Description

Technical Field

[0001] The present invention relates to the technical field of voltage calibration, and in particular to an anti-biased clamping battery voltage calibration device. Background Art

[0002] A UPS (uninterruptible power supply) is a critical power supply device. When the mains power goes out or the grid fails, the UPS can immediately switch to battery power to ensure continuous equipment operation and avoid data loss or business interruption. For example, critical scenarios such as data centers and medical equipment rely on this function to maintain operation. The UPS is usually equipped with a battery. To ensure stable battery operation, a voltage calibration device is required to test and calibrate the battery voltage.

[0003] In the prior art, battery voltage calibration devices are relatively common in battery testing. The battery voltage calibration device eliminates the inherent errors of the voltage sensor through calibration to ensure that the voltage data of the battery cell or component accurately reflects the actual status and avoids overcharging / undercharging due to misjudgment. When the battery voltage calibration device is in use, the test clamp needs to be clamped on the battery for testing. The traditional test clamp clamps the test clamp on the battery by squeezing the spring. Fixing the test clamp only by squeezing the spring is not stable and firm enough. If it accidentally touches the power cord, it may easily cause the test clamp to shift or fall off, thereby affecting the test and calibration of the battery voltage. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 It can be seen that the present invention provides a technical solution: a battery voltage calibration device with anti-biased clamping, comprising a voltage calibrator body 1, a display screen 2, an operation button 3, a wiring hole 4 and a test clip 5. The front of the voltage calibrator body 1 is respectively equipped with a display screen 2 and an operation button 3, and the front of the voltage calibrator body 1 near the operation button 3 is provided with a wiring hole 4, the wiring hole 4 is connected to the test clip 5 through a power cord, a fixed seat 6 is provided on the outside of one end of the test clip 5, a guide rod 7 and a reset spring 8 are respectively installed inside the fixed seat 6, one end of the reset spring 8 is connected to a moving block 9, and a groove 10 is provided inside the moving block 9 away from the reset spring 8.

[0026] In the battery voltage calibration device with anti-bias clamping, when the end of the plastic threaded rod 11 moves out from the inside of the groove 10, the reset spring 8 can drive the moving block 9 to reset, thereby driving the test clamp 5 to reset.

[0027] exist Figure 1-Figure 4 Middle: The internal thread of the fixing base 6 near the groove 10 is connected with a plastic threaded rod 11, the top of the test clamp 5 and the moving block 9 are connected with a connecting shaft 12, and the two connecting shafts 12 are movably connected with a rotating block 13. A wire groove 14 is opened inside the fixing base 6 near a group of test clamps 5.

[0028] In the battery voltage calibration device with anti-bias clamping, the wire groove 14 can connect a set of test clips 5 to the power line.

[0029] exist Figure 1-Figure 3 Middle: Four groups of rotating blocks 13 are provided inside the fixing base 6 , and a sliding structure is formed between the test clamp 5 and the guide rod 7 .

[0030] In the anti-bias clamping battery voltage calibration device, a sliding structure is formed between the test clamp 5 and the fixing seat 6.

[0031] In practice, the battery voltage calibration device can test and calibrate the battery voltage, thereby helping to extend the battery's service life. Conventional test clips 5 are not stable and secure when clamped, making them prone to drifting and falling off. Insert one end of the power cord of the test clip 5 into the wiring hole 4, then move the test clips 5 to the outside of the battery test column, so that both sets of test clips 5 are located outside the battery test column. At this point, the plastic threaded rod 11 can be rotated forward. As the plastic threaded rod 11 rotates, its end can rotate toward the movable block 9. When one end of the plastic threaded rod 11 rotates and moves into the groove 10, the end of the plastic threaded rod 11 pushes the movable block 9. As the movable block 9 moves, it drives the connecting shaft 12 at its top to move. As the connecting shaft 12 moves, the rotating block 13 drives the connecting shaft 12 at the top of the test clip 5 to move. At this point, the test clip 5 can slide with the guide rod 7. Simultaneously, the rotating block 13 can rotate via the two sets of connecting shafts 12, allowing the two sets of test clips 5 to move closer to each other. As the movable block 9 moves, it compresses the return spring 8.

