Description

Technical Field

[0001] This utility model belongs to the field of flatbed cart technology, specifically relating to a foldable flatbed cart. Background Technology

[0002] To transport bulk goods, trolleys and other cargo-carrying tools are needed to improve the convenience and efficiency of goods transportation. Trolleys are designed to be lightweight and easy to carry, and due to their ease of use, they are widely used in warehouses, manufacturing plants, department stores, logistics centers, freight stations, or for short-distance handling during delivery.

[0003] An existing patent (publication number: CN207747914U) discloses a flatbed handcart, including: a flatbed, wheels, a pull rod, and a handle. The wheels are rotatably connected to the flatbed, and the handle is connected to one end of the pull rod and is vertically connected in a "T" shape. The other end of the pull rod is connected to a cone. A cavity is formed in the flatbed to accommodate the pull rod. The opening end of the cavity is located on one side of the flatbed, and a stop block for blocking the cone block is provided at the opening of the cavity. The stop block is connected to the flatbed and has a through hole. The inner diameter of the through hole is larger than the outer diameter of the pull rod and smaller than the outer diameter of the cone block.

[0004] An existing patent (publication number: CN 220639980 U) proposes a flatbed trolley handle mounting structure, which facilitates targeted replacement of damaged parts, reduces the scrap rate of equipment, facilitates maintenance work, improves the user experience, reduces the storage space required, and improves the convenience of the equipment.

[0005] In the aforementioned prior art, when used as a flatbed trolley, the goods are supported by a flatbed structure and placed directly on the flatbed. However, the flatbed has a limited load-bearing area and no obstructions around it. When the trolley is moved under force, the goods are prone to shifting or even falling off, causing damage. This has drawbacks.

[0006] In view of the above factors, this utility model provides a foldable flatbed cart, which is designed with a first set of movable guard plates and a second set of movable guard plates splicing form. The first set of movable guard plates and the second set of movable guard plates can be assembled to form a basket storage space or two basket storage spaces. When not in use, the second set of movable guard plates can be detached and placed in the forming groove by plugging in. Utility Model Content
