Detailed Implementation

[0038] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0039] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In existing refrigeration equipment, the fixed height of the existing cabinet makes it difficult to position the cabinet during installation, and the installation of the cabinet is time-consuming and labor-intensive. Furthermore, the inability to adjust the height increases maintenance costs when the cabinet is moved or maintained later.

[0042] For ease of description, unless otherwise specified, the directions of up, down, left, right, front, and back in this article are based on the state of the refrigeration equipment when it is in use. The direction in which the refrigeration equipment faces the user is the front direction, and the direction in which it faces away from the user is the back direction. The vertical direction is up and down, and the horizontal direction is left and right.

[0043] Please see Figure 1 As shown, in some embodiments, the refrigeration device provided by this utility model may include a housing 1. The housing 1 may have a rectangular hollow structure. The internal space of the housing 1 may be used to provide storage space. The housing 1 may be constructed as the outer shell of the refrigeration device.

[0044] It should be noted that in some other embodiments, the box 1 may also be a hollow structure of other shapes.

[0045] Please see Figure 2 As shown, in some embodiments, a refrigeration space 20 may be provided inside the housing 1. The refrigeration space 20 can store food.

[0046] In some embodiments, the refrigeration space 20 may be provided in multiple sections. The multiple refrigeration spaces 20 may be arranged vertically or horizontally. Each refrigeration space 20, which is separated from the others, may serve as an independent storage space, such as a freezer, a refrigerator, or a variable temperature compartment, to meet different refrigeration needs such as freezing, refrigeration, and variable temperature storage according to different types of food.

[0047] Please see Figure 1 As shown, in some embodiments, a door 11 may be provided on the front side of the housing 1. The door 11 can be used to open and close the cooling space 20. The door 11 and the housing 1 can be connected by a hinge, so that the door 11 can rotate around the axis of the hinge to realize the opening and closing of the door 11, thereby opening and closing the corresponding cooling space 20.

[0048] It is understandable that multiple doors 11 can be set, each corresponding to a cooling space 20. Alternatively, multiple doors 11 can be opened and closed simultaneously in a single cooling space 20.

[0049] Please see Figure 2 As shown, in some embodiments, a liner 2 may be provided inside the housing 1. A cooling space 20 may be formed inside the liner 2.

[0050] It should be noted that multiple cooling chambers 2 can be installed. Within the same cooling chamber 2, there can be only one cooling space 20, or multiple cooling spaces 20 can be installed.

[0051] In some embodiments, the refrigeration device may include a refrigeration assembly (not shown). The refrigeration assembly may be located inside the housing 1. The refrigeration assembly is used to provide cooling to the interior of the refrigeration device to maintain a low-temperature environment within each refrigerated space 20.

[0052] In some embodiments, the refrigeration assembly may include a compressor (not shown). The compressor can compress the refrigerant, turning it into a high-temperature, high-pressure refrigerant vapor.

[0053] In some embodiments, the refrigeration assembly may include a condenser (not shown in the figure). The condenser can condense high-temperature, high-pressure refrigerant vapor into medium-temperature, medium-pressure liquid refrigerant.

[0054] In some embodiments, the condenser assembly may include a throttling device (not shown in the figures). The throttling device can be used to reduce the pressure of a medium-temperature, medium-pressure liquid refrigerant, thereby converting the medium-temperature, medium-pressure liquid refrigerant into a low-temperature, low-pressure refrigerant vapor.

[0055] In some embodiments, the refrigerant assembly may include an evaporator (not shown). The evaporator can evaporate and boil low-temperature, low-pressure refrigerant vapor to absorb heat from the surrounding medium.

[0056] In some embodiments, the refrigerant assembly may include refrigeration components such as a compressor, condenser, throttling device, and evaporator. After being compressed by the compressor, the refrigerant forms high-temperature, high-pressure refrigerant vapor. This high-temperature, high-pressure refrigerant flows into the condenser and is condensed into medium-temperature, high-pressure liquid refrigerant. After exiting the condenser, the medium-temperature, high-pressure liquid refrigerant can flow into the evaporator through the throttling device. The throttling device can reduce the pressure of the medium-temperature, high-pressure liquid refrigerant, transforming it into low-temperature, low-pressure refrigerant vapor. When the low-temperature, low-pressure refrigerant vapor enters the evaporator, it evaporates and boils, absorbing heat from the surrounding medium, thereby cooling the refrigeration space 20.

