Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a cabinet hinge. Background Art

[0002] Typical cabinets in the home, such as cabinets or freezers, usually have doors connected by hinges to achieve pivoting. In the development of cabinets, the need to open the doors of the upper and lower cabinets simultaneously or separately has gradually become a user demand. In order to solve this technical problem, two hinges are often respectively set on the cabinets corresponding to the upper cabinet door and the lower cabinet door, and the two hinges are respectively connected to the upper and lower cabinet doors, so as to meet the user's needs to open the cabinet doors simultaneously or separately. However, this method often requires a cabinet position that is large enough and thick enough to set the two hinges to ensure that there is no interference between the two hinges, which results in a reduction in the actual usable space in the cabinet and is not beautiful in appearance. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a cabinet hinge capable of opening at least two cabinet doors separately or simultaneously.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A cabinet hinge is applied to a cabinet having at least two door bodies arranged in an up and down direction. The cabinet hinge includes a cabinet fixing seat fixed to the cabinet and a pair of hinge assemblies accommodated in the cabinet fixing seat.

[0015] Compared with the prior art, the cabinet hinge of the utility model has the following advantages:

[0016] (1) Since the cabinet hinge includes a pair of hinge assemblies that are independently pivoted and arranged on the cabinet fixing seat, wherein the pair of hinge assemblies are pivotally connected to the cabinet fixing seat through a connecting component and pivot independently of each other, when the cabinet hinge is applied to the cabinet, the two door bodies connected to the pair of hinge assemblies can be opened or closed at the same time, or opened or closed separately. Moreover, a cabinet hinge has a pair of hinge assemblies that are independently pivoted, which occupies less space in the cabinet, thereby increasing the internal volume of the cabinet and having less impact on the appearance of the cabinet.

[0017] (2) The cabinet hinge also includes a deceleration component. When the door needs to be closed, the arc-shaped protrusion of the third connecting member contacts the deceleration component, thereby reducing the closing speed of the door and improving the safety of the door closing.

[0018] (3) The structural design of the cabinet hinge enables the hinge to have a larger opening when opened, which is suitable for different usage scenarios; when closed, the first connecting member, the second connecting member, the third connecting member and the fourth connecting member are accommodated between the cabinet fixing seat and the door fixing seat, so that the hinge is small in size and does not take up space.

[0019] (4) The cabinet fixing base, the door fixing base, the first connecting member, the second connecting member and the fourth connecting member are all double-sided plate structures. When the cabinet hinge is closed or opened, the first connecting member, the second connecting member, the third connecting member and the fourth connecting member are in different positions and form different gaps. At this time, the double-sided plate structure of the connecting member protects other components. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] like Figure 1-18As shown, the cabinet hinge 100 of the utility model is applied to a cabinet having at least two door bodies arranged in the up-down direction, and the cabinet hinge 100 comprises a cabinet fixing seat 101 fixed to the cabinet and a pair of hinge components accommodated in the cabinet fixing seat 101. Each hinge component in the pair of hinge components is independently and symmetrically arranged, and each hinge component is respectively connected to the two door bodies of the cabinet, and the pair of hinge components comprises a first hinge component 102 and a second hinge component 103 arranged in a radial direction perpendicular to the up-down direction and penetrating the inside and outside of the cabinet, and the first hinge component 102 and the second hinge component 103 are fixed to the cabinet fixing seat 101 through a connecting component and independently pivot. Since the cabinet hinge 100 includes a pair of hinge assemblies independently pivoted on the cabinet fixing seat 101, wherein the pair of hinge assemblies are pivotally connected to the cabinet fixing seat 101 through a connecting component and pivot independently of each other, when the cabinet hinge 100 is applied to the cabinet, the two door bodies connected to the pair of hinge assemblies can be opened or closed at the same time, or opened or closed separately. This makes the operation more convenient and convenient for users to take things in different cabinet doors. At the same time, the cabinet volume of the cabinet occupied by the cabinet hinge 100 is small, which correspondingly increases the actual application volume inside the cabinet, and the cabinet hinge 100 has little effect on the appearance of the cabinet. The connecting component here includes a first connecting shaft 104 and a second connecting shaft 105 in this embodiment. In other embodiments, the connecting component can also be in other forms.

