Description

Technical Field

[0001] This utility model relates to the field of power maintenance, and more specifically, to a portable testing instrument for power maintenance. Background Technology

[0002] Power maintenance is mainly divided into the following parts: power generation, power supply, substation, and distribution. Each part is handled by specialized personnel who are mainly responsible for daily equipment installation and maintenance, troubleshooting, and line inspection. It is a profession that involves the maintenance of the power grid and its auxiliary equipment, and requires a high level of expertise.

[0003] In existing technologies, power testing instruments are usually installed in a protective enclosure with handles for easy carrying. However, in actual use, due to the demands of complex outdoor working conditions, multi-functional integrated design, and the need for high protection and stability, the testing instruments are generally quite heavy. Carrying them with one hand for extended periods can easily lead to hand fatigue. Furthermore, when using a ladder to climb to higher places, it is difficult to operate with one hand and carries the risk of falling. Therefore, we propose a portable testing instrument for power maintenance. Utility Model Content

When there is a lot of equipment or when climbing a ladder is required, the shoulder strap 6 can be pulled out and used in conjunction with the connecting buckle 7 and the L-shaped buckle 8 to carry the tester 1 on the body. This can effectively reduce hand pain and improve safety during ladder climbing.

[0030] Example 2

[0031] The portable testing instrument for power maintenance provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the unlocking assembly includes a rotating plate 12 that provides rotation function. The rotating plate 12 is fixedly connected to one end of the displacement rod 11 located outside the winding box 3. A knob 13 for operation is rotatably connected to the surface of the rotating plate 12. A mounting ring 14 for structural installation is fixedly connected to the outer surface of the displacement rod 11. Teeth 10 are also fixedly connected to the left side surface of the mounting ring 14. Two sets of teeth 10 mesh with each other. A spring 16 for providing reset power is fixedly connected to the right side surface of the mounting ring 14. The end of the spring 16 is fixedly connected to the inner wall of the winding box 3. A reset plate 17 is fixedly sleeved on the outer surface of the rotating rod 4.

[0033] The usage process of the portable testing instrument for power maintenance provided by this utility model is as follows:

[0034] When the tester 1 is pulled normally, the locking bolt 23 can be loosened to disengage it from the locking hole 24. Then, the grip rod 22 can be pulled outwards, which will drive the tension rod 21 to move. After the tension rod 21 extends to a suitable length, it can be locked again by the locking bolt 23. After locking, the tester 1 can be erected and moved with the motion wheel 15. At the same time, when climbing ladders or when there is a lot of equipment, the protective cover 19 can be opened, and then the knob 13 can be pulled. The knob 13 will drive the rotating plate 12 and the displacement rod 11 to move. When the displacement rod 11 moves... The installation ring 14 will move synchronously, and the two sets of teeth 10 will separate after the installation ring 14 moves. At this time, the rotating rod 4 will be unlocked. At the same time, the spring 16 will be compressed when the installation ring 14 moves, in preparation for subsequent reset. Then, pull the connecting buckle 7 outward. After pulling out to a suitable length, fasten the connecting buckle 7 on the L-shaped buckle 8 and release the knob 13. Under the action of the spring 16, the installation ring 14 will reset, and the two sets of teeth 10 will re-engage to complete the lock. Then, put the protective cover 19 back on. At this time, the tester 1 can be carried on the body with the help of the two shoulder straps 6.
