CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims foreign priority of Chinese Patent Application No. 202520348950.7, filed on March 3, 2025 in the China National Intellectual Property Administration (CNIPA), the entire contents of which are hereby incorporated by reference in their entireties.TECHNICAL FIELD

[0002] The present utility model relates to the field of partitioning devices, and more particularly to a retractable drawer dividing device.BACKGROUND OF THE INVENTION

[0003] At present, drawers or drawer-like components are commonly provided in cabinets, household furniture, home appliances, and other products for the purpose of storing items. In everyday use, different items are often placed in the same drawer, resulting in a cluttered interior. This disorganization makes it difficult to retrieve specific items and prevents efficient use of drawer space. Furthermore, the accumulation of items over time leads to increasing disorder. Therefore, an auxiliary tool is needed to effectively divide the internal space of the drawer - this tool is referred to as a drawer partition device.

[0004] In response to growing end-user demand, some drawer partition devices have emerged on the market, capable of retractably adjusting the partition length based on drawer specifications. However, most of these devices feature complex structures, resulting in high production costs. The multi-component design also causes inefficiencies in assembly and a steep learning curve for installation. Additionally, such devices are prone to malfunction during use, compromising their intended function. For example, Chinese Patent Publication No. CN108968450A, titled “Retractable Drawer Divider,” discloses a device comprising a main partition body and an auxiliary partition body slidably fitted thereto. The main body includes a cavity extending in the longitudinal direction, into which one end of the auxiliary body is inserted and slidably engaged. A stop structure is provided between the main and auxiliary bodies to restrict relative motion when the two move toward each other to a set position. However, because this stop structure is located within the cavity and the device consists of numerous components, it poses challenges in terms of installation, manufacturing, and maintenance.

[0005] Accordingly, there is a need to optimize the structure of drawer partition devices to enhance reliability in use while improving operational convenience, ease of assembly, and flexibility of adjustment—making this a topic of significant practical importance.SUMMARY OF THE INVENTION

[0006] In view of the foregoing, the present utility model aims to provide a retractable drawer dividing device featuring a simple structure, reliable engagement, and convenient use.

[0007] To achieve the above-mentioned technical objective, the technical solution adopted by the present utility model is as follows:

[0008] A retractable drawer dividing device comprising a first partition plate and a second partition plate slidably connected at one end. A locking structure is provided between the first and second partition plates, the locking structure having a locked state and an unlocked state. In the locked state, the first and second partition plates are constrained and fixed relative to each other; in the unlocked state, the first and second partition plates are slidable relative to each other. An arcuate portion with an elastic structure is provided at the other end of the first partition plate and / or the second partition plate, the arcuate portion being configured to contact the side surface of the drawer.

[0009] In one possible embodiment, a gap is formed between the other end of the first and / or second partition plate and the arcuate portion, and a spring tab extending in a direction away from the arcuate portion is provided on the side of the arcuate portion adjacent to the gap.

[0010] In a preferred embodiment, the arcuate portions with elastic structures are provided at the other ends of both the first partition plate and the second partition plate.

[0011] In a further preferred embodiment, an EVA layer is provided on the outer side of the arcuate portion.

[0012] In a preferred embodiment, U-shaped first limiting portions are provided on both sides of one end of the first partition plate. A limiting zone is formed between the pair of first limiting portions, the limiting zone being configured to guide the first and second partition plates to slide relative to each other in the longitudinal direction. One end of the second partition plate passes through the limiting zone.

[0013] In another preferred embodiment, U-shaped second limiting portions are provided on both sides of one end of the second partition plate. The pair of second limiting portions are respectively configured to engage with both sides of the first partition plate, guiding the first and second partition plates to slide relative to each other in the longitudinal direction.

[0014] In a further preferred embodiment, the main bodies of both the first and second partition plates are formed as concave shell structures. A rack structure is provided along the inner wall of one side of the first partition plate in the longitudinal direction. An elastic extension portion is provided on one side of the end of the second partition plate corresponding to the rack structure, and the extension portion is provided with locking teeth engaged with the rack. The locking teeth and the rack structure cooperatively form the locking structure. A clearance gap is provided between the main body of the second partition plate and the extension portion, and a pressing block is further provided on one side of the extension portion.

