DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] Common cabinets include cabinet bodies and cabinet doors. In order to facilitate the opening and closing of the cabinet doors, some cabinets with larger spaces have double-door cabinet doors to facilitate the opening and closing of the cabinet doors. Generally speaking, the cabinet doors are connected to the cabinet body through hinges. Due to the machining tolerances and assembly tolerances of the cabinet body and cabinet doors during the manufacturing process, the installation position of the cabinet doors may deviate. When the cabinet has double doors, the two cabinet doors may also be inconsistent in height.

[0031] Based on this, an embodiment of the present application provides a cabinet to solve the above problems.

[0032] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application.

[0033] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0034] Figure 1 This is a schematic diagram of the structure of the cabinet provided in the embodiment of the present application. Figure 1 The cabinet includes a cabinet body 10, a cabinet door 20, a hinge 30 and an adjustment structure 40. The cabinet body 10 includes a top plate 11, a bottom plate 12 and a side plate 13. The top plate 11 and the bottom plate 12 are arranged relative to each other. The side plate 13 connects the top plate 11 and the bottom plate 12. The side plates 13, the top plate 11 and the bottom plate 12 form a cabinet body 10 having a receiving cavity with at least one end open. In one embodiment, the cabinet body 10 includes a top plate 11, a bottom plate 12, a frame and a side plate 13. The top plate 11 and the top plate 11 are arranged relative to the frame. The side plates 13 are fixed to the frame. The side plates 13 connect the top plate 11 and the bottom plate 12. The frame, the side plates 13, the top plate 11 and the bottom plate 12 form a cabinet body 10 having a receiving cavity with at least one end open.

[0035] One end of the hinge 30 is fixedly connected to the cabinet body 10, and the other end of the hinge 30 is used to be rotatably connected to the cabinet door 20. Specifically, each cabinet door 20 is connected to the cabinet door 20 by at least two hinges 30, and at least two hinges 30 are arranged at intervals along the arrangement direction of the top plate 11 and the bottom plate 12 to ensure the stability of the connection between the cabinet door 20 and the cabinet body 10. When the cabinet body 10 includes a frame, one end of the hinge 30 is fixed to the frame, and when the cabinet body 10 does not have a frame, one end of the hinge 30 is fixed to the side plate 13. The cabinet door 20 and the hinge 30 are rotatably connected to the cabinet body 10 to control the opening and closing of the accommodating cavity.

[0036] Figure 2 for Figure 1 A partial schematic diagram of Figure 3 A schematic diagram of a structure of a cabinet door and hinge connection provided in an embodiment of the present application. Figure 1 , Figure 2 and Figure 3The other end of the hinge 30 includes a mounting hole 31, and the extension direction of the mounting hole 31 is the arrangement direction of the bottom plate 12 and the top plate 11. The cabinet door 20 may include a cabinet door body 21 and a door shaft 22, and the cabinet door body 21 includes an avoidance portion, and the door shaft 22 is installed in the avoidance portion. The adjustment structure 40 is rotatably installed in the mounting hole 31, and the rotation of the adjustment structure 40 can make the adjustment structure 40 move along the extension direction of the mounting hole 31, so as to drive the cabinet door 20 to move along the arrangement direction of the bottom plate 12 and the top plate 11.

[0037] In one embodiment, one end of the door shaft 22 is fixed to the cabinet door body 21, and the other end of the door shaft 22 faces the bottom plate 12, and the door shaft 22 is rotatably installed in the installation hole 31 and abuts against the adjustment structure 40. By rotating the adjustment structure 40, the door shaft 22 can be driven to move toward or away from the bottom plate 12, thereby adjusting the position of the cabinet door 20 installed on the cabinet body 10. In this way, when the position installation of the cabinet door 20 deviates, the adjustment structure 40 is directly rotated, and the adjustment structure 40 can drive the cabinet door 20 to move, thereby adjusting the position of the cabinet door 20, so as to simplify the difficulty of adjusting the cabinet door 20.

[0038] In one embodiment, one end of the door shaft 22 is fixed to the cabinet door body 21, and the other end of the door shaft 22 extends toward the bottom plate 12. And the other end of the door shaft 22 is rotatably installed in the adjustment structure 40, and the adjustment structure 40 is rotated to move the position of the adjustment structure 40 in the installation hole 31 toward or away from the bottom plate 12. In this way, when the position installation of the cabinet door 20 deviates, since the door shaft 22 of the cabinet door 20 is installed on the adjustment structure 40, the adjustment structure 40 is directly rotated, and the position of the adjustment structure 40 changes, so that the position of the cabinet door 20 can be adjusted, thereby simplifying the difficulty of adjusting the cabinet door 20.

