Description

Technical Field

[0001] This utility model belongs to the field of folding cabinets, specifically relating to a folding cabinet that is easy to assemble and sturdy. Background Technology

[0002] Folding cabinets, as an innovative type of storage furniture, utilize modular design and compressible storage features to meet diverse spatial needs while achieving efficient space utilization, making them a preferred solution for modern home organization. However, most existing folding cabinets are typically made of plastic to save costs, but plastic folding cabinets have poor load-bearing capacity. When multiple folding cabinets are stacked, the bottom cabinet is prone to damage due to excessive load. On the other hand, using metal materials to make folding cabinets would lead to a significant increase in cost.

[0003] In the prior art, such as patent document CN107684255B, a multi-functional folding cabinet is disclosed, in which the main frame, left and right side panels, cabinet door panel, and bottom plate are all made of plastic. Although folding cabinets made of plastic can reduce costs, they also sacrifice load-bearing capacity, making them prone to damage when multiple folding cabinets are stacked. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a folding cabinet that is easy to assemble and sturdy. By covering the outer periphery of the plastic inner panel with a metal cladding layer, the load-bearing capacity of the folding cabinet is improved, while also taking into account the production cost of the folding cabinet and avoiding a significant increase in production costs.

[0005] This utility model is implemented as follows: A conveniently assembled and sturdy folding cabinet includes a cabinet body. The cabinet body includes a base plate and a main plate and side plates hinged to the base plate. The main plate is hinged to the front and rear sides of the base plate, and the side plates are hinged to the left and right sides of the base plate. The side plates and / or the main plate include a plastic inner panel and a metal cladding layer. The metal cladding layer covers the outer periphery of the plastic inner panel. The hinged connection allows the folding cabinet to be quickly assembled into an unfolded folding cabinet. The plastic inner panel has an outward convex surface, forming a stepped platform that adapts to the contour of the panel. The edge of the metal cladding layer is provided with a folded edge. When the metal cladding layer is connected to the plastic inner panel, the folded edge folds inward and engages with the stepped platform. The base plate is further provided with a metal-clad ring around its perimeter. The edge of the metal-clad ring is provided with a folded or rolled edge, so that the metal-clad ring is fastened to the perimeter of the base plate. The metal cladding layer is used to improve the rigidity of the plastic inner panel, thereby improving the load-bearing capacity of the side panels and / or main panels, and preventing easy damage when multiple folding cabinets are stacked. Compared with side panels or main panels made of metal, the metal cladding layer uses less metal material, reducing the production cost of the side panels or main panels, thus enabling the folding cabinet to improve its load-bearing capacity while taking into account the production cost of the folding cabinet. The metal-clad ring not only improves the strength of the base plate, but also makes the base plate more coordinated with the side panels and main panels, thereby improving the aesthetics of the folding cabinet.

[0006] The side panel also includes a first plug-in part made of plastic. The main board is provided with a first plug-in slot that is adapted to the first plug-in part. When the main board and the side panel are unfolded, the first plug-in part is inserted into the first plug-in slot. The first plug-in part and the first plug-in slot are used to improve the stability between the side panel and the main board, prevent the side panel and the main board from becoming loose, and thus improve the reliability of the folding cabinet.

[0007] It also includes a separately configured top plate. When the main board and side panels are unfolded, the top plate snaps onto the top of the main board and side panels from top to bottom; when the main board and side panels are folded, the top plate stacks on top of the folded cabinet. By snapping together with the main board and side panels, the top plate further improves the stability between the main board and side panels, making the connection between them more reliable; on the other hand, it increases the load-bearing capacity of the folding cabinet when stacked, further improving the reliability of the folding cabinet.

[0008] Preferably, both the metal cladding layer and the metal cladding ring are made of stainless steel. The metal cladding layer covers all or part of the exposed surface of the main board or side panel, and the metal cladding ring covers all or part of the exposed surface of the bottom plate. When the folding cabinet is unfolded, the plastic inner panels of the main board and side panels, as well as the surface of the bottom plate, are not exposed or are only partially exposed. Since the plastic inner panels and bottom plate are usually injection molded from plastic, their surfaces may have defects such as air bubbles. Compared to carbon steel sheet metal parts, stainless steel not only has better strength, further improving the strength of the main board, side panels, and bottom plate, but also conceals the surface defects of the bottom plate and plastic inner panels caused by injection molding, further improving the aesthetics of the folding cabinet.

