Description

Technical Field

[0001] This utility model relates to the field of high-voltage electrical insulation components, and in particular to a testing fixture for high-voltage electrical insulation components. Background Technology

[0002] High-voltage electrical insulation components refer to components used in high-voltage electrical equipment to isolate live parts from other components or ground potential, thereby preventing current from passing through and ensuring the safe and stable operation of electrical equipment. An insulating rod is an insulating tool mainly used for operating high-voltage electrical equipment. It enables operators to maintain a safe distance from high-voltage live parts and avoid electric shock accidents. When conducting withstand voltage tests, testing fixtures are used to clamp and limit the insulating rod.

[0003] Existing technologies, such as the utility model with publication number CN212207561U, relate to the field of electrical insulation component testing technology. Specifically, it discloses a testing fixture for high-voltage electrical insulation components, including a base plate. A strip-shaped groove is formed on the top of the base plate, and two sliding blocks are slidably connected to the groove. A support column is fixedly connected to the top of each sliding block, and a fixing column is fixedly connected to the top of the support column. A fixing plate is fixedly connected to the top of the fixing column, and a threaded through hole is formed on the outer side of the fixing plate. This utility model, through its testing instrument and terminals, can conveniently test the insulating rods that need to be tested. The anti-slip plate and support feet provide stable support for the device. The rotating plate and threaded rod allow the two support columns to move, facilitating compatibility with insulating rods of different lengths. This addresses the issue of existing testing equipment requiring clamping of the insulating rod before powering on for performance testing. However, in practice, it was found that the fixed clamping device could not be used to test insulating rods of different specifications, and the clamping process caused wobbling, resulting in fluctuating test results that could not accurately reflect the true performance of the insulating rod.

[0004] In daily work, it has been found that although the above-mentioned insulating rod testing fixture can be adjusted according to the length of the insulating rod, the overall structure is relatively fixed and occupies a large space, making it inconvenient to store and taking up a lot of space in the tool storage room. At the same time, precise adjustment requires the use of measuring tools, which makes the overall operation inconvenient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as inconvenience in storage and precise adjustment, by proposing a testing fixture for high-voltage electrical insulation components.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a test fixture for high-voltage electrical insulation components, comprising a movable plate one, a movable plate two, and an adjusting device. The movable plate two is located on one side of the movable plate one. Two supports are fixedly connected to the surfaces of both the movable plate one and the movable plate two. Clamping devices are provided on the surfaces of the two supports. The adjusting device is disposed on the surfaces of the movable plate one and the movable plate two, and includes two seats, a seat one and a seat two, which are respectively fixedly connected to the surfaces of the movable plate one and the movable plate two. Rods one and two are rotatably connected to the inner walls of the seats one and the seats two, respectively. Two rectangular blocks and a concave block are fixedly connected to the surfaces of rod one and rod two, respectively. The surface of the rectangular block has a through hole, and the surface of the concave block is provided with a limiting component and a scale. The surface of the movable plate one has a groove for the movable plate two to be inserted. With the above components, during use, the concave block can be restricted to slide on the rectangular block by the limiting component. In conjunction with the scale, the position between movable plate one and movable plate two can be adjusted. When storing, the concave block is removed from the rectangular block, and then movable plate two is inserted into movable plate one to achieve storage and reduce space occupation.

[0007] Preferably, the limiting component includes a pin, which is slidably connected to the inner wall of the concave block. A spring is sleeved on the surface of the pin, and the two ends of the spring are fixedly connected to the pin and the surface of the concave block, respectively. With the above components, when in use, the pin on the surface of the concave block can be inserted into the through hole on the surface of the rectangular block, and with the elastic force of the spring, the stability of the pin is ensured, so that the concave block can slide on the rectangular block and the position can be adjusted stably.

[0008] Preferably, the surfaces of rod one and rod two are provided with positioning components, each including iron block one and iron block two, which are fixed to the surfaces of rod one and rod two respectively. Two magnetic rings one and two are fixedly connected to the surfaces of moving plate one and moving plate two respectively, and are magnetically connected to iron block one and iron block two respectively. Through these components, during use and storage, the two rectangular and concave blocks can be rotated using rod one and rod two respectively, making them perpendicular to moving plate one and moving plate two respectively. Subsequently, magnetic ring one and magnetic ring two can be attracted and positioned to iron block one and iron block two respectively, ensuring the stability of rod one and rod two.

[0009] Preferably, an auxiliary component is provided between the first movable plate and the second movable plate. The auxiliary component includes a rotating rod, which is rotatably connected to the inner wall of the first movable plate. Each end of the rotating rod is fixedly connected to a clamp. Both sides of the second movable plate are fixedly connected to cylindrical rods, which engage with the inner walls of the clamps. With the above components, when the second movable plate is inserted into the groove on the surface of the first movable plate, the rotating rod can be rotated so that the cylindrical rods can be engaged in the inner walls of the clamps, thus achieving stability during overall storage.

[0010] Preferably, the clamping device includes a clamping block one fixed on a bracket, a clamping block two slidably connected to the surface of the bracket, an insulating frame fixedly connected to the upper ends of the two brackets, a cylinder fixedly connected to the surface of the insulating frame, an insulating block fixedly connected to the output end of the cylinder, and the insulating block fixedly connected to the surface of the clamping block two. Through the above components, the insulating rod can be placed on the clamping block one, and then the cylinder, in conjunction with the insulating block, drives the clamping block two to move and clamps the pair of insulating rods, thereby improving the overall stability.

[0011] Preferably, the clamping block one and clamping block two are composed of a plate and multiple arc-shaped pieces on the plate.

