Protective plates are installed on the top of the movable platform and on both sides corresponding to the groove. An extension frame is rotatably connected to one side of each of the two protective plates and at one end of the movable platform. A plurality of second conveying rollers are rotatably connected between the two extension frames. A positioning hole is provided on the top of the protective plate. A positioning frame is installed on one side of each extension frame adjacent to the plurality of second conveying rollers. A sliding groove is provided inside the positioning frame. A positioning rod is slidably connected inside the sliding groove. A pin is fixedly connected to the bottom of the positioning rod, and one end of the pin is inserted into the positioning hole. A first spring is sleeved on the outside of the positioning rod and inside the sliding groove.

[0007] Preferably, a handle is installed between the two protective plates on the side away from the extension frame.

[0009] Preferably, the outer sides of the plurality of first conveying rollers and the plurality of second conveying rollers are all covered with rubber sleeves.

[0010] Preferably, a glow-in-the-dark sticker is installed on the outer side of the protective plate.

[0011] Preferably, the pedal has an L-shaped structure.

[0012] This utility model provides a cargo transport and delivery trolley, which has the following beneficial effects: 1. This cargo conveying and delivery trolley, through a rotating extension frame set at one end of the trolley, and with the action of multiple sets of first conveyor rollers inside the trolley and multiple sets of second conveyor rollers on the extension frame, can reduce the height difference between the cargo and the ground. The cargo can be manually assisted to enter or unload onto the trolley along the inclined angle of the extension frame, which helps to increase the stability of cargo unloading. In addition, the extension frame is easily fixed by sliding bolts in the positioning frame and plugs in the positioning holes on the protective plate, preventing the extension frame from rolling off during cargo movement.

[0013] 2. This cargo conveying and delivery trolley features sliding pedals installed on both sides of the platform. With the deformation of springs, the pedals can be pressed against the ground to stabilize the platform. This helps to prevent the platform from becoming unbalanced and tipping over when loading or unloading goods. It is convenient for single-person operation, and the pedals can automatically reset and distance themselves from the ground to prevent obstruction of the platform's movement.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a cargo conveying and delivery trolley, including a movable platform 1. The movable platform 1 has a groove 2 inside, and multiple first conveying rollers 3 are rotatably connected inside the groove 2. Protective plates 4 are installed on the top of the movable platform 1 and on opposite sides of the groove 2. An extension frame 5 is rotatably connected to one side of each of the two protective plates 4 and at one end of the movable platform 1. Multiple second conveying rollers 6 are rotatably connected between the two extension frames 5. By flipping and tilting the extension frames 5, one end of the extension frame 5 can touch the ground, reducing the height difference with the ground, and allowing the cargo to be conveyed more smoothly. The conveyor can roll along the first conveyor roller 3 and the second conveyor roller 6 for stable loading and unloading of goods. Rubber sleeves 18 are fitted on the outer sides of the multiple first conveyor rollers 3 and the multiple second conveyor rollers 6 to increase friction between the goods and the first or second conveyor rollers 3 or 6 and to prevent damage to their surfaces. A positioning hole 7 is provided at the top of the protective plate 4. A positioning frame 8 is installed on one side of the extension frame 5 adjacent to the multiple second conveyor rollers 6. A sliding groove 9 is provided inside the positioning frame 8, and a positioning rod 10 is slidably connected inside the sliding groove 9 for positioning. A bolt 11 is fixedly connected to the bottom of the rod 10. One end of the bolt 11 is inserted into the positioning hole 7. A first spring 12 is sleeved on the outside of the positioning rod 10 and inside the slide groove 9, so that the bolt 11 can be pulled out from the positioning hole 7 as the positioning rod 10 slides, releasing the fixing of the positioning frame 8 and the protective plate 4, or reset and inserted into the positioning hole 7 under the action of the first spring 12, fixing the positioning frame 8 and the protective plate 4, and controlling the retraction and extension of the extension frame 5. A convex sliding groove 14 is opened on both sides of the moving plate 1, and a convex sliding block is slidably connected inside the convex sliding groove 14. 15. A pedal 16 is fixedly connected to one side of the convex sliding block 15. The pedal 16 has an L-shaped structure. A second spring 17 is fixedly connected between the convex sliding block 15 and the convex sliding groove 14. Through the deformation of the second spring 17, the pedal 16 can be moved down and pressed against the ground to fix the position of the protective plate 4. This helps to prevent the moving platform 1 from becoming unbalanced and tipping over when loading or transporting goods. A luminous sticker 19 is installed on the outside of the protective plate 4 to remind the position of the moving platform 1 in low light. A handle 13 is installed on the side of the two protective plates 4 away from the extension frame 5.

[0018] In summary, when using this cargo transport and delivery trolley, pulling up the positioning rod 10 on one side of the positioning frame 8 of the extension frame 5 causes one end of its bottom bolt 11 to be pulled out from the positioning hole 7 on the protective plate 4, releasing the fixation between the protective plate 4 and the positioning frame 8. Then, the extension frame 5 can be rotated to tilt it, with one end touching the ground. As needed, the pedals 16 on both sides of the moving platform 1 can be stepped on. Through the connection between the pedals 16 and the convex sliding blocks 15 sliding in the convex sliding grooves 14 on both sides of the moving platform 1, and the deformation of the second spring 17 at the top of the convex sliding block 15, the pedals 16 and the convex sliding blocks 15 are connected, allowing the convex sliding blocks 15 to slide smoothly into the convex sliding grooves 14 on both sides of the moving platform 1. After the ground is aligned and the position of the moving platform 1 is fixed, the goods can be transferred to the multiple first conveyor rollers 3 inside the moving platform 1 by the rolling of multiple second conveyor rollers 6 on the inclined extension frame 5. Similarly, the goods on the multiple first conveyor rollers 3 can be pushed to the multiple second conveyor rollers 6 and then transferred to the ground. After the operation is completed, the pedal 16 is released, the second spring 17 drives the pedal 16 to automatically reset, and the extension frame 5 is flipped. The positioning rod 10 inside the positioning frame 8 is pulled, so that the plug 11 is inserted into the positioning hole 7 on the protective plate 4 again, and the positioning frame 8 and the extension frame 5 are fixed.
