[0053] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0054] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 2 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0055] In the related art, the first hinge seat of the hinge is connected to the cabinet door, the second hinge seat is arranged on the first hinge seat, the first hinge seat at least partially rotates relative to the second hinge seat, and the second hinge seat of the hinge is connected to the main box by an additional connecting piece. During the disassembly and assembly of the second hinge seat, the corresponding connecting piece needs to be disassembled and assembled before the second hinge seat can be installed on the main box or removed from the main box. Therefore, it is inconvenient to disassemble and assemble the second hinge seat and the main box. For example, the second hinge seat and the main box are connected by bolts or screws.

[0056] An embodiment of the present application provides a refrigeration device. Figures 1 to 7 , including a main box 1, a cabinet door 4 and a hinge 5. The cabinet door 4 is rotatably connected to the main box 1 through a first hinge seat 2 and a second hinge seat 3.

[0057] The main box 1 has a accommodating cavity 121 and a loading and unloading port 6 connected to the accommodating cavity 121. The arrangement direction of the accommodating cavity 121 and the loading and unloading port 6 is a preset direction, and the accommodating cavity 121 is used to store materials. The cabinet door 4 is covered on the loading and unloading port 6. The hinge 5 includes a first hinge seat 2 and a second hinge seat 3 arranged on the first hinge seat 2. The first hinge seat 2 is connected to the cabinet door 4. The first hinge seat 2 at least partially rotates relative to the second hinge seat 3. The rotation center axis of the first hinge seat 2 relative to the second hinge seat 3 is the target axis 7. The connection between the second hinge seat 3 and the main box 1 is a snap connection.

[0058] It needs to be explained that the connection method between the second hinge seat 3 and the main box 1 is snap-fitting, which means that the second hinge seat 3 and the main box 1 are connected by snap-fitting, and there is no other connection method between the second hinge seat 3 and the main box 1 except snap-fitting.

[0059] In the embodiment of the present application, the connection between the second hinge seat 3 and the main box 1 is a snap-on connection. The second hinge seat 3 can be installed by snapping into the main box 1. The second hinge seat 3 can be pulled out from the main box 1 under the action of a large external force to thereby disassemble the second hinge seat 3. During the disassembly and assembly of the second hinge seat 3 and the main box 1, there is no need to disassemble additional connecting parts. Therefore, the disassembly and assembly between the second hinge seat 3 and the main box 1 is relatively convenient.

[0060] In one embodiment, please refer to Figure 1 to Figure 7 The main box 1 has a first mounting platform 131 and a second mounting platform 132. The second hinge seat 3 has a first clamping portion 31, a second clamping portion 32 and a clamping groove between the first clamping portion 31 and the second clamping portion 32. The first mounting platform 131 is located in the clamping groove. The first mounting platform 131 abuts against the outer side of the first clamping portion 31, and the second clamping portion 32 abuts against the outer side of the first mounting platform 131 and the inner side of the second mounting platform 132 respectively.

[0061] It should be explained that the direction toward the center of the accommodating cavity 121 is the inner direction, and the direction away from the center of the accommodating cavity 121 is the outer direction.

[0062] For example, see Figure 4 and Figure 7 The first hinge seat 2 includes a seat body 21 and a hinge shaft assembly. The seat body 21 and the second hinge seat 3 are both sleeved on the hinge shaft assembly so that the seat body 21 can rotate relative to the second hinge seat 3. The seat body 21 is connected to the cabinet door 4. The seat body 21 is an integrally formed structure, and the second hinge seat 3 is an integrally formed structure. The hinge shaft assembly is in the integrally formed seat body 21 and the integrally formed second hinge seat 3, and is shielded by the integrally formed seat body 21 and the integrally formed second hinge seat 3, thereby reducing the exposure of the hinge shaft assembly, eliminating the need to set an additional hinge cover, and reducing the number of parts.

[0063] For example, see Figure 4 and Figure 7 , the material of the seat body 21 is plastic.

[0064] For example, see Figure 4 and Figure 7 The hinge shaft assembly includes a retaining ring 22, a spring 34, a rotating shaft 35 and a converter 23. The rotating shaft 35 is rotatably connected with the second hinge seat 3. The rotating shaft 35 is inserted into the seat body 21. The spring 34 is sleeved on the rotating shaft 35. The spring 34 is located in the second hinge seat 3. The converter 23 is sleeved on the rotating shaft 35. The converter 23 can rotate relative to the rotating shaft 35. The converter 23 is located in the seat body 21. The seat body 21 rotates with the converter 23. The end of the spring 34 away from the seat body 21 abuts against the second hinge seat 3. The other end of the spring 34 abuts against the converter 23. The end of the converter 23 away from the spring 34 has an inclined surface that can abut against a part of the structure of the seat body 21, so that the elastic force of the spring 34 can be converted into the circumferential force of the converter 23, reducing the impact during the opening and closing process of the cabinet door 4. The retaining ring 22 is threadedly connected with the rotating shaft 35. The retaining ring 22 abuts against the end of the seat body 21 away from the second hinge seat 3 along the axial direction of the rotating shaft 35.

