Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics and warehousing equipment technology, specifically a foldable storage cage. Background Technology
[0002] Storage cages, also known as warehouse cages or butterfly cages, are a type of standardized logistics container commonly used in warehousing and logistics. They offer advantages such as fixed storage capacity, neat stacking, clear visibility of stored items, and ease of inventory counting, while also improving the effective utilization of warehouse space. Storage cages are made of high-strength welded steel wire, reinforced at the bottom with U-shaped channel steel or rectangular tubes, providing a high load-bearing capacity. They can be stacked three to four layers high and used in conjunction with forklifts, pallet jacks, and other equipment. They are widely used in workshops, warehouses, and transportation processes in industries such as machining, automotive parts, food, and e-commerce.
[0003] While the mainstream folding storage cages on the market can achieve folding and storage, they still have the following drawbacks: the folding mechanism is complex, mostly using exposed hinges or bolts, requiring multiple people to work together, which is time-consuming and labor-intensive; the locking method between the side panels is simple, relying only on pins or buckles for fixation, which can easily loosen due to bumps during long-distance transportation, causing goods to scatter; the bottom plate reinforcement structure is simple, which is prone to plastic deformation under heavy loads, affecting stacking stability; the casters lack anti-slip and brake linkage design, making them prone to displacement on slopes or smooth surfaces, posing a safety hazard; stacking positioning relies only on simple interlocking between the wheels, lacking a precise positioning structure, which can easily lead to misalignment and tilting after multiple layers are stacked.

The bottom cross-shaped horizontal reinforcing rods 20 and vertical reinforcing rods 19 of the base plate, as well as the base rods 5, are all made of high-strength steel, which increases the load-bearing capacity and does not deform after long-term use.
[0020] As an example of this utility model, the caster wheel 13 is made of polyurethane with a braking function and is fixed to the caster base plate 17 by bolts. It is quiet and wear-resistant. The brake pedal 16 is linked to the anti-slip pad 15, so it does not slip when parked on a slope, which improves the safety factor. The stacking rack 6 is welded to the bottom edge of the left side plate 1 and the right side plate 23. The U-shaped groove 18 is precisely fitted with the caster wheel 13 of another storage cage to achieve accurate positioning. The overall tilt of the four-layer stack is reduced, and the utilization rate of storage space is improved.
[0021] The working principle of this utility model is as follows: When in use, push the foldable storage cage to the working position, step on the fixed pedal 16, brake and lock the universal wheels 13, and ensure the anti-slip mat 15 is firmly attached to the ground to prevent slippage; pull the latch handle 12 outward to disengage the latch rod 11 from the latch hole 10, releasing the front side panel 21 from locking; stand the front side panel 21 upright and release it, and the latch rod 11 automatically springs back and inserts into the latch hole 10 to complete the locking; stand the left side panel 1 and right side panel 23 upright in the same way, and hook them to the rear side panel 22 with the fixing hook 7; the base rods 5 and support rods 2 around the bottom plate 14 form a rigid frame, and the horizontal reinforcing rods 20 and vertical reinforcing rods 19 of the bottom plate provide 1.5 tons of support. Load-bearing capacity; after the goods are loaded, if stacking is required, the casters 13 of the upper cage are aligned with the U-shaped grooves 18 of the lower stacking rack 6 and placed vertically to achieve precise positioning of four layers; when the empty cage is recycled, the pin rod 11 is pulled out and the fixing hook 7 is released, the left side plate 1 and the right side plate 23 are laid down in sequence, and then the upper side plate 9 is folded down and aligned with the lower side plate 8, the overall height is halved, and the brake can be released to push it away. The return transport vehicle can carry 280 units, and the volume is reduced by 70%.
[0022] Although the present invention 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.
