[0030] A clamping mechanism for clamping a ventilation duct is provided on the back of the top of the inverter body 1 and at the vent 101. During the actual use of the inverter body 1, a ventilation duct needs to be used to connect the vent 101 to guide the heat dissipation of the entire inverter body 1. The clamping mechanism includes:

[0031] An adjustment plate 5, the adjustment plate 5 is fixedly connected to the back side of the top of the inverter body 1, and an adjustment member is arranged in the middle of the adjustment plate 5;

[0032] The clamping parts are symmetrically slidably sleeved on both ends of the adjustment plate 5 along the horizontal and transverse center, and the horizontal and transverse positions of the clamping parts are adjusted by the adjustment parts.

[0033] Specifically, the clamping parts include:

[0034] Sliding blocks 7, multiple sliding blocks 7 are slidably sleeved on the outer wall of the adjusting plate 5, a transmission block 701 for transmission connection between the multiple sliding blocks 7 and the adjusting member is provided, and a rotation opening is provided on the front of the bottom of the sliding block 7;

A plurality of transmission blocks 701 are all connected in a sliding manner and inserted in the sliding opening and are threadedly sleeved with the outer wall of the adjustment screw 6. A threaded through groove is provided in the middle part of the transmission block 701 along the horizontal and transverse direction. The inner wall thread of the threaded through groove is matched with the outer wall thread of the adjustment screw 6. Through the cooperation between the two, when the adjustment screw 6 is rotated, with the cooperation of the thread, the transmission block 701 moves horizontally and transversely according to the rotation direction of the adjustment screw 6.

After the duct connection is completed, the rotation of the clamping block 8 is released. Driven by the restoring force of the torsion spring 9, the clamping block 8 completes the clamping and fixation of the ventilation duct.
