[0002] A distribution cabinet is a general term for a motor control center. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small. Distribution cabinets are divided into power distribution cabinets and lighting distribution cabinets. A distribution cabinet can distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load, providing protection and control for the load. Distribution cabinets are usually installed outdoors and require an installation structure to assemble and fix the bottom of the distribution cabinet.

[0003] During the actual use process, it is necessary to pre-install the installation bracket on the ground and then install the bottom of the distribution cabinet on the bracket. Since the height of the bracket is fixed, it is not flexible to adjust the height, and it is necessary to replace the bracket with a specified height. Therefore, an installation structure at the bottom of a distribution cabinet is proposed to solve the problems pointed out in the above background technique. Content of the Utility Model
