[0004] The testing device features foldable wheels for easy carrying, but the wheels are in contact with the ground, causing debris to adhere to them. This debris can soil a user's clothes when carrying the device. Furthermore, the device lacks support at the bottom when folded, making it inconvenient for temporary placement.

[0005] Therefore, in order to solve the above problems, a current detection box for electricity information acquisition equipment is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a current detection box for an electricity information collection device, in order to solve the problem mentioned in the background art that the detection device in the prior art can be conveniently carried by the user by setting up foldable and storage wheels. However, when the device is in use, the wheels need to contact the ground, so debris on the ground will stick to the wheels. When the user carries the device, the debris will soil the user's clothes. In addition, after the wheels are folded, the bottom of the device has no support, which is not convenient for temporary placement of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a current detection box for an electricity information acquisition device, comprising: a base plate, wherein a shielding box is installed on the top surface of the base plate;

[0008] A movable structure is installed on the bottom surface of the base plate. The movable structure includes a fixed block, which is fixedly installed at the four corners of the bottom surface of the base plate. A movable groove is provided on the side wall of the fixed block. A rotating shaft is rotatably installed on the inner side of the movable groove. An unfolding hole is provided on the top surface of the rotating shaft. A folding hole is provided on the side wall of the rotating shaft. A wheel cover is fixedly connected to the bottom end of the rotating shaft. A roller is rotatably installed on the inner side of the wheel cover. A positioning bolt is threadedly connected to the top surface of the base plate.

[0009] A backing structure is installed on the side wall of the base plate. The backing structure includes a side plate, which is fixedly installed on the right side wall of the base plate.

[0010] Preferably, a storage groove is provided on the right side wall of the side panel, a soft pad is adhered to the right side wall of the side panel, a carrying strap is fixedly connected to the inner side of the storage groove, a baffle is rotatably connected to the right side wall of the side panel, and a magnetic block is installed inside the surface of the baffle.

[0011] Preferably, the bottom end of the positioning bolt is inserted into the interior of the unfolding hole, the positioning bolt and the unfolding hole are matched, and the unfolding hole and the folding hole are the same size.

[0012] Preferably, both the wheel cover and the roller are vertically arranged, and the bottom end of the fixing block is located on one side of the outer wall of the wheel cover.

[0013] Preferably, the storage slots are provided in two sets, and the soft pad is located between the two sets of storage slots.

[0014] Preferably, the magnetic block is magnetically connected to the side plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by providing a wheel cover, the wheel cover can cover the outside of the roller when the roller is stored and folded, preventing the roller from directly contacting the user's clothing. In addition, the bottom of the fixing block is lower than the bottom surface of the wheel cover, so that after the roller is stored, it can be supported on the placement surface by the fixing block, ensuring the stability of the device and making it easy to use.

[0016] This invention features a movable structure. When moving the device on flat ground, pushing the side plate allows the rollers to roll on the ground, facilitating easy repositioning of the shielding box. On uneven ground, rotating the positioning bolt unscrewing it from the unfolded hole releases the rotating shaft from its fixation within the movable groove. Flipping the wheel cover allows the rotating shaft to rotate within the movable groove, causing the rollers to retract inwards under the base plate. At this point, the folding hole aligns with the positioning bolt. Rotating the positioning bolt again screws its bottom end into the folding hole, allowing the rotating shaft to retract within the movable groove. The angle is fixed, keeping the rollers in a retracted state. The wheel cover can cover the outside of the rollers, preventing the rollers from directly contacting the user's clothes and soiling them. Pulling the baffle releases the magnetic attraction between the magnet and the side plate, making it easier to expose the inside of the storage slot and remove the shoulder straps from inside the storage slot for easy transfer of the carrying device. The bottom of the fixing block is lower than the bottom surface of the wheel cover. During use, the fixing block can support the device from below, ensuring the stability of the device and making it easy to use. The shoulder straps can also be stored inside the storage slot, preventing them from being scattered and affecting the appearance, thus improving the practicality of the device.