[0057] In some embodiments, the refrigeration unit can be embedded inside a cabinet. Specifically, the unit 1 can be embedded into the cabinet through an opening, thereby improving space utilization and simplifying the interior design.

[0058] Please see Figure 2 and Figure 3 As shown, in some embodiments, an installation space 12 may be provided below the bottom surface of the housing 1. The installation space 12 may be located above the ground.

[0059] Please see Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration equipment may include a height adjustment device 3. The height adjustment device 3 may be located within the installation space 12. The bottom surface of the height adjustment device 3 may be supported on the ground, and the top surface of the height adjustment device 3 may be supported on the bottom surface of the cabinet 1. The height adjustment device 3 is capable of adjusting its own height. Therefore, the height adjustment device 3 can be used to adjust the distance between the cabinet 1 and the ground, thereby raising or lowering the cabinet 1 to adjust its height. When the cabinet 1 is installed inside a cabinet, the height of the cabinet 1 inside the cabinet can be adjusted by the height adjustment device 3, allowing the cabinet 1 to fit perfectly with the cabinet, achieving efficient space utilization and visual integrity.

[0060] In some embodiments, two height adjustment devices 3 may be provided. The two height adjustment devices 3 may be located at the left and right ends of the installation space 12. Thus, the two height adjustment devices 3 can adjust the height of the left and right ends of the box 1, thereby preventing the height of the left and right ends of the box 1 from becoming unbalanced.

[0061] It should be noted that in some other embodiments, three or more height adjustment devices 3 may be provided. Multiple height adjustment devices 3 may be located at any position in the installation space 12.

[0062] Please see Figure 2 and Figure 3 As shown, in some embodiments, a cover plate is provided on the front side of the mounting space 12. The cover plate can cover the front opening of the mounting space 12. Thus, the cover plate can be exposed on the front side of the mounting space 12 as the front exterior surface, thereby improving the aesthetic appearance of the box.

[0063] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a connecting plate 31. The connecting plate 31 may be connected to the bottom surface of the housing 1. The connecting plate 31 may be plate-shaped. The connecting plate 31 may extend along the front-rear direction of the housing 1. The top surface of the connecting plate 31 may be connected to the bottom surface of the housing 1.

[0064] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a lead screw 32. The lead screw 32 is rotatably mounted on the connecting plate 31. The extension direction of the lead screw 32 is the same as the length direction of the connecting plate 31, that is, the lead screw 32 extends along the front-rear direction of the housing 1. Both ends of the lead screw 32 pass through the front and rear end faces of the connecting plate 31. The front end of the lead screw 32 passes through the front face of the connecting plate 31, and the front end of the lead screw 32 is provided with a first threaded section 321. The rear end of the lead screw 32 passes through the rear face of the connecting plate 31, and the rear end of the lead screw 32 is provided with a second threaded section 322.

[0065] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a first slider 33. The first slider 33 may be disposed on the lead screw 32. The first slider 33 may be threadedly connected to the first threaded section 321. The first slider 33 is capable of sliding back and forth along the first threaded section 321.

[0066] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a second slider 34. The second slider 34 may be disposed on the lead screw 32. The second slider 34 may be threadedly connected to the second threaded section 322. The second slider 34 is capable of sliding back and forth along the second threaded section 322.

[0067] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a base 35. The base 35 may be disposed below the bottom surface of the connecting plate 31. The bottom surface of the base 35 may be used to support the ground.

[0068] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a first support rod 36. The upper end of the first support rod 36 may be rotatably connected to the first sliding member 33. The lower end of the first support rod 36 may be rotatably connected to the base 35. Thus, when the first sliding member 33 slides along the axial direction of the lead screw 32, the first sliding member 33 can drive the upper end of the first support rod 36 to slide, causing the first support rod 36 to perform circular motion with its lower end as the center.

