Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and particularly relates to an expandable control cabinet. Background Art

[0002] The control cabinet is mainly used to perform electrical operation control on-site mechanical equipment. During use, the control cabinet often needs to be expanded due to the transformation of factory equipment, and some electrical components need to be added inside.

[0003] At present, a Chinese utility model with publication number: CN217643923U discloses an expandable control cabinet, including: a main cabinet, a first expansion cabinet, a second expansion cabinet and a foot, wherein the first expansion cabinet is connected to the main cabinet, the second expansion cabinet is connected to the first expansion cabinet, and the foot is connected to the bottom of the main cabinet, the first expansion cabinet and the second expansion cabinet. Among them, the main cabinet includes: a cabinet body, a cabinet door, a control interface, a first cover plate and expansion cabinet fixing holes. Compared with the traditional technology, the utility model facilitates the expansion of the internal components of the completed control cabinet by adding an expansion cabinet when components need to be added. It has a simple structure and is easy to use.

[0004] The control cabinet in the above patent can only be expanded on one side. Therefore, when installing new electrical components, they can only be installed on the expanded side. If the new electrical components need to be connected to the power equipment on the original side, the electrical components on the original side need to be removed and installed on the expanded position to make room for the new electrical components. This is very troublesome to operate. Although it can be solved by lengthening the power cord connection, the overly long wires are intertwined in the control cabinet, which can easily cause the wires to be entangled and difficult to distinguish, resulting in inconvenience in the arrangement of wires and daily maintenance of the control cabinet. Therefore, it is less practical. Utility Model Content
