Description

Technical Field

[0001] The utility model relates to the technical field of handcart wheels, in particular to a quickly detachable handcart wheel. Background Art

[0002] As a commonly used transportation tool, the handcart is widely used in industrial, commercial and household environments. The design of traditional handcart wheels is mainly fixed installation. Although this design is simple and reliable, there are some deficiencies in actual use. Traditional handcart wheels usually require tools and a relatively long time to complete installation and disassembly. Especially when the wheels need to be replaced or maintained, this cumbersome process will reduce work efficiency and increase operation complexity.

[0003] In order to improve the convenience of using handcart wheels, various improved disassembly technologies have emerged on the market. For example, some handcarts adopt a quick-release design. By using quickly released bolts or clamps, users can quickly disassemble the wheels without tools. Although these designs can improve the disassembly efficiency to a certain extent, there are still some problems, such as insufficient firm fixation and easy loosening during the disassembly process.

[0004] With the increasing frequency of using handcarts in industrial production and daily life, the requirements for disassembly and maintenance of handcart wheels are also increasing day by day. Especially in some scenarios where the wheels need to be frequently replaced, such as logistics centers, manufacturing plants and some household applications, the traditional handcart wheel design is particularly inconvenient.
