[0015] In some embodiments, the end of the rotating member facing away from the corresponding connecting member has an arcuate profile, and a second docking surface is arranged on the rotating member, and the surface profile of the second docking surface matches the arcuate profile;

[0016] The second docking surface on one of the rotating components is arranged adjacent to the first docking surface and surrounds a vacant portion. When the two corresponding rotating components are rotatably connected, the end of one rotating component away from the corresponding connecting component is located in the vacant portion of the other rotating component.

[0018] A portion of the outer circumference of the rotating shaft extends in a preset direction to form an interference section, and a gap is provided between the interference section and the inner wall of the insertion hole for the rotating shaft to rotate;

[0019] Wherein, when the rotating shaft rotates to a certain angle in the insertion hole, the abutment section abuts against the inner wall of the insertion hole to limit further rotation of the rotating shaft.

[0026] 1. In the present application, the rotating connection design of the two support frames allows the support frames to be adjusted according to the shape and thickness of the items, so as to better meet different storage needs. Since the tops of the two support frames can be pressed against the surface of the items, the items can be relatively fixed, avoiding shaking and sliding of the items during the storage process; in addition, this design reduces the number of parts required, thereby reducing production costs and assembly complexity.

[0027] 2. In the present application, a resistance section is designed on the rotating shaft.

[0041] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] In contemporary society, racks are a common daily necessity, widely used in homes, offices, and commercial environments to store and organize various items. However, existing rack designs often have some shortcomings, which limit their convenience and adaptability. For example, many traditional racks are designed with fixed sizes and shapes, which limits their ability to adapt to items of different sizes and shapes. In addition, some racks use elastic connectors to achieve the unfolding and folding of the structure, but these elastic parts are prone to aging and loosening over time, affecting the stability and durability of the racks.

[0043] Based on the problems of the existing rack, refer to the instructions attached Figure 1 The storage rack provided in the present application aims to solve the above-mentioned problems. The unique design improves the flexibility and practicality of the storage rack, simplifies the structure of the storage rack, reduces the assembly process or complexity, and reduces the manufacturing cost.

[0044] Reference Manual Attached Figure 1 and Figure 2The storage rack provided in the present application includes two support frames 1. A connecting portion 11 is provided on each support frame 1, and the connecting portions 11 on the two support frames 1 are designed to match and are rotatably connected. At the same time, the support frame 1 and the connecting portion 11 on the support frame 1 together form a storage space 100 for storing items. The design of the rotatable connection allows the two support frames 1 to rotate relative to each other, so that the size of the storage space 100 can be adjusted as needed to accommodate items of different sizes.

[0045] In actual use, the top of the support frame 1 can be pressed against the surface of the object, and the stability of the support frame 1 and the rotation characteristics of the connecting portion 11 are used to achieve relative fixation of the object, thereby ensuring the safety and stability of the object during storage.

[0046] Based on the above, it can be seen that the design in this embodiment not only simplifies the structure of the rack and reduces the number of components, but also improves the overall stability and durability. When in use, the user can easily adjust the opening and closing angle of the support frame 1 to accommodate items of different sizes and shapes, making the rack more widely applicable.

[0047] In addition, the rack in this embodiment is designed to be easy to install and maintain. Since the complex elastic connection mechanism is omitted, the user can quickly complete the assembly and adjustment of the rack without worrying about the loosening or damage of the traditional elastic parts. This improvement greatly reduces the maintenance cost and also improves the economy and environmental protection of the product.

[0048] Specifically, the hinge point between the corresponding connecting parts 11 on the two support frames 1 is located on the symmetry plane of the entire rack, which ensures the overall balance and symmetry of the rack and improves the stability and aesthetics of the structure. In other words, this design helps to evenly distribute the weight of the items, reduce the pressure on a single support frame, and enhance the overall load-bearing capacity.

[0049] On the other hand, the hinge point serves as the center of the rotation connection, allowing the support frame 1 to rotate around the hinge point, so that when an object is placed in the accommodating space 100, due to the gravity of the object, the two support frames 1 are tightened inwards to achieve the effect of tightly fitting the object. The user does not need to perform complicated adjustments or tightening operations, but simply places the object on the support frame 1, and gravity will drive the support frame 1 to tighten, so that the object can be placed stably.

