[0021] When the vertical folding rods 3 and the horizontal folding rods 2 are all in a fully deployed state, as shown in FIG. 1, the fixed support rods 1, the horizontal folding rods 2 and the vertical folding rods 3 combine to form a hexahedral frame structure.

[0022] When the vertical folding rods 3 and the horizontal folding rods 2 are all fully folded, as shown in FIG. 2, the four fixed support rods 1 approach each other to form a long cubic structure, and the vertical folding rods 3 and the horizontal folding rods 2 are fully folded and stored inside the fixed support rods 1.

[0023] In the above embodiment, when the folding frame is in a fully unfolded state, the folding frame has a hexahedral frame structure, which can be used as the main skeleton of the storage shelf; when the folding frame is in a fully folded state, the folding frame has an elongated cubic structure, which ensures an excellent occupied volume after the folding frame is folded, thereby reducing the packaging and transportation costs of the product.

[0024] In the above embodiment, the main body of the vertical folding rod 3 is stabilized using a first stop member, the main body of the horizontal folding rod 2 is stabilized using a second stop member, and the portion between the end of the horizontal folding rod 2 and the fixed support rod 1 is stabilized using a third stop member, 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.

[0025] The first stop member, the second stop member and the third stop member provide omnidirectional stabilization to the folding movable point of the folding frame, ensuring excellent stability of the regular hexahedral frame structure formed after the folding frame is unfolded, thereby ensuring the stability of the storage shelf using the folding frame as the main skeleton.

[0026] In the above-mentioned implementation process, specifically, referring to FIG. 3, the main body of the vertical folding rod 3 includes two straight rods connected by a hinge, and the first stopper member includes a long-shaped attachment post 31; The attachment post 31 is attached to the end of one straight rod of the longitudinal folding rods 3, and has a fixing groove 32 on the inner side of the other straight rod of the longitudinal folding rods 3; When the longitudinal folding rod is fully unfolded, the attachment post 31 is fitted into the fixing groove 32 and fastened, so as to realize effective stabilization of the main body part of the longitudinal folding rod 3 after it is unfolded.

[0027] 4 to 6, the body portion of the lateral folding rod 2 includes two straight rods connected by a hinge, and the second stop member includes an elastic block 21; The end face of the elastic block 21 has a first circular bump 22, The two straight rods of the horizontal folding rod 2 have a first groove 23 on the end surface of the adjacent ends that are close to each other, the first groove 23 being matched with the elastic block 21 and the first circular bump 22; When the lateral folding rod 2 is fully unfolded, the first circular bump 22 is embedded in the first groove 23, thereby realizing effective stabilization of the body part of the lateral folding rod 2 after it is unfolded.

[0028] Referring to FIG. 7, the third stop member includes a second circular bump 11; The second circular bump 11 is mounted on the fixed support rod 1; The lateral folding rod 2 has a second groove 25 that matches the second circular bump 11; When the lateral folding rod 2 is fully unfolded, the second circular bump 11 is embedded in the second groove 25, realizing effective stabilization of the end of the lateral folding rod 2 after it is fully unfolded.

[0029] Referring to FIG. 8, the fourth stop member includes a third circular bump 14; The third circular bump 14 is mounted on the fixed support rod 1; The end side wall of the longitudinal folding rod 3 has a third groove 34 that matches the third circular bump 14; When the longitudinal folding rod 3 is fully unfolded, the third circular bump 14 is embedded in the third groove 34, thereby realizing effective stabilization of the end of the longitudinal folding rod 3 after it is fully unfolded.

[0030] 9, the end of the horizontal folding rod 2 has an arc-shaped bracing portion 24, and the end of the vertical folding rod 3 has an accommodating groove 33. When the horizontal folding rod 2 and the vertical folding rod 3 are both fully unfolded, the arc-shaped bracing portion 24 is located in the accommodating groove 33 and contacts the inner wall of the accommodating 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, and the end of the vertical folding rod 3 is further stabilized after it is fully unfolded.

[0031] In one specific embodiment, the fixed support rod 1 has a first connecting through hole 12 formed on both side walls thereof for mounting a rivet member.

[0032] By providing the first connection through-holes 12, a stable connection between multiple folding frames arranged horizontally can be achieved.

[0033] Specifically, the connection between multiple folding frames arranged horizontally is achieved by using rivet a shown in Fig. 10, and both ends of rivet a have insert members b1 and b2, respectively. As shown in Fig. 11, two folding frames are arranged horizontally, and insert member b1 is inserted into the first connecting through hole 12 of one folding frame, and insert member b2 is inserted into the corresponding first connecting through hole 12 of the other folding frame, thereby realizing a stable connection between the two folding frames in the horizontal direction.

