DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] To further illustrate the content, features, and efficacy of the present disclosure, the following embodiment is provided and described in detail with reference to the accompanying drawings:

Embodiment 1

[0038] This embodiment discloses a storage rack designed to support painting boards or other similar flat objects with attached artwork, thereby facilitating the drying of items affixed to the boards or flat objects. The storage rack comprises a bottom base 3 placed on the ground or any horizontal surface during use, and one or more main frames 1 vertically connected to the base 3. The lowest main frame 1 is directly mounted on the base 3, while other main frames 1 are sequentially mounted on the main frames 1 below them. These main frames create vertical drying spaces for the painting boards. Each main frame 1 further incorporates multiple inclined shelves 2. These shelves create multi-layer storage spaces vertically, with each layer capable of holding one drawing board. All main frames 1 can be disassembled from each other or from the bottom base 3. All shelves 2 can be removed from the main frames 1, facilitating convenient storage of the entire storage rack assembly.

[0039] Specifically, the bottom base 3 in this embodiment is configured as a rectangular frame structure comprising two oppositely arranged side beams 31 and two oppositely arranged end beams 32. A center beam 33 connects the two side beams 31, with its ends respectively connected to the midpoints of the two side beams 31. The side beams 31, end beams 32, and center beam 33 are all fabricated from square hollow sections via mechanical processes such as welding or stamping, forming an integrally molded structure. This configuration provides the bottom base 3 with a top surface 301 and a bottom surface 302. When the bottom base 3 is placed on the ground or a horizontal surface, both the top surface 301 and bottom surface 302 lie horizontally. The top surface 301 of the bottom base 3 is oriented upward during use, while the bottom surface 302 of the bottom base 3 is oriented downward during use. The main frame 1 is connected to the top surface 301 at the location of the center beam 33.

[0040] The center beam 33 is provided with multiple connection holes 331. These connection holes 331 extend through the top surface 301 and bottom surface 302 of the bottom base 3, forming circular apertures that allow fasteners such as bolts to pass through. The fasteners serve to secure and fix the main frame 1 in place. As described above, the main frame 1 may be configured as one or more units. The main frame 1 located at the very bottom is connected and fixed to the center beam 33, while the remaining main frames 1 are sequentially connected to the top of the main frame 1 located below. In this embodiment, two main frames 1 are provided. The main frame 1 is configured as a rectangular frame structure. It includes a mounting base 11 located at the bottom for connecting to the center beam 33. The mounting base 11 is a long, strip-shaped metal plate, and its two side surfaces are respectively the connection surface 112 and the mounting surface 113, with the connection surface 112 facing upward and the mounting surface 113 facing downward. The mounting base 11 is placed parallel to the center beam 33 along its length direction, and the mounting surface 113 in contact with the top surface 301 of the center beam 33. Additionally, the mounting base 11 is provided with a plurality of circular mounting holes 111 extending through both side surfaces, for mounting the mounting base 11 onto the center beam 33. The mounting method for the mounting base 11 and the center beam 33 involves placing the mounting base 11 on the center beam 33, aligning the mounting holes 111 with the corresponding connection holes 331 vertically, passing fasteners such as bolts or pins through the mounting holes 111 and their corresponding connection holes 331, and then securing them with nuts or similar components. This allows the mounting base 11, along with the entire main frame 1, to be fixed to the bottom base 3. In this embodiment, the center beam 33 is provided with four connection holes 331, and correspondingly, the mounting base 11 is also provided with four mounting holes 111. The four connecting holes 331 are arranged in pairs and distributed on both sides of the center beam 33's mid-section. This ensures more balanced force distribution on the center beam 33 when the main frame 1 is mounted via the mounting base 11, thereby enhancing the main frame 1's stability. To further improve the stability of the main frame 1 when connected to the bottom base 3, downward-facing bend sections 114 are provided on both long edges of the mounting base 11, which form a position-limiting groove 115 between the two bend sections 114. When the main frame 1 is mounted on the bottom base 3, the center beam 33 is positioned within the position-limiting groove 115 between the two bend sections 114. This facilitates the positioning of the mounting base 11, ensuring the main frame 1 is securely and stably mounted on the bottom base 3.

