[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This embodiment provides an interlocking structure for a high-voltage electrical cabinet, such as... Figures 1 to 9 As shown, it includes: guide pin 1, maintenance switch 2, locking sleeve 3, cabinet door 4, and lock plate 5;

[0032] like Figure 4 As shown, the locking sleeve 3 is fixed to the cabinet body 6 of the electrical cabinet, and a locking bolt 7 (threaded connection) is installed on the locking sleeve 3.

[0033] like Figure 8 and Figure 9 As shown, the lock plate 5 has an unlocking hole 51. The lock plate 5 is slidably mounted on the cabinet 6 and can slide to a position where the unlocking hole 51 is aligned with the locking bolt 7.

[0034] like Figure 4As shown, the maintenance switch 2 is detachably mounted on the cabinet 6, and is positioned on the sliding path of the lock plate 5. The maintenance switch 2 prevents the lock plate 5 from sliding to the position where the unlocking hole 51 aligns with the locking bolt 7. Figure 4 For example, the lock plate 5 needs to slide to the right to align the unlocking hole 51 with the locking bolt 7.

[0035] In practical applications, a maintenance switch mounting bracket is fixed on cabinet 6, such as... Figure 9 As shown, the maintenance switch 2 is inserted into the maintenance switch mounting base;

[0036] like Figure 6 and Figure 9 As shown, two guide pins 1 are fixed on the cabinet body 6, and the cabinet door 4 is slidably installed on the cabinet body 6 through the guide pins 1. The position of the cabinet door 4 is constrained by the locking bolt 7 and the two guide pins 1.

[0037] like Figure 7 and Figure 9 As shown, a locking hole 41 is provided on the cabinet door 4, and the bottom of the locking bolt 7 in the locking sleeve 3 can be inserted into the locking hole 41 to prevent the cabinet door 4 from sliding along the guide pin 1.
