Description

Technical Field

[0001] This application relates to the field of storage cabinet technology, and more specifically, to a drawer, cabinet unit, and modular combination cabinet. Background Technology

[0002] Cabinets, as storage units, are a common type of furniture, and almost every household has them in their rooms. Cabinets can be divided into drawer cabinets and open cabinets. Open cabinets, as the name suggests, are cabinets or shelves without doors, partitions, or curtains. Their storage space is completely open and easily visible, offering convenient access and strong display appeal, making them generally used for storing display items. In contrast to open cabinets, drawer cabinets feature pull-out drawers installed within multiple shelves. Items are stored inside the drawers, which are then pulled out to access them. Drawer cabinets offer better concealment and a neater, more aesthetically pleasing appearance, making them suitable for storing small items or private items.

[0003] Most drawer designs currently use screws to secure the front panel, bottom panel, side panels, and back panel together. This design requires numerous connectors and specialized tools for installation, making it difficult for users. Improper installation can easily damage the materials, and once the screws are in place, disassembly is difficult. Therefore, proper installation procedures must be followed.

[0004] Therefore, in relevant existing technologies, such as the storage box and furniture disclosed in patent application CN209733104U, the front panel of the drawer structure is fastened to the two side panels using gourd-shaped holes and connecting shafts, and the two ends of the side panels are fitted with locking protrusions that engage with the connecting holes. However, the above structure still has the following drawbacks: before installation, a body part with gourd-shaped locking holes needs to be embedded in the front panel, and corresponding locking protrusion structures need to be connected to the front ends of the two side panels, resulting in a significant increase in connecting parts, cumbersome installation steps, and difficulty in disassembling the back panel after it has been fitted with the two side panels. Summary of the Invention

[0005] The technical problem to be solved by this application is to overcome at least one of the defects of the above-mentioned related technologies and to provide a drawer that users can quickly disassemble and assemble themselves without the need for any tools.

[0006] The technical solution of this application is to provide a drawer including a front panel, a rear panel, a bottom panel, and left and right side panels. The front ends of the left and right side panels are slidably mounted on the front panel. The rear ends of the left and right side panels are provided with first positioning blocks. The two ends of the rear panel are provided with first positioning holes for the first positioning blocks to pass through and engage. The end of the first positioning block that protrudes from the rear panel is detachably fitted with a positioning lock block.

[0012] In some embodiments, the second positioning block is disposed through the second positioning hole, and the end of the second positioning block protruding from the rear plate is detachably fitted with a positioning lock block.

[0013] In some embodiments, the positioning strip and the front plate are an integral structure, the left and right side plates and the corresponding first positioning blocks are an integral structure, and the second positioning blocks and the reinforcing rod are an integral structure.

[0014] In some embodiments, each of the positioning locking blocks is provided with a dovetail-shaped groove, and the outer ends of the first positioning block and the second positioning block are provided with dovetail-shaped protrusions that are adapted to the dovetail grooves, and the front end of each of the positioning locking blocks abuts and limits the movement of the rear plate.

[0015] In summary, the drawer proposed in this application has the following advantages compared with related technologies: The drawer's components are detachably connected without the need for fasteners or tools, allowing for quick and easy assembly and disassembly by the user. Furthermore, a reinforcing bar is installed under the bottom plate to ensure its load-bearing capacity. The front end of the reinforcing bar mates with the front plate, and the rear end is inserted into the rear plate for positioning, further enhancing the structural stability between the front and rear plates. Moreover, apart from the positioning lock block being made of a separate material, the front plate, rear plate, bottom plate, left and right side plates, and reinforcing bar are all made of sheet metal and integrally molded with their respective insert components, significantly reducing the number of loose connecting parts. This not only facilitates installation but also lowers production costs.

[0016] Another technical solution of this application is to provide a cabinet unit, including a cabinet frame that is detachably assembled from a bottom cabinet panel, left and right cabinet panels and a rear cabinet panel. The top of the cabinet frame is detachably connected to a support strip, and the support strip has multiple insertion holes. The lower end surface of the bottom cabinet panel has multiple protruding insertion posts for inserting and cooperating with each of the insertion holes. Drawers of any of the above structures are slidably installed in the cabinet frame.

[0017] In some embodiments, mounting components are connected to the inner walls of the left and right cabinet panels, and each mounting component has a gourd hole. Connecting shafts are embedded at both ends of the bottom cabinet panel, the rear cabinet panel, and the support strip. Each connecting shaft has a limiting boss at its outer end for engaging with the gourd hole.