[0069] In some embodiments, the upper end of the first support rod 36 may be arranged at an angle away from the connecting plate 31.

[0070] It should be noted that in some other embodiments, the upper end of the first support rod 36 may be arranged at an angle toward the connecting plate 31.

[0071] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a second support rod 37. The upper end of the second support rod 37 may be rotatably connected to the second sliding member 34. The lower end of the second support rod 37 may be rotatably connected to the base 35. The upper end of the second support rod 37 is inclined away from the connecting plate 31. Thus, when the second sliding member 34 slides along the axial direction of the lead screw 32, the second sliding member 34 can drive the upper end of the second support rod 37 to slide, causing the second support rod 37 to perform circular motion with its lower end as the center.

[0072] In some embodiments, the upper end of the second support rod 37 may be arranged at an angle away from the connecting plate 31.

[0073] It should be noted that in some other embodiments, the upper end of the second support rod 37 may be arranged at an angle toward the connecting plate 31.

[0074] Please see Figure 6 and Figure 7 As shown, in some embodiments, when the lead screw 32 rotates in the forward direction, the first sliding member 33 and the second sliding member 34 move closer to each other, causing the upper end of the first support rod 36 to rotate towards the connecting plate 31, and the upper end of the second support rod 37 to rotate towards the connecting plate 31. Since the lower ends of the first support rod 36 and the second support rod 37 do not move, the height of the connecting plate 31 relative to the base 35 can be increased by using the first support rod 36 and the second support rod 37. When the lead screw 32 rotates in the reverse direction, the first sliding member 33 and the second sliding member 34 move away from each other, causing the upper end of the first support rod 36 to rotate away from the connecting plate 31, and the upper end of the second support rod 37 to rotate away from the connecting plate 31. Since the lower ends of the first support rod 36 and the second support rod 37 do not move, the height of the connecting plate 31 relative to the base 35 can be decreased by using the first support rod 36 and the second support rod 37. This allows the height of the enclosure 1 relative to the ground to be adjusted, enabling the enclosure 1 to adapt to different installation environments, improving the installation efficiency of the enclosure 1, and reducing subsequent maintenance costs.

[0075] Please see Figure 4 and Figure 5 As shown, in some embodiments, the height adjustment device 3 may include a first limiting member 38. The first limiting member 38 may be disposed at one end of the lead screw 32. The first limiting member 38 may be disposed at the end of the first threaded section 321 away from the second threaded section 322. The first limiting member 38 may abut against the end of the first sliding member 33 away from the second sliding member 34, and the first limiting member 38 can limit the first sliding member 33. Specifically, when the lead screw 32 rotates in the forward or reverse direction, the first sliding member 33 can slide between the first limiting member 38 and the front end face of the connecting plate 31.

[0076] Please see Figure 4 and Figure 5As shown, in some embodiments, the height adjustment device 3 may include a second limiting member 39. The second limiting member 39 may be located at one end of the lead screw 32. The second limiting member 39 may also be located at the end of the second threaded section 322 away from the first threaded section 321. The second limiting member 39 may abut against the end of the second sliding member 34 away from the first sliding member 33, and the second limiting member 39 can limit the sliding position of the first sliding member 33. Specifically, when the lead screw 32 rotates in the forward or reverse direction, the second sliding member 34 can slide between the second limiting member 39 and the rear end face of the connecting plate 31.

[0077] Please see Figure 5 As shown, in some embodiments, two first support rods 36 are provided. The upper ends of the two first support rods 36 can be rotatably connected to the opposite sides of the first sliding member 33. Specifically, the first sliding member 33 is provided with a first rotating shaft, which is rotatably mounted on the first sliding member 33, and its two ends extend through the opposite sides of the first sliding member 33. The first support rod 36 is provided with a first rotating hole, through which the first support rod 36 can rotatably engage with the first rotating shaft, thereby realizing the transmission connection between the first support rod 36 and the first sliding member 33.