[0032] See Figure 1-Figure 4 It can be seen that when the two sets of test clips 5 are moved toward each other to the specified position, they can be clamped and fixed on the test column of the battery, so that the test clips 5 can be stably and firmly clamped on the battery. The plastic threaded rod 11 can effectively prevent the test clips 5 from being offset or falling due to accidentally touching the power cord, thereby improving the stability and firmness of the test clips 5 when clamping.

[0033] exist Figure 1 、 Figure 2 、 Figure 5 and Figure 6 Middle: A storage box 15 is bonded to the top of the voltage calibrator body 1, and a box cover 16 is movably connected to the top of the storage box 15 of the voltage calibrator body 1 through a rotating shaft. A U-shaped seat 17 is connected to the outside of the box cover 16, and a handle 18 is connected to the top of the box cover 16.

[0034] The anti-bias clamping battery voltage calibration device can be carried by lifting the voltage calibrator body 1 as a whole through the handle 18.

[0035] exist Figure 1 、 Figure 2 、 Figure 5 and Figure 6Middle: A threaded column 19 is welded on the surface of the voltage calibrator body 1 close to the U-shaped seat 17, and a threaded ring 20 is threadedly connected to the outer side of the threaded column 19. A fixed plate 21 is slidably connected to the outer side of the threaded column 19, and a positioning pin 22 is connected to the bottom of the fixed plate 21. A through hole matching the size of the positioning pin 22 is opened at the bottom of the U-shaped seat 17, and the common height of the fixed plate 21 and the positioning pin 22 is less than the inner height of the U-shaped seat 17.

[0036] The anti-bias clamping battery voltage calibration device, the fixing plate 21 and the positioning pin 22 are used to fix the U-shaped seat 17.

[0037] In specific implementation, when the battery voltage calibration device is in use, the test clip 5 is usually placed separately, which makes it difficult to carry the test clip 5 with the voltage calibrator body 1 and easy to lose. The test clip 5 and the power cord are placed in the storage box 15, and the box cover 16 can be flipped through the rotating shaft so that the box cover 16 can cover the storage box 15. At this time, the U-shaped seat 17 can be moved to the side of the threaded column 19. At this time, the fixing plate 21 can be pulled upward, and the threaded column 19 can be used to make the top of the fixing plate 21 slide to the bottom of the threaded ring 20, so that the end of the fixing plate 21 can be rotated toward the inner side of the U-shaped seat 17. When the end of the fixing plate 21 is just completely rotated and moved to the inner side of the U-shaped seat 17, the fixing plate 21 can be loosened so that the fixing plate 21 can slide downward, so that the positioning pin 22 can pass through the through hole of the U-shaped seat 17, and tighten the threaded ring 20 so that the bottom of the threaded ring 20 can be rotated and moved to the top of the fixing plate 21, thereby fixing the fixing plate 21. At this time, the fixing plate 21 can be connected to the U-shaped seat 17.

[0038] See Figure 1 、 Figure 2 、 Figure 5 and Figure 6 It can be seen that the test clip 5 and the power cord can be stored in the storage box 15, the box cover 16 can prevent loss, and the handle 18 can be used to simply and conveniently carry the voltage calibrator body 1 by hand.

[0039] To sum up, when using the battery voltage calibration device with anti-bias clamping, one end of the power cord of the test clip 5 is inserted into the wiring hole 4, and then the test clip 5 is moved to the outside of the battery test column, so that both groups of test clips 5 are located outside the battery test column. At this time, the plastic threaded rod 11 can be rotated forward. When the two groups of test clips 5 move toward each other to the specified position, they can be clamped and fixed on the test column of the battery, so that the test clip 5 can be stably and firmly clamped on the battery. The plastic threaded rod 11 can effectively prevent the test clip 5 from being offset or falling due to accidental contact with the power cord, thereby improving the stability and firmness of the test clip 5 when clamping. The test clip 5 and the power cord can be stored through the storage box 15, the box cover 16 can prevent loss, and the voltage calibrator body 1 can be simply and conveniently carried by hand through the handle 18.