[0018] In summary, the cabinet unit proposed in this application has the following advantages compared with related technologies: The cabinet unit of this application has a detachable structure, and the bottom cabinet plate, rear cabinet plate and left and right cabinet plates that make up the cabinet unit are all connected by connecting shafts with limiting bosses and mounting parts with hoist holes, which can be assembled by the user. In addition, each cabinet unit is provided with a plug hole on the top and a corresponding plug post on the bottom. The user can select the appropriate number of cabinet units to stack and combine together according to actual needs.

[0019] Another technical solution of this application is to provide a modular combination cabinet, including at least one cabinet unit and a cover plate, wherein a plurality of plug-in posts are protruding outward on the lower end surface of the cover plate. When there is one cabinet unit, the cover plate is inserted into the top of the cabinet unit through multiple plug-in posts; When there are two or more cabinet units, the cabinet units are stacked vertically, and the bottom plate of the upper cabinet unit is fitted to the top of the cabinet unit below it through multiple plug-in pins, and the cover plate is fitted to the top of the uppermost cabinet unit through multiple plug-in pins.

[0020] In some embodiments, the system further includes an open cabinet unit and an open cabinet top plate, and the open cabinet bottom plate has the same structure as the cover plate. The bottom of the open cabinet unit and the open cabinet top plate are provided with multiple plug-in posts, and the top of the open cabinet unit is provided with multiple plug-in holes that match the plug-in posts. The open cabinet unit can be vertically assembled with the cabinet unit or arranged side by side on one side of the cabinet unit.

[0021] In summary, compared with related technologies, the modular combination cabinet proposed in this application has the following advantages: In the modular combination cabinet structure of this application, users can select and assemble corresponding cabinet units according to their actual needs.

That is, users can freely combine and use modular cabinet units with corresponding functions according to their actual needs, and assembly can be quickly and easily done by simply inserting and connecting the plugs and holes. Moreover, the panels of each modular cabinet unit are detachably connected by corresponding snap-fit ​​structures, meaning that each panel can be packaged separately during packaging and transportation, making transportation convenient.

[0022] Other improvements and advantages of this application will be set forth in the following detailed description and will be apparent in part from the specification or may be learned by practicing the application.

[0025] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In the embodiments of this application, unless otherwise explicitly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be in direct contact with the first feature, or indirect contact with the first feature through an intermediate medium. Moreover, the first feature "below" or "below" the second feature may mean that the first feature is directly below or diagonally below the second feature, or simply that the horizontal height of the first feature is less than that of the second feature.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 7This application discloses a drawer, the structure of which includes a front panel 1, a rear panel 2, a bottom panel 3, and left and right side panels 4. The front ends of the left and right side panels 4 are vertically slidably mounted on the rear side wall of the front panel 1. Each of the rear ends of the left and right side panels 4 is provided with a first positioning block 5. The rear panel 2 has first positioning holes 6 at both ends for the first positioning blocks 5 on the left and right side panels 4 to pass through and engage. A positioning lock block 7 is detachably mounted on one end of the first positioning block 5 that protrudes from the rear panel 2. The positioning lock block 7 is mainly used to lock the left and right side panels. The side panel 4 and the back panel 2 are locked together to prevent the back panel 2 from separating from the side panel 4. In addition, the two sides of the bottom panel 3 are slidably assembled between the left and right side panels 4 in the direction from back to front, and the front end of the bottom panel 3 is limited to the front panel 1 so that it cannot move relative to the front panel in the vertical direction, thereby ensuring the vertical position limitation of the bottom panel 3 and the front panel 1. Furthermore, since the bottom panel 3 is connected to the left and right side panels 4, and the left and right side panels 4 are connected to the back panel 2 by insertion, the stability of the entire drawer structure after assembly is ensured.

[0030] Specifically, in the above structure, the inner walls of the front ends of the left and right side plates 4 are each provided with a first positioning groove 8 extending vertically. Positioning strips 9 protrude outwards from both ends of the rear side wall of the front plate 1, and each positioning strip 9 has a positioning protrusion 10 for slidingly engaging with the two first positioning grooves 8. During installation, the front ends of the left and right side plates 4 are pressed against the rear side wall of the front plate 1, and then slid vertically relative to each other until the positioning protrusions 10 on both sides of the front plate 1 are fitted together with the first positioning grooves 8 at the front ends of the left and right side plates 4. Preferably, the positioning groove is a dovetail groove, a T-groove, or a semi-circular groove.

