Through the mutual cooperation of the two modes, the movable locking plate 9 is reliably fixed, and the adjustable sealing side panels 6 are quickly and reliably fixed, so that the user can quickly assemble the electrical cabinet, making the use of the electrical cabinet more convenient.

[0037] Therefore, through the mutual cooperation of multiple structures, the user can realize instant disassembly of the electrical cabinet, so that the user can repair the electrical cabinet, saving time and effort. Secondly, through the linkage cooperation of multiple structures, the user can realize rapid assembly of the electrical cabinet, thereby making the use of the electrical cabinet more convenient. In addition, the present invention has a simple structure, is easy to use, has low cost, and has a low failure rate. Through the mutual cooperation of multiple pressure relief mechanisms, the distribution cabinet is prevented from bursting, making the use of the distribution cabinet safer and more reliable, and is worthy of promotion and use.
