[0025] As attached Figure 1-6An energy-saving switch cabinet with electric shock protection shown in the figure comprises a cabinet body 1 and a cabinet door 2. An insulating protective pad 3 is fixedly connected to the bottom of the cabinet body 1, which can support and protect the bottom of the cabinet body 1 and the cabinet door 2. A lock block 4 is fixedly connected to the middle of one side of the inner cavity of the cabinet body 1. Through the cooperation of the lock block 4 and the limit turntable 6, the position of the cabinet door 2 is conveniently fixed. A limit turntable 6 is arranged at a position corresponding to the lock block 4 on one side of the cabinet body 1. A handle 7 is fixedly connected to one end of the limit turntable 6. A card slot 5 is provided on the top of the lock block 4, and a first contact plate 13 is provided on the bottom. The limit turntable 6 can be rotated by the handle 7, and the card plate 11 can be conveniently limited by the card slot 5.

[0026] The two sides of the end of the limit turntable 6 away from the handle 7 are respectively fixedly connected with a card plate 11 and a connecting plate 8, one side of the card plate 11 is fixedly connected with an elastic touch ball 12, and one side of the connecting plate 8 is fixedly connected with a first contact 9. A first display light 10 is arranged on the top of the side of the limit turntable 6 close to the handle 7. The limit turntable 6 drives the card plate 11 and the connecting plate 8 to rotate, and the card plate 11 can be conveniently inserted into the inside of the card slot 5 to fix the closure of the cabinet door 2. The elastic touch ball 12 fits with the lock block 4, so that the first display light 10 can be electrically connected with the lock block 4. When the lock block 4 is energized, the first display light 10 is lit, which can directly indicate whether the cabinet door 2 is energized, and the card plate 11 is separated from the lock block 4 by rotating the handle 7. At this time, the first contact 9 fits with the first contact plate 13. When the cabinet door 2 and the limit turntable 6 are energized, the first display light 10 is continuously lit, which can realize the current detection of the cabinet body 1 and the cabinet door 2, avoid electric shock, and improve the protection effect;

[0027] A cabinet current detection mechanism is provided at one side of the bottom of the inner cavity of the cabinet 1, which can detect the current of the cabinet 1 after the cabinet door 2 is opened, so as to remind maintenance personnel and protect against electric shock.

[0028] As attached Figure 3-5 As shown, the cross-sectional shape of the limit turntable 6 is set to an "H" shape, the limit turntable 6 passes through the wall of the cabinet door 2, the handle 7 and the first display light 10 are located on the outside of the cabinet door 2, the first contact 9 and the elastic touch ball 12 are electrically connected to the first display light 10, and the limit turntable 6 can improve the rotation stability of the handle 7, and facilitate the change and rotation of the position of the card plate 11 and the connecting plate 8. The first display light 10 can conveniently display whether the cabinet body 1 and the cabinet door 2 are energized, remind nearby personnel, and play a role in preventing electric shock.

[0029] As attached Figure 2-5As shown, the card plate 11 is adapted to the card slot 5, the card plate 11 is arranged inside the card slot 5, the elastic touch ball 12 is in contact with a side wall of the inner cavity of the card slot 5, the card plate 11 and the connecting plate 8 are perpendicular to each other, and the first contact point 9 corresponds to the first contact plate 13. By clamping the card plate 11 inside the card slot 5, the closing strength of the cabinet door 2 can be improved, and the elastic touch ball 12 can make the card plate 11 fit with the lock block 4, so that the elastic touch ball 12 can detect whether the cabinet 1 is energized. When the cabinet 1 is energized and the lock block 4 is energized, it will be detected by the elastic touch ball 12, so that the first display light 10 is lit, which is convenient for reminding maintenance personnel to avoid electric shock and improve the protection effect.

[0030] As attached Figure 2 , 6 As shown, the cabinet current detection mechanism includes a fixed block 14 fixed at the bottom of the inner cavity of the cabinet 1, a second display light 15 is arranged on the top of the fixed block 14, a second contact plate 16 is fixedly connected to the top of one side of the fixed block 14, and a limiting groove 17 is arranged at the bottom of the other side. The second display light 15 is used to conveniently display whether the current is energized, so as to conveniently remind maintenance personnel to avoid electric shock and improve the protection effect.

[0031] As attached Figure 2 , 6 As shown, a stabilizing plate 18 and a stabilizing rod 19 are inserted in the middle of the limiting groove 17, and a top plate 21 and a movable plate 20 are fixedly connected to both ends of the stabilizing plate 18 and the stabilizing rod 19 respectively. The top plate 21 is adapted to the limiting groove 17, and the top plate 21 is arranged on one side of the limiting groove 17. By squeezing the top plate 21 by the cabinet door 2, the top plate 21 can be located inside the limiting groove 17, thereby avoiding the normal closing of the cabinet door 2.

[0032] As attached Figure 2 , 6 As shown, a spring 22 is sleeved on one end of the stabilizing rod 19 close to the top plate 21, and the spring 22 is arranged in the middle of the limiting groove 17. A second contact 23 is fixedly connected to the top of one side of the movable plate 20, and the second contact 23 corresponds to the second contact plate 16. A side wall of the top plate 21 fits with a side wall of the cabinet door 2. Through the push of the spring 22 on the top plate 21, the movable plate 20 can generate a force close to the fixed block 14 when the cabinet door 2 is opened, so that the second contact 23 automatically fits with the second contact plate 16. At this time, when there is current between the fixed block 14 and the cabinet 1, the second display light 15 lights up, which can remind the staff of electric shock. When the second display light 15 is not on, it indicates that the cabinet 1 and the fixed block 14 are not energized, further improving the electric shock protection effect.

[0033] Working principle of the utility model: when in use, when the cabinet door 2 is closed, the handle 7 is turned to make the card plate 11 stuck in the middle of the card slot 5, at this time, the elastic touch ball 12 is in contact with the lock block 4, and the first display light 10 can be lit to judge whether the lock block 4 and the cabinet 1 are charged, so as to remind the staff to avoid electric shock and play a protective role;

[0034] When the handle 7 is turned to control the card plate 11 to move out of the card slot 5, the connecting plate 8 can be moved to the bottom of the lock block 4, so that the first contact 9 is in contact with the first contact plate 13. At this time, whether the cabinet 1 is charged can be judged by whether the first display light 10 is on;

[0035] When the cabinet door 2 is opened, the spring 22 pushes the top plate 21, causing the second contact 23 to fit with the second contact plate 16. At this time, whether the second display light 15 is on can be used to determine whether the fixed block 14 and the cabinet door 2 are energized, thereby reminding the staff to avoid electric shock and playing a protective role.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
