Technical Field

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

[0002] Electrical cabinets are industrial devices that ensure the stable operation of internal electrical components through physical protection and environmental control systems. They integrate components such as switches, PLCs, and frequency converters, and feature dustproof, waterproof, corrosion-resistant, and electromagnetic shielding functions. Current cabinet assembly is quite cumbersome, typically involving integral welding in a workshop, making them non-disassemblyable and resulting in large space requirements, high transportation costs, and significant pressure on transportation and warehousing. Therefore, there is a need for cabinets that can be directly assembled on-site. Utility Model Content

[0004] A modular cabinet frame includes uprights, horizontal beams, and longitudinal beams. Four uprights are arranged along the Z-direction, four horizontal beams are arranged horizontally along the X-direction, and four longitudinal beams are arranged along the Y-direction. The ends of the uprights, horizontal beams, and longitudinal beams are connected at right angles to form a square frame. The ends of the uprights are provided with a first connecting part and a first limiting step.

[0017] like Figures 1-2As shown, a modular cabinet frame includes upright beams 1, horizontal beams 2, and longitudinal beams 3. Four upright beams 1 are arranged along the Z-direction, four horizontal beams 2 are arranged horizontally along the X-direction, and four longitudinal beams 3 are arranged along the Y-direction. The ends of the upright beams 1, horizontal beams 2, and longitudinal beams 3 are connected at right angles to form a square frame. The ends of the upright beams 1 are provided with a first connecting part 11 and a first limiting step 12. The ends of the longitudinal beams 3 are provided with a first clearance groove 31 and a second clearance groove 32. The ends of the horizontal beams 2 are provided with a second connecting part 21 and a second limiting step 22. The first connecting part 11 is matched and connected to the first clearance groove 31 through a connector 4. The first limiting step 12 is engaged with the end of the longitudinal beam 3. The second connecting part 21 and the second clearance groove 32 are matched and connected through a connector 4. The second limiting step 22 is engaged with the end of the longitudinal beam 3. Specifically, in this embodiment, the vertical beam 1, horizontal beam 2, and longitudinal beam 3 are all straight. The ends of the vertical beam 1, horizontal beam 2, and longitudinal beam 3 are connected at right angles and radiate along the Z, X, and Y directions, respectively. To facilitate disassembly and assembly, we use connectors 4 to connect the vertical beam 1, horizontal beam 2, and longitudinal beam 3, eliminating the need for welding, facilitating transportation after disassembly and assembly, and minimizing the footprint. Simultaneously, to reduce on-site assembly difficulty, we have improved the design of the ends of the vertical beam 1, horizontal beam 2, and longitudinal beam 3. A first connecting part 11 and a first limiting step 12 are provided at the end of the vertical beam 1. During assembly, the end of the longitudinal beam 3 is engaged with the first limiting step 12. At this time, the first connecting part 11 matches the end of the longitudinal beam 3, and the connector 4 can penetrate the first connecting part 11 and insert into the first clearance groove 31 at the end of the longitudinal beam 3, ensuring that there is no protrusion at the connection between the vertical beam 1 and the longitudinal beam 3, and that the outer surface is flat. A second connecting part 21 and a second limiting step 22 are provided at the end of the crossbeam 2. The second connecting part 21 is used to match the second clearance groove 32 of the longitudinal beam 3, and then connected by the connector 4. The second clearance groove 32 ensures that the longitudinal beam 3 and the crossbeam 2 are on the same horizontal plane without protrusion. The second limiting step 22 of the crossbeam 2 is used to engage with the end of the vertical beam 1, serving as a limiting function. Because the assembly precision requirements of the entire frame are high, laser cutting can be used when processing and cutting the vertical beam 1, crossbeam 2, and longitudinal beam 3. The cutting precision is high, and the error is controlled within 0.5mm. It should be noted that after the vertical beam 1, crossbeam 2, and longitudinal beam 3 are assembled into a frame structure, a metal plate is wrapped around the outside of the frame to form a cabinet structure to protect the electrical equipment inside. The metal plate can be connected to the vertical beam 1, crossbeam 2, and longitudinal beam 3 by screws.

