[0043] See also Figures 1 to 7The present application provides a refrigeration device, which may include: a door body 200, a storage rack 400 and a limiting mechanism 300. The storage rack 400 may be arranged at the rear of the door body 200. The two sides of the storage rack 400 may be recessed with a snap-fitting groove 410. The limiting mechanism 300 may be accommodated in the door body 200, and the limiting mechanism 300 may be located on at least one side of the door body 200. The limiting mechanism 300 may include a hinge rod 310, a first rotating rod 320 and a second rotating rod 330. One end of the hinge rod 310 is rotatably connected to the door body 200, and the other end of the hinge rod 310 is rotatably connected to the first rotating rod 320. A toggle portion 322 may be convexly provided on the first rotating rod 320. The toggle portion 322 may pass through the rear end wall of the door body 200. The toggle portion 322 can drive the first rotating rod 320 to rotate relative to the hinge rod 310. The second rotating rod 330 is rotatably connected to the door body 200. One end of the second rotating rod 330 is rotatably connected to the first rotating rod 320, and the other end of the second rotating rod 330 can pass through the door body 200, and the other end of the second rotating rod 330 is detachably engaged in the engaging groove 410.

[0044] When the storage rack 400 is installed on the door body 200, the user can move the toggle portion 322 to rotate the first rotating rod 320 around the hinge rod 310, and the hinge rod 310 rotates relative to the door body 200. The first rotating rod 320 drives the second rotating rod 330 to rotate, so that the second rotating rod 330 moves toward the outside of the door body 200.

[0045] Then, the storage rack 400 is moved onto the door body 200 so that the engaging groove 410 is arranged opposite to the limiting mechanism 300. The user moves the toggle portion 322 again so that the first rotating rod 320 rotates around the hinge rod 310, and the hinge rod 310 rotates relative to the door body 200. The first rotating rod 320 drives the second rotating rod 330 to rotate so that the second rotating rod 330 moves toward the storage rack 400, and the second rotating rod 330 extends into the engaging groove 410, and the second rotating rod 330 is limited to the storage rack 400. In this way, the storage rack 400 is quickly limited on the door body 200, thereby improving the installation efficiency of the storage rack 400 and reducing the installation cost.

[0046] When the storage rack 400 needs to be disassembled, the user moves the toggle portion 322 to rotate the first rotating rod 320 around the hinge rod 310, and the hinge rod 310 rotates relative to the door body 200. The first rotating rod 320 drives the second rotating rod 330 to rotate, so that the second rotating rod 330 moves toward the outside of the door body 200. The second rotating rod 330 escapes from the engaging groove 410, and the second rotating rod 330 is separated from the storage rack 400. This improves the disassembly efficiency of the storage rack 400, and facilitates the replacement, cleaning and maintenance of the storage rack 400.

[0047] See also Figures 2 to 4In this embodiment, a snap-fitting groove 410 may be provided on the side wall of the storage rack 400. The storage rack 400 is limited by the snap-fitting groove 410 with the door shelf so that the storage rack 400 is installed on the door body 200.

[0049] In other embodiments, at least one side of the storage rack 400 can be supported on the door body 200 to limit the position of the door body 200. This further improves the connection strength between the storage rack 400 and the door body 200, and ensures the stability and reliability of the storage rack 400.

[0050] See also Figures 1 to 3 , Figures 5 to 7 In this embodiment, the refrigeration device may include a door body 200. The door body 200 is rotatably connected to the cabinet body 100.

[0051] A foaming space may be provided in the door body 200. The foaming space is used to accommodate the limiting mechanism 300. On the one hand, the door body 200 can protect the limiting mechanism 300 and prevent the user from accidentally touching or damaging the limiting mechanism 300. On the other hand, the space occupancy rate of the limiting mechanism 300 can be effectively reduced, the space utilization rate of the door body 200 can be improved, and the volume of the door body 200 can be effectively reduced; the appearance of the door body 200 can also be optimized.

