Description

Technical Field

[0001] This utility model relates to the field of debugging tool technology, and in particular to a convenient synchronous motor differential debugging tool. Background Technology

[0002] The portable synchronous motor differential commissioning tool is a device specifically designed for commissioning differential protection of synchronous motors, which are very common in industrial applications, especially in large machinery and power generation equipment.

[0003] In existing technologies, the display screen of the ammeter in some differential adjustment tools is difficult to clean. If the display screen is not clean, dust, oil, fingerprints, or other impurities will obscure part of the display area, causing the screen to become blurry and affecting the viewing experience. This makes the numbers difficult to read, affects the display effect, and causes the test results to deviate. During use, the display screen will come into contact with dust and other tiny particles. If it is not cleaned regularly, wear marks will accumulate with time and repeated use. Difficulty in regularly cleaning the display screen will increase the wear marks and affect its service life. Therefore, a convenient synchronous motor differential adjustment tool is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a convenient synchronous motor differential adjustment tool, which aims to improve the problems in the prior art where impurities obscure the display area, causing image blurring, and the difficulty in regular cleaning exacerbates wear and scratches and reduces lifespan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable synchronous motor differential adjustment tool includes a connecting housing. A display screen is fixedly connected inside the connecting housing. A rotating shaft is slidably connected to the rear of the connecting housing. A support assembly for fixation is fixedly connected to the inner wall of the connecting housing. A connecting rod is fixedly connected to the front side of the rotating shaft. A rotating disk is fixedly connected to the front side of the connecting rod. A connecting column is fixedly connected to the front side of the rotating disk. A rotating frame is slidably connected to the outside of the connecting column. A connecting column is slidably connected to the bottom inner wall of the rotating frame. A square slider is fixedly connected to the rear side of the connecting column. A scraper is fixedly connected to the bottom of the square slider. A disassembly assembly for easy maintenance is fixedly connected to the inner wall of the connecting housing. By manually rotating the rotating shaft, the connecting rod rotates, causing the rotating disk to rotate. The connecting column causes the rotating frame to swing, and the rotating frame causes the square slider to move, moving the scraper to remove stains from the display screen.

[0007] As a further description of the above technical solution:

[0008] The disassembly assembly includes two handles. A connecting rod two is fixedly connected to the adjacent side of each handle. A baffle is rotatably connected to the front side of the connecting rod two. A rotating column is rotatably connected to the rear side of the connecting rod two. A sliding column is slidably connected to the opposite side of the rotating column. A support column is fixedly connected to the opposite side of the sliding column. A fixing plate is fixedly connected to the adjacent side of the rotating column. A bottom shell is slidably connected to the adjacent side of the fixing plate. A spring is fixedly connected to the rear side of the rotating column. By manually pulling the handle, the handle moves the connecting rod two, which in turn moves the rotating column. When the rotating column moves, it moves the fixing plate, fixing the fixing plate to the bottom shell. The spring further reinforces the fixation of the bottom plate.

[0009] As a further description of the above technical solution:

[0010] The support assembly includes a support plate, the rear side of which is fixedly connected to the inner wall of the connecting shell. A support rod is fixedly connected to the bottom of the support plate, and a square block is fixedly connected to the bottom of the support rod. The support plate is fixed to the support rod, and the support rod is fixed to the square block, which further enhances the support strength.

[0011] As a further description of the above technical solution:

[0012] The rear side of the support rod is fixedly connected to the inner wall of the connecting shell, and the rear side of the square block is fixedly connected to the inner wall of the connecting shell. The support rod fixes the block to the inner wall of the connecting shell, further enhancing the support strength.

[0013] As a further description of the above technical solution:

[0014] The top rear side of the rotating frame is rotatably connected to the front side of the support plate, and the outside of the square slider is slidably connected to the inside of the square block. The square slider slides inside the square block to support a more stable sliding motion.

[0015] As a further description of the above technical solution:

[0016] The rear side of the scraper is slidably connected to the front side of the display screen, and the inner wall of the connecting shell is provided with a second slot. The scraper slides on the display screen to further clean the display screen.

[0017] As a further description of the above technical solution:

[0018] The interior of the connecting shell is fixedly connected to the exterior of the two support columns. The front side of the baffle is fixedly connected to the inner wall of the connecting shell and fixed to the exterior of the connecting shell by the support columns, further providing support for the support columns.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the connecting shell is slidably connected to the outside of the bottom shell, and the inside of the rotating column is provided with a slot, which slides inside the connecting shell through the bottom shell, further providing quick disassembly.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating shaft is manually driven to rotate. The rotation of the rotating shaft is transmitted to the rotating disk through the connecting rod. Since the connecting column is slidably connected to the rotating frame, the rotating frame drives the square slider to move left and right. The square slider drives the scraper to move to clean the dust on the surface. Regularly cleaning the display screen ensures that dust, oil stains or fingerprints and other impurities do not obstruct the display area, which can maintain the clarity of numbers and graphics. Regularly cleaning the display screen can reduce the generation of wear and scratches, protect the surface of the display screen, and extend the service life of the display screen.

