DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-2A battery flame extinguishing test device, wherein an opening 11 is provided on the top surface of a test box 1, a door 13 is provided on one side of the test box 1, and a visual window 14 is provided on the door 13. The visual window 14 is made of transparent glass or a transparent acrylic plate, and the visual window 14 is used to watch and record the fire of the battery and the fire extinguishing of the flame extinguishing device. A test platform for fixing a battery 4 is provided in the test box 1, and the test platform includes a bracket 2, and a groove 21 is provided on the upper surface of the bracket 2. A fixing protrusion 12 is provided on the bottom of the test box 1, and a fixing groove 22 is provided on the bracket 2 to cooperate with the fixing protrusion 12. The cooperation between the fixing protrusion 12 and the fixing groove 22 can prevent the bracket from moving in the horizontal direction. A needle 3 can be provided on the opening 11, and a flame extinguishing device 5 can be fixed on the top of the inside of the test box 1. The flame extinguishing device 5 used in this embodiment is a flame extinguishing patch made of flame extinguishing microcapsules. It can be understood that other flame extinguishing devices are also possible, such as a flame extinguishing box. The test device's needle penetrates the battery placed on the test platform, causing the battery to generate flames to verify the flame extinguishing device's effectiveness. The test device can be used to continuously improve the composition ratio of the flame extinguishing device and find the most suitable flame extinguishing product for battery fire extinguishing.

[0023] Furthermore, a flat plate 31 larger than the opening 11 is provided on the top of the puncture needle 3. The flat plate 31 can not only prevent the puncture needle 3 from completely entering the test box 1, but also increase the force-bearing area of ​​the external force.
