[0024] See also Figure 1-4 ,

[0025] Embodiment 1: A trolley with high safety comprises a U-shaped bracket 1, a pedal storage assembly 2 is provided at the bottom of the U-shaped bracket 1, two rotating sleeves 3 are rotatably provided on both sides of the bottom end of the U-shaped bracket 1, and universal wheels 4 are installed on the sides of the rotating sleeves 3. Two side support columns 5 are symmetrically provided on the sides of the U-shaped bracket 1, and the ends of the side support columns 5 are rotatably connected to a rotating connecting plate 6, and the sides of the rotating connecting plate 6 are connected to the U-shaped bracket 1.

[0026] The two side support columns 5 are connected by two supporting connecting rods 7. Three limiting connecting rods 8 are evenly arranged between the U-shaped brackets 1. The sides of the limiting connecting rods 8 are provided with support plates 9. The limiting connecting rods 8 pass through the sides of the support plates 9. The sides of each support plate 9 are connected by a rotatable side hinged rod 10. The side of the side hinged rod 10 is rotatably connected to the hinged support rod 11, and the end of the hinged support rod 11 is rotatably connected to the side of the side support column 5.

[0027] The pedal storage assembly 2 includes a bottom pedal 201 arranged on the side of the bottom end of the U-shaped bracket 1, and two rotating connecting seats 202 are symmetrically arranged at the end of the bottom pedal 201. The bottom end of the U-shaped bracket 1 is inserted into the rotating connecting seat 202, and the bottom end of the U-shaped bracket 1 is rotatably connected to the rotating connecting seat 202 through a rotating pin 203 inserted through it. Two storage grooves 204 are symmetrically opened on the side of the bottom pedal 201, and a rotating connecting block 205 is rotatably set at the end of the storage groove 204.

[0028] A connecting screw 206 is provided on the side of the rotating connecting block 205, and a fixing nut 207 is sleeved on the connecting screw 206. A bottom opening 208 is provided at the bottom end of the U-shaped bracket 1. A fastening baffle 12 is rotatably provided on the side of the top support plate 9. A fastening screw hole 13 is provided in the middle of the fastening baffle 12, and a fastening bolt 14 is inserted into the fastening screw hole 13. A fixing socket 15 is provided in the middle of the top support connecting rod 7, and the end of the fastening bolt 14 extends into the fixing socket 15.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that an anti-slip pad is provided on the top of the U-shaped bracket 1 .

[0030] The friction between the user's hand and the top of the U-shaped bracket 1 is increased, making it easier for the user to push the U-shaped bracket 1.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the opening length of the bottom opening 208 is greater than the length of the connecting screw 206 .

[0032] This allows the connecting screw 206 to easily penetrate the middle of the bottom opening 208 after rotating in the receiving groove 204 .

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that the diameter of the fixing nut 207 is larger than the opening diameter of the bottom opening 208 .

[0034] The fixing nut 207 is sleeved on the connecting screw 206 , so as to fasten the connecting screw 206 passing through the bottom opening 208 and the U-shaped bracket 1 .

[0035] In this embodiment, the existing ladder is relatively heavy, which makes it difficult for people to move it, and lacks a corresponding safety fastening mechanism, thereby posing certain safety hazards and being inconvenient for users to use.

[0036] In summary, in specific implementation, when the user needs to use the device to take goods from the shelf, the user first needs to separate the side support column 5 and the U-shaped bracket 1 to form a stable triangular shape standing on the ground. When the side support column 5 and the U-shaped bracket 1 are separated, the support plate 9 rotated on the limit connecting rod 8 is pulled by the side support column 5 on the hinged support rod 11, so that the hinged support rod 11 can pull the side hinged rod 10, and then the support plate 9 can be unfolded.

[0037] Then, the user rotates the bottom pedal 201 so that the bottom pedal 201 is laid flat on the ground. When the user needs to store the bottom pedal 201, the user needs to fold the bottom pedal 201 at the bottom of the U-shaped bracket 1, and rotate the connecting screw 206 so that the connecting screw 206 can pass through the bottom opening 208 when the bottom pedal 201 is close to the bottom of the U-shaped bracket 1. Then, a fixing nut 207 is installed on the end of the connecting screw 206, and the bottom pedal 201 can be stably fixed to the bottom of the U-shaped bracket 1, so that when the user pushes the U-shaped bracket 1, the pedal storage assembly 2 will not shake and affect the movement, and the bottom of the U-shaped bracket 1 is provided with a universal wheel 4, and the rotating sleeve 3 connected to the side of the universal wheel 4 can rotate, making it more convenient for the user to push the device.

[0038] When the support plate 9 is unfolded, a fastening baffle 12 is provided on the side of the support plate 9 set at the top. By rotating the fastening baffle 12 and inserting the fastening bolt 14 into the fastening screw hole 13, the end of the fastening bolt 14 extends to the fixing socket 15, so that the end of the support plate 9 can be fixed on the supporting connecting rod 7, so that the multiple support plates 9 are more stable and safer after being unfolded, making it safer and more convenient for workers to pick up goods.
