[0025] At the same time, a front cabinet door 4 is installed on the front face of the cabinet body 1 through a hinge, and two L-shaped limit blocks 7 are symmetrically installed on the top and bottom of the rear side of the cabinet body 1, and a rear cabinet door 5 is slidably installed on the rear side of the cabinet door 1 through the L-shaped limit blocks 7, and a clamping mechanism 6 is arranged inside the rear cabinet door 5, and the rear cabinet door 5 is connected to the L-shaped limit blocks 7 through the clamping mechanism 6.

[0026] At the same time, the middle of the bottom and top of the rear cabinet door 5 are both installed with a locking slide block 51 , and the horizontal end of the L-shaped limiting block 7 is located at the corresponding locking slide block 51 to open a limiting sliding groove 71 .

[0027] In addition, a limit fixing block 9 is fixedly installed between the cabinet body 1 and the L-shaped limit block 7, and the limit fixing block 9 is located on the side away from the clamping mechanism 6, wherein the limit fixing block 9 acts as a limit and resistance for the rear cabinet door 5, thereby facilitating the limiting of the rear cabinet door 5.

[0028] In addition, the clamping mechanism 6 includes a limit rotating plate 61, the middle part of which is rotatably installed inside the rear cabinet door 5 through a rotating shaft, and an extending protrusion 62 is fixedly installed on the side of the limit rotating plate 61 away from the cabinet body 1 and close to the rear cabinet door 5.

[0029] Furthermore, a through hole is opened on one side of the rear cabinet door 5 and located at the corresponding limit rotating plate 61, and a groove is opened in the rear cabinet door 5 and located on one side of the corresponding through hole and on the side away from the extending protrusion 62, and the width of the groove is greater than half the width of its limit rotating plate 61, and a return spring 64 is horizontally connected in the groove, and the other end of the return spring 64 is connected to the limit rotating plate 61.

[0030] In addition, a visual window 8 is provided in the middle of the interior of the front cabinet door 4 and the rear cabinet door 5 , through which the user can observe the condition of the inverter group 3 inside the cabinet body 1 .
