[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2A folding aluminum trolley includes a trolley plate 1. A storage slot 12 is formed at the top of the trolley plate 1. Two first rotating rods 2 and two second rotating rods 13 are symmetrically arranged on both sides inside the storage slot 12. Rotating rods 3, welded to the trolley plate 1, are rotatably sleeved at the bottom of the first rotating rods 2 and the second rotating rods 13. Connecting rods 4 are provided at the top of each of the two first rotating rods 2 and the two second rotating rods 13. Rotating shafts 17, rotatably connected to the first rotating rods 2 and the second rotating rods 13 respectively, are bolted to one end of each connecting rod 4. Slots 5 are formed at the ends of the first rotating rods 2 and the second rotating rods 13 that are close to each other. Metal platforms 6 are slidably connected inside the slots 5. By sliding the metal platforms 6 into the slots 5, multiple metal platforms 6 can be stacked and secured between the first rotating rods 2 and the second rotating rods 13. This allows adjustment of the number of cargo platforms on the aluminum trolley, improving the efficiency of transporting goods.

[0029] refer to Figure 2 A magnet 14 is fixedly connected inside the slot 5, which is magnetically attracted to the metal platform 6. The magnet 14 is used to attract and fix the metal platform 6 that has slid into the slot 5, thereby preventing the metal platform 6 from slipping off automatically.

[0030] refer to Figure 1 , Figure 2 The end of the connecting rod 4 away from the rotating shaft 17 is bolted with a handle 15 that is rotatably connected to the first rotating rod 2 and the second rotating rod 13. An anti-slip sleeve 16 is fixedly fitted onto the surface of the handle 15. This increases the friction on the surface of the handle 15, making it easier to move the cart plate 1 by pushing or pulling the handle 15.

[0031] refer to Figure 1 , Figure 2 The bottom of the trolley panel 1 has a drainage hole 20. This allows water to drip out and prevents water from accumulating inside the storage tank 12.

[0032] Brief description of usage: The first rotating rod 2 and the second rotating rod 13 are rotated to stand the platform upright. Then, the metal platform 6 is aligned with the slot 5 and slid into the slot 5, allowing multiple metal platforms 6 to be stacked and secured between the first rotating rod 2 and the second rotating rod 13. Finally, goods are placed on top of the metal platforms 6 one by one. If the goods are large, the middle metal platform 6 can be slid out to increase the distance between the top and bottom metal platforms 6, thus allowing for the placement of larger goods.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 , Figure 3A folding aluminum trolley is disclosed, wherein a telescopic rod 7 is bolted inside both the first rotating rod 2 and the second rotating rod 13. Insert blocks 9, bolted to the telescopic rod 7, are slidably connected to the opposite sides of the bottom of the first rotating rod 2 and the second rotating rod 13. A spring 8, welded to the insert block 9, is sleeved on the surface of the telescopic rod 7. First insertion holes 10 and second insertion holes 11, respectively, are formed on both sides of the trolley plate 1, which are inserted into the insert blocks 9. The trolley can be rotated upright or folded by rotating the first rotating rod 2 and the second rotating rod 13, and the insert blocks 9 are inserted into the first insertion holes 10 and the second insertion holes 11 to limit and fix the first rotating rod 2 and the second rotating rod 13. This facilitates the folding and storage of the aluminum trolley, reduces the space occupied by the trolley, and improves its practicality.

[0035] refer to Figure 1 , Figure 2 Both sides of the bottom of the trolley plate 1 are bolted with casters 18, and a locking device 19 is fixedly connected to one side of the casters 18. This allows the trolley plate 1 to rotate and move by driving the casters 18, and at the same time, the trolley plate 1 can be limited by using the locking device 19 to fasten the casters 18.

[0036] refer to Figure 1 , Figure 3 The first insertion hole 10 and the second insertion hole 11 are respectively opened on both sides of the trolley plate 1 at positions aligned with the insertion block 9 after the first rotating rod 2 and the second rotating rod 13 are rotated. After the first rotating rod 2 and the rotating rod 3 are rotated and folded, the insertion block 9 can be accurately inserted into the first insertion hole 10 and the second insertion hole 11.

[0037] Brief description of usage: By rotating the first rotating rod 2 and the second rotating rod 13, they are raised from inside the storage slot 12 with the support of the rotating rod 3. At the same time, the connecting rod 4 is rotated on top of the two first rotating rods 2 or the two second rotating rods 13 using the rotating shaft 17, which provides support and reinforcement. Then, the spring force of the spring 8 drives the telescopic rod 7 to push the insert 9 outward, allowing the insert 9 to slide into the first insertion hole 10, thus limiting and fixing the first rotating rod 2 and the second rotating rod 13 after they are rotated and raised. Finally, the insert 9 can be pressed to overcome the spring force of the spring 8 and slide back out of the first insertion hole 10, allowing the first rotating rod 2 and the second rotating rod 13 to rotate in opposite directions and fold back into the storage slot 12 for storage. The spring 8 will drive the insert 9 to slide outward again, allowing the insert 9 to slide into the second insertion hole 11 to limit the first rotating rod 2 and the second rotating rod 13. When the first rotating rod 2 and the second rotating rod 13 are rotated and folded, the metal platform 6 inside the slot 5 needs to be completely slid out.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
