[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-15A refrigerator 100 according to an embodiment of the present invention is described.

[0037] like Figure 1-Figure 3 As shown, the refrigerator 100 according to an embodiment of the present invention includes a box body (not shown in the figure), a door body (not shown in the figure), at least one drawer 2 and a guide rail bracket 3.

[0038] Specifically, if Figure 1-Figure 3 As shown, the box body includes a refrigerated liner 11 and a back plate 12. The thickness direction of the refrigerated liner 11 (for example, Figure 3 An opening 111 is formed on one side (in the left-right direction in the horizontal direction), and a back panel 12 is provided on the other side of the refrigerated inner container 11 in the thickness direction. A door is provided at opening 111 for opening and closing. The door and refrigerated inner container 11 together define a storage chamber 112. The drawer 2 is provided within the storage chamber 112, and a portion of the guide rail bracket 3 is provided within the storage chamber 112. The guide rail bracket 3 is slidably connected to the drawer 2.

[0039] For example, in Figure 1-Figure 3 In the example shown, the back panel 12 and the door are respectively provided on opposite sides of the refrigerated liner 11 in the thickness direction, and the refrigerated liner 11 can be located above the back panel 12. The guide rail bracket 3 is generally an irregular plate-shaped structure, and a portion of the guide rail bracket 3 extends into the accommodating cavity 112, and is used for sliding connection with the drawer 2 to adjust the height of the drawer 2.

[0040] In addition, the refrigerator 100 further includes an adjustment mechanism 4, which is provided in the height direction of the refrigeration liner 11 (for example, Figure 3 The adjustment mechanism 4 includes at least one transmission gear 41, and the guide rail bracket 3 has at least one rack portion 31. The rack portion 31 is located outside the refrigerated inner container 11 and extends along the height direction of the refrigerated inner container 11. The rack portion 31 meshes with the transmission gear 41. The transmission gear 41 rotates to drive the guide rail bracket 3 and the drawer 2 to move along the height direction of the refrigerated inner container 11.

[0041] For example, in Figure 1-Figure 3 In the example, two transmission gears 41 and two rack portions 31 are provided, and the two transmission gears 41 are respectively provided on both sides of the thickness direction of the refrigerated inner container 11. Specifically, the transmission gear 41 can be fixed below the refrigerated inner container 11. When the transmission gear 41 rotates, it drives the rack portion 31 to move linearly along the height direction of the refrigerated inner container 11. Since the guide rail bracket 3 is connected to the drawer 2, it can drive the guide rail bracket 3 and the drawer 2 to move along the height direction of the refrigerated inner container 11. In this way, the position of the drawer 2 in the height direction of the refrigerated inner container 11 is adjusted so that the drawer 2 can always remain parallel to the refrigerated inner container 11, avoiding the problem of the drawer 2 tilting, thereby improving the overall aesthetics of the refrigerator 100.

[0042] Moreover, the setting of the adjustment mechanism 4 can avoid the time-consuming and labor-intensive problem of repeatedly adjusting the foaming mold, while reducing production costs. Setting the adjustment mechanism 4 in the refrigerated inner tank 11 can better utilize the space of the accommodating cavity 112, thereby improving space utilization.

[0043] According to the refrigerator 100 of the present invention, a guide rail bracket 3 is provided in the refrigerated inner tank 11, and an adjustment mechanism 4 is provided below the refrigerated inner tank 22, and the rack portion 31 of the guide rail bracket 3 is engaged with the transmission gear 41 of the adjustment mechanism 4. Thus, the position of the drawer 2 in the height direction of the refrigerated inner tank 11 can be adjusted by the adjustment mechanism 4, and during the adjustment process, the drawer 2 can always remain parallel to the refrigerated inner tank 11, avoiding the problem of tilting of the drawer 2, thereby improving the overall aesthetics of the refrigerator 100, and avoiding repeated adjustment of the foaming mold, saving time and effort and having low production costs.

[0044] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the adjustment mechanism 4 further includes a rotating shaft 42 and a rotating wheel 43. The rotating shaft 42 extends along the thickness direction of the refrigerated liner 11, and one end of the rotating shaft 42 is pivotally connected to the back plate 12. The transmission gear 41 is fixed to the rotating shaft 42. The rotating wheel 43 is located on the side of the back plate 12 away from the refrigerated liner 11 and is fixedly connected to one end of the rotating shaft 42.

[0045] With such an arrangement, the rotation of the transmission gear 41 can be precisely controlled by rotating the wheel 43, thereby achieving height adjustment of the drawer 2. The wheel is arranged on the outside of the back panel 12, which makes it convenient for the user to rotate the rotating shaft 42 through the wheel 43 outside the refrigerator 100, making the operation easier.