[0031] In this embodiment, the base plate 3 is slidably fitted between the left and right side plates 4. Specifically, a second positioning groove 11 extending in the front-rear direction is provided on the inner wall of the lower end of each of the left and right side plates 4. That is, when the front ends of the left and right side plates 4 are connected to the front plate 1, the two sides of the base plate 3 slide and fit into the two second positioning grooves 11 from back to front. In addition, a first positioning slot 12 is provided on the inner wall of the lower end of the front plate 1, and the first positioning slot 12 is located below the positioning strip 9. The front end of the base plate 3 is inserted and positioned in the first positioning slot 12 to achieve a limiting fit between the base plate 3 and the front plate 1. In this structure, in order to simplify the manufacturing process, the width of the two second positioning grooves 11 and the first positioning slot 12 is directly set to match the thickness of the base plate 3. That is, the outer periphery of the base plate 3 does not need to undergo any processing to achieve connection and fit with the left and right side plates 4 and the front plate 1.

[0032] To further ensure the structural stability of the base plate 3 after connection, a second positioning slot 13 is provided on the inner wall of the lower end of the rear plate 2 in the above structure, and the rear end of the base plate 3 is inserted and positioned in the second positioning slot 13. Similarly, the width of the second positioning slot 13 here is adapted to the thickness of the base plate 3.

[0033] Furthermore, in this embodiment, a reinforcing rod 14 for supporting the base plate 3 is also provided between the front plate 1 and the rear plate 2. The reinforcing rod 14 is detachably connected to both the front plate 1 and the rear plate 2. Specifically, a rectangular support boss 15 protrudes outward on the rear sidewall of the front plate 1, and the upper end of the support boss 15 has a recessed receiving groove 16. The front end of the reinforcing rod 14 is fitted into the receiving groove 16, and the rear end of the reinforcing rod 14 has a second positioning insert 17. The rear plate 2 has a second positioning hole 18 for the second positioning insert 17 to be inserted into. The second positioning hole 18 can be a through hole or a blind hole. If the second positioning hole 18 adopts the same through hole as the first positioning hole 6, then a positioning locking block 7 also needs to be set at the end of the reinforcing rod 14 that protrudes from the rear plate 2 to achieve locking and limiting in the front and rear directions. At the same time, a positioning pin is provided vertically on the bottom wall of the receiving groove 16, and a positioning pin hole is provided at one end of the reinforcing rod 14. Therefore, when one end of the reinforcing rod 14 is fitted in the receiving groove 16, the positioning pin is inserted and fitted in the positioning pin hole, which effectively enhances the stability between the front plate 1 and the rear plate 2 and ensures that the front plate 1 and the rear plate 2 are not easily separated in the front and rear directions.

[0034] In this embodiment, preferably, the positioning strip 9 and the front plate 1 are an integral structure, the left and right side plates 4 and the corresponding first positioning blocks 5 are an integral structure, and the second positioning block 17 and the reinforcing rod 14 are an integral structure. The integral structure not only facilitates processing but also effectively simplifies the assembly structure. Of course, in some other embodiments, if the above factors are not considered, the positioning strip 9, the first positioning block 5, and the second positioning block 17 can also be independent accessories, which can be connected to the front plate 1, the left and right side plates 4, and the reinforcing rod 14 later.

[0035] More specifically, in the above structure, each positioning locking block 7 has a recessed dovetail-shaped groove 19, and the outer ends of the first positioning insert 5 and the second positioning insert 17 are provided with dovetail-shaped protrusions 20 that are adapted to the dovetail grooves. Furthermore, the front end of each positioning locking block 7 abuts against and limits the movement of the rear plate 2. Preferably, the positioning locking block 7 is an elastic element or a plastic element, so that it can adaptably deform elastically when inserted with the corresponding positioning insert, facilitating the locking and engagement of the dovetail-shaped protrusion 20 with the corresponding dovetail-shaped groove 19.

[0036] In some other embodiments, the positioning lock block 7 can also be divided into two parts along its length. Each segment of the positioning lock block 7 has an open dovetail groove 19 at one end and a closed end at the other end. In this case, it can be slidably assembled onto the dovetail protrusion 20 at the end of the corresponding positioning insert along the open end. After the two segments of the positioning lock block 7 are installed, they are combined into a complete positioning lock block 7 structure, which still looks like an integral structure.

