Description

Technical Field

[0001] The utility model relates to the technical field of combined cabinets, in particular to a quick-assembly and disassembly combined cabinet. Background Technique

[0002] As a modular storage furniture, a combined cabinet usually consists of core components such as a cabinet body, partitions, and drawers. Traditional combined cabinets adopt the factory pre-assembly mode, and the components are assembled through permanent fixed connection methods such as tenon-mortise, gluing, or welding. Although such a structure can ensure overall stability, it has significant defects: large volume and inability to be disassembled, resulting in low utilization rate of logistics space, significantly increasing transportation costs and warehouse floor area. Even during multiple handling processes, the overall cabinet body is prone to corner damage or loosening of the connection structure due to collision, directly affecting the service life of the product.

[0003] Therefore, currently, there are detachable and installable combined cabinets, which adopt screw connections. Although this method realizes the separate transportation of components, there are the following technical bottlenecks: the screw holes of the plates are prone to wear and expansion during repeated disassembly and assembly, resulting in loose connections or even failures. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide a quick-assembly and disassembly combined cabinet with high connection stability, high disassembly and assembly convenience, and strong structural durability.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A quick-assembly and disassembly combined cabinet includes a back panel, side panels on both sides, a top panel above, two partitions below the top panel, and two drawers. The two partitions are arranged at intervals, and a drawer cavity is formed below the lowermost partition. The drawer is in a sliding fit with the drawer cavity.

[0007] Four auxiliary holes penetrating the plate surface are provided at the front and rear of the side panel. An auxiliary block is provided in the auxiliary hole. The auxiliary block is in a "field" shape. Two threaded holes are provided on each side of the auxiliary block.让位孔 are provided on the front side, rear side, and upper side of the side panel corresponding to the threaded holes. The back panel and the top panel are provided with through holes penetrating corresponding to the让位孔.

[0008] The back panel connecting bolt passes through the through hole of the back panel, the让位孔 of the side panel and is connected to the threaded hole of the auxiliary block; the top panel connecting bolt passes through the through hole of the top panel, the让位孔 of the side panel and is connected to the threaded hole of the auxiliary block.

[0009] Upper right-angle brackets are fixedly installed on the auxiliary blocks in the second position in the vertical direction, and lower right-angle brackets are fixedly installed on the auxiliary blocks in the third position in the vertical direction. The upper right-angle brackets and the lower right-angle brackets are respectively used to support the two partitions.

[0010] In this way, the combined cabinet consists of a back panel, side panels located on both sides of the back panel, and a top panel located above the back panel and the side panels to form a basic framework. Inside the basic framework, two spaced-apart partitions and two drawers are installed. The drawers are located below the partitions, and the drawers are in sliding fit with the drawer cavities.

[0011] To address the problem that direct screw connection currently has, namely, during repeated disassembly and assembly, it is easy to cause wear and expansion of the threaded holes in the plates, resulting in loose connections or even failures, auxiliary blocks are added. Multiple-direction threaded holes are integrated in the "cross-shaped" auxiliary blocks. When connecting, it does not directly connect to the back panel, side panels, or top panel, but to the auxiliary blocks. When the threaded holes on the auxiliary blocks are enlarged, the auxiliary blocks can be directly replaced, without the need to directly scrap the entire combined cabinet.

[0012] Four auxiliary holes penetrating the plate surfaces are provided at both the front and rear of the side panels. The auxiliary blocks are placed in the auxiliary holes, and through holes corresponding to the让位 holes are provided in the back panel and the top panel for convenient connection. During specific connection, the back panel connection bolts pass through the through holes in the back panel, the让位 holes in the side panels from the direction of the back panel and are connected to the threaded holes of the auxiliary blocks. All four auxiliary blocks are connected to the back panel through the back panel connection screws, making the connection between the side panel and the back panel more reliable and stable. The top panel connection bolts pass through the through holes in the top panel, the让位 holes in the side panels from the direction of the top panel and are connected to the threaded holes of the auxiliary blocks, connecting the top panel to the two auxiliary blocks at the upper ends of the two side panels. Specifically, the back panel connection bolts and the top panel connection bolts only connect to the threaded holes of the auxiliary blocks and do not directly extend into the interior of the auxiliary blocks. Therefore, the back panel connection bolts and the top panel connection bolts will not collide and interfere within the auxiliary blocks.

