Abstract
Description
Technical Field
[0001] This application relates to the field of cabinet partition technology, and in particular to a retractable cabinet partition. Background Technology
[0002] Dividers, as a common cabinet partitioning tool, are widely used to divide the interior cavities of various drawers and cabinets to meet the needs of classifying and storing different items. To improve the versatility of dividers and make them adaptable to drawer cavities of different sizes, dividers on the market currently typically adopt a telescopic design. These telescopic dividers mainly consist of a telescopic body and end plates at both ends. Currently, the end plates of telescopic dividers on the market are all set as fixed structures. This fixed end plate design has significant problems in practical applications. On the one hand, if the end plate is deformed or has poor manufacturing precision, it will cause the end plate to not fit tightly against the drawer wall, resulting in an unstable divider installation. On the other hand, the fixed end plate design makes the divider occupy a large space, which is not conducive to storage and transportation.

[0024] This utility model proposes a retractable cabinet partition.
[0025] In this embodiment of the utility model, please refer to Figures 1 to 4 The retractable cabinet partition includes a first partition 100, a second partition 200, a first end plate 300, and a second end plate 400. The first partition 100 and the second partition 200 both extend into a long strip shape; the first end plate 300 is rotatably connected to one end of the first partition 100, and the second end plate 400 is rotatably connected to one end of the second partition 200; the other ends of the first partition 100 and the other ends of the second partition 200 are slidably connected in their length direction. One of the first partition 100 and the second partition 200 is provided with a positioning structure 110 extending along its length direction. The positioning structure 110 includes a plurality of positioning parts 111 arranged along the length direction of the first partition 100. The other is provided with a stop structure 210 that cooperates with the positioning parts 111 to stop. The stop structure 210 can be switched between two adjacent positioning parts 111.
[0026] In this embodiment, the first partition 100, the second partition 200, the first end plate 300, and the second end plate 400 can be made of materials such as plastic, metal, or wood, depending on actual needs. It should be noted that the first partition 100 and the second partition 200 are slidably connected in their length direction; that is, the first partition 100 and the second partition 200 slide relative to each other in the length direction, but are connected at the upper limit in the thickness direction of the partitions to ensure that the partitions maintain linear movement during expansion and contraction. There are many ways to limit the first partition 100 and the second partition 200 in the thickness direction. For example, in some embodiments, a limiting lug can be provided on the edge of one of the first partition 100 and the second partition 200 to form a groove with the surface of the partition, allowing the edge of the other partition to slidably reside within the groove. In other embodiments, one of the first partition 100 and the second partition 200 can be configured as a sleeve with a slot, allowing the other partition to slide into the sleeve. The sliding connection method of the first partition 100 and the second partition 200 can be designed according to actual needs, and no specific limitation is made here.
[0027] The positioning structure 110 stops the first partition 100 and the second partition 200 when they slide relative to each other. The multiple positioning parts 111 can be specifically configured as multiple grooves, multiple protrusions, etc., for positioning and initially stopping the stop structure 210. The stop structure 210 is a limiting component that cooperates with the positioning parts 111. The stop structure 210 can specifically adopt elastic buckles, elastic glass beads, etc., and can switch between adjacent positioning parts 111 while cooperating with the positioning parts 111. Thus, multi-level adjustment of the partition length can be achieved by switching the engagement position of the stop structure 210 and the positioning parts 111.
[0028] The first end plate 300 and the first partition 100, and the second end plate 400 and the second partition 200, can be rotatably connected by means of a pivot or hinge. It is understood that the rotation axes of the first end plate 300 and the second end plate 400 both extend along the width direction of the partition. Generally, the first end plate 300 and the second end plate 400 are perpendicular to the first partition 100 and the second partition 200. By making the first end plate 300 and the second end plate 400 rotatable, the included angle between the surfaces of the first end plate 300 and the second end plate 400 and the first partition 100 and the second partition 200 can be adjusted.
[0029] This utility model's retractable cabinet partition allows for multi-level adjustment of the partition length by slidably connecting the first partition 100 and the second partition 200, with the first partition 100 and the second partition 200 achieving sliding positioning and stopping via a positioning structure 110 and a stop structure 210. This adapts to cabinets of different sizes, improving the partition's versatility. Furthermore, by allowing the first end plate 300 to rotate relative to the first partition 100 and the second end plate 400 to rotate relative to the second partition 200, compared to a fixed end plate, even if the end plates are deformed or have low manufacturing precision, the angles of the first end plate 300 relative to the first partition 100 and the second end plate 400 relative to the second partition 200 can be adjusted to ensure that the first end plate 300 and the second end plate 400 always remain in close contact with the inner wall of the drawer. In other words, the first end plate 300 and the second end plate 400 can adaptively adjust their angles to fit the cabinet wall, thereby improving the partition's installation stability. In addition, since the first end plate 300 can rotate relative to the first partition 100 and the second end plate 400 can rotate relative to the second partition 200, when storing, the first end plate 300 and the second end plate 400 can be rotated to be close to the first partition 100 or the second partition 200, so as to effectively reduce the space occupied by the entire retractable cabinet partition, which is more conducive to storage and transportation.
