Description

Technical Field

[0001] This application relates to the field of home furnishings, and more specifically, to a cabinet connector and a cabinet. Background Technology

[0002] Standard cup hinges are widely used in the furniture industry, such as for doors, windows, wardrobes, and cabinets. They connect cabinet doors to the cabinet body, allowing the doors to open and close within a certain angle relative to the cabinet. Also known as hinges, they are mechanical devices used to connect two fixed objects, allowing relative rotation between them. Common opening angles for standard cup hinges are 90°, 125°, 165°, and 180°. However, when furniture and cabinets use alloy-edged door panels, the alloy edge finishing process on doors with alloy edges causes the side of the door that connects to the cabinet body to bulge towards the cabinet, compared to non-alloy-edged door panels. If a standard cup hinge is installed with an alloy-edged door panel in this case, the hinge arm will jam against the edge of the alloy-edged door panel, resulting in an opening angle of less than 90°. This is insufficient for everyday use, severely impacting the user experience and the normal operation of other hardware inside the cabinet.

[0003] Chinese patent application CN210977001U, published on July 1, 2020, discloses a height-enhancing structure for furniture hinges. The structure includes a fixed base, a gasket that engages with the fixed base via a snap-fit, a detachable connecting arm fastened to the surface of the fixed base, a rocker arm assembly mounted on the connecting arm, and a hinge cup hinged to the rocker arm assembly. This structure is claimed to increase the mounting height of the furniture hinge without altering its original structure, thus avoiding the drawback of existing technologies that limit users to equipping fixed mounting brackets of various heights. However, this structure is a height-enhancing structure placed between the cabinet and the connecting arm, aiming to meet users' needs for different mounting heights of the fixed base and the furniture cabinet. It does not address how to reduce the jamming problem between the alloy-edged door panel and the cabinet. Therefore, how to improve the existing furniture hinge structure to achieve an opening angle of at least 90° relative to the cabinet for the alloy-edged door panel has become one of the urgent technical problems to be solved at present. Summary of the Invention

[0004] In view of this, this application provides a cabinet connector and a cabinet to improve the problem of hinge arm and aluminum edge panel jamming during opening and closing, which is beneficial to improving people's user experience.

[0005] In a first aspect, this application provides a cabinet connector, including a hinge assembly and a hinge cup washer.

[0006] The hinge assembly includes a hinge cup and a hinge, the hinge being rotatably connected to the hinge cup.

[0007] The hinge cup gasket includes a gasket plate and a washer, wherein the washer is fixedly connected to the gasket plate.

[0008] The pad includes an upper support plate and a lower support plate. The upper support plate is parallel to the lower support plate and is fixedly connected to the lower support plate along the thickness direction of the pad. The orthographic projection of the upper support plate in the direction perpendicular to the plane of the upper support plate is within the orthographic projection of the lower support plate in the direction perpendicular to the plane of the upper support plate.

[0009] The upper support plate includes straight edges and irregular edges arranged opposite each other along its width direction. The irregular edge includes two straight edges and an arc-shaped edge located between and connecting the two straight edges. The two straight edges are parallel to the straight edges, and the two straight edges are connected to the two ends of the straight edges through side edges. The arc-shaped edge bends toward the straight edges to form a recess. Along a direction parallel to the plane of the upper support plate, the minimum gap between the arc-shaped edge and the straight edge is greater than 0.

[0010] The upper support plate also includes a groove located between the arc-shaped edge and the straight edge. The groove includes a left vertical edge, a horizontal edge, a right vertical edge, and an arc-shaped edge. The arc-shaped edge of the groove is fixedly connected to a portion of the washer. The horizontal edge of the groove is parallel to the straight edge of the upper support plate, and the arc-shaped edge of the groove coincides with the arc-shaped edge of the upper support plate. The groove forms a recess on the upper support plate along the direction from the upper support plate to the lower support plate.

[0011] The lower support plate includes a straight edge and an irregular edge arranged opposite to each other along its width direction. The irregular edge includes two straight edges and an arc-shaped edge located between the two straight edges and connecting them. The two straight edges are parallel to the straight edges, and are connected to the two ends of the straight edges via side edges. The arc-shaped edge bends toward the straight edges to form a recess. The minimum gap between the arc-shaped edge and the straight edge is greater than 0 along a direction parallel to the plane of the lower support plate.