[0041] Within each main frame 1, two load-bearing members 12 are mounted on the connection surface 112 of the mounting base 11. The load-bearing members 12 are hollow rod structures designed to create vertical installation spaces for mounting multiple layers of shelves 2. In this embodiment, the load-bearing members 12 are hollow rectangular profiles. They are vertically mounted on the connection surface 112 of the mounting base 11. The two load-bearing members 12 are arranged parallel to each other and fixed to the mounting base 11 via welding or similar methods. The bases of the two load-bearing members 12 are positioned at opposite ends along the length of the mounting base 11, creating a large mounting span between them. This facilitates better support for the drawing boards once the shelves 2 are installed on the load-bearing members 12. Multiple circular insertion holes 121 are continuously formed along the length of each load-bearing member 12 at equal intervals. These insertion holes 121 extend through to the interior of the load-bearing member 12, designed to engage with the shelf 2 for its insertion and installation. Each load-bearing member 12 features two opposing sides for setting the aforementioned insertion holes 121, with the insertion holes 121 on both sides corresponding at the same height. Within each main frame 1, each insertion hole 121 on a load-bearing member 12 corresponds to another insertion hole 121 on a different load-bearing member 12 at the same horizontal level. Thus, both sides of the load-bearing member 12 can accommodate shelf 2 insertion. The shelves 2 can form multiple vertical layers, allowing multiple painting boards to be dried on both sides of the load-bearing member 12, thereby improving space utilization efficiency. Additionally, users can flexibly adjust the number of shelves 2 installed on the load-bearing member 12 based on the height of items requiring drying. This allows for greater spacing between upper and lower shelves 2 compared to continuous installation, enhancing the product's practicality and flexibility.

[0042] A connecting rod 13 is positioned between the tops of the two load-bearing members 12. The connecting rod 13 is a hollow rectangular profile. Both ends of the connecting rod 13 are fixed to the tops of the two load-bearing members 12 via welding or similar methods, thereby forming a rectangular frame for the main frame 1. Similarly, assembly holes 131 are formed in the connecting rod 13. These assembly holes 131 extend vertically through the connecting rod 13 and are used to connect and secure the upper main frame 1 to the lower main frame 1. In this embodiment, four assembly holes 131 are provided. These four assembly holes 131 are arranged in pairs and distributed on both sides of the middle section of connecting rod 13. Assembly holes 131 are used for the connection and fixation of adjacent upper and lower main frames 1. Therefore, based on usage requirements, the user can install another main frame 1 on the connecting rod 13 of the lower main frame 1. This allows multiple main frames 1 to form a taller drying space vertically, facilitating the drying of more painting boards. In this embodiment, the main frame 1 is preferably configured as two: one mounted on the bottom base 3, and the other fixed to the lower main frame 1 via the connecting rod 13 of the lower main frame 1. The connection method between the upper main frame 1 and the lower main frame 1 involves placing the mounting base 11 of the upper main frame 1 parallel to the connecting rod 13 of the lower main frame 1. This positions the connecting rod 13 within the position-limiting groove 115 of the mounting base 11, where it contacts the mounting surface 113. The assembly holes 131 and the mounting holes 111 are aligned vertically. Then, by passing connecting elements such as bolts or pins through the assembly holes 131 and the corresponding mounting holes 111, and securing them with nuts or similar components, the upper main frame 1 can be fixed to the lower main frame 1.