[0030] In one embodiment, such as Figure 2 As shown, the first end plate 300 can be rotated to be adjacent to or abut against at least one surface of the first partition 100; the second end plate 400 can be rotated to be adjacent to or abut against at least one surface of the second partition 200.
[0031] "Adjacent" or "fitting" refers to the parallel or nearly parallel spatial relationship between the end plate and the partition plate surface after rotation. Specifically, when the first end plate 300 rotates to be adjacent to the first partition plate 100, and the second end plate 400 rotates to be adjacent to the second partition plate 200, the distance between the surface of the first end plate 300 and the first partition plate 100 is less than the thickness of the first partition plate 100, for example, the distance between the surface of the first end plate 300 and the first partition plate 100 is less than 2 mm, and the distance between the surface of the second end plate 400 and the second partition plate 200 is less than the thickness of the second partition plate 200, for example, the distance between the surface of the first end plate 300 and the first partition plate 100 is less than 2 mm.
[0032] When the first end plate 300 can rotate to be adjacent to or abut against the two side plates of the first partition 100, that is, the first end plate 300 can freely and flexibly adjust the rotation angle, the rotation angle range of the first end plate 300 is approximately 0~180 degrees. When the second end plate 400 can rotate to be adjacent to or abut against the two side plates of the second partition 200, that is, the second end plate 400 can freely and flexibly adjust the rotation angle, the rotation angle range of the second end plate 400 is approximately 0~180 degrees.
[0033] Specifically, when the end plate is in the unfolded state, it is perpendicular to or nearly 90 degrees to the partition, abutting against the inner wall of the cabinet. When storage or transportation is required, the end plate can rotate around the pivot to a state parallel to or flush with the partition surface. That is, the rotating structure allows for flexible adjustment of the angles of the first end plate (300°) and the second end plate (400°). During installation, the end plate angle can be adjusted according to the actual shape of the inner wall of the cabinet to ensure tight contact between the end plate and the inner wall, adapting to cabinet cavities of different sizes and shapes, thus enhancing the versatility and flexibility of the partition. When the end plate is flush with the partition surface, the overall thickness of the partition is minimized, effectively reducing the overall volume and space occupied by the partition, making it easier to stack, store, and transport.
[0034] In one embodiment, please refer to Figures 4 to 10 One end of the first partition 100 is provided with a first rotating shaft 120, and the first end plate 300 is provided with two first lugs 310 corresponding to and rotatably engaged with the two ends of the first rotating shaft 120; the first rotating shaft 120 is provided with a first positioning groove 320 on one side away from the peripheral wall of the first partition 100 and the first end plate 300, and the other side is provided with a first positioning protrusion 121 adapted to the first positioning groove 320; the first end plate 300 can rotate relative to the first partition 100 until the first positioning protrusion 121 engages with the first positioning groove 320 and disengages from the first positioning groove 320; and / or, The second partition 200 has a second rotating shaft 220 at one end, and the second end plate 400 has two second lugs 410 that correspond to the two ends of the second rotating shaft 220 and can be rotatably engaged. The second rotating shaft 220 is away from the peripheral wall of the second partition 200 and the second end plate 400 has a second positioning groove 420 on one side and a second positioning protrusion that is adapted to the second positioning groove 420 on the other side. The second end plate 400 can rotate relative to the second partition 200 until the second positioning protrusion engages with the second positioning groove 420 and disengages from the second positioning groove 420.
[0035] In this embodiment, the first rotating shaft 120 serves to provide a rotation fulcrum for the first end plate 300. Specifically, the first rotating shaft 120 is integrally formed with the first partition plate 100 to ensure structural strength. Of course, in some embodiments, the first rotating shaft 120 can also be rotatably connected to the first partition plate 100. The first lug 310 is a protrusion structure provided on both sides of the first end plate 300, used to cooperate with the first rotating shaft 120 to form a rotatable hinge structure.
