[0001] This utility model relates to the field of battery testing, and in particular to a battery testing fixture. Background Technology
[0002] A battery test fixture is a device specifically designed for testing the electrical performance of batteries. It mainly consists of fixtures, probes, and other mechanisms. It is a specialized testing instrument that can safely, reliably, and quickly measure various data of a battery and is often used in battery research and development laboratories, battery production lines, quality inspection, and failure analysis.
[0003] The existing products use clamping arms of fixed height to hold the test batteries. This means that the instrument can only test one type of battery. If different types of batteries need to be tested, different test fixtures are required, which increases the workload of operators. At the same time, purchasing the corresponding machines will cost a lot of money and increase production costs.
[0004] The core problem with existing technology is that existing products use fixed, non-adjustable clamping arms, which lack the ability to compensate for battery size tolerances. This makes the products that the fixture can test limited. When different specifications of products need to be tested, it is time-consuming and labor-intensive to manually change the test fixtures, which seriously restricts production efficiency and significantly increases production costs. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a battery testing fixture, which aims to improve the problem that fixed fixtures cannot be adapted to the testing of products of various specifications.

A locking hole is provided on the outer wall of the housing. A locking pin is slidably connected to the inner wall of the locking hole. A pressing plate is fixedly connected to the outer wall of the locking pin. A sliding column is slidably connected to the inner wall of the pressing plate. A spring is sleeved on the outer wall of the sliding column. One end of the spring is fixedly connected to the outer wall of the pressing plate, and the other end is fixedly connected to the outer wall of the pressing plate.

A connecting column is fixedly connected to the outer wall of the fixing plate, and a metal contact plate is fixedly connected to the outer wall of the sliding column. A limit plate is fixedly connected to the outer wall of the sliding column.
[0007] Furthermore, a fixing plate one is fixedly connected to the outer wall of the outer shell, and a pressing column is threadedly connected inside the fixing plate one. A fixing plate three is fixedly connected to the outer wall of the fixing plate two. A fixing column is fixedly connected to the upper surface of the platform. A fixing block is fixedly connected to the upper surface of the fixing column. A rotating column is rotatably connected inside the fixing block. A connecting plate is fixedly connected to the outer wall of the rotating column. A clamping plate is fixedly connected to the upper surface of the connecting plate. Material is attached to the outer wall of the clamping plate. A spring two is fixedly connected to the inner wall of the connecting plate. One end of the spring two is fixedly connected to the inner wall of the connecting plate, and the other end of the spring two is fixedly connected to the inner wall of the fixing column.
[0008] Furthermore, a display screen is fixedly connected to the upper surface of the platform, and operation buttons are also fixedly connected to the upper surface of the platform.
[0009] Furthermore, the outer wall of the limiting plate is slidably connected to the inner wall of the outer shell, and the outer wall of the locking pin is slidably connected to the lower surface of the limiting plate.
[0010] Furthermore, the inner wall of the second pressing plate is slidably connected to the outer wall of the sliding column, and the outer wall of the metal contact plate is slidably connected to the outer wall of the outer casing.

[0013] Furthermore, both ends of the connecting plate are provided with fixing blocks, and both ends of the connecting plate are fixedly connected to the outer wall of the rotating column.
[0014] This utility model has the following beneficial effects: 1. In this utility model, the locking pin locks the outer shell by the cooperation of pressing plate one, pressing plate two, spring one and sliding column. Then, the pressing plate one, pressing plate two and fixing plate four drive the metal contact plate to move up and down under the limitation of the outer shell and the limiting plate. In this way, the height of the metal contact plate can be adjusted according to the product specifications, so that the clamp can be adapted to more types of products.
[0015] 2. In this utility model, the battery is placed between two clamping plates and pressed down. Under the pressure of the battery, the clamping plates will rotate to both sides around the rotating column as the rotation axis, thereby pulling the second spring connecting the connecting plate and the fixed column. Under the action of the second spring, the arc-shaped opening on the outer wall of the clamping plate will fit against the outer wall of the material and hold the material in place. In this way, batteries of different specifications can be clamped on the operating table to prevent the batteries from slipping during testing, while avoiding the drawbacks of traditional clamping methods that are prone to damaging the batteries.

