Ceiling Fan Down Rod Locking Structure for Quick Stable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fan fixing structures using screws are cumbersome and time-consuming for installation and disassembly, and rotary screwing connections can lead to instability and safety concerns due to loosening over time.
Innovation Solution
A down rod installation structure featuring a coupling seat with an internal thread and an elastic member that includes an elastic portion and an abutment portion, allowing for quick and secure attachment of the down rod to the coupling seat through a threaded connection and elastic displacement for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or rotary screwing connection are used to fix the ceiling fan, then the assembly is secure, but the installation and disassembly process becomes complicated and time-consuming
Solution Approach 1:
The fastening system is segmented into a coupling portion with internal thread and a down rod with external thread, allowing for modular assembly. The elastic member is separated into an elastic portion and an abutment portion, enabling independent function of each component in the fastening process
Solution Approach 2:
The elastic member is extracted as a separate component from the traditional screw fastening system. This elastic member with abutment portion can be easily inserted and removed through the perforation, providing a quick release mechanism that eliminates the need for complex screw operations
2Stability of the object's composition
If screws are used to assemble the ceiling fan components, then the connection is stable, but the disassembly and reassembly process becomes inconvenient
Solution Approach 1:
The elastic member automatically engages with the down rod when assembled, with the abutment portion fitting into the aperture to create a self-locking effect. During disassembly, the elastic member can be easily removed through the perforation, allowing the down rod to be quickly detached without complex tools or procedures
Solution Approach 2:
The elastic member acts as an intermediary between the coupling portion and the down rod, providing both the locking function and the release mechanism. The abutment portion of the elastic member mediates the connection by engaging with the aperture in the down rod, enabling both secure attachment and easy removal
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
Facilitates quick and stable installation of the ceiling fan, reducing assembly complexity and ensuring the down rod remains securely attached, thereby enhancing safety and reducing the risk of loosening during operation.
Implementation Method 1
the elastic portion has a fixed end and a free end connected to the fixed end. The fixed end of the elastic portion is fixed to the coupling seat. The abutment portion is connected to the free end of the elastic portion. When the abutment portion is pushed by the down rod to elastically displace the abutment portion and the free end of the elastic portion to be in a stressed state

AI summary
A down rod installation structure for a ceiling fan has a coupling seat, a down rod, and an elastic member. The down rod is threadedly connected to the coupling seat. The elastic member has a fixed end that is fixed to the coupling seat. The elastic member further has an abutment portion to be engaged in a perforation of the coupling seat and an aperture of the down rod, so that the down rod installation structure invention has the advantages of quick installation and increasing the stability of the ceiling fan.
