One end of the elastic member 52 is fixedly connected to the locking block 51, and the other end is fixedly connected to the sliding shaft 4. When the partition plate 3 is adjusted, the operator pushes the partition plate 3 so that the partition plate 3 drives the sliding shaft 4 to slide along the slide groove 11. During the sliding process, the sliding shaft 4 drives the locking block 51 to slide along the slide groove 11. The locking block 51 compresses the elastic member 52. When the partition plate 3 slides to the desired position, the partition plate 3 is no longer pushed. At this time, the elastic member 52 releases the elastic restoring force, and the elastic member 52 drives the locking block 51 to slide into the locking groove 12. The locking block 51 is locked with the locking groove 12 to fix the position of the partition plate 3.

Both sliding racks 73 are meshed with the rotating gear 72. One sliding rack 73 is fixedly connected to one sliding plate 32. The rotating gear 72 is used to drive the two sliding racks 73 to slide in the direction of approaching or moving away from each other. The operating rod is rotated to drive the rotating gear 72 to rotate. When the rotating gear 72 rotates, the two sliding racks 73 are driven to slide in the direction of approaching or moving away from each other at the same time. The two sliding racks 73 respectively drive the two sliding plates 32 to slide in the direction of approaching or moving away from each other.

[0046] The implementation principle of the lithium-ion battery safety isolation transfer box of the present invention is as follows: when the lithium-ion battery needs to be transferred, the lithium-ion battery is first stored, and when stored, the driving member 9 is started, and the driving member 9 drives the transfer box cover 2 to rotate, so that the transfer box cover 2 is opened from the transfer box body 1; Then, the partition plate 3 is adjusted, and the operator pushes the partition plate 3, so that the partition plate 3 drives the rotating shaft 6 and the sliding shaft 4 to slide along the sliding groove 11. During the sliding process, the sliding shaft 4 drives the locking block 51 to slide along the sliding groove 11, and the locking block 51 compresses the elastic member 52. When the partition plate 3 slides to the desired position, the partition plate 3 is no longer pushed. At this time, the elastic member 52 releases the elastic restoring force, and the elastic member 52 drives the locking block 51 to slide into the locking groove 12. The locking block 51 is locked with the locking groove 12 to fix the position of the partition plate 3; Then adjust the width of the partition plate 3. When adjusting, first rotate the locking piece, and the locking piece slides out from the sliding shaft 4. At this time, the locking piece no longer locks the rotating shaft 6. Then rotate the partition plate 3. After the rotation of the partition plate 3 is completed, rotate the locking piece, and the locking piece is screwed into the sliding shaft 4, and squeezes and locks the rotating shaft 6 to complete the rotation positioning of the partition plate 3. Then, the operating lever is rotated to drive the rotating gear 72 to rotate. When the rotating gear 72 rotates, it drives the two sliding racks 73 to slide in the directions of approaching or moving away from each other at the same time. The two sliding racks 73 respectively drive the two sliding plates 32 to slide in the directions of approaching or moving away from each other. When the sliding adjustment of the sliding plate 32 is completed, the operating lever is no longer rotated. At this time, the lithium-ion battery is placed in the cavity formed by the transfer box 1 and the partition plate 3 to store the lithium-ion battery. After the storage is completed, the driving part 9 is started to drive the transfer box cover 2 to rotate, so that the transfer box cover 2 closes the transfer box 1, and then the lithium-ion battery can be transported through the moving unit.