[0013] After the connection of the back panel, side panels, and top panel is completed, the upper partition is placed on the upper right-angle bracket, and the lower partition is placed on the lower right-angle bracket. The upper partition and the lower partition are made of wood and have their own gravity, which can press on the upper right-angle bracket or the lower right-angle bracket by their own gravity, and the installation is stable and reliable.

[0014] Through the setting of the auxiliary blocks, it avoids the problem of wear of the threaded holes caused by traditional screws directly screwing into the plates, has high connection stability, high disassembly and assembly convenience, and strong structural durability.

[0015] Preferably, the auxiliary blocks located at the front of the side panels are connected to the side panels through auxiliary connection bolts.

[0016] Preferably, both the upper right-angle bracket and the lower right-angle bracket are fixedly installed with pins, and the partitions are provided with insertion holes that are in insertion fit with the pins.

[0017] Preferably, both sides of the drawer are fixedly equipped with inner rails, and the inner ends of the inner rails are rotatably equipped with rollers; the two side panels are provided with outer rails corresponding to the inner rails, the rollers are in rolling cooperation with the outer rails, the outer ends of the outer rails are provided with blocks protruding upwards, and the outer side of the drawer is recessed to form a handle.

[0018] Preferably, it also includes a baffle, which is located below the drawer cavity, and the two ends of the baffle are provided with corresponding side plates and have light holes through which auxiliary connecting bolts can pass.

[0019] Preferably, the back plate, the front side of the side plate, the top plate and the baffle are respectively provided with relief grooves corresponding to the auxiliary block, and the relief grooves are provided with gaskets, and the gaskets are provided with through holes.

[0020] Preferably, the upper auxiliary block is fixedly equipped with a top right-angle bracket, the upper side of which is in contact with the top plate; the lower auxiliary block is fixedly equipped with a bottom right-angle bracket, the side of which is close to the back plate is in contact with the back plate, and the side of which is close to the baffle is in contact with the baffle.

[0021] In summary, this quick-assembly and disassembly cabinet has the advantages of high connection stability, convenient assembly and disassembly, and strong structural durability. Attached Figure Description

[0029] The present utility model will be further described in detail below in conjunction with the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0030] As Figure 1-7 shown, a quick-assembly and disassembly combined cabinet includes a back panel 1, side panels 2 on both sides, a top panel 3 above, two partition boards 4 below the top panel, and two drawers 5. The two partition boards are arranged at intervals. Below the lowermost partition board is a drawer cavity, and the drawer is in sliding fit with the drawer cavity.

[0031] Four auxiliary holes 6 penetrating the plate surface are provided on both the front and rear parts of the side panel. An auxiliary block 7 is provided in the auxiliary hole. The auxiliary block is in the shape of a "field". Two threaded holes 8 are provided on each side of the auxiliary block.让位孔9 are provided on the front side, rear side, and upper side of the side panel corresponding to the threaded holes; through holes 10 are provided on the back panel and the top panel corresponding to the让位孔9.

[0032] The back panel connecting bolt 11 passes through the through hole of the back panel, the让位孔9 of the side panel, and is connected to the threaded hole of the auxiliary block; the top panel connecting bolt 12 passes through the through hole of the top panel, the让位孔9 of the side panel, and is connected to the threaded hole of the auxiliary block.

[0033] Upper right-angle brackets 13 are fixedly installed on the auxiliary blocks in the second position along the vertical direction, and lower right-angle brackets 14 are fixedly installed on the auxiliary blocks in the third position along the vertical direction. The upper right-angle brackets and the lower right-angle brackets are respectively used to support the two partition boards.

[0034] In this way, the combined cabinet is composed of a back panel, side panels on both sides of the back panel, and a top panel above the back panel and the side panels to form a basic framework. Two partition boards arranged at intervals and two drawers are installed in the basic framework. The drawers are located below the partition boards, and the drawers are in sliding fit with the drawer cavity.

[0035] Aiming at the problem that directly connecting with screws in the current situation is likely to cause wear and expansion of the threaded holes of the plates during repeated disassembly and assembly, resulting in loosening or even failure of the connection, an auxiliary block is added. Multi-directional threaded holes are integrated in the "field"-shaped auxiliary block. When connecting, it is not directly connected to the back panel, side panel, and top panel, but is connected to the auxiliary block. When the threaded holes on the auxiliary block are enlarged, the auxiliary block can be directly replaced without directly scrapping the entire combined cabinet.