[0039] In the above-mentioned embodiment, the adjustment structure 40 includes a threaded portion 41, and the mounting hole 31 includes a threaded mounting portion 310, and the threaded portion 41 of the adjustment structure 40 cooperates with the threaded mounting portion 310 of the mounting hole 31. The thread that the threaded portion 41 may include may be an internal thread or an external thread, and the thread that the threaded mounting portion 310 includes may be an external thread or an internal thread. The threaded portion 41 of the adjustment structure 40 cooperates with the threaded mounting portion 310 of the mounting hole 31 so that the adjustment structure 40 can be fixed in the mounting hole 31. One end of the adjustment structure 40 extends into the mounting hole 31 from the mounting hole 31 toward the side of the bottom plate 12, and one end of the adjustment structure 40 abuts against one end of the door shaft 22 toward the bottom plate 12. When the adjustment structure 40 is rotated, when the adjustment structure 40 moves toward the side close to the bottom plate 12 in the mounting hole 31, the door shaft 22 will move toward the side of the bottom plate 12 along with the adjustment structure 40 under the action of gravity. When the adjusting structure 40 is rotated and the adjusting structure 40 moves in the mounting hole 31 toward the side away from the bottom plate 12, the door shaft 22, under the push of the adjusting structure, will move along with the adjusting structure 40 toward the side away from the bottom plate 12, thereby adjusting the position of the cabinet door 20. In this way, the position of the cabinet door 20 can be adjusted by simply rotating the adjusting structure 40, which simplifies the difficulty of adjusting the position of the cabinet door 20. In addition, adjusting the position of the cabinet door 20 by rotating the adjusting structure 40 will not increase the complexity of the hinge 30 structure. The extension direction of the adjusting structure 40 is the same as the extension direction of the mounting hole 31 and the door shaft 22, which can ensure the bearing capacity of the hinge 30, and the threaded fit between the adjusting structure 40 and the mounting hole 31 can ensure the accuracy of the adjusting structure 40, so that the position of the cabinet door 20 is more accurate.

[0040] In one embodiment, the mounting hole 31 further includes at least one non-threaded mounting portion 311, and the inner diameter of the non-threaded mounting portion 311 is larger than the inner diameter of the threaded mounting portion 310. In one embodiment, there are two non-threaded mounting portions 311, and the two non-threaded mounting portions 311 are located on both sides of the threaded mounting portion 310, and the two non-threaded mounting portions 311 are connected to the threaded mounting portion 310. The adjustment structure 40 includes an end portion 42 connected to the threaded portion 41, wherein the outer diameter of the end portion 42 is smaller than the outer diameter of the threaded portion 41, and when the adjustment structure 40 is installed in the mounting hole 31, the end portion 42 passes through the threaded mounting portion 310 of the mounting hole 31 and abuts against the door shaft 22 located in the non-threaded mounting portion 311. When the position of the cabinet door 20 needs to be adjusted, the adjustment structure 40 is rotated, and the end portion 42 moves to the side away from the bottom plate 12, and the end portion 42 pushes the door shaft 22 to move to the side away from the bottom plate 12. When the adjusting structure 40 is rotated and the end portion 42 moves toward the side close to the bottom plate 12 , the door shaft 22 moves toward the side of the bottom plate 12 under the action of the gravity of the cabinet door 20 to adjust the position of the cabinet door 20 .

[0041] The outer diameter of the end portion 42 is smaller than the outer diameter of the threaded portion 41, and the outer diameter of the end portion 42 gradually decreases along the direction from the bottom plate 12 to the top plate 11. The end of the end portion 42 away from the threaded portion 41 has a reduced size, which can reduce the matching area between the end portion 42 and the end of the door shaft 22, reduce the friction between the adjustment structure 40 and the door shaft 22, and improve the stability of the matching between the adjustment structure 40 and the door shaft 22.

[0042] Figure 4 A schematic diagram of a structure of an adjustment structure in a cabinet provided in an embodiment of the present application, referring to Figure 3 and Figure 4 In the above-mentioned embodiment, the adjusting structure 40 is a set screw 52 , which can improve the stability of the threaded connection between the adjusting structure 40 and the mounting hole 31 .

