Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, in particular to a clamp for lithium battery detection. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. After the production of lithium batteries, it is usually necessary to use an electric pen or an electric meter to detect whether the lithium battery has a discharge function to facilitate the normal use of the lithium battery.

[0003] During use, most of the existing lithium battery testing clamps can only clamp and test one lithium battery. However, when it is necessary to clamp a battery pack consisting of multiple lithium batteries, other clamps are needed to perform the clamping work. As a result, the lithium battery testing clamps are less versatile and cannot meet the function of clamping lithium battery packs.

[0004] Therefore, it is necessary to provide a lithium battery testing fixture to solve the above technical problems. Utility Model Content

[0029] Reference Figure 1-4 The utility model provides a lithium battery detection fixture: it includes a base 1, a support column 2 is fixedly connected to the top of the base 1, a circular plate 3 is rotatably connected to the outer surface of the support column 2, a plurality of slots 4 are provided on the circular plate 3, and two fixing plates 5 are fixedly connected to the top of the circular plate 3, threaded rods 6 are passed through and threadedly connected to the two fixing plates 5, one end of the threaded rod 6 is fixedly connected to a device plate 7, and the other end of the threaded rod 6 is fixedly connected to a knob 11, a slide groove 8 is provided on the top of the device plate 7, a slider 9 is movably connected inside the slide groove 8, a clamping plate 10 is fixedly connected to one side of the slider 9, and a rubber pad 23 is provided on one side of the clamping plate 10, through the setting of the rubber pad 23, the friction between the clamping plate 10 and the lithium battery can be increased when clamping the lithium battery, so as to improve the stability in the process of detecting the lithium battery, a limited position component is provided on the device plate 7, and a clamping component for fixing the disc is provided on the top of the base 1.

[0030] The limiting assembly includes slots 12 opened on both sides of the device plate 7, and the interiors of the two slots 12 are rotatably connected with rotating rods 13, and one end of the two rotating rods 13 is fixedly connected to a rotating plate 14. An opening 15 is opened on the rotating plate 14, and a spring 16 is arranged inside the opening 15. The two springs 16 are connected by an abutment plate 17, and the two sides of the abutment plate 17 are respectively slidably connected to the inner walls of the two openings 15. Through the setting of the limiting assembly, the two abutment plates 17 can be respectively abutted against the tops of the two device plates 7, thereby fixing the slider 9 inside the slide groove 8 to prevent the slider 9 from sliding out of the slide groove 8.

[0031] The clamping assembly includes a support plate 18 fixedly connected to the top of the base 1, a slide rod 19 passing through and slidably connected to the support plate 18, one end of the slide rod 19 is fixedly connected to a clamping block 20, and the other end of the slide rod 19 is fixedly connected to a pull plate 21, and a spring 22 is sleeved on one side of the support plate 18 and on the outer surface of the slide rod 19. Through the setting of the clamping assembly, the circular plate 3 can be limited and fixed with the cooperation of the card slot 4 to prevent the circular plate 3 from rotating during the detection process and affecting the detection work.

[0032] Working principle: when in use, the two knobs 11 are turned to drive the two threaded rods 6 to rotate respectively, so that the two clamping plates 10 move to the side away from each other, and then the lithium battery to be tested is placed on the circular plate 3 and located between the two clamping plates 10, and then the two knobs 11 are turned again to make the two clamping plates 10 move to the opposite side, so that the lithium battery placed on the circular plate 3 is clamped and the testing work is carried out.