[0012] The recessed portion of the upper support plate and the recessed portion of the lower support plate together form a receiving groove, and the washer is located in the receiving groove;

[0013] The pad is provided with a through hole that penetrates the upper support plate and the lower support plate along the thickness direction;

[0014] The lower support plate, the upper support plate, and the washer are integrally connected.

[0015] Secondly, this application also provides a cabinet, including the cabinet connector described in the first aspect; the cabinet includes a cabinet body and a cabinet door, the cabinet door includes an alloy edge, the alloy edge wrapping around the edge of the cabinet door;

[0016] Fasteners connect the hinge assembly and the cabinet body. The fasteners pass through the through holes on the hinge cup fixing plate and the through holes on the hinge cup pad in sequence along the thickness direction of the hinge cup pad to fix the hinge to the pad and the cabinet door.

[0017] Compared with the prior art, the cabinet connector and cabinet provided in this application achieve at least the following beneficial effects:

[0018] 1. By setting a hinge cup gasket that is integrally connected to the upper support plate, lower support plate and washer, the cabinet door can be opened at an angle of not less than 90° relative to the cabinet body when using alloy edge-sealed door panels, which improves the user experience and extends the service life of the hinge assembly.

[0019] 2. The hinge cup gasket is compatible with the hinge assembly in shape, and can play a synergistic role with the hinge assembly and hinge cup gasket when installing with alloy edge-sealed door panels as cabinet doors. The installation method is simple and can be widely used in the home furnishing field.

[0020] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time.

[0032] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] Figure 1 The diagram shown illustrates the opening and closing angles of a cabinet door in the prior art, where the cabinet body and door are connected by a standard cup hinge. Figure 2 As shown Figure 1 For a magnified view of the part, please refer to... Figure 1 and Figure 2Cabinet 00' comprises cabinet body 10' and cabinet door 20'. Cabinet door 20' includes an alloy edge 21'. Cabinet door 20' is connected to cabinet body 10' via a standard cup hinge 30'. A standard cup hinge 30', also known as a hinge, is a mechanical device used to connect two fixed objects and allow relative rotation between them. Standard cup hinges 30' are widely used in the furniture industry, such as for doors, windows, wardrobes, and cabinets. The standard cup hinge 30' connects cabinet door 20' to cabinet body 10' and allows cabinet door 20' to open and close relative to cabinet body 10' within a certain angle. Compared to non-alloy edge door panels, the alloy edge finishing process used on cabinet door 20' with alloy edge 21' causes the side of cabinet door 20' that connects to cabinet body 10' to protrude towards cabinet body 10', thus causing cabinet door 20' to jam when opening. Figure 1 As shown, when the cabinet door 20' includes the alloy edge 21', if a standard cup hinge 30' is used for connection, the maximum opening angle of the cabinet door 20' is 87°, which does not reach the minimum opening angle of 90° for daily retrieval of items, seriously affecting the user experience and the normal use of other hardware inside the cabinet.

[0039] To solve the above technical problems, please refer to Figures 3-7 This application proposes a cabinet connector 12, including a hinge assembly 30 and a hinge cup washer 40. The hinge assembly 30 includes a hinge cup 32 and a hinge 31, and the hinge 31 is rotatably connected to the hinge cup 32.

[0040] The hinge cup washer 40 includes a washer plate 90 and a washer 70, with the washer 70 fixedly connected to the washer plate 90.

[0041] The pad 90 includes an upper support plate 50 and a lower support plate 60. The upper support plate 50 and the lower support plate 60 are parallel to each other and are fixedly connected along the thickness direction of the pad 90. The orthographic projection of the upper support plate 50 in the direction perpendicular to the plane of the upper support plate 50 is within the orthographic projection of the lower support plate 60 in the direction perpendicular to the plane of the upper support plate 50.

[0042] The upper support plate 50 includes a straight edge 51 and an irregular edge 57 arranged opposite to each other along its width direction. The irregular edge 57 includes two straight edges 53 and an arc-shaped edge 52 located between and connecting the two straight edges 53. The two straight edges 53 are parallel to the straight edges 51, and the two straight edges 53 are connected to the two ends of the straight edges 51 through side edges 54. The arc-shaped edge 52 bends toward the straight edges 51 to form a recess. The minimum gap 56 between the arc-shaped edge 52 and the straight edges 51 is greater than 0 along the direction parallel to the plane of the upper support plate 50.