[0046] In addition, the pivotal connection between the rotating shaft 42 and the back plate 12 and the fixed connection between the transmission gear 41 and the rotating shaft 42 ensure the stability and reliability of the adjustment mechanism 4 and ensure that the adjustment mechanism 4 can operate smoothly during the adjustment process.

[0047] Specifically, if Figure 4 and Figure 5 As shown, the outer circumference of the rotating wheel 43 has an anti-slip portion 431, and a tooth-shaped structure is formed on the anti-slip portion 431 to increase the friction between the rotating wheel 43 and the user's hand, so that the user can more easily rotate the rotating wheel 43. Along the axial direction of the rotating wheel 43, a structural hole 432 is formed on the rotating wheel 43. The structural hole 432 can be a polygonal hole (such as Figure 5 Similarly, the cross-sectional shape of the rotating shaft 42 can be hexagonal to increase the torque between the rotating wheel 43 and the rotating shaft 42 and prevent the rotating wheel 43 and the rotating shaft 42 from moving relative to each other during rotation.

[0048] In addition, a plurality of inner ring reinforcement ribs 433 are formed on the runner 43 to enhance the connection strength of the runner 43 and ensure the working reliability of the runner 43. In the description of the present utility model, the meaning of "multiple" is two or more. For example, in Figure 5 In the example, the number of the inner ring reinforcement ribs 433 is 8, and the 8 inner ring reinforcement ribs 433 are arranged at intervals around the axial direction of the rotating shaft 42.

[0049] Further, if Figure 6-Figure 8 As shown, the refrigerator 100 further includes a mounting box 5 , which is disposed on one side in the height direction of the refrigeration liner 11 . At least one protrusion 51 is disposed in the mounting box 5 , and the mounting box 5 and the refrigeration liner 11 jointly define a mounting cavity 523 .

[0050] For example, in Figure 9 In the example shown in FIG, two protrusions 51 are provided in the mounting box 5, and the two protrusions 51 are spaced apart between the two transmission gears 41. The transmission gears 41 and a portion of the rotating shaft 42 are located in the mounting cavity 523. A mating hole 511 is formed on the protrusion 51, and the rotating shaft 42 is inserted into the mating hole 511, with a clearance fit between the rotating shaft 42 and the mating hole 511.

[0051] The installation box 5 centrally houses components such as the transmission gear 41 and the rotating shaft 42 within the installation cavity 523, thereby protecting these components from external influences. This also makes the refrigerator 100 more neat and orderly, and facilitates maintenance and inspection of the adjustment mechanism 4, thereby improving the maintainability of the refrigerator 100. Furthermore, the clearance between the rotating shaft 42 and the mating hole 511 on the protrusion 51 ensures the rotational stability of the rotating shaft 42, making the adjustment process smoother.

[0052] In a specific implementation, a relief hole 521 (such as Figure 12 As shown), ensure that the rack portion 31 does not interfere with the mounting box 5 when moving.

[0053] Alternatively, as Figure 7 As shown, a through hole 512 is provided on the protrusion 51 to reduce the overall weight of the protrusion 51, save material costs, and facilitate the lightweight design of the refrigerator 100.

[0054] In some optional embodiments, such as Figure 10 and Figure 11 As shown, a sleeve 6 is sleeved on the rotating shaft 42, and the sleeve 6 is located between the mounting box 5 and the back plate 12, and one end of the sleeve 6 is connected to the mounting box 5. A positioning hole 522 is formed in one of the sleeve 6 and the mounting box 5, and a positioning post 61 is provided on the other of the sleeve 6 and the mounting box 5, and the positioning post 61 cooperates with the positioning hole 522.

[0055] For example, in Figure 10 and Figure 11 In the example shown in FIG, a positioning post 61 is provided on the sleeve 6, and a positioning hole 522 is formed on the mounting box 5. The cooperation between the positioning post 61 and the positioning hole 522 ensures that the rotation shaft 42 is accurately positioned between the mounting box 5 and the back plate 12, thereby ensuring the accuracy of the adjustment mechanism 4, facilitating the assembly of the mounting box 5, the rotation shaft 42 and other components, and improving production efficiency and assembly quality.

[0056] Of course, in other embodiments, a positioning hole is formed on the sleeve 6, and a positioning column is provided on the installation box 5 (not shown).

[0057] The provision of the sleeve 6 increases the stability of the connection between the rotating shaft 42 and the mounting box 5, making the entire adjustment mechanism 4 more secure and reliable, and effectively preventing the rotating shaft 42 from loosening during use, thereby ensuring the normal use and long-term stability of the refrigerator 100. In addition, the sleeve 6 can seal the rotating shaft 42, preventing the foam from affecting the rotating shaft 42 during the foaming process of the refrigerator body.