[0065] In the embodiment of the present application, the second hinge seat 3 is connected to the main box 1 by being clamped between the first clamping portion 31 and the second clamping portion 32. On the other hand, the inner side of the second mounting platform 132 abuts against the second clamping portion 32, that is, the outer side of the second clamping portion 32 is constrained by the second mounting platform 132 of the main box 1, which is beneficial to improving the connection strength of the second hinge seat 3 clamped on the main box 1.

[0066] In one embodiment, please refer to Figure 1 and Figure 2 The cavity wall of the accommodating cavity 121 that is arranged opposite to the access opening 6 is the target cavity wall 16 , and the second mounting platform 132 is located on a side of the first mounting platform 131 that points to the accommodating cavity 121 along the access opening 6 .

[0067] In the embodiment of the present application, the second mounting platform 132 can be positioned as close to the inside as possible according to actual needs without being affected by the first mounting platform 131 , which is helpful to reduce the degree of outward protrusion of the second hinge seat 132 .

[0068] In one embodiment, please refer to Figure 4 The second clamping part 32 includes a first sub-component 321, a transition part 323, and a second sub-component 322. The first sub-component 321 abuts against the outer side of the first mounting platform 131, and the arrangement direction of the first sub-component 321 and the first clamping part 31 is arranged crosswise with the preset direction. The transition part 323 is connected to the inner side of the first sub-component 321, and the rotation center axis of the first hinge seat 2 and the second hinge seat 3 is the target axis 7. The transition part 323 is located between the target axis 7 and the second mounting platform 132 along the preset direction. The second sub-component 322 is connected to the inner side of the transition part 323, and the second sub-component 322 abuts against the inner side of the second mounting platform 132.

[0069] In the embodiment of the present application, the second clamping portion 32 includes a first sub-component 321, a transition component 323 and a second sub-component 322. The first sub-component 321 abuts against the outer side of the first mounting platform 131 and the second sub-component 322 abuts against the inner side of the second mounting platform 132. The external forces acting on the two components are in opposite directions, thereby effectively abutting the second clamping portion 32 against the second mounting platform 132. The second sub-component 322 extends inward to abut against the second mounting platform 131, which helps to reduce the degree of outward protrusion of the second clamping portion 32.

[0070] It is understandable that the second clamping portion 32 is not limited to the above-mentioned curved shape. For example, when the second mounting platform 132 extends out of the main box 1, the second clamping portion 32 may also be straight.

[0071] In one embodiment, please refer to Figures 4 to 5The main box 1 is formed with a first accommodating groove 14, the transition piece 323 and the second sub-piece 322 are both located in the first accommodating groove 14, the first accommodating groove 14 has a first groove wall 141, the first groove wall 141 is located on the side of the first accommodating groove 14 facing the target axis 7, the first sub-piece 321 has a buckle 3211, the buckle 3211 is at least partially located on the side of the first groove wall 141 away from the target axis 7 so that the buckle 3211 is buckled with the first groove wall 141.

[0072] In the embodiment of the present application, the second sub-component 322 extends into the first receiving groove 14, and the first sub-component 321 has a buckle 3211, which is engaged with the side of the first groove wall 141 away from the target axis 7, so that the second clamping portion 32 can be more firmly installed in the first receiving groove 14.

[0073] It is understandable that the main box 1 is not limited to being provided with the first accommodating groove 14. For example, the main box 1 may not be provided with the first accommodating groove 14, and the first sub-component 321 may not be provided with the buckle 3211. The connection strength between the second hinge seat 3 and the main box 1 is only improved by the abutment between the second sub-component 322 and the second mounting platform 132.

[0074] In one embodiment, please refer to Figure 6 The number of the buckles 3211 is at least two, and at least two buckles 3211 are arranged at intervals along the target axis 7.

[0075] In the embodiment of the present application, at least two buckles 3211 are arranged at intervals along the target axis 7, which can ensure that the first sub-component 321 is connected to the first groove wall 141 more firmly, preventing the second clamping portion 32 from loosening under the action of external force when the first hinge seat 2 and the second hinge seat 3 rotate relative to each other.

[0076] Exemplarily, the number of the buckle 3211 may also be one.

[0077] In one embodiment, please refer to Figure 6 The second hinge seat 3 also has a rib plate 331. When the first hinge seat 2 rotates to a certain angle, the rib plate 331 abuts against the first hinge seat 2 to limit the first hinge seat 2 from further rotating, thereby limiting the rotation of the cabinet door 4 connected to the first hinge seat 2.

[0078] In one embodiment, the buckle 3211 is elastic.

[0079] In the embodiment of the present application, the buckle 3211 is elastic, which makes the installation and disassembly of the second hinge seat 3 more convenient and labor-saving, and is easy to disassemble and assemble.

[0080] Exemplarily, the buckle 3211 may also be a rigid structure.

[0081] In one embodiment, please refer to Figure 5The first receiving groove 14 has a second groove wall 142 , and the second groove wall 142 abuts against the inner side of the second sub-component 322 .

