Detailed Implementation

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0037] In daily life, many household items are equipped with sliding doors, such as drawers on refrigerators, dishwashers, washing machines, or storage cabinets, to improve space utilization and user convenience. However, these doors are prone to tilting during frequent opening and closing, which can cause problems such as cold water leakage in refrigerators or poor sealing in dishwashers, resulting in a poor user experience.

[0038] Taking French-door refrigerators as an example, the freezer compartment of a French-door refrigerator typically features multiple wide drawers, giving it ample lateral space, which has made it popular with many consumers. Usually, the freezer door and drawers are integrated, allowing users to directly open or close the drawers by pushing and pulling the freezer door. The door also helps to seal the gap between the drawer and the refrigerator body, preventing cold air leakage. However, with repeated use, the drawers are prone to tilting relative to the refrigerator body due to uneven force during frequent opening and closing. This causes the drawer door to also tilt relative to the refrigerator body, resulting in a poorly closed freezer door and cold air leakage. This not only reduces the refrigerator's freezing efficiency but also increases energy consumption, leading to a poor user experience.

[0039] Therefore, this application provides a door adjustment component capable of adjusting the tilt angle of the door to improve user satisfaction. It is understood that the door adjustment component provided in this application is not limited to drawer mechanisms or refrigerators, but can also be applied to any device, such as dishwashers or washing machines, where users have a need to improve door tilt; this application makes no limitation.

[0040] The door adjustment assembly provided in this application will now be described in conjunction with the accompanying drawings.

[0041] See Figures 1 to 4This application provides a door adjustment assembly 10, including a door bracket 11, a guide rail bracket 12, and an adjusting member 14. The door bracket 11 includes a door mounting portion 111 and an assembly portion 112 connected to the door mounting portion 111, the assembly portion 112 being disposed along the thickness direction of the door mounting portion 111. The guide rail bracket 12 includes a guide rail mounting portion 121 and a mating portion 122 connected to the guide rail mounting portion 121, the length direction of the guide rail mounting portion 121 being disposed along the thickness direction of the door mounting portion 111. The mating portion 122 is movably connected to the assembly portion 112, and one of the assembly portion 112 and the mating portion 122 is provided with an adjusting groove 13. The adjusting member 14 is located within the adjusting groove 13 and is rotatably connected to the other of the assembly portion 112 and the mating portion 122, allowing the adjusting member 14 to rotate eccentrically relative to the adjusting groove 13.

[0042] It should be noted that the door bracket 11 is used to mount the door body 31. The door body 31 can be connected to the door mounting portion 111 of the door bracket 11, and the assembly portion 112 of the door bracket 11 can be connected to the guide rail bracket 12, so that the door body 31 can move along the guide rail to have an open or closed state. The thickness direction of the door mounting portion 111 can be set along the front-back direction shown in the figure, and correspondingly, the thickness direction of the door body 31 is also set along the front-back direction shown in the figure. It is understood that the door mounting portion 111 and the door body 31 can be connected by snap-fit, threaded connection, adhesive bonding, or welding, etc., and this application does not impose any restrictions.

[0043] The guide rail bracket 12 is used to connect the door bracket 11 and the guide rail. The guide rail mounting part 121 of the guide rail bracket 12 can be connected to the guide rail and can reciprocate relative to the guide rail, so that the door bracket 11 can drive the door body 31 to reciprocate, thereby allowing the door body 31 to have an open state and a closed state. The mating part 122 of the guide rail bracket 12 is movably connected to the assembly part 112 of the door bracket 11 to adjust the relative position of the door bracket 11 and the guide rail bracket 12, thereby facilitating the adjustment of the tilt angle of the door body 31. Understandably, the length direction of the guide rail mounting part 121 can be along the front-back direction shown in the figure, and the door body 31 can reciprocate along the front-back direction shown in the figure, thereby switching the open state and the closed state of the door body 31.

[0044] To facilitate adjustment of the relative positions of the door bracket 11 and the guide rail bracket 12, one of the assembly part 112 and the mating part 122 is provided with an adjustment groove 13, and the other of the assembly part 112 and the mating part 122 is provided with a rotatable adjustment member 14, which is eccentrically positioned relative to the adjustment groove 13. When the adjustment member 14 rotates eccentrically within the adjustment groove 13, it can press against the inner wall of the adjustment groove 13, thereby pushing the assembly part 112 and the mating part 122 to swing relative to each other, changing the relative angle between the door bracket 11 and the guide rail bracket 12, and thus adjusting the tilt angle of the door body 31.

