[0036] It should be noted that the side of the fixed card seat 501 is welded and fixed to the bottom frame 1, the rotating pin 202 is inserted into the inner cavity of the fixed card seat 501, and the pressing plate 502 is tightened and fixed with bolts, thereby restricting the rotating pin 202 in the inner cavity of the fixed card seat 501, so that the side frame 201 can rotate around the rotating pin 202;

[0037] The top of the bottom frame 1 and the sides of the side frame 201 are both provided with a buffer pad 6. The buffer pad 6 is made of EVA material and glued. It is used to ensure that the surface of the steel spring product is not bumped or scratched when in contact with the packaging rack during transportation, and plays a role of buffer protection. The bottom of the bottom frame 1 is provided with a foot pad 7. The foot pad 7 and the bottom frame 1 are interlaced and fixed by multiple bolts. The foot pad 7 is made of steel plate and polyurethane vulcanized. The main function is to protect the packaging box from wear and tear on the ground. The bottom of the foot pad 7 is provided with a stacking hole for the stacking corner 302 to be inserted, so that multiple packaging boxes can be stacked and fixed;

[0038] Specifically, a V-shaped groove is welded on the top of the bottom frame 1, which is a structure for limiting the stacking of the upper package during the stacking process after the package is folded. A fork opening for a forklift in the horizontal direction is reserved at the bottom of the package to prevent the package box and the fork from sliding relative to each other and tipping over. Hook plates for lifting the package are symmetrically welded on both sides of the bottom frame 1.

[0039] In actual use, a folding leg assembly 3 and a side frame assembly 2 are arranged on the top of the bottom frame 1, which together limit the steel spring placed on the top of the bottom frame 1, wherein the support rod member 4 arranged at the bottom of the folding leg assembly 3 can be adjusted to squeeze and fix the loaded steel spring to meet the packaging and fixing requirements of steel springs of different rail vehicle models, thereby avoiding the steel spring being loosely fixed on the bottom frame 1, causing the steel spring product to shake, and the folding leg assembly 3 and the side frame assembly 2 of the package can be hinged and flipped, and after the steel spring is unloaded, it can be flipped and folded, which is convenient for the staff to stack multiple packages and saves the loading space of the recycling transportation of the packaging box.