[0050] The support frame 1 is divided into a top, a middle and a bottom according to its height. The connecting portion 11 is arranged between the middle and the bottom of the support frame 1, so that when the tops of the two support frames 1 are in contact, the storage rack as a whole presents an "A"-shaped structure. This unique structural design enables the storage rack to provide stability while also having excellent adaptability and being able to accommodate items of different sizes and shapes.

[0051] For further information, refer to the manual attached. Figure 4 and Figure 5 Each support frame 1 includes a main frame 12, which is used to provide the necessary strength and stability. The main frame 12 protrudes from its middle part toward the symmetry plane to form a smooth arc-shaped curved structure. The connecting part 11 on each support frame 1 is composed of a connecting member 20 and at least one rotating member 30, wherein the connecting member 20 is fixed on the main frame 12.

[0052] One end of each rotating member 30 is connected to the connecting member 20, and the other end is provided with a rotating connection structure. The rotating members 30 of the two supporting frames 1 realize the rotating connection between the two supporting frames 1 through the corresponding rotating connection structure.

[0053] In this embodiment, through this arrangement, the contact area between the entire rack and the surface of the article is larger. In other words, when the article is placed on the rack, the rack can fit more naturally and tightly to the surface of the article. At the same time, the raised arc profile allows the user to hold the support frame 1 more naturally with his fingers when moving or adjusting the rack, providing a better grip point, making the operation easier and more comfortable.

[0054] On the other hand, this design reduces the gap between the shelf and the items, thus providing better support and stability. At the same time, the smooth transition of the arc curve also reduces the friction on the surface of the items, helping to protect the surface of the items from being scratched.

[0055] It should be noted that in this embodiment, the design of the rotating member 30 can take various forms to adapt to different usage requirements and manufacturing processes. For example, the rotating member 30 can be cylindrical, square or other suitable geometric shapes.

[0056] In order to provide a better user experience and simplify the assembly process, the rotating member 30 can be designed to be elastic. This design allows the user to disassemble and assemble the support frame 1 by simply bending the rotating member 30 when assembling and disassembling the rack. The design of the elastic rotating member 30 not only simplifies the user's operation, but also reduces the need for complex connectors, making the entire rack lighter and easier to carry.

[0057] In addition, the elastic design of the rotating member 30 also helps to improve the stability and durability of the rack. During normal use, the elastic rotating member 30 can absorb and alleviate the impact force caused by placing or removing items, thereby protecting the rack from damage. Of course, in some embodiments, the entire support frame 1 can be configured to have an elastic form.

[0058] On the basis of this embodiment, the connecting member 20 is designed as a straight rod-shaped structure, the extension direction of which is parallel to the bottom of the corresponding main frame 12, and the hinge point between the two rotating members 30 is set at a height higher than the bottom of any main frame 12. Based on the above, when an object is placed in the accommodating space 100, the weight of the object acts on the rotating member 30 and is then transferred to the hinge point. Since the position of the hinge point is higher than the bottom of the main frame 12, or the bottom of the shelf, the rotating member 30 naturally droops under the action of gravity without touching the desktop or other surfaces below, avoiding collision or knocking with the desktop and causing damage.

[0059] In one embodiment, based on the above embodiment, the rotating connection structure includes a rotating shaft 31 and an insertion hole 32. In two corresponding rotating components 30, a rotating shaft 31 is set on one rotating component 30, and an insertion hole 32 is set on the other rotating component 30. Through this arrangement, the rotating shaft 31 can be inserted and rotated in the insertion hole 32, thereby realizing relative rotation between the two rotating components 30, providing the necessary flexibility for the storage rack.

[0060] Moreover, based on the elastic design of the rotating member 30 described above, the user can easily bend the rotating member 30 to disassemble or assemble the rack. For example, the user can simply pull the rotating shaft 31 out of the insertion hole 32 to separate the two support frames 1, thereby conveniently carrying or storing the rack. Similarly, by inserting the rotating shaft 31 into the corresponding insertion hole 32 and fixing it, the user can quickly assemble the rack and use it.

[0061] In addition, the design of the rotating shaft 31 and the insertion hole 32 can also take into account wear resistance and durability. The rotating shaft 31 can be made of materials such as metal or high-hardness plastic to improve its wear resistance; and the inner wall of the insertion hole 32 can be designed with a lubrication groove or coating to reduce friction during rotation and extend the service life.

