[0002] Low-voltage cabinets are suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. They are used for power transmission, distribution and power conversion. There are multiple sets of components installed inside the low-voltage cabinet. The components need to be regularly inspected or replaced to ensure the stable operation of the low-voltage cabinet. Therefore, a low-voltage cabinet that is easy to replace internal components is needed.

[0003] The existing technology has the following shortcomings: when installing the internal components of the existing low-voltage cabinet, most of them need to first use bolts to fix the rack, and then use bolts to fix the components. When replacing the components, it is more troublesome, and the bolts will damage the low-voltage cabinet shell. At the same time, when wiring the components, it is not convenient to adjust the distance between the components, which is not conducive to the replacement and installation of the components;

[0004] In the prior art, "A low-voltage electric control cabinet for easy replacement of components" with publication number CN210111338U uses sockets and posts to install and fix components, but the position of the sockets is fixed, which makes it inconvenient to adjust the distance between components and to quickly replace the components as a whole.

The limiting plate is mounted at one end of the fixing rod. The pulling rod is穿设安装 (inserted and installed) on both sides of the limiting plate. The pressing plate is mounted at one end of the pulling rod. The two groups of second springs are mounted between the pressing plate and the limiting plate.

[0007] As a further preference of this technical solution, the clamping component includes two groups of limiting rods, multiple sliding blocks, a fixing plate, fixing bolts, multiple first springs, and a limiting part.
