Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1 to Figure 2 The utility model provides a technical solution: a grounding interlocking structure of a high-voltage complete ring network cabinet, comprising a cover ring 1, an upper cabinet chamber, an upper box door 12 installed on the front of the upper cabinet chamber, and a lower cabinet door vertically installed directly below the upper box door 12, the lower cabinet door is installed on the front of the lower cabinet chamber, the inner side of the upper box door 12 is fixedly connected with a mounting plate 11, the middle part of the mounting plate 11 is rotatably connected with a rotating rod 2, the top of the rotating rod 2 is fixedly connected with a connecting rod 3, the connecting rod 3 is an L-shaped structure, the short end of the connecting rod 3 is fixedly connected with a cover ring 1, the bottom end of the rotating rod 2 is fixedly connected with an irregular gear 4, the irregular gear 4 is one-fourth the size of a complete gear, a linkage bar 5 is slidably arranged inside the upper cabinet chamber, the linkage bar 5 and the irregular gear 4 are meshed and connected, one end of the linkage bar 5 is bent 90° to have a latch end 7, a spring pin is arranged inside the latch end 7, a socket 8 is installed at a position corresponding to the latch end 7 at the door top of the lower cabinet door, and the latch end 7 cooperates with the socket 8.

[0017] Among them, elastic parts 6 are installed between the two ends of the linkage bar 5 away from the irregular gear 4 and the inner wall of the upper cabinet chamber. The elastic part 6 can be a spring, which can push the linkage bar 5 to move leftward so that the pin end 7 is inserted into the socket 8.

[0018] Among them, a limiting rod 10 is fixedly connected to the middle part of the linkage bar 5 , and the limiting rod 10 is fixedly connected to the inner wall of the upper cabinet chamber. The limiting rod 10 can limit the movement trajectory of the linkage bar 5 .

[0019] A transparent plate 13 is fixedly connected to the middle of the cover ring 1, so that the grounding operation hole can be better observed.

[0020] The centers of the cover ring 1 and the transparent plate 13 are on the same line as the grounding operation hole, so the grounding operation hole can be blocked.
