Through the arrangement of the second damper 14, the first damper 6 and other structures, when the shell 7 vibrates, the first damper 6 and the shock-absorbing spring 5 support the shell 7 and filter most of the vibration. The remaining vibrations are offset by each other under the action of the second damper 14 and the support spring 15, so that the shell 7 remains stable.

[0022] See also Figure 1-3 Four symmetrically arranged vertical blocks 2 are welded on the bottom plate 1, and screw rods 4 are threadedly installed inside the four vertical blocks 2. An anti-sliding block 3 is welded at the bottom of the screw rod 4. Through the arrangement of the vertical blocks 2, the screw rods 4 and other structures, according to the flatness of the ground where the bottom plate 1 is installed, the screw rods 4 are rotated to adjust the balance of the shell 7. When the shell 7 is in a horizontal state, the screw rods 4 are stopped from being rotated, so that the shell 7 always remains horizontal and the operation is more stable.

[0023] See also Figure 1-3 A sliding groove is opened inside the bottom plate 1, the sliding block 9 is slidably connected inside the sliding groove, a rotating groove is opened inside the connecting rod 11, the round rod 12 is rotatably installed inside the rotating groove, a fixed groove is opened inside the supporting block 13, the round rod 12 is nested inside the fixed groove, a threaded groove 16 is opened inside the vertical block 2, the screw rod 4 is threadedly connected inside the threaded groove 16, and the screw rod 4 and the threaded groove 16 have the same shape and size.

[0024] The specific implementation process of the utility model is as follows: when the control cabinet is in use, the control cabinet will generate large noise and vibration during electrical operation. These noise and vibration may affect the normal operation of the equipment and also affect the service life of the equipment. Therefore, in order to reduce the impact of equipment vibration and noise on the normal operation of the equipment and at the same time extend the service life of the equipment, it is necessary to adopt a suitable shock-absorbing method to isolate these noise and vibration. When the shell 7 vibrates, the first damper 6 and the shock-absorbing spring 5 provide support for the shell 7 and filter most of the vibration. When the remaining vibration causes the shell 7 to shake, the support block 13 descends, and the support block 13 drives the round rod 12 to descend. Under the action of the round rod 12, the connecting rod 11 drives the sliding block 9 to slide, and the sliding block 9 drives the connecting rod 11 to rotate. The second damper 14 and the support spring 15 at the other end of the connecting rod 11 filter the vibration and provide support, so that the shell 7 maintains a stable operating state;

[0025] Furthermore, according to the flatness of the ground at the installation position of the base plate 1, the four screws 4 are rotated respectively to adjust the distance between the anti-sliding block 3 and the base plate 1. When the base plate 1 and the shell 7 are in a horizontal state, the screws 4 are stopped from rotating, so that the control cabinet is more stable and safe during operation.