[0023] 2. In this utility model, by pulling the handles to both sides, the connecting rod two moves to both sides. While the rotating column moves to both sides under the action of the connecting rod two, the spring is used to reset the rotating column. The rotation of the rotating column will cause the sliding column to slide within a certain range. When the rotating column rotates, it changes the position of the fixed plate. After removing the bottom shell, some vulnerable parts can be individually packaged and protected to reduce the risk of damage. The interior can be thoroughly cleaned to remove these impurities and ensure the normal operation of the tool. Removing the back shell makes these parts easier to access and facilitates maintenance operations. Attached Figure Description

A rotating shaft 2 is slidably connected to the rear of the connecting shell 1. A support assembly for fixation is fixedly connected to the inner wall of the connecting shell 1. A connecting rod 3 is fixedly connected to the front side of the rotating shaft 2. When an external force is applied to the rotating shaft 2, the rotating shaft 2 can rotate and move back and forth, thereby driving the connecting rod 3 and subsequent components to perform corresponding movements. A rotating disk 4 is fixedly connected to the front side of the connecting rod 3, transmitting the rotation and movement of the rotating shaft 2 to the rotating disk 4. A connecting column 5 is fixedly connected to the front side of the rotating disk 4. A rotating frame 6 is slidably connected to the outside of the connecting column 5. Since the connecting column 5 and the rotating frame 6 are slidably connected, the circumferential movement of the connecting column 5 will drive the rotating frame 6 to perform specific movements. A connecting column 7 is slidably connected to the bottom inner wall of the rotating frame 6. A square slider 8 is fixedly connected to the rear side of the connecting column 7. The connecting column 7 is cylindrical or square, etc. A scraper 9 is fixedly connected to the bottom of the square slider 8.

The support column 17 is usually cylindrical or square and is used to provide support and stability. A fixing plate 20 is fixedly connected to the adjacent side of the rotating column 16. Its function is to connect the rotating column 16 and the bottom shell 21 and to transmit force during disassembly. The bottom shell 21 is slidably connected to the adjacent side of the fixing plate 20. The bottom shell 21 is the bottom outer shell of the tool and usually cooperates with other components to protect the internal structure. A spring is fixedly connected to the rear side of the rotating column 16. The spring is used to reset the rotating column 16.

[0035] Reference Figures 3 to 6 The support assembly includes a support plate 10, the rear side of which is fixedly connected to the inner wall of the connecting shell 1. The support plate 10 can be firmly fixed inside the connecting shell 1, providing stable support for other components. A support rod 11 is fixedly connected to the bottom of the support plate 10, and the rear side of the support rod 11 is also fixedly connected to the inner wall of the connecting shell 1. This double connection method greatly improves the overall stability of the support assembly.

The rotating frame 6 can rotate stably under the support of the support plate 10, and can also withstand certain axial and radial forces. The square slider 8 is externally slidably connected to the inside of the square block 12. This connection allows the square slider 8 to perform precise linear movement within the constraints of the square block 12. The rear side of the scraper 9 is slidably connected to the front side of the display screen 23. During operation, the movement of the scraper 9 causes the display screen 23 to slide accordingly, ensuring that the operator can always clearly see the information on the display screen. The inner wall of the connecting shell 1 has a slot 22. The inside of the connecting shell 1 is fixedly connected to the outside of the two support columns 17. The front side of the baffle 15 is fixedly connected to the inner wall of the connecting shell 1. The support columns 17 cooperate with the disassembly assembly to provide support for the disassembly and installation of the tool. The inner wall of the connecting shell 1 is slidably connected to the outside of the bottom shell 21. The inside of the rotating column 16 has a slot 19 for sliding with other components.

[0036] Working Principle: First, when the screen of the ammeter needs to be cleaned, the rotating shaft 2 is manually driven to rotate. The rotation of the rotating shaft 2 is transmitted to the rotating disk 4 through the connecting rod 3, causing the rotating disk 4 to start rotating. The connecting post 5 on the rotating disk 4 moves in a circular motion with the rotating disk 4. Since the connecting post 5 is slidably connected to the rotating frame 6, the circular motion of the connecting post 5 will push the rotating frame 6 to swing left and right. The rotating frame 6 drives the square slider 8 to move left and right. The square slider 8 drives the scraper 9 to move to clean the dust on the surface of the display screen 23. Regularly cleaning the display screen 23 ensures that dust, oil, fingerprints, and other impurities do not obstruct the display area, maintaining the clarity of numbers and graphics. Regularly cleaning the display screen 23 can reduce the generation of wear and scratches, protect the surface of the display screen 23, and extend the service life of the display screen 23.

[0037] Secondly, when it is necessary to repair or replace the internal components of the ammeter, by pulling the handle 13 to both sides, the connecting rod 14 is moved to both sides. The rotating column 16, driven by the connecting rod 14, moves to both sides and rotates around its axis. Since a sliding column 18 is slidably connected to the opposite side of the rotating column 16, the rotation of the rotating column 16 causes the sliding column 18 to slide within a certain range. A spring is used to reset the rotating column 16. The fixing plate 20 is fixed to the rotating column 16. When the rotating column 16 rotates, the position of the fixing plate 20 changes. After removing the bottom cover 21, some vulnerable parts can be individually packaged and protected to reduce the risk of damage. A thorough cleaning of the interior can be performed to remove impurities, ensuring the normal operation of the tool. Removing the bottom cover makes these parts more accessible for maintenance.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