[0045] Thus, the door adjustment assembly 10 provided in this application can adjust the swing angle of the door bracket 11 and the guide rail bracket 12 by eccentric rotation of the adjusting member 14, thereby adjusting the tilt angle of the door 31. Essentially, during use, the door adjustment assembly 10 provided in this application only requires rotating the adjusting member 14 to adjust the tilt angle of the door 31, thereby improving the tilt problem of the door 31 and enhancing the user experience.

[0046] In some embodiments, when the door bracket 11 is connected to the guide rail bracket 12, the door mounting part 111 can limit the guide rail mounting part 121 in the front-to-back direction, and the assembly part 112 can limit the guide rail mounting part 121 in the left-to-right direction. When the door adjustment assembly 10 is installed on the drawer device, the drawer housing 32 can be connected between the door bracket 11 and the guide rail bracket 12, and the drawer housing 32 can press against the top of the guide rail bracket 12 to limit the guide rail mounting part 121 in the vertical direction, so that the guide rail bracket 12 can move smoothly along the guide rail and prevent derailment.

[0047] See Figure 3 and Figure 4 In some embodiments, to facilitate the installation of the adjusting member 14, one of the assembly part 112 and the mating part 122 that does not have an adjusting groove 13 may have an adjusting hole 1226. For example, the assembly part 112 has an adjusting groove 13, and the mating part 122 has an adjusting hole 1226. After the assembly part 112 and the mating part 122 are connected, the adjusting hole 1226 can be located within the adjusting groove 13 and eccentrically positioned relative to the adjusting groove 13, and the adjusting member 14 can be rotatably connected to the adjusting hole 1226. Thus, by eccentrically positioning the adjusting hole 1226 relative to the adjusting groove 13 and then rotatably installing the adjusting member 14 into the adjusting hole 1226, the eccentric positioning of the adjusting member 14 relative to the adjusting groove 13 can be achieved.

[0048] In some embodiments, to facilitate the rotatable connection between the adjusting member 14 and the adjusting hole 1226, the adjusting member 14 may include an adjusting screw, and the adjusting hole 1226 may include a threaded hole, so as to achieve a rotatable fit through the threaded connection between the adjusting screw and the threaded hole.

[0049] In other embodiments, the adjusting member 14 may include a rotating portion and an eccentric portion connected to the rotating portion. The rotating portion is rotatably connected to the mating portion 122, and the eccentric portion is located within the adjusting groove 13 and is eccentrically positioned relative to the adjusting groove 13. Thus, the eccentric positioning of the adjusting member 14 and the adjusting groove 13 can also be achieved through the structural shape of the eccentric portion itself. For example, the rotating portion of the adjusting member 14 can be rotatably connected to the mating portion 122 through the adjusting hole 1226. The distance between the eccentric portion of the adjusting member 14 and the inner walls of the adjusting groove 13 can be set differently to form an eccentric positioning. In this way, the eccentric positioning between the adjusting member 14 and the adjusting groove 13 can be achieved using the structural shape of the eccentric portion. Furthermore, when the adjusting member 14 is eccentrically positioned with the adjusting groove 13 through the eccentric portion, the rotating portion of the adjusting member 14 can be located at the center or eccentric position of the adjusting groove 13; this application does not impose any limitations on this.

[0050] See Figure 3 When the adjustment groove 13 is located in the assembly part 112, the adjustment groove 13 may include a first groove sidewall 131 and a second groove sidewall 132 spaced apart along the thickness direction of the door mounting part 111, a groove bottom wall 133 connecting the first groove sidewall 131 and the second groove sidewall 132, and a groove opening 134 opposite to the groove bottom wall 133. In this configuration, the groove opening 134 of the adjustment groove 13 opens downward, allowing the adjustment member 14 to enter the adjustment groove 13 through the groove opening 134, so as to facilitate the assembly of the adjustment member 14 between the door bracket 11 and the guide rail bracket 12.