[0015] In the locked state of the locking structure, the locking teeth are engaged with the rack structure, thereby constraining and fixing the first and second partition plates relative to each other.

[0016] In the unlocked state of the locking structure, the pressing block is actuated to deform the extension portion along the clearance gap, causing the locking teeth to disengage from the rack structure, thereby allowing the first and second partition plates to slide relative to each other.

[0017] In another preferred embodiment, a first guide groove is provided on the opposing side surface of the first partition plate relative to the second partition plate, and a corresponding first guide block in sliding engagement with the first guide groove is provided on the side surface of one end of the second partition plate.

[0018] In a further preferred embodiment, a limiting block is provided at the end portion of the first guide groove near the other end of the first partition plate. The limiting block is configured to restrict the sliding distance of the first guide block toward the other end of the first partition plate.

[0019] In another preferred embodiment, a second guide groove is provided on the side surface of the second partition plate facing the first partition plate, and a corresponding second guide block in sliding engagement with the second guide groove is provided on the side surface of one end of the first partition plate.

[0020] By adopting the above technical solutions, the present utility model achieves the following beneficial effects: The arcuate portion with an elastic structure provided on the first and / or second partition plate is configured to contact the side surface of the drawer, thereby improving contact reliability during use. Additionally, an EVA layer may be further provided on the arcuate portion. The lightweight and elastic characteristics of EVA material enhance the conformability and relative fixation between the device and the drawer sidewall, effectively preventing the partition device from shifting due to collisions during use. Moreover, the present solution ingeniously integrates subcomponents of the locking structure into the first and second partition plates. As a result, only the first and second partition plates need to be manufactured, and the locking structure can be assembled simultaneously by simply joining the two plates. Under this structural configuration, the device features a simple design with no loose or separate components, resulting in high assembly efficiency, ease of maintenance, and excellent operational reliability.BRIEF DESCRIPTION OF DRAWINGS

[0031] The present utility model is described in further detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are provided solely for illustrative purposes and are not intended to limit the scope of the utility model. Likewise, only some - not all - embodiments are disclosed herein; all other embodiments obtainable by those of ordinary skill in the art without creative effort fall within the protection scope of the utility model.

[0032] As shown in any of FIGS. 1-7, a retractable drawer dividing device according to this embodiment includes a first partition plate 1 and a second partition plate 2 slidably connected at one end. A locking structure 3 is disposed between the first partition plate 1 and the second partition plate 2. The locking structure 3 has a locked state and an unlocked state. In the locked state, the first partition plate 1 and the second partition plate 2 are constrained and fixed relative to each other; in the unlocked state, the first partition plate 1 and the second partition plate 2 are slidable relative to each other.

[0033] An arcuate portion 4 with an elastic structure is provided at the other end of each of the first partition plate 1 and the second partition plate 2, and the arcuate portion 4 is configured to contact a sidewall of the drawer. In alternative arrangements, the arcuate portion 4 may be provided at the other end of only one of the first partition plate 1 or the second partition plate 2.

[0034] The first partition plate 1 and the second partition plate 2 may be formed of an elastic plastic material, an elastic metal plate, or any other suitable resilient material.

[0035] In one structural example, a gap 41 is formed between the other end of the first and / or second partition plate 1, 2 and the arcuate portion 4. A spring tab 42 extends from the side of the arcuate portion 4 adjacent the gap 41 and in a direction away from the arcuate portion 4. When the arcuate portion 4 abuts the drawer sidewall, it undergoes deformation within the gap 41 under the applied force. The spring tab 42, functioning as a supporting elastic arm, contacts the end of the first or second partition plate 1, 2 when the deformation of the arcuate portion 4 exceeds a predetermined extent, thereby providing support and preventing excessive deformation, fracture, or other abnormal deformation of the arcuate portion 4.

[0036] Preferably, an EVA layer 43 is provided on the outer side of the arcuate portion 4. Owing to its lightweight and elastic characteristics, the EVA material enhances conformability and relative fixation between the device and the drawer sidewall, thereby preventing the partition device from shifting due to collisions after installation in the drawer.

