Hose Joint Locking Structure for Sealing Under Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hose joints fail to effectively seal hoses and prevent screw cap counterrotation due to vibration, leading to sealing issues and safety concerns during high-speed operations.
Innovation Solution
A sealing vibrational-counterrotation-proof hose joint design featuring a connecting section with hooking claws, a squeezing section, locking blocks, spiral guide bars, and a sealing ring, which securely locks the screw cap to the main body and prevents counterrotation through rotational interaction and anti-falling ring mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a buckle-type quick-inserting structure is used for rapid assembly and disassembly, then assembly speed is improved, but sealing effectiveness deteriorates due to large gaps between components
Solution Approach 1:
The hose joint is divided into multiple functional segments: a connecting section with hooking claws for rapid attachment, a squeezing section for sealing, and locking blocks with spiral guide bars for anti-counterrotation. Each segment performs a specific function, allowing quick assembly while maintaining sealing effectiveness through the coordinated action of these segmented components.
2Strength
If a knob-type threaded connection is used for tight connection, then connection strength is improved, but counterrotation resistance deteriorates during high-speed operation due to vibration
Solution Approach 1:
The locking mechanism uses dynamic elements including locking blocks that move along spiral guide grooves formed by spiral guide bars. As the screw cap is tightened, the locking blocks are guided along the spiral path and eventually engage with locking grooves, creating a dynamic locking action that prevents counterrotation during high-speed operation while maintaining strong connection.
3Reliability
If a sealing ring deformation mechanism is used for hose fixation, then hose fixing is improved, but pulling resistance deteriorates
Solution Approach 1:
The invention merges multiple fixation mechanisms into one integrated system: the squeezing section deforms the sealing ring to wrap and fix the hose, while simultaneously the hooking claws engage with grooves in the hose and the locking blocks engage with locking grooves in the connecting section. This combination of mechanisms provides both secure hose fixing and high pulling resistance.
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 achieves ideal sealing and fixing effects while preventing screw cap counterrotation, ensuring stability and safety by securely clamping the hose and resisting vibration-induced rotation.
Implementation Method 1
a plurality of spiral guide bars; the spiral guide bars are uniformly distributed in a circumferential direction by taking the central axis of the joint main body as the center; a spiral guide groove for guiding the locking block is formed between every two adjacent spiral guide bars
Implementation Method 2
the locking grooves are respectively formed at the tail end of the spiral guide groove, allowing the locking blocks to be clamped and locked therein
Implementation Method 3
the squeezing section can squeeze the hooking claws, thereby enabling the hooking claws to bend towards the central axis of the joint main body