[0043] The shelf 2 features an overall metal rod-like structure. In this embodiment, the shelf 2 comprises two side rods 21 integrally bent and formed, along with an end rod 22 connecting the two side rods 21. The end rod 22 is perpendicular to the side rods 21, giving the shelf 2 an overall U-shaped structure. The connection point between the end rod 22 and the side rod 21 forms an transition arc surface 23, which reduces the likelihood of injury to hands during disassembly of the shelf 2. Both ends of the side rods 21, distant from the end rod 22, integrally feature an insertion section 24. This insertion section 24 is formed by bending the end of the side rod 21 and constitutes a metal rod shorter in length than the side rod 21. The transition between the insertion section 24 and the side rod 21 is smooth, forming an curved arc surface 241. The angle between the insertion section 24 and the side rod 21 can be any angle between 30 and 90. This allows the shelf 2 to form an inclined angle with the horizontal plane when the bottom base 3 is placed on the ground or a horizontal surface after assembly. Preferably, the angle formed between the shelf 2 and the horizontal plane is 15. When combining shelf 2 with main frame 1, insert the two insertion sections 24 of shelf 2 into the two connecting holes 121 located at the same height, thereby connecting shelf 2 between the two load-bearing members 12. Under the force of gravity, the insertion sections 24 hook into the connecting holes 121, with the insertion sections 24 abutting the inner wall of the load-bearing member 12 to achieve self-locking of the shelf 2. At this point, the painting board or other objects to be dried can be placed on the upper part of the shelf 2, which supports the painting board and maintains it at a certain inclined angle. By designing different angles between the insertion section 24 and the side rod 21, the shelf 2 can be positioned at varying inclines relative to the horizontal plane. The rod-shaped structure of the shelf 2 in this embodiment provides substantial open gaps, enabling natural airflow between layers of adjacent shelf 2 to accelerate the drying process of placed items. The inclined placement of shelf 2 applies a horizontal component of gravitational force to items like drawing boards. This allows items to adhere to the inclined surface formed by shelf 2 under their own weight while preventing them from sliding off. It also facilitates easy removal and placement of items. To enhance the stability of shelf 2 installation, multiple support rods 14 connect the two load-bearing members 12 within each main frame 1. Each support rod 14 is horizontally positioned and mounted at the edge below two insertion holes 121 at the same height. When shelf 2 is inserted into insertion holes 121, support rods 14 provide lateral support to both sides of shelf 2, sharing part of the weight it bears and ensuring its stability.

[0044] Furthermore, to facilitate moving the storage rack, wheels 4 are mounted on the bottom surface 302 of the bottom base 3. In this embodiment, it is preferred that the wheels 4 are swivel casters, with four wheels 4 provided. Each of the four wheels 4 is mounted at a corner of the bottom surface 302. These wheels 4 enable the entire storage rack of this embodiment to slide across the ground or a horizontal surface, allowing operators to move the storage rack more conveniently and efficiently. Additionally, to enhance the structural strength of the bottom base 3, a reinforcement plate 34 is provided on the bottom surface 302. The reinforcement plate 34 is positioned perpendicular to the center beam 33, with its two ends fixed to the two end beams 32 respectively, and its middle section fixed to the center beam 33. The reinforcement plate 34 helps distribute part of the weight borne by the center beam 33, thereby ensuring the overall structural strength.

[0045] In the present disclosure, the main frame 1 is detachably connected to the bottom base 3 via the mounting base 11. Adjacent main frames 1 are also detachably connected to each other through the connection between the mounting base 11 and the connecting rod 13. This allows the main frame 1 to be conveniently and quickly detached from the bottom base 3, while adjacent main frames 1 can also be detached from each other. The shelf 2 can be detachably connected to the main frame 1 via the insertion section 24. When assembling shelf 2 onto main frame 1, insert the insertion section 24 of shelf 2 into the insertion hole 121. This causes insertion section 24 to hook into insertion hole 121 and abut against the inner wall of load-bearing member 12, thereby self-locking shelf 2 onto load-bearing member 12 at a specific inclination angle. To remove the shelf 2 from the main frame 1, rotate the shelf 2 in a specific direction and disengage the shelf's insertion section 24 from the insertion hole 121. This facilitates the disassembly of the shelf 2 from the main frame 1, greatly simplifying the transportation and relocation of the storage rack. Additionally, the main frame 1 can accommodate multiple shelves 2 vertically, creating several spaces for placing painting boards. This allows users to dry multiple boards simultaneously. On one hand, it prevents artwork from sticking together when boards are laid flat, making separation and retrieval easier. On the other hand, it significantly enhances spatial efficiency.

[0046] The above describes only embodiments of the present disclosure and is not intended to limit the scope of the present disclosure. For those skilled in the art, various modifications and variations of the present disclosure may be made. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present disclosure shall be included within the scope of the claims of the present disclosure.