[0052] In some embodiments, a foaming layer may be provided in the foaming space, and the foaming layer may be attached to the inner wall of the door body 200. The foaming layer is formed by foaming a foaming material to improve the heat preservation, structural strength and reliability of the door body 200.

[0053] See also Figure 3 , Figure 5 and Figure 7 In this embodiment, the rear end wall of the door body 200 may be provided with a moving hole 220 relative to the toggle portion 322. The toggle portion 322 can move in the moving hole 220. The toggle portion 322 moves in the moving hole 220. When the toggle portion 322 is located at one end of the moving hole 220, the storage rack 400 can be limited on the door body 200. When the toggle portion 322 is located at the other end of the moving hole 220, the storage rack 400 can be separated from the door body 200 to disassemble the storage rack 400.

[0054] See also Figures 3 to 6 In this embodiment, the door body 200 may have two accommodating protrusions 230 extending backward. The two accommodating protrusions 230 may be located on both sides of the storage rack 400, respectively.

[0055] In some embodiments, one accommodating protrusion 230 can be abutted against a side wall of the storage rack 400 , and another accommodating protrusion 230 is spaced apart from another side wall of the storage rack 400 .

[0056] In other embodiments, the accommodating protrusions 230 can be supported against two side walls of the storage rack 400 to improve the connection strength between the storage rack 400 and the door body 200 .

[0057] See also Figure 7 In this embodiment, the accommodating protrusion 230 is hollow to communicate with the foaming space. The accommodating protrusion 230 can accommodate the limiting mechanism 300. A locking through hole 232 can be opened on a side wall of the accommodating protrusion 230 close to the storage rack 400. The second rotating rod 330 is located in the accommodating protrusion 230, and one end of the second rotating rod 330 can pass through the locking through hole 232 to limit the storage rack 400. Thereby, the storage rack 400 is limited on the door body 200.

[0058] When the storage rack 400 is installed on the door body 200, the second rotating rod 330 rotates in the receiving protrusion 230, so that one end of the second rotating rod 330 can be limited by the engaging groove 410 through the engaging through hole 232. Thus, the storage rack 400 is limited on the receiving protrusion 230, and the installation efficiency of the storage rack 400 is improved.

[0059] When the storage rack 400 is disassembled from the door body 200, the second rotating rod 330 rotates in the accommodating protrusion 230, so that one end of the second rotating rod 330 can move away from the storage rack 400 in the engaging through hole 232. Thus, the storage rack 400 is separated from the second rotating rod 330, and the user can disassemble the storage rack 400, thereby improving the disassembly efficiency of the storage rack 400 and facilitating the replacement, cleaning and maintenance of the storage rack 400.

[0060] Figure 8 It is a structural schematic diagram of the rotating box and the limiting mechanism of the utility model. Fig. 9 yes Figure 8 A cross-sectional view of the structure shown in .

[0061] See also Figures 6 to 9 In this embodiment, the door body 200 may include a rotating box 240. The rotating box 240 may be disposed in the door body 200. The rotating box 240 may be attached to the rear end wall of the door body 200 to facilitate the arrangement of the toggle portion 322. The hinge rod 310, the first rotating rod 320, and the second rotating rod 330 may all be located in the rotating box 240. Thus, the limiting mechanism 300 can be protected, so that the limiting mechanism 300 can operate safely and stably.

[0062] The rotating box 240 may be provided with a first through hole 242 relative to the toggle portion 322, and the toggle portion 322 may be movable in the first through hole 242. The rotating box 240 may be provided with a second through hole 245 relative to the engaging groove 410, and the second rotating rod 330 may be engaged with the storage rack 400 through the second through hole 245 for limiting. The toggle portion 322 may extend out of the door body 200 after passing through the first through hole 242 and the moving hole 220, so that the user can move the toggle portion 322. The second rotating rod 330 may extend out of the door body 200 after passing through the second through hole 245 and the engaging through hole 232, so that the storage rack 400 can be installed and removed.