[0037] To enhance guiding stability during relative sliding of the first partition plate 1 and the second partition plate 2 and to prevent lateral deviation, U-shaped first limiting portions 11 are provided on both sides of one end of the first partition plate 1. A limiting zone is defined between the pair of first limiting portions 11 to guide the first partition plate 1 and the second partition plate 2 to slide longitudinally relative to each other, with one end of the second partition plate 2 passing through the limiting zone.

[0038] Optionally, U-shaped second limiting portions 21 are provided on both sides of one end of the second partition plate 2. The pair of second limiting portions 21 respectively engage both sides of the first partition plate 1, thereby guiding the first partition plate 1 and the second partition plate 2 to slide longitudinally relative to each other.

[0039] Preferably, the main bodies of the first partition plate 1 and the second partition plate 2 are formed as concave shell structures. A rack structure 31 is provided along the inner wall of one side of the first partition plate 1 in the longitudinal direction. An elastic extension portion 32 is provided on one side of one end of the second partition plate 2 corresponding to the rack structure 31, the extension portion 32 being provided with locking teeth 33 that mesh with the rack structure 31. The locking teeth 33 and the rack structure 31 cooperatively constitute the locking structure 3. A clearance gap 35 is defined between the main body of the second partition plate 2 and the extension portion 32, and a pressing block 34 is provided on one side of the extension portion 32. Accordingly, the locking structure 3 includes the rack structure 31 disposed on the first partition plate 1, the extension portion 32 disposed on the second partition plate 2, the locking teeth 33, and the pressing block 34 connected to the extension portion 32, and the state of the locking structure 3 can be switched by actuating the pressing block 34.

[0040] Referring specifically to FIG. 5, when the locking structure 3 is in the locked state, the locking teeth 33 mesh with the rack structure 31, thereby constraining and fixing the first partition plate 1 and the second partition plate 2 relative to each other.

[0041] When the locking structure 3 is in the unlocked state, the pressing block 34 is actuated, causing the extension portion 32 to deform within the clearance gap 35 and disengage the locking teeth 33 from the rack structure 31, thus permitting the first partition plate 1 and the second partition plate 2 to slide relative to each other.

[0042] Referring in particular to FIG. 6 or FIG. 7, a first guide groove 12 is provided on the side surface of the first partition plate 1 facing the second partition plate 2. In the present embodiment, the first guide groove 12 comprises a pair of grooves, although a single groove may alternatively be used. A first guide block 23, slidably engaged with the first guide groove 12, is provided on the side surface of one end of the second partition plate 2.

[0043] As shown in FIG. 8, in an optional embodiment a limiting block 14 is provided at the end of the first guide groove 12 adjacent the other end of the first partition plate 1. The limiting block 14 restricts the sliding distance of the first guide block 23 toward the other end of the first partition plate 1.

[0044] For ease of assembly under the foregoing structural arrangement, first avoidance grooves 15 are provided on both sides of the other end of the first partition plate 1, corresponding to the second limiting portions 21 on the second partition plate 2, and second avoidance grooves 24 are provided on both sides of the other end of the second partition plate 2, corresponding to the first limiting portions 11 on the first partition plate 1. Referring to FIG. 9, the first and second partition plates 1, 2 are assembled by first bringing one end faces into contact so that the first limiting portions 11 align with the first avoidance grooves 15 and the second limiting portions 21 align with the second avoidance grooves 24. The end faces are then pressed together axially, the first partition plate 1 is held, and the pressing block 34 on the second partition plate 2 is depressed to disengage the locking teeth 33 of the locking structure 3 from the rack structure 31 on the first partition plate 1. The second partition plate 2 is then pulled away from the first partition plate 1, while the first limiting portions 11 sleeve over both sides of the second partition plate 2 and the second limiting portions 21 sleeve over both sides of the first partition plate 1.

[0045] As shown in FIG. 8, when a limiting block 14 is provided in the first guide groove 12, the side of the limiting block 14 facing away from the second partition plate 2 is formed as an inclined surface 141. The height of the limiting block 14 is slightly greater than the clearance between the first guide block 23 and the first partition plate 1. The first guide block 23 may be configured as a thin-plate structure, so that, during assembly, pulling the second partition plate 2 causes the first guide block 23 to elastically deform and pass over the limiting block 14, thereby completing assembly - an assembly technique commonly employed for plastic or elastic metal parts.