[0043] The connecting component includes the first connecting shaft 104 that penetrates the cabinet fixing seat 101, the first hinge assembly 102, the first connecting member 30 and the elastic assembly 70, the second hinge assembly 103 along the radial direction, and the second connecting shaft 105 that penetrates the cabinet fixing seat 101, the first hinge assembly 102, and the third connecting member 50 of the second hinge assembly 103 along the radial direction.

[0044] Please refer to Figures 1 to 4 as well as Figure 7The cabinet fixing seat 101 is a double-side plate structure, including a bottom side 1015, a pair of side stoppers 1012 located on both sides of the bottom side 1015, and an extension side 1016 connecting the bottom side 1015 and the side stoppers 1012. The bottom side 1015, the side stoppers 1012, and the extension side 1016 are jointly formed to form a receiving groove 1011 for receiving the first hinge assembly 102 and the second hinge assembly 103. A first fixing hole 1013 and a second fixing hole 1014 are formed on each of the side stoppers 1012. The first connecting shaft 104 is fixedly passed through the first fixing hole 1013, and the second connecting shaft 105 is fixedly passed through the second fixing hole 1014. A sliding groove 1017 extending along the up-down direction is formed on the extension side 1016.

[0045] Each of the hinge components includes a door body fixing seat 20 fixed to the cabinet door body, the door body fixing seat 20 of the first hinge component 102 is fixed to one of the two door bodies of the cabinet, and the door body fixing seat 20 of the second hinge component 103 is fixed to the other of the two door bodies of the cabinet. Since the first hinge component 102 and the second hinge component 103 are fixed to each other through the first connecting shaft 104 and the second connecting shaft 105, and the first connecting shaft 104 and the second connecting shaft 105 are fixed to the cabinet fixing seat 101 through both sides of the radial direction, and are respectively pivotally connected to the cabinet fixing seat 101, such a separate arrangement can make it possible for the user to only need to act on the door body connected to the corresponding hinge component when he needs to open one door body of the cabinet, so as to realize the simultaneous opening or closing of the cabinet doors, or the separate opening or closing.

[0046] The door body fixing seat 20 is a double-side plate structure, including a bottom plate 21 and a pair of side plates 22 located on the bottom plate 21. Each side plate 22 is provided with a first holding hole 221 and a second holding hole 222, and the door body fixing seat 20 also includes a first holding shaft 223 penetrating and fixed in the first holding hole 221 and a second holding shaft 224 penetrating and fixed in the second holding hole 222.

[0047] Each of the hinge components further includes a first connecting member 30 , a second connecting member 40 , a third connecting member 50 , a fourth connecting member 60 , an elastic component 70 , a supporting component 80 and a deceleration component 90 .

[0048] Please refer to Figures 1 to 4 as well as Fig. 9, the first connecting member 30 is a double-side plate structure, and the two ends of the first connecting member 30 are pivotally connected to the cabinet fixing seat 101 and the second connecting member 40 respectively. The first connecting member 30 includes a bottom straight plate 31 and a pair of side straight plates 32 located on both sides of the bottom straight plate 31. The bottom straight plate 31 is provided with a notch 310 so that the bottom straight plate 31 is divided into two. The bottom straight plate 31 also has an arc-shaped extension portion 311 formed by an upward curved arc extension. The side straight plate 32 is also provided with a first through hole 321, a second through hole 322 and a third through hole 323. The second through hole 322 is located in the middle position between the first through hole 321 and the third through hole 323. The side straight plate 32 also includes a slide groove 320 arranged between the first through hole 321 and the second through hole 322 and close to the second through hole 322. The first connecting member 30 further includes a first through-shaft 324 penetrating and fixedly disposed in the second through-hole 322 and a second through-shaft 325 penetrating and fixedly disposed in the third through-hole 323. The first through-hole 321 is opposite to the first fixing hole 1013 of the cabinet fixing seat 101, and both are penetrated and fixedly disposed by the first connecting shaft 104. The arc-shaped extension portion 311 is arranged in an arc shape around the second through-shaft 325, and the shape of the arc-shaped extension portion 311 is adapted to the second through-shaft 325.