[0062] In a possible embodiment, the structure of the rotating shaft 31 and the insertion hole 32 can be further optimized to adapt to different usage scenarios and requirements. For example, the rotating shaft 31 can be designed to be retractable, allowing the user to adjust the length of the rotating shaft 31 according to the size of the object, thereby adjusting the distance between the support frames 1. In addition, the insertion hole 32 can be designed to be multi-directional, so that the rotating shaft 31 can rotate in different directions, providing more adjustment options.

[0063] In another embodiment, if Figure 4 As shown, the rotating member 30 is provided with a first docking surface 301 at the end portion of one side away from the corresponding connecting member 20, and the extension direction of the first docking surface 301 is set to be parallel to the length direction of the rotating member 30. When the two corresponding rotating members 30 are rotationally connected, the first docking surfaces 301 of the two can fit each other.

[0064] In the above-mentioned embodiment, the rotating shaft 31 and the insertion hole 32 are arranged on the first docking surfaces 301 of different rotating components 30. Through the precise matching of the rotating shaft 31 and the insertion hole 32 and the mutual fit of the first docking surfaces 301 on the two rotating components 30, the mutual fit of the first docking surfaces 301 also helps to reduce the gap at the connection, thereby providing a smoother and more precise rotation experience; on the other hand, the arrangement in this embodiment ensures the stability of the rotating connection, making the storage rack more stable when bearing weight, and reducing the shaking or displacement caused by unstable connection.

[0065] In addition, the extension direction of the first docking surface 301 is parallel to the length direction of the rotating member 30, making the alignment and installation of the rotating shaft 31 and the insertion hole 32 more intuitive and convenient. When assembling or disassembling the rack, the user can easily align these components without complicated alignment process, which greatly reduces the difficulty of assembly and improves the user experience.

[0066] In one embodiment, different from the above-mentioned embodiment, the rotating member 30 has a curved profile at an end portion of one side away from the corresponding connecting member 20 , so that the rotating member 30 is more smooth visually.

[0067] Moreover, in this embodiment, in addition to the first docking surface 301, the rotating member 30 is also provided with a second docking surface 302, and the surface profile of the second docking surface 302 matches the arc surface profile of the rotating member 30. Due to this arc surface profile, the relative rotation of the two support frames 1 is ensured to be smoother. It can be understood that the design of the arc surface profile enables the rotating member 30 to move smoothly along the corresponding matching surface when rotating, reducing the resistance and friction during the rotation process. More importantly, the second docking surface 302 is arranged adjacent to the first docking surface 301, and together they form a vacant portion, which can be understood from the accompanying drawings, that this vacant portion forms a recessed area on one side of the rotating member 30.

[0068] When two corresponding rotating members 30 are rotationally connected, the arc end of one rotating member 30, that is, the side facing away from the corresponding connecting member 20, will be exactly located in the vacant portion of the other rotating member 30. This matching relationship not only ensures the stability of the rotational connection, but also allows accurate and flexible rotation between the two support frames 1. In addition, the design of the vacant portion provides a clear guide, so that the rotating member 30 can be smoothly positioned and fixed in the correct position. When assembling or adjusting the storage rack, the user can intuitively identify the position of the second docking surface 302 and the vacant portion, thereby easily achieving the alignment and interlocking of the rotating member 30. This intuitive design reduces the difficulty of assembly and improves the user experience of the storage rack.

[0069] In another embodiment, based on the above embodiment, an even number of rotating components 30 are provided in each support frame 1, and these rotating components 30 are evenly distributed along the length direction of the connecting member 20, which can not only evenly distribute the forces on the two support frames 1, but also make the appearance of the storage rack neat and orderly.

[0070] The rotating members 30 are divided into several groups, each group includes two rotating members 30, and the first docking surfaces 301 of the two rotating members 30 in the same group are designed to be arranged facing each other or away from each other. It should be noted that such arrangement of the docking surfaces facing each other or away from each other can effectively avoid the problem of accidental disengagement caused by improper operation or accidental pulling.

[0071] It can be understood that, based on the design of the first docking surfaces 301 of the same group facing or away from each other in the above content, the cooperation between the insertion hole 32 and the rotation axis 31 is not only accurate, but also has a certain directionality. This means that when the two support frames 1 are connected together through the rotating member 30, they can only be inserted and matched in a specific direction, thereby forming an anti-slip mechanism. This design ensures that the rotating member 30 can only be inserted and locked when force is applied in the correct direction, and pulling in other directions will not easily cause the connection to be disengaged.

