Electrical Device Mounting Structure With Sliding Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting structures for electrical devices are prone to unlocking under external forces, leading to potential detachment from mounting surfaces during direct mounting, especially when using screw holes in sliding parts.
Innovation Solution
The mounting structure incorporates sliding parts with guide rails and engagement mechanisms that lock into projecting position locking parts on the mounting main body, ensuring secure fixation by direct contact with the mounting surface, even under external forces, through the use of sliding engagement parts and guide parts that differ in direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sliding part is locked by the locking piece engaging the locking hole in the conventional manner, then the sliding part can be fixed to the mounting main body, but the locking piece may come out of the locking hole when a large external force acts on the electrical device, causing the sliding part to unlock
Solution Approach 1:
The invention transitions from a single-point locking mechanism (locking piece engaging locking hole) to a distributed contact mechanism where the sliding engagement part maintains contact with both the projecting position locking part and the mounting surface along a linear dimension, distributing the external force across multiple contact points and preventing unlocking
Solution Approach 2:
The sliding engagement part is preliminarily configured to engage the projecting position locking part and contact the mounting surface before external forces are applied, establishing a pre-loaded mechanical connection that resists subsequent external forces acting on the electrical device
2Adaptability or versatility
If the sliding part is provided with screw holes for direct mounting, then the electrical device can be mounted on a mounting surface, but the electrical device could be detached along with the mounting main body if the sliding parts are unlocked
Solution Approach 1:
The invention adds a spatial dimension to the locking mechanism by extending the sliding engagement part to contact both the projecting position locking part and the mounting surface simultaneously, creating a triangular stabilization effect that prevents detachment in multiple directions
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
This configuration securely fixes the sliding parts to the mounting main body during direct mounting, preventing movement and ensuring stability even if the sliding parts are unlocked, by maintaining contact with the projecting position locking parts and the mounting surface.
Implementation Method 1
both sides of the sliding engagement part in a direction perpendicular to the bottom surface are in direct contact with the projecting position locking part and the mounting surface
Implementation Method 2
a guide part provided on the bottom surface... movable in a sliding direction along a bottom surface of the mounting main body by a guide part

AI summary
A mounting structure (1) for an electrical device includes a mounting main body (2) that houses an electrical device, and a sliding part (3) that is movable in a sliding direction along a bottom surface (21) of the mounting main body (2) by a guide part provided on the bottom surface (21). The sliding part (3) includes a through hole (39) for insertion of a mounting screw, and a sliding engagement part (34) that engages a projecting position locking part (254) formed in a recessed shape on the bottom surface (21) when the sliding part (3) is disposed at a projecting position at which the through hole (39) is located outwardly of a side surface of the mounting main body (2). In a state in which the sliding part (3) is disposed at the projecting position and the mounting main body (2) is directly mounted on a mounting surface, both sides of the sliding engagement part (34) in a direction perpendicular to the bottom surface (21) are in contact with the projecting position locking part (254) and the mounting surface. This allows the sliding part (3) to be securely fixed to the mounting main body (2).
