[0026] The implementation principle of a frequency converter cabinet with anti-vibration bracket in this application embodiment is as follows: During the handling stage, the caster wheel 11 is locked, and the fixing rod 54 is clamped onto the fixing hook 51, so that one end of the fixing frame 52 touches the ground. At this time, only two operators need to lift one end of the bottom of the cabinet 2 and place it on the auxiliary roller 55, and push the cabinet 2 on the auxiliary roller 55 to move it onto the fixing plate 3. The positioning plate 31 positions the cabinet 2. Then, the auxiliary component 5 is disassembled and stored on the base plate 1. During the fixing stage, the connecting plate 61 and the connecting block are fixed by the fixing bolts 63. Connect 62; during the movement and shock absorption phase, unlock the casters 11 and push the cabinet 2 to move. During the movement, when the cabinet 2 is vibrated, the piston rod 43 drives the slide plate 44 to reciprocate within the mounting cylinder 41. The oil generates resistance through the oil hole, converting kinetic energy into heat energy and consuming it to suppress high-frequency vibration. The shock-absorbing spring 47, which is sleeved outside the mounting cylinder 41, deforms elastically when compressed or stretched, absorbing low-frequency vibration energy and providing secondary buffering. Furthermore, the resistance generated by the damping oil can also act on the shock-absorbing spring 47, enabling the shock-absorbing spring 47 to quickly return to stability.
