Anti-Impact Rotating Tongue Lock with Falling Block Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices and locks are vulnerable to impact damage, which compromises their safety and security, especially in applications like bank safes and firearm cabinets where mechanical strength is crucial.
Innovation Solution
An anti-impact rotating tongue type storage device and lock system that incorporates a lock body with a rotating tongue, a blocking assembly, an actuating assembly, and a falling block assembly. The falling block assembly supplements the blocking function of the actuating assembly when the lock shell is subjected to an impact force, enhancing the device's resistance to damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lock or other portions of the storage device are subjected to an impact force, then the impact force converted from an impact momentum easily leads to damage to the storage device or falling of the lock, but the mechanical strength and safety of the storage device need to be improved
Solution Approach 1:
The patent introduces a falling block assembly that acts as a pre-positioned protective mechanism. When impact force is detected, the falling block automatically moves to block the rotating tongue, preventing impact damage before it can propagate through the locking mechanism. This beforehand cushioning approach addresses the contradiction by preparing a protective measure in advance that activates only when needed.
Solution Approach 2:
The falling block assembly serves as an intermediary element between the impact force and the locking mechanism. It intercepts the impact force and converts it into a blocking action, mediating the harmful effect and protecting the critical locking components from direct impact damage.
2Reliability
If a blocking assembly is used to control the rotating tongue, then the locking function is improved, but the device complexity increases due to the need for actuating and falling block assemblies
Solution Approach 1:
The falling block assembly is designed to activate automatically through self-service mechanisms. The impact force itself triggers the falling block to move into the blocking position, eliminating the need for external control systems or additional actuators. This self-service approach improves reliability while minimizing the increase in device complexity.
Solution Approach 2:
The patent combines the blocking function with the existing rotating tongue mechanism by integrating the falling block assembly into the same structural space. The falling block works in conjunction with the rotating tongue rather than as a completely separate system, merging functions to reduce overall complexity while maintaining improved reliability.

AI summary
Provided is an anti-impact rotating tongue type storage device. The storage device includes: a box body; a locking mechanism arranged in the box body; and a lock body that selectively cooperates with or separates from the locking mechanism, the lock body includes: a lock shell that remains stationary relative to the locking mechanism in working state; a rotating tongue that selectively cooperates with or separates from the locking mechanism and rotates relative to the lock shell; a blocking assembly that selectively blocks or avoids the rotating tongue within rotation travel of the rotating tongue; an actuating assembly that selectively blocks avoidance of the blocking assembly at first position within avoidance travel of the blocking assembly; and a falling block assembly arranged at second position within the avoidance travel of the blocking assembly, that supplements blocking function of the actuating assembly when the lock shell is subjected to impact force.