[0036] The first positioning groove 320 can be a rectangular groove or a hemispherical groove. The first positioning protrusion 121 is adapted to the first positioning groove 320, for example, it can be a rectangular block, a wedge-shaped block, or a hemispherical protrusion. The number of the first positioning groove 320 and the first positioning protrusion 121 can be one or more. To improve the positioning reliability between the first end plate 300 and the first partition plate 100, optionally, multiple first positioning protrusions 121 and first positioning grooves 320 can be provided, and the multiple first positioning protrusions 121 are arranged at intervals along the length direction of the first rotating shaft 120.
[0037] The first positioning protrusion 121 or the first positioning groove 320 is positioned on the first rotating shaft 120 away from the peripheral wall of the first partition 100. Thus, when the first positioning protrusion 121 engages with the first positioning groove 320, the first end plate 300 and the first partition 100 are substantially perpendicular. Therefore, the first end plate 300 and the first partition 100 can be angle-locked through the mechanical engagement of the first positioning protrusion 121 and the first positioning groove 320, allowing the first end plate 300 to be accurately positioned and maintain its perpendicular position relative to the first partition 100. When it is necessary to fold or adjust the angle of the first end plate 300, the first positioning protrusion 121 can easily disengage from the first positioning groove 320 to avoid interfering with the rotation of the first end plate 300.
[0038] The connection relationship between the second rotating shaft 220, the second lug 410, the second positioning protrusion, the second positioning groove 420 and the second end plate 400 and the second partition 200, as well as the function between each component, are the same as those between the first rotating shaft 120, the first lug 310, the first positioning protrusion 121, the first positioning groove 320 and the first end plate 300 and the first partition 100. Therefore, the specific description of the second rotating shaft 220, the second lug 410, the second positioning protrusion and the second positioning groove 420 refers to the relevant description of the first rotating shaft 120, the first lug 310, the first positioning protrusion 121 and the first positioning groove 320 mentioned above, and will not be repeated here.
[0039] In one embodiment, such as Figures 1 to 7 As shown, a positioning structure 110 is provided on the upper and lower sides of the first partition 100 facing away from the second partition 200, and a stop structure 210 is provided on the upper and lower sides of the other side of the first partition 100 facing away from the first end plate 300. The second partition 200 has a positioning structure 110 on each of the upper and lower sides of the plate surface opposite to the first partition 100, and a stop structure 210 on each of the upper and lower sides of the other plate surface opposite to one end of the second end plate 400. The stop structure 210 on the first partition 100 cooperates with the positioning structure 110 on the second partition 200, and the stop structure 210 on the second partition 200 cooperates with the positioning structure 110 on the first partition 100.
[0040] In this embodiment, when the stop structures 210 on the upper and lower sides of the first partition 100 engage with the positioning parts 111 on the second partition 200, the stop structures 210 on the upper and lower sides of the second partition 200 simultaneously engage with the corresponding positioning parts 111 on the first partition 100, achieving bidirectional interlocking. By providing positioning structures 110 and stop structures 210 on both the upper and lower sides of the first partition 100 and the second partition 200, the first partition 100 and the second partition 200 form a multi-layered locking system, balancing the forces on both sides and the left and right ends of the partition surface, thus enhancing connection stability. Even if one side experiences wear or deformation, the other side can still maintain effective locking.
[0041] Furthermore, the stop structure 210 includes a bearing protrusion 211 extending outward along the plate surface of the first partition 100 or the second partition 200, and a fastening plate 212 bent from the end of the bearing protrusion 211 to extend along the plate surface. The inner wall surface of the fastening plate 212 is provided with a protrusion 213 that cooperates with the positioning part 111. The first partition 100 is inserted between the fastening plate 212 on the second partition 200 and the second partition 200, and the second partition 200 is inserted between the fastening member on the first partition 100 and the first partition 100.
[0042] The supporting protrusion 211 refers to a support structure extending vertically from the surface of the partition, which also serves to provide a mounting base for the snap-fit plate 212. To ensure structural strength, optionally, the supporting protrusion 211 on the first partition 100 is integrally formed with the first partition 100, and the supporting protrusion 211 on the second partition 200 is integrally formed with the second partition 200. By providing the supporting protrusion 211, the support area of the retractable cabinet partition during installation can be increased, thereby making the installation of the retractable cabinet partition more stable and reliable.
