Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Fig. 1 shows a schematic structural view (front side) of an inverter maintenance device according to an embodiment of the present invention; fig. 2 shows a schematic structural view (back) of an inverter maintenance device according to an embodiment of the present invention. Referring to fig. 1 and 2, the present embodiment discloses an inverter maintenance device, which includes a housing 1, a rotating shaft 9, a connecting rod 10, and a cross rod 11.

The surface of the casing 1 is provided with a display panel 2, a key 3, a knob 4 and a binding post 5 in sequence from top to bottom. The display panel 2 is preferably a display screen with fluorescence, so that data on the display panel 2 can be observed more clearly during night maintenance, data can be better fed back to maintenance personnel, and maintenance efficiency is improved. The other surface of the shell 1 opposite to the display panel 2 is sequentially provided with a first groove 6, a second groove 7 and a third groove 8 from top to bottom, and the first groove 6, the second groove 7 and the third groove 8 form an I-shaped groove; the rotating shaft 9 is rotatably connected to the inside of the first groove 6, the rotating angle of the rotating shaft 9 is adjustable, the connecting rod 10 is arranged inside the second groove 7, the cross rod 11 is arranged inside the third groove 8, and the rotating shaft 9, the connecting rod 10 and the cross rod 11 form an I-shaped rotating mechanism.
