shapes, such as tapered columns, and the first hole portion 312 and the second hole portion 313 may be tapered holes.

[0051] By providing the rotating shaft 22 with a stepped first shaft 222 and a stepped second shaft 223, and the stepped hole 31 with a stepped first hole 312 and a stepped second hole 313, it is possible not only to prevent the rotating shaft 22 from shaking or moving axially within the bushing 30, but also to simplify the manufacturing process and improve production efficiency.

[0052] In other embodiments, the rotating shaft portion 22 may include at least three shaft portions connected sequentially along the axial direction of the rotating shaft portion 22. The radial dimensions of the at least three shaft portions gradually decrease in the direction away from the connecting portion 21. The stepped hole 31 may include at least three interconnected holes arranged sequentially along the axial direction of the bushing 30. The diameters of the at least three holes gradually decrease in the direction away from the connecting portion 21. The radial dimensions of each shaft portion at all positions may be the same, and the diameters of each hole portion at all positions may be the same. The radial dimension is the dimension in the direction perpendicular to the axial direction of the rotating shaft portion 22.

[0053] In some other embodiments, the radial dimension of the rotating shaft portion 22 gradually decreases in the direction away from the connecting portion 21, that is, the radial dimension of the rotating shaft portion 22 at each position gradually decreases in the direction away from the connecting portion 21. Similarly, the diameter of the rotating shaft hole gradually decreases in the direction away from the connecting portion 21, that is, the diameter of the rotating shaft hole at each position gradually decreases in the direction away from the connecting portion 21.

[0054] In some other embodiments, the radial dimensions of the rotating shaft portion 22 are the same at all locations, and the diameter of the rotating shaft hole is the same at all locations.

[0055] In some embodiments, the connecting portion 21, the first shaft portion 222, and the second shaft portion 223 may be made of a metallic material, such as stainless steel, copper, or other metallic materials, which can increase the support capacity of the rotating shaft 22. The bushing 30 may be made of a metallic material, such as copper, or other metallic materials. Using copper to make the bushing 30 can reduce the friction between the bushing 30 and the rotating shaft portion 22 during rotation.

[0056] In other embodiments, the connecting portion 21, the first shaft portion 222, the second shaft portion 223, and the bushing 30 may be made of other materials, such as plastic, ceramic, etc.

[0057] In some embodiments, the radial dimension of the first shaft portion 222 can be 4mm-6mm, for example 5mm. Obviously, this radial dimension can also be less than 4mm or greater than 6mm. The radial dimension of the second shaft portion 223 can be 2mm-4mm, for example 3mm. Obviously, this radial dimension can also be less than 2mm or greater than 4mm. The radial dimension of the connecting portion 21 can be 3mm-6mm, for example 4.4mm. Obviously, this radial dimension can also be less than 3mm or greater than 6mm.

[0058] In some embodiments, the axial dimension of the first shaft portion 222 can be 8mm-14mm, for example 11mm. Obviously, this axial dimension can also be less than 8mm or greater than 14mm. The axial dimension of the second shaft portion 223 can be 2mm-3mm, for example 2.5mm. Obviously, this axial dimension can also be less than 2mm or greater than 3mm. The axial dimension of the connecting portion 21 can be 2mm-3mm, for example 2.5mm. Obviously, this axial dimension can also be less than 2mm or greater than 3mm.

[0059] In some embodiments, the diameter of the first hole 312 is 4mm-6mm, for example, 5mm, and the diameter of the second hole 313 is 2mm-4mm, for example, 3mm. Obviously, the diameter of the first hole 312 can also be less than 4mm or greater than 6mm, and the diameter of the second hole 313 can also be less than 2mm or greater than 4mm.

[0060] In some embodiments, the axial dimension of the first hole 312 is 7mm-11mm, for example, 9mm, and the axial dimension of the second hole 313 is 1mm-3mm, for example, 2mm. Obviously, the axial dimension of the first hole 312 can also be less than 7mm or greater than 11mm, and the axial dimension of the second hole 313 can also be less than 1mm or greater than 3mm.