[0078] Please see Figure 5 As shown, in some embodiments, two second support rods 37 are provided. The upper ends of the two second support rods 37 can be rotatably connected to the opposite sides of the second sliding member 34. Specifically, the second sliding member 34 is provided with a second rotating shaft, which is rotatably mounted on the second sliding member 34, with both ends of the second rotating shaft extending out from the opposite sides of the second sliding member 34. The second support rods 37 are provided with second rotating holes, through which the second support rods 37 can rotatably engage with the second rotating shaft, thereby realizing the transmission connection between the second support rods 37 and the second sliding member 34.

[0079] In some embodiments, the lower end of the first support rod 36 can be rotatably connected to the opposite sides of the base 35. The lower end of the second support rod 37 can be rotatably connected to the opposite sides of the base 35.

[0080] In some embodiments, two first support rods 36 and two second support rods 37 are symmetrically supported between the connecting plate 31 and the base 35, improving the stability of the support between the connecting plate 31 and the base 35. Furthermore, since the support points are distributed on opposite sides of the base 35, the force and load from the base 35 can be evenly distributed to the two sliders, avoiding stress concentration and enhancing the stability and load-bearing capacity of the structure.

[0081] Please see Figure 4 and Figure 5As shown, in some embodiments, the height adjustment device 3 may further include a guide rod 311, which may pass through the connecting plate 31 along its length, with the axial direction of the guide rod 311 parallel to the axial direction of the lead screw 32. The two ends of the guide rod 311 may be connected to the first limiting member 38 and the second limiting member 39, respectively. The first sliding member 33 and the second sliding member 34 are slidably disposed at opposite ends of the guide rod 311. Thus, the guide rod 311 can guide the first sliding member 33 and the second sliding member 34, thereby improving the stability of the first sliding member 33 and the second sliding member 34 during sliding.

[0082] In some embodiments, two guide rods 311 may be provided. The two guide rods 311 may be respectively located on both sides of the lead screw 32, and the first sliding member 33 is simultaneously connected and guided by both guide rods 311, allowing the two guide rods 311 to provide guidance for the first sliding member 33. Therefore, using two guide rods 311 can further improve the stability of the first sliding member 33 during sliding.

[0083] In some embodiments, the lead screw 32 may pass through the middle of the connecting plate 31. Two guide rods 311 may be respectively provided on opposite sides of the lead screw 32. Thus, the lead screw 32 and the two guide rods 311 can improve the balance on the connecting plate 31 and improve the stability of the connecting plate 31.

[0084] Please see Figure 8 As shown, in some embodiments, the base 35 may include a support plate 351. The support plate 351 may be disposed below the connecting plate 31. The lower end of the first support rod 36 is rotatably connected to one end of the support plate 351, and the lower end of the second support rod 37 is rotatably connected to the other end of the support plate 351. Thus, the first support rod 36 and the second support rod 37 can be used to raise or lower the height of the connecting plate 31 relative to the support plate 351.

[0085] Please see Figure 8 As shown, in some embodiments, the base 35 may include a pad 352. The pad 352 may be disposed below the support plate 351. The bottom surface of the pad 352 is used to support the base 35 on the ground. Thus, the pad 35 can be supported on the ground by means of the pad 352.

[0086] In some embodiments, an anti-slip pad 3521 may be provided at the bottom of the pad 352. The anti-slip pad 3521 may be a rubber pad, and anti-slip patterns 3522 may be formed on the anti-slip pad 3521. The anti-slip pad 3521 can directly contact the ground with all the anti-slip patterns 3522. The rubber material itself has a large coefficient of friction, which can significantly improve the friction between the refrigerator and the ground, effectively preventing the refrigerator body 1 from sliding or shifting. At the same time, the rubber is soft and elastic, which can buffer the direct hard contact between the refrigerator body 1 and the ground, providing good ground protection.

