Tool Box Locking Structure with Rotatable Handle for Visibility and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool boxes are inconvenient for users to access tools due to their flat design, which obstructs visibility, and lack antitheft protection, making displayed tools susceptible to theft.
Innovation Solution
A locking structure that includes a rotatable handle allowing the tool box to stand inclined, providing clear visibility and an antitheft mechanism where the cover is tightly locked to the box body, requiring destruction of locking ends to open, ensuring tools cannot be removed without permission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool box is designed in a flat-spread-out manner, then the structure is simple and easy to manufacture, but the user cannot see the whole inside of the tool box, making it inconvenient to find tools
Solution Approach 1:
The patent applies the dynamics principle by making the box body rotatable relative to the base through a pivot connection. This allows the box body to be rotated from a flat position to an inclined position, enabling users to view the interior contents clearly while maintaining a simple overall structure. The dynamic rotation mechanism resolves the contradiction between simplicity and visibility.
2Reliability
If the tool box is designed without locking mechanism, then the structure is simple, but the hand tools are likely to be stolen when being displayed
Solution Approach 1:
The patent merges the locking function with the existing structural components by having the cover's positioning hooks engage with positioning holes on the box body, and the handle's connecting portion engage with the engaging groove. This integration of locking functionality into existing structural elements provides antitheft protection without significantly increasing overall structural complexity.
Solution Approach 2:
The positioning hooks and positioning holes are pre-configured on the cover and box body respectively, creating a preliminary locking mechanism that prevents unauthorized opening before any theft attempt occurs. This preliminary anti-action ensures tools cannot be easily removed from the display.
3Reliability
If the cover is loosely attached to the box body, then the structure is simple and easy to open, but the cover cannot be tightly locked to prevent theft
Solution Approach 1:
The patent segments the opening operation into two distinct phases: normal operation where positioning hooks engage with positioning holes for secure locking, and authorized opening where the user applies sufficient force to disengage the hooks. This segmentation allows the cover to be both tightly locked during display and openable when needed.

AI summary
A locking structure for the box body is provided with a box body, a handle, and a cover. The handle is a rotatable structure which can support the box body to make the box body stand in an inclined manner, so as to allow the user to have a full clear view of the hand tools inside the tool box. On top of that, the tool box offers an antitheft feature, when the tool box is closed, the cover cannot be opened and removed from the box body unless the locking ends of the retainers are destroyed. Therefore, the hand tools cannot be taken out of the tool box without permission.