[0018] like Figures 2-3As shown, the connector 4 includes countersunk bolts 41 and threaded sleeves 42. Holes 5 are provided on the vertical beam 1, horizontal beam 2, and longitudinal beam 3. The threaded sleeves 42 are detachably installed in each hole 5. The bolts 41 pass through the threaded sleeves 42, connecting the vertical beam 1, horizontal beam 2, and longitudinal beam 3. Specifically, several holes 5 are pre-drilled on the vertical beam 1, horizontal beam 2, and longitudinal beam 3. The connector 4 can directly connect the ends of the vertical beam 1, horizontal beam 2, and longitudinal beam 3 through these holes 5. To improve the structural strength of the connection and prevent stripping or damage to the holes 5 at the connection points of the vertical beam 1, horizontal beam 2, and longitudinal beam 3, threaded sleeves 42 can be pre-inserted into the holes to be connected, and then the countersunk bolts 41 are inserted into the corresponding threaded sleeves 42. The threaded sleeves 42 serve to protect the holes.

[0019] like Figure 3 As shown, the outer circumferential surface of the threaded sleeve 42 is provided with a first oblique ring 421 and a second oblique ring 422. The first oblique ring 421 and the second oblique ring 422 are arranged side by side and spaced apart on the outer circumferential surface of the threaded sleeve 42, and the oblique patterns of the first oblique ring 421 and the second oblique ring 422 are opposite. Specifically, providing the first oblique ring 421 and the second oblique ring 422 in two directions on the outer circumferential surface of the threaded sleeve 42 can increase frictional damping, prevent the threaded sleeve 42 from loosening in the hole 5, and improve its anti-vibration loosening performance. With the groove directions of the first oblique ring 421 and the second oblique ring 422 reversed, after the threaded sleeve 42 is inserted into the hole 5, the countersunk bolt 41 is then inserted during assembly. Whether the countersunk bolt 41 is rotated clockwise or counterclockwise, the first oblique ring 421 and the second oblique ring 422 can cooperate with the inner wall of the hole 5, playing a reverse frictional damping role. This is bidirectional, preventing the threaded sleeve 42 from rotating in the hole 5 when the countersunk bolt 41 is tightened, which would result in it not being tightened properly.

[0020] Specifically, the threaded sleeve 42 is made of copper, while the vertical beam 1, horizontal beam 2, and longitudinal beam 3 are made of aluminum alloy. Installing copper threaded sleeves on a low-strength aluminum alloy substrate can prevent stripping and misalignment of threads, and improve tensile strength.

[0021] like Figure 1 As shown, a support beam 6 for supporting a pallet is detachably installed between two adjacent upright beams 1. The connector 4 passes through the end of the support beam 6 and is inserted into the hole 5 of the upright beam 1. Specifically, the support beam 6 is used to snap onto the pallet (not shown in the figure) to facilitate the support of electrical equipment. At the same time, the support beam 6 is designed to be detachable, which allows for easy adjustment of the installation height of the pallet as needed.

[0022] like Figure 3As shown, a positioning protrusion 121 is provided on the platform of the first limiting step 12, and a notch 33 is provided at the end of the longitudinal beam 3 corresponding to the positioning protrusion 121. Specifically, during assembly, the two ends of the longitudinal beam 3 are first assembled with the ends of the two vertical beams. In order to improve assembly accuracy and avoid misalignment, the positioning protrusion 121 is matched with the notch 33 to position the longitudinal beam, making it convenient for the subsequent connecting parts 4 to be inserted into the corresponding holes 5, thus reducing the assembly difficulty. The cross-section of the protrusion 121 can be designed as a triangle, corresponding to the insertion into the notch 33. The triangular prism-shaped protrusion 121 has a stable structure and is not easily broken after being inserted into the notch 33.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