[0043] The upper support plate 50 also includes a groove 80, which is located between the arc-shaped edge 52 and the straight edge 51. The groove 80 includes a left vertical edge 81, a horizontal edge 82, a right vertical edge 83, and an arc-shaped edge 84. The arc-shaped edge 84 is fixedly connected to a portion of the washer 70. The horizontal edge 82 of the groove 80 is parallel to the straight edge 51 of the upper support plate 50, and the arc-shaped edge 84 coincides with the arc-shaped edge 52 of the upper support plate 50. The groove 80 forms a recess on the upper support plate 50 in the direction from the upper support plate 50 to the lower support plate 60.

[0044] The lower support plate 60 includes a straight edge 61 and an irregular edge 67 arranged opposite to each other along its width direction. The irregular edge 67 includes two straight edges 63 and an arc-shaped edge 62 located between and connecting the two straight edges 63. The two straight edges 63 are parallel to the straight edges 61, and the two straight edges 63 are connected to the two ends of the straight edges 61 through side edges 64. The arc-shaped edge 62 bends toward the straight edges 61 to form a recess. Along the direction parallel to the plane where the lower support plate 60 is located, the width of the minimum interval 66 between the arc-shaped edge 62 and the straight edge 61 is greater than 0.

[0045] The recessed portion of the upper support plate 50 and the recessed portion of the lower support plate 60 together form a receiving groove 401, and the washer 70 is located in the receiving groove 401.

[0046] The pad 90 is provided with through holes 55 / 65 that penetrate the upper support plate 50 and the lower support plate 60 along the thickness direction;

[0047] The lower support plate 60, the upper support plate 50, and the washer 70 are connected as a single unit.

[0048] Specifically, a cabinet connector 12 is provided to connect the cabinet body 10 and the cabinet door 20 of the cabinet 00. The cabinet door 20 is made of an alloy edge-sealed door panel. The cabinet connector 12 includes a hinge assembly 30 and a hinge cup washer 40. The hinge assembly 30 and the hinge cup washer 40 can be connected by fasteners, such as screws or other fastening fixtures. The hinge assembly 30 includes a hinge cup 32 and a hinge 31. The hinge 31 is rotatably connected to the hinge cup 32. The hinge 31 is fixed to the inside of the cabinet body 10 by fasteners. The hinge cup gasket 40 is fixed to the cabinet door 20 by fasteners, allowing the cabinet door 20 to open and close relative to the cabinet body 10 at an angle of not less than 90°. The hinge cup gasket 40 includes a pad 90 and a washer 70, which are fixedly connected. The pad 90 includes an upper support plate 50 and a lower support plate 60, which are parallel to and seamlessly fixedly connected to the lower support plate 60. The upper support plate 50 includes a straight edge 51 and an irregular edge 57, which are arranged opposite to each other along the width direction of the upper support plate 50. The irregular edge 57 includes two straight edges 53 and one curved edge 52. The curved edge 52 is located between the two straight edges 53 and curves towards the straight edge 51 to form a recess. The minimum distance 56 between the curved edge 52 and the straight edge 51 in the direction parallel to the plane of the upper support plate 50 is greater than 0. The two straight edges 53 are parallel to the straight edge 51 and are connected to the two ends of the straight edge 51 through the side edges 54. That is, the overall outline of the upper support plate 50 is approximately “【” shaped. The upper support plate 50 also includes a groove 80, which is located at... Between the straight edge 51 and the arc edge 52, the groove 80 forms a recess on the upper support plate 50 along the direction from the upper support plate 50 to the lower support plate 60. The groove 80 includes a left vertical edge 81, a horizontal edge 82, a right vertical edge 83, and a groove arc edge 84. The horizontal edge 82 is parallel to the straight edge 51, and the groove arc edge 84 partially overlaps with the arc edge 52. Furthermore, the groove 80 is located at the center of the straight edge 51 and the arc edge 52. That is to say, the two parts of the upper support plate 50 divided by the groove 80 are symmetrical about the groove 80 as the center of symmetry.