[0051] See Figures 2 to 4 To increase the connection area between the assembly part 112 and the mating part 122, the assembly part 112 includes a first connecting part 1121 and a second connecting part 1122 connected sequentially along the direction from the groove opening 134 to the bottom wall 133 of the groove. The first connecting part 1121 protrudes from the second connecting part 1122 along the thickness direction of the door mounting part 111, and the adjusting groove 13 is located in the first connecting part 1121. The mating part 122 includes a first connecting mating part 1221 and a second connecting mating part 1222 connected to the first connecting mating part 1221. The first connecting part 1121 is movably connected to the first connecting mating part 1221, and the second connecting part 1122 is movably connected to the second connecting mating part 1222. The adjusting member 14 is located in the first connecting mating part 1221.

[0052] It should be noted that the first connecting portion 1121 and the first connecting mating portion 1221 are used to increase the connection area between the assembly portion 112 and the mating portion 122 in the front-rear direction, and the second connecting portion 1122 and the second connecting mating portion 1222 are used to increase the connection area between the assembly portion 112 and the mating portion 122 in the vertical direction. This arrangement improves the connection stability between the assembly portion 112 and the mating portion 122 by increasing the connection area, thereby increasing the load-bearing capacity of the door adjustment assembly 10.

[0053] See Figures 2 to 4 In some embodiments, the first connecting part 1121 is provided with a first connecting flange 1123 on the side near the bottom wall 133 of the groove, and the first connecting mating part 1221 is provided with a first mating flange 1223 opposite to the first connecting flange 1123, so as to increase the connection area between the assembly part 112 and the mating part 122 in the left and right direction through the first connecting flange 1123 and the first mating flange 1223.

[0054] Furthermore, after the assembly part 112 is connected to the mating part 122, the first connecting flange 1123 and the first mating flange 1223 press against each other to restrict the relative installation position of the door bracket 11 and the guide rail bracket 12 in the vertical direction.

[0055] See Figures 2 to 4 In some embodiments, the second connecting portion 1122 is provided with a second connecting flange 1124 on the side opposite to the door mounting portion 111, and the second connecting mating portion 1222 is provided with a second mating flange 1224 opposite to the second connecting flange 1124, so as to increase the connection area between the mounting portion 112 and the mating portion 122 in the left-right direction through the second connecting flange 1124 and the second mating flange 1224.

[0056] Furthermore, after the assembly part 112 is connected to the mating part 122, the second connecting mating part 1222 is located between the door mounting part 111 and the second connecting flange 1124, which can limit the relative installation position of the door bracket 11 and the guide rail bracket 12 in the front-to-back direction.

[0057] See Figure 2 and Figure 3 In some embodiments, the door bracket 11 is further provided with a load-bearing flange 1126 connected to the door mounting part 111 and spaced apart from the first connecting flange 1123. The load-bearing flange 1126 can be used to support the door body 31 and / or drawer to increase the connection area between the door body adjustment assembly 10 and the door body 31 and / or drawer, thereby improving the load-bearing capacity.

[0058] In some embodiments, to facilitate the movable connection between the door bracket 11 and the guide rail bracket 12, the door body adjustment assembly 10 further includes at least one limiting member and at least one limiting mating member corresponding to the at least one limiting member. The at least one limiting member is located in one of the assembly part 112 and the mating part 122, and the at least one limiting mating member is located in the other of the assembly part 112 and the mating part 122. Each limiting member is movably connected to each limiting mating member.

[0059] Understandably, the limiting component may include one or a combination of limiting structures such as limiting hole, limiting groove and limiting flange, and the limiting mating component may include one or a combination of limiting structures such as limiting post, limiting block and mating flange, and this application does not impose any restrictions.

[0060] See Figures 1 to 4 As one example, at least one limiting member includes a first limiting member 15 located on the first connecting flange 1123. At least one limiting mating member includes a first limiting mating member 16 located on the first mating flange 1223, and the first limiting member 15 is movably connected to the first limiting mating member 16.

[0061] Understandably, the first limiting member 15 may include a first limiting hole, and the first limiting mating member 16 may include a limiting post. The limiting post and the first limiting hole may be configured for a clearance fit, allowing the limiting post to rotate around the axis 151 of the first limiting hole and / or move along the axis 151 of the first limiting hole within the first limiting hole, thereby achieving a movable connection between the door bracket 11 and the guide rail bracket 12. With this configuration, when the adjusting member 14 rotates within the adjusting groove 13, the door bracket 11 and the guide rail bracket 12 can use the mating structure of the first limiting member 15 and the first limiting mating member 16 as a fulcrum to adjust the relative position of the door bracket 11 and the guide rail bracket 12 to adapt to the adjustment of the tilt angle of the door body 31.