[0037] The drawer installation steps in the above embodiment are as follows: First, slide the front ends of the left and right side panels 4 vertically together with the front panel 1; then, install the front end of the reinforcing rod 14 into the receiving groove 16 on the front panel 1; next, install the bottom plate 3, and slide the two sides of the bottom plate 3 into the second positioning groove 11 of the left and right side panels 4 until the front end of the bottom plate 3 is inserted into the first positioning slot 12 of the front panel 1; then, install the rear plate 2 from back to front, so that the positioning blocks corresponding to the rear ends of the left and right side panels 4 and the reinforcing rod 14 are inserted into the corresponding positioning holes on the rear plate 2, and push the rear plate 2 forward until the rear end of the bottom plate 3 is inserted into the second positioning slot 13 of the rear plate 2; finally, install the positioning lock block 7. In this way, the entire drawer is assembled. The entire assembly process does not require any fasteners or auxiliary tools, and users can easily complete it; and if you need to move or store it later, you can also easily disassemble it. When disassembling, first remove the corresponding positioning lock block 7, and then you can disassemble the rear plate 2, bottom plate 3, left and right side panels 4 and reinforcing rod 14 one by one, which is very convenient.

[0038] In some other embodiments, the two sides of the base plate 3 can also be inserted between the left and right side plates 4 through the structure of positioning pins and positioning grooves. If other positioning structures (such as pins) are provided between the left and right side plates 4 and the front plate 1, the base plate 3 can be directly contacted without the setting of a limiting structure.

[0039] See appendix Figures 8 to 13 Another embodiment of this application discloses a cabinet unit, which includes a cabinet frame detachably assembled from a base cabinet panel 21, left and right cabinet panels 22, and a rear cabinet panel 23. A support strip 24 is detachably connected to the top of the cabinet frame, and the support strip 24 has multiple insertion holes 25. Multiple insertion posts 26 protrude outwards from the lower end face of the base cabinet panel 21 for respectively engaging with the insertion holes 25. The aforementioned drawers are slidably mounted inside the cabinet frame. Preferably, four rectangular insertion posts 26 are provided on the lower end face of the base cabinet panel 21, and two support strips 24 are provided at the top of the cabinet frame. Each support strip 24 has two insertion holes 25, and the positions of the four insertion holes 25 on the two support strips 24 correspond to the four insertion posts 26 on the base cabinet panel 21. In this structure, in order to further ensure the stability of the connection structure of the two support bars 24, reinforcing protrusions 34 are provided on the inner walls of the upper ends of the left and right cabinet panels 22, and the two ends of the support bars 24 are respectively supported and abutted against the upper ends of the reinforcing protrusions 34.

[0040] Specifically, in the above structure, mounting parts 27 are connected to the inner walls of the left and right cabinet panels 22. Each mounting part 27 has a gourd-shaped hole 28. Connecting shafts 29 are embedded at both ends of the bottom cabinet panel 21, the rear cabinet panel 23, and the support strip 24. Each connecting shaft 29 has a limiting boss 30 at its outer end for engaging with the gourd-shaped hole 28. In this structure, when the mounting parts 27 are directly fixed to the inner walls of the left and right cabinet panels 22 with screws, a certain space needs to be left between the gourd-shaped hole 28 on the mounting part 27 and the inner wall of the left and right cabinet panels 22 to facilitate engagement.

[0041] In this embodiment, as a preferred structural form, multiple mounting slots are provided on the inner walls of the left and right cabinet panels 22, and each mounting component 27 is embedded in the corresponding mounting slot. Here, the multiple mounting components 27 are connected and fitted into the corresponding mounting slots by screws. Each mounting component 27 is provided with a gourd hole 28. Connecting shafts 29 are embedded at both ends of the bottom cabinet panel 21, the rear cabinet panel 23, and the support bar 24. The outer end of each connecting shaft 29 is provided with a limiting boss 30 for engaging with the gourd hole 28. In the above structure, a clearance portion is also required in the mounting slot corresponding to each gourd hole 28 to facilitate the movement of the limiting boss 30 during engagement. During installation, the two ends of the bottom cabinet panel 21, the rear cabinet panel 23, and the support bar 24 are engaged with the gourd holes 28 on the left and right cabinet panels 22 through the connecting shafts 29. In this preferred embodiment, the gourd hole 28 for connecting the base cabinet plate 21 and the support bar 24 is arranged horizontally, and the gourd hole 28 for connecting the rear cabinet plate 23 is arranged vertically, with the larger hole located at the top; and the limiting boss 30 is a cylindrical structure, with its diameter being larger than the diameter of the small hole of the gourd hole 28 and smaller than the diameter of the large hole of the gourd hole 28. That is, during installation, the limiting boss 30 at the end of the connecting shaft 29 is first inserted into the large hole of the gourd hole 28, and then the connecting shaft 29 is moved until the limiting boss 30 corresponds to the small hole of the gourd hole 28, thus completing the quick installation of the connecting shaft 29 and the mounting part 27.