[0043] Figure 5 A schematic diagram of a structure of a first anti-loosening structure included in the cabinet provided in the embodiment of the present application; Figure 6 Another structural schematic diagram of a cabinet including a first anti-loosening structure provided in an embodiment of the present application. Figure 3 , Figure 5 and Figure 6 In one embodiment, the cabinet includes a first anti-loosening structure 50a, and the first anti-loosening structure 50a is located between the inner wall of the mounting hole 31 and the adjustment structure 40. Specifically, it can be understood that the first anti-loosening structure 50a is located between the non-threaded mounting portion 311 and the threaded portion 41 of the adjustment structure 40. Among them, the first anti-loosening structure 50a is a thread glue 53 or a rubber ring 51. When the first anti-loosening structure 50a is a rubber ring 51, the rubber ring 51 is sleeved on the side of the adjustment structure 40 close to the bottom plate 12, and the rubber ring 51 is located between the adjustment structure 40 and the non-threaded mounting portion 311. When the adjustment structure 40 adjusts one cabinet door 20 to a set position, or adjusts two cabinet doors 20 to a flush position, the setting of the rubber ring 51 can improve the stability of the adjustment structure 40 and prevent the adjustment structure 40 from moving under the gravity of the cabinet door 20 or the rotation of the door shaft 22.

[0044] When the first anti-loosening structure 50a is a thread glue 53, the thread glue 53 is filled between the adjustment structure 40 and the non-threaded mounting portion 311. Specifically, it can be understood that the thread glue 53 can be filled between the threaded mounting portion 310 and the opening of the mounting hole 31 toward the bottom plate 12. When the adjustment structure 40 adjusts a cabinet door 20 to a set position, or adjusts two cabinet doors 20 to a flush position, the thread glue 53 is filled between the adjustment structure 40 and the non-threaded mounting portion 311. The setting of the thread glue 53 can improve the stability of the adjustment structure 40 and prevent the adjustment structure 40 from moving under the gravity of the cabinet door 20 or the rotation of the door shaft 22.

[0045] Figure 7A schematic diagram of a structure including a second anti-loosening structure in a cabinet provided in an embodiment of the present application. Figure 3 and Figure 7 In one embodiment, the cabinet includes a second anti-loosening structure 50b, and the second anti-loosening structure 50b includes a first elastic member 54 and a positioning flange 55. The positioning flange 55 is located in the non-threaded mounting portion 311 of the mounting hole 31, and the positioning flange 55 is arranged between the threaded mounting portion 310 and the opening of the mounting hole 31 toward the top plate. One end of the door shaft 22 facing the bottom plate 12 passes through the positioning flange 55, one end of the first elastic member 54 is sleeved between the threaded portion 41 and the non-threaded mounting portion 311, and the other end of the first elastic member 54 abuts against the positioning flange 55. The first elastic member 54 will generate torque as the threaded portion 41 rotates, thereby improving the stability of the threaded connection between the adjustment structure 40 and the mounting hole 31.

[0046] In the above embodiment, the end of the threaded portion 41 away from the end portion 42 includes a rotation interface, which can be understood as when the adjustment structure 40 is installed in the mounting hole 31, the end of the threaded portion 41 facing the bottom plate 12 includes a rotation interface. The rotation interface is a hexagonal interface, an external hexagonal interface, a cross slot interface, or a slotted interface.

[0047] Figure 8 A schematic diagram of another structure of the cabinet door and hinge connection provided in an embodiment of the present application; Fig. 9 for Figure 8 Schematic diagram of the structure of the middle hinge; Fig.10 for Figure 8 Another structural diagram of the regulating structure in FIG. Figure 8 , Fig. 9 and Fig.10In one embodiment, the adjustment structure 40 includes a threaded portion 41, the threaded portion 41 includes an external thread, the mounting hole 31 includes a threaded mounting portion 310 and a non-threaded mounting portion 311, and the external thread of the threaded portion 41 cooperates with the internal thread included in the threaded mounting portion 310. The adjustment structure 40 includes a fixing hole 410, the opening of the fixing hole 410 faces the top plate 11, and the door shaft 22 is rotatably installed in the fixing hole 410. When the cabinet door 20 rotates, the door shaft 22 rotates relative to the adjustment structure 40, and the extension direction of the adjustment structure 40 is the same as that of the mounting hole 31. The setting of the adjustment structure 40 does not affect the strength of the hinge 30, ensuring the strength of the cabinet door 20 installed on the hinge 30 through the adjustment structure 40, thereby improving the stability of the cabinet. In addition, the adjustment structure 40 and the mounting hole 31 are threadedly matched, and the adjustment structure 40 can be rotated to adjust the adjustment structure 40 to move closer to or away from the bottom plate 12. It can be understood that the distance between the adjustment structure 40 and the bottom plate 12 can be adjusted by rotating the adjustment structure 40, thereby adjusting the distance between the cabinet door 20 and the bottom plate 12, and the adjustment accuracy of the threaded adjustment structure 40 and the mounting hole 31 is relatively high, thereby improving the convenience of adjusting the second adjustment structure 40.