[0036] Four auxiliary holes are provided at the front and rear of the side plates, penetrating the plate surface. Auxiliary blocks are placed within these holes. Corresponding clearance holes on the back plate and top plate also have through holes for easy connection. During connection, the back plate connecting bolts are passed through the through holes on the back plate and the clearance holes on the side plates, connecting to the threaded holes of the auxiliary blocks. All four auxiliary blocks are connected to the back plate using back plate connecting screws, ensuring a more reliable and stable connection between the side plates and the back plate. Similarly, the top plate connecting bolts are passed through the through holes on the top plate and the clearance holes on the side plates, connecting to the threaded holes of the auxiliary blocks. The top plate is then connected to the two auxiliary blocks at the top of the two side plates. Specifically, the back plate connecting bolts and top plate connecting bolts only connect to the threaded holes of the auxiliary blocks and do not extend directly into the auxiliary blocks, thus preventing collisions and interference within the auxiliary blocks.

[0037] After the back panel, side panels, and top panel are connected, place the upper partition on the upper right-angle frame and the lower partition on the lower right-angle frame. The upper and lower partitions are made of wood and have their own weight, so they can be pressed against the upper or lower right-angle frame by their own weight, making the installation stable and reliable.

[0038] By using auxiliary blocks, the problem of thread hole wear caused by traditional screws directly entering the plate is avoided, resulting in high connection stability, easy assembly and disassembly, and strong structural durability.

[0039] In practice, the auxiliary block located at the front of the side plate is connected to the side plate via auxiliary connecting bolts 15. The auxiliary connecting bolts ensure that the auxiliary block, which is not connected to the back plate, can be fixedly connected to the side plate, preventing the auxiliary block from detaching from the side plate.

[0040] In implementation, both the upper and lower right-angle frames are fixedly equipped with pins 16, and the partition is provided with insertion holes 17 that engage with the pins. During partition installation, the pins engage with the insertion holes and are inserted into them, making the partition installation more reliable and stable, limiting the horizontal displacement of the partition, and improving the installation reliability of the partition.

[0041] In implementation, inner rails 18 are fixedly installed on both sides of the drawer, and rollers 19 are rotatably installed on the inner ends of the inner rails. Outer rails 20 are provided on the two side panels corresponding to the inner rails. The rollers roll in cooperation with the outer rails, and a stop 21 protrudes upward from the outer end of the outer rail. A handle 22 is formed by the inward indentation on the outer side of the drawer. Both the inner and outer rails are existing drawer installation structures. During installation, one end of the drawer is inserted above the two outer rails, the rollers roll in cooperation with the outer rails, and the stop supports one end of the inner rail, keeping the drawer level. Simultaneously, the stop acts as a physical anti-slip mechanism, preventing the drawer from slipping out of its original position.

[0042] In practice, the side panel with the handle is higher than the other panels. This design allows the side panel with the handle to block one side of the drawer cavity when one end is inserted into the drawer cavity and engages with the external rails. The recessed outer side of the drawer forms the handle, which also facilitates pulling the drawer out.

[0043] In implementation, a baffle 23 is also included. The baffle is located below the drawer cavity, and its two ends are corresponding to the side panels and have through-holes 24 that allow auxiliary connecting bolts to pass through. The baffle blocks the bottom of the drawer cavity, reducing dust ingress. The through-holes also facilitate the connection of the auxiliary connecting bolts to the side panels, allowing for simultaneous fixing of the baffle and side panels while the auxiliary block is being secured.

[0044] In implementation, the front side of the back plate, side plate, top plate, and baffle are respectively provided with relief grooves 25 corresponding to the auxiliary blocks. Gaskets 26 are provided in the relief grooves, and through holes 27 are provided on the gaskets. The relief grooves, with gaskets placed within them, cause the surfaces of the back plate, top plate, side plate, and baffle to be crushed. The gaskets disperse the locking pressure.

[0045] In implementation, a top right-angle bracket 28 is fixedly installed on the upper auxiliary block, with its upper side fitting against the top plate; a bottom right-angle bracket 29 is fixedly installed on the lower auxiliary block, with one side of the bottom right-angle bracket near the back plate fitting against the back plate, and the other side of the bottom right-angle bracket near the baffle fitting against the baffle. The top right-angle bracket increases the contact area with the top plate, improving the installation reliability of the top plate; the bottom right-angle bracket increases the contact area with the baffle, improving the installation reliability of the bottom plate.

[0046] In summary, the auxiliary block design solves the problems associated with direct screw connections, extends service life, and provides convenient assembly and disassembly with high stability.

[0047] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
