Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromechanical equipment testing, specifically a testing device for electromechanical equipment installation. Background Technology
[0002] In the field of electromechanical equipment installation, comprehensive and accurate testing of equipment is a key step to ensure its safe and stable operation. Among these tests, insulation testing is particularly important, as it directly relates to whether the equipment can avoid the risk of leakage during use, ensuring the personal safety of operators and the normal operation of the equipment itself.
[0003] Different electromechanical equipment and different locations may require different testing methods. Some are suitable for testing with alligator clips, while others are more suitable for contact testing. Traditional devices often cannot easily switch between these two testing methods and require carrying different testing tools or heads. Changing the testing head is time-consuming, which not only greatly reduces testing efficiency and extends the installation cycle of electromechanical equipment, but may also lead to inaccurate test results due to improper testing methods, creating safety hazards for the subsequent use of the equipment. Therefore, it is necessary to design a testing device for the installation of electromechanical equipment to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a testing device for the installation of electromechanical equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a testing device for the installation of electromechanical equipment, comprising an insulation resistance tester, wherein multiple cables are connected to one side of the insulation resistance tester, and a connecting handle is connected to one end of each cable, and a test rod is slidably installed inside the connecting handle;
[0006] A threaded post is fixedly installed at the lower end of the test rod, and a first internal threaded sleeve and a second internal threaded sleeve are installed in the inner cavity of the insulation resistance tester. Both the first internal threaded sleeve and the second internal threaded sleeve can engage with the threaded post. A detachable alligator clip assembly is installed on the outer side of the upper end of the test rod.
[0007] Preferably, the alligator clip assembly includes an external threaded sleeve, which is welded to the outside of the test rod. A connecting rod is threadedly connected to the outside of the external threaded sleeve, and an alligator clip is fixedly installed on the upper end of the connecting rod.
[0008] Preferably, multiple rotating handles are installed on the outside of the connecting rod.
[0009] Preferably, the plug at one end of the cable is located inside the corresponding socket on the surface of the insulation resistance tester.
[0010] Preferably, the connecting handle is covered with an insulating sheath, and the connecting handle is made of copper.
[0011] Preferably, the second internal threaded sleeve is located above the first internal threaded sleeve.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This testing device for electromechanical equipment installation, by rotating the test rod, separates the threaded column from the first internal threaded sleeve. At this time, pulling the test rod upward causes the threaded column to move upward until it contacts the bottom of the second internal threaded sleeve. Then, twisting the test rod makes the threaded column engage with the second internal threaded sleeve. At this time, the longer test rod extends out of the inner cavity of the connecting handle, increasing the detectable range of the detection contact at the top of the test rod, and making it convenient to extend the detection contact to some gap positions on the surface of the electromechanical equipment for detection, thereby improving the detectable range of the device and ensuring the detection effect.
[0014] 2. When the alligator clip is required for testing, the position of the test rod is changed so that the threaded post engages with the first internal threaded sleeve. By screwing the connecting rod onto the outside of the external threaded sleeve, the alligator clip and the test rod are connected. This allows for easy testing by clamping the alligator clip onto the surface of the equipment to be tested. The switching of testing modes is convenient and improves the versatility of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please refer to Figure 1-3 As shown, this utility model provides a testing device for the installation of electromechanical equipment, including an insulation resistance tester 1. Multiple cables 2 are connected to one side of the insulation resistance tester 1. The plug of one end of the cable 2 is set inside the corresponding socket on the surface of the insulation resistance tester 1. A connecting handle 3 is connected to one end of the cable 2. A test rod 4 is slidably installed inside the connecting handle 3.
[0022] A threaded post 5 is fixedly installed at the lower end of the test rod 4. A first internal threaded sleeve 6 and a second internal threaded sleeve 7 are installed in the inner cavity of the insulation resistance tester 1. The second internal threaded sleeve 7 is located above the first internal threaded sleeve 6. Both the first internal threaded sleeve 6 and the second internal threaded sleeve 7 can engage with the threaded post 5. A detachable alligator clip assembly is installed on the outer side of the upper end of the test rod 4.
[0023] Specifically, depending on the condition of the electromechanical equipment, alligator clips or testing contacts can be used for insulation testing to ensure the safety of the equipment in subsequent use.
[0024] The alligator clip assembly includes an external threaded sleeve 8, which is welded to the outside of the test rod 4. A connecting rod 9 is threadedly connected to the outside of the external threaded sleeve 8. An alligator clip 11 is fixedly installed on the upper end of the connecting rod 9. Multiple rotating handles 10 are installed on the outside of the connecting rod 9. By rotating the rotating handles 10, the connecting rod 9 can be rotated, changing the connection state between the connecting rod 9 and the external threaded sleeve 8, thereby realizing the disassembly and assembly of the alligator clip 11. When using the alligator clip 11 for testing, a passage is formed between the alligator clip 11, the connecting rod 9, the external threaded sleeve 8, and the test rod 4.
[0025] Among them: the connecting handle 3 is covered with an insulating skin and is made of copper. When the test rod 4 is tested by the detection contact at the top, the plug, cable 2 and connecting handle 3 are connected. The connecting handle 3 forms a passage between the threaded post 5 and the test rod 4 through the first internal thread sleeve 6 or the second internal thread sleeve 7, so that normal testing can be carried out.
[0026] Working principle: This utility model is a testing device for the installation of electromechanical equipment. When the detection contact at the top of the test rod 4 is needed for testing, the connecting rod 9 is rotated by rotating the handle 10 until the internal thread of the connecting rod 9 disengages from the external thread of the outer thread sleeve 8. The connecting rod 9, the handle 10, and the alligator clip 11 are then removed from the outside of the test rod 4, exposing the detection contact at the top of the test rod 4 for easy use. When it is necessary to test the insulation performance deep in the gaps of electromechanical equipment, the test rod 4 is rotated to separate the threaded post 5 from the first inner thread sleeve 6. At this time, the test rod 4 is pulled upward to move the threaded post 5 upward until it contacts the bottom of the second inner thread sleeve 7. Then, the test rod 4 is twisted to make the threaded post 5 engage with the second inner thread sleeve 7. At this time, the longer test rod 4 extends out of the inner cavity of the connecting handle 3, increasing the detection range of the detection contact at the top of the test rod 4.
[0027] When the alligator clip 11 is needed for testing, the position of the test rod 4 is changed so that the threaded post 5 engages with the first internal threaded sleeve 6. By screwing the connecting rod 9 onto the outside of the external threaded sleeve 8, the alligator clip 11 is connected to the test rod 4, and it is convenient to perform the testing work by clamping the alligator clip 11 onto the surface of the equipment to be tested.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