[0014] 2. In this utility model, by setting up a clamping device, the placed insulating rod can be clamped by a cylinder, so that there is no need for manual contact with the tooling parts to complete the positioning, thereby effectively reducing the possibility of dangerous accidents and improving overall safety.

Clamping devices 5 are provided on the surfaces of the two supports 3. The adjustment device 4 is provided on the surfaces of the movable plate 1 and the movable plate 2.

[0023] Specifically, the adjustment device 4 includes two seats 41 and 42. The seats 41 and 42 are fixedly connected to the surfaces of the moving plate 1 and the moving plate 2, respectively. The inner walls of the seats 41 and 42 are rotatably connected to the rods 43 and 44, respectively.

The surface of the concave block 46 is provided with a limit component 47. The surface of the rectangular block 45 is provided with a scale 411. The surface of the moving plate 1 is provided with a groove 410 for the moving plate 2 to be inserted.

[0024] In this embodiment: When in use, the concave block 46 can be restricted to slide on the rectangular block 45 by the limiting component 47, thereby adjusting the position between the moving plate 1 and the moving plate 2 in conjunction with the scale 411. When storing, the concave block 46 is removed from the rectangular block 45, and then the moving plate 2 is inserted into the moving plate 1 to achieve storage and reduce the space occupied.

[0025] Specifically, the limiting component 47 includes a pin 471, which is slidably connected to the inner wall of the concave block 46. A spring 472 is sleeved on the surface of the pin 471, and the two ends of the spring 472 are fixedly connected to the pin 471 and the surface of the concave block 46, respectively. In use, the pin 471 on the surface of the concave block 46 can be inserted into the through hole 412 on the surface of the rectangular block 45, and with the elastic force of the spring 472, the stability of the pin 471 is ensured, so that the concave block 46 can slide on the rectangular block 45 and the position can be adjusted stably.

[0026] Specifically, positioning components 48 are provided on the surfaces of rod 1 43 and rod 2 44. The positioning components 48 include iron block 1 482 and iron block 2 484, which are fixed on the surfaces of rod 1 43 and rod 2 44 respectively. Two magnetic rings 1 481 and 2 483 are fixedly connected to the surfaces of moving plate 1 and moving plate 2 respectively. Magnetic rings 1 481 and 2 483 are magnetically connected to iron block 1 482 and iron block 2 484 respectively.

[0027] In this embodiment: When in use, when storing, the two rectangular blocks 45 and concave blocks 46 can be rotated by rod 1 43 and rod 2 44 respectively, so that the rectangular blocks 45 and concave blocks 46 are perpendicular to the moving plate 1 and moving plate 2 respectively. Then, the magnetic ring 1 481 and magnetic ring 2 483 can be attracted and positioned with the iron block 1 482 and iron block 2 484 respectively, ensuring the stability of rod 1 43 and rod 2 44.

[0028] Specifically, an auxiliary component 49 is provided between the movable plate 1 and the movable plate 2. The auxiliary component 49 includes a rotating rod 491, which is rotatably connected to the inner wall of the movable plate 1. The two ends of the rotating rod 491 are respectively fixedly connected to the clips 492. The two sides of the movable plate 2 are respectively fixedly connected to the cylindrical rods 493, which are engaged with the inner wall of the clips 492. When the movable plate 2 is inserted into the groove 410 on the surface of the movable plate 1, the rotating rod 491 can be rotated so that the cylindrical rods 493 can be engaged in the inner wall of the clips 492, thereby achieving stability when the whole is stored.

[0030] In this embodiment, the insulating rod can be placed on clamping block 51, and then the cylinder 54, in conjunction with the insulating block 55, drives clamping block 52 to move, and clamps the insulating rod with clamping block 51, thereby improving the overall stability.

[0031] Specifically, clamping block 1 51 and clamping block 2 52 are composed of a plate and multiple arc-shaped pieces on the plate.

[0032] Working principle: During use, when assembly and testing are required, the clamp 492 can be rotated to disengage the cylindrical rod 493 from the clamp 492, and the second movable plate 2 can be moved out of the groove 410 of the first movable plate 1. After removal, the first rod 43 and the second rod 44 are rotated to flatten the rectangular block 45 and the concave block 46. At the same time, the pin 471 is pulled, and the spring 472 is stressed. When the rectangular block 45 can be inserted into the inner wall of the concave block 46, the pin 471 is released. The spring 472 drives the pin 471 to insert into the through hole 412 on the surface of the rectangular block 45. Then, the first movable plate 1 or the second movable plate 2 can be slid, and the concave block 46 can slide on the rectangular block 45. With the help of the scale 411, precise adjustment can be achieved. After adjustment, the insulating rod can be placed on the clamp 51. The cylinder 54, in conjunction with the insulating block 55, drives the clamping block 2 52 to move, and in conjunction with the clamping block 1 51, clamps the insulating rod. Then, the insulating rod can be tested. When it needs to be stored, pull the pin 471, the spring 472 is stressed, and the rotating rod 1 43 and rod 2 44 separate the rectangular block 45 and the concave block 46, so that the rectangular block 45 and the concave block 46 are respectively perpendicular to the moving plate 1 and the moving plate 2. Then, the magnetic ring 1 481 and magnetic ring 2 483 can be attracted and positioned with the iron block 1 482 and the iron block 2 484 respectively. When the moving plate 2 2 is pushed into the groove 410 on the surface of the moving plate 1, the rotating rod 491 is rotated. The rotating rod 491, in conjunction with the clamp 492, makes the cylindrical rod 493 snap into the inner wall of the clamp 492, achieving positioning, and then it can be stored.
