Technical Field

[0001] This utility model relates to the field of storage box technology, and in particular to a folding frame and storage cabinet. Background Technology

[0002] A storage cabinet is a piece of furniture or storage device used to store and organize various items. Functionally, it primarily provides a separate, spatially defined area to centrally store scattered items, making homes, offices, or other spaces more tidy and organized. For example, in a home environment, storage cabinets can be used to separately store different types of items such as clothing, toys, documents, and tableware, preventing clutter caused by random pile-ups. Structurally, storage cabinets typically have one or more enclosed or semi-enclosed spaces. These spaces can be drawer-style, like a file cabinet under a desk, where drawers can be smoothly pulled out and pushed in for easy storage and retrieval of small items such as stationery and papers; or they can be cabinet-door style, like a wardrobe, where the doors open to reveal internal hanging rods, shelves, and other structures for hanging clothes or folding bedding.

[0003] Currently, there are countless styles of storage cabinets on the market, but most of them have the following drawbacks:

[0004] (1) Most storage cabinets on the market require screws and other accessories, as well as corresponding tools, for assembly. Assembly takes a long time, and if the accessories are missing or the consumer is not familiar with the installation skills, the product cannot be assembled.

[0005] (2) Most of the storage cabinets on the market have a lot of packaging padding and lining, resulting in large overall packaging size and heavy weight, and high packaging and transportation costs.

[0006] (3) Most existing storage cabinets on the market cannot guarantee good stability of their frame structure while satisfying folding storage, which makes the user experience poor.

[0007] Based on this, the present invention proposes a folding frame and storage cabinet to solve the problems mentioned above. Utility Model Content

[0028] Furthermore, the end of the lateral folding rod has an arc-shaped pressing part, and the end of the vertical folding rod has a receiving groove;

[0029] When both the horizontal and vertical folding rods are fully extended, the arc-shaped pressing part is located inside the receiving groove and abuts against the inner sidewall of the receiving groove.

[0030] Furthermore, the side walls at both ends of the fixed support rod are provided with first connecting through holes for installing rivet parts.

[0031] Furthermore, the end face of the fixed support rod is provided with a second connecting through hole for installing rivet parts on both sides.

[0032] Furthermore, the end faces of the two upper fixed support rods have positioning recesses, and the end faces of the two lower fixed support rods have positioning protrusions that match the positioning recesses.

[0033] This utility model also provides a storage cabinet, including the folding frame, drawers and cover as described above;

[0034] The drawer is located inside the folding frame to provide storage space;

[0035] The end face of the cover plate has multiple rivets, which cooperate with the second connecting through hole at the top of the folding frame to allow the cover plate to be detachably installed on the top of the folding frame.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] (1) The folding frame provided by this utility model realizes the folding function of the folding frame by setting four fixed support rods, four vertical folding rods and four horizontal folding rods.

[0062] The following is a more detailed description of a folding frame and storage box according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0063] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0064] Example 1

[0065] like Figure 1-2 As shown, this embodiment proposes a folding frame, including a fixed support rod 1, a horizontal folding rod 2, and a vertical folding rod 3;

[0066] There are four fixed support rods 1, which are parallel to each other and arranged in a rectangular shape. Two fixed support rods 1 on the same horizontal plane are connected to a horizontal folding rod 2 at both ends, and two fixed support rods 1 on the same vertical plane are connected to a vertical folding rod 3 at both ends.

[0067] When both the vertical folding rod 3 and the horizontal folding rod 2 are fully extended, the fixed support rod 1, the horizontal folding rod 2, and the vertical folding rod 3 combine to form a hexahedral frame structure, as shown below. Figure 1 As shown.

[0068] When both the vertical folding rod 3 and the horizontal folding rod 2 are fully folded, the four fixed support rods 1 come together to form a long, rectangular cubic structure. The vertical folding rod 3 and the horizontal folding rod 2 are completely folded and stored inside the fixed support rods 1. Figure 2 As shown.

[0069] In the above embodiments, when the folding frame is in the fully unfolded state, the folding frame has a hexahedral frame structure, which can serve as the main skeleton of the storage cabinet. When the folding frame is in the fully folded state, the folding frame has a long and narrow cubic structure, which ensures that the folding frame occupies a better volume after folding, thereby reducing the product's packaging and transportation costs.

