Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0040] It should be noted that, where there is no conflict, different features in the embodiments of this utility model can be combined with each other.
[0041] The inventor's investigation revealed that during the assembly of the sliding door, the door's own weight caused it to tilt downwards, resulting in a larger gap between the door and the frame. This larger gap was located at the top of the door, creating a significant difference in clearance. This excessive gap leads to the door not closing properly, causing cold air leakage, increased energy consumption, and making the upper part of the door prone to condensation, potentially even frosting. Furthermore, the top of the door is where the handle is located, significantly impacting the user experience.
[0042] In view of this, the present invention provides a refrigeration device 10, please refer to [link / reference]. Figure 1 A refrigeration device 10 is provided, including a housing 100 having an opening 101, a door 200, and at least one adjustment component 300 disposed on the door 200.
[0043] In the refrigeration equipment 10, the cabinet 100 includes a shell and an inner liner. The shell is located as the outermost layer of the refrigeration equipment 10, used to enclose and support the entire refrigeration equipment 10; the interior of the shell includes the inner liner, which is a plastic cavity for storing food, forming storage spaces such as refrigerator compartments and freezers; a heat insulation layer is also formed between the shell and the inner liner, as well as inside the door 200, through foaming to improve the cooling effect of the refrigeration equipment 10. After the foaming process and during use, the door 200 of the refrigeration equipment 10 may tilt downwards due to its own weight, resulting in a decrease in the seal between the door 200 and the cabinet 100.
[0044] The door 200 is slidably connected to the box 100; the door 200 is used to open or close the opening 101.
[0045] In this embodiment, the door 200 may include a drawer door, which can be connected to the box 100 via a connecting component 400 such as a guide rail, thereby achieving a sliding connection between the door 200 and the box 100.
[0046] Please see Figure 2 , Figure 2 This is a structural diagram of the lower part of the door body 200 and the through hole 220. The door body 200 has at least one through hole 220 that penetrates horizontally through the side of the door body 200 near the bottom wall of the housing 100; see [link to diagram]. Figure 3 The orthographic projection of the bottom wall of the housing 100 onto the side of the door 200 near the housing 100 covers the orthographic projection of the through hole 220 onto the side of the door 200 near the housing 100; the inner diameter of the through hole 220 is a first diameter. The through hole 220 is used to fix the adjustment assembly 300.
[0047] Please see Figure 4 The adjusting assembly 300 includes an adjusting bolt 320, an adjusting nut 310, and an elastic fastener 330. (See also...) Figure 5 and Figure 6 The adjusting nut 310 is embedded in the through hole 220 and fixedly connected to the door body 200. The outer diameter of the adjusting nut 310 is the second diameter, and the first diameter is smaller than the second diameter. Please refer to [link / reference]. Figure 7The adjusting bolt 320 includes a bolt head 321 and a bolt shank 322. The external thread on the surface of the bolt shank 322 matches the internal thread of the adjusting nut 310. The adjusting bolt 320 is at least partially screwed into the adjusting nut 310 from the side of the door 200 near the box 100, so that the bolt head 321 and the side of the door 200 near the box 100 have an adjustable gap. An elastic fastener 330 is provided between the bolt head 321 and the door 200. The elastic fastener 330 is used to support the adjusting bolt 320 to prevent the adjusting bolt 320 from displacing relative to the adjusting nut 310 when there is no external force.
[0048] In this embodiment, the first diameter is smaller than the second diameter in order to achieve an interference fit between the adjusting nut 310 and the through hole 220. The interference fit ensures that the adjusting nut 310 can be fixed in the through hole 220 of the door body 200, preventing loosening or falling off during use. The radial pressure generated can enhance the sealing of the connection part. This structure can also disperse the vibration load generated when the door body 200 is opened and closed, and improve the overall stability of the adjusting assembly 300.
[0049] In practice, an adjusting nut 310 with an outer diameter slightly larger than the inner diameter of the through hole 220 is pressed into the through hole 220, forming a tight mechanical fit between them. This fit method does not require additional fasteners or adhesives, simplifying the assembly process while ensuring a secure connection between the adjusting nut 310 and the through hole 220. Furthermore, this design facilitates later maintenance; if the adjusting component 300 needs to be replaced, simply press the original adjusting nut 310 out of the through hole 220 without damaging the structure of the door body 200.
[0050] In this embodiment, please refer to Figure 5In the direction perpendicular to the side of the door 200 near the housing 100, the distance gap between the bolt head 321 and the side of the door 200 near the housing 100 can be controlled by screwing the adjusting bolt 320 into different positions of the adjusting nut 310. Specifically, the adjusting bolt 320 is supported by the lower beam of the housing 100, which can prevent the door 200 from tilting further in the vertical direction, thereby ensuring the uniformity of the vertical gap of the door 200. In addition, this utility model also provides an elastic fixing member 330 to support the adjusting bolt 320, so as to prevent the adjusting bolt 320 from shifting relative to the adjusting nut 310 when there is no external force, and also to play a buffering role during the opening and closing of the door 200. This adjustable gap design allows the assembler to flexibly adjust the distance between the door 200 and the housing 100 according to the actual situation, thereby solving the problem of cold air leakage and increased energy consumption caused by the door 200 tilting due to gravity after assembly, resulting in a smaller gap between the lower part of the door 200 and the housing 100.
