It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1 Please see Figures 1-3 This embodiment provides a foldable storage rack for an airline catering cart, comprising a frame body and a shelf 3. The frame body includes two opposing side frames 1 and two first crossbars 2 located between the two side frames 1; the side frames 1 have a rectangular frame structure, including two uprights 11 and two second crossbars 12 fixed between the two uprights 11, the two second crossbars 12 being respectively connected to the upper and lower ends of the uprights 11; the two ends of the first crossbars 2 are provided with first loops 21, and the uprights 11 of the two side frames 1 are rotatably disposed within the first loops 21 corresponding to the first crossbars 2.

[0031] A third horizontal bar 13 is fixed between the two uprights 11 of one side frame 1. The shelf 3 includes a fourth horizontal bar 31 arranged parallel to the third horizontal bar 13 and four first connecting rods 32 arranged at intervals and parallel to each other. The first connecting rods 32 and the fourth horizontal bar 31 are perpendicular to each other. One end of the first connecting rod 32 is fixed to the fourth horizontal bar 31, and the other end of the connecting rod is provided with a second ring 33, which is rotatably sleeved on the outside of the third horizontal bar 13. The length of the fourth horizontal bar 31 is greater than the length of the third horizontal bar 13. The height of the third horizontal bar 13 is slightly higher than the height of the first horizontal bar 2, which is located at the higher position.

[0032] The upright 11 is provided with a first limiting member that cooperates with the first ring 21 to limit the longitudinal sliding of the first ring 21 on the upright 11. The setting of the first limiting member ensures that the side frame 1 is fixed in position within the frame body, prevents the two side frames 1 from moving up and down during use, and ensures the structural stability of the shelf. The first limiting member includes a reinforcing rod 4 that is laterally connected between the two uprights 11, and one end of the first ring 21 abuts against the reinforcing rod 4. The reinforcing rod 4 not only strengthens the structural strength and stability of the side frame 1, but also limits the longitudinal displacement of the first ring 21.

[0033] The second crossbar 12 is covered with a soft sleeve 5. The soft sleeve 5 increases the friction between the second crossbar 12 and the airline catering cart, preventing the shelf from shaking during use. It also provides protection, avoiding wear and noise caused by direct metal-to-metal contact, extending the shelf's lifespan, and improving user comfort.

[0034] When using the foldable storage rack on this airline's catering cart, please refer to... Figure 1The frame body is unfolded, with the two side frames 1 positioned at each end. The first crossbar 2 is perpendicular to the side frames 1, forming a rectangular frame structure. Then, the shelf 3 is flipped using the second loop 33, allowing it to rest horizontally on the two second crossbars 12, forming a stable storage platform. (Reference) Figure 3 The entire frame is mounted on the airline-style catering cart, and the gaps between the first connecting rods 32 can hold wine bottles, achieving multi-functional use of space. For storage, refer to... Figure 2 Flip the shelf 3 so that it overlaps with the side shelf 1, and then bring the two side shelves 1 together in the middle so that the entire shelf is folded into a flat structure for easy storage and transportation.

[0035] Example 2 Please see Figures 4-6 This embodiment provides a foldable storage rack for an airline catering cart, comprising a frame body and a shelf 3. The frame body includes two opposing side frames 1 and two first crossbars 2 located between the two side frames 1; the side frames 1 have a rectangular frame structure, including two uprights 11 and two second crossbars 12 fixed between the two uprights 11, the two second crossbars 12 being respectively connected to the upper and lower ends of the uprights 11; the two ends of the first crossbars 2 are provided with first loops 21, and the uprights 11 of the two side frames 1 are rotatably disposed within the first loops 21 corresponding to the first crossbars 2.

[0036] The shelf 3 includes two fifth crossbars 34 perpendicular to the first crossbar 2, and two spaced-apart second connecting rods 35 between adjacent fifth crossbars 34. One end of each fifth crossbar 34 has a third ring 36, which rotatably fits around the first crossbar 2. The length of each fifth crossbar 34 is greater than the length of the second crossbar 12, and the other end of one of the fifth crossbars 34 has a hook 341 that can overlap the first crossbar 2. This structural design allows the shelf 3 to be stably supported on the frame body in its unfolded state, preventing it from swaying or folding during use.

[0037] Furthermore, the first crossbar 2 is also provided with a second limiting member that cooperates with the third ring 36 to limit the sliding of the third ring 36 on the first crossbar 2. The setting of the second limiting member can prevent the shelf 3 from moving laterally during use, thereby improving the stability and safety of the shelf.

[0038] When using the foldable storage rack on this airline's catering cart, please refer to... Figure 4 The frame is unfolded so that the two side shelves 1 are located at both ends, with the first crossbar 2 perpendicular to the side shelves 1, forming a rectangular frame structure. Then, the shelf 3 is flipped horizontally onto the two second crossbars 12 via the third ring 36, forming a stable storage platform. When storage is needed, such as... Figure 5 As shown, first flip shelf 3 so that it overlaps with side shelf 1; as Figure 6 As shown, the two side shelves 1 are then brought together to the middle, so that the entire shelf is folded into a flat structure for easy storage and transportation.

[0039] This foldable design allows the airline catering cart's storage rack to occupy minimal space when not in use, while quickly unfolding into a stable storage platform when needed, making it ideal for the space-constrained environment of airline catering carts. Furthermore, various limiting mechanisms ensure the stability and safety of the storage rack in its unfolded state, enabling it to reliably hold meals and supplies.