[0061] In some embodiments, the radial dimension of the bushing 30 can be 6mm-10mm, for example, the radial dimension of the bushing 30 can be 8mm. The axial dimension of the bushing 30 can be 11mm-17mm, for example, the axial dimension of the bushing 30 can be 14mm. Obviously, the radial dimension of the bushing 30 can also be less than 6mm or greater than 10mm, and the axial dimension can also be less than 11mm or greater than 17mm.

[0062] In some embodiments, such as Figure 8As shown, the second hole 313 is a blind hole, and the end of the second hole 313 away from the first hole 312 is a closed end wall 3121. The second shaft 223 is located inside the second hole 313, and the end of the second shaft 223 away from the first shaft 222 contacts the end wall 3121 of the second hole 313 away from the first hole 312. By setting the end of the second shaft 223 away from the first shaft 222 to contact the end wall 3121, the rotating shaft 22 can be further limited, thereby further preventing the rotating shaft 22 from shaking.

[0063] In some other embodiments, the second hole 313 may be a through hole, which extends through the end of the bushing 30 away from the connecting portion 21.

[0064] In some embodiments, the distance between the end wall 3121 of the second hole 313 and the end face of the bushing 30 away from the connecting portion 21 is 0.5mm-1.5mm, for example, 1mm. Obviously, this distance can also be less than 0.5mm or greater than 1.5mm.

[0065] Please see Figure 2 , Figure 4 , Figure 9 as well as Figure 10 , Figure 9 This is a top view of the second mounting component 40 in some embodiments of this application. Figure 10 This is a side view of the second mounting member 40 in some embodiments of this application. In some embodiments, such as Figure 2 , Figure 4 , Figure 9 as well as Figure 10 As shown, the second mounting member 40 has a first mounting hole 41. Figure 2 and Figure 4 As shown, the bushing 30 is inserted into the first mounting hole 41 and is fixedly connected to the second mounting member 40.

[0066] By opening the first mounting hole 41 in the second mounting member 40 and inserting the bushing 30 into the first mounting hole 41, the assembly process of the bushing 30 and the second mounting member 40 can be simplified, making the assembly process simpler and faster. Furthermore, it can save the space occupied by the bushing 30.

[0067] In some embodiments, the bushing 30 and the second mounting member 40 may be welded together to further secure the bushing 30 and the second mounting member 40.

[0068] In some embodiments, the second mounting member 40 may be made of a metallic material, such as aluminum alloy, or other metallic materials, to increase its support capacity. In other embodiments, the second mounting member 40 may be made of other materials, such as plastic, ceramic, etc.

[0069] In some embodiments, the second mounting member 40 may be plate-shaped, with a length of 60mm-100mm, for example 80mm, and a width of 40mm-60mm, for example 50mm. Obviously, the length of the second mounting member 40 may also be less than 60mm or greater than 100mm, and the width may also be less than 40mm or greater than 60mm.

[0070] The depth of the first mounting hole 41 can be 12mm-18mm, for example, 15mm. Obviously, the depth can also be less than 12mm or greater than 18mm.

[0071] In some embodiments, such as Figure 3 and Figure 9 As shown, the second mounting member 40 may include a protrusion 45 and a main body 46 connected to each other. The main body 46 includes a first surface 461 and a second surface 462 facing each other. The protrusion 45 extends from the first surface 461 of the main body 46 in a direction away from the second surface 462. The first mounting hole 41 may be formed in the portion of the main body 46 near the protrusion 45 and in the portion of the protrusion 45 near the main body 46. The first surface 461 is used to fit against the second member, and the first surface 461 may be planar.

[0072] By providing the protrusion 45, the second mounting member 40 not only has sufficient space to open the first mounting hole 41, but also reduces the thickness of the main body 46, making the second mounting member 40 lighter and smaller.

[0073] The thickness of the main body 46 is the distance between the first surface and the second surface.

[0074] In some embodiments, the central axis of the first mounting hole 41 may be located on the second surface 462, so that half of the first mounting hole 41 is opened in the main body portion 46 and the other half is opened in the protrusion portion 45, which is beneficial to the structural stability of the second mounting member 40.