[0048] In the above embodiment, the adjustment structure 40 further includes a connection portion 43 and a leveling flange 44, one end of the connection portion 43 is connected to the threaded portion 41, the other end of the connection portion 43 extends toward the side of the mounting hole toward the bottom plate, and the leveling flange 44 is fixedly connected to the other end of the threaded portion 41, wherein the other end of the threaded portion 41 extends to the outside of the mounting hole, and the leveling flange 44 is located between the mounting hole 31 and the top plate 11. In this manner, when the adjustment structure 40 needs to move toward or away from the side of the bottom plate 12, a force is applied to the leveling flange 44 to rotate the leveling flange 44, and the leveling flange 44 can drive the entire adjustment structure 40 to rotate, thereby causing the adjustment structure 40 to move toward or away from the bottom plate 12. The number of turns of the leveling flange 44 is related to the distance that the adjustment structure 40 moves toward or away from the bottom plate 12, and when the leveling flange 44 drives the entire adjustment structure 40 to rotate, the cabinet door 20 may not rotate relative to the cabinet body 10.

[0049] The peripheral side of the leveling flange 44 may be serrated to increase the frictional force in contact with the leveling flange 44 , thereby increasing the speed at which the adjustment structure 40 is driven by the leveling flange 44 to move closer to or away from the base plate 12 .

[0050] In one embodiment, the first anti-loosening structure is arranged between the adjustment structure and the mounting hole. The arrangement of the first anti-loosening structure can improve the stability of the threaded connection between the adjustment structure 40 and the mounting hole 31. It can be understood that after the adjustment structure 40 adjusts the cabinet door 20 to the required position, the position of the adjustment structure 40 relative to the mounting hole 31 can be stable. Specifically, the first anti-loosening structure includes a rubber ring or a threaded glue, and the rubber ring is sleeved between the connecting portion 43 and the non-threaded mounting portion 311. The non-threaded mounting portion 311 is the portion between the threaded mounting portion and the mounting hole 310 facing the bottom plate, wherein the rubber ring and the connecting portion are interference fit. When the adjustment structure 40 adjusts one cabinet door 20 to a set position, or adjusts two cabinet doors 20 to a flush position, the arrangement of the rubber ring can improve the stability of the adjustment structure 40 in the mounting hole 31, and prevent the adjustment structure 40 from moving under the gravity of the cabinet door 20 or the rotation of the door shaft 22.

[0051] When the first anti-loosening structure is a thread glue, the thread glue is filled between the connection part 43 and the non-threaded mounting part 311, and the non-threaded mounting part 311 is the part between the threaded mounting part 310 and the mounting hole 31 facing the bottom plate. When the adjustment structure 40 adjusts one cabinet door 20 to a set position, or adjusts two cabinet doors 20 to a flush position, the thread glue is filled between the connection part and the inner wall of the non-threaded mounting part. The setting of the thread glue can improve the stability of the adjustment structure 40 in the mounting hole 31, and prevent the adjustment structure 40 from moving under the gravity of the cabinet door 20 or the rotation of the door shaft 22.

[0052] In one embodiment, the cabinet includes a third anti-loosening structure, which includes a second elastic member, and the threaded portion 41 passes through the second elastic member (not shown in the figure), wherein one end of the second elastic member is located between the threaded portion 41 and the threaded mounting portion 310, and the other end of the second elastic member abuts against the leveling flange 44. When the leveling flange 44 rotates, the second elastic member also rotates with the leveling flange 44, and the second elastic member generates torque when rotating, thereby improving the stability of the adjustment structure 40 installed in the mounting hole 31.

[0053] In the above-mentioned embodiment, the end of the adjustment structure 40 away from the fixing hole 410 includes a rotation interface. It can be understood that the end of the connection portion 43 away from the threaded portion 41 includes a rotation interface. When the adjustment structure 40 is installed in the mounting hole 31, the end of the connection portion facing the base plate 12 includes a rotation interface. Among them, the rotation interface is an internal hexagon interface, an external hexagon interface, a cross slot interface or a slot interface, etc. Both the leveling flange 44 and the rotation interface can adjust the position of the adjustment structure 40 in the mounting hole 31.