[0049] The lower support plate 60 includes a straight edge 61 and an irregular edge 67, which are arranged opposite each other along the width direction of the lower support plate 60. The irregular edge 67 includes two straight edges 63 and one curved edge 62, located between the two straight edges 63. The curved edge 62 bends towards the straight edge 61, forming a recess. The minimum distance 66 between the curved edge 62 and the straight edge 61 in the direction parallel to the plane of the lower support plate 60 is greater than 0. The two straight edges 63 are parallel to the straight edge 61 and connected to both ends of the straight edge 61 via side edges 64. In other words, the overall outline of the lower support plate 60 is approximately “【” shaped. The recess of the upper support plate 50 is connected to the lower support plate 60. The recessed portions of the support plate 60 overlap and together form a receiving groove 401. The washer 70 is located in the receiving groove 401 formed by the upper support plate 50 and the lower support plate 60 and is integrally connected with the upper support plate 50 and the lower support plate 60, increasing the connection strength between the pad 90 and the washer 70, making the connection between the pad 90 and the washer 70 firm, and reducing the risk of breakage between the washer 70 and the pad 90. Thus, by setting the hinge cup washer 40, which is integrally connected with the upper support plate 50, the lower support plate 60 and the washer 70, the opening angle relative to the cabinet body 10 can be not less than 90° when the cabinet door 20 adopts an alloy edge-sealed door panel, improving the user experience and extending the service life of the hinge assembly 30.

[0050] It should be noted that the material of the hinge cup washer 40 includes metal, which includes steel. Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. Steel has the characteristics of high strength, plasticity, heat resistance, good toughness, uniform material, high reliability, and good assemblability. The steel can be manganese steel, spring steel, or low carbon steel, etc.

[0051] Please continue to refer to this. Figures 3-9 The cabinet connector 12 provided in this application includes a washer 70 comprising a left convex arc 74, a concave arc 76, a right convex arc 75, a right flat arc 73, a bottom arc 71, and a left flat arc 72, which are connected in sequence to form a circle.

[0052] Along the thickness direction of the hinge cup washer 40, the heights of the left convex arc 74 and the right convex arc 75 are equal, and the heights of the left flat arc 72 and the right flat arc 73 are equal.

[0053] Along the thickness direction of the hinge cup washer 40, the height of the bottom arc 71 is less than the height of the left flat arc 72 and the right flat arc 73, the height of the left flat arc 72 and the right flat arc 73 is less than the height of the concave arc 76, and the height of the concave arc 76 is less than the height of the left convex arc 74 and the right convex arc 75.

[0054] Along the thickness direction of the hinge cup washer 40, the height of the left horizontal arc 72 and the height of the right horizontal arc 73 are the same as the height of the lower support plate 60.

[0055] Specifically, the washer 70 is composed of arcs of varying heights connected sequentially. The washer 70 includes a left convex arc 74, a concave arc 76, a right convex arc 75, a right flat arc 73, a bottom arc 71, and a left flat arc 72. The concave arc 76 coincides with the curved edge of the groove 84 and is located between the left convex arc 74 and the right convex arc 75. The bottom arc 71 is opposite to the concave arc 76 along the center of the washer 70 and is located between the left flat arc 72 and the right flat arc 73. The left flat arc 74... One end of the right horizontal arc 72 connects to the left convex arc 74, and the other end connects to the bottom arc 71. One end of the right horizontal arc 73 connects to the right convex arc 75, and the other end connects to the bottom arc 71. That is, the left convex arc 74, concave arc 76, right convex arc 75, right horizontal arc 73, bottom arc 71, and left horizontal arc 72 are connected sequentially to form a circle. Along the direction perpendicular to the plane of the pad 90, the heights of the left convex arc 74 and right convex arc 75 are equal, and the heights of the left horizontal arc 72 and right horizontal arc 73 are equal. Furthermore, the heights of the left horizontal arc 72 and the right horizontal arc 73 are greater than the height of the bottom arc 71, the height of the concave arc 76 is greater than the heights of the left horizontal arc 72 and the right horizontal arc 73, and the heights of the left convex arc 74 and the right convex arc 75 are greater than the height of the concave arc 76. Further, along the direction perpendicular to the plane of the pad 90, the height of the lower support plate 60 is the same as the heights of the left horizontal arc 72 and the right horizontal arc 73, the height of the left convex arc 74 is equal to the sum of the heights of the upper support plate 50 and the lower support, and the height of the right convex arc 75 is equal to the sum of the heights of the upper support plate 50 and the lower support. Thus, by setting washers 70 composed of arcs of varying heights, each part of the washer 70 can be matched with the height of the connection between the upper support plate 50 and the lower support plate 60, avoiding mismatches caused by abnormal protrusions in shape during installation with the hinge assembly 30, improving the matching degree between the pad 90 and the washer 70, and thereby increasing the stability of both.

