A cabinet door 2 for closing the opening 11 is provided at the front end of the cabinet 1, and the cabinet door 2 is hinged to the cabinet 1 through a vertically arranged rotating shaft 3, the cabinet door 2 is fixed to the rotating shaft 3, and the rotating shaft 3 is rotatably connected to the cabinet 1. In the embodiment of the present application, the cabinet door 2 is hinged on the left side of the opening 11.

[0039] Reference Figure 2 , Figure 3 The electrical device for preventing electric shock also includes a power supply wire 4, which includes an incoming power section wire 41, an outgoing power section wire 42, and a butt joint assembly 43 located between the incoming power section wire 41 and the outgoing power section wire 42. The butt joint assembly 43 includes a mother component 431 connected to the outgoing power section wire 42 and a subcomponent 432 connected to the incoming power section wire 41, and the subcomponent 432 is plugged into the mother component 431. When the subcomponent 432 and the mother component 431 are plugged together, the incoming power section wire 41 and the outgoing power section wire 42 are connected, and when the subcomponent 432 and the mother component 431 are separated, the incoming power section wire 41 and the outgoing power section wire 42 are disconnected. The incoming power section wire 41 is used to connect to the power source, and the outgoing power section wire 42 is used to connect to the electrical components installed inside the cabinet 1.

[0040] The mother component 431 and the child component 432 are arranged from the front end to the rear end of the cabinet 1. The mother component 431 is fixed on the inner side wall of the cabinet 1, and the child component 432 is movably arranged inside the cabinet 1. When the child component 432 moves toward the rear end of the cabinet 1, the child component 432 is separated from the mother component 431. A linkage mechanism 5 is provided between the cabinet door 2 and the child component 432. Under the action of the linkage mechanism 5, when the cabinet door 2 is opened, the child component 432 is driven to separate from the mother component 431, thereby realizing power off.

[0041] The linkage mechanism 5 includes a driving gear 51 fixed on the rotating shaft 3, a first rack 52 slidably connected to the inner surface of the left side wall of the cabinet 1, a transmission gear 53 rotatably supported inside the cabinet 1 and meshed with the first rack 52, and a linkage gear 54 located between the driving gear 51 and the transmission gear 53, and the linkage gear 54 is rotatably connected inside the cabinet 1. The linkage gear 54 is meshed with the driving gear 51 and the transmission gear 53 respectively. When the driving gear 51 rotates, the transmission gear 53 is driven to rotate by the linkage gear 54.

[0042] The length direction of the first rack 52 is set from the front end to the rear end of the cabinet 1. The first rack 52 is located below the sub-component 432 and the mother component 431. The sub-component 432 is fixed to one end of the first rack 52 toward the rear end of the cabinet 1 through the clamping assembly 6. When the cabinet door 2 is opened, the shaft 3 rotates clockwise, and the driving gear 51 is synchronously driven to rotate with the rotation of the shaft 3. After the driving gear 51 rotates, the transmission gear 53 rotates under the action of the linkage gear 54. With the rotation of the transmission gear 53, the first rack 52 moves toward the rear end of the cabinet 1. The first rack 52 moves toward the rear end of the cabinet 1 to separate the sub-component 432 from the mother component 431.

[0043] Reference Figure 4 The clamping assembly 6 includes a fixed claw 61 fixedly connected to the first rack 52 and a freely arranged movable claw 62, and the movable claw 62 is connected to the fixed claw 61 by a bolt. The sub-component 432 is clamped and fixed between the movable claw 62 and the fixed claw 61.

[0044] Reference Figure 1 , Figure 2 A mounting plate 7 made of insulating material is also provided inside the cabinet 1. The mounting plate 7 is used to install electrical components required by the electrical equipment. The mounting plate 7 is slidably connected inside the cabinet 1. The moving direction of the mounting plate 7 is set from the front end of the cabinet 1 to the rear end of the cabinet 1.

[0045] A driving gear 8 is also provided inside the cabinet 1 and is coaxially arranged opposite to the transmission gear 53. The driving gear 8 is opposite to the middle position in the height direction of the mounting plate 7. The driving gear 8 is connected to the transmission gear 53 through a linkage shaft 81. One end of the linkage shaft 81 is fixed to the transmission gear 53, and the other end of the linkage shaft 81 is fixedly connected to the driving gear 8. A second rack 9 is provided between the driving gear 8 and the mounting plate 7. The length direction of the second rack 9 is provided from the front end to the rear end of the cabinet 1. The second rack 9 is fixedly connected to the mounting plate 7 and the second rack 9 is meshed with the driving gear.

[0046] When the cabinet door 2 is opened, the driving gear 8 rotates coaxially with the transmission gear 53 under the action of the linkage shaft 81. As the driving gear 8 rotates, the second rack 9 moves toward the front end of the cabinet body 1, thereby driving the mounting plate 7 to gradually approach the opening 11 of the cabinet body 1.

[0047] Inside the cabinet 1, the top wall panel of the cabinet 1, the side wall of the cabinet 1 and the bottom wall panel of the cabinet 1 are all fixed with guide rails 12, and the length direction of the guide rails 12 is set from the front end to the rear end of the cabinet 1. The side of the guide rails 12 facing the mounting plate 7 is provided with a slide groove 121 that is set along the length direction of the guide rails 12. The mounting plate 7 is provided with rollers 71 at the positions opposite to the guide rails 12, and the rollers 71 extend into the slide grooves 121 of the corresponding guide rails 12. When the mounting plate 7 moves, the rollers 71 roll in the slide grooves 121 where they are located.

[0048] The implementation principle of an electrical device for preventing electric shock in an embodiment of the present application is as follows:

[0049] When the maintenance personnel are performing maintenance, while opening the cabinet door 2, the driving gear 51 and the linkage gear 54 are linked to drive the transmission gear 53 to rotate. As the transmission gear 53 rotates, the first rack 52 is driven to move toward the rear end of the cabinet body 1. As the first rack 52 moves toward the rear end, the sub-component 432 and the mother component 431 are separated, thereby achieving overall power-off of the electrical components, ensuring that when the cabinet door 2 of the electrical equipment is opened, all the internal electrical components are in a power-off state.

[0050] At the same time, when the cabinet door 2 is opened, the mounting plate 7 approaches the opening 11, so that the mounting plate 7 of the mounting component is moved to the opening 11, so that the maintenance personnel do not need to put their hands and arms into the cabinet body 1 when repairing the electrical components, thereby reducing the maintenance personnel's hands and arms reaching into the cabinet body 1 and accidentally touching other electrical components and causing damage to other electrical components.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
