Description

Technical Field

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

[0002] In many scenarios, such as daily life and industrial production, shelves are frequently needed to store various items. While traditional fixed shelves offer a degree of stability, their unchangeable structure means they occupy a significant amount of space when not in use, making storage and transportation extremely inconvenient. For example, in warehouses, a large number of unused fixed shelves occupy valuable storage space, reducing warehouse space utilization. During transportation, fixed shelves, due to their large size, require more transport space, thus increasing transportation costs.

[0003] To address the issue of fixed shelves taking up too much space, some foldable shelves have emerged on the market. However, existing foldable shelves have several shortcomings. The folding and unfolding of some foldable shelves is complex, requiring specific tools and involving cumbersome procedures. This results in a poor user experience, especially in scenarios where frequent unfolding and folding of the shelves is necessary, wasting a significant amount of time and effort.

[0004] Some folding racks, while capable of folding, exhibit poor structural stability when unfolded. The components are not properly coordinated, making them unable to withstand significant weight or external forces. This can lead to wobbling or even collapse when items are placed on them, potentially damaging the stored items and posing safety hazards to surrounding people and the environment. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a multifunctional folding frame.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A multifunctional folding frame includes several horizontal frame groups connected by connecting frame groups. Each horizontal frame group includes a central frame, a flipping rod, and an external support rod. The flipping rod is symmetrically installed on both sides of the head of the central frame, with one end of the flipping rod rotatably connected to the central frame. The external support rod is rotatably installed on the other end of the flipping rod. The connecting frame group includes a double-headed central frame, a top-bent short rod, and a bottom-bent short rod. The top-bent short rod is symmetrically installed on both sides of the head of the double-headed central frame, with one end of the top-bent short rod rotatably connected to the double-headed central frame and the other end of the top-bent short rod rotatably connected to the external support rod. The bottom-bent short rod is arranged parallel to the bottom of the top-bent short rod, with both ends of the bottom-bent short rod rotatably connected to the double-headed central frame and the external support rod, respectively.

[0008] As a preferred embodiment, the central pole frame includes a vertical pole section and a first double-headed component for rotating the flipping rod. The first double-headed component is installed on the inner and outer sides of the head of the vertical pole section, and is fixedly connected to the vertical pole section.

[0009] As a preferred embodiment, one end of the flipping rod is provided with a distal hole corresponding to the first double-headed component, and the other end of the flipping rod is provided with a proximal hole corresponding to the external support rod.

[0010] As a preferred embodiment, the external support rod includes a main rod and right-angle members. The right-angle members are installed on both sides of the head of the main rod and are fixedly connected to the main rod.

[0011] As a preferred embodiment, the double-headed frame includes a connecting central tube and a second double-headed component. The second double-headed component is configured as four sets, and the four sets of second double-headed components are fixedly installed on the inner and outer sides of the upper and lower ends of the connecting central tube.

[0012] As a preferred embodiment, the top-bend short rod includes an upper short rod and a first upturned corner piece rotatably connected to the main rod. The first upturned corner piece is fixedly installed on both sides of one end of the upper short rod, and the other end of the upper short rod is provided with a distal through hole corresponding to the second double-headed piece.

