Description

Technical Field

[0001] The present application relates to the technical field of tool boxes, and in particular to a roller tool box. Background Art

[0002] With the rapid development of modern industry and manufacturing, toolboxes, as important containers for storing and carrying various tools, are gaining increasing attention for their design and functions. Among the many types of toolboxes, roller toolboxes are particularly popular among workers and technicians because of their easy mobility and portability. The design of roller toolboxes is to provide a convenient, efficient and safe storage solution to meet the needs of carrying and using tools in different work scenarios.

[0003] Currently, most tool boxes on wheels on the market use a multi-layer stacking design. This design effectively saves space and allows the tool box to store more tools in a limited space. In order to ensure that the tools do not slip out of the box during transportation, most tool boxes on wheels use a top opening design. This design makes the tool box more stable when moving and reduces the risk of tools slipping due to bumps.

[0004] Although the multi-layer roller tool box with a top opening performs well in terms of stability and safety, this design also brings certain inconveniences. Especially when it is necessary to quickly access the tools located inside the lower box, the user has to remove the upper box first. This process is time-consuming and laborious, which reduces work efficiency. Summary of the invention