[0070] In the above embodiment, the main body of the vertical folding rod 3 is secured by a first fastener, the main body of the horizontal folding rod 2 is secured by a second fastener, and the end of the horizontal folding rod 2 is secured to the fixed support rod 1 by a third fastener so that the end of the vertical folding rod 3 is clamped between the side of the fixed support rod 1 and the horizontal folding rod 2.

[0071] The first, second, and third fasteners provide comprehensive stability to the folding points of the folding frame, ensuring excellent stability of the hexahedral frame structure formed after the folding frame is unfolded, thus guaranteeing the stability of the storage cabinet with the folding frame as the main skeleton.

[0072] In the above implementation process, specifically, in conjunction with reference... Figure 3 The main body of the vertical folding rod 3 includes two hinged straight rods, and the first fastener includes a long strip-shaped connecting post 31.

[0073] The connecting post 31 is installed at the end of one straight rod of the vertical folding rod 3, and the other straight rod of the vertical folding rod 3 has a fixing groove 32 on its inner side;

[0074] When the vertical folding rod is fully unfolded, the connecting post 31 is embedded and locked in the fixing groove 32, which effectively stabilizes the main body of the vertical folding rod 3 after it is unfolded.

[0075] Combined with reference Figure 4-6 The main body of the transverse folding rod 2 includes two hinged straight rods, and the second fastener includes an elastic block 21.

[0076] The elastic block 21 has a first circular protrusion 22 on its end face;

[0077] The two straight rods of the transverse folding rod 2 each have the elastic block 21 and the first groove 23 that matches the first circular protrusion 22 on the end face of their connection.

[0078] When the horizontal folding rod 2 is fully unfolded, the first circular protrusion 22 is inserted into the first groove 23, which effectively stabilizes the main body of the horizontal folding rod 2 after it is unfolded.

[0079] Combined with reference Figure 7 The third fastener includes a second circular protrusion 11;

[0080] The second circular protrusion 11 is disposed on the fixed support rod 1;

[0081] The transverse folding rod 2 has a second groove 25 that matches the second circular protrusion 11;

[0082] When the transverse folding rod 2 is fully extended, the second circular protrusion 11 is inserted into the second groove 25, which effectively stabilizes the end of the transverse folding rod 2 after it is fully extended.

[0083] Combined with reference Figure 8 The fourth fastener includes a third circular protrusion 14;

[0084] The third circular protrusion 14 is disposed on the fixed support rod 1;

[0085] The end sidewall of the vertical folding rod 3 has a third groove 34 that matches the third circular protrusion 14;

[0086] When the vertical folding rod 3 is fully extended, the third circular protrusion 14 is inserted into the third groove 34, which effectively stabilizes the end of the vertical folding rod 3 after it is fully extended.

[0087] Furthermore, in conjunction with reference Figure 9 The horizontal folding rod 2 has an arc-shaped pressing part 24 at its end, and the vertical folding rod 3 has a receiving groove 33 at its end. When both the horizontal folding rod 2 and the vertical folding rod 3 are fully extended, the arc-shaped pressing part 24 is located in the receiving groove 33 and abuts against the inner side wall of the receiving groove 33, so that the end of the vertical folding rod 3 is clamped between the side of the fixed support rod 1 and the horizontal folding rod 2, thereby achieving further stabilization of the end of the vertical folding rod 3 after it is fully extended.

[0088] In one specific embodiment, the side walls at both ends of the fixed support rod 1 are provided with first connecting through holes 12 for installing rivet parts.

[0089] By setting the first connecting through hole 12, a stable connection can be achieved between multiple horizontally placed folding frames.

[0090] Specifically, the connection between multiple horizontally placed folding frames is as follows: Figure 10 The rivet a shown has a plug b1 and a plug b2 at each end. Figure 11 As shown, two folding frames are placed horizontally. Plug b1 is inserted into the first connecting through hole 12 of one folding frame, and plug b2 is inserted into the first connecting through hole 12 at the corresponding position of the other folding frame, thus achieving a stable horizontal connection between the two folding frames.

[0091] Meanwhile, the end face of the fixed support rod 1 is provided with a second connecting through hole 13 for installing rivet parts on both sides.