[0051] In one possible implementation, please refer to Figure 4 The elastic fastener 330 includes a limiting washer 331 and an elastic element 332. The limiting washer 331 includes an internal thread that matches the external thread on the surface of the bolt shank 322. The limiting washer 331 is screwed onto the bolt shank 322 and abuts against the door body 200.
[0052] An elastic element 332 is provided between the limiting washer 331 and the bolt head 321. The elastic element 332 includes an axial compression elastic device to prevent the bolt head 321 from axially displacing relative to the limiting washer 331 when there is no external force.
[0053] In this embodiment, the synergistic effect of the limiting washer 331 and the elastic element 332 solves the problem of loosening after long-term use of the refrigeration equipment 10 following the movable connection of the adjusting bolt 320 and the adjusting nut 310. The limiting washer 331 provides a stable positioning reference through threaded engagement, while simultaneously forming a friction lock by adhering to the surface of the door 200; the elastic element 332 continuously applies axial pressure to the bolt head 321 and the limiting washer 331, ensuring that the entire adjusting assembly 300 maintains a stable connection even under vibration or temperature changes. This ensures that the gap of the adjusted door 200 remains constant over a long period, avoiding the need for frequent manual adjustments by the user.
[0054] In one possible implementation, please refer to Figure 8 The elastic element 332 includes a helical compression spring, which is coaxially sleeved on the bolt shank 322.
[0055] The first end face of the helical compression spring abuts against the limiting washer 331, and the second end face of the helical compression spring abuts against the bolt head 321; in the assembled state of the adjusting assembly 300, the helical compression spring undergoes axial compression deformation.
[0056] In this embodiment, the elastic properties of the helical compression spring can absorb impact energy when the door 200 is closed, thereby protecting the contact surface between the adjustment assembly 300 and the housing 100; the elastic force of the helical compression spring provides uniform axial pressure to the bolt head 321 and the limiting washer 331, making the adjustment process more stable and easier for the user to control, and also ensuring that the entire adjustment assembly 300 can maintain a stable connection state under vibration or temperature change conditions after adjustment.
[0057] It should be noted that, apart from the helical compression spring, any other elastic component that can provide uniform axial pressure to the bolt head 321 and the limiting washer 331 can be used as the elastic element 332 in this embodiment, and no specific limitation is made here.
[0058] In one possible implementation, please refer to Figure 7 The bolt shank 322 has an axially oriented adjustment scale 323 on its surface, which indicates the amount of rotation adjustment of the adjusting bolt 320 relative to the adjusting nut 310.
[0059] Specifically, the adjustment scale 323 may have a zero mark, which corresponds to the design position of the standard assembly gap between the door 200 and the housing 100. This position may be marked with a red laser. Other adjustment scales 323 may be set along the bolt axis on one side of the zero mark. All scales and their corresponding values may be permanently marked by laser etching.
[0060] In this way, by observing the relative position of the end face of the adjusting nut 310 and the adjusting scale 323, the assembler can more accurately carry out fine-tuning operations on the adjusting component 300.
[0061] In one possible implementation, the adjustment scale 323 includes a plurality of evenly spaced graduations, with an axial spacing of 0.5 mm between adjacent graduations.
[0062] In this embodiment, by setting multiple 0.5mm intervals between scale lines, the difficulty of operation for operators when adjusting the adjustment component 300 can be reduced, thereby allowing for more precise adjustment of the tilt of the door 200.
[0063] It should be noted that, in this embodiment, the spacing between adjacent scribe lines can be adjusted adaptively according to the different sizes of the refrigeration device 10, and no specific limitation is made here.
[0064] In one possible implementation, the door 200 has a first through hole and a second through hole on the side of the bottom wall near the box 100, which penetrate the side of the door 200 near the box 100 in the horizontal direction, wherein the first through hole and the second through hole are symmetrically arranged on the door 200.
[0065] The refrigeration equipment 10 includes a first regulating component and a second regulating component.
[0066] The first adjusting assembly includes a first adjusting bolt, a first adjusting nut, and a first elastic fastener; the first adjusting nut is disposed in the first through hole, the first adjusting bolt is at least partially screwed into the first adjusting nut, and the first elastic fastener is used to fix the distance between the first bolt head of the first adjusting bolt and the first adjusting nut.