[0034] Moreover, second connection through holes 13 for attaching rivet members are formed on both sides of the end face of the fixed support rod 1.

[0035] The provision of the second connection through-holes 13 can achieve stable connection between multiple folding frames stacked vertically.

[0036] Specifically, the above-mentioned rivet a can also be used to connect multiple folding frames stacked vertically. As shown in Fig. 12, two folding frames are arranged vertically stacked, and the insert member b1 is inserted into the second connecting through hole 13 of one folding frame, and the insert member b2 is inserted into the second connecting through hole 13 at the corresponding position of the other folding frame, thereby realizing a stable connection of the two folding frames in the vertical direction.

[0037] It should be noted that the rivet a disclosed above is merely a plastic rivet in the prior art, and plastic rivets with other types of structures may also be adopted when connecting two folding frames, such as a plastic rivet with two umbrella-shaped insert members, a plastic rivet with two tree-shaped protrusion insert members, etc., and the description thereof will be omitted here.

[0038] Furthermore, in the folding frame, the end faces of the two fixed support rods 1 located at the upper part have positioning grooves 16, and the end faces of the two fixed support rods 1 located at the lower part have positioning protrusions 15 that match the positioning grooves 16.

[0039] When multiple folding frames are attached vertically, the positioning protrusions 15 on the upper folding frame are engaged with the positioning grooves 16 on the lower folding frame, which further improves the stability of the vertical attachment of the multiple folding frames.

[0040] In the above specific embodiment, the folding frames can be stably and freely combined, and as the main body exoskeleton of the combination storage rack, it ensures the stability of the combination storage rack. For the free combination of the folding frames, the user can choose to purchase the folding frames and the attached rivets and assemble them by himself, which is easy to assemble. In addition, the user can make a request and the manufacturer can assemble them and then package and ship them, which can effectively improve the user's experience. Example 2

[0041] Referring to FIG. 13, this embodiment provides a storage shelf, which uses the folding frame provided in the first embodiment as a main body skeleton, and further includes a drawer 4 and a cover plate 5, The drawer 4 is installed inside the folding frame and is used to provide storage space; The cover plate 5 is removably attached to the top of the folding frame.

[0042] In the above embodiment, the storage shelf uses the folding frame provided in embodiment 1 as the main skeleton, and the drawer 4 and cover plate 5 are all designed to be separable from the folding frame, and the folding frame can be folded into a long cubic structure with four fixed support rods 1 as the main body outline, thereby reducing the packaging and transportation costs of the product.

[0043] Moreover, when assembling, the user only needs to pull the fixed support rod 1 of the folding frame to form a hexahedral frame structure on the folding frame, then insert the drawer 4 into the hexahedral frame structure formed on the folding frame, and cover the top of the hexahedral frame structure formed on the folding frame with the cover plate 5, which is easy to operate and does not require the use of tools or complex connecting parts, thereby reducing the difficulty of assembling the product and effectively improving the user experience.

[0044] Specifically, referring to Figures 14 to 16, when the folding frame is unfolded from the folded state, a vertical tensile force F1 is first applied to the fixed support rod 1 of the folding frame to gradually unfold the vertical folding rod 3 of the folding frame, and after the vertical folding rod 3 of the folding frame is fully unfolded, a horizontal tensile force F2 is then applied to the fixed support rod 1 of the folding frame to gradually unfold the horizontal folding rod 2 of the folding frame, which is easy to operate.

[0045] Optionally, the fixed support rods 1 are provided with indicator arrows (not shown) to indicate the biasing directions and are numbered so that users can easily know how to unfold the folding frame.

[0046] When a user needs to fold the unfolded folding frame, he or she can simply take out the drawer 4 from within the folding frame, remove the cover plate 5, and then fold the folding frame. The folding operation of the folding frame can be inferred from the unfolding operation, and will not be described here. By folding the folding frame, the user can easily carry and transport the storage shelf.

[0047] In addition, the folding frame stabilizes the folding movable point of the folding frame in all directions by the first, second and third stop members, ensuring excellent stability of the regular hexahedral frame structure formed after the folding frame is unfolded. The storage shelf uses the folding frame as the main body skeleton, so that each storage shelf is highly stable after it is assembled, and the folding frames can be stably attached horizontally and stacked vertically. This allows users to stably and freely combine multiple storage shelves to customize their desired combination storage shelves, thereby meeting the demand for customization of their own storage space and further improving the user experience.

