[0002] With the development of the times, modular furniture has gradually become popular. Modular furniture is simple to assemble, easy to standardize production and on-site assembly, and is especially popular among DIY enthusiasts. The core design of modular furniture is to divide the furniture into easily assembled units. Modular kits are the components that can be easily combined to form furniture. By combining different modular kits, various required modular units can be formed. Currently, some commonly used modular kits have complex structures and insufficient overall precision. During assembly, on the one hand, it is inconvenient and generally requires special tools, which is not conducive to manual DIY; on the other hand, in actual use, the furniture frame has poor stability and is prone to falling apart. To solve this problem, this utility model proposes a connecting kit (CN202321967891.9) centered on a six-way connector and a splicing rod, based on commonly used modular kits. This connecting kit allows for the rapid assembly of the overall furniture frame according to requirements. However, when installing cabinet doors, the corresponding door hinge mounting positions need to be machined according to the design requirements. This necessitates careful verification of the hinge mounting positions during assembly to ensure they match the drawings; otherwise, reassembly may be necessary. Utility Model Content
