[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are not intended to limit the present invention or its application or use in any way. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0021] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1 and 2 As shown, the current transformer detection device includes a device clamp 1, with a detection device body 2 detachably mounted inside the device clamp 1. A distance adjustment mechanism 3 is provided on the rear side of the device clamp 1, and a lifting adjustment mechanism 4 is provided on the side of the distance adjustment mechanism 3 opposite to the device clamp 1 to drive its up and down movement adjustment. The device clamp 1 has a C-shaped support frame 11, with an upper pressure groove 12 provided inside the C-shaped support frame 11. The bottom of the upper pressure groove 12 matches the top of the detection device body 2, and a clamping bolt 13 is rotatably mounted on the top of the upper pressure groove 12. The clamping bolt 13 is threadedly connected to the top of the C-shaped support frame 11. In this embodiment, the current transformer detection device is mounted on the wall via the lifting adjustment mechanism 4. The design reduces desktop space usage, freeing up the desktop operating area. More testing equipment can be installed in parallel at each workstation to meet different testing needs. The distance adjustment mechanism 3 allows for a suitable distance between the testing equipment body 2 and the operator, facilitating the reading of test results. The lifting adjustment mechanism 4 adjusts the height of the testing equipment body 2 to accommodate operators of different heights. The testing equipment body 2 is clamped inside the C-shaped support frame 11 via the upper pressure groove 12. Tightening the clamping bolt 13 moves the upper pressure groove 12 up and down, thus releasing or clamping the testing equipment body 2. The testing equipment body 2 is detachable within the C-shaped support frame 11, facilitating maintenance and replacement.

[0023] In some embodiments, the lifting adjustment mechanism 4 has an upper support 41 and a lower support 42 arranged in parallel. A lifting plate 46 is slidably arranged between the upper support 41 and the lower support 42 in the vertical direction. A lead screw 44 is rotatably arranged between the upper support 41 and the lower support 42. The lead screw 44 is threadedly connected to the lifting plate 46. A drive motor 45 is provided on the upper support 41 to drive the lead screw 44 to rotate. The drive motor 45 drives the lead screw 44 to rotate, and the threaded structure between the lead screw 44 and the lifting plate 46 drives the lifting plate 46 to move up and down, thereby realizing the height adjustment of the detection equipment body 2 installed on the lifting plate 46.

[0024] In some embodiments, as a specific implementation where the lifting plate 46 is slidably disposed between the upper support 41 and the lower support 42, two guide rods 43 parallel to the lead screw 44 are symmetrically disposed between the upper support 41 and the lower support 42, and the lifting plate 46 is slidably connected to the guide rods 43.

[0025] In some embodiments, mounting holes are symmetrically provided on both the upper support 41 and the lower support 42; during installation, expansion bolts corresponding to the mounting holes are installed on the wall, and the upper support 41 and the lower support 42 are assembled and fixed on the wall by the expansion bolts.

[0026] In some embodiments, the distance adjustment mechanism 3 has two upper connecting rods 31 symmetrically arranged on both sides of the upper end of the lifting platform 46, and a lower connecting rod 32 parallel to the upper connecting rods 31; a support rod 33 is fixedly arranged between the two lower connecting rods 32, and an electric push rod 34 is hinged to the support rod 33. One end of the electric push rod 34 away from the support rod 33 is hinged to the lifting platform 46. One end of both the upper connecting rod 31 and the lower connecting rod 32 is hinged to the lifting platform 46, and the other end of both the upper connecting rod 31 and the lower connecting rod 32 is hinged to the C-shaped support frame 11. By controlling the extension and retraction of the electric push rod 34, the upper connecting rod 31 and the lower connecting rod 32 can be driven to swing up and down. When the upper connecting rod 31 and the lower connecting rod 32 swing up and down, they can push the detection equipment body 2 to move back and forth. Since the detection equipment body 2 will be driven to move up and down while moving back and forth, after the distance adjustment mechanism 3 is adjusted, the lifting adjustment mechanism 4 is then adjusted to adjust the detection equipment body 2 to the required height.

[0027] In some embodiments, cooling fans 5 are evenly arranged on the back side of the C-shaped support frame 11, and through holes corresponding to the cooling fans 5 are opened on the back side of the C-shaped support frame 11. Since the detection device body 2 installed inside the C-shaped support frame 11 will affect its heat dissipation effect, the cooling fans 5 can accelerate the airflow on the back side of the detection device body 2 and improve the heat dissipation effect.

[0028] In some embodiments, such as Figure 2 and 3As shown, two support bars 14 are provided on the inner side of the C-shaped support frame 11, corresponding to the upper and lower ends of the rear side of the detection equipment body 2, and there is a heat dissipation gap 15 between the two support bars 14. The two support bars 14 support the C-shaped support frame 11 and the detection equipment body 2, so that there is a heat dissipation gap 15 between the C-shaped support frame 11 and the detection equipment body 2. After the cooling fan 5 is started, it can generate airflow on the back side of the detection equipment body 2, thereby improving the heat dissipation effect.

[0029] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0030] The embodiments described above only illustrate some implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
