Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical parameter tester fixing technology, specifically an improved structure of an electrical parameter tester fixing device. Background Technology
[0002] The electrical parameter tester is specifically designed to detect the leakage current of gapless zinc oxide surge arresters used in 10kV and below power systems under DC reference voltages U1mA and 0.75U1mA. It adopts an automatic control principle to perform precise closed-loop adjustment of the 1mA current and 0.75 times the DC reference voltage. The measurement process is controlled by a microcomputer. With just the press of a button, the leakage current of the zinc oxide surge arrester at 1mA DC reference voltage and 0.75 times the DC reference voltage can be automatically measured. The entire process takes only 15 seconds, making it very suitable for batch measurements.
[0003] According to the intelligent electrical parameter tester fixing device disclosed in Chinese Patent Publication No. CN216350852U, the device includes two L-shaped fixing frames. A connecting rod is fixedly connected to the inner side of one L-shaped fixing frame, and a sliding plate is fixedly connected to one side of the connecting rod. A movable rod is slidably connected to the inner side of the sliding plate. A fixing mechanism is installed in the inner cavity of the other L-shaped fixing frame. The fixing mechanism includes a mounting box and an electromagnet installed inside the mounting box. The electromagnet and the movable rod are directly opposite each other. A connecting spring is fixedly connected to one side of the mounting box. In the above solution, by utilizing the cooperation between the connecting mechanism and the fixing mechanism, the movable rod can be attracted by the electromagnet to achieve the fixing effect in actual use. The magnitude of the magnetic force generated by the electromagnet can be controlled by the magnitude of the current, ensuring the fixing effect while allowing for easy disassembly by simply disconnecting the current. This results in better assembly and disassembly.
[0004] However, the existing technology does not have a corresponding positioning mechanism when the electrical parameter tester is placed on the workbench. It is simply placed on the workbench. When the workbench shakes or touches the electrical parameter tester, the tester is prone to shaking and displacement, or even falling off the workbench, which affects the test data. Utility Model Content
[0005] The purpose of this utility model is to provide an improved structure for fixing an electrical parameter tester, so as to solve the problem mentioned in the background art that when the electrical parameter tester is placed on the workbench, there is no corresponding positioning mechanism. It is simply placed on the workbench. When the workbench shakes or touches the electrical parameter tester, it is easy for the electrical parameter tester to shake and shift, or even fall off the workbench, resulting in problems affecting the test data.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] An improved structure for fixing an electrical parameter tester includes a base, a fixing mechanism on the outside of the base, and an installation mechanism on the outside of the base.
[0008] The fixing mechanism includes a sliding groove and a connecting groove. An adjustment groove is provided on the inner side of the sliding groove. A rotating rod is rotatably connected to the inner side of the adjustment groove. A gear is fixedly connected to the outer side of the rotating rod. A toothed plate meshes with the top of the gear. A connecting seat is rotatably connected to one end of the toothed plate. A threaded rod is rotatably connected to the inner side of the connecting seat. An abutment block is fixedly connected to one end of the threaded rod. A suction cup is installed on the inner side of the connecting groove.
[0009] Preferably, multiple sliding grooves are provided, and all of the sliding grooves and connecting grooves are provided on the outside of the base.
[0010] Preferably, the toothed plate is T-shaped, and one end of the toothed plate is slidably connected to the inner side of the groove.
[0011] Preferably, multiple suction cups are provided, and the multiple suction cups are arranged in a linear array.
[0012] Preferably, the mounting mechanism includes a mounting groove, a bidirectional lead screw is rotatably connected to the inner side of the mounting groove, a moving block is threaded to the outer side of the bidirectional lead screw, and a positioning plate is fixedly connected to the top of the moving block.
[0013] Preferably, the mounting groove is formed on the top of the base, and a handle is fixedly connected to one end of the bidirectional lead screw.
[0014] Preferably, there are two positioning plates, and heat dissipation holes are provided on the outside of the two positioning plates. The two positioning plates are arranged symmetrically.
[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0016] First, the electrical parameter tester is installed on the base using the mounting mechanism. The base is placed on a table, and the suction cup in the connecting groove at the bottom of the base adheres to the table surface to initially fix the base in place. Then, by turning the rotating rod, the gear rotates, causing the toothed plate meshing with the gear to move towards the edge of the table until the connecting seat reaches the edge. Then, by rotating the connecting seat, the concave connecting seat flips over, so that the concave end of the connecting seat faces the edge of the table. Then, the rotating rod is turned in the opposite direction to retract the toothed plate, causing the concave connecting seat to fit against one end of the table edge. Then, by rotating the threaded rod, the abutment block moves towards the bottom of the table until the abutment block fits against the bottom of the table, thus completing the base fixing operation and securing the electrical parameter tester on the base. This effectively prevents the instrument from colliding with it during testing, thus preventing measurement errors caused by instrument shaking, improving the accuracy and reliability of the test, and effectively preventing damage to the electrical parameter tester due to accidental drops or movement during testing.
