[0002] In the field of power distribution cabinet manufacturing and installation, the splicing and connection structure of the cabinet is a core element determining the equipment assembly efficiency, structural stability, and ease of subsequent maintenance. Currently, the mainstream splicing method for power distribution cabinets is welding. While this ensures structural rigidity, it has the inherent drawback of being non-removable. This limits the cabinet's transport due to its overall size and weight, making it difficult to navigate narrow corridors, elevators, and other confined spaces. Furthermore, partial damage necessitates the complete scrapping of the cabinet, resulting in high maintenance costs. In the current splicing method, the frame of the power distribution cabinet is fixed with bolts, lacking reliable limiting and anti-loosening designs at the splicing points. Long-term exposure to equipment vibration or environmental stress can easily lead to loosening of the connections, affecting the overall stability of the cabinet. Utility Model Content