[0009] Preferably, the main board located on the front side of the base plate includes a mounting plate and a door panel hinged to the mounting plate. The mounting plate has a retrieval opening, which can be opened or closed by rotating the door panel. The retrieval opening is used to retrieve and place items inside the folding cabinet. When multiple folding cabinets are stacked, the retrieval opening facilitates the retrieval of items from the cabinets below, improving the convenience of use and the number of cabinets that can be stacked, thereby increasing the storage capacity of the folding cabinets.

[0010] Specifically, the door panel is provided with a first magnetic unit, and the mounting plate is provided with a second magnetic unit corresponding to the first magnetic unit. When the door panel is closed, the first magnetic unit and the second magnetic unit are magnetically connected. The first magnetic unit and the second magnetic unit are used to prevent the door panel from being opened accidentally, improving the reliability of the door panel, thereby preventing dust from falling inside the folding cabinet and improving the storage effect of the folding cabinet.

[0011] Preferably, the first plug-in portion includes a pressing portion and a blocking portion arranged sequentially from the end inwards. The first plug-in groove has a through hole through which the pressing portion and the blocking portion pass. When the first plug-in portion is inserted into the first plug-in groove, the pressing portion and the blocking portion pass through the through hole, and the blocking portion abuts against the end face of the through hole. The blocking portion is used to prevent the side plate from loosening after being connected to the motherboard. When the blocking portion abuts against the end face of the through hole, the blocking portion can prevent the first plug-in portion from coming out of the first plug-in groove, thereby improving the reliability and firmness of the connection between the motherboard and the side plate. The pressing portion is used to disengage the first plug-in portion from the first plug-in groove. When the pressing portion is pressed, the blocking portion undergoes elastic deformation, causing the blocking portion to disengage from the end face of the through hole, thereby allowing the first plug-in portion to come out of the first plug-in groove, while simultaneously ensuring the reliability of the connection between the side plate and the motherboard and the ease of folding.

[0012] Preferably, the side panel further includes a second connector, and the motherboard further includes a second connector slot corresponding to the second connector. When the motherboard and side panel are unfolded, the second connector is inserted into the second connector slot. The second connector and the second connector slot further improve the reliability of the connection between the side panel and the motherboard, making the connection between the motherboard and the side panel more robust.

[0013] Preferably, the side panel is provided with a first fastening part, and the top panel is provided with a second fastening part corresponding to the first fastening part. When the top panel is snapped onto the main panel and the side panel, the first fastening part and the second fastening part are snapped together. The top panel and the side panel also have outwardly protruding flanges on their corresponding sides, with the second fastening part aligned centrally with the flanges. The first and second fastening parts improve the connection reliability of the top panel, preventing accidental detachment and further improving the stability of the folding cabinet after unfolding. The flanges are used to remove the top panel when the folding cabinet is folded, providing a force point for removal and making removal more convenient. Furthermore, when the second fastening part and the flange are aligned centrally, the force on the top panel is more even during removal, reducing wear and tear and extending the service life of the top panel.

[0014] Specifically, the first fastening part includes a first transition surface that gradually decreases in size from top to bottom, and the second fastening part includes a second transition surface that gradually decreases in size from bottom to top. When the first and second fastening parts are engaged, the first and second transition surfaces are wedge-shaped. The first and second transition surfaces are used for transition during the installation of the top plate, allowing the top plate to deform gradually during installation. This reduces the instantaneous deformation of the top plate during installation, avoids transitional deformation of the top plate, and makes the installation of the top plate smoother, thereby improving the service life and installation convenience of the top plate.

[0015] Preferably, the bottom of the base plate is provided with a locking groove, and the top plate is provided with a locking part. When multiple folding cabinets are stacked, the locking groove of the upper folding cabinet engages with the locking part of the lower folding cabinet. The locking part is used to prevent the stacked folding cabinets from sliding accidentally, thus improving the safety of the stacked folding cabinets.

[0016] Preferably, the side panel has a positioning part at its bottom, and the bottom plate has a positioning groove that matches the positioning part. When the side panel is unfolded, the positioning part engages with the positioning groove. The positioning groove is used to position the side panel after it is unfolded, facilitating the docking of the first insertion part with the first insertion groove and improving the ease of operation when the folding cabinet is unfolded.

[0017] Preferably, the bottom of the base plate is also equipped with detachable casters. The casters are used for the convenience of moving the folding cabinet.