[0075] In some embodiments, the thickness of the main body 46 may be 7mm-11mm, for example 9mm. Obviously, the thickness may also be less than 7mm or greater than 11mm.

[0076] In some embodiments, the distance between the end of the protrusion 45 away from the first surface 461 and the first surface 461 can be 12mm-20mm, for example 15.95mm. Obviously, this distance can also be less than 12mm or greater than 20mm.

[0077] In some embodiments, such as Figure 4 and Figure 5 As shown, the bushing 30 includes a cylindrical part 32 and a flange part 33 connected to each other. The flange part 33 is circumferentially disposed at one end of the cylindrical part 32 along the axial direction of the cylindrical part 32. The cylindrical part 32 is inserted into the first mounting hole 41, and the flange part 33 abuts against the edge of the first mounting hole 41.

[0078] By setting the flange portion 33 to abut against the edge of the first mounting hole 41, the axial movement of the bushing 30 can be restricted. Furthermore, the flange portion 33 makes it easier to position the bushing 30 during installation. That is, the contact between the flange portion 33 and the edge of the first mounting hole 41 ensures that the bushing 30 is installed in the correct position, simplifying the installation process. In addition, when the bushing 30 is subjected to external loads, the flange portion 33 can disperse the stress, which helps to reduce stress concentration and extend the service life of the bushing 30.

[0079] Furthermore, the flange 33 is located on the side of the second mounting member 40 closest to the first mounting member 10, meaning that the flange 33 exists between the second mounting member 40 and the first mounting member 10. This creates a gap, or door gap, between the first component connected to the first mounting member 10 and the second component connected to the second mounting member 40. This prevents friction between the first and second components and helps the user distinguish the boundary between them, facilitating the opening and closing of both components. Additionally, the gap enhances aesthetics.

[0080] In some embodiments, the stepped hole 31 penetrates the flange portion 33 and the end of the cylindrical portion 32 closest to the flange portion 33. The end of the cylindrical portion 32 furthest from the flange portion 33 may or may not be penetrated by the stepped hole 31.

[0081] The cylindrical part 32 and the flange part 33 can be integrally formed, or they can be connected by means of screwing, riveting, snap-fitting, welding, etc.

[0082] In some embodiments, the thickness of the flange portion 33 is 1mm-3mm, for example, the thickness of the flange portion 33 is 2mm. In other embodiments, the thickness of the flange portion 33 may be other values. The thickness of the flange portion 33 may be a dimension along the axial direction of the bushing 30.

[0083] In some embodiments, the flange portion 33 has a radial dimension of 9mm-15mm, for example 12mm, along the bushing 30.

[0084] Please see Figures 11 to 13 , Figure 11 This is a side view of the bushing 30 in some other embodiments of this application. Figure 12 This is a top view of the second mounting member 40 in some other embodiments of this application. Figure 13 This is a side view of the second mounting member 40 in some other embodiments. In some embodiments, such as Figure 11 As shown, the bushing 30 further includes a positioning part 34, which is connected to the cylindrical part 32. The positioning part 34 is disposed on the outer wall of the cylindrical part 32 and extends along the axial direction of the cylindrical part 32. Figure 12 and Figure 13 As shown, the wall of the first mounting hole 41 is provided with a positioning groove 42 that is adapted to the positioning part 34, and the positioning part 34 is inserted into the positioning groove 42 and abuts against the positioning groove 42.

[0085] The bushing 30 may include one or more positioning portions 34, and the wall of the first mounting hole 41 may be provided with one or more positioning grooves 42. When the bushing 30 includes multiple positioning portions 34 and the wall of the first mounting hole 41 is provided with multiple positioning grooves 42, the multiple positioning portions 34 are radially spaced on the outer wall of the cylindrical portion 32, and the multiple positioning grooves 42 are radially spaced on the wall of the first mounting hole 41. The positioning portions 34 and the positioning grooves 42 may be cylindrical, square, or similar.

[0086] By providing the positioning part 34, the bushing 30 can be precisely positioned to a predetermined position during installation, achieving precise fixation between the bushing 30 and the first mounting hole 41. Furthermore, the positioning part 34 is connected to the positioning groove 42, which improves the connection strength between the bushing 30 and the first mounting hole 41.