[0063] See also Figures 6 to 9 In this embodiment, the rotating box 240 may include a first rotating portion 241 and a second rotating portion 244. The first rotating portion 241 may be located on a side of the second rotating portion 244 close to the center of the door body 200. The space of the first rotating portion 241 may be connected to the space in the second rotating portion 244. The first rotating portion 241 may be attached to the rear end wall of the door body 200. The first rotating rod 320 may be accommodated in the first rotating portion 241. The first through hole 242 may be provided on the rear end wall of the first rotating portion 241 to facilitate the arrangement and movement of the toggle portion 322. The second rotating portion 244 may be attached to a side wall of the accommodating protrusion 230 close to the storage rack 400. The second rotating portion 244 may accommodate the second rotating rod 330. The second through hole 245 may be provided on the second rotating portion 244 to facilitate the engagement and separation of the second rotating rod 330 with the storage rack 400.

[0064] In some embodiments, the first rotating portion 241 may extend in the left-right direction. The second rotating portion 244 may extend in the front-back direction. The first rotating portion 241 may be located on a side of the second rotating portion 244 close to the center of the door body 200 to reduce the volume of the door body 200 and improve the space utilization of the door body 200.

[0065] In some embodiments, the first rotating portion 241 and the second rotating portion 244 may have an arc transition, and the rear end wall of the door body 200 and the accommodating protrusion 230 may have an arc transition, so that the rotating box 240 can fit the inner wall of the door body 200. On the one hand, the structural strength of the door body 200 and the rotating box 240 can be improved. On the other hand, the foaming layer is prevented from extending between the rotating box 240 and the rear end wall of the door body 200, thereby improving the safety and stability of the rotating box 240.

[0066] In some embodiments, the first rotating portion 241 may be attached to the rear end wall of the door body 200. The second rotating portion 244 extends backward to pass through the rear end wall of the door body 200. The second rotating portion 244 can directly limit the storage rack 400 to limit the storage rack 400 to the rotating box 240.

[0067] Fig.10 It is a structural schematic diagram of the limit mechanism and part of the rotating box of the utility model.

[0068] See also Figures 8 to 10 In this embodiment, the rotating box 240 may be provided with an elastic stopper in the first through hole 242 . The elastic stopper can abut against the toggle portion 322 to limit the movement of the toggle portion 322 in the first through hole 242 .

[0069] In some embodiments, the first through hole 242 can extend in the left-right direction, and the toggle portion 322 can move in the left-right direction in the first through hole 242. The elastic stopper can extend in the left-right direction. One end of the elastic stopper is connected to a side wall of the first through hole 242, and the other end of the elastic stopper is spaced from the other side wall of the first through hole 242 so that the other end of the elastic stopper can bounce in the up-down direction.

[0070] The elastic limiting member can limit the toggle portion 322 to one side of the first through hole 242, thereby ensuring the stability of the limiting mechanism 300. The user can apply external force to the toggle portion 322 so that the toggle portion 322 can squeeze the elastic limiting member, so that the toggle portion 322 can move to the other side of the first through hole 242, thereby driving the limiting mechanism 300 to rotate and switching the connection state between the storage rack 400 and the limiting mechanism 300 and the door body 200.

[0071] In other embodiments, one end of the elastic limiting member is connected to a side of the first through hole 242 close to the center of the door body 200 , and the other end of the first limiting member extends in a direction away from the center of the door body 200 .

[0072] In other embodiments, in a direction away from the center of the door body 200 , the elastic limiting member is arranged obliquely close to the toggle portion 322 , so that the end of the elastic limiting member can limit the toggle portion 322 .

[0073] In other embodiments, two elastic stoppers may be disposed in the first through hole 242. The two elastic stoppers are arranged at intervals in the up-down direction. On the one hand, the two elastic stoppers can more stably stop the toggle portion 322 at one side of the first through hole 242. On the other hand, the two elastic stoppers can move in opposite directions under the action of an external force, thereby facilitating the toggle portion 322 to move between the two elastic stoppers.

[0074] In some embodiments, the elastic limiting member may be protruded from the upper surface and / or the lower surface of the first through hole 242 to limit the movement of the toggle portion 322 in the left-right direction.

