[0030] The present application provides a movable display screen structure of an inverter, please refer to Figures 1 to 9As shown, it comprises an inverter host box 100, a terminal cover 200 and a detachable display control device 300. One end of the terminal cover 200 is hinged to the inverter host box 100. A placement slot 210 is arranged in the middle of the terminal cover 200 along the length direction. The detachable display control device 300 is detachably fixed on the placement slot 210. First stoppers 211 are arranged at both ends of the placement slot 210. The detachable display control device 300 is provided with a recessed platform 310 matched with the first stoppers 211 at the side away from the recessed platform 310. The terminal cover 200 is provided with a limiting baffle 213 above the detachable display control device 300. Specifically, the placement slot 210 is a slot formed by downwardly recessing a rectangle. The placement slot 210 corresponds to the detachable display control device 300. The placement slot 210 is arranged in the middle of the terminal cover 200 along the length direction and away from the inverter host box 100. The placement slot 210 is located at the edge of the middle of the terminal cover 200, facilitating the taking of the detachable display control device 300. The placement slot 210 limits the detachable display control device 300 in four directions, i.e. the left end, the right end, the rear end and the bottom end of the detachable display control device 300. The limiting baffle 213 is arranged on the inner side of the placement slot 210 of the terminal cover 200. The limiting baffle 213 limits the protrusion 330 at one side of the detachable display control device 300, i.e. the limiting baffle 213 limits the upward movement of the protrusion 330.

When the detachable display control device 300 is installed in the placement slot 210, the protrusion 330 is located below the limiting baffle 213 by using the height difference. The height difference is covered, so that the terminal cover 200 and the detachable display control device 300 look flat and beautiful as a whole. The other side of the detachable display control device 300 is limited by the recessed platform 310 matched with the first stoppers 211. The two first stoppers 211 block the front end of the detachable display control device 300, i.e. the placement slot 210 limits the detachable display control device 300 in all directions. When the detachable display control device 300 is placed in the placement slot 210, it is stably placed in the placement slot 210 and will not fall off. The detachable display control device 300 can be taken only from the oblique front side. Usually, the detachable display control device 300 is placed in the placement slot 210. If necessary, the detachable display control device 300 is separated from the inverter host box 100, so that the inverter host can be remotely controlled and the running state of the inverter host can be checked.

[0031] It needs to be explained that the L-shaped wiring port 230 is arranged on the placing groove 210, and the L-shaped plate 220 is rotatably connected to the L-shaped wiring port 230.
