[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0023] See also Figures 1 to 4 In this embodiment, a sodium ion battery test fixture is provided, including a base 1, a detection mechanism 2 is installed above the base 1, a plurality of test lamps 3 are installed on the base 1, the detection mechanism 2 includes a placement groove 21, a movable plate 24 is slidably connected inside the placement groove 21, a fixed plate 23 is fixedly connected to one end of the placement groove 21, and the movable plate 24 and the fixed plate 23 are both electrically connected to the test lamp 3;

[0024] A push rod 28 is rotatably connected to the lower side of the placement groove 21 , one end of the push rod 28 is bent and obliquely upward and located inside the placement groove 21 , and the other end of the push rod 28 is bent and obliquely downward and located below the placement groove 21 , and the upper end of the push rod 28 is located on one side of the movable plate 24 .

[0025] Before use, the test lamp 3 is connected in parallel with the movable plate 24 and the fixed plate 23. When in use, the battery is placed inside the placement slot 21. When there is no fault inside the lithium battery, the current of the lithium battery flows into the test lamp 3 through the movable plate 24 or the fixed plate 23, thereby lighting up multiple test lamps 3. When the test lamp 3 on one side is damaged, the test lamp 3 on the other side can still remain lit, so that inaccurate testing will not occur due to damage to a single test lamp 3.

[0026] When taking out the tested lithium battery from the placement groove 21, the movable plate 24 is moved away, and one end of the movable plate 24 pushes one end of the push rod 28 to rotate, and the other end of the push rod 28 rotates and extends into the placement groove 21 to push out the battery inside the placement groove 21 (a groove is opened inside the placement groove 21 for the push rod 28 to rotate), so as to facilitate the user's use.

[0027] In further embodiments, see Figure 2 The two ends of the fixed plate 23 are fixedly connected with the wiring board 1 231, and the two ends of the movable plate 24 are fixedly connected with the wiring board 2 241. The fixed plate 23 and the movable plate 24 are electrically connected to the test lamp 3 through the wiring board 1 231 and the wiring board 2 241. The wiring board 1 231 and the wiring board 2 241 are connected to the test lamp 3 through wires, and multiple test lamps 3 can be connected in parallel through multiple wiring boards 1 231 and multiple wiring boards 2 241.

[0028] In further embodiments, see Figure 2The two sides of the placement slot 21 are fixedly connected with fixing rods 26, and the fixing rods 26 pass through the second wiring board 241. A spring 27 is arranged outside the fixing rod 26, and one end of the spring 27 is fixedly connected to the second wiring board 241, and the other end of the spring 27 is fixedly connected to one end of the fixing rod 26. The second wiring board 241 is pulled close to one end of the fixing rod 26 by the spring 27, so that the movable plate 24 is close to the fixed plate 23, so that when the battery is placed in the placement slot 21, the battery can be pressed against the fixed plate 23 by the movable plate 24, so as to maintain a stable connection.

[0029] In a further embodiment, the fixing rod 26, the spring 27 and the placement slot 21 are all made of non-conductive material.

[0030] In further embodiments, see Figures 2-3 The upper end of the movable plate 24 is provided with an inclined surface, and the lower end of the inclined surface faces between the movable plate 24 and the fixed plate 23. The inclined surface facilitates the insertion of one end of the battery into the placement slot 21 near the end of the movable plate 24, and when one end of the battery is tilted from the end near the movable plate 24, it is also convenient for the user to take it out.

[0031] In further embodiments, see Figures 2-3 One end of the movable plate 24 is fixedly connected with a pull ring 25, which is made of a non-conductive material. The pull ring 25 facilitates the user to pull and move the movable plate 24.

[0032] In further embodiments, see Figure 2 A connecting plate 22 is fixedly connected below the placement groove 21, and the lower end of the connecting plate 22 is fixedly connected to the base 1. The distance between the placement groove 21 and the base 1 is increased by the connecting plate 22, so that the space for accommodating the lower end of the push rod 28 can be provided.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