[0018] The beneficial effects of this utility model are:

[0019] This utility model proposes a convenient and robust folding cabinet.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-9 As shown, a convenient and sturdy folding cabinet includes a cabinet body. The cabinet body includes a base plate 1, a main plate 3 hinged to the base plate 1, and side plates 2. The main plate 3 is hinged to the front and rear sides of the base plate 1, and the side plates 2 are hinged to the left and right sides of the base plate 1. The side plates 2 include a plastic inner panel 21 and a metal cladding layer 22. The metal cladding layer 22 covers the outer periphery of the plastic inner panel 21. The hinged connection allows the folding cabinet to be quickly assembled into an unfolded folding cabinet. A metal cladding ring 14 is also provided around the base plate 1. The edge of the metal cladding ring 14 is rolled so that the metal cladding ring 14 is fastened to the periphery of the base plate 1. The metal cladding ring 14 not only improves the strength of the base plate 1, but also makes the base plate 1 more coordinated with the side plates 2 and the main plate 2, thereby improving the aesthetics of the folding cabinet.

[0033] In this embodiment, the plastic inner panel 21 is made of polypropylene, and both the metal cladding layer 22 and the metal cladding ring 14 are made of stainless steel. The metal cladding layer 22 covers the entire exposed surface of the side panel 2, and the metal cladding ring 14 covers part of the exposed surface of the bottom plate 1. When the folding cabinet is unfolded, the plastic inner panel 21 of the side panel 2 and the bottom plate 1 are not exposed. Since the plastic inner panel 21 and the bottom plate 1 are usually injection molded from plastic, their surfaces may have defects such as air bubbles. Compared with carbon steel sheet metal parts, stainless steel not only has better strength, further improving the strength of the side panel 2 and the bottom plate 1, but also conceals the surface defects of the bottom plate 1 and the plastic inner panel 21 caused by injection molding, further improving the aesthetics of the folding cabinet. In other embodiments, the plastic inner panel 21 can be made of other plastic materials; the metal cladding layer 22 can be made of other metal materials.

[0034] The plastic inner panel 21 protrudes outward to form a stepped platform 211 that matches the panel's contour. The metal cladding layer 22 has a folded edge at its edge. When the metal cladding layer 22 is connected to the plastic inner panel 21, the folded edge folds inward and engages with the stepped platform 211. The metal cladding layer 22 is used to improve the rigidity of the plastic inner panel 21, thereby increasing the load-bearing capacity of the side panel 2 and preventing damage when multiple folding cabinets are stacked. Compared with the metal side panel 2, the metal cladding layer 22 uses less metal material, reducing the production cost of the side panel 2 or the main panel 3. This allows the folding cabinet to improve its load-bearing capacity while also reducing its production cost.

[0035] In this embodiment, the main board 3 located on the front side of the base plate 1 includes a mounting plate 31 and a door panel 32 hinged to the mounting plate 31. The mounting plate 31 has a retrieval opening 311, and the retrieval opening 311 can be opened or closed by rotating the door panel 32. The retrieval opening 311 is used to retrieve and place items inside the folding cabinet. When multiple folding cabinets are stacked, the retrieval opening 311 facilitates the retrieval and placement of items from the folding cabinets stacked below, improving the convenience of use after stacking and the number of cabinets that can be stacked, thereby increasing the storage capacity of the folding cabinets.

[0036] Specifically, the door panel 32 is provided with a first magnetic unit, and the mounting plate 31 is provided with a second magnetic unit corresponding to the first magnetic unit. When the door panel 32 is closed, the first magnetic unit and the second magnetic unit are magnetically connected. The first magnetic unit and the second magnetic unit are used to prevent the door panel 32 from being opened accidentally, thereby improving the reliability of the door panel 32, preventing dust from falling inside the folding cabinet, and improving the storage effect of the folding cabinet.

[0037] In this embodiment, the first magnetic unit and the second magnetic unit are magnets.

[0038] In this embodiment, the bottom of the base plate 1 is provided with a snap-fit ​​groove 12, and the top plate 4 is provided with a snap-fit ​​part 41. When multiple folding cabinets are stacked, the snap-fit ​​groove 12 of the upper folding cabinet engages with the snap-fit ​​part 41 of the lower folding cabinet. The snap-fit ​​part 41 is used to prevent the stacked folding cabinets from sliding accidentally, thereby improving the safety of the stacked folding cabinets.

[0039] In this embodiment, the side panel 2 has a positioning part 212 at its bottom, and the bottom plate 1 has a positioning groove 11 that matches the positioning part 212. When the side panel 2 is unfolded, the positioning part 212 engages with the positioning groove 11. The positioning groove 11 is used to position the side panel 2 after it is unfolded, which facilitates the docking of the first insertion part 214 with the first insertion groove and improves the ease of operation when the folding cabinet is unfolded.

