Description

Technical Field

[0001] The utility model relates to the technical field of resistance testers, in particular to a novel insulation resistance tester. Background Art

[0002] An insulation resistance tester is an instrument used to measure and evaluate the insulation performance of electrical equipment. It applies high-voltage direct current to the insulator, measures the generated current and calculates the resistance, thereby determining whether the insulation material meets the specified insulation performance requirements. Insulation resistance testers play an important role in preventive maintenance, fault diagnosis, quality control and safety testing. They can promptly detect early degradation of insulation materials, prevent faults and accidents, and ensure the normal operation of electrical equipment and personnel safety.

Therefore, the existing Chinese utility model patent disclosed by the publication number CN211878073U: an insulation resistance tester, the application has a pin hole at the relative position of the protective shell and the insulation resistance tester, which is convenient for inserting the pin rod into the pin hole, so that the insulation resistance tester can be limited and fixed, so that the insulation resistance tester can better protect the insulation resistance tester from being damaged. However, since the insulation resistance tester mentioned above cannot be stably placed in some use environments, it is impossible to conveniently view the actual value of the insulation resistance tester. In addition, most traditional insulation resistance testers use a single placement method, and the insulation resistance tester cannot be fixed according to actual use needs. Utility Model Content

[0026] like Figure 2-Figure 5 As shown, rotation grooves 12 are provided at the upper positions on both sides of the storage groove 6, and limiting grooves 13 are provided inside the rotation grooves 12. The longitudinal section of the limiting grooves 13 is a regular octagon. A rotation shaft 15 is fixedly installed on one side of the two support rods 7, and a limiting shaft 16 is fixedly installed on one side of the rotation shaft 15. The longitudinal section of the limiting shaft 16 is a regular octagon. The two support rods 7 are rotatably installed in the storage groove 6 through the rotation shaft 15 on one side, and the rotation shaft 15 and the limiting shaft 16 are respectively inserted and installed in the corresponding rotation groove 12 and the limiting groove 13. The rotation shaft 15 on one side of the support rod 7 rotates in the rotation groove 12 to realize the angle adjustment of the support rod 7, and the limiting shaft 16 is inserted and installed in the limiting groove 13 to realize the limited fixing of the rotation angle of the support rod 7.

[0027] like Figure 2 , Figure 6-Figure 8As shown, a guide rail 17 is fixedly installed on the mounting seat 9, and a plurality of tooth grooves 18 are provided on the top of the guide rail 17. Limit plates 19 are fixedly installed on both sides of the guide rail 17. A second connecting shaft 20 is fixedly installed between the two limit plates 19 on both sides of the guide rail 17. A slide groove 22 is provided at the lower end of the splint 10, and the splint 10 located below the slide groove 22 has two plug holes 23. A vertical mounting hole 24 is provided in the splint 10, a screw groove 25 is provided at the upper end of the splint 10, and a mounting groove 26 is provided at the bottom of the screw groove 25, and the cavity between the screw groove 25 and the mounting groove 26 and the mounting hole 24 is connected, and the splint 10 is slidably installed on the guide rail 17 through the slide groove 22, and the plug hole 23 is inserted and installed on the corresponding second connecting shaft 20, and the second connecting shaft 20 between the two splints 10 is sleeved with a first compression Spring 21, a locking tooth is fixedly installed at the bottom of the limit rod 11, a fixing ring 27 is fixedly installed on the outside of the limit rod 11, a stud 28 is inserted and installed on the limit rod 11 above the fixing ring 27, and a pull block 29 is threadedly connected to the upper end of the limit rod 11, the slide groove 22 is inserted and installed in the mounting hole 24, and the stud 28 is threadedly connected in the screw groove 25, and the limit rod 11 located between the fixing ring 27 and the stud 28 is sleeved with a second compression spring 30, and the locking tooth at the lower end of the limit rod 11 is clamped in the corresponding tooth groove 18.

[0028] It should be noted that the utility model is a new type of insulation resistance tester. When the tester body 1 is placed obliquely for use, the two support rods 7 can be pinched relative to each other with one hand, so that the two support rods 7 are deformed by the toughness of their plastic material, and the diameter of the rotating groove 12 is larger than the diameter of the rotating shaft 15. Therefore, the rotating shafts 15 on one side of the two support rods 7 move in the corresponding rotating grooves 12 respectively, and then the rotating shaft 15 drives the limiting shaft 16 to move from the corresponding limiting groove 13 to the rotating groove 12, so that the two support rods 7 can be rotated by a certain angle. When the angle adjustment of the two support rods 7 is completed, the two support rods 7 can be loosened, so that the structural properties of the two support rods 7 can be reset, so that the rotating shaft 15 drives the limiting shaft 16 to be inserted and installed in the corresponding limiting groove 13 again, and then the support rods 7 after the angle adjustment are limited. Subsequently, the tester body 1 can be supported and used by the two support rods 7;

[0029] When testing cables at the same height as the bridge, the two support rods 7 can be rotated in the same way as described above, so that the two support rods 7 cooperate with the first connecting shaft 14 to move the clamping mechanism 8 to the position above the protective shell 5. Then, the two clamping plates 10 can be placed on one side of the object to be clamped, and the two clamping plates 10 can be pressed and moved relative to each other. As a result, the two clamping plates 10 slide on the mounting seat 9 through the sliding grooves 22 at the bottom, and when the clamping plates 10 slide, the teeth at the bottom of the limiting rod 11 are continuously clamped in the corresponding tooth grooves 18. Thereby, the two clamps 10 can be clamped on external pipes and other objects, so as to facilitate the hoisting and use of the tester body 1. When contacting the clamping of the two clamps 10, it is only necessary to lift the pull blocks 29 on the top of the two limit rods 11 respectively, so that the pull blocks 29 drive the limit rods 11 to move upward in the mounting holes 24. At the same time, the locking teeth at the bottom of the limit rods 11 disengage from the tooth grooves 18, and with the help of the force of the first compression spring 21, the clamps 10 are pushed to one side, so that the two clamps 10 move in opposite directions, which facilitates the removal of the tester body 1.
