Description

TECHNICAL FIELD

Due to the limitation of the instrument, it can only be carried by a packaging bag in daily life. The connecting lines are easily entangled and knotted, which is inconvenient to use. At the same time, due to long-term exposure to the external environment, the connecting line surface is easily contaminated with a large amount of dust and pollutants, which affects the use effect and service life of the connecting line.

[0016] (III) Beneficial Effects

[0017] This invention provides a portable insulation resistance tester and its usage method. It offers the following advantages:

[0018] (1) By setting a rotating block and a driving rod, the two driving rods can be driven to rotate simultaneously through the internal mechanism of the driving box. In turn, the driving rod drives the rotating block to rotate, so that the placement cavity is exposed to the outside of the fixed box. At this time, the test needle can be taken out. At the same time, when storing, the connecting wire can be completely pulled back into the case by the winding reel connected by the coil spring, which facilitates the storage of the connecting wire and makes it more convenient to take out, place and carry.

[0019] (2) By setting up a rotating drum and a guide rod, when the drive rod rotates to lift or retract the rotating block, the rotation can be transmitted to the rotating drum through the transmission rod and the guide rod, thereby causing the rotating drum to rotate. This allows the connecting wire to be pulled outward or retracted inward while the surface of the connecting wire is being scraped and cleaned in all directions. This prevents a large amount of dust from the external environment from continuously adhering to the surface of the connecting wire, which would cause the insulation layer on the surface of the connecting wire to be corroded, thus improving the safety and overall cleanliness of the connecting wire.

Guide wheels 14 are fixedly connected to the side walls of the power block 13 near the two winding reels 4. One end of the connecting wire 12 is fixedly connected to the power block 13, and the other end of the connecting wire 12 passes through the guide wheel 14, through the partition 2 and the rotating block 9, and is connected to the test needles 11. Two rotating rings 15 are fixedly connected to the inner bottom surface of the carrying case 1. A rotating cylinder 16 is rotatably connected to the inner side of the rotating rings 15. Multiple cleaning brushes 17 are fixedly connected to the inner side wall of the rotating cylinder 16. The two connecting wires 12 are respectively set through the two rotating cylinders 16. Both ends of the drive rod 8 pass through the side wall of the fixed box 7 and are rotatably connected to the inner side wall of the carrying case 1. The outer side wall of the carrying case 1 is fixed. A drive box 20 is connected. The ends of two drive rods 8 near the drive box 20 rotatably penetrate the side wall of the carrying case 1 and are rotatably connected to the inner side wall of the drive box 20. A horizontally arranged worm gear 21 is provided inside the drive box 20. Worm wheels 22 are fixedly sleeved on the two drive rods 8 at positions corresponding to the worm gear 21, and the worm gear 21 and worm wheels 22 mesh with each other. Two horizontally arranged transmission rods 25 are rotatably connected to the inner side wall of the carrying case 1. A transmission box 24 is fixedly connected to the side wall of the carrying case 1 away from the drive box 20 at positions corresponding to the two drive rods 8. The ends of the drive rods 8 and 25 near the transmission box 24 rotatably penetrate the side wall of the carrying case 1 and are rotatably connected to the inner side wall of the transmission box 24. A pulley 26 is fixedly sleeved on both the drive rods 8 and 25. Two pulleys 26 inside a transmission box 24 are driven by the same belt. A guide rod 27 is rotatably connected through the partition 2. Bevel gears 28 are fixedly connected to the upper and lower ends of the guide rod 27. Engaging wheels 29 are fixedly sleeved on the rotating drum 16 and the transmission rod 25 at the positions corresponding to the guide rod 27. The bevel gears 28 at the upper and lower ends of the guide rod 27 respectively mesh with the two engaging wheels 29. Restriction rings 18 are provided on both sides of the rotating drum 16. The restriction rings 18 are fixedly connected to the bottom surface of the lifting box 1. Multiple balls 19 are rotatably connected to the inner side wall of the restriction rings 18. The restriction rings 18 are sleeved on the outside of the connecting line 12. A motor 23 is fixedly installed on the outer side wall of the drive box 20. The output end of the motor 23 rotatably passes through the side wall of the drive box 20 and is fixedly connected to the worm gear 21 on the same axis.

[0026] Working principle: When the test probe 11 needs to be retrieved, the output end of the start motor 23 rotates in the forward direction. At this time, the output end of the start motor 23 drives the worm gear 21 to rotate. The rotation of the worm gear 21 is transmitted to the two drive rods 8 through the worm wheel 22. At this time, the drive rods 8 drive the rotating blocks 9 to rotate, causing the rotating blocks 9 on both sides to lift upward. When the rotating blocks 9 are fully lifted, the upper opening of the placement cavity 10 can be vertically exposed, thus facilitating the retrieval of the test probe 11. After the test probe 11 is placed, the output end of the start motor 23 rotates in the forward direction. When the end rotates in the opposite direction, the drive rod 8 rotates in the opposite direction, causing the rotating block 9 to be retracted into the fixed box 7. The coil spring 6 at the lower end of the winding reel 4 drives the winding reel 4 to rotate. At this time, the connecting wire 12 is retracted onto the winding reel 4. Simultaneously, the drive rod 8 drives the transmission rod 25 to rotate through the belt pulley 26. The rotation of the transmission rod 25 is transmitted to the rotating drum 16 through the meshing wheel 29, bevel gear 28, and guide rod 27. At this time, the rotation of the rotating drum 16 can scrape and clean the connecting wire 12 on the retracted winding reel 4 through the cleaning brush 17.

[0027] In summary, this portable insulation resistance tester and its usage method, by setting up a rotating block and a drive rod, allows two drive rods to rotate simultaneously through the internal mechanism of the drive box. This, in turn, drives the rotating block to rotate, exposing the placement cavity to the outside of the fixed box, allowing the test probe to be retrieved. Simultaneously, during storage, the rotating shaft and winding reel, connected by a spring, allow the connecting wire to be completely pulled back into the carrying case, facilitating wire storage and making retrieval, placement, and carrying more convenient. Furthermore, when the drive rod rotates to lift or retract the rotating block, the rotation is transmitted to the rotating drum via the transmission rod and guide rod, causing the drum to rotate. This allows the connecting wire to be pulled outwards or retracted inwards, simultaneously performing a comprehensive scraping and cleaning of the connecting wire surface. This prevents the continuous adhesion of large amounts of dust from the external environment to the connecting wire surface, which could corrode the insulation layer and improve the safety and overall cleanliness of the connecting wire.