[0026] A current detection box for an electricity information collection device includes: a base plate 1, and a shielding box 11 installed on the top surface of the base plate 1;

[0027] A movable structure 2 is installed on the bottom surface of the base plate 1. The movable structure 2 includes a fixed block 21, which is fixedly installed at the four corners of the bottom surface of the base plate 1. A movable groove 22 is provided on the side wall of the fixed block 21. A rotating shaft 23 is rotatably installed on the inner side of the movable groove 22. An unfolding hole 24 is provided on the top surface of the rotating shaft 23. A folding hole 25 is provided on the side wall of the rotating shaft 23. A wheel cover 26 is fixedly connected to the bottom end of the rotating shaft 23. A roller 27 is rotatably installed on the inner side of the wheel cover 26. A positioning bolt 28 is threadedly connected to the top surface of the base plate 1. When the roller 27 is folded and stored, the wheel cover 26 can cover the outside of the roller 27 to prevent the roller 27 from directly contacting the user's clothing. Furthermore, the bottom end of the fixed block 21 is lower than the bottom surface of the wheel cover 26. After the roller 27 is folded and stored, it can be supported on the placement surface by the fixed block 21 to ensure the stability of the device and facilitate its use.

[0028] A back support structure 3 is installed on the side wall of the base plate 1. The back support structure 3 includes a side plate 31, which is fixedly installed on the right side wall of the base plate 1.

[0029] Furthermore, a storage groove 32 is provided on the right side wall of the side panel 31, a soft pad 33 is adhered to the right side wall of the side panel 31, a shoulder strap 34 is fixedly connected to the inside of the storage groove 32, and a baffle 35 is rotatably connected to the right side wall of the side panel 31. A magnet 36 is installed inside the surface of the baffle 35, and the shoulder strap 34 can be stored inside the storage groove 32 to prevent the shoulder strap 34 from being scattered and affecting the appearance.

[0030] Furthermore, the bottom end of the positioning bolt 28 is inserted into the interior of the unfolding hole 24. The positioning bolt 28 and the unfolding hole 24 are matched. The unfolding hole 24 and the folding hole 25 are the same size. The positioning bolt 28 is inserted into the interior of the unfolding hole 24 and the folding hole 25, which can fix the roller 27 in the unfolded and retracted states respectively, to prevent the roller 27 from becoming loose and affecting the user experience.

[0031] Furthermore, both the wheel cover 26 and the roller 27 are vertically arranged. The bottom end of the fixing block 21 is located on one side of the outer wall of the wheel cover 26. When the roller 27 is folded, the bottom end of the fixing block 21 is lower than the bottom surface of the wheel cover 26. When placing the device, the fixing block 21 can be supported on the mounting surface to ensure installation stability.

[0032] Furthermore, the storage slots 32 are provided in two sets, and the soft pad 33 is located between the two sets of storage slots 32. The soft pad 33 can ensure the comfort of carrying the device and improve the user experience of the device.

[0033] Furthermore, the magnetic block 36 is magnetically connected to the side plate 31, and the baffle 35 can be fixed by connecting the magnetic block 36 to the side plate 31 to cover the shoulder strap 34 in the storage slot 32 and ensure the storage effect.

[0034] Working principle: When moving the device on flat ground, pushing the side plate 31 allows the rollers 27 to roll on the ground, enabling the shielding box 11 to be moved easily. When the ground is uneven, rotating the positioning bolt 28 unscrews it from the unfolding hole 24, releasing the fixing of the rotating shaft 23 inside the movable groove 22. Flipping the wheel cover 26 causes the rotating shaft 23 to rotate inside the movable groove 22, allowing the rollers 27 to be retracted inwards under the base plate 1. At this time, the folding hole 25 is aligned with the positioning bolt 28. Rotating the positioning bolt 28 allows the bottom end of the positioning bolt 28 to be screwed into the inside of the folding hole 25, which can fix the angle of the rotating shaft 23 inside the movable groove 22, so that the roller 27 is kept in the stored state. The wheel cover 26 can cover the outside of the roller 27 to prevent the roller 27 from directly contacting the user's clothes and contaminating the clothes. Pulling the baffle 35 releases the magnetic attraction between the magnet 36 and the side plate 31, making it easier to expose the inside of the storage groove 32, so that the carrying strap 34 can be taken out from the inside of the storage groove 32, making it easier to transfer the carrying device.

[0035] The bottom of the fixing block 21 is lower than the bottom surface of the wheel cover 26. When in use, the fixing block 21 can support the device from below, which can ensure the stability of the device and make it easy to use. In addition, the shoulder strap 34 can be stored inside the storage slot 32, which prevents the shoulder strap 34 from being scattered and affecting the appearance, thus improving the practicality of the device.