[0013] As a preferred embodiment, the bottom-bend short rod includes a lower short rod and a second upturned corner piece rotatably connected to the main rod. The second upturned corner piece is fixedly installed on both sides of one end of the lower short rod, and the other end of the lower short rod is provided with a proximal through hole corresponding to the second double-headed piece.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: The folding and unfolding functions are achieved through a rotating connection between the components, making operation simple and convenient. For example, the rotating design of the flip rod and external support rod allows users to easily unfold and fold the folding frame without complicated tools or operating procedures. In the unfolded state, the components support each other, forming a stable structure. The reasonable coordination between the central frame, flip rod, external support rod, double-headed central frame, top-bent short rod, and bottom-bent short rod can withstand a certain weight and external force, ensuring the stability of the folding frame, which can be used to place various items. After folding, the components are close together, greatly reducing the space occupied. This allows the folding frame to be easily stored away when not in use, saving storage space; at the same time, it also facilitates transportation and reduces transportation costs.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A multifunctional folding frame includes several sets of horizontal frame groups 1, which are connected by connecting frame groups 2. Each horizontal frame group 1 includes a central frame 11, a flipping rod 12, and an external support rod 13. The flipping rod 12 is symmetrically installed on both sides of the head of the central frame 11, with one end rotatably connected to the central frame 11. The external support rod 13 is rotatably installed on the other end of the flipping rod 12. The connecting frame group 2 includes a double-headed central frame 21, a top-bent short rod 22, and a bottom-bent short rod 23. The top-bent short rod 22 is symmetrically installed on both sides of the head of the double-headed central frame 21, with one end rotatably connected to the double-headed central frame 21 and the other end rotatably connected to the external support rod 13. The bottom-bent short rod 23 is arranged parallel to the bottom of the top-bent short rod 22, with both ends rotatably connected to the double-headed central frame 21 and the external support rod 13, respectively. By setting several sets of horizontal frame groups 1 and connecting them with the connecting frame groups 2, the overall structure of the folding frame is made more stable. The foldable function of the folding frame is achieved through the cooperation of the central frame 11, the flipping rod 12, and the external support rod 13 in the transverse frame assembly 1, as well as the coordinated action of the double-headed central frame 21, the top-bent short rod 22, and the bottom-bent short rod 23 in the connecting frame assembly 2. When unfolded, the components support each other and can withstand a certain weight and external force, ensuring the stability of the folding frame; when folded, the components can be brought closer together, reducing space occupation and facilitating storage and transportation.

[0030] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6The central frame 11 includes a vertical rod portion 111 and a first double-headed member 112 for rotatably mounting the flipping rod 12. The first double-headed member 112 is installed on the inner and outer sides of the head of the vertical rod portion 111 and is fixedly connected to the vertical rod portion 111. The central frame 11 adopts the structural design of the vertical rod portion 111 and the first double-headed member 112, which provides a stable rotatable mounting position for the flipping rod 12. This structure allows the flipping rod 12 to rotate flexibly around the first double-headed member 112 while ensuring the stability of the flipping rod 12 during rotation, avoiding swaying or deviation, thereby improving the overall stability and reliability of the folding frame. One end of the flipping rod 12 is provided with a distal hole 121 corresponding to the first double-headed member 112, and the other end of the flipping rod 12 is provided with a proximal hole 122 corresponding to the external support rod 13. The distal hole 121 and the proximal hole 122 provided on the flipping rod 12 play an important role. The distal hole 121 ensures a long distance between the outer edge of the flip rod 12 and the rotation center. When the flip rod 12 is flipped to the horizontal position, its head can be supported on the top of the middle frame 11, achieving quick positioning. This positioning method is simple and effective, enabling rapid determination of the flip rod 12's position when the folding frame is unfolded, improving operational convenience, and enhancing the stability of the folding frame in the unfolded state. The external support rod 13 includes a main rod 131 and right-angle pieces 132. The right-angle pieces 132 are installed on both sides of the head of the main rod 131 and are fixedly connected to the main rod 131. The external support rod 13 adopts the structure of the main rod 131 and right-angle pieces 132. The right-angle pieces 132 are installed on both sides of the head of the main rod 131, enhancing the structural strength and stability of the main rod 131. The main rod 131 needs to be flipped 270° to open. This specific flipping angle design allows the external support rod 13 to form a reasonable support structure with other components when unfolded, further improving the load-bearing capacity and stability of the folding frame.

