Description

Technical Field

[0001] The utility model belongs to the technical field of cargo transportation, and in particular relates to a simple assembly trolley. Background Art

[0002] As a common logistics and transportation tool, trolleys are widely used in various fields, including warehousing, logistics, and supermarkets. They are primarily used to carry and transport various types of goods, reducing the burden of manual handling and improving transportation efficiency. Traditional trolleys typically consist of basic components: a base, wheels, and a handle. The base serves as a platform for loading goods, the wheels provide mobility, and the handle facilitates pushing the trolley. However, despite their important role in logistics and transportation, traditional trolleys still have many shortcomings in their structural design and user experience.

[0003] First, the assembly and disassembly process of traditional trolleys is relatively cumbersome. Because the various components are often connected by fasteners such as bolts, users often need tools such as wrenches during assembly and disassembly. This not only consumes a lot of time and energy, but also limits the trolley's rapid deployment and flexible use to a certain extent.

[0004] Secondly, the cargo platform of traditional trolleys is fixed in size and lacks flexibility. In practice, cargo often varies in size and weight, and a fixed-size platform may not be able to accommodate all cargo needs. This means users may need to switch to different trolleys when transporting cargo of varying sizes, increasing costs and inconvenience.

[0005] Therefore, it is very necessary to invent a simple assembly handcart. Utility Model Content
