[0036] The support structure 2 includes a U-shaped support plate 201 and a connection block 202;

[0037] The two connecting blocks 202 are respectively fixed on the outer walls at the ends of the two vertical sections of the U-shaped support plate 201; the mounting holes on the connecting blocks 202 are fixed to the mounting plate in the control cabinet by screws; wherein, the inner cavity of the U-shaped support plate 201 is inserted and matched with the bottom end of the inverter body 1.

[0038] The utility model provides a U-shaped support plate 201 and a connecting block 202, which can support the inverter body 1 when the inverter body 1 is installed, so that the inverter body 1 does not need to be supported by a worker when it is against the mounting plate in the control cabinet, thereby facilitating the installation of the inverter body 1. This solves the problem of inconvenience caused by the need for workers to lift and hold down the inverter body 1 while screwing in the screws when installing the inverter.

[0039] Specifically, a through hole 2011 is provided on the inner bottom wall of the U-shaped support plate 201 , and the through hole 2011 corresponds to the wiring location at the bottom end of the inverter body 1 ; the wiring at the wiring location at the bottom end of the inverter body 1 is conveniently connected through the through hole 2011 .

[0040] Furthermore, the support structure 2 also includes a fixed plate 203, a baffle 204, a movable plate 205 and a spring 206;

[0041] The fixed plate 203 is fixed on the horizontal side of the front end of the U-shaped support plate 201; the baffle 204 is inserted into the through hole opened at the inner end of the fixed plate 203; wherein, the top of the baffle 204 is limitedly matched with the front end of the bottom of the inverter body 1; the movable plate 205 is fixed at the bottom end of the baffle 204; two springs 206 are symmetrically arranged between the fixed plate 203 and the movable plate 205, and the two ends of the spring 206 are fixedly connected to the fixed plate 203 and the movable plate 205 respectively, and the elastic coefficient of the spring 206 is selected and used by the technicians in this profession according to the actual situation.

[0042] The utility model has the advantage of limiting the bottom front end of the inverter body 1 supported on the U-shaped support plate 201 by setting a fixed plate 203, a baffle 204, a movable plate 205 and a spring 206, blocking the bottom front end of the inverter body 1, so that the inverter body 1 is stabilized on the U-shaped support plate 201, and there is no need to press the inverter body 1 during installation.
