[0004] Since batteries are packed together in groups of 4, they are squeezed during the packing process. In addition, the cutter card is made of corrugated paper, which is relatively thick. Therefore, some unqualified products may be caused in the later operation, such as film breakage (caused by squeezing) and deformation. In addition, the box cannot be disassembled and folded, resulting in poor flexibility. Therefore, an inner box for lithium-ion battery shipping packaging is proposed to solve the above problems.

When it needs to be unfolded, the screw rod 16 is driven to rotate by rotating the turntable 17 to release the fixation of the fixing block 14. After the fixation is released, the chassis 1 is rotated again by the hinge 7. After the chassis 1 is unfolded, the protrusion 9 can be placed inside the buckle 12. The spring 13 makes the buckle 12 elastic so as to fix the protrusion 9, thereby fixing the fixing plate 1 8. After the fixing plate 1 8 is fixed, the chassis 1 can be fixed. When the top cover 1 2 and the top cover 2 3 need to be installed, the connecting plate 4 can be inserted into the top cover 2. When the pull ring 6 is released, the limit plate 18 can be reset by the elastic force of the spring 2 19. The limit plate 18 can drive the fixing rod 5 to reset by resetting. The fixing rod 5 can fix the connecting plate 4 by resetting, thereby fixing the top cover 2 3. The box body can be disassembled and folded to adjust according to on-site needs, thereby improving its flexibility.
