Clamping Structure for Mounting Reducer with Hinge and Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping structures for fire sprinkler reducers face challenges with inconvenient separation and disassembly, difficulty in coupling, and distortion under strong torque, particularly due to the one-sided open securing groove design which makes them unsuitable for high-torque applications.
Innovation Solution
A clamping structure featuring a clamp body and clamp door that can be easily rotated about a hinge pin, utilizing a latch member and lever mechanism to securely couple and decouple, with various fastening and latch configurations to prevent separation or distortion even under high torque, such as 900 Kg/m2 or more.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-sided open securing groove design is used for the clamp door, then the structure is simple and easy to manufacture, but the clamp body and clamp door come apart or distort under strong torque of 900 Kg/m2 or more
Solution Approach 1:
The securing groove is divided into a first securing groove (open at one side) and a second securing groove (open at the other side), with the latch member engaging both grooves. This segmentation distributes the torque load across multiple engagement points, preventing the clamp body and clamp door from coming apart or distorting under high torque conditions while maintaining manufacturing simplicity.
2Device complexity
If the clamp door is rotated about the rotation coupling point of the hinge pin to be opened, then the coupling structure is simple, but coupling is difficult and disassembly operation is inconvenient due to the need to rotate the nut
Solution Approach 1:
A lever member is introduced as an intermediary tool to operate the latch member. The lever member engages with the latch member and provides mechanical leverage, allowing the clamp door to be coupled or disconnected with simple lever motion rather than requiring nut rotation. This maintains simple device structure while dramatically improving ease of operation.
3Device complexity
If a typical flexible joint connection is used between sprinkler and reducer, then the connection is simple, but separation or disassembly is inconvenient
Solution Approach 1:
The clamp door is designed to be dynamically movable relative to the clamp body through the hinge pin rotation mechanism. When the latch member is disengaged, the clamp door can be easily rotated open to allow quick separation and disassembly of the sprinkler reducer connection, while maintaining a simple overall device structure. This dynamic design enables easy maintenance and repair operations.