[0046] Alternatively, the first guide groove 12 may be formed without the limiting block 14. In that case, the relative position between the first partition plate 1 and the second partition plate 2 is governed directly by the cooperation of the locking structure 3 to achieve retractable adjustment of the partition device.

[0047] Referring to FIG. 6, in a further preferred embodiment, a second guide groove 22 may also be provided on the side surface of the second partition plate 2 facing the first partition plate 1, and a second guide block 13 slidably engaging the second guide groove 22 is provided on the side surface of one end of the first partition plate 1.

[0048] The foregoing description merely sets forth certain embodiments of the present utility model and does not limit its scope. All equivalent devices or process transformations derived from the specification and drawings, or applied directly or indirectly in other related technical fields, are deemed to fall within the scope of protection of the present utility model.

[0031] The present utility model is described in further detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are provided solely for illustrative purposes and are not intended to limit the scope of the utility model. Likewise, only some - not all - embodiments are disclosed herein; all other embodiments obtainable by those of ordinary skill in the art without creative effort fall within the protection scope of the utility model.

[0032] As shown in any of FIGS. 1-7, a retractable drawer dividing device according to this embodiment includes a first partition plate 1 and a second partition plate 2 slidably connected at one end. A locking structure 3 is disposed between the first partition plate 1 and the second partition plate 2. The locking structure 3 has a locked state and an unlocked state. In the locked state, the first partition plate 1 and the second partition plate 2 are constrained and fixed relative to each other; in the unlocked state, the first partition plate 1 and the second partition plate 2 are slidable relative to each other.

[0033] An arcuate portion 4 with an elastic structure is provided at the other end of each of the first partition plate 1 and the second partition plate 2, and the arcuate portion 4 is configured to contact a sidewall of the drawer. In alternative arrangements, the arcuate portion 4 may be provided at the other end of only one of the first partition plate 1 or the second partition plate 2.

[0034] The first partition plate 1 and the second partition plate 2 may be formed of an elastic plastic material, an elastic metal plate, or any other suitable resilient material.

[0035] In one structural example, a gap 41 is formed between the other end of the first and / or second partition plate 1, 2 and the arcuate portion 4. A spring tab 42 extends from the side of the arcuate portion 4 adjacent the gap 41 and in a direction away from the arcuate portion 4. When the arcuate portion 4 abuts the drawer sidewall, it undergoes deformation within the gap 41 under the applied force. The spring tab 42, functioning as a supporting elastic arm, contacts the end of the first or second partition plate 1, 2 when the deformation of the arcuate portion 4 exceeds a predetermined extent, thereby providing support and preventing excessive deformation, fracture, or other abnormal deformation of the arcuate portion 4.

[0036] Preferably, an EVA layer 43 is provided on the outer side of the arcuate portion 4. Owing to its lightweight and elastic characteristics, the EVA material enhances conformability and relative fixation between the device and the drawer sidewall, thereby preventing the partition device from shifting due to collisions after installation in the drawer.

[0037] To enhance guiding stability during relative sliding of the first partition plate 1 and the second partition plate 2 and to prevent lateral deviation, U-shaped first limiting portions 11 are provided on both sides of one end of the first partition plate 1. A limiting zone is defined between the pair of first limiting portions 11 to guide the first partition plate 1 and the second partition plate 2 to slide longitudinally relative to each other, with one end of the second partition plate 2 passing through the limiting zone.

[0038] Optionally, U-shaped second limiting portions 21 are provided on both sides of one end of the second partition plate 2. The pair of second limiting portions 21 respectively engage both sides of the first partition plate 1, thereby guiding the first partition plate 1 and the second partition plate 2 to slide longitudinally relative to each other.

