[0023] See attached Figure 1-3 A combined power switch cabinet includes a trolley room bottom plate 1, side plates 13 are symmetrically arranged on both sides of the trolley room bottom plate 1, the lower edge of the side plate 13 is fixedly connected to the trolley room bottom plate 1, a cabinet door 3 is rotatably installed on the front side of one side plate 13 through a plurality of hinges, a locking mechanism is arranged between the trolley room bottom plate 1 and the cabinet door 3, the locking mechanism is installed in a rectangular groove 7 on the trolley room bottom plate 1, the rectangular groove 7 is arranged on the trolley room bottom plate 1 at one end close to the trolley room opening, one side of the rectangular groove 7 is fixedly connected with a lifting groove 8, and the outlet of the lifting groove 8 is in the same direction as the trolley room opening.

[0024] In this embodiment, the interlocking mechanism includes an arc block 5, a U-shaped locking block 6, an elastic body, a guide cylinder 12 and a guide column 14. The arc block 5 is lifted and telescopically installed in the rectangular groove 7, and the U-shaped locking block 6 is lifted and installed in the lifting groove 8. The lower end of the arc block 5 is fixedly installed with a limit block 9, and the limit block 9 is lifted and installed in the rectangular groove 7. The size of the limit block 9 is larger than the size of the upper opening of the rectangular groove 7, which is used to limit the lower end of the arc block 5 from upwardly escaping from the rectangular groove 7. A card groove 2 is provided on the upper end surface of the U-shaped locking block 6, and the lower end of the cabinet door 3 is also provided with a card groove 4 that is mutually engaged with the upper end surface of the U-shaped locking block 6. The upper right end of the U-shaped locking block 6 is fixedly connected to the limit block 9;

[0025] The elastic body is specifically composed of a return spring 10, which is used to elastically lift and lower the arc block 5 and install it in the rectangular groove 7. The upper end of the return spring 10 is fixedly installed on the lower side end surface of the limit block 9, and the upper end of the guide column 14 is fixedly installed on the lower end of the arc block 5. The lower end of the guide column 14 is lifted and retracted in the inner cavity of the guide cylinder 12.

Figure 3 Only when the chassis 2 is close to the opening of the trolley room, that is, when the circuit breaker on the chassis 2 is in the disconnected position, the lower bottom surface of the chassis 2 will press the upper end of the arc block 5 into the rectangular groove 7, and the downwardly moving arc block 5 will drive the U-shaped lock block 6 to move downward synchronously, so that the upper end surface of the U-shaped lock block 6 moves downward away from the part of the lower end of the card slot 4, thereby releasing the restriction of the U-shaped lock block 6 on the cabinet door 3, unlocking it, and then the cabinet door 3 can be opened;

[0028] When the chassis 2 moves to the right away from the opening of the trolley room, that is, the circuit breaker on the chassis 2 is in the working position, the chassis 2 is away from the arc block 5, and the compressed return spring 10 will automatically push the arc block 5 upward to expose the upper opening of the rectangular groove 7, and drive the U-shaped locking block 6 and the card slot 4 at the lower end of the closed cabinet door 3 to engage with each other, thereby locking the cabinet door 3.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
