Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a split assembly type outdoor ring network box. Background Art

[0002] Outdoor ring network boxes account for the vast majority of distribution network products. Their outdoor ring network boxes include an outer shell and a cabinet. The cabinet is placed and fixed in the box cover outer shell. The outer shell and the cabinet need to be assembled, debugged, and tested as a whole in the factory. After completion, they are transported to the site for installation on the foundation. After external debugging, they can be put into operation. The existing solution is to transport the outer shell to the assembly workshop after welding and spraying. At the same time, the ring network cabinet is assembled and combined, and then transported to the assembly workshop. The combined cabinet is then lifted by a crane and placed inward from the front of the outer shell. However, due to the limitation of the lifting equipment, the cabinet can only enter a small part of the box cover. It takes several people to push it inward to completely enter the shell. The cabinet position needs to be adjusted. The shell base is designed with threads, and the cabinet base is designed with mounting holes. After adjusting the mounting holes to align with the threads, the cabinet is fixed to the shell base with bolts. This assembly method is time-consuming, labor-intensive, and has great safety hazards.
