Description

Technical Field

[0001] The utility model belongs to the technical field of resistance testers, and particularly relates to an insulation resistance tester. Background Art

[0002] A resistance tester is an instrument for measuring the conductivity of an object. Resistance testers are widely used in occasions such as electrical safety inspections and the completion inspections of grounding projects. There are many types of resistance testers, including grounding resistance testers, insulation resistance testers, DC resistance measuring instruments, surface resistance testers, and loop resistance testers.

[0003] The following problems exist when using the existing insulation resistance testers on the market:

[0004] 1. When the traditional insulation resistance tester is applied, since the test pen jack of the test instrument is exposed, dust and dirt are easily accumulated inside the pen jack when it is not in use, which will affect the test data of the staff and cause inaccurate measurement of the tester.

[0005] 2. When most insulation resistance testers are applied, when using the tester, situations such as high on the wall or testing the internal components of an object may be encountered. At this time, it is inconvenient for the staff to hold the tester for operation, making the staff time-consuming and laborious during operation. Content of the Utility Model

[0006] The purpose of the utility model is to provide an insulation resistance tester to solve the technical problems proposed in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: An insulation resistance tester includes an instrument. A fixing plate is fixedly connected to the outside of the instrument. A card slot is opened at the top of the fixing plate. A card block is inserted into the card slot. A connecting plate is fixedly connected to the top of the card block. The connecting plate is connected to a cover plate through a rotating shaft. An adhesive block is installed at the bottom of the cover plate. The adhesive block is inserted into the pen jack inside. The pen jack is opened at the top of the instrument.

[0008] Preferably, a sliding groove is opened on the surface of the instrument. A sliding block is inserted into the sliding groove. The sliding block is fixedly connected to the surface of the side plate. The side plate is fixedly connected to the bottom plate on the side. A fixing block is installed at the bottom of the bottom plate. A strong magnet is inlaid inside the fixing block. A suction cup is installed at the bottom of the bottom plate. A baffle is installed on the side of the bottom plate.

[0009] Preferably, a round hole is opened on the surface of the fixing plate. A threaded rod is inserted into the round hole. The bottom of the threaded rod is threadedly connected to a threaded hole. The threaded hole is opened on the surface of the card block.

[0010] Preferably, a pinch block is installed on the top of the cover plate. The shape of the pinch block is rectangular.

[0011] Preferably, an adjustment knob is installed on the top of the instrument, and a screen is provided on the surface of the instrument.

[0012] Preferably, a knob is installed on the top of the threaded rod, and the shape of the knob is circular.

In this way, when the instrument 1 is not in use, the cover plate 2 can be flipped through the rotating shaft so that the rubber block 7 at its bottom is inserted into the pen lead jack 6, which can prevent dust and dirt from accumulating inside the pen lead jack 6. And when the rubber block 7 is worn after long-term use, the card block 22 can be pulled out from the card slot 15 to remove and replace the cover plate 2 and the rubber block 7, so as to maintain the dust-proof effect on the pen lead jack 6. In this way, the pen lead jack 6 can be covered to prevent dust when the tester is idle, which will not affect the test data when the subsequent staff uses it, and enables the tester to maintain an accurate measurement effect.

[0031] A chute 20 is provided on the surface of the instrument 1. A slider 12 is inserted into the chute 20. The slider 12 is fixedly connected to the surface of the side plate 5.

A suction cup 10 is installed at the bottom of the bottom plate 11. A baffle 4 is installed on the side of the bottom plate 11. In this way, when testing components inside an object at a high position on the wall, the suction cup 10 at the bottom of the floor can be used to adsorb the bottom plate 11 at a flat position near the component to be detected, or the bottom plate 11 can be adsorbed by magnetic attraction using the strong magnet 9 according to the surrounding objects. Then, the slider 12 is inserted into the chute 20 on the surface of the instrument 1, and the instrument 1 is placed between the side plate 5 and the baffle 4. In this way, the staff does not need to hold the tester for operation, which saves time and effort for the staff during operation and is very convenient.

[0032] A round hole 14 is provided on the surface of the fixing plate 13. A threaded rod 16 is inserted into the round hole 14. The bottom of the threaded rod 16 is threadedly connected to a threaded hole 23. The threaded hole 23 is provided on the surface of the block 22. Through the structure of the threaded rod 16 and the threaded hole 23, it is convenient for the user to fix the connecting plate 21 on the fixing plate 13.