[0058] According to some embodiments of the present invention, Figure 13 and Figure 14 As shown, an external thread 421 is formed at one end of the rotating shaft 42. The adjustment mechanism 4 further includes a locking member 44, which is disposed between the back plate 12 and the rotating wheel 43. The locking member 44 is formed with an internal thread (not shown) that cooperates with the external thread 421. The locking member 44 can be a locking nut, etc., but is not limited thereto.

[0059] When the height of the guide rail bracket 3 needs to be adjusted, the user rotates the wheel 43, and the wheel 43 drives the rotating shaft 42. The transmission gear 41 on the rotating shaft 42 engages with the rack portion 31 on the guide rail bracket 3, driving the guide rail bracket 3 to move up and down, thereby driving the drawer 2 to move up and down; when the guide rail bracket 3 reaches the appropriate height, the rotation of the wheel 43 is stopped, and the locking piece 44 is rotated until the locking piece 44 abuts against the back panel 12 to lock the rotating shaft 42. At this time, the entire adjustment mechanism 4 is in a stationary state, and the adjustment work is completed.

[0060] Therefore, through the cooperation between the external thread 421 and the internal thread, the rotating shaft 42 can be locked to ensure the stability of the position of the rotating shaft 42 after the adjustment work is completed, and prevent the rotating shaft 42 from loosening during daily use of the refrigerator 100, which may cause the position of the drawer 2 to change. The adjustment and locking operations are simple and convenient, thereby improving the user experience.

[0061] Optionally, along the axial direction of the rotating shaft 42 , the length of the external thread 421 is greater than the length of the internal thread, so that the position of the locking member 44 on the rotating shaft 42 can be flexibly adjusted.

[0062] According to some embodiments of the present invention, Figure 6 and Figure 15 As shown, the mounting box 5 includes a body 52 and multiple lugs 53. The body 52 is provided with a protrusion 51. The lugs 53 are located on both sides of the body 52 in the thickness direction of the refrigerated liner 11. Fasteners 7 pass through the refrigerated liner 11 and connect to corresponding lugs 53. Multiple reinforcing ribs 54 are formed on the inner sidewall of the body 52. ​​These ribs 54 are spaced apart along the thickness direction of the refrigerated liner 11, and each rib 54 extends along the height direction of the refrigerated liner 11. The fasteners 7 may be screws, etc., but are not limited thereto.

[0063] For example, in Figure 8 In the example shown, four lugs 53 are provided, one at each corner of the box body 52. ​​Reinforcing ribs 54 are provided, spaced apart on the inner sidewall of the box body. During installation, one end of the fastener 7 passes through the refrigerated liner 11 and connects to the lugs 53, ensuring a secure connection between the installation box 5 and the refrigerated liner 11 and preventing the installation box 5 from falling off. The provision of multiple reinforcing ribs 54 on the box body 52 enhances the structural strength of the installation box 5, allowing it to better withstand external forces and improving its overall stability and reliability.

[0064] Furthermore, there are multiple rack parts 31 and multiple transmission gears 41, and the multiple rack parts 31 correspond to the multiple transmission gears 41 one by one. The multiple rack parts 31 are spaced apart along the thickness direction of the refrigerated inner container 11. For example, Figure 3 In the example, there are two racks 31 and two transmission gears 41. By aligning multiple racks 31 with multiple transmission gears 41, the drawer 2 is subjected to a more balanced force during movement, improving the smoothness of adjustment. Multiple racks 31 are spaced apart along the thickness of the refrigerated liner 11, enabling synchronous adjustment of different parts of the drawer 2. This ensures more stable and reliable movement of the drawer 2 in the height direction and improves the reliability of the adjustment mechanism 4. Furthermore, the adjustment mechanism 4 can better adapt to drawers 2 of different sizes and quantities, meeting diverse usage requirements.

[0065] According to some embodiments of the present invention, multiple drawers 2 are provided, each located on either side of the guide rail bracket 3 in the width direction of the refrigerator liner 11. Distributing the multiple drawers 2 on both sides of the guide rail bracket 3 effectively utilizes the width of the refrigerator liner 11, increasing the storage capacity of the refrigerator 100. Furthermore, different items can be placed in drawers 2 on different sides, facilitating classification and management, and ensuring more organized storage. Furthermore, this design improves the internal layout of the refrigerator 100, resulting in a more aesthetically pleasing and neat overall appearance.

[0066] For example, in Figure 2In the example shown, two drawers 2 are provided, and the two drawers 2 have different widths in the width direction of the refrigerated inner container 11. The two drawers 2 are arranged near the center of the refrigerator 100 to facilitate users to access items. The guide rail bracket 3 is provided between the two drawers 2. The height of the two drawers 2 can be adjusted simultaneously by the guide rail bracket 3, which can ensure the height consistency of the two drawers 2 and keep the two drawers 2 parallel, making the cabinet more beautiful.