[0062] In some embodiments, to expand the adjustment range of the tilt angle of the door body 31, the axial direction of the first limiting hole can be set along the depth direction of the adjusting groove 13, and the depth direction of the adjusting groove 13 can be set along the vertical direction in the figure. The first limiting hole and the adjusting groove 13 can also be aligned sequentially along the horizontal direction in the figure.

[0063] See Figures 1 to 4 As another example, at least one limiting member includes a second limiting member 17 located in the second connecting portion 1122, and at least one limiting mating member includes a second limiting mating member 18 located in the second connecting mating portion 1222, with the second limiting member 17 and the second limiting mating member 18 being movably connected.

[0064] With this configuration, when the adjusting member 14 rotates within the adjusting groove 13, the door bracket 11 and the guide rail bracket 12 can use the mating structure of the second limiting member 17 and the second limiting mating member 18 as the movable fulcrum, thereby adjusting the relative position of the door bracket 11 and the guide rail bracket 12 to adapt to the tilt angle of the door body 31.

[0065] Understandably, the second limiting member 17 includes a second limiting hole, and the axial direction of the second limiting hole is provided along the thickness direction of the assembly portion 112. The second limiting mating member 18 may include a limiting post that has a clearance fit with the second limiting hole.

[0066] Furthermore, when the door bracket 11 and the guide rail bracket 12 can use the mating structure of the second limiting hole and the second limiting fitting 18 as the movable fulcrum, the second limiting hole and the adjustment groove 13 can be aligned sequentially in the vertical direction in the figure, thereby facilitating the adjustment of the relative position of the door bracket 11 and the guide rail bracket 12 to adapt to the adjustment of the tilt angle of the door body 31.

[0067] Understandably, for the movable connection between the door bracket 11 and the guide rail bracket 12 in this application, the mating structure of the first limiting member 15 and the first limiting mating member 16 can serve as the first movable fulcrum, and the first movable fulcrum is located at the first connection. The mating structure of the second limiting member 17 and the second limiting mating member 18 can serve as the second movable fulcrum, and the second movable fulcrum is located at the second connection 1122. Depending on the different positions of the two movable fulcrums between the door bracket 11 and the guide rail bracket 12, the door body adjustment assembly 10 can have different adjustment ranges for the tilt angle of the door body 31. For example, if the adjustment range of the tilt angle of the door body 31 at the first movable fulcrum is θ1, and the adjustment range of the tilt angle of the door body 31 at the second movable fulcrum is θ2, then θ1 can be greater than θ2. Thus, according to the adjustment range requirement of the tilt angle of the door body 31, the door body adjustment assembly 10 can be selected to have either the first movable fulcrum or the second movable fulcrum, and this application does not impose any restrictions.

[0068] Of course, in other embodiments, the door adjustment assembly 10 may also be provided with a first movable fulcrum and a second movable fulcrum, so that the door adjustment assembly 10 can mutually limit each other according to the different angle adjustment ranges of the first movable fulcrum and the second movable fulcrum, thereby limiting the swing amplitude of the door bracket and preventing excessive tilt correction of the door bracket. Specifically, taking the first limiting member 15 including a first limiting hole and the second limiting member 17 including a second limiting hole as an example. When the door bracket 11 and the guide rail bracket 12 adjust their relative positions with respect to the first movable fulcrum, the second limiting hole can be set as a strip hole, so that the second limiting mating member 18 can have a range of movement within the second limiting hole, so that the door adjustment assembly 10 can both adjust the tilt angle of the door 31 by rotating with respect to the first movable fulcrum and limit the rotation range of the door 31 by rotating with respect to the first movable fulcrum using the second limiting hole. Understandably, the second limiting fitting 18 can be a limiting post that slides in the second limiting hole. The second limiting fitting 18 can also be set as an insertion hole corresponding to the second limiting hole, and the diameter of the second limiting hole is larger than the diameter of the insertion hole. Then, by assembling a pin or other connecting parts in the insertion hole, the pin can slide in the second limiting hole to limit the tilt angle of the door body 31.