[0031] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7The double-headed frame 21 includes a connecting tube 211 and four sets of second double-headed components 212, which are fixedly installed on the inner and outer sides of the upper and lower ends of the connecting tube 211. This structural design provides multiple stable connection points for the top-bent short rod 22 and the bottom-bent short rod 23, enabling them to reliably connect to the double-headed frame 21, thus ensuring the stability of the connecting frame assembly 2 and improving the overall stability of the folding frame. The top-bending short rod 22 includes an upper short rod 221 and a first upward-flipping corner piece 222 rotatably connected to the main rod 131. The first upward-flipping corner piece 222 is fixedly installed on both sides of one end of the upper short rod 221, and the other end of the upper short rod 221 has a distal through hole 223 corresponding to the second double-headed piece 212. The structural design of the top-bending short rod 22, including the upper short rod 221, the first upward-flipping corner piece 222, and the distal through hole 223, allows the top-bending short rod 22 to flexibly rotate and connect with the double-headed middle frame 21 and the external support rod 13. The first upward-flipping corner piece 222 ensures the connection stability between the top-bending short rod 22 and the main rod 131, while the distal through hole 223 corresponds to the second double-headed piece 212, enabling the top-bending short rod 22 to accurately connect with the double-headed middle frame 21 during rotation, realizing coordinated movement between the various components of the folding frame and improving the overall performance of the folding frame. The bottom-bend short pole 23 includes a lower short pole 231 and a second upward-turning corner piece 232 rotatably connected to the main pole 131. The second upward-turning corner piece 232 is fixedly installed on both sides of one end of the lower short pole 231, and the other end of the lower short pole 231 has a proximal through hole 233 corresponding to the second double-headed piece 212. The structural design of the bottom-bend short pole 23, including the lower short pole 231, the second upward-turning corner piece 232, and the proximal through hole 233, ensures a reliable connection between the bottom-bend short pole 23 and the double-headed central frame 21 and the external support pole 13. The outer edge of the top-bent short rod 22, which connects to the double-headed middle frame 21, is relatively far from the rotation center. When flipped to the horizontal position, it can be supported on the top of the double-headed middle frame 21. Meanwhile, the bottom-bent short rod 23, which connects to the double-headed middle frame 21, is relatively short. This design ensures that the bottom-bent short rod 23 will not interfere with the double-headed middle frame 21 during synchronous flipping. This allows the components of the folding frame to move smoothly during folding and unfolding, improving the smoothness of operation and the reliability of the folding frame.

[0032] Working principle:

[0033] In actual deployment, firstly, the flipping rod 12 is flipped upwards around the first double-headed component 112. When it flips to a horizontal position, the head of the flipping rod 12 is supported on the top of the central frame 11, achieving rapid positioning. Then, the external support rod 13 is flipped 270° around the near-end hole 122 of the flipping rod 12, putting it in the deployed state. After the multiple rows of parallel transverse frame groups 1 are deployed simultaneously, the connecting frame group 2 can be deployed. Pulling and moving the distance between the transverse frame groups 1 causes the top bent short rod 22 and the bottom bent short rod 23 to rotate accordingly. While the operator pulls the transverse frame group 1, they manually press down on the double-headed central frame 21, allowing the double-headed central frame 21 to move downwards, which in turn causes the top bent short rod 22 and the bottom bent short rod 23 at both ends to flip downwards. When the top bent short rod 22 flips to a horizontal position, it is supported on the top of the double-headed central frame 21. The bottom bent short rod 23 moves in coordination with the double-headed central frame 21 and the external support rod 13 without interfering with the double-headed central frame 21, thus completing the deployment of the folding frame.

[0034] When folding is required, the process is reversed from unfolding. First, the double-headed middle frame 21 is pulled upward to merge the multiple rows of parallel transverse frame groups 1 together. Then, the outer support rod 13 is rotated 270° in the opposite direction around the near end hole 122 of the flipping rod 12, so that it is rotated to the upper end face of the flipping rod 12. Then, the flipping rod 12 is rotated downward around the first double-headed piece 112, so that it is close to the middle frame 11, and finally the folding of the folding frame is completed.

[0035] The above are preferred embodiments of this utility model. 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 described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