[0092] The second connecting through hole 13 enables a stable connection between multiple vertically stacked folding frames.

[0093] Specifically, the connection between multiple vertically stacked folding frames can also be achieved using rivets a as described above. For example... Figure 12 As shown, two folding frames are stacked vertically. Plug b1 is inserted into the second connecting through hole 13 of one folding frame, and plug b2 is inserted into the second connecting through hole 13 at the corresponding position of the other folding frame, thus achieving a stable vertical connection between the two folding frames.

[0094] It should be noted that the rivet a disclosed above is only one type of plastic rivet in the prior art. When connecting two folding frames, other types of plastic rivets can also be used, such as plastic rivets with two umbrella-shaped plugs, plastic rivets with two tree-shaped protruding plugs, etc., which will not be elaborated here.

[0095] Furthermore, the end faces of the two upper fixed support rods 1 in the folding frame have positioning recesses 16, and the end faces of the two lower fixed support rods 1 have positioning protrusions 15 that match the positioning recesses 16.

[0096] When multiple folding frames are connected vertically, the positioning protrusion 15 in the upper folding frame engages with the positioning recess 16 in the lower folding frame, further improving the stability of the vertical connection of multiple folding frames.

[0097] In the specific embodiments described above, multiple folding frames can be stably and freely combined, serving as the main external framework of the modular storage cabinet and ensuring its stability. For the free combination of multiple folding frames, users can choose to purchase multiple folding frames and matching rivets to assemble them themselves, making assembly simple. Alternatively, users can request the manufacturer to assemble, package, and ship the components, which also effectively improves the user experience.

[0098] Example 2

[0099] Combined with reference Figure 13 This embodiment proposes a storage cabinet, which uses a folding frame as proposed in Embodiment 1 as the main skeleton, and specifically includes drawers 4 and cover plates 5.

[0100] The drawer 4 is placed inside the folding frame to provide storage space;

[0101] The cover plate 5 is detachably installed on top of the folding frame.

[0102] In the above embodiments, the storage cabinet adopts a folding frame as proposed in Embodiment 1 as the main skeleton. Its drawers 4 and cover 5 are detachable from the folding frame. At the same time, the folding frame can be folded into a long strip-shaped cubic structure with four fixed support rods 1 as the main outline, reducing the product's packaging and transportation costs.

[0103] Meanwhile, during assembly, users only need to pull the fixed support rod 1 of the folding frame to form a hexahedral frame structure, then insert the drawer 4 into the hexahedral frame structure formed by the folding frame, and finally fasten the cover plate 5 on the top of the hexahedral frame structure formed by the folding frame. The operation is simple, without the need for tools and complex connectors, which reduces the assembly difficulty of the product and improves the user experience.

[0104] Specifically, refer to Figure 14-16When unfolding the folded frame, first apply a vertical tension F1 to the fixed support rod 1 of the folded frame to gradually unfold the vertical folding rod 3 of the folded frame. After the vertical folding rod 3 of the folded frame is fully unfolded, apply a horizontal tension F2 to the fixed support rod 1 of the folded frame to gradually unfold the horizontal folding rod 2 of the folded frame. The operation is simple.

[0105] To help users understand how to unfold the folding frame, optionally, an indicator arrow (not shown in the figure) can be set on the fixed support rod 1 to indicate the direction of force application, and a serial number can be marked on it.

[0106] When the user needs to fold the unfolded folding frame, simply remove drawer 4 from the folding frame and remove the cover 5, then fold the folding frame. The folding operation can be deduced from the unfolding operation, so it will not be elaborated here. Folding the folding frame makes it convenient for users to carry and move the storage cabinet.

[0107] Furthermore, the folding frame is secured at all 360 degrees by the first, second, and third fasteners, ensuring excellent stability of the hexahedral frame structure formed after unfolding. The storage cabinet uses this folding frame as its main skeleton, resulting in excellent stability after the individual cabinets are assembled. At the same time, the folding frames can be stably connected horizontally and stacked vertically, allowing users to stably and freely combine multiple storage cabinets to customize the desired modular storage cabinet, thereby meeting their personalized needs for storage space and further enhancing the user experience.