[0087] Please see Figure 8 As shown, in some embodiments, a first inclined surface 3511 and a second inclined surface 3512 are respectively provided on opposite sides of the bottom surface of the support plate 351. The first inclined surface 3511 can be inclined upward along the axial direction of the lead screw 32 in a direction away from the second inclined surface 3512. The second inclined surface 3512 is inclined upward along the other direction of the axial direction of the lead screw 32 in a direction away from the first inclined surface 3511. Specifically, in this embodiment, the first inclined surface 3511 can be inclined downward from the front end of the bottom surface of the support plate 351, and the second inclined surface 3512 can be inclined downward from the rear end of the bottom surface of the support plate 351. The first inclined surface 3511 and the second inclined surface 3512 can be connected at the middle of the bottom surface of the support plate 351.

[0088] Please see Figure 8 As shown, in some embodiments, the base 35 may further include a first slider 353, which is slidably disposed on the top surface of the pad 352. The first slider 353 is disposed between the top surface of the pad 352 and the first inclined surface 3511. A second slider 354 is slidably disposed on the top surface of the pad 352. The second slider 354 is disposed between the top surface of the pad 352 and the second inclined surface 3512. Thus, the first slider 353 and the second slider 354 can be used to support the support plate 351 using the pad 352. By using the first slider 353 and the second slider 354 respectively disposed at the front and rear ends of the pad 352, the stability of the support between the support plate 351 and the pad 352 is improved.

[0089] In some embodiments, a first slider 353 is slidably disposed between the top surface of the pad 352 and the first inclined surface 3511, thereby adjusting the distance between the first inclined surface 3511 and the front end of the pad 352 by sliding the first slider 353. Specifically, when the first slider 353 moves toward the bottom end of the first inclined surface 3511, the height of the first inclined surface 3511 relative to the pad 352 increases; when the first slider 353 moves away from the bottom end of the first inclined surface 3511, the height of the first inclined surface 3511 relative to the pad 352 decreases. Thus, the first slider 353 can be used to level the support plate 351 and the pad 352, thereby preventing the housing 1 from shaking due to ground inclination.

[0090] In some embodiments, a second slider 354 is slidably disposed between the top surface of the pad 352 and the second inclined surface 3512, thereby adjusting the distance between the second inclined surface 3512 and the rear end of the pad 352 by sliding the second slider 354. Specifically, when the second slider 354 moves toward the bottom end of the second inclined surface 3512, the height of the second inclined surface 3512 relative to the pad 352 increases; when the second slider 354 moves away from the bottom end of the second inclined surface 3512, the height of the second inclined surface 3512 relative to the pad 352 decreases. Thus, the second slider 354 can be used to level the support plate 351 and the pad 352, thereby preventing the housing 1 from shaking due to ground inclination.

[0091] Please see Figure 8 As shown, in some embodiments, the base 35 also includes a first drive shaft 355. The axial direction of the first drive shaft 355 may be parallel to the axial direction of the lead screw 32. The first drive shaft 355 may be provided with a third threaded section 3552. The first slider 353 is threadedly connected to the third threaded section 3552. Thus, when the first drive shaft 355 rotates in the forward direction, it can drive the first slider 353 to move towards the bottom end of the first inclined surface 3511, thereby increasing the height of the first inclined surface 3511 relative to the pad 352; when the first drive shaft 355 rotates in the reverse direction, it can drive the first slider 353 to move away from the bottom end of the first inclined surface 3511, thereby decreasing the height of the first inclined surface 3511 relative to the pad 352. Thus, by utilizing the cooperation between the third threaded section 3552 on the first drive shaft 355 and the first slider 353, the movement direction of the first inclined surface 3511 can be quickly controlled, thereby making leveling between the support plate 351 and the pad 352 simpler.

[0092] In some embodiments, the end of the first drive shaft 355 may be provided with a first adjustment groove 3551. The user can rotate the first drive shaft 355 by using a wrench that is connected to the first adjustment groove 3551, thereby achieving leveling between the first inclined surface 3511 and the pad 352.