[0067] Specifically, a guide groove 21 is formed on one of the drawer 2 and the guide rail bracket 3, and a guide wheel 32 is provided on the other of the drawer 2 and the guide rail bracket 3. The guide wheel 32 slides with the guide groove 21, and the guide groove 21 extends along the thickness direction of the refrigerated liner 11. Figure 2 Alternatively, the drawer 2 is provided with a guide wheel, and the guide rail bracket 3 is formed with a guide groove (not shown).

[0068] The sliding engagement of the guide wheels 32 and the guide slots 21 allows the drawer 2 to move more smoothly along the thickness of the refrigerated liner 11, making the push and pull operation of the drawer 2 easier and more labor-saving. Furthermore, the guide slots 21 extend along the thickness of the refrigerated liner 11, ensuring accurate movement of the drawer 2 along the thickness of the refrigerated liner 11 and preventing the drawer 2 from drifting during push and pull operations. Furthermore, the provision of the guide wheels 32 reduces frictional losses between the drawer 2 and the guide rail bracket 3, thereby extending the service life of the drawer 2.

[0069] According to the refrigerator 100 of the embodiment of the present invention, Figure 1-Figure 3 As shown, it includes a box body, a door body, at least one drawer 2 and a guide rail bracket 3.

[0070] Specifically, the box body includes a refrigerated inner container 11 and a back plate 12. The thickness direction of the refrigerated inner container 11 (for example, Figure 3 An opening 111 is formed on one side (in the front-to-back direction) of the refrigerated inner container 11, and a back panel 12 is provided on the other side in the thickness direction of the refrigerated inner container 11. A door is provided at opening 111 for opening and closing. The door and refrigerated inner container 11 together define a storage chamber 112. The drawer 2 is provided within the storage chamber 112; a portion of the guide rail bracket 3 is provided within the storage chamber 112 and is slidably connected to the drawer 2.

[0071] For example, in Figure 1-Figure 3 In the example shown, the back panel 12 and the door are respectively provided on opposite sides of the refrigerated liner 11 in the thickness direction, and the refrigerated liner 11 can be located above the back panel 12. The guide rail bracket 3 is generally an irregular plate-shaped structure, and a portion of the guide rail bracket 3 extends into the accommodating cavity 112, and is used for sliding connection with the drawer 2 to adjust the height of the drawer 2.

[0072] In addition, the refrigerator 100 further includes a rotating shaft 42, which is arranged in the height direction of the refrigeration liner 11 (for example, Figure 3 The rotating shaft 42 has at least one transmission gear 41, and the guide rail bracket 3 has at least one rack portion 31. The rack portion 31 is located outside the refrigerated inner container 11 and extends along the height of the refrigerated inner container 11. The rack portion 31 meshes with the transmission gear 41. The transmission gear 41 rotates to drive the guide rail bracket 3 and the drawer 2 to move along the height of the refrigerated inner container 11.

[0073] For example, in Figure 1-Figure 3 In the example shown, two rotating shafts 42 are provided, and two corresponding rack portions 31 are provided on the guide rail bracket 3. When the rotating shaft 42 rotates, the transmission gear 41 rotates, which in turn drives the rack portion 31 to move linearly along the height of the refrigerated liner 11. Because the guide rail bracket 3 is connected to the drawer 2, it can drive the guide rail bracket 3 and the drawer 2 to move along the height of the refrigerated liner 11. Adjusting the position of the drawer 2 in the height direction of the refrigerated liner 11 in this way allows the drawer 2 to always remain parallel to the refrigerated liner 11, preventing the drawer 2 from tilting, thereby improving the overall aesthetics of the refrigerator 100.

[0074] Moreover, the arrangement of the transmission gear 41 and the rack portion 31 can avoid the time-consuming and labor-intensive process of repeatedly adjusting the foaming mold, while reducing production costs. The arrangement of the rotating shaft 42 in the refrigerated inner tank 11 can better utilize the space of the accommodating cavity 112, thereby improving space utilization.

[0075] According to the refrigerator 100 of the present invention, a guide rail bracket 3, a rotating shaft 42 and a transmission gear 41 are arranged in the refrigerated inner tank 11, and a rack portion 31 is arranged on the outside of the refrigerated inner tank 22, and the rack portion 31 of the guide rail bracket 3 is engaged with the transmission gear 41 on the rotating shaft 42. Thus, the position of the drawer 2 in the height direction of the refrigerated inner tank 11 can be adjusted, and during the adjustment process, the drawer 2 can always remain parallel to the refrigerated inner tank 11, avoiding the problem of tilting of the drawer 2, thereby improving the overall aesthetics of the refrigerator 100, and avoiding repeated adjustment of the foaming mold, saving time and effort and having low production costs.
