Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A DC switch device for electricity use that is convenient for wiring: including a cabinet body 1, a DC switch body 11 is arranged on the surface of the cabinet body 1, and a deployment mechanism is arranged on the surface of the cabinet body 1. The deployment mechanism includes a movable rod 2, the movable rod 2 is slidably connected to the surface of the cabinet body 1, a connecting plate 21 is fixedly connected to the surface of the movable rod 2, a limiting rod 22 is fixedly connected to the surface of the cabinet body 1, a side plate 23 is fixedly connected to the surface of the connecting plate 21, a fixing nut 24 is fixedly connected to the surface of the cabinet body 1, a limiting bolt 25 is threadedly connected to the surface of the fixing nut 24, and a cabinet door 26 is rotatably connected to the surface of the side plate 23. Its deployment mechanism can deploy the side plate 23 from both sides of the cabinet body 1, thereby expanding the space inside the cabinet body 1 and facilitating wiring the DC switch body 11 on the cabinet body 1.

[0024] Furthermore, a lifting mechanism is arranged at the bottom of the cabinet body 1. The lifting mechanism includes a base 3, the base 3 is fixedly connected to the bottom of the cabinet body 1, a support plate 31 is fixedly connected to the surface of the base 3, a motor 32 is fixedly connected to the surface of the support plate 31, a lead screw 33 is fixedly connected to the output shaft of the motor 32, a movable nut 34 is fixedly connected to the surface of the lead screw 33, a guide rod 35 is fixedly connected to the surface of the cabinet body 1, and a movable block 36 is slidably connected to the surface of the guide rod 35. Since the wiring height requirements of each wiring master are different, by changing the height of the cabinet body 1 and the DC switch body 11 through the lifting mechanism, the adaptability of wiring the DC switch body 11 can be improved, and the wiring efficiency of the wiring master can be improved.

[0025] Further, a guiding hole is provided on the back of the cabinet body 1. The movable rod 2 slides on the guiding hole of the cabinet body 1. Two groups of limiting rods 22 are provided and fixedly connected to both ends of the guiding hole of the cabinet body 1. The movable rod 2 drives the connecting plate 21 to slide on the guiding hole of the cabinet body 1. The cabinet body 1 maintains a connection relationship with the side plate 23 through the connecting plate 21.

[0026] Further, a guiding hole is provided on the surface of the limiting rod 22. The connecting plate 21 slides on the guiding hole of the limiting rod 22. The limiting rod 22 prevents the movable rod 2 from sliding out of the guiding hole of the cabinet body 1. The side plate 23 slides on both sides of the cabinet body 1 through the connecting plate 21, thereby expanding the space inside the cabinet body 1. Two groups of side plates 23 are provided. The cabinet door 26 is rotatably connected to one group of side plates 23, and a locking mechanism for the cabinet door 26 is provided on the other group of side plates 23 to fixedly connect the cabinet door 26 to both groups of side plates 23 simultaneously. When the side plate 23 is unfolded, the cabinet door 26 cannot be fixed to the side plate 23 anymore.

[0027] Further, four groups of fixing nuts 24 are provided. Circular holes are provided on the surface of the side plate 23. The limiting bolts 25 pass through the circular holes of the side plate 23 and are threadedly connected to the fixing nuts 24. The fixing nuts 24 and the limiting bolts 25 limit the position of the side plate 23 on the cabinet body 1, thereby completing the fixation of the side plate 23 on both sides of the cabinet body 1.

[0028] Further, the lead screw 33 rotates on the support plate 31 through the output shaft of the motor 32. The movable nut 34 slides up and down on the surface of the support plate 31 by rotating the lead screw 33. The lead screw 33 and the guide rod 35 are parallel to each other and have the same height. One side of the movable nut 34 and the movable block 36 are in contact connection with the surface of the support plate 31.

[0029] Further, the movable nut 34 and the movable block 36 are fixedly connected to the bottom of the cabinet body 1. The guide rod 35 guides the sliding of the cabinet body 1 through the movable block 36, ensuring the stability of the lifting of the cabinet body 1 on the support plate 31. The lead screw 33 drives the cabinet body 1 to slide up and down on the support plate 31 through the movable nut 34, thereby changing the horizontal height of the DC switch body 11, facilitating wiring by different technicians.

[0030] Working principle: Rotate the limiting bolt 25 on the fixing nut 24 on the side plate 23 so that the limiting bolt 25 is removed from the guiding hole of the side plate 23. The side plate 23 slides outward on both sides of the cabinet body 1 through the connecting plate 21 until the movable rod 2 slides on the guiding hole of the cabinet body 1 and contacts and connects with the limiting rod 22. At this time, the side plate 23 cannot continue to slide on both sides of the cabinet body 1. The movement of the position of the side plate 23 expands the space inside the cabinet body 1, enabling the wiring technician to have more space for operation, reducing the wiring difficulty, and improving the wiring efficiency.

[0031] The output shaft of the motor 32 drives the lead screw 33 to rotate. The lead screw 33 drives the movable nut 34 to slide up and down on the support plate 31 through rotation. The movable nut 34 drives the cabinet body 1 to slide up and down on the support plate 31. The movable block 36 slides on the guide rod 35 to maintain the stability of the lifting of the cabinet body 1. The cabinet body 1 changes the horizontal height of the DC switch body 11, and can meet the wiring heights of different wiring workers for the DC switch body 11.
