Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a portable battery tester. Background Technology

[0002] A battery tester is a device for real-time and comprehensive online testing and management of batteries in power systems. During testing, a test pen is typically inserted into the positive and negative terminals of the battery to measure various values ​​such as current, voltage, and resistance. Batteries are now widely used in the management of power storage batteries in industries such as power, communications, transportation, and automobiles.

[0003] Most battery testers on the market have test pens and connecting cables that are not convenient to store during transport. Users often simply wrap them around the outside of the tester after use, which can easily damage the test pens and connecting cables during transport and make the tester dirty.

[0004] A portable battery tester disclosed in Chinese Utility Model Patent Application Publication CN202120729967.9 includes: a tester, a pull ring on the top outer side of the tester, and locking rings on the left and right sides of the tester, with adjusting bolts disposed on the outer sides of the locking rings. While this portable battery tester avoids damage to the connecting cable from friction with external objects during storage and transport, it has a drawback when testing smaller batteries. The smaller batteries are prone to shifting, making it inconvenient to contact the test pen with the two testing terminals of the smaller battery, thus reducing testing efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 6This utility model provides a technical solution: a portable battery tester, including a protective shell 1, a sliding cover 2 slidably connected to the top of the protective shell 1, a tester body 3 fixedly connected inside the protective shell 1, two detection columns 4 fixedly connected inside the protective shell 1, connecting wires 5 electrically connected to the two detection ends of the tester body 3 respectively between the two detection columns 4, a support leg 6 fixedly connected inside the protective shell 1, a winding shell 7 fixedly connected to the top of the support leg 6, a support plate 8 fixedly connected to the top of the detection column 4, a rotating shell 9 rotatably connected to the top of the support plate 8, a spring 10 fixedly connected to the top of the support plate 8, the spring 10 fixedly connected to the rotating shell 9, an energizing plate 11 fixedly connected to the outside of the rotating shell 9, an energizing rod 12 fixedly connected to the bottom of the energizing plate 11, a rotating ring 13 rotatably connected to the outside of the detection column 4, the energizing rod 12 fixedly connected to the rotating ring 13, and a winding wire 14 fixedly connected to the top of the energizing plate 11, the winding wire 14 being away from the energizing plate 11. One end of the device is fixedly connected to a test pen 15. Inside the protective shell 1, multiple buckles 16 that are compatible with the test pen 15 are fixedly connected. The top of the winding shell 7 is provided with a limiting post 17, which is fixedly connected to the rotating shell 9. A limiting block 18 is slidably connected to the outside of the limiting post 17. The top of the winding shell 7 is fixedly connected to a limiting shell 19 that is compatible with the limiting block 18. Through the arrangement of the protective shell 1, sliding cover 2, rotating shell 9, spring 10, power board 11, power rod 12, detection post 4, rotating ring 13, and winding wire 14, the device can protect the tester body 3 and the test pen 15, and automatically store the test pen 15 before and after testing. This effectively solves the problem that in most battery testers, the test pen and connecting wire are often wrapped around the outside of the tester after use, which can easily damage the test pen and connecting wire during transport and make the tester dirty.

[0031] When the battery test is completed, the limiting block 18 can be pulled to disengage from the limiting shell 19. Then, the spring 10, without restraint, starts to rotate the rotating shell 9. The rotation of the rotating shell 9 pulls the power board 11 to rotate, so that the winding wire 14 is wrapped around the outside of the rotating shell 9 and the inside of the winding shell 7. Then, the test pen 15 is placed inside the buckle 16 to complete the storage of the test pen 15. Then, the sliding cover 2 can be slid to protect the tester body 3. The power rod 12 and the rotating ring 13 can ensure that the test pen 15 can be electrically connected to the tester body 3 after the rotating shell 9 is rotated. This effectively solves the problem that in most battery testers, the test pen and connecting wire are often wrapped around the outside of the tester after use, which easily damages the test pen and connecting wire during the transport of the battery tester and makes the tester easy to get dirty.

[0032] Example 2

[0033] Please see Figure 7 This utility model provides a technical solution: a portable battery tester. Sliding columns 20 are slidably connected to the interior of both sides of a protective shell 1. A movable plate 21 is fixedly connected to one end of the sliding column 20 inside the protective shell 1. The movable plate 21 is slidably connected to the protective shell 1. A circular spring 22 is sleeved on the outside of the sliding column 20. The two ends of the circular spring 22 are fixedly connected to the movable plate 21 and the protective shell 1, respectively. A test seat 23 is fixedly connected to the side of the movable plate 21. A test post 24 is fixedly connected to the outside of the test seat 23. The inside of the test post 24 has a groove adapted to the test pen 15. Through the arrangement of the sliding column 20, movable plate 21, circular spring 22, test seat 23, and test post 24, the device can clamp and fix small batteries and test them. This effectively solves the problem that when testing small batteries, the position of the small battery is easily moved, making it inconvenient to contact the test pen with the two test ends of the small battery, thus reducing the testing efficiency.

[0034] In use, pull the movable plate 21 to separate the two movable plates 21, and then place the small battery between the two movable plates 21. Then, the circular spring 22 pushes the movable plate 21 to move, thereby clamping the small battery and making the two test seats 23 contact the two detection ends of the small battery. Then, the two test pens 15 can be placed inside the test column 24 to complete the test of the small battery. This effectively solves the problem that when the tester tests small batteries, the position of the small battery is easy to change, making it inconvenient to contact the test pens with the two detection ends of the small battery, thus reducing the testing efficiency.