[0043] The snap-fit plate 212 refers to the clamping structure formed by bending the end of the supporting protrusion 211, which is used to form a sliding fit space with the partition, allowing the two sides of the partition to slide within the sliding space. Thus, the first partition 100 and the second partition 200 can be initially limited in the thickness direction by the stop structure 210, effectively preventing wobbling and displacement of the first partition 100 and the second partition 200 during sliding. The protrusion 213 refers to the protruding structure provided on the inner wall of the snap-fit plate 212, which is used to form a mechanical engagement with the positioning part 111 to limit the relative displacement of the first partition 100 and the second partition 200. The engagement of the protrusion 213 with the multiple positioning parts 111 on the positioning structure 110 forms a multi-point locking, allowing the two partitions to be positioned step by step during extension and retraction.
[0044] In one embodiment, please refer again Figures 1 to 7The first partition 100 has a first notch 130 on both the upper and lower sides of the end adjacent to the first end plate 300. The stop structure 210 on the second partition 200 can be installed and removed through the first notch 130. The first partition 100 has a first limiting protrusion 140 on the surface facing the second partition 200. The first limiting protrusion 140 has a first limiting surface 141 located on the side of the first notch 130 away from the first end plate 300. The end face of the second partition 200 abuts against the first limiting surface 141. The second partition 200 has a second notch 230 at both the upper and lower ends near the second end plate 400. The stop structure 210 on the first partition 100 can be installed and removed through the second notch 230. The second partition 200 has a second limiting protrusion 240 on the plate surface facing the second partition 200. The second limiting protrusion 240 has a second limiting surface 241 located on the side of the second notch 230 away from the second end plate 400. The end face of the first partition 100 abuts against the second limiting surface 241.
[0045] The first notch 130 refers to the opening area on the upper and lower sides of the end of the first partition 100, which forms the disassembly and assembly channel of the stop structure 210. The first limiting protrusion 140 refers to the blocking structure that partially protrudes from the surface of the first partition 100. The first limiting surface 141 is used to limit the displacement of the second partition 200 along the length direction, thereby preventing the second partition 200 from moving too far and falling out of the first notch 130. The definition and function of the second notch 230 and the second limiting protrusion 240 correspond to the first notch 130 and the first limiting protrusion 140, and will not be described again here.
[0046] Specifically, when the first partition 100 and the second partition 200 are slidably connected, when the end of the second partition 200 moves to the position of the first limiting surface 141 of the first limiting protrusion 140, the end face contacts the limiting surface to form a physical block, preventing the partition from sliding excessively and causing it to detach. At the same time, the first notch 130 and the second notch 230 are symmetrically distributed openings, allowing the stop structure 210 to be installed or removed through the notches, simplifying maintenance operations.
[0047] In one embodiment, such as Figures 1 to 4 , Figure 8 and Figure 9 The first limiting protrusion 140 also has a first guiding slope 142, which is inclined in the direction away from the first end plate 300 toward the side away from the first partition 100. The second limiting protrusion 240 also has a second guide slope 242, which is inclined in the direction away from the second end plate 400 toward the side away from the second partition 200.
[0048] In this embodiment, the first guide slope 142 refers to the inclined surface disposed on the first limiting protrusion 140, and the second guide slope 242 refers to the inclined surface disposed on the second limiting protrusion 240. The first guide slope 142 and the second guide slope 242 can reduce the friction area of the first partition 100 and the second partition 200 during assembly, thereby reducing the sliding resistance during assembly. The first guide slope 142 and the first limiting surface 141 can be formed by making the first limiting protrusion 140 a ramp structure.
[0049] In one embodiment, please refer to Figures 2 to 11 The first partition 100 includes a first main body plate 150 and a first connecting plate 160 connected to each other. The first main body plate 150 extends in a long strip shape along its length. The first connecting plate 160 and the first rotating shaft 120 are respectively disposed at both ends of the first main body plate 150. A stop structure 210 is provided on each of the upper and lower sides of the first connecting plate 160. A first deformation notch 170 is provided at the connection between the upper and lower edges of the first connecting plate 160 and the first main body plate 150. The first connecting plate 160 is provided with a first mounting hole 161 corresponding to the fastening plate 212; and / or, The second partition 200 includes a second main body plate 250 and a second connecting plate 260 connected to each other. The second main body plate 250 extends in a long strip shape along the length direction. The second connecting plate 260 and the second rotating shaft 220 are respectively disposed at both ends of the second main body plate 250. Two stop structures 210 are provided on the upper and lower sides of the second connecting plate 260. The upper and lower edges of the second connecting plate 260 and the second main body plate 250 are provided with second deformation notches 270. The second connecting plate 260 is provided with a second mounting hole 271 corresponding to the fastening plate 212.