[0075] See also Figure 7 , Figures 9 and 10In this embodiment, the door body 200 may be formed with a stop rib 246 protruding relative to the second rotating rod 330 , and the stop rib 246 may be able to resist the second rotating rod 330 to limit the rotation angle of the second rotating rod 330 .

[0076] In some embodiments, the stop rib 246 may be disposed in the rotating box 240. The stopper may be disposed on a side wall of the second rotating portion 244 close to the storage rack 400. This can limit the rotation angle of the second rotating rod 330 and prevent the second rotating rod 330 from rotating too much and hitting the side wall of the working box, thereby ensuring the reliability and stability of the limiting mechanism 300.

[0077] In other embodiments, the stop rib 246 can be disposed on the second rotating rod 330. The stop rib 246 can abut against the rotating box 240 to limit the rotation angle of the second rotating rod 330.

The toggle portion 322 can move in the left-right direction to drive the first rotating rod 320 to rotate.

[0083] See also Figure 7 , Figures 9 to 11 In this embodiment, the middle part of the first rotating rod 320 is rotatably connected to the hinge rod 310. The first rotating rod 320 is located at the front side of the hinge rod 310. A toggle portion 322 is provided at one end of the first rotating rod 320, and the other end of the first rotating rod 320 is rotatably connected to the second rotating rod 330. The provision of the hinge rod 310 enables the first rotating rod and the second rotating rod 330 to rotate relative to each other, prevents the first rotating rod 320 and the second rotating rod 330 from interfering with each other, and ensures the stable operation of the limiting mechanism 300.

[0084] See also Figure 5 , Figure 7 , Figures 9 to 11 In this embodiment, one end of the first rotating rod 320 away from the second rotating rod 330 may be protruded to form an extension portion 321. The extension portion 321 may extend downward to exceed the lower portion of the storage rack 400. The lower portion of the extension portion 321 may be connected to a toggle portion 322. This allows the user to quickly and conveniently move the toggle portion 322, preventing the storage rack 400 from affecting the user's adjustment of the toggle portion 322.

[0085] In some embodiments, the rear end of the toggle portion 322 can also extend in the left-right direction to facilitate the user's holding and toggling.

[0086] See also Figure 5 , Figure 7 , Figures 9 to 11 In this embodiment, the second rotating rod 330 is rotatably connected to the second rotating portion 244. The second rotating rod 330 extends in the front-to-back direction. The second rotating rod 330 may be located on a side of the first rotating rod 320 away from the center of the storage rack 400. The second rotating rod 330 may extend in the front-to-back direction. The front end of the second rotating rod 330 is rotatably connected to the first rotating rod 320, and the rear end of the second rotating rod 330 can pass through the door body 200.

[0087] In some embodiments, the rear end of the second rotating rod 330 can rotate toward the storage rack 400 to pass through the rotating box 240 and the accommodating protrusion 230 so that the rear end of the second rotating rod 330 can be engaged with the engaging groove 410 of the storage rack 400 .

[0088] See also Figure 5, Figures 7 to 11 In this embodiment, the rear end of the second rotating rod 330 may protrude relative to the engaging through hole 232 to form an engaging portion 331. The engaging portion 331 can rotate toward the storage rack 400 to engage with the engaging groove 410 through the engaging through hole 232 to limit the storage rack 400 on the door body 200.

[0089] In some embodiments, the end of the second rotating rod 330 away from the first rotating rod 320 is tilted toward the storage rack 400. The second rotating rod 330 only needs to rotate a small angle to achieve the engagement of the engaging portion 331 with the storage rack 400, thereby improving the installation efficiency and disassembly efficiency of the storage rack 400 and the door body 200.

[0090] See also Figure 7 In this embodiment, the limiting mechanism 300 and the rotating box 240 are disposed in the rotating box 240 on one side.