[0067] The second adjusting assembly includes a second adjusting bolt, a second adjusting nut, and a second elastic fastener; the second adjusting nut is disposed in the second through hole, the second adjusting bolt is at least partially screwed into the second adjusting nut, and the second elastic fastener is used to fix the distance between the second bolt head of the second adjusting bolt and the second adjusting nut.
[0068] In this embodiment, the symmetrical layout of the first and second adjustment components allows for independent gravity compensation adjustment of the left and right sides of the door. Specifically, when the left side of the door sinks, tightening the first adjustment bolt on the left side raises the left side; when the right side sinks, tightening the second adjustment bolt on the right side raises the right side; the adjustment operations on both sides do not interfere with each other. This effectively eliminates the asymmetrical gap difference caused by unilateral tilting of the door.
[0069] In one possible implementation, please refer to Figure 2 The door 200 includes a decorative strip 210 located on one side near the bottom wall of the box 100, and the through hole 220 is provided on the decorative strip 210.
[0070] In this embodiment, the decorative strip 210 and the main body of the door 200 can be connected by a detachable snap-on connection / adhesive fixation or other connection methods. When the through hole 220 is worn due to long-term use, the decorative strip 210 is damaged, or the opening position needs to be adjusted, the decorative strip 210 can be replaced separately by simply disconnecting the connection between the decorative strip 210 and the main body of the door 200, without disassembling the door 200.
[0071] In one possible implementation, the surface of the bolt head 321 is provided with a protective layer, wherein the material of the protective layer includes a flexible material.
[0072] For example, the protective layer material can be soft polyvinyl chloride modified with wear-resistant agents. In this way, when the door 200 is closed, at the moment the bolt head 321 hits the lower beam of the housing 100, the soft polyvinyl chloride layer absorbs most of the impact energy through elastic deformation, thereby avoiding damage to the paint surface of the refrigeration equipment 10 caused by direct metal-to-metal collision between the bolt head 321 and the housing 100.
[0073] It should be noted that, since the protective layer needs to be in long-term contact and friction with the door body 200, the material of the protective layer should be treated with wear resistance or a wear-resistant material should be selected. This can extend the service life of the adjustment component 300 and the protective layer located on it.
[0074] In one possible implementation, the refrigeration device 10 further includes a sealing ring located on the side of the door 200 near the housing 100, the sealing ring being at a first distance at a height perpendicular to the side of the door 200 near the housing 100; the axial height of the adjusting bolt 320 being a second distance; wherein the first distance is greater than or equal to the second distance.
[0075] In this embodiment, in order to avoid affecting the sealing between the door 200 and the cabinet 100 of the refrigeration equipment 10 due to excessive adjustment of the adjustment component 300, the height of the sealing ring on the side of the door 200 near the cabinet 100 is greater than or equal to the axial height of the adjustment bolt 320.
[0076] In one possible implementation, please refer to Figure 9 The refrigeration equipment 10 also includes a connecting component 400, which includes a guide rail, a sliding part and a support base fixedly connected to the sliding part, all disposed within the housing 100. The support base is also connected to the side of the door 200 near the housing 100.
[0077] The sliding part is slidably connected to the guide rail, and the sliding part is used to drive the door body 200 to slide along the guide rail in a direction perpendicular to the side of the door body 200 close to the box body 100.
[0078] In this embodiment, the door 200 may include a drawer door; the sliding part in the connecting assembly 400 forms a sliding fit with the guide rail, which can drive the drawer door to slide smoothly along the guide rail in a direction perpendicular to the side of the door 200 near the box 100, thereby realizing the opening and closing action of the door 200. Since the adjusting assembly 300 can adjust the deviation caused by the downward tilt of the door 200 due to its own weight after the door 200 is assembled with the box 100, the sealing performance of the door 200 is ensured.
[0079] In summary, this utility model provides a refrigeration device 10, including a housing 100, a door 200, and an adjustment assembly 300; the door 200 has at least one through hole 220 on the side of the bottom wall near the housing 100, penetrating horizontally through the side of the door 200 near the housing 100; the adjustment assembly 300 includes an adjustment bolt 320, an adjustment nut 310, and an elastic fastener 330, the adjustment nut 310 is embedded in the through hole 220 and fixedly connected to the door 200; the adjustment bolt 320 includes a bolt head 321 and a bolt shank 322, the adjustment bolt 320 is at least partially screwed into the adjustment nut 310 from the side of the door 200 near the housing 100; the bolt head 321 and the door 200 have an elastic fastener 330 between them. In the direction perpendicular to the side of the door 200 near the housing 100, by screwing the adjusting bolt 320 into different positions of the adjusting nut 310, an adjustable gap is created between the bolt head 321 and the side of the door 200 near the housing 100. The adjusting bolt 320 is supported by the elastic fastener 330 to prevent displacement. The gap is used to adjust the consistency of the distance between the door 200 and the housing 100, thereby adjusting the deviation caused by the downward tilt of the door 200 due to its own weight after assembly with the housing 100.