[0087] In some other embodiments, the bushing 30 may not include the positioning part 34, and the first mounting hole 41 may not be provided with the positioning groove 42.

[0088] Please see Figure 14 , Figure 14This is a top view of the first mounting component 10. In some embodiments, such as... Figure 14 As shown, the first mounting member 10 has a second mounting hole 11, and the connecting part 21 is inserted into the second mounting hole 11 and fixed to the first mounting member 10, so that the first shaft part 222 is fixed to the first mounting member 10.

[0089] By opening the second mounting hole 11 in the first mounting member 10 and inserting the connecting part 21 into the second mounting hole 11, the assembly process of the connecting part 21 and the first mounting member 10 can be simplified, making the assembly process simpler and faster. Furthermore, it can save the space occupied by the connecting part 21.

[0090] In some embodiments, the connecting portion 21 and the first mounting member 10 may be welded together to further secure the connecting portion 21 and the first mounting member 10.

[0091] In some embodiments, the second mounting hole 11 penetrates the first mounting member 10 along the thickness direction of the first mounting member 10, and one end of the connecting portion 21 away from the first shaft portion 222 is exposed outside the first mounting member 10 and flush with the surface of the first mounting member 10 away from the second mounting member 40, thereby making it more aesthetically pleasing.

[0092] In some embodiments, the first mounting member 10 may be made of a metallic material, such as stainless steel or other metallic materials, to increase the support capacity of the first mounting member 10. In other embodiments, the first mounting member 10 may be made of other materials, such as plastic, ceramic, etc.

[0093] In other embodiments, the first mounting member 10 may be connected to the connecting part 21 by means of screwing, riveting, snapping, welding, etc. For example, the end of the connecting part 21 away from the rotating shaft 22 may be welded to the end of the first mounting member 10 near the rotating shaft 22.

[0094] In some other embodiments, the connecting portion 21, the first shaft portion 222 and the second shaft portion 223 may be integrally formed with the first mounting member 10.

[0095] In some embodiments, the first mounting member 10 may be plate-shaped, with a length of 40mm-60mm, for example 50mm, a width of 15mm-25mm, for example 20mm, and a thickness of 1mm-3mm, for example 2mm. Obviously, the length of the first mounting member 10 may also be less than 40mm or greater than 60mm, the width may also be less than 15mm or greater than 25mm, and the thickness may also be less than 1mm or greater than 3mm.

[0096] In some embodiments, the distance between the central axis of the connecting portion 21 and one end of the first mounting member 10 along the length direction is 7mm-11mm, for example 9mm. Obviously, this distance can also be less than 7mm or greater than 11mm.

[0097] In some embodiments, such as Figures 1 to 5 , Figure 9 , Figure 10 as well as Figure 13 As shown, the second mounting member 40 has at least one third mounting hole 43 for a bolt to pass through and lock the second mounting member 40 and the second component. In some other embodiments, the second mounting member 40 can also be fixedly connected to the second component by riveting, snap-fitting, welding, etc. The third mounting hole 43 is located on the main body 46.

[0098] In some embodiments, such as Figure 3 and Figure 14 As shown, the first mounting member 10 has at least one fourth mounting hole 12, which is used for bolts to pass through and lock the first mounting member 10 and the first component. In some other embodiments, the first mounting member 10 can also be fixedly connected to the first component by riveting, snap-fitting, welding, or other methods.

[0099] The first mounting member 10 is subjected to a force from the first component in a direction parallel to the axial direction of the rotating shaft 20 and close to the second mounting member 40. The second mounting member 40 is subjected to a force from the second component in a direction parallel to the axial direction of the bushing 30 and close to the first mounting member 10. Thus, the rotating shaft 20 and the bushing 30 are subjected to forces from the first component and the second component in opposite directions, thereby preventing the rotating shaft 20 from moving within the bushing 30 along the axial direction of the rotating shaft 20 or even slipping out of the bushing 30.