[0048] Specifically, three storage shelf combination methods are described here to illustrate how to customize a desired storage shelf combination.

[0049] As shown in FIG. 17, the combination storage shelf includes three storage shelves which are stacked vertically, the folding frames of two adjacent storage shelves are connected by rivets a, each of the three folding frames has a drawer 4, and a cover plate 5 is attached to the folding frame located at the top.

[0050] As shown in FIG. 18, the combination storage shelf includes three storage shelves arranged horizontally side by side, the folding frames of two adjacent storage shelves are connected by rivet a, each of the three folding frames has a drawer 4, and a cover plate 5 is attached to the top of each of the three folding frames.

[0051] The combination type storage shelves may be arranged and connected using a vertical stacking method and a horizontally arranged combination method, as shown in FIG.

[0052] Naturally, the customization of the combination type storage shelf can be realized not only in different arrangement and combination methods of the storage shelf, but also in the selection of drawers 4 and cover panels 5, and users can select and combine drawers 4 and cover panels 5 of different materials and different colors according to their personal preferences.

[0053] In the above embodiment, the user does not need to use rivets a to connect multiple storage shelves after arranging them together, so that storage shelves located at high positions can be easily inserted and removed, and the installation of the positioning grooves 16 and positioning protrusions 15 on the folding frame can ensure a certain stability between the vertically stacked storage shelves.

[0054] In one specific embodiment, referring to FIG. 20, the end surface of the cover plate 5 has a plurality of rivet members, and the rivet members on the cover plate 5 are fitted into the second connecting through-holes 13 on the top of the folding frame.

[0055] Specifically, the rivet member on the cover plate 5 is rivet c shown in Figure 20, one end of the rivet c has an insert member d and the other end of the rivet c is fixed to the cover plate 5. By inserting the insert member d into the second connection through hole 13 at the top of the folding frame, stable attachment of the cover plate 5 to the folding frame is achieved. When it is necessary to remove the cover plate 5, it is easy to operate by simply applying force to pull the cover plate 5.

[0056] In one optional embodiment, the storage shelf further includes a swivel wheel (not shown), which is attached to the bottom of the folding frame and can be inserted into the second connection through-hole 13 at the bottom of the folding frame by the above-mentioned rivet c, which makes it easy to install and improves the flexibility of the storage shelf.

[0057] Furthermore, the swivel wheels have stoppers to ensure good stability of the storage rack.

[0058] Of course, the second connecting through hole 13 at the bottom of the folding frame is not limited to mounting the swivel, but can also be chosen to mount a support leg so as to hang the storage shelf and improve the moisture-proof effect of the storage shelf. The mounting method of the support leg is the same as that of the swivel, and the description is omitted here.

[0059] To sum up, the folding frame and storage shelf provided in the present invention have the following advantages over the prior art: (1) The folding frame provided by this invention is provided with four fixed support rods, four vertical folding rods and four horizontal folding rods, which realizes the folding function of the folding frame. After folding, the vertical folding rods and the horizontal folding rods are completely stored in the fixed support rods, forming a long cubic structure with the four fixed support rods as the main body outline, which ensures a good occupied volume after the folding frame is folded, thereby reducing the packaging and transportation costs of the product. (2) The folding frame provided by the present invention has a regular hexahedral frame structure after being unfolded, and the first stop member, the second stop member and the third stop member provide omnidirectional stabilization to the folding movable point of the folding frame, thereby ensuring the excellent stability of the regular hexahedral frame structure formed after the folding frame is unfolded; (3) In assembling the storage shelf provided by the present invention, the user only needs to pull the fixed support rods of the folding frame to form a hexahedral frame structure on the folding frame, then insert the drawer into the hexahedral frame structure formed on the folding frame, and then place a cover plate on the top of the hexahedral frame structure formed on the folding frame. This is easy to operate and does not require the use of tools or complex connecting parts, reducing the difficulty of assembling the product and thereby effectively improving the user experience. (4) The storage shelf provided by the present invention is stable after being assembled, and users can stably and freely combine multiple storage shelves, thereby meeting the need for customizing their own storage space and further improving the user experience; (5) The storage shelf provided by this invention is designed so that the drawer and cover plate are all separable from the folding frame, and the folding frame can be folded into a long cubic structure with four fixed support rods as the main body outline, which reduces the packaging and transportation costs of the product and makes it easy for users to carry and transport the storage shelf.
