Description

Technical Field

[0001] The utility model relates to the technical field of detection instrument equipment, in particular to a power box detection device with a convenient positioning structure. Background Art

[0002] When testing the electrical equipment in the power box, using a multimeter to test the power box is a crucial electrical safety and maintenance operation. As the core component of power distribution, the performance status of the power box directly affects the stability and safety of the entire circuit system.

When testing the power box, the multimeter can be used to quickly identify whether the output voltage of the power box meets the standard, thereby judging whether its power supply capacity meets the standard. For example, the Chinese utility model patent disclosed by publication number CN218727564U: a portable multimeter, which provides an adjustable bracket and a handheld stabilizing belt, so that the staff can choose whether to place the multimeter on the desktop or use it handheld. When the multimeter is placed on the desktop, the adjustable bracket can make the multimeter be placed vertically for the staff to observe the test data, but by When inspecting electrical equipment in a power box, especially when inspecting large and small power boxes, this type of power box has a certain height. Therefore, when inspecting electrical equipment inside the power box, the inspector generally holds the detection probe, and the multimeter body needs to be placed on an external platform. Therefore, when using the multimeter, the inspector cannot quickly install the multimeter body at a suitable position inside the power box shell, which makes it inconvenient for the inspector to use the probe to contact the connection end of the electrical equipment while checking the detection data on the multimeter body, making data observation inconvenient.

[0027] like Figure 3-Figure 6 As shown, a first ball groove 13 is provided at the top of the storage groove 6, and the storage groove 6 and the first ball groove 13 are provided at the rear side of the multimeter body 1, which can provide conditions for the rotation adjustment and storage of the spline rod 9. A second rotating ball 18 is fixedly installed at the upper end of the spline rod 9, and a damping rubber layer is sprayed on the outer surface of the second rotating ball 18. A truncated cone rod 19 is fixedly installed at the lower end of the spline rod 9. The second rotating ball 18 is rotatably installed in the first ball groove 13, and a through-type is provided in the telescopic rod 8 and the first rotating ball 11. The spline hole 14 has a damping rubber layer sprayed on the inner surface of the spline hole 14, and the outer surface of the first rotating ball 11 is also sprayed with a damping rubber layer. The telescopic rod 8 is inserted and installed on the spline rod 9 through the spline hole 14. The telescopic rod 8 is inserted and installed on the outer side of the spline rod 9 through the spline hole 14, so that the length of the combined structure of the telescopic rod 8 and the spline rod 9 can be adjusted, and the damping rubber layer sprayed on the inner side of the spline hole 14 can be used to limit the adjustment position of the telescopic rod 8 and the spline rod 9 in real time;

[0028] like Figure 5-Figure 7As shown, a second ball groove 15 is provided at the upper end of the ball seat 10, a through hole 16 is provided at the bottom of the second ball groove 15, and a plurality of connecting grooves 17 are provided at the lower end of the ball seat 10 with the through hole 16 as the center.

[0029] It should be noted that the utility model is a power box detection device with a convenient positioning structure. When detecting electrical equipment in a large power box, the telescopic rod 8 can be manually pulled out from the storage slot 6, and the telescopic rod 8 drives the spline rod 9 to rotate and unfold in the first ball slot 13 with the second rotating ball 18 as the axis. Since the outer side of the second rotating ball 18 is sprayed with a damping rubber layer, the real-time limit of the rotation angle of the second rotating ball 18 in the first ball slot 13 can be achieved, thereby adjusting the viewing angle of the multimeter body 1, and then, the telescopic rod 8 is passed through the spline hole. 14 is pulled on the spline rod 9, so that the telescopic rod 8 synchronously drives the first rotating ball 11, the ball seat 10 and the expansion seat 12 to move. When the truncated cone rod 19 is driven to move upward by the spline rod 9, the truncated cone rod 19 uses the structural characteristics of the outer side being wide at the bottom and narrow at the top, so that the wide part of the lower end of the truncated cone rod 19 in the corresponding semicircular table groove 22 gradually moves toward the narrow part of the upper end in the semicircular table groove 22, so that the truncated cone rod 19 gradually and synchronously squeezes the three expansion seats 12 to one side, so that the expansion seat 12 is axially rotated in the ball seat 10 with the rotating shaft 21 in the connecting block 20 as the axis. The lower end of the seat 10 rotates, and then the expansion seat 12 is automatically deflected to one side by the cooperation of the truncated cone rod 19 and the semicircular table groove 22. Therefore, the connecting block 20 at the upper end of the expansion seat 12 rotates in the corresponding connecting groove 17 with the rotating shaft 21 as the axis, thereby solving the problem that the first magnetic blocks 23 on one side of the three expansion seats 12 attract each other and affect the rotation and opening of the expansion seat 12. At this time, the three expansion seats 12 can continue to be manually moved, so that the expansion seat 12 is finally rotated 90 degrees, and one side of the connecting block 20 changes direction and passes through the second magnetic block 24 By adsorbing on the top of the connecting groove 17, the three expansion seats 12 can be unfolded, and then, the telescopic rod 8 can be pulled, so that the telescopic rod 8 moves on the outside of the spline rod 9 through the damping rubber layer on the inner surface and implements limiting. Finally, the three unfolded expansion seats 12 can be adsorbed and fixed at the appropriate position inside the power box shell through the first magnetic block 23 on one side, and the viewing angle of the multimeter body 1 can be further adjusted by rotating the first rotating ball 11 in the second ball groove 15, so that it is convenient for the detection personnel to observe the data displayed on the display screen 2 while operating the probe.