[0050] In this embodiment, the first main body plate 150 refers to the elongated plate that forms the main supporting surface of the partition, and its extension length can be adjusted according to the internal cavity size of the cabinet. The first connecting plate 160 refers to the end structure connected to the end of the main body plate, used for the installation of the stop structure 210. The first deformation notch 170 refers to the groove structure provided at the connection between the connecting plate and the main body plate, specifically a U-shaped notch, used to facilitate the elastic deformation of the connecting plate during assembly to facilitate the cooperation between the stop structure 210 and the positioning structure 110. The first mounting hole 161 refers to the through hole structure opened on the connecting plate, specifically a stamped square hole for mold clamping. The functions of the second main body plate portion 250, the second connecting plate portion 260, the second deformation notch 270, and the second mounting hole 271 are the same as those of the first main body plate portion 150, the first connecting plate portion 160, the first deformation notch 170, and the first mounting hole 161. Therefore, the specific descriptions of the second main body plate portion 250, the second connecting plate portion 260, the second deformation notch 270, and the second mounting hole 271 are the same as those of the first main body plate portion 150, the first connecting plate portion 160, the first deformation notch 170, and the first mounting hole 161, and will not be repeated here.
[0051] Specifically, the first main body plate 150 and the second main body plate 250 are slidably connected to achieve telescopic adjustment, and the stop structure 210 provided on the connecting plate is engaged and locked with the positioning structure 110 of the other partition. During assembly, the deformation notch allows the connecting plate to undergo local elastic deformation to facilitate the disassembly and assembly of the first partition 100 and the second partition 200, avoiding damage to components caused by rigid assembly.
[0052] In one embodiment, such as Figures 1 to 4 , Figures 6 to 10 The first partition 100 has a positioning structure 110 on each of the upper and lower sides of the plate surface opposite to the second partition 200, and a stop structure 210 is provided on each of the upper and lower sides of the other plate surface opposite to the end of the first end plate 300. The second partition 200 has a positioning structure 110 on each of the upper and lower sides of the plate surface opposite to the first partition 100, and a stop structure 210 on each of the upper and lower sides of the other plate surface opposite to one end of the second end plate 400. The stop structure 210 on the first partition 100 cooperates with the positioning structure 110 on the second partition 200, and the stop structure 210 on the second partition 200 cooperates with the positioning structure 110 on the first partition 100. The peripheral wall of the first lug 310 is an arc surface, and the stop structure 210 on the second partition 200 has a clearance slope 214 on the side wall facing the first lug 310 to avoid the first end plate 300; and / or, The peripheral wall of the second lug 410 is an arc surface, and the stop structure 210 on the first partition 100 is provided with a clearance slope 214 on the side wall facing the second lug 410 to avoid the second end plate 400.
[0053] In this embodiment, when the stop structures 210 on the upper and lower sides of the first partition 100 engage with the positioning parts 111 on the second partition 200, the stop structures 210 on the upper and lower sides of the second partition 200 simultaneously engage with the corresponding positioning parts 111 on the first partition 100, achieving bidirectional interlocking. By providing positioning structures 110 and stop structures 210 on both the upper and lower sides of the first partition 100 and the second partition 200, the first partition 100 and the second partition 200 form a multi-layered locking system, balancing the forces on both sides and the left and right ends of the partition surface, thus enhancing connection stability. Even if one side experiences wear or deformation, the other side can still maintain effective locking.
[0054] The avoidance ramp 214 refers to the inclined guide surface provided on the side wall of the stop structure 210, used to avoid obstruction of the end plate when it is folded. Furthermore, when the first partition 100 and the second partition 200 slide relative to each other to their final positions, the avoidance ramp 214 can also adapt to the arc surface of the lug to avoid obstruction of the lug. This embodiment effectively solves the technical problem of interference between the end plate of the retractable partition and the adjacent stop structure 210 when folded, allowing the end plate to fit tightly against the partition when folded and stored, reducing packaging volume, while ensuring structural stability and smooth operation during use.
[0055] In one embodiment, the first end plate 300 and the second end plate 400 have the same structure and can be interchanged; the first partition 100 and the second partition 200 have the same structure and can be interchanged.
[0056] The term "same structure" refers to the end plates or partitions having basically or completely identical shapes, dimensions, and connection structures. The first partition 100 and the second partition 200 are slidably connected to each other via symmetrically distributed positioning structures 110 and stop structures 210. This solution, through standardized design, makes the first end plate 300 and the second end plate 400 interchangeable with the first partition 100 and the second partition 200. Therefore, during mold opening, the first partition 100 and the second partition 200 can be molded using the same set of molds, and the first end plate 300 and the second end plate 400 can be molded using the same set of molds, effectively reducing manufacturing costs.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