[0056] Please continue to refer to this. Figures 3-9 The cabinet connector 12 provided in this application has at least a partial connection between the arc-shaped edge 52 of the upper support plate 50 and the right convex arc 75 of the washer 70, and at least a partial connection between the arc-shaped edge 52 of the upper support plate 50 and the left convex arc 74 of the washer 70.

[0057] The arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the right convex arc 75 of the washer 70, and the arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the right flat arc 73 of the washer 70; the arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the left convex arc 74 of the washer 70, and the arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the left flat arc 72 of the washer 70.

[0058] Specifically, the arc-shaped edge 52 of the upper support plate 50 is at least partially connected to the right convex arc 75 of the washer 70, and the arc-shaped edge 52 of the upper support plate 50 is at least partially connected to the left convex arc 74 of the washer 70. The arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the right convex arc 75 and the right flat arc 73 of the washer 70, and the arc-shaped edge 62 of the lower support plate 60 is at least partially connected to the left convex arc 74 and the left flat arc 72 of the washer 70. That is to say, the left convex arc 74 and the right convex arc 75 are connected to both a portion of the upper support plate 50 and a portion of the lower support plate 60. The left flat arc 72 and the right flat arc 73 are only connected to a portion of the lower support plate 60. In this way, based on the fact that the height of the left convex arc 74 / right convex arc 75 matches the height of the upper support plate 50 and the lower support plate 60, the connection between the left convex arc 74 and the upper support plate 50 and the lower support plate 60, and the connection between the right convex arc 75 and the upper support plate 50 and the lower support plate 60, can make the connection between the washer 70 and the pad 90 more stable. The fact that the left flat arc 72 and the right flat arc 73 are only connected to a portion of the lower support plate 60 can reduce the manufacturing difficulty of the washer 70 and save raw materials.

[0059] Please continue to refer to this. Figures 3-9 The cabinet connector 12 provided in this application includes a left flat arc 72, which further includes a connecting arc 722 and an empty arc 721. The connecting arc 722 is located on the side closer to the bottom arc 71, and the empty arc 721 is located on the side away from the bottom arc 71.

[0060] The right horizontal arc 73 also includes a connecting arc 732 and an empty arc 731. The connecting arc 732 is located on the side closer to the bottom arc 71, and the empty arc 731 is located on the side farther away from the bottom arc 71.

[0061] Specifically, the left horizontal arc 72 includes a connecting arc 722 and an empty arc 721. One end of the empty arc 721 is connected to the left convex arc 74, and the other end is connected to the connecting arc 722. One end of the connecting arc 722 is connected to the empty arc 721, and the other end is connected to the bottom arc 71. The right horizontal arc 73 includes a connecting arc 732 and an empty arc 731. One end of the empty arc 731 is connected to the right convex arc 75, and the other end is connected to the connecting arc 732. One end of the connecting arc 732 is connected to the empty arc 731, and the other end is connected to the bottom arc 74. 1. Connection: Thus, through the design of hollow arcs 721 / 731 in the left flat arc 72 and right flat arc 73, some raw materials can be reduced, production costs can be lowered, and the process difficulty of transitioning from the left convex arc 74 to the left flat arc 72 and from the right convex arc 75 to the right flat arc 73 can be reduced while ensuring a stable connection. It can also ensure that the side of the hinge cup gasket 40 facing the hinge cup 32 fits perfectly with the side of the hinge cup 32 facing the hinge cup gasket 40 during installation, thereby improving the stability of the cabinet connector 12.

[0062] Please continue to refer to this. Figures 3-9 This application provides a cabinet connector 12.