[0082] In the embodiment of the present application, the second groove wall 142 abuts against the inner side of the second sub-component 322, which can fix the second sub-component 322 between the second groove wall 142 and the second mounting platform 132 to prevent the second sub-component 322 from loosening, thereby making the second clamping portion 32 more firmly clamped.

[0083] It is understandable that the second sub-element 322 is not limited to the inner side thereof abutting against the second slot wall 142. Exemplarily, the second sub-element 322 is spaced apart from the second slot wall 142.

[0084] In one embodiment, please refer to Figures 4 to 5 The main box 1 is formed with a second accommodating groove 15 , the first clamping portion 31 is located in the second accommodating groove 15 , and the second accommodating groove 15 has a third groove wall 151 , which abuts against the inner side of the first clamping portion 31 .

[0085] In the embodiment of the present application, the third groove wall 151 abuts against the inner side of the first clamping portion 31 , so as to fix the first clamping portion 31 between the third groove wall 151 and the first mounting platform 131 , thereby preventing the first clamping portion 31 from loosening.

[0086] It is understandable that the installation method of the first mounting platform 131 is not limited. For example, the main box 1 may not be provided with the second receiving groove, or the third groove wall 151 and the first clamping portion 31 are arranged at intervals.

[0087] In one embodiment, please refer to Figures 1 to 3 The main box 1 includes an outer shell 11, an inner liner 12 and an opening frame 13. The inner liner 12 is located in the outer shell 11, and a receiving cavity 121 is formed in the inner liner 12. A heat-insulating cavity 17 is formed between the outer shell 11 and the inner liner 12; the opening of the heat-insulating cavity 17 is covered by the opening frame 13, and the opening frame 13 is connected to the outer shell 11 and the inner liner 12 respectively, and a first mounting platform 131 and a second mounting platform 132 are formed in the opening frame 13.

[0088] In the embodiment of the present application, the second hinge seat 3 is installed on the mouth frame 13, which can facilitate the installation and disassembly of the hinge seat and can also effectively extend the service life of the refrigeration equipment.

[0089] For example, the first receiving groove 14 and the second receiving groove 15 are also formed on the mouth frame 13.

[0090] It is understandable that the first mounting platform 131 and the second mounting platform 132 are not limited to being arranged on the mouth frame 13. Exemplarily, the first mounting platform 131 and the second mounting platform 132 can also be arranged on the housing 11. Exemplarily, one of the first mounting platform 131 and the second mounting platform 132 is arranged on the housing 11, and the other of the first mounting platform 131 and the second mounting platform 132 is arranged on the mouth frame 13.

[0091] In one embodiment, please refer to Figure 4 The cabinet door 4 and the main box 1 are arranged to form an inwardly recessed avoidance cavity 18 , and the first hinge seat 2 and the second hinge seat 3 are at least partially located in the avoidance cavity 18 .

[0092] In the embodiment of the present application, an avoidance cavity 18 is provided in the cabinet door 4 and the main box 1, so that the first hinge seat 2 and the second hinge seat 3 are partially located in the avoidance cavity 18, which can reduce the protruding height of the hinge and effectively save space.

[0093] It is understandable that the cabinet door 4 and the main box 1 are not limited to enclosing the avoidance cavity 18. Exemplarily, the avoidance cavity 18 may not be provided, and the first hinge seat 2 and the second hinge seat 3 are provided on the housing 11 of the main box 1.

[0094] In one embodiment, please refer to Figure 1 to Figure 3 , Fig.10 and Fig.16 , the cabinet door 4 is located above the main box 1, and the target axis 7 is arranged to cross the up-down direction.

[0095] In one embodiment, please refer to Figure 8 to Figure 15 The main box 1 has an installation cavity 82 and a stop platform 81, the installation cavity 82 includes a main cavity 821 and a limit cavity 822 that are interconnected, the arrangement direction of the main cavity 821 and the limit cavity 822 is a first direction, the arrangement direction of the limit cavity 822 and the stop platform 81 is a second direction, and the second direction is arranged crosswise with the first direction; the hinge 5 has a limit portion 86, the size of the installation cavity 82 along the first direction is set so that the limit portion 86 can be moved from the first direction to the limit portion 86 along the first direction The main cavity 821 moves to the limiting cavity 822. When the limiting portion 86 is offset from the stop platform 81, the second hinge seat can move into or out of the main cavity 821 along the second direction. When the limiting portion 86 is at least partially located in the limiting cavity 822, projected along the second direction, the projection area of ​​the limiting portion 86 and the projection area of ​​the stop platform 81 at least partially overlap, so as to limit the limiting portion 86 from leaving the limiting cavity 822 along the second direction toward one side of the stop platform 81.

[0096] In the embodiment of the present application, the size of the installation cavity 82 along the first direction is set to enable the limit portion 86 to move from the main cavity 821 to the limit cavity 822 along the first direction. When the limit portion 86 is staggered from the stop platform 81, the hinge 5 can be moved into the installation cavity 82 from the second direction.
