The utility model relates to the technical field of lap joint structures, and discloses a quick lap joint structure for a main busbar of a low-voltage switch cabinet, which comprises the lap joint structure, the position of the main busbar is installed through a connecting assembly when the main busbar leaves a factory, and only the extended main busbar and the reserved main busbar need to be connected together in a lap joint manner when the main busbar is installed on site. Compared with an existing mode that the main busbar is installed and lapped at last during installation, the connection mode is simpler and faster in installation, and the first cabinet body and the second cabinet body can be connected and fixed through the connection block and the shell after connection. According to the lap joint structure, through the arrangement of the auxiliary assembly pull block, the pull rod can be pulled more easily during disassembly. And a spring II and a plate body are arranged, so that the spring II pushes th