[0093] Please see Figure 8As shown, in some embodiments, the base 35 further includes a second drive shaft 356. The axial direction of the second drive shaft 356 may be parallel to the axial direction of the lead screw 32. The second drive shaft 356 may be provided with a fourth threaded section 3562. The second slider 354 is threadedly connected to the fourth threaded section 3562. Thus, when the second drive shaft 356 rotates in the forward direction, it can drive the second slider 354 to move towards the bottom end of the second inclined surface 3512, thereby increasing the height of the second inclined surface 3512 relative to the pad 352; when the second drive shaft 356 rotates in the reverse direction, it can drive the second slider 354 to move away from the bottom end of the second inclined surface 3512, thereby decreasing the height of the second inclined surface 3512 relative to the pad 352. Thus, by utilizing the cooperation between the fourth threaded section 3562 on the second drive shaft 356 and the second slider 354, the movement direction of the second inclined surface 3512 can be quickly controlled, thereby making leveling between the support plate 351 and the pad 352 simpler.

[0094] In some embodiments, the end of the second drive shaft 356 may be provided with a second adjustment groove 3561. The user can rotate the second drive shaft 356 by using a wrench that is connected to the second adjustment groove 3561, thereby achieving leveling between the second inclined surface 3512 and the pad 352.

[0095] Please see Figure 8 As shown, in some embodiments, a first guide section 3553 is provided at the end of the first drive shaft 355 away from the third threaded section 3552. The first guide section 3553 can pass through the second slider 354, and the first guide section 3553 can rotate relative to the second slider 354. When the second drive shaft 356 rotates, the second slider 354 can slide along the second drive shaft 356 through the fourth threaded section 3562, and the second slider 354 can slide along the first guide section 3553.

[0096] In some embodiments, a second guide section 3563 is provided at the end of the second drive shaft 356 away from the fourth threaded section 3562. The second guide section 3563 can pass through the first slider 353 and can rotate relative to the first slider 353. When the first drive shaft 355 rotates, the first slider 353 can slide along the first drive shaft 355 through the third threaded section 3552, and the first slider 353 can slide along the second guide section 3563.

[0097] Please see Figure 9As shown, in some embodiments, a first groove 3513 is recessed on the first inclined surface 3511. The first groove 3513 extends axially along the first drive shaft 355, which is rotatably disposed within the first groove 3513. The top of the first slider 353 slidably extends into the first groove 3513 and is threadedly connected to a third threaded section 3552 on the first drive shaft 355. Thus, when the first drive shaft 355 rotates, the first slider 353 can slide along the extending direction of the first groove 3513 towards or away from the bottom end of the first inclined surface 3511.

[0098] Please see Figure 9 As shown, in some embodiments, a second groove 3514 is recessed on the second inclined surface 3512. The second groove 3514 extends axially along the second drive shaft 356, which is rotatably disposed within the second groove 3514. The top of the second slider 354 slidably extends into the second groove 3514 and is threadedly connected to the fourth threaded section 3562 on the second drive shaft 356. Thus, when the second drive shaft 356 rotates, the second slider 354 can slide along the extending direction of the second groove 3514 towards or away from the bottom end of the second inclined surface 3512.

[0099] Please see Figure 8 and Figure 9 As shown, in some embodiments, a limiting post 3523 can extend upward from the top surface of the pad 352. A through hole 3515 is provided on the support plate 351, and the upper end of the limiting post 3523 passes through the through hole 3515 and is positioned above the top of the support plate 351. An adjusting nut 3524 is provided at the top of the limiting post 3523, and the adjusting nut 3524 is threadedly connected to the limiting post 3523. A buffer spring 3525 is provided on the limiting post 3523, with the upper end of the buffer spring 3525 abutting against the adjusting nut 3524 and the lower end of the buffer spring 3525 abutting against the top surface of the support plate 351. Therefore, when the first slider 353 or the second slider 354 slides within the inclined plane to adjust the relative position between the support plate 351 and the pad 352, the buffer spring 3525 can buffer and reset the support plate 351. Meanwhile, by using the two ends of the buffer spring 3525 to limit the top surface of the adjusting nut 3524 and the support plate 351, the buffer spring 3525 can also play an elastic pressing role on the support plate 351.