[0063] The open arc 731 of the right horizontal arc 73 is fixedly connected to at least part of the arc-shaped edge 62 of the lower support plate 60 along the thickness direction of the lower support plate 60, and the open arc 721 of the left horizontal arc 72 is fixedly connected to at least part of the arc-shaped edge 62 of the lower support plate 60 along the thickness direction of the lower support plate 60.

[0064] Specifically, the empty arc 721 of the left horizontal arc 72 is located between the connecting arc 722 of the left convex arc 74 and the left horizontal arc 72. The empty arc 721 of the left horizontal arc 72 is fixedly connected to at least a portion of the arc-shaped edge 62 of the lower support plate 60 along the thickness direction, providing support for the connecting arc 722 portion of the left horizontal arc 72. The empty arc 731 of the right horizontal arc 73 is located between the connecting arc 732 of the right convex arc 75 and the right horizontal arc 73. The empty arc 731 of the right horizontal arc 73 is fixedly connected to at least a portion of the arc-shaped edge 62 of the lower support plate 60 along the thickness direction. It can provide support for the connecting arc 732 of the right horizontal arc 73, and thus provide support for the bottom arc 71, further improving the connection stability between the washer 70 and the pad 90; in this way, by fixing the empty arc 721 of the left horizontal arc 72 and the empty arc 731 of the right horizontal arc 73 to at least part of the lower support plate 60 along the thickness direction, it can provide support for the suspended parts of the left horizontal arc 72 and the right horizontal arc 73, thereby providing support for the suspended parts of the washer 70 and the pad 90 that are not connected, further improving the stability of the washer 70 and the pad 90.

While achieving an opening angle of not less than 90° for the alloy edge-sealed cabinet door 20, it ensures a stable connection between the cabinet 10 and the alloy edge-sealed cabinet door 20.

[0071] Please continue to refer to this. Figures 3-9The cabinet connector 12 provided in this application has fasteners that, along a direction perpendicular to the plane where the hinge cup pad 40 is located, pass through the through holes 324 on the hinge cup fixing plate 322 and the through holes 55 / 65 on the hinge cup pad 40 to fix the hinge 31 and the hinge cup pad 40 together.

[0072] Specifically, the projection of the through hole 324 on the hinge cup fixing plate 322 in a direction perpendicular to the plane of the hinge cup pad 40 overlaps with the projection of the through hole 55 / 65 on the hinge cup pad 40 in a direction perpendicular to the plane of the hinge cup pad 40. It should be noted that there can be one or more through holes 324 on the hinge cup fixing plate 322 and one or more through holes 55 / 65 on the hinge cup pad 40. This invention does not specifically limit the number of through holes 324 on the hinge cup fixing plate 322 or the number of through holes 55 / 65 on the hinge cup pad 40; it only needs to satisfy that the projection of the through hole 55 / 65 on the hinge cup pad 40 in a direction perpendicular to the plane of the hinge cup pad 40 overlaps with the projection of the through hole 324 on the hinge cup fixing plate 322 in a direction perpendicular to the plane of the hinge cup pad 40. The through hole 324 on the hinge cup fixing plate 322 extends along the hinge cup groove 3. 21. Symmetry: The through holes 55 / 65 on the hinge cup gasket 40 are symmetrical along the washer 70. When the cabinet connector 12 provided in this application is used to install the door panel, the fasteners pass through the through holes 324 on the hinge cup fixing plate 322 and the through holes 55 / 65 on the hinge cup gasket 40 in sequence along the thickness direction of the hinge cup gasket 40 to fix the hinge cup 32, the hinge cup gasket 40 and the cabinet door 20, thereby fixing the hinge 31, the hinge cup gasket 40 and the cabinet door 20. In this way, based on the fit between the hinge cup gasket 40 and the hinge cup fixing plate 322, the projections of the through holes 55 / 65 on the hinge cup gasket 40 and the through holes 324 on the hinge cup fixing plate 322 overlap on the same plane, which allows the fasteners to pass smoothly through the hinge cup fixing plate 322 and the hinge cup gasket 40 to fix the cabinet door 20, reducing the tilting of the fasteners caused by the mismatch of the through hole positions, thus preventing unstable installation.