[0018] 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.
[0019] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a battery testing fixture, including a platform 1, a slide rail 4 inside the platform 1, a slide plate 5 slidably connected to the inner wall of the slide rail 4, and a telescopic component on the upper surface of the slide plate 5. The entire telescopic component can slide above the platform 1 through the slide plate 5 and the slide rail 4 to adapt to batteries of different specifications. The telescopic assembly includes a housing 9, the lower surface of which is fixedly connected to the upper surface of the slide plate 5. A locking hole 10 is provided on the outer wall of the housing 9, and a locking pin 13 is slidably connected to the outer wall of the locking hole 10. A pressing plate 16 is fixedly connected to the outer wall of the locking pin 13. The pressing plate 16 controls the locking pin 13 to lock and unlock the locking hole 10 on the outer wall of the housing 9. A sliding pin 15 is slidably connected to the inner wall of the pressing plate 16, and a spring 18 is sleeved on the outer wall of the sliding pin 15. One end of the spring 18 is fixedly connected to the outer wall of the pressing plate 16, and the other end is fixedly connected to the outer wall of the pressing plate 26. A fixing plate 17 is slidably connected to the inner wall of the pressing plate 16. By moving the pressing plate 16 under the limit of the sliding column 15, the spring 18 can be compressed. When the locking column 13 moves to the desired height position, the spring 18 can reset the pressing plate 16, thereby automatically locking the locking column 13 into the lock hole 10. The inner wall of the pressing plate 16 is slidably connected to the fixing plate 27, the outer wall of the fixing plate 27 is fixedly connected to the connecting column 14, the outer wall of the connecting column 14 is fixedly connected to the metal contact plate 12, and the outer wall of the sliding column 15 is fixedly connected to the limit plate 11. The pressing plate 16 is connected to the fixing plate 27, which drives the connecting column 14, thereby driving the metal contact plate 12, to achieve the effect of telescopic adjustment.
[0020] Specifically, by pinching the first pressing plate 16 and the second pressing plate 26, the first pressing plate 16 and the second pressing plate 26 move towards the center under the limitation of the sliding column 15, compressing the first spring 18. The first pressing plate 16 and the second pressing plate 26 drive the locking column 13 to move inward, releasing the locking column 13 from locking the locking holes 10 on both sides of the outer shell 9. Then, pull the first pressing plate 16 and the second pressing plate 26 upward, so that the first pressing plate 16 and the second pressing plate 26, under the limitation of the limiting plate 11 and the outer shell 9, drive the connecting column 14 through the fixing plate 4 27, and then drive the metal contact plate 12 to move upward. When adjusted to the appropriate position, release your hand so that the locking column 13 locks the corresponding height of the locking holes 10 on both sides of the outer shell 9. This locks the height of the metal contact plate 12.
[0021] Reference Figure 4 - Figure 5A fixing plate 6 is fixedly connected to the outer wall of the outer shell 9. A pressing column 7 is threadedly connected inside the fixing plate 6. The fixing plate 6 is used to connect the pressing column 7 and the outer shell 9. By rotating the pressing column 7, the lower surface of the pressing column 7 abuts against the upper surface of the platform 1, thereby fixing the position of the telescopic component. A fixing plate 19 is fixedly connected to the outer wall of the fixing plate 17. The fixing plate 19 is used to fix the fixing plate 17. A fixing column 22 is fixedly connected to the upper surface of the platform 1. A fixing block 21 is fixedly connected to the upper surface of the fixing column 22. A rotating column 23 is rotatably connected inside the fixing block 21. A connecting plate 24 is fixedly connected to the outer wall of the rotating column 23. A clamping plate 20 is fixedly connected to the upper surface of the connecting plate 24. The connecting plate 24 is connected to the fixing column 22 and the fixing block 21. The connecting plate 24 is a rotating shaft used for the clamping plate 20 to deflect when it is squeezed by the battery. Material 8 is attached to the outer wall of the clamping plate 20. A spring 25 is fixedly connected to the inner wall of the connecting plate 24. One end of spring 25 is fixedly connected to the inner wall of connecting plate 24, and the other end of spring 25 is fixedly connected to the inner wall of fixed column 22. The clamping plate 20 clamps the material 8 by the pulling of spring 25. A display screen 2 is fixedly connected to the upper surface of platform 1, and an operation button 3 is fixedly connected to the upper surface of platform 1. The display screen 2 is controlled by operation button 3 to display various data of material 8. The outer wall of limiting plate 11 is slidably connected to the inner wall of outer shell 9. The outer wall of locking column 13 is slidably connected to the lower surface of limiting plate 11. The inner wall of pressing plate 26 is slidably connected to the outer wall of sliding column 15. The outer wall of metal contact plate 12 is slidably connected to the outer wall of outer shell 9. Connecting column 14 is set inside outer shell 9. The outer wall of pressing plate 16 is attached to the outer wall of fixed plate 3 19. The inner wall of pressing plate 26 is slidably connected to the outer wall of fixed plate 27. The inner wall of pressing plate 26 is slidably connected to the outer wall of fixed plate 4 27. Fixed blocks 21 are provided at both ends of connecting plate 24. Both ends of connecting plate 24 are fixedly connected to the outer wall of rotating column 23.
[0022] Specifically, when material 8 is placed between two clamping plates 20 and pressed down, the clamping plates 20 will rotate to both sides with the rotating column 23 as the axis of rotation under the pressure of material 8, thereby pulling the spring 25 connecting the connecting plate 24 and the fixing column 22. Under the action of the spring 25, the arc-shaped opening on the outer wall of the clamping plate 20 fits against the outer wall of the material 8 and clamps the material 8.
[0023] Working principle: When this battery testing fixture is needed, first adjust the two telescopic mechanisms on platform 1 according to the specifications of the battery being tested. Hold the first pressing plate 16 and the second pressing plate 26 by hand, causing them to move towards the center under the limit of the sliding column 15 and compress the first spring 18. The first pressing plate 16 and the second pressing plate 26 then drive the locking column 13 inward to release the locking of the locking column 13 onto the locking holes 10 on both sides of the outer casing 9. Then, pull the first pressing plate 16 and the second pressing plate 26 upward, causing them to move upward through the fixing plate 4 27 under the limit of the limiting plate 11 and the outer casing 9. When adjusted to the appropriate position, release the hand so that the locking column 13 aligns with the corresponding locking holes 10 on both sides of the outer casing 9. The height of the metal contact plate 12 can be locked by locking the height of the locking hole 10. Then, the material 8 is placed between the two clamping plates 20 and pressed down. The clamping plates 20 will rotate to both sides with the rotating column 23 as the rotation axis under the pressure of the material 8, thereby pulling the spring 25 connecting the connecting plate 24 and the fixing column 22. Under the action of the spring 25, the arc-shaped opening on the outer wall of the clamping plate 20 fits against the outer wall of the material 8 and clamps the material 8, so that one end of the material 8 is pressed tightly against the fixed telescopic component. Then, the other telescopic component is lowered to the other end of the material 8 by the sliding plate 5, and then the pressing column 7 is rotated so that the pressing column 7 is tightly fixed above the platform 1 through the threaded hole on the fixing plate 6. Then, various data of the material 8 can be measured through the display screen 2 and the operation button 3.