[0049] Please refer to Figures 1 to 4 as well as Fig.10 The second connecting member 40 is a double-sided plate structure, and the two ends of the second connecting member 40 are pivotally connected to the first connecting member 30 and the door body fixing seat 20 respectively. The second connecting member 40 includes a bottom wall 41 and side walls 42 extending vertically from both sides of the bottom wall 41. The side walls 42 are also provided with a first clamping hole 421 and a second clamping hole 422. The first clamping hole 421 is opposite to the third through hole 323, and both are penetrated and fixed by the second through shaft 325 so that the first connecting member 30 and the second connecting member 40 can rotate around the second through shaft 325. The second clamping hole 422 is opposite to the first holding hole 221, and both are penetrated and fixed by the first holding shaft 223, so that the door body fixing seat 20 can drive the second connecting member 40 to rotate in the clockwise direction to close or rotate in the counterclockwise direction to open.

[0050] Please refer to Figures 1 to 4 as well as Fig.11 and Fig.12, the two ends of the third connecting member 50 are pivotally connected to the cabinet fixing seat 101 and the fourth connecting member 60 respectively. The third connecting member 50 is provided with an arc-shaped protrusion 513 to slide against the deceleration assembly 90 to reduce its closing speed when the cabinet hinge 100 is closed. The third connecting member 50 includes a main body 51, a first fixed end 52 fixedly connected to the fourth connecting member 60, and a second fixed end 53 fixedly connected to the cabinet fixing seat 101. The first fixed end 52 is provided with a through hole (not numbered) corresponding to the middle position of the fourth connecting member 60, and is fixedly provided on the fourth connecting member 60 by a fixed through shaft 54. The second fixed end 53 is provided with a through hole (not numbered) corresponding to the second fixing hole 1014, and both are fixedly provided by the second connecting shaft 105, so that the third connecting member 50 can be rotated in the clockwise direction to open and rotated in the counterclockwise direction to close. The third connecting member 50 includes an inner wall surface 511 close to the elastic component 70 and an outer wall surface 512 away from the elastic component 70. The arc-shaped convex portion 513 is integrally extended from the inner wall surface 511, and the size of the arc-shaped convex portion 513 gradually expands from the end away from the deceleration component 90 to the end close to the deceleration component 90. When the cabinet hinge 100 is in a fully closed state, the arc-shaped convex portion 513 abuts against the deceleration component 90. When it is necessary to change from the closed state to the open state, it is necessary to apply an external force on the door body fixing seat 20 to overcome the force between the arc-shaped convex portion 513 and the deceleration component 90. When the cabinet hinge 100 changes from the open state to the closed state, the arc-shaped convex portion 513 changes from the side with a larger size to the side with a smaller size, which can reduce the closing speed of the cabinet door and ensure the safety of the door closing.

[0051] Please refer to Fig.12 The third connecting member 50 also includes a convex rib 514 integrally protruding from the outer wall surface 512 to enhance the strength of the third connecting member 50 so that it will not break due to force during the closing or opening process of the cabinet hinge 100.

