[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Therefore, this type of battery is also called a lithium metal battery. With the development of science and technology, lithium batteries have now become mainstream.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 5 A convenient quick-install lithium battery testing tool includes a synchronous connector 1, an upper boss 7 and a temperature sensor boss 8 are provided above the synchronous connector 1, and the temperature sensor boss 8 is used to install the temperature sensor. The lower end of the synchronous connector 1 is connected to the positioning plate 2 through an elastic synchronous lifting component, and a cover plate 6 is provided below the positioning plate 2. The cover plate 6 is fixedly connected to the positioning plate 2 through a boss component.

[0022] When the device is in use, it is embedded in the temperature measuring equipment. During the test, the elastic synchronous lifting component applies elastic force to the synchronous connector 1, so that the temperature sensor on the temperature sensor boss 8 is tightly fitted to the test piece to complete the test. After the test, the battery test piece can be directly taken out. Compared with the existing technology, the device completes the fixation of the temperature sensor at one time, and there is no need to specify the temperature sensor according to the test piece each time, without increasing the operating workload and no additional labor cost. In addition, the device has a simple structure, thereby increasing stability, does not require additional driving force and driving signal, is small in size, has a wide range of applications, is low in cost, and can be customized in size.

[0023] Furthermore, the elastic synchronous lifting assembly includes two satellite shafts 5 and a spring 4. The two satellite shafts 5 are respectively arranged on both sides of the positioning plate 2. The spring 4 is arranged in the middle between the positioning plate 2 and the synchronous connector 1. The satellite shaft 5 includes an axle seat 14 and a cross shaft 13. The axle seat 14 is installed on the positioning plate 2 and passes through the positioning plate 2. The cross shaft 13 is movably nested in the axle seat 14. The top of the cross shaft 13 is connected to the bottom of the synchronous connector 1. The two cross shafts 13 are connected by a steel wire 3.

[0024] The steel wire 3 connects the satellite shafts 5 at both ends (a movable groove 16 is provided on one side of the shaft seat 14, and the movable groove 16 is located below the positioning plate 2. A slot 18 is provided at the lower end of the cross shaft 13. The steel wire 3 is in a "concave" shape. Both ends of the steel wire 3 pass through the movable groove 16 and are inserted into the slot 18. When the cross shaft 13 moves downward, the two ends of the steel wire 3 move synchronously), allowing the satellite shafts 5 to rise and fall synchronously; the spring 4 applies elastic force to the synchronous connector 1, so that the temperature sensor on the temperature sensor boss 8 fits tightly against the test piece; the satellite shaft 5, when the upper boss 7 of the synchronous connector 1 is subjected to force, the satellite shaft 5 at one end is forced to sink, and the force is transmitted to the satellite shaft 5 at the other end through the steel wire 3, so that the satellite shafts 5 at both ends sink at the same time, driving the temperature sensor boss 8 of the synchronous connector 1 to sink together.

[0025] Furthermore, the boss assembly includes three lower bosses 19, which are respectively arranged on both sides and the middle of the cover plate 6, and the upper end of the lower boss 19 in the middle position passes through the positioning plate 2. One end of the spring 4 is connected to the bottom end of the synchronous connector 1, and the other end of the spring 4 is connected to the top of the positioning plate 2 and is sleeved on the outer periphery of the lower boss 19 to fix the spring 4.

[0026] Furthermore, a notch 17 is provided on one side of the lower boss 19 on both sides of the cover plate 6. The position of the notch 17 corresponds to the steel wire 3, which can avoid interference with the steel wire 3, making the structure of the device more compact.

[0027] Furthermore, the cover plate 6 is connected and fixed to the test equipment through the first hole body 10, and the lower boss 19 protrudes from the positioning plate 2 through the third hole body 11 on the positioning plate 2, thereby fixing the spring 4. The fourth hole body 12 is the wire hole for the temperature sensor, and the wire of the temperature sensor extends out of the test equipment through this hole. The second hole body 9 is used to fix the axle seat 14, and the satellite axis 5 has a fifth hole body 15 for connecting with the positioning plate 2.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
