[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A grounding interlocking structure, such as Figure 1 , Figure 2 As shown, the grounding interlocking structure is located inside the switch cabinet. The switch cabinet includes a cabinet panel 1. A transmission rod 3 is rotatably provided on one side of the cabinet panel 1. A circuit breaker is installed below the transmission rod 3. The transmission rod 3 is connected to the operating rod of the circuit breaker through a linkage transmission method. A movable plate 4 is slidably provided on the other side of the cabinet panel 1. A cabinet door is rotatably provided on one side of the cabinet panel 1. A slot is opened on the cabinet panel 1. A lock plate 11 is fixed on the cabinet door. One end of the movable plate 4 passes through the cabinet panel 1.

[0029] When the cabinet door is closed, the lock plate 11 fixedly installed on the cabinet door is inserted into the groove on the cabinet panel 1.

[0030] like Figure 3 As shown, a U-shaped piece 12 is fixedly provided on the inner side of the cabinet panel 1. A vertically arranged locking rod 6 is slidably provided on the U-shaped piece 12. After the locking rod 6 extends upward from the U-shaped piece 12, it is locked with the locking plate 11 to fix the locking plate 11.

[0031] A support plate 13 is fixedly provided on one side of the U-shaped part 12, and a transmission part 5 is rotatably provided on one side of the support plate 13. A mating groove 9 is provided at one end of the transmission part 5, and a mating shaft 91 is fixedly provided at the other end. A mating shaft 91 is also fixedly provided on the side of the moving plate 4.

[0032] The movable plate 4 is slidably connected to the mating groove 9 on the transmission component 5 via the mating shaft 91. A connecting plate 61 is fixedly provided on one side of the locking rod 6. The connecting plate 61 is also provided with a mating groove 9. The connecting plate 61 is slidably connected to the mating shaft 91 on the transmission component 5 via the mating groove 9. By moving the movable plate 4 towards the U-shaped component 12, the transmission component 5 can be pushed to rotate on the support plate 13, which drives the locking rod 6 to move downward. Conversely, by pressing the end of the movable plate 4 that extends out of the cabinet plate 1 to contact the movable plate 4, the movable plate 4 is pushed back into the cabinet, which controls the locking rod 6 to move upward. The locking rod 6 fixes the locking plate 11.

[0033] In this embodiment, the U-shaped component 12 and the movable plate 4 are connected by a tension spring 7, which causes the movable plate 4 to tend to return to the U-shaped component 12.

[0034] A horizontally arranged straight rod 2 is slidably provided on the inner side of the cabinet panel 1. One end of the straight rod 2 is fixedly connected to the movable plate 4, and the other end is fixedly provided with a limiting protrusion 21.

[0035] A micro switch 8 is fixedly installed on the inner side of the cabinet panel 1. The micro switch 8 is located below the straight rod 2. When the straight rod 2 moves with the moving plate 4 towards the transmission rod 3, the micro switch 8 is activated by pressing the end of the straight rod 2.

[0036] A mounting base 14 is rotatably connected to the end of the transmission rod 3. The mounting base 14 is fixed inside the cabinet panel 1 and is slidably connected to the end of the straight rod 2. The transmission rod 3 passes through the mounting base 14 and rotates on the mounting base 14. A notch 31 is opened on one side of the transmission rod 3. After the limiting protrusion 21 slides into the notch 31, it locks the notch 31.

[0037] When using:

[0038] When opening the door, first release the pressure on the movable plate 4. At this time, the locking rod 6 moves downward, unlocking the cabinet door and opening the equipment. At this time, the straight rod 2 moves towards the cabinet door. After the cabinet door is opened, the limiting protrusion 21 on the straight rod 2 moves to the notch 31 and locks the transmission rod 3. At this time, the transmission rod 3 is in the circuit breaker open state, and the moving contact of the circuit breaker is grounded. If the transmission rod 3 is not in the above open state before opening the door, the straight rod 2 cannot move towards the cabinet door, and the locking rod 6 cannot move down, improving the safety of opening the cabinet door and adding insurance for the use of the equipment.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