[0052] Please continue to refer to Figures 1 to 6 as well as Fig.13As shown, the fourth connecting member 60 is a double-side plate structure, and the two ends of the fourth connecting member 60 are pivotally connected to the first connecting member 30 and the door body fixing seat 20 respectively. The fourth connecting member 60 includes a pair of side plate portions 61 and a hook-shaped holding plate 62 fixed between the pair of side plate portions 61, and the hook-shaped holding plate 62 includes protruding blocks 621 arranged on both sides and an arc-shaped hook portion 622 formed by arc bending at one end. The protruding blocks 621 are fixedly clamped with the pair of side plate portions 61. In this embodiment, three protruding blocks 621 are arranged on both sides of the hook-shaped holding plate 62. In other embodiments, the shape and number of the protruding blocks 621 are not limited. The side plate portion 61 includes a first connecting hole 611, a second connecting hole 612, a third clamping hole 613 and a fourth clamping hole 614 located between the first connecting hole 611 and the second connecting hole 612. The side plate portion 61 is also provided with fixing retaining holes 615 corresponding to the number of the protruding blocks 621, and the protruding blocks 621 cooperate with the fixing retaining holes 615. The first connecting holes 611 are provided corresponding to the second through holes 322, and are both penetrated and fixed by the first through shaft 324. The second connecting holes 612 are provided corresponding to the second retaining holes 222, and are both penetrated and fixed by the second retaining shaft 224. The arc-shaped hook portion 622 is hooked to the shaft portion penetrating the pair of side plate portions 61, i.e., the second retaining shaft 224, and a space for accommodating the abutting component 80 is provided in the fourth connecting member 60 on the side of the hook-shaped retaining plate 62 close to the elastic component 70.

[0053] Please continue to refer to Figures 15 to 18As shown, one end of the elastic component 70 is pivotally arranged on the cabinet fixing seat 101, and the other end of the elastic component 70 is slidably arranged on the first connecting member 30 and slidably abuts against the abutting component 80 accommodated and fixed in the fourth connecting member 60 to drive the cabinet hinge 100 to close and open. The elastic component 70 includes a base 71 penetrated by the first connecting shaft 104, a fixing pillar 72 extending upward from the base 71, a fixing portion 721 arranged at the top of the fixing pillar 72, and an elastic element 73 sleeved outside the fixing pillar 72. The base 71 is provided with a fourth through hole 711 penetrating in the radial direction, and the fourth through hole 711 is opposite to the first through hole 321 and the first fixing hole 1013, and both are penetrated and fixed by the first connecting shaft 105. The fixing portion 721 includes a receiving groove 7211 and supporting grooves 7212 located on both sides of the receiving groove 7211. The elastic component 70 also includes a roller portion 74 that is accommodated and rolled in the accommodating groove 7211 and a mounting support shaft 75 that penetrates the roller portion 74 along the radial direction and is mounted on the supporting groove 7212. The mounting support shaft 75 penetrates the slide groove 320 set in the first connecting member 30 and is slidably set in the slide groove 320 under the action of the elastic element 73.

[0054] The abutting assembly 80 is received in the fourth connecting member 60, and the abutting assembly 80 includes a main body 81 and a holding shaft 82 held at one end of the main body 81. The main body 81 has a first holding end 811 close to the elastic assembly 70 and a second holding end 812 away from the elastic assembly 70. The first holding end 811 protrudes toward the elastic assembly 70 and is provided with a cam rotating portion 8112, and the cam rotating portion 8112 is slidably held against the roller portion 74 so that the elastic assembly 70 rotates counterclockwise and closes. The first holding end 811 is provided with a first holding through hole 8111, and the first holding through hole 8111 is opposite to the first connecting hole 611 and the second through hole 322, and both are penetrated and fixed by the first through shaft 324. The second holding end 812 is provided with a second holding through hole 8121, and the second holding through hole 8121 is opposite to the third clamping hole 613, and both are penetrated and fixed by the holding shaft 82. The retaining shaft 82 passes through one side of the third retaining hole 613 of the fourth connecting member 60 and is held against the inner wall of the first connecting member 30 .

