The fixing assemblies 3 are fixed on opposite sides of the cooling fans 2.

[0029] Reference Figure 2 、 Figure 3The fixing assembly 3 includes a connecting block 31, a fixing block 32, and a stopper 33. The connecting block 31 is fixed to the inner surface of the switch cabinet body 1. A hinge 51 is rotatably connected to the connecting block 31. The fixing block 32 and the connecting block 31 are rotatably connected via the hinge 51. The stopper 33 is fixed to the bottom and top of the connecting block 31, respectively. The stopper 33 is perpendicular to the connecting block 31 and abuts the cooling fan 2. When the hinge 51 rotates, the fixing block 32 abuts the cooling fan 2.

[0030] Reference Figure 3 、 Figure 4 The GCS low-voltage withdrawable switch cabinet for heat dissipation also includes a snap-in assembly 4, which includes a plug-in block 41, a snap-in block 42, and a sliding spring 43. A receiving groove 52 for accommodating the sliding spring 43 is provided on the cooling fan 2. The sliding spring 43 is fixed to the bottom of the receiving groove 52, and the sliding spring 43 slides along the length direction of the receiving groove 52. The snap-in block 42 is fixed to the end of the sliding spring 43 away from the bottom of the receiving groove 52, and the sliding spring 43 drives the snap-in block 42 to slide in the receiving groove 52. A plug-in hole 53 is provided on the fixed block 32, and the plug-in block 41 slides axially along the plug-in hole 53. When the plug-in block 41 abuts against the snap-in block 42, the plug-in block 41 continues to slide along the cooling fan 2, and the snap-in block 42 is snapped onto the plug-in block 41.

[0031] Reference Figure 3 、 Figure 4 A shift block 6 is fixed to the clamping block 42. A sliding groove 54 is provided on the cooling fan 2 for the shift block 6 to slide.