[0073] Please continue to refer to this. Figures 3-9 Based on the same inventive concept, this application also provides a cabinet 00, including the cabinet connector 12 as described above; the cabinet 00 includes a cabinet body 10 and a cabinet door 20, the cabinet door 20 includes an alloy edge 21, the alloy edge 21 wraps around the edge of the cabinet door 20;

[0074] Fasteners connect the hinge assembly 30 and the cabinet 10. The fasteners pass through the through holes 324 on the hinge cup fixing plate 322 and the through holes 55 / 65 on the hinge cup pad 40 in sequence along the direction perpendicular to the plane where the hinge cup pad 40 is located, and fix the hinge to the hinge cup pad 40 and the cabinet door 20.

[0075] Specifically, in one optional embodiment of this application, the cabinet 00 includes a cabinet body 10 and a cabinet door 20. The cabinet door 20 includes an alloy edge 21 and a door panel 22. Along a direction perpendicular to the plane of the cabinet door 20, the alloy edge 21 wraps around the edge of the door panel 22 along its perimeter. Fasteners pass through through holes 317 on the hinge base 314 and are fixedly connected to the inside of the cabinet body 10 along a direction perpendicular to the plane of the hinge base 314. Fasteners pass sequentially through through holes 324 on the hinge cup fixing plate 322 and the hinge cup washer along the thickness direction of the hinge cup washer 40. The through holes 55 / 65 on 40 fix the hinge cup 32, the hinge cup gasket 40 and the cabinet door 20, thereby fixing the hinge 31, the hinge cup gasket 40 and the cabinet door 20. After the cabinet 00 provided in this embodiment is installed, the opening angle is not less than 90°. Thus, the cabinet door 20 with the alloy edge 21 can be fixed to the general cabinet body 10 by only the cabinet body connector 12 and simple fasteners provided in this application, and the opening angle is not less than 90°. The installation method is simple and the installation process is simple, and it can be widely used in the home furnishing field.

[0076] In summary, the cabinet connector and cabinet provided in this application achieve at least the following beneficial effects: By setting a hinge cup washer that integrates the upper support plate, lower support plate, and washer, an opening angle of no less than 90° relative to the cabinet body can be achieved when the cabinet door uses an aluminum edge-sealed door panel, improving the user experience and extending the service life of the hinge assembly; by setting a washer composed of arcs of varying heights, the various parts of the washer can be adapted to the height of the connection parts of the upper and lower support plates, avoiding mismatches caused by abnormal protrusions in shape during hinge assembly installation, and improving the matching degree between the washer and the plate. This further increases the stability of both components; based on matching the heights of the left / right convex arcs with the heights of the upper and lower support plates, the connection between the washer and the pad is further strengthened by connecting the left convex arc to the upper and lower support plates, and the right convex arc to the upper and lower support plates; the hollow arc design of the left and right flat arcs reduces some raw materials and lowers production costs; it also reduces the difficulty of the transition connection from the left convex arc to the left flat arc and from the right convex arc to the right flat arc while ensuring a stable connection; and it allows the hinge cup washer to face the hinge cup side and the hinge cup side to the hinge cup washer during installation. The surfaces fit perfectly, enhancing the stability of the cabinet connectors; the open arcs of the left and right horizontal arcs are fixedly connected to at least part of the lower support plate along the thickness direction, providing support for the suspended parts of the left and right horizontal arcs, thus providing support for the suspended parts where the washer and the pad are not connected, further improving the stability of the washer and the pad; by setting hinge components adapted to the structural dimensions of the hinge cup pad, the hinge components and hinge cup pads can work together when the aluminum-edged door panel is used as the cabinet door, ensuring that the opening angle of the aluminum-edged cabinet door is not less than 90° while maintaining the stability of the cabinet body and the aluminum-edged cabinet door. The hinge cup washer and the hinge cup fixing plate are fitted in shape. The through holes on the hinge cup washer and the through holes on the hinge cup fixing plate are made to overlap on the same plane. This allows the fasteners to pass smoothly through the hinge cup fixing plate and the hinge cup washer to fix the cabinet door. It reduces the tilting of the fasteners caused by the mismatch of the through hole positions, which would lead to unstable installation. The cabinet door with the alloy edge can be fixed to the general cabinet body through the cabinet connector and simple fasteners provided in this application. It can also open with an opening angle of not less than 90°. The installation method is simple and the installation process is easy. It can be widely used in the home furnishing field.
