Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to an extended structure of a modular iron tower control box. Background Technique

[0002] With the continuous development of information technology and communication technology, communication iron towers play a crucial role in modern communication networks. These iron towers not only need to carry a large number of communication antennas, but also need to be equipped with various electronic devices and control systems to support stable signal transmission and network management. Usually, these devices and systems are installed in the control box at the base or around the iron tower.

[0003] The existing communication iron tower control boxes are usually fixedly installed on the mounting rack at the bottom of the iron tower, and each mounting rack can usually only accommodate one iron tower control box. This traditional installation method can meet the requirements when the number of communication devices is small, but with the rapid development of communication technology, the types and quantities of devices to be installed on the iron tower are increasing continuously.

[0004] When the communication devices on the iron tower increase, the internal space of the original iron tower control box may not be sufficient to accommodate the newly added devices. At this time, it is often necessary to add a new iron tower control box. However, due to the design limitations of the traditional mounting rack, the newly added control box cannot be closely installed together with the original control box, but needs to be separately set at a new position. Since multiple iron tower control boxes are installed dispersedly, when maintenance personnel conduct equipment inspection and maintenance, they need to move between different positions, increasing the workload and time cost. Especially in bad weather or night operations, this inconvenience is more prominent. In view of this, we propose an extended structure of a modular iron tower control box. Content of the Utility Model