[0039] Preferably, the main bodies of the first partition plate 1 and the second partition plate 2 are formed as concave shell structures. A rack structure 31 is provided along the inner wall of one side of the first partition plate 1 in the longitudinal direction. An elastic extension portion 32 is provided on one side of one end of the second partition plate 2 corresponding to the rack structure 31, the extension portion 32 being provided with locking teeth 33 that mesh with the rack structure 31. The locking teeth 33 and the rack structure 31 cooperatively constitute the locking structure 3. A clearance gap 35 is defined between the main body of the second partition plate 2 and the extension portion 32, and a pressing block 34 is provided on one side of the extension portion 32. Accordingly, the locking structure 3 includes the rack structure 31 disposed on the first partition plate 1, the extension portion 32 disposed on the second partition plate 2, the locking teeth 33, and the pressing block 34 connected to the extension portion 32, and the state of the locking structure 3 can be switched by actuating the pressing block 34.

[0040] Referring specifically to FIG. 5, when the locking structure 3 is in the locked state, the locking teeth 33 mesh with the rack structure 31, thereby constraining and fixing the first partition plate 1 and the second partition plate 2 relative to each other.

[0041] When the locking structure 3 is in the unlocked state, the pressing block 34 is actuated, causing the extension portion 32 to deform within the clearance gap 35 and disengage the locking teeth 33 from the rack structure 31, thus permitting the first partition plate 1 and the second partition plate 2 to slide relative to each other.

[0042] Referring in particular to FIG. 6 or FIG. 7, a first guide groove 12 is provided on the side surface of the first partition plate 1 facing the second partition plate 2. In the present embodiment, the first guide groove 12 comprises a pair of grooves, although a single groove may alternatively be used. A first guide block 23, slidably engaged with the first guide groove 12, is provided on the side surface of one end of the second partition plate 2.

[0043] As shown in FIG. 8, in an optional embodiment a limiting block 14 is provided at the end of the first guide groove 12 adjacent the other end of the first partition plate 1. The limiting block 14 restricts the sliding distance of the first guide block 23 toward the other end of the first partition plate 1.

[0044] For ease of assembly under the foregoing structural arrangement, first avoidance grooves 15 are provided on both sides of the other end of the first partition plate 1, corresponding to the second limiting portions 21 on the second partition plate 2, and second avoidance grooves 24 are provided on both sides of the other end of the second partition plate 2, corresponding to the first limiting portions 11 on the first partition plate 1. Referring to FIG. 9, the first and second partition plates 1, 2 are assembled by first bringing one end faces into contact so that the first limiting portions 11 align with the first avoidance grooves 15 and the second limiting portions 21 align with the second avoidance grooves 24. The end faces are then pressed together axially, the first partition plate 1 is held, and the pressing block 34 on the second partition plate 2 is depressed to disengage the locking teeth 33 of the locking structure 3 from the rack structure 31 on the first partition plate 1. The second partition plate 2 is then pulled away from the first partition plate 1, while the first limiting portions 11 sleeve over both sides of the second partition plate 2 and the second limiting portions 21 sleeve over both sides of the first partition plate 1.

[0045] As shown in FIG. 8, when a limiting block 14 is provided in the first guide groove 12, the side of the limiting block 14 facing away from the second partition plate 2 is formed as an inclined surface 141. The height of the limiting block 14 is slightly greater than the clearance between the first guide block 23 and the first partition plate 1. The first guide block 23 may be configured as a thin-plate structure, so that, during assembly, pulling the second partition plate 2 causes the first guide block 23 to elastically deform and pass over the limiting block 14, thereby completing assembly - an assembly technique commonly employed for plastic or elastic metal parts.

[0046] Alternatively, the first guide groove 12 may be formed without the limiting block 14. In that case, the relative position between the first partition plate 1 and the second partition plate 2 is governed directly by the cooperation of the locking structure 3 to achieve retractable adjustment of the partition device.

[0047] Referring to FIG. 6, in a further preferred embodiment, a second guide groove 22 may also be provided on the side surface of the second partition plate 2 facing the first partition plate 1, and a second guide block 13 slidably engaging the second guide groove 22 is provided on the side surface of one end of the first partition plate 1.

[0048] The foregoing description merely sets forth certain embodiments of the present utility model and does not limit its scope. All equivalent devices or process transformations derived from the specification and drawings, or applied directly or indirectly in other related technical fields, are deemed to fall within the scope of protection of the present utility model.
