[0017] 2. The present invention uses the above working principle to make the guide rail fixed on the clamping hook adapt to the installation of inverter bodies of different sizes. At the same time, the adjustment of the distance between the clamping hooks can make the inverter bodies on different guide rails closely arranged, thereby saving the space inside the chassis shell, so that other components or more inverter bodies can be installed in the chassis shell. The multiple clamping hooks can also be adjusted back and forth to increase the distance between the two guide rails of the whole, thereby increasing the distance between the upper and lower inverter bodies. The larger distance makes it easier for maintenance personnel to repair, install or replace the entire inverter body;

[0018] 3. Pull the overall pulling plate upward so that the pulling plate drives the connecting column and the movable inner circular plate to move upward, thereby causing the movable inner circular plate to squeeze the internal spring tension elasticity, so that the overall first clamping plate moves upward in the movable groove, and then the hook structure on the first clamping plate can be detached from the guide rail. This operation can quickly release the disassembly of the overall inverter body and the connecting plate. The above settings and operations can shorten the time required to install or disassemble the inverter from the inverter chassis, thereby greatly improving the maintenance efficiency of maintenance personnel.

[0029] The hook adjustment mechanism 2 is provided with a small slow-speed motor 201, a support column frame 209 and other components. The support column frame 209 is vertically fixedly welded on one side of the inside of the chassis shell 1. The small slow-speed motor 201 is welded at the lower end of the inside of the support column frame 209. The upper end of the small slow-speed motor 201 is rotatably connected with a rotating long shaft 202.

The middle of the front end of the movable hook block 205 and the fixed hook block 206 are fixedly welded with a connecting hook 10. The rear end of the movable hook block 205 is fixedly welded with a movable connecting block 208, and the rear end of the fixed hook block 206 is fixedly welded with a fixed connecting block 207.

[0030] Furthermore, a guide rod 203 is fixedly welded to the rear end of the rotating long axis 202, and the upper and lower ends of the guide rod 203 are fixedly welded to the upper and lower ends inside the supporting column frame 209, and the fixed connection block 207 at the rear end of the fixed hook block 206 is welded on the guide rod 203; a movable hole is provided in the middle of the upper and lower ends of the movable connection block 208, and the movable connection block 208 and the movable hook block 205 are movably matched with the guide rod 203 through the movable hole;.

[0031] Turning on the small slow-speed motor 201 can drive the rotating long shaft 202 to rotate, wherein the upper and lower sides of the fixed hook block 206 are vertically penetrated with through holes, so that the smooth part of the surface of the rotating long shaft 202 and the fixed hook block 206 can be relatively movable and matched, so that the rotation of the rotating long shaft 202 cannot drive the fixed hook block 206 to rotate, and the rotation of the rotating long shaft 202 drives the four sections of external threads 204 evenly distributed on the rotating long shaft 202 to rotate, and then the external threads 204 and the threaded holes in the middle of the movable hook block 205 are rotated and matched, so that the rotation of the overall rotating long shaft 202 drives the movable hook block 205 to move vertically upward or downward, and the support column frame 20 9 The guide rod 203 is vertically fixedly welded on the rear side of the interior, and the movable connecting block 208 welded on the rear end of the movable hook block 205 can move on the guide rod 203 through the movable hole set through the movable hook block 205.