[0100] In some embodiments, the top surface of the support plate 351 may be provided with a first baffle 3526, through which the lower end of the buffer spring 3525 abuts against the top surface of the support plate 351. The bottom surface of the adjusting nut 3524 is provided with a second baffle 3527, through which the upper end of the buffer spring 3525 abuts against the adjusting nut 3524. Thus, the first baffle 3526 and the second baffle 3527 can improve the stability of the buffer spring 3525 when it abuts against the top surface of the support plate 351 and the adjusting nut 3524.

[0101] In some embodiments, the through hole 3515 may include a first through hole 3515 and a second through hole 3515. The first through hole 3515 may be formed on the first inclined surface 3511. The second through hole 3515 may be formed on the second inclined surface 3512. Two sets of limiting posts 3523 may be provided, wherein the two limiting posts 3523 may respectively pass through the first through hole 3515 and the second through hole 3515, and the number of limiting posts 3523 may correspond one-to-one with the number of the first through hole 3515 and the second through hole 3515.

[0102] In some embodiments, multiple sets of limiting posts 3523 may be provided, and through holes 3515 may include multiple first through holes 3515 and multiple second through holes 3515. At least one set of limiting posts 3523 passes through the first through holes 3515, and at least one set of limiting posts 3523 passes through the second through holes 3515. This provides buffering between the first inclined surface 3511 and the top surface of the pad 352 through the limiting posts 3523 passing through the first through holes 3515, and buffering between the second inclined surface 3512 and the top surface of the pad 352 through the limiting posts 3523 passing through the second through holes 3515.

[0103] Please see Figure 10 and Figure 11 As shown, in some embodiments, an arc-shaped portion 3516 may be protruding from the bottom surface of the support plate 351. The arc-shaped portion 3516 may be located between the bottom end of the first inclined surface 3511 and the bottom end of the second inclined surface 3512. An arc-shaped groove 3528 is recessed on the top surface of the pad 352, and the lower end surface of the arc-shaped portion 3516 is an arc-shaped surface that can abut against the bottom wall of the arc-shaped groove 3528. Thus, the arc-shaped portion 3516 and the arc-shaped groove 3528 can achieve support between the support plate 351 and the pad 352, thereby improving the stability of the support between the support plate 351 and the pad 352.

[0104] In some embodiments, the arcuate surface is adapted to the bottom wall of the arcuate groove 3528, and the arcuate surface and the bottom wall of the arcuate groove 3528 abut against each other, thereby increasing the contact area between the support plate 351 and the pad 352, and further improving the stability of the support between the support plate 351 and the pad 352.

[0105] In some embodiments, the arc-shaped portion 3516 is disposed between the first inclined surface 3511 and the second inclined surface 3512, that is, the contact point between the arc-shaped portion 3516 and the arc-shaped groove 3528 is disposed between the first slider 353 and the second slider 354. Thus, the first slider 353 and the second slider 354 are used to support the support plate 351 at both ends of the pad 352, and the arc-shaped portion 3516 is used to support the support plate 351 at the middle of the pad 352, thereby making the support between the support plate 351 and the pad 352 more stable.

[0106] In some embodiments, a positioning portion 3517 is provided on the bottom surface of the arc-shaped portion 3516. A positioning groove 3529 is recessed on the bottom wall of the arc-shaped groove 3528. When the arc-shaped portion 3516 abuts against the bottom wall of the arc-shaped groove 3528, the positioning portion 3517 extends into the positioning groove 3529. Thus, the positioning portion 3517 and the positioning groove 3529 can be used to position the support position between the support plate 351 and the pad 352.

[0107] In some embodiments, the refrigeration equipment may include a level. The level may be located on the top surface of the housing 1. The level can determine whether the housing 1 is installed level by observing whether the internal bubble is at the center position, thereby assisting in determining whether the housing 1 is placed vertically and stably, avoiding errors caused by visual observation.

[0108] It should be noted that in some other embodiments, the level may be mounted on the door 11 or the support plate 352.

[0109] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