[0100] In some embodiments, the first mounting member 10 includes a first end and a second end along the length direction, the connecting portion 21 is closer to the second end than the first end, and the fourth mounting hole 12 is located between the connecting portion 21 and the first end.

[0101] In some embodiments, the sidewall of the rotating shaft hole of the bushing 30 is provided with at least one limiting groove (not shown in the figure), which extends along the axial direction of the bushing 30. The sidewall of the rotating shaft portion 22 is provided with at least one limiting rod (not shown in the figure) that cooperates with the limiting groove. One end of the limiting rod is connected to the sidewall of the rotating shaft portion 22, and the other end extends into the limiting groove. The limiting rod cooperates with the limiting groove to limit the angle of rotation of the rotating shaft portion 22 relative to the bushing 30 to be within a preset angle range. When the rotating shaft 22 rotates relative to the bushing 30, the limiting rod rotates around the central axis of the rotating shaft 22 in the circumferential direction. When the limiting rod rotates clockwise to the first limit position, the portion of the limiting rod extending into the limiting groove abuts against the first groove wall of the limiting groove. When the limiting rod rotates counterclockwise to the second limit position, the portion of the limiting rod extending into the limiting groove abuts against the second groove wall of the limiting groove. The first groove wall and the second groove wall are opposite each other. The range of the angle of rotation of the limiting rod between the first limit position and the second limit position is the preset angle range.

[0102] By limiting the rotation angle of the rotating shaft 22 relative to the bushing 30, the rotation angle of the second component relative to the first component can be limited, preventing the second component or the first component from rotating excessively, and the opening angle of the second component and the first component can be precisely controlled.

[0103] In some other embodiments, the bushing 30 may not be provided with the limiting groove, and the rotating shaft 22 may not be provided with the limiting rod.

[0104] In some embodiments, the inner surface of the sidewall of the pivot hole of the bushing 30 is provided with a first anti-detachment member (not shown in the figure), which extends circumferentially along the pivot hole. The outer surface of the sidewall of the pivot portion 22 is provided with a second anti-detachment member (not shown in the figure), which extends circumferentially along the pivot portion 22. The second anti-detachment member cooperates with the first anti-detachment member to restrict the axial movement of the pivot portion 22 within the pivot hole. The first anti-detachment member is one of a groove and a protrusion, and the second anti-detachment member is the other of a groove and a protrusion.

[0105] Wherein, when the first anti-detachment component is a groove and the second anti-detachment component is a protrusion, the groove is provided on the side wall of the rotating shaft hole along the circumference of the rotating shaft hole, and the protrusion is provided on the side wall of the rotating shaft portion 22 along the circumference of the rotating shaft portion 22. The protrusion is inserted into the groove and can slide in the groove.

[0106] When the first anti-detachment component is a protrusion and the second anti-detachment component is a groove, the protrusion is disposed on the side wall of the rotating shaft hole along the circumference of the rotating shaft hole, and the groove is disposed on the side wall of the rotating shaft portion 22 along the circumference of the rotating shaft portion 22. The protrusion is inserted into the groove and can slide within the groove.

[0107] By setting the protrusion to be embedded in the groove, the axial movement of the rotating shaft 22 relative to the bushing 30 can be further prevented, thereby improving the connection stability of the rotating shaft 22 and the bushing 30 during rotation. Furthermore, by setting the protrusion to slide within the groove, the rotating shaft 22 can rotate smoothly within the bushing 30.

[0108] In some embodiments, the groove is an open annular shape, meaning that there is a gap between the opposite ends of the groove along the circumference of the pivot hole or the circumference of the pivot portion 22, and they are not engaged. The protrusion is also an open annular shape, meaning that there is a gap between the opposite ends of the protrusion along the circumference of the pivot portion 22 or the circumference of the pivot hole, and they are not engaged. When the pivot portion 22 rotates relative to the pivot hole, the protrusion slides between the opposite ends of the groove, causing the pivot portion 22 to rotate within a preset angle range, wherein the preset angle range is the angle range corresponding to the sliding of the protrusion between the opposite ends of the groove.