[0091] When the limiting mechanism 300 moves from the engaged state to the disassembled state to disassemble the storage rack 400, the user applies force to the toggle portion 322 to move the toggle portion 322 toward the center of the door body 200. Under the action of the external force, the toggle portion 322 presses the elastic limiting rib 243 and moves to the side of the first through hole 242 close to the center of the door body 200.

[0092] When the toggle portion 322 moves toward the center of the door body 200, the first rotating rod 320 moves toward the center of the door body 200. During the movement of the first rotating rod 320, the first rotating rod 320 also rotates backward around the hinge rod 310 to drive the hinge rod 310 to rotate backward relative to the rear end wall of the rotating box 240. As a result, the front end of the second rotating rod 330 is driven to rotate toward the center of the door body 200, and the rear end of the second rotating rod 330 is driven to rotate away from the center of the door body 200. The rear end of the second rotating rod 330 is disengaged from the engaging groove 410, the limiting mechanism 300 is in a disassembled state, and the storage rack 400 is separated from the door body 200.

[0093] When the limiting mechanism 300 moves from the disassembled state to the engaged state to install the storage rack 400, the user applies force to the toggle portion 322 to move the toggle portion 322 away from the center of the door body 200. The toggle portion 322 presses the elastic limiting rib 243 under the action of the external force and moves to the right side of the first through hole 242.

[0094] When the toggle portion 322 moves away from the center of the door body 200, the elastic stopper moves away from the center of the door body 200. During the movement of the first rotating rod 320, the first rotating rod 320 also rotates forward around the hinge rod 310 to drive the hinge rod 310 to rotate forward relative to the rear end wall of the rotating box 240. As a result, the front end of the second rotating rod 330 is driven to rotate away from the center of the door body 200, and the rear end of the second rotating rod 330 rotates toward the center of the door body 200. The rear end of the second rotating rod 330 is engaged in the engaging groove 410, the limiting mechanism 300 is in an engaged state, and the storage rack 400 is limited on the door body 200.

[0095] See also Figure 5 and Figure 6 In this embodiment, the door body 200 extends backward to form two accommodating protrusions 230. The accommodating protrusion 230 on one side contains a limiting mechanism 300. It can limit one side of the storage rack 400. The accommodating protrusion 230 on the other side is provided with a fixed block 231. The fixed block 231 is adapted to the engaging groove 410 on the other side of the storage rack 400 to limit the other side of the storage rack 400. The fixed block 231 and the engaging portion 331 can jointly limit the storage rack 400 on the door body 200.

[0096] When the storage rack 400 is disassembled, the user moves the toggle portion 322 to drive the first rotating rod 320, the hinge rod 310 and the second rotating rod 330 to rotate, so that the engaging portion 331 escapes from the engaging groove 410. Then the storage rack 400 is moved to separate the fixed block 231 from the storage rack 400, thereby disassembling the storage rack 400.

[0097] In some embodiments, the door body 200 is formed with two accommodating protrusions 230 extending backwards. The two accommodating protrusions 230 accommodate the limiting mechanism 300. The two second rotating rods 330 can limit the two sides of the storage rack 400 to limit the storage rack 400 on the door body 200.

[0098] When the storage rack 400 is disassembled, the two toggle parts 322 are moved simultaneously or sequentially to move toward each other. The two engaging parts 331 move away from each other to escape from the engaging grooves 410 on both sides of the storage rack 400. The limiting mechanism 300 is in a disassembled state, so that the storage rack 400 is separated from the door body 200.

[0099] In other embodiments, the rotating box 240 extends in the left-right direction, and the rotating box 240 opens at one end toward the rear end wall of the door body 200. The rotating box 240 is detachably covered on the rear end wall of the door body 200. The limiting mechanism 300 is accommodated in the rotating box 240, so that the rotating box 240 can protect the limiting mechanism 300. The rotating box 240 can also prevent the foaming layer from extending into the rotating box 240.

[0100] In some embodiments, the limiting mechanism 300 may include a hinge rod 310 , a first rotating rod 320 , and a second rotating rod 330 . The hinge rod 310 , the first rotating rod 320 , and the second rotating rod 330 are all located in the accommodating protrusion 230 .