[0072] Specifically, as shown in the drawings, based on the above embodiment, each support frame 1 is provided with four rotating members 30. In the extension direction of the connecting member 20, the first and second rotating members 30 constitute the first group, and the third and last rotating members 30 constitute the second group.

[0073] In the first group, the first abutting surfaces 301 of the two rotating members 30 are designed to be arranged in opposite directions. When the user tries to apply force in the wrong direction, the rotating members 30 are not easily accidentally disengaged due to the opposite arrangement of the first abutting surfaces 301. The first abutting surfaces 301 of the two rotating members 30 of the second group are arranged in opposite directions, further enhancing the tightness of the fit between the rotating members.

[0074] Furthermore, the first docking surface 301 of the first set of rotating components 30 is provided with a rotating shaft 31, and the first docking surface 301 of the second set of rotating components 30 is provided with an insert, so when the user assembles the storage rack, the first set of rotating components 30 on one support frame 1 is connected to the second set of rotating components 30 on another support frame 1, and half of the installation can be completed first, and the installation of the other half is the same. On the other hand, when installing or disassembling, the user only needs to press or pull the rotating component 30 slightly, without using other tools.

[0075] In one embodiment, Figure 3 and Figure 5 As shown, part of the outer circumference of the rotating shaft 31 extends in a preset direction to form an interference section 311, and an appropriate gap is maintained between the interference section 311 and the inner wall of the insertion hole 32. This gap allows the rotating shaft 31 to rotate freely in the insertion hole 32 to achieve angle adjustment of the support frame 1.

[0076] Specifically, when the rotating shaft 31 rotates to a certain angle in the insertion hole 32, the abutment section 311 will abut against the inner wall of the insertion hole 32, limiting the further rotation of the rotating shaft 31, thereby providing a fixed angle setting for the support frame 1. This limiting mechanism ensures the stability of the storage rack during use and prevents instability or structural damage caused by excessive rotation.

[0077] In addition, the design of the interference section 311 also takes into account ease of use and intuitive operation. When the user adjusts the angle of the support frame 1, the user can clearly feel the feedback when the rotation shaft 31 reaches the preset position, which comes from the contact between the interference section 311 and the inner wall of the insertion hole 32. This design allows the user to accurately know when the desired rotation angle is reached, improving the convenience of operation and the reliability of the storage rack.

[0078] According to this embodiment, it should also be noted that the aperture of the insertion hole 32 directly affects the rotation range of the rotating shaft 31 in the hole. The size of the aperture determines the gap between the abutment section 311 and the inner wall of the insertion hole 32, and this gap is directly related to the angle at which the rotating shaft 31 can rotate. By reducing the aperture, the gap can be reduced, thereby limiting the rotation angle of the rotating shaft 31; conversely, increasing the aperture can increase the gap, allowing a larger rotation range.

[0079] Secondly, the size of the abutment section 311 is also a key factor in controlling the rotation angle. The length and shape of the abutment section 311 determine the position where it contacts the inner wall of the insertion hole 32, thereby determining the limiting effect when the rotation shaft 31 rotates to a certain angle. By adjusting the width of the abutment section 311, the maximum rotation angle that the rotation shaft 31 can reach in the insertion hole 32 can be accurately controlled.

[0080] In practical applications, the rotation angle can be precisely controlled by optimizing the above parameters according to the use requirements of the rack and the expected rotation range. For example, if the rack is mainly used to store small items of relatively fixed size, a smaller rotation angle range can be designed to ensure the stability of the support frame 1; and if it is necessary to accommodate items of different sizes and shapes, the rotation angle range can be appropriately increased to improve the flexibility of the rack.

[0081] In another embodiment, each rotating member 30 has a fitting surface 303 and an inclined surface 304 on the surface facing the accommodating space 100 . The inclined surface 304 of the rotating member 30 is located between the fitting surface 303 and the connecting member 20 , with a smooth transition between the two ends.

[0082] In the storage state, the bottom of the article is closely attached to the contact surface 303 of the rotating member 30, providing the required support for the article. At the same time, the bottom of the article is limited by the inclined surface 304 of the rotating member 30 in the two support frames 1, and this limiting effect ensures the stability of the article on the storage rack and prevents the article from sliding or shifting.

[0083] In addition, the fitting surface 303 of the rotating member 30 may be designed to have anti-slip properties, such as texture or special materials, to increase the friction with the bottom of the object and further improve the stability of the object.

[0084] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
