[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0031] See Figures 1 to 4As shown, an ultra-thin non-magnetic shaft hinge is installed between a door panel aluminum frame 1 and a cabinet side panel 2. It includes a door panel fixing seat 3, a support seat 4, a base 5, a support frame 6, a bottom plate 7, a damping structure 8, a rotating shaft 9, and a thrust spring 10. In this embodiment, the door panel aluminum frame is provided with an installation clearance groove, which is a conventional operation in the prior art. The cabinet side panel does not need to have an installation groove, thus ensuring the integrity of the cabinet side panel. During assembly, the door panel fixing seat is fixed to the door panel aluminum frame. A shaft hole 11 is provided on each of the symmetrical sidewalls at one end of the support seat, and a thrust hole 12 is provided on the support seat that is perpendicular to and connected to the shaft hole.

[0032] In practical applications, the rotating shaft is a semi-circular shaft. The shaft is housed within the shaft hole via a bushing 13. The outer end of the shaft is rotatably connected to the door panel fixing seat. The thrust spring is located within the thrust hole, and its end is abutted against the plane of the semi-circular shaft via a pusher 14. Closing is achieved by the thrust spring pushing the semi-circular shaft.

[0033] Meanwhile, in this embodiment, the base plate and damping structure are disposed within the base, with the damping structure located at the edge of the base plate. This structure reduces the thickness of the assembled base plate and damping structure. Furthermore, the damping structure's location at the edge of the base plate, compared to the traditional damping structure located at the hinge head, ensures cushioning while reducing collision noise and minimizing damage to the damper support core, thus extending its service life. During use, when the cabinet side panel is closed to 30-40 degrees, the damping structure is pushed to generate cushioning, preventing the damper from falling off and further extending its service life. During connection, the support frame is connected between the surface of the base plate and the support base, and the base is attached to and fixed to the cabinet side panel.

[0034] In practical applications, a threaded plug 15 is fixed at the opening of the thrust hole, and the outer end of the thrust spring abuts against the threaded plug. The threaded plug ensures the position of the thrust spring and provides it with sufficient elasticity.

[0035] In this embodiment, the support frame includes a vertical horizontal panel 61 and a vertical panel 62. The horizontal panel refers to a surface parallel to the side panel of the cabinet. During assembly, the horizontal panel is placed on the surface of the base plate, and the vertical panel is located on the side of the cabinet side panel. The support base is mounted on the vertical panel via screws. This structure reduces the assembly height, avoids the need to create mounting slots on the cabinet side panel, and improves the convenience and efficiency of assembly.

[0036] Meanwhile, to facilitate installation and adjustment, the support base is provided with an oblong groove, through which the screw passes and is threaded onto the vertical panel. The installation position of the support base on the vertical panel can be adjusted as needed, thus expanding its applicability.

[0037] In this embodiment, a cover position adjustment core seat 16 is provided inside the support base, and a cover position adjustment screw 17 passing through the support base and the cover position adjustment core seat is also provided; an adjustment hole is provided on the vertical panel, and a protruding post is integrally formed at the end of the cover position adjustment core seat, with the protruding post located within the adjustment hole. With the above structure, the position can be adjusted as needed to meet assembly requirements in different situations.

[0038] In this embodiment, the damping structure includes a damping adjustment plate 81, several dampers 82, and damping push seats 83 in a number matching the number of dampers. In practical applications, there can be one or two dampers. In this embodiment, there are two dampers, located at the symmetrical edges of the base plate. During assembly, the damping adjustment plate is positioned on the side of the base plate away from the door panel fixing seat and fixed to the base by damping adjustment screws 84. The dampers are located at the end edges of the damping adjustment plate, and the damping push seats are positioned on the dampers, with the end of the damping push seats protruding from the edge of the base and abutting against the side of the door panel aluminum frame. The damping adjustment screws can adjust the closing buffer intervention, specifically a self-adjusting closing buffer intervention from 60 to 20 degrees, improving the user's or cabinet side panel's different sizes and increasing its applicability.

[0039] In this embodiment, the horizontal panel is provided with several adjustment slots with different orientations; each adjustment slot contains a door back seam adjustment screw 18, an up / down adjustment screw 19, and a locking screw 20 that pass through the base plate and are threaded to the base. A dust cover 21 is snapped onto the base. This allows for locking and adjustment operations, meeting assembly requirements in different situations, expanding its applicability, and improving the convenience and reliability of assembly and disassembly.

[0040] This utility model has the following positive effects: The structure of this utility model is reasonably designed. Its base plate and damping structure are set inside the base, and the damping structure is located at the edge of the base plate, which can reduce the thickness of the overall structure. Therefore, when assembling with the cabinet side panel, it is not necessary to open the mounting slot on the cabinet side panel, which is conducive to improving the convenience and effectiveness of installation, and will not affect the integrity of the cabinet side panel. At the same time, it adopts a semi-circular shaft in conjunction with a thrust spring, which can use the thrust spring to push the semi-circular shaft to achieve a closing operation, reducing the use of strong magnets and improving the stability and reliability of use.

[0041] The support frame includes vertical horizontal panels and vertical panels. During assembly, the horizontal panels are placed on the surface of the base plate, and the vertical panels are placed on the side of the cabinet side panel. This helps to reduce the thickness of the overall structure, avoids the operation of opening mounting slots on the cabinet side panel, and improves the ease of installation.

[0042] The support base is provided with a waist-shaped groove, through which the screw passes and is threaded to the vertical panel. The support base is also provided with a cover position adjustment core seat and a cover position adjustment screw that passes through the support base and the cover position adjustment core seat. It can be adjusted as needed to meet the assembly and use requirements of different situations and improve its applicability.

[0043] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
