[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a lithium battery storage device, including a cabinet 1, a door panel 2 provided on the inner wall of the cabinet 1, a storage rack 3 provided inside the cabinet 1, a hollow cylinder 4 fixedly connected inside the cabinet 1, a U-shaped rod 5 slidably connected inside the hollow cylinder 4, a disc 6 fixedly connected to the outer wall of the U-shaped rod 5, the outer wall of the disc 6 slidably connected to the inner wall of the hollow cylinder 4, a spring 7 fixedly connected to the outer wall of the disc 6, the outer wall of the spring 7 fixedly connected to the inner wall of the hollow cylinder 4, a limit rod 8 fixedly connected to the left outer wall of the U-shaped rod 5, the outer wall of the limit rod 8 slidably connected to the inside of the storage rack 3, a protective pad 9 provided on the inner wall of the cabinet 1, and an opening and closing assembly provided inside the cabinet 1;

[0025] Specifically, a soft pad is provided on the outer wall of the door panel 2, which works in conjunction with the protective pad 9 provided on the inner wall of the cabinet 1. The soft pad and the protective pad 9 are elastic to protect the lithium battery on the surface of the shelf 3 and reduce hard impacts on the lithium battery. Holes are provided on both sides of the cabinet 1 to dissipate heat from the inside of the cabinet 1. Without external force driving the U-shaped rod 5, the elastic force of the spring 7 pushes the disc 6 and the U-shaped rod 5 to move to the left, thereby causing the limiting rod 8 to slide into the interior of the shelf 3 for limiting. Through the cooperation between the hollow cylinder 4, the U-shaped rod 5 and the disc 6, the shelf 3 is prevented from shaking after being limited.

[0026] Reference Figure 1 The opening and closing assembly includes a hinge 10, the outer wall of the hinge 10 is fixedly connected to the inside of the cabinet 1, and the front outer wall of the hinge 10 is fixedly connected to the inside of the door panel 2;

[0027] Specifically, one side of the hinge 10 is fixed to the cabinet 1, and the other side of the hinge 10 is fixed to the door panel 2, so that the door panel 2 rotates around the pivot of the hinge 10, thereby opening or closing the cabinet 1.

[0028] Reference Figure 2 A fixing block 11 is fixedly connected to the outer wall of the door panel 2, and a hollow block 12 is slidably connected inside the fixing block 11. The outer wall of the hollow block 12 is fixedly connected to the outer wall of the cabinet 1.

[0029] Specifically, by matching the interior of the fixing block 11 with the outer wall of the hollow block 12, the fixing block 11 and the hollow block 12 can fit together, thereby limiting the rotation of the door panel 2.

[0030] Reference Figure 2 and Figure 4 A sliding rod 13 is slidably connected inside the hollow block 12. A U-shaped block 14 is fixedly connected to the outer wall of the sliding rod 13, and the outer wall of the U-shaped block 14 is located inside the hollow block 12. A triangular block 15 is slidably connected to the outer wall of the U-shaped block 14, and a limiting block 16 is fixedly connected to the outer wall of the triangular block 15. The outer wall of the triangular block 15 is slidably connected to the inner wall of the hollow block 12. The outer wall of the limiting block 16 penetrates the interior of the hollow block 12 and is slidably connected to the interior of the fixed block 11. A telescopic rod 17 is fixedly connected to the lower surface of the limiting block 16, and the bottom end of the telescopic rod 17 is fixedly connected to the interior of the hollow block 12. A second spring 18 is provided on the outer wall of the telescopic rod 17. One end of the second spring 18 is fixedly connected to the lower surface of the limiting block 16, and the other end of the second spring 18 is fixedly connected to the inner wall of the hollow block 12.

[0031] Specifically, the rear side of the U-shaped block 14 contacts the inner wall of the U-shaped block 14, and the front side of the U-shaped block 14 contacts the triangular block 15. The movement of the slide rod 13 is offset and limited by the interior of the hollow block 12, thereby limiting the movement of the U-shaped block 14. The inclined surface of the U-shaped block 14 matches the inclined surface of the triangular block 15, which facilitates the transmission of the U-shaped block 14 to the triangular block 15. The movement of the triangular block 15 is limited by the interior of the hollow block 12. Without external force driving the slide rod 13, the elastic force of the second spring 18 pushes the limiting block 16 upward, providing support for the limiting block 16 inside the fixed block 11. The telescopic rod 17 is used to prevent the second spring 18 from deforming excessively when it is squeezed and stretched.

[0032] Working principle: When using this device, push the slide bar 13 to move the U-shaped block 14 forward. Utilize the cooperation between the U-shaped block 14 and the inclined surface of the triangular block 15 to push the triangular block 15 downward, causing the limiting block 16 to move downward inside the hollow block 12, compressing the telescopic rod 17 and squeezing the second spring 18. When the limiting block 16 slides out of the fixed block 11, it no longer limits the fixed block 11, making it convenient to pull the door panel 2 to open the cabinet 1 under the action of the hinge 10. Place the lithium batteries to be stored on the upper surface of the shelf 3, and then rotate the door panel 2 to close the cabinet 1, aligning the fixed block 11 with the hollow block 12. Release the slide bar 13, and under the elastic force of the second spring 18, the limiting block 16 slides into the fixed block 11 for limiting, thereby limiting the closing of the door panel 2.

[0033] When maintenance is required on the placement rack 3, pull the U-shaped rod 5, causing the disc 6 to slide to the right on the inner wall of the hollow cylinder 4, thereby compressing the spring 7. The U-shaped rod 5 then moves the limiting rod 8 to the right, causing the limiting rod 8 to slide out of the placement rack 3 and no longer limit the placement rack 3. This makes it easy to remove the placement rack 3 for maintenance or replacement. During use, this device not only allows for quick installation and disassembly of the placement rack 3, facilitating the replacement of different placement racks 3 or the maintenance of the placement rack 3, but also limits or releases the opening and closing of the door panel 2, improving operational safety.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