[0040] The side panel 2 also includes a first plug-in part 214 made of plastic. The main board 3 is provided with a first plug-in slot that is adapted to the first plug-in part 214. When the main board 3 and the side panel 2 are unfolded, the first plug-in part 214 is inserted into the first plug-in slot. The first plug-in part 214 and the first plug-in slot are used to improve the stability between the side panel 2 and the main board 3, prevent the side panel 2 and the main board 3 from becoming loose, and thus improve the reliability of the folding cabinet.

[0041] In this embodiment, the first plug-in portion 214 includes a pressing portion 2141 and a blocking portion 2142 arranged sequentially from the end inward. The first plug-in groove has a through hole through which the pressing portion 2141 and the blocking portion 2142 pass. When the first plug-in portion 214 is plugged into the first plug-in groove, the pressing portion 2141 and the blocking portion 2142 pass through the through hole, and the blocking portion 2142 abuts against the end face of the through hole. The blocking portion 2142 is used to prevent the side plate 2 from loosening after being connected to the main board 3. When the blocking portion 2142 abuts against the end face of the through hole, the blocking portion 2142 can prevent the first plug-in portion 214 from coming out of the first plug-in groove, thereby improving the reliability and firmness of the connection between the main board 3 and the side plate 2. The pressing part 2141 is used to disengage the first plug-in part 214 from the first plug-in groove. When the pressing part 2141 is pressed, the blocking part 2142 undergoes elastic deformation, causing the blocking part 2142 to disengage from the end face of the through hole, thereby disengaging the first plug-in part 214 from the first plug-in groove. This also takes into account the reliability of the connection between the side plate 2 and the main board 3 and the convenience of folding.

[0042] In this embodiment, the side panel 2 is further provided with a second insertion part 215, and the main board 3 is further provided with a second insertion slot corresponding to the second insertion part 215. When the main board 3 and the side panel 2 are unfolded, the second insertion part 215 is inserted into the second insertion slot. The second insertion part 215 and the second insertion slot further improve the reliability of the connection between the side panel 2 and the main board 3, making the connection between the main board 3 and the side panel 2 more secure.

[0043] It also includes a separately configured top plate 4. When the main board 3 and side panels 2 are unfolded, the top plate 4 snaps onto the top of the main board 3 and side panels 2 from top to bottom; when the main board 3 and side panels 2 are folded, the top plate 4 stacks on top of the folded cabinet. By snapping onto the main board 3 and side panels 2, the top plate 4 further improves the stability between the main board 3 and side panels 2, making the connection between them more reliable; on the other hand, it increases the load-bearing capacity of the folding cabinet when stacked, further improving the reliability of the folding cabinet.

[0044] In this embodiment, the side panel 2 is provided with a first fastening part 213, and the top panel 4 is provided with a second fastening part 43 corresponding to the first fastening part 213. When the top panel 4 is snapped onto the main panel 3 and the side panel 2, the first fastening part 213 and the second fastening part 43 are snapped together. The top panel 4 and the side panel 2 are also provided with outwardly protruding flanges 42 on their corresponding sides, and the second fastening part 43 is centered and aligned with the flanges 42. The first fastening part 213 and the second fastening part 43 are used to improve the connection reliability of the top panel 4, prevent the top panel 4 from accidentally detaching, and further improve the stability of the folding cabinet after unfolding. The flanges 42 are used to remove the top panel 4 when the folding cabinet is folded, providing a force point for removing the top panel 4, making the removal of the top panel 4 more convenient. Moreover, when the second fastening part 43 and the flange 42 are centered and aligned, the force on the top panel 4 is more even when it is removed, reducing the wear of the top panel 4 and improving the service life of the top panel 4.

[0045] Specifically, the first fastening part 213 includes a first transition surface that gradually decreases in size from top to bottom, and the second fastening part 43 includes a second transition surface that gradually decreases in size from bottom to top. When the first fastening part 213 and the second fastening part 43 are engaged, the first transition surface and the second transition surface are wedge-shaped. The first transition surface and the second transition surface are used for transition during the installation of the top plate 4, allowing the top plate 4 to gradually deform during installation, reducing the instantaneous deformation of the top plate 4 during installation, avoiding transitional deformation of the top plate 4, and making the installation of the top plate 4 smoother, thereby improving the service life and installation convenience of the top plate 4.

[0046] In this embodiment, the bottom of the base plate 1 is also provided with detachable casters 13. The casters 13 are used for the convenience of moving the folding cabinet.

[0047] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model.
