[0011] Preferably, the lower ends of the front frame and the rear frame are respectively provided with wheel frames, and wheels are installed in the wheel frames.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0013] This utility model improves the load-bearing capacity of the chassis through the design of a double-layer folding chassis assembly, making it sturdy and durable. Even when carrying heavy loads for a long time, there is no need to worry about the chassis deforming or being damaged. Furthermore, the side frames on both sides of the chassis are eliminated, allowing for direct handling of items from these sides during loading and unloading, which is more labor-saving. Especially for larger or irregularly shaped items, it is not limited by the chassis capacity and can be placed and transported flexibly to meet more loading needs, making it convenient to use.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a side-opening folding trolley includes a front frame 1 and a rear frame 2. The upper ends of the front frame 1 and the rear frame 2 are respectively formed with mounting posts 3. The sides of the mounting posts 3 are provided with fixing holes 4. In actual use, a cloth cover can be installed on the frame for use. The cloth cover is sleeved on the outer periphery of the mounting post 3 through the sleeves on the corners and fixedly connected by fasteners.

[0023] The inner walls of the front frame 1 and the rear frame 2 are respectively provided with side hinges 5. A double-layer folding base frame assembly 6 is connected between the front frame 1 and the rear frame 2 so that it can be folded and stored when not in use to reduce the space occupied.

[0024] The double-layer folding base frame assembly 6 includes an upper base frame 7, a lower base frame 8 located below the upper base frame 7, an upper base frame 9, a lower base frame 10 located below the upper base frame 9, an inner hinge 11, and an outer hinge 12 rotatably connected thereto. One end of the upper base frame 7 and the lower base frame 8 are respectively connected to the side hinge 5, and the other end of the upper base frame 7 and the lower base frame 8 are respectively connected to the inner hinge 11. One end of the upper base frame 9 and the lower base frame 10 are respectively connected to the side hinge 5, and the other end of the upper base frame 9 and the lower base frame 10 are respectively connected to the outer hinge 12.

[0025] This utility model improves the load-bearing capacity of the chassis through the design of a double-layer folding chassis assembly, making it sturdy and durable. Even when carrying heavy loads for a long time, there is no need to worry about the chassis deforming or being damaged. Furthermore, the side frames on both sides of the chassis are eliminated, allowing for direct handling of items from these sides during loading and unloading, which is more labor-saving. Especially for larger or irregularly shaped items, it is not limited by the chassis capacity and can be placed and transported flexibly to meet more loading needs, making it convenient to use.

[0026] The upper base frame 7 and the upper base frame 9 are internally connected with several transverse reinforcing rods 13 to improve the connection strength and load-bearing capacity of the upper base frame.

[0027] The upper base frame 7 is equipped with a limiting member 14 on its side. One end of the limiting member 14 is rotatably connected to the upper base frame 7. The upper side of the other end of the limiting member 14 is formed with a lever lug 15, and the lower side of the other end of the limiting member 14 is provided with a slot 16. The inner hinge member 11 or the outer hinge member 12 is provided with a locking post 17 that cooperates with the slot 16. After the trolley is actually unfolded, the limiting member 14 can be rotated to make its slot 16 lock onto the outer periphery of the locking post 17, thereby fixing the base frame, restricting the rotation and folding of the base frame, and keeping it in the unfolded state for use.

[0028] The inner hinge 11 and the outer hinge 12 are formed with a limiting wall 18 at their upper ends, and a rotation opening 19 is provided at their lower ends. The inner hinge 11 and the outer hinge 12 are formed with an abutment platform 20 at their close ends. When in the unfolded state, the inner hinge 11 and the outer hinge 12 abut against each other through the abutment platform 20, thereby maintaining a horizontal and lateral state.

[0029] The upper end of the side hinge component 5 is provided with a rotation opening 21, and the lower end of the side hinge component 5 is formed with a limiting wall 22 for the base frame to abut against when it is unfolded.

[0030] The lower ends of the front frame 1 and the rear frame 2 are respectively provided with wheel frames 23, and wheels 24 are installed in the wheel frames 23.