[0055] The first fixing end 811 of the supporting component 80 and the fixing portion 721 and the roller portion 74 of the elastic component 70 are exposed to the notch 310 provided in the first connecting member 30, so that during the opening or closing process of the cabinet hinge 100, the movement of each joint will not be interfered by the first connecting member 30, thereby preventing the opening and closing of the cabinet hinge 100.

[0056] The deceleration assembly 90 includes a damping frame 91, a support rod 92 disposed in the damping frame 91, and a slider 93 disposed outside the damping frame 91 and sliding in the slide groove 1017 of the cabinet fixing seat 101. The deceleration assembly 90 is disposed in the receiving groove 1011 of the cabinet fixing seat 101, and is limited by the base 71 of the elastic assembly 70 and the second fixed end 53 of the third connecting member 50.

[0057] In this embodiment, the first hinge assembly 102 and the second hinge assembly 103 are independently arranged on the cabinet fixing seat 101, and the first hinge assembly 102 and the second hinge assembly 103 are fixedly connected to the cabinet fixing seat 101 only through the first connecting shaft 104 and the second connecting shaft 105. When the user needs to open the two doors of the cabinet at the same time, he can apply force on the two doors at the same time, thereby driving the door fixing seat 20 of the first hinge assembly 102 and the second hinge assembly 103 to rotate in the clockwise direction, thereby driving the second connecting member 40, the fourth connecting member 60, the third connecting member 50 and the first connecting member 30 to move, thereby completing the opening process of the cabinet door. In this process, the opening process of the first hinge assembly 102 will not affect the opening process of the second hinge assembly 103. And in this process, the arc-shaped protrusion 513 of the third connecting member 50 of a pair of hinge assemblies is separated from the deceleration assembly 90 from being abutted against the deceleration assembly 90. In this process, the force applied by the user to the door fixing seat 20 is greater than the force between the arc-shaped protrusion 513 and the deceleration assembly 90. At the same time, since the pair of hinge assemblies are symmetrically arranged in the radial direction perpendicular to the up and down direction, the size occupied by the cabinet hinge 100 can also be reduced, which has little impact on the appearance of the cabinet.

[0058] When the first hinge assembly 102 and the second hinge assembly 103 need to be changed from an open state to a closed state, force is also applied to the door body fixing seat 20. During this process, the arc-shaped protrusion 513 of the third connecting member 50 of a pair of hinge assemblies separates from the deceleration assembly 90 and then abuts against the deceleration assembly 90, thereby slowing down the closing speed of the door body fixing seat 20 and preventing damage to the cabinet door.

[0059] Since the cabinet hinge includes a pair of hinge components independently pivoted on the cabinet fixing seat, wherein the pair of hinge components are pivotally connected to the cabinet fixing seat through a connecting component and pivot independently of each other, when the cabinet hinge is applied to the cabinet, the two door bodies connected to the pair of hinge components can be opened or closed at the same time, or opened or closed separately. The cabinet hinge has a pair of hinge components that are independently pivoted, which occupies a smaller space in the cabinet, thereby increasing the actual working volume inside the cabinet, while having less impact on the appearance of the cabinet.

[0060] The cabinet hinge also includes a deceleration component. When the door needs to be closed, the arc-shaped protrusion of the third connector contacts the deceleration component, which reduces the closing speed of the door and improves the safety of the door closing. The structural design of the cabinet hinge allows the hinge to have a larger opening when opened, which is suitable for different usage scenarios. When closed, the first connector, the second connector, the third connector and the fourth connector are accommodated between the cabinet fixing seat and the door fixing seat, so that the hinge is small in size and does not take up space. The cabinet fixing seat, the door fixing seat, the first connector, the second connector and the fourth connector are all double-sided plate structures. When the cabinet hinge is closed or opened, the first connector, the second connector, the third connector and the fourth connector are in different positions and form different gaps. At this time, the double-sided plate structure of the connector protects other components.

[0061] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
