[0038] Embodiment 2:

[0039] Based on the first embodiment, the specific working principle is as follows:

[0040] The ring network metering cabinet is provided with two equipment components 15, the power control component is located at the top of the ventilation box 5, and the metering component is located at the bottom of the ventilation box 5. Two symmetrically distributed slide rails 8 are provided, and the two equipment components 15 slide on the outside of the slide rails 8 through the slide bar 17, so that the equipment component 15 slides as a whole inside the cabinet 1. The equipment component 15 is driven to move by pulling the handle 16, so that the equipment component 15 slides on the outside of the slide rail 8 through the slide bar 17, and then the equipment component 15 is displaced as a whole inside the cabinet 1 until the equipment component 15 is located as a whole outside the cabinet 1, so that it is convenient to inspect and repair the equipment component 15;

[0041] When the device assembly 15 slides on the outside of the slide rail 8 through the slide bar 17, the part of the slide bar 17 extending to the outside of the cabinet 1 will move through the reserved groove 6. At the same time, the movement of the device assembly 15 will drive the installation sleeve 19 to move, so that the installation sleeve 19 drives the positioning block 20 to slide inside the slide groove 9. When the device assembly 15 is completely located inside the cabinet 1, the positioning block 20 will engage with the groove at the inner end of the slide groove 9, thereby fixing the position of the device assembly 15 inside the cabinet 1. When the user pulls the handle 16, the positioning block 20 will compress the spring, so that the positioning block 20 slides upward inside the installation sleeve 19, so that the positioning block 20 slides inside the slide groove 9, and the positioning block 20 does not interfere with the movement of the device assembly 15.

[0042] During the movement of the device component 15, the device component 15 will drive the driven sleeve 12 to slide inside the free sleeve 11, so that the free sleeve 11 follows the driven sleeve 12 to slide inside the fixed sleeve 10, so that during the movement of the device component 15, the fixed sleeve 10, the free sleeve 11 and the driven sleeve 12 form a whole and shrink or extend following the movement of the device component 15.
