The EPS foam insulation box body 2 is disposed on the outside of the box bottom 1. Handrails 3 are symmetrically installed on the top side wall of the EPS foam insulation box body 2. Four sets of corner blocks 4 with equal spacing are installed on the top of the EPS foam insulation box body 2. Four sets of positioning blocks 5 with equal spacing are installed on the bottom of the box bottom 1. Two sets of limiting grooves 6 are symmetrically installed on the inner wall of the EPS foam insulation box body 2. The interior of the EPS foam insulation box body 2 is provided with... The EPS foam insulation box body 2 has multiple sets of partition bodies 7. The surface of the EPS foam insulation box body 2 is provided with multiple sets of through holes 8 at equal intervals. All through holes 8 extend through the EPS foam insulation box body 2 to its outside. Multiple sets of U-shaped blocks 9 at equal intervals are installed on the outer wall of the EPS foam insulation box body 2. Telescopic columns 11 are movably installed inside the U-shaped blocks 9. The telescopic columns 11 extend through the U-shaped blocks 9 and through holes 8 to its outside. Multiple sets of support plates 10 are provided inside the limiting grooves 6. The partition bodies 7 are all connected to the support plates 10. One end of the telescopic column 11 outside the U-shaped blocks 9 is fitted with a pull ring 13.

[0031] The other end of each telescopic column 11 is equipped with a slanted groove block 14. The surface of each telescopic column 11 inside the U-shaped block 9 is fitted with a spring body 12. One end of the spring body 12 is in contact with the U-shaped block 9, and the other end of the spring body 12 is in contact with the slanted groove block 14.

[0040] Working principle: When it is necessary to adjust the spacing between the partition bodies 7, pull the multiple sets of pull rings 13. Under the support of the U-shaped block 9, the pull rings 13 drive the telescopic column 11, spring body 12, and inclined groove block 14 to move outward, so that the support plate 10 and the groove 15 move up and down inside the limiting groove 6. When it moves to the appropriate height, release the pull rings 13. Under the elastic support of the spring body 12, the inclined groove block 14 locks the groove 15, fixing the support plate 10 and the partition body 7. When it is necessary to increase the height of the EPS foam insulation box, place the outer box on top of the EPS foam insulation box body 2. Under the support of the multiple sets of corner blocks 4, it is firmly fixed on top of the EPS foam insulation box body 2. Continue to place the partition body 7 to add items. Turn the handle 18. Under the support of the EPS foam insulation box body 2, the handle 18 moves... The rotating column 16 rotates, causing the torsion spring 20 and retaining ring 17 to rotate, disengaging the retaining ring 17 from the support column 19. The EPS foam insulation box body 2 is then flipped over. Under the movable support of the rotating shaft 24, the EPS foam insulation box body 2 drives multiple sets of second hinges 23 to rotate and move around the rotating shaft 24 to clean the interior. After cleaning, the EPS foam insulation box body 2 is flipped over in the opposite direction. Under the movable support of the second hinges 23, the EPS foam insulation box body 2 is secured to the surface of the box bottom 1. Under the elastic support of the torsion spring 20, the torsion spring 20 resets. The torsion spring 20 then drives the rotating column 16, handle 18, and retaining ring 17 to rotate and reset, locking the retaining ring 17 with the support column 19 for fixation. The baffle 21 acts as a limit, thus completing the use of the EPS foam insulation box.
