Telescopic Rod Connector With Self-Mounting Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telescopic rods require mounting components for installation between door frames or walls, which is inconvenient and limits flexibility in use.
Innovation Solution
A telescopic rod connector comprising a screw rod, an inner sleeve, and an outer sleeve, where the inner sleeve can rotate and slide along the rod body, driven by the outer sleeve's rotation, allowing the telescopic rod assembly to adjust length and be mounted between door frames or walls without additional mounting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting components (fixing block, supporting frame) are used to install telescopic rod, then the telescopic rod can be securely mounted between door frames or walls, but the installation process becomes complex and requires additional components
Solution Approach 1:
The patent merges the mounting function directly into the telescopic rod structure by integrating a fixing block with limiting slots and limiting rods that interact with the door frame, eliminating the need for separate mounting components. The telescopic rod body itself becomes the mounting structure through the integrated fixing block design.
Solution Approach 2:
The telescopic rod assembly is designed to perform multiple functions: it serves as both the structural mounting element and the functional telescopic component. The fixing block with limiting slots and rods provides both positioning and securing functions, while the telescopic mechanism provides both adjustment and mounting capabilities.
2Reliability
If mounting components are used for installation, then the telescopic rod can be firmly fixed, but the convenience of installation is reduced
Solution Approach 1:
The telescopic rod assembly is designed to be self-mounting through its integrated fixing block that automatically engages with the door frame. The limiting slots and limiting rods work together to provide automatic positioning and securing without requiring separate mounting operations or additional components.
3Ease of operation
If the telescopic rod structure is simplified to eliminate mounting components, then installation becomes more convenient, but the ability to securely mount between door frames or walls is compromised
Solution Approach 1:
The fixing block is segmented into functional elements including limiting slots and limiting rods that work together to provide secure mounting. The telescopic rod is divided into inner and outer rods with independent movement capabilities, allowing the fixing mechanism to remain simple while maintaining security.

Function Achieved in This Case
Enables convenient assembly and disassembly of telescopic rod assemblies between door frames or walls, with flexible length adjustment, eliminating the need for mounting components and simplifying installation processes.
Implementation Method 1
A first helix and a first lifting groove are wound around the rod body. The inner sleeve includes at least two arc members and at least one connecting piece... the first helix is matched with the second lifting groove, and the second helix is matched with the first lifting groove so that the inner sleeve can rotate and slide around the rod body
Implementation Method 2
when the inner sleeve is sliding from the first end to the second end, the outer arc members are squeezed and opened

AI summary
The present invention discloses a telescopic rod connector, which includes an outer sleeve, an inner sleeve and a screw rod. The screw rod has opposite a first end and a second end, and a rod body between them. The inner sleeve sleeves on the rod body and can rotate and slide along it, and the inner sleeve is provided with positioning convex strips. The outer sleeve includes a notch ring and a plurality of outer arc members extending from the notch ring. U-shaped notches are arranged between adjacent two the outer arc members; the outer sleeve is arranged on the outside of the inner sleeve and the notch ring is close to the first end, and the positioning convex strips are inserted into the U-shaped notches. The outer sleeve is rotated to drive the inner sleeve to slide along the rod body.