[0069] The following will combine Figure 5 and Figure 6 The process of adjusting the tilt angle of the door 31 by the door adjustment component 10 provided in this application is further explained.

[0070] See Figure 5 and Figure 6 , Figure 5 The door support 11 shown is tilted, and the corresponding door body 31 is also tilted. Figure 6 The door support 11 shown is in an untilted state, and the corresponding door body 31 is also in an untilted state. Figure 5 and Figure 6 The dashed line in the diagram represents a reference state where the door 31 is not tilted. When the distance between the door support 11 and the dashed line is equal at all points, it indicates that the door 31 is not tilted; otherwise, it indicates that the door 31 is tilted.

[0071] exist Figure 5 In the middle, the door bracket 11 and the guide rail bracket 12 use the first movable fulcrum between the first limiting member 15 and the first limiting mating member 16 as the rotation fulcrum. Because... Figure 5 The door bracket 11 is tilted, and the first connecting flange 1123 of the door bracket 11 is tilted relative to the first mating flange 1223 of the guide rail bracket 12, so that there is an angle between the axis 151 of the first limiting hole and the axis of the limiting post. When the adjusting member 14 is tilted... Figure 5 When arrow a is rotated clockwise, the adjusting member 14 can press against the second groove sidewall 132 to push the second groove sidewall 132 to swing forward clockwise, causing the door bracket 11 to swing forward clockwise relative to the guide rail bracket 12, thereby driving the door body 31 to swing forward. At this time Figure 5 In the middle, the distance d2 between the upper end of the door bracket 11 and the dotted line gradually decreases, while the distance d1 between the lower end of the door bracket 11 and the dotted line gradually increases, until d1 and d2 are adjusted to d0 respectively, so that the door bracket 11 achieves... Figure 6 The state shown as not tilted indicates that the door adjustment assembly 10 has adjusted the tilt angle of the door 31 to the state of not tilting.

[0072] Among them, the door bracket 11 is made of Figure 5 The status shown has been adjusted to Figure 6 During the process shown, the upper and lower ends of the door bracket 11 can be simultaneously adjusted in both the front-back and vertical directions by the eccentric rotation of the adjusting member 14. Understandably, the front and rear of the door body 31 can be adjusted to an untilted state, meaning the door body 31 can remain vertical to fit snugly against the surrounding mounting structure, thus improving the sealing performance of the door body 31. Simultaneously, the upper and lower ends of the door body 31 can also be adjusted to an untilted state to prevent the upper and lower ends of the door body 31 from pressing against the surrounding structure and hindering the sliding of the door body 31.

[0073] Understandably, in the door support 11 by Figure 5The status shown has been adjusted to Figure 6 During the process shown, the second limiting hole can be set as an elliptical hole or a strip-shaped hole so that the second limiting fitting 18 can move within the second limiting hole to avoid interfering with the straightening of the door body 31. Furthermore, by reasonably setting the size of the second limiting hole, the swing range of the door bracket 11 can also be limited through the second limiting hole to prevent the door bracket 11 from being over-straightened.

[0074] Understandably, when Figure 5 When the adjusting member 14 is rotated counterclockwise in the direction opposite to arrow a, it can press against the first groove sidewall 131 to push the second groove sidewall 132 to swing counterclockwise backward, causing the door bracket 11 to swing counterclockwise backward relative to the guide rail bracket 12, thereby driving the door body 31 to swing backward. The door body adjusting assembly 10 can select to rotate the adjusting member 14 clockwise or counterclockwise according to the tilt state of the door body 31.

[0075] In some embodiments, the depth dimension of the adjustment groove 13 can be set to be greater than the dimension of the adjustment member 14 along the depth direction of the adjustment groove 13, so that the adjustment member 14 can not press against the bottom wall 133 of the groove during rotation, thereby avoiding large fluctuations of the door bracket 11 in the vertical direction, so as to avoid the door 31 being stuck by the external structure in the vertical direction, causing the door 31 to be unable to open and close smoothly.

[0076] See Figures 1 to 6 In some embodiments, after adjusting the relative positions of the door bracket 11 and the guide rail bracket 12, the door body adjustment assembly 10 further includes a fastener 19 to facilitate fixing the door bracket 11 and the guide rail bracket 12. One of the assembly part 112 and the mating part 122 is provided with a connecting groove 1125, and the other of the assembly part 112 and the mating part 122 is provided with a connecting hole 1225. The connecting hole 1225 is located in the connecting groove 1125, and the fastener 19 is detachably connected to the connecting groove 1125 and the connecting hole 1225.