[0101] The hinge rod 310 can extend in the left-right direction. One end of the hinge rod 310 is rotatably connected to the side wall of the accommodating protrusion 230. The other end of the hinge rod 310 is rotatably connected to the first rotating rod 320. The first rotating rod 320 can extend in the up-down direction. The lower end of the first rotating rod 320 can be provided with a toggle portion 322. The toggle portion 322 can pass through the accommodating protrusion 230. The second rotating rod 330 can be located on the upper side of the first rotating rod 320. The middle part of the second rotating rod 330 is rotatably connected to the accommodating protrusion 230. The lower end of the second rotating rod 330 can be rotatably connected to the upper end of the first rotating rod 320. The upper end of the second rotating rod 330 is provided with a clamping portion 331 protruding toward the center of the door body 200. The clamping portion 331 can pass through a side wall of the accommodating protrusion 230 close to the center of the door body 200. The engaging portion 331 can be engaged with the engaging groove 410 of the storage rack 400 to restrict the storage rack 400 to be located on the door body 200 .

[0102] When the storage rack 400 is installed on the door body 200, the toggle portion 322 is moved upward or downward, so that the first rotating rod 320 rotates around the hinge rod 310, and the hinge rod 310 rotates around the accommodating protrusion 230. Thus, the engaging portion 331 of the second rotating rod 330 moves toward the storage rack 400 and is engaged in the storage rack 400.

[0103] When the storage rack 400 is detached from the door body 200, the toggle portion 322 is moved downward or upward, so that the first rotating rod 320 rotates around the hinge rod 310, and the hinge rod 310 rotates around the accommodating protrusion 230. As a result, the engaging portion 331 of the second rotating rod 330 moves away from the storage rack 400, and the engaging portion 331 escapes from the engaging groove 410. The user can quickly detach the storage rack 400.

[0104] See also Figures 1 to 11 In the present invention, when the storage rack 400 is installed on the door body 200, the user first moves the toggle portion 322 to switch the limiting mechanism 300 to the disassembly state, and the engaging portion 331 is accommodated in the accommodating protrusion 230. Then the storage rack 400 is moved onto the door body 200 so that the engaging groove 410 is arranged opposite to the limiting mechanism 300.

[0105] The user then moves the toggle portion 322 to switch the limiting structure from the disassembly state to the engagement state, and the engagement portion 331 moves toward the storage rack 400. The engagement portion 331 can be engaged and limited on the storage rack 400 to limit the storage rack 400 on the door body 200. Thus, the storage rack 400 and the door body 200 can be quickly installed, thereby improving the installation efficiency of the storage rack 400.

[0106] When the storage rack 400 is removed from the door body 200, the user moves the toggle portion 322 to switch the limiting mechanism 300 from the engaged state to the disassembled state. The engaging portion 331 moves in a direction away from the storage rack 400 and is accommodated in the accommodating protrusion 230. This allows the user to remove the storage rack 400 from the door body 200. This can effectively improve the disassembly efficiency of the storage rack 400.

[0107] In the present application, when the storage rack 400 is installed on the door body 200, the first rotating rod 320 is driven to rotate around the hinge rod 310 by moving the toggle part 322, and the hinge rod 310 rotates relative to the door body 200. The first rotating rod 320 rotates to drive the second rotating rod 330 to rotate, so that the second rotating rod 330 moves toward the outside of the door body 200. Then the storage rack 400 is moved onto the door body 200, and the toggle part 322 is moved to move the second rotating rod 330 toward the storage rack 400. The second rotating rod 330 extends into and engages in the engaging groove 410 to limit the storage rack 400 on the door body 200. When the storage rack 400 needs to be disassembled, the toggle part 322 is moved to move the second rotating rod 330 toward the outside of the door body 200, and the second rotating rod 330 escapes from the engaging groove 410, and the storage rack 400 is separated from the door body 200. The refrigeration device of the present application can facilitate the installation and disassembly of the storage rack 400, thereby improving the installation and disassembly efficiency of the storage rack 400.
