The stabilizing plate 9 is installed at the bottom end of the damping spring 8. The limit column 10 is installed on the top end of the stabilizing plate 9 by bolts. The lifting part 11 is installed at the bottom of the switch cabinet body 1. Under the setting of the support plate 4, the protective plate 5, the limit plate 6, the support column 7, and the stabilizing plate 9, the switch cabinet body 1 can be supported and stabilized. Under the setting of the limit column 10, the above-mentioned support structure and the switch cabinet body 1 can be limited and fixed to prevent movement when the support is stable. Under the setting of the damping spring 8, a certain shock absorption effect can be achieved to prevent the limit column 10 from leaving the switch In the cabinet body 1, the lifting part 11 includes two groups of driving motors 12, transmission screws 13, two groups of screw nuts 14, support rods 15, lifting plates 16 and limit rods 17. The two groups of driving motors 12 are symmetrically installed at the bottom end of the switch cabinet body 1 by bolts, the transmission screws 13 are installed at the output end of the driving motors 12, and the two groups of screw nuts 14 are symmetrically sleeved and installed on the outside of the transmission screws 13. The support rod 15 is rotatably installed at the bottom end of the screw nut 14, and the lifting plate 16 is rotatably installed at one end of the support rod 15. The limit rod 17 is installed at the top end of the screw nut 14 by bolts, and the limit column 10 passes through the support column 7 and the support plate 4.

[0024] The utility model provides a switch cabinet with replaceable legs, and the specific working principle is as follows:

[0025] When using the switch cabinet with replaceable legs, the operating conditions in the switch cabinet body 1 can be understood by using the instrument panel 19 and the indicator light 20, and the cabinet door 2 can be opened and closed by using the switch handle 18, which is convenient for users to use. By providing a replacement component 3, when the support structure needs to be replaced, the drive motor 12 is used to drive the transmission screw 13 to rotate, and the rotation of the transmission screw 13 drives the two sets of screw nuts 14 to approach each other, and the movement of the screw nuts 14 drives the support rod 15. The movement of the support rod 15 causes the lifting plate 16 to move downward, and the switch cabinet body 1 can be lifted up, which is convenient for subsequent replacement of the support structure. Since it is no longer pressed by the weight of the switch cabinet body 1, the support column 7 and its accompanying structure fall to the ground, and the user can replace it. After the replacement is completed, the lifting plate 16 is reset. Under the pressure of the weight of the switch cabinet body 1, the damping spring 8 is compressed, and the limit column 10 extends into the switch cabinet body 1, so that the support structure can be limited and fixed, so as to realize the quick and convenient replacement of the support structure and avoid the overall scrapping of the switch cabinet body 1 due to damage to the support legs.