[0077] Understandably, the fastener 19 includes a fastening screw, and the inner wall of the connecting hole 1225 may be threaded. A detachable connection is achieved by connecting the fastening screw with the threaded connection of the connecting hole 1225. This application does not limit this. With this configuration, the door bracket 11, which has been adjusted in position, can be fixed to the guide rail bracket 12 by the fastener 19, so that the door 31 can be used in a non-tilted state.

[0078] See Figure 7 and Figure 8In addition to the aforementioned door adjustment assembly 10, this application also provides a refrigerator 1 equipped with the aforementioned door adjustment assembly 10. As an example, the refrigerator 1 includes a cabinet assembly 20, a drawer assembly 30, and any one of the aforementioned door adjustment assemblies 10. The cabinet assembly 20 has a cooling compartment 21, and a guide rail bracket 12 is movably connected to the inner wall of the cooling compartment 21. The drawer assembly 30 includes a door 31 connected to a door bracket 11 and a box 32 connected to the door 31, with the box 32 located between the door bracket 11 and the guide rail bracket 12. The guide rail bracket 12 is capable of reciprocating relative to the cabinet assembly 20, allowing the drawer assembly 30 to have a closed state retracted into the cooling compartment 21 and an open state extended outside the cooling compartment 21.

[0079] It should be noted that the refrigeration compartment 21 includes various compartments such as a freezer compartment, a refrigerator compartment, and a variable temperature compartment, and this application does not limit this. The cabinet assembly 20 includes an inner liner 22, and the refrigeration compartment 21 is located in the inner liner 22. The inner wall of the inner liner 22 may be provided with guide rails to facilitate the connection of the guide rail bracket 12. The box body 32 is used to store the user's items to be frozen, and the door 31 can seal the gap between the box body 32 and the inner liner 22, thereby preventing cold leakage from the refrigeration compartment 21.

[0080] When the refrigerator 1 provided in this application uses the door adjustment assembly 10 to adjust the tilt angle of the door 31, it is only necessary to rotate the adjustment component 14. The eccentric rotation of the adjustment component 14 drives the door bracket 11 to swing the door 31 of the drawer assembly 30, so that the upper and lower ends of the door 31 can move closer to or further away from the inner liner 22 along the push-pull direction of the drawer assembly 30. This fits the door 31 with the inner liner 22, sealing the gap between the door 31 and the inner liner 22, preventing cold leakage from the refrigeration compartment 21 of the refrigerator 1, improving the freezing effect of the refrigerator 1 and reducing energy consumption. At the same time, the swing of the door 31 will also move the upper and lower ends of the door 31 along the depth direction of the drawer assembly 30, so as to prevent the multiple drawer doors 31 of the refrigerator 1 from pressing against each other due to tilting, thereby allowing the drawer doors 31 of the refrigerator 1 to open and close smoothly.

[0081] In some embodiments, this application also provides a drawer device (not shown in the figures) with a door adjustment assembly 10. As an example, the drawer device includes a housing assembly, a drawer assembly 30, and any of the aforementioned door adjustment assemblies 10. The housing assembly has a receiving cavity, and a guide rail bracket 12 is movably connected to the inner wall of the receiving cavity. The drawer assembly 30 includes a door 31 connected to a door bracket 11 and a housing 32 connected to the door 31, with the housing 32 located between the door bracket 11 and the guide rail bracket 12. The guide rail bracket 12 is capable of reciprocating relative to the housing assembly, allowing the drawer assembly 30 to have a closed state retracted into the receiving cavity and an open state extended outside the receiving cavity.

[0082] Understandably, drawer devices include cabinets with drawers, tables with drawers, etc., and this application does not impose any limitations. The drawer device can adjust the relative distance between the door 31 of the drawer assembly 30 and the housing assembly by means of the door adjustment component 10 connected between the drawer assembly 30 and the housing assembly, so as to prevent the door 31 of the drawer assembly 30 from tilting, thereby improving the sealing performance of the drawer and the smoothness of the drawer pulling.

[0083] The technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings. All modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