[0108] Specifically, to illustrate how to customize the desired modular storage cabinet, we will explain using a combination of three storage cabinets:

[0109] like Figure 17 As shown, the modular storage cabinet includes three storage cabinets, which are stacked vertically. The folding frames of two adjacent storage cabinets are connected by rivets a. Each of the three folding frames has a drawer 4, and a cover 5 is installed on the top folding frame.

[0110] like Figure 18 As shown, the modular storage cabinet includes three storage cabinets arranged horizontally. The folding frames of two adjacent storage cabinets are connected by rivets a. Each of the three folding frames has a drawer 4, and each of the three folding frames has a cover 5 installed on its top.

[0111] Modular storage cabinets can also be placed and connected using vertical stacking and horizontal arrangement methods, such as... Figure 19 As shown.

[0112] Of course, the personalization of modular storage cabinets is not only reflected in the different arrangements of the cabinets, but also in the choice of drawers 4 and lids 5. Users can choose different materials and colors of drawers 4 and lids 5 to match and use according to their personal preferences.

[0113] In the above embodiments, after placing multiple storage cabinets, users do not need to use rivets a for connection. This makes it more convenient to take out and put in storage cabinets located at high places. Due to the setting of positioning recessed grooves 16 and positioning protrusions 15 in the folding frame, a certain stability between vertically stacked storage cabinets can also be guaranteed.

[0114] In one specific embodiment, in conjunction with reference to Figure 20 The end face of the cover plate 5 has multiple rivets, and the rivets on the cover plate 5 cooperate with the second connecting through hole 13 on the top of the folding frame.

[0115] Specifically, the rivets on cover plate 5 are made using the following methods: Figure 20 The rivet c shown has a plug d at one end and the other end of the rivet c is fixed to the cover plate 5. By inserting the plug d into the second connecting through hole 13 at the top of the folding frame, the cover plate 5 and the folding frame can be stably installed. When it is necessary to disassemble the cover plate 5, simply pull the cover plate 5. The operation is simple.

[0116] In an optional embodiment, the storage cabinet also includes casters (not shown in the figure), which are installed at the bottom of the folding frame and can be inserted into the second connecting through hole 13 at the bottom of the folding frame by rivets c as described above, making installation convenient and improving the flexibility of the storage cabinet.

[0117] Furthermore, the casters are equipped with foot brakes to ensure the storage cabinet's stability.

[0118] Of course, the second connecting hole 13 at the bottom of the folding frame is not limited to installing casters; it can also be used to install support legs to suspend the storage cabinet and improve its moisture-proof effect. The installation method of the support legs is the same as that of the casters, so it will not be described in detail here.

[0119] In summary, the folding frame and storage cabinet provided by this utility model have the following advantages compared with the prior art:

[0120] (1) The folding frame provided by this utility model realizes the folding function of the folding frame by setting four fixed support rods, four vertical folding rods and four horizontal folding rods. After folding, the vertical folding rods and horizontal folding rods are completely stored in the fixed support rods, forming a long strip-shaped cubic structure with the four fixed support rods as the main outline, which ensures that the folding frame occupies a better volume after folding, thereby reducing the packaging cost and transportation cost of the product.

[0121] (2) The folding frame provided by this utility model is a regular hexahedral frame structure after unfolding. The folding points of the folding frame are stabilized in all directions by the first fastener, the second fastener and the third fastener, which ensures the excellent stability of the regular hexahedral frame structure formed after unfolding.

[0122] (3) The storage cabinet provided by this utility model allows users to simply pull the fixed support rod of the folding frame to form a hexahedral frame structure during assembly. Then, the drawer is inserted into the hexahedral frame structure formed by the folding frame, and the cover plate is fastened on the top of the hexahedral frame structure formed by the folding frame. The operation is simple and does not require tools or complex connectors, which reduces the assembly difficulty of the product and effectively improves the user experience.

[0123] (4) The storage cabinet provided by this utility model has good stability after being assembled individually, and users can make stable and free combinations of multiple storage cabinets to meet their own personalized customization needs for storage space and further improve the user experience.

[0124] (5) The storage cabinet provided by this utility model has a design where the drawers and cover are separable from the folding frame. At the same time, the folding frame can be folded into a long cube structure with four fixed support rods as the main outline, which reduces the packaging cost and transportation cost of the product, and at the same time makes it convenient for users to carry and move the storage cabinet.

[0125] Obviously, 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 of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