[0042] In the above structure, the connecting parts that are fitted with the gourd hole 28 can be bolts. The bolt head is the limiting boss 30, and the screw is the connecting shaft 29. Standard parts are directly selected as connecting parts, which further reduces costs.

[0043] See Figures 14-19 Another embodiment of this application discloses a modular combination cabinet, which includes at least one of the aforementioned cabinet units and a cover plate 31. Four plug-in posts 26 are provided on the lower end surface of the cover plate 31. The plug-in posts 26 here are the same in position and shape as the four plug-in posts 26 on the bottom cabinet plate 21.

[0044] When there is only one cabinet unit, the cover plate 31 is directly inserted into the top of the cabinet unit via multiple plug-in posts 26 to form a complete single-layer cabinet. See Appendix. Figure 8 The structure shown.

[0045] When there are two or more cabinet units, they are stacked vertically. The bottom plate 3 of the upper cabinet unit is fitted into the top of the cabinet unit below it via multiple insertion posts 26. The cover plate 31 is then fitted into the top of the uppermost cabinet unit via multiple insertion posts 26, forming a multi-layered cabinet. (See Appendix) Figure 14 The structure shown.

[0046] In this embodiment, see Appendix Figure 17 ~Attached Figure 19 Furthermore, the cabinet unit can be modularly combined with other types of cabinet units. That is, the modular combination cabinet also includes open cabinet unit 32 and open cabinet top plate 33. The bottom of both open cabinet unit 32 and open cabinet top plate 33 is provided with multiple plug-in posts 26. The number and position of the plug-in posts 26 here are the same as those of the plug-in posts 26 at the bottom of the bottom cabinet plate 21. Correspondingly, the top of open cabinet unit 32 is also provided with multiple plug-in holes 25 that match the plug-in posts 26. The open cabinet unit 32 can be vertically assembled with the cabinet unit or arranged side by side on one side of the cabinet unit.

[0047] More specifically, open cabinet units 32 can be combined on the aforementioned single-layer or multi-layer cabinets. Specifically, during assembly, the top cover 31 of the corresponding cabinet needs to be removed, and the four insertion posts 26 at the bottom of the open cabinet unit 32 are inserted into the four insertion holes 25 at the top of the uppermost cabinet unit. Finally, the open cabinet top plate 33 is installed on top of the open cabinet unit 32. Preferably, in this structure, the open cabinet top plate 33 and the cover 31 have the same structure and can be interchanged.

[0048] In addition, the open cabinet unit 32 can be used side by side with the cabinet unit. That is, users can assemble several cabinet units vertically together as needed, and install a cover plate 31 on the top of the uppermost cabinet unit to form a drawer cabinet; or assemble several open cabinet units 32 vertically together, and install an open cabinet top plate 33 or cover plate 31 on the top to form an open cabinet, which can be placed side by side on one side of the drawer cabinet for combined use; or two drawer cabinets and one open cabinet can be assembled, and the open cabinet can be placed between the two drawer cabinets for combined use. Of course, users can also perform other combinations and assemblies as needed, not limited to the above structural forms, which will not be elaborated here.

[0049] In the above structure, the open cabinet structure is similar to the cabinet unit structure. Both are detachable and assembled using corresponding bottom cabinet panels 21, left and right cabinet panels 22, and rear cabinet panels 23. The assembly method is also the same, using corresponding connecting shafts 29 and mounting parts 27 with gourd holes 28 for assembly. Further details will not be provided here. As for the open cabinet unit 32, it can be a single-layer structure or a multi-layer structure. When it is a multi-layer structure, the corresponding left and right cabinet panels 22 and rear cabinet panels 23 can be an integral structure to simplify the assembly process.
