[0022] Refer to Figures 1-4 A kind of multi-core electric energy meter harmonic test device, including two boxes 1, box 1 is the box type component that is set in half, and for the structure for receiving and protecting device in prior art, hinge 2 is the component for the opening and closing of two boxes 1 in prior art, and is fixed at the junction of two boxes 1, cavity is the structure for storing device in box 1.

[0023] The box body 1 is provided with a slot 4, which is a groove in the prior art used for interlocking of box-shaped components. A buckle body 3 is fixedly installed on the box body 1. The buckle body 3 is a component in the prior art used for hinge locking. It usually cooperates with the groove to achieve the locking and fastening function. The buckle body 3 is compatible with the slot 4.

[0024] The housing 1 is equipped with multiple first rollers 9. The first rollers 9 are made of stainless steel and are covered with rubber rings to reduce noise from rolling on the ground. The outer wall of the housing 1 has grooves, which are the grooves on which the first rollers 9 are arranged. Multiple first fixing strips 7 are provided in the grooves. The first fixing strips 7 are rectangular structures used to fix the wheel assembly structure in the prior art. The surface of the first fixing strips 7 has circular grooves that connect to the first rollers 9. The first rollers 9 are rotatably connected to the first fixing strips 7 by fixing members 8. The fixing members 8 are fixedly connected to the circular grooves by welding, and the fixing members 8 are fastened to the first rollers 9 by rivets.

[0025] The box 1 is provided with multiple second rollers 11. The second rollers 11 are smaller than the first rollers 9. They are used to balance the transportation effect of the other box 1, thereby ensuring the balance of the box 1 during transportation. A groove is provided on one side of the box 1. Multiple second fixing strips 10 are provided in the groove. The second fixing strips 10 have the same structure as the first fixing strip 7 mentioned above, and are used to fix the second rollers 11. The second rollers 11 are rotatably connected to the second fixing strips 10 and are fixedly connected by connecting rods.

[0026] Two enclosures 1 are equipped with a first protective sheet 5, which is made of acrylic sheet using existing technology and has high transparency, making it easy for workers to clean debris and stains on the first protective sheet 5. At the same time, the first protective sheet 5 has waterproof and heat insulation functions, and the different materials used in the existing enclosures 1 help to improve the service life of the enclosures 1. The first protective sheet 5 is fixedly connected to the enclosure 1 by a metal sheet and four rivets. Holes are made at the four corners of the metal sheet, and one end of each of the four rivets is passed through the metal sheet and fixedly connected to the outer wall of the enclosure 1. The metal sheet is fixed by screws that penetrate the first protective sheet 5. Before penetration, the screws need to be coated with glue to facilitate adhesion between the screws and the acrylic sheet. The protruding screws also need to be sawed off with a tool to ensure the flatness of the first protective sheet 5.

[0027] The housing 1 is equipped with a second protective sheet 6 for protecting the device. The second protective sheet 6 is made of sponge, which is used in the prior art. It is mainly used to protect the device so that it will not be bumped by the road surface during transportation, causing the outer wall of the device to collide with the inner wall of the housing 1. At the same time, the sponge can effectively protect the corners of the device, thereby achieving a reasonable protection effect. The second protective sheet 6 is fixedly connected to the inner wall of the cavity. The second protective sheet 6 is fixed to the inner wall of the cavity by buckles and two screws.

[0028] The working principle of this utility model is as follows:

[0029] Place the electricity meter device to be tested into the cavity of one of the boxes 1. Ensure the device is placed securely to prevent movement or collision during transportation. Close the lid of box 1 and close the two boxes 1 using hinge 2. At this time, the latch 3 and the latch 4 cooperate to lock the box 1, ensuring that the device will not be accidentally opened during transportation. Adjust the positions of the first roller 9 and the second roller 11 as needed to facilitate the movement and transportation of box 1. The first roller 9 is used to reduce noise from rolling on the ground, while the second roller 11 is used to balance the transportation of the other box 1, ensuring the balance of box 1 during transportation. During transportation, if necessary, the box 1 can be further protected by a first protective plate 5, which is fixed by a metal sheet and four rivets. The first protective plate 5 has high permeability, which is beneficial for workers to clean debris and stains. It also has waterproof and heat insulation functions, which helps to improve the service life of box 1. After arriving at the destination, open the lid of box 1 and take out the electricity meter device for testing. During testing, the second protective plate 6 effectively protects the device from road bumps and prevents the outer wall of the device from colliding with the inner wall of the housing 1. The energy meter device is then placed back into the cavity of the housing 1, the cover is closed, and the locking mechanism is engaged. The entire device is then transported back to its original location or the next testing site.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
