Folding Lock Anti-Push-Open Mechanism Using Embedding Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding locks are vulnerable to thieves pushing open the insertion groove of the lock seat, allowing the lock column to be detached from the folding plate, resulting in inadequate anti-theft efficacy.
Innovation Solution
A folding lock design featuring a folding plate assembly with a connecting seat, a fixing sleeve, a lock core seat, and a lock column, which includes a torsion spring and anti-drilling components to securely embed and fasten the lock column, preventing push-opening and providing anti-drilling protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the insertion groove of the lock seat is provided for the lock column to insert into the folding plate, then the locking action is completed, but the insertion groove can be easily push-opened by thieves using a tool to detach the lock column
Solution Approach 1:
The patent applies preliminary anti-action by providing an embedding groove and embedding portion structure before the locking action occurs. The embedding groove is pre-formed in the lock seat, and the embedding portion is pre-formed on the lock column, creating a pre-established anti-push-open mechanism that prevents thieves from easily detaching the lock column through push-opening attacks.
Solution Approach 2:
The patent segments the insertion structure into two distinct parts: the insertion groove in the lock seat and the embedding groove/embedding portion structure on the lock column. This segmentation creates a multi-stage locking mechanism where the lock column first inserts into the insertion groove and then embeds into the embedding groove, making it more difficult for thieves to detach compared to a single insertion structure.
2Reliability
If the lock column is securely embedded and fastened to prevent push-opening, then the anti-theft efficacy is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the lock column structure. The lock column integrates the insertion portion for initial insertion, the embedding portion for secure fastening, and the positioning protrusion for precise alignment. By combining these functions into a single component rather than using separate parts, the patent enhances anti-theft efficacy while controlling device complexity.
Solution Approach 2:
The patent applies self-service through the elastic deformation mechanism of the lock column. The lock column automatically deforms elastically during insertion to engage with the embedding groove, and the positioning protrusion automatically aligns with the positioning hole without requiring additional fastening operations. This self-service mechanism secures the lock column while avoiding complex fastening structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents thieves from opening the lock by embedding and fastening the lock column, enhancing the anti-theft efficacy and protecting against drilling attacks.
Implementation Method 1
a torsion spring, one end of the torsion spring being embedded in the fixing insert hole of the connecting swivel, another end of the torsion spring being embedded in the fixing insert hole of the lock core seat
Implementation Method 2
a positioning steel ball, another end face of the lock core seat being provided with a fixing insert hole, the positioning steel ball being embedded in the arcuate positioning embedding groove of the fixing sleeve