[0109] By setting both the protrusion and the groove to be open annular, the angle of rotation of the rotating shaft 22 relative to the bushing 30 can be set by adjusting the curvature of the protrusion and the groove, thereby limiting the angle of rotation of the rotating shaft 22 relative to the bushing 30.

[0110] In other embodiments, both the protrusion and the groove may be closed annular, so that the rotating shaft portion 22 rotates at an angle of 360° relative to the bushing 30.

[0111] In some other embodiments, the bushing 30 may not be provided with the first anti-detachment component, and the rotating shaft portion 22 may not be provided with the second anti-detachment component.

[0112] Please see Figure 15 This is a structural schematic diagram of the cabinet 200 provided in some embodiments of this application. For example... Figure 15 As shown, the cabinet 200 includes a cabinet body 201, a door body 202, and a hinge 100 as described in any of the aforementioned embodiments. One of the cabinet body 201 and the door body 202 is the first component, and the other of the cabinet body 201 and the door body 202 is the second component. The hinge 100 is used to enable the door body 202 to rotate relative to the cabinet body 201.

[0113] In some embodiments, the first mounting member 10 is fixed to the cabinet body 201, and the second mounting member 40 is fixed to the door body 202. In other embodiments, the first mounting member 10 is fixed to the door body 202, and the second mounting member 40 is fixed to the cabinet body 201.

[0114] In some embodiments, the cabinet 200 may be a stove storage cabinet, appliance cabinet, sink cabinet, etc. Obviously, the cabinet 200 may be other types of cabinets. In other embodiments, the first component and the second component may be other types of structural components, such as structural components used in building doors and windows, or mechanical equipment.

[0115] Please see Figure 16 This is a schematic diagram of the structure of the first component 203 and the hinge 100 in some embodiments of this application. In some embodiments, such as Figure 16 As shown, the first component 203 has a communicating mounting groove 2031 and a clearance groove 2032. The mounting groove 2031 and the clearance groove 2032 can be stacked. The first mounting member 10 is inserted into the mounting groove 2031 and is fixedly connected to the first component 203. At least a portion of the rotating shaft 22 is located in the clearance groove 2032, and there is a gap between the rotating shaft 22 and the clearance groove 2032.

[0116] By providing the mounting groove 2031 in the first component 203, the first mounting member 10 can be inserted into the mounting groove 2031, achieving concealed installation of the first mounting member 10 and saving space occupied by the first mounting member 10, making the structure of the cabinet 200 more compact and the appearance more aesthetically pleasing. By providing the clearance groove 2032, clearance space can be provided for the pivot portion 22 when the first mounting member 10 is inserted into the mounting groove 2031.

[0117] Among them, such as Figure 16 As shown, the orthographic projection of the clearance groove 2032 onto the mounting groove 2031 is located within the area of ​​the mounting groove 2031, which avoids the groove opening of the clearance groove 2032 being too large and helps to improve structural stability. The cross-sections of the mounting groove 2031 and the clearance groove 2032 can be T-shaped.

[0118] In some embodiments, the dimension of the mounting groove 2031 along the arrangement direction of the mounting groove 2031 and the clearance groove 2032 may be close to the thickness of the first mounting member 10, and the thickness of the first mounting member 10 is the dimension along the axial direction of the rotating shaft 20.

[0119] In some embodiments, the dimension of the clearance groove 2032 along the stacking direction of the mounting groove 2031 and the clearance groove 2032 can be close to the length of the pivot portion 22, and the length of the pivot portion 22 is the dimension along the axial direction of the pivot shaft 20. This allows the pivot portion 22 to be hidden within the clearance groove 2032, thereby further making the structure of the cabinet 200 more compact and its appearance more aesthetically pleasing.

[0120] In some other embodiments, the first mounting member 10 may be mounted on the outer wall of the first component 203.

[0121] In some embodiments, such as Figure 15 As shown, the second mounting member 40 can be mounted on the surface of the second component facing the interior of the cabinet 200 to conceal the second mounting member 40. In some other embodiments, the second mounting member 40 may be located at other positions on the second component.

[0122] The above are the implementation methods of the embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the embodiments of this application, and these improvements and modifications are also considered to be within the protection scope of this application.