[0017] Secondly, by placing the electrical parameter tester on the base, and then turning the double-acting screw by the handle, the two moving blocks move towards each other inside the mounting slot, which in turn moves the two positioning plates towards each other until one end of the positioning plate contacts and adheres to the surface of the electrical parameter tester, thus installing the electrical parameter tester. The heat can be dissipated through the heat dissipation holes on the outside of the positioning plate, achieving the effect of easy installation without the need for fixing with bolts or other objects.

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0025] Example 1
[0026] Please see Figures 1-5 An improved structure for fixing an electrical parameter tester includes a base 1, a fixing mechanism 2 and an installation mechanism 3 on the outside of the base 1.
[0027] The fixing mechanism 2 includes a slide groove 21 and a connecting groove 22. An adjustment groove is provided on the inner side of the slide groove 21. A rotating rod 23 is rotatably connected to the inner side of the adjustment groove. A gear 24 is fixedly connected to the outside of the rotating rod 23. A toothed plate 25 meshes with the top of the gear 24. A connecting seat 26 is rotatably connected to one end of the toothed plate 25. A threaded rod 27 is rotatably connected to the inner side of the connecting seat 26. An abutment block 28 is fixedly connected to one end of the threaded rod 27. A suction cup 29 is installed on the inner side of the connecting groove 22.
[0028] Multiple slides 21 are provided, and multiple slides 21 and connecting grooves 22 are provided on the outside of the base 1.
[0029] The toothed plate 25 is T-shaped, and one end of the toothed plate 25 is slidably connected to the inner side of the slide groove 21.
[0030] Multiple suction cups 29 are provided, and the multiple suction cups 29 are arranged in a linear array.
[0031] Using the above technical solution, the electrical parameter tester is installed on the base 1 via the installation mechanism 3. The base 1 is placed on a table, and the suction cup 29 in the connecting groove 22 at the bottom of the base 1 adheres to the table to initially fix the base 1, thus securing the base 1. Then, by turning the rotating rod 23, the gear 24 is driven to rotate, thereby causing the toothed plate 25 meshing with the gear 24 to move towards the edge of the table until the connecting seat 26 reaches the edge of the table. Then, by rotating the connecting seat 26, the concave connecting seat 26 is flipped, so that the concave end of the connecting seat 26 faces the edge of the table. Then, the rod is turned in the opposite direction. The rotating rod 23 retracts the toothed plate 25, thereby causing the concave connecting seat 26 to fit against one end of the table edge. Then, by rotating the threaded rod 27, the abutment block 28 is moved towards the bottom of the table until the abutment block 28 fits against the bottom of the table, thus completing the operation of fixing the base 1 and fixing the electrical parameter tester on the base 1. This effectively prevents the instrument from colliding during the test, thus preventing measurement errors caused by instrument shaking, improving the accuracy and reliability of the test, and effectively preventing damage to the electrical parameter tester caused by accidental drops or movement during the test.
[0032] Example 2
[0033] Please see Figures 1-5Furthermore, based on Embodiment 1, the following is obtained: the installation mechanism 3 includes an installation groove 31, a bidirectional lead screw 32 is rotatably connected to the inner side of the installation groove 31, a moving block 33 is threadedly connected to the outer side of the bidirectional lead screw 32, and a positioning plate 34 is fixedly connected to the top of the moving block 33.
[0034] Mounting slot 31 is provided on the top of base 1, and a handle 35 is fixedly connected to one end of bidirectional lead screw 32.
[0035] There are two positioning plates 34, and heat dissipation holes are provided on the outside of the two positioning plates 34. The two positioning plates 34 are arranged symmetrically.
[0036] With the above technical solution, the electrical parameter tester is placed on the base 1, and then the double-acting screw 32 is rotated by the handle 35, which in turn drives the two moving blocks 33 to move towards each other inside the mounting slot 31, thereby driving the two positioning plates 34 to move towards each other until one end of the positioning plate 34 contacts and adheres to the surface of the electrical parameter tester, thus installing the electrical parameter tester. The heat dissipation holes on the outside of the positioning plate 34 allow heat to dissipate, achieving the effect of easy installation without the need for fixing with bolts or other objects.
