Air Nozzle Joint Structure with Meshing Teeth for High-Pressure Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air filling methods, such as rotary engagement and thread rotation, fail to provide stable high-pressure air filling due to limitations in ease of operation and speed.
Innovation Solution
A joint structure for an air nozzle featuring a valve joint with a controlling assembly that allows the insertion and secure connection of the air nozzle using meshing teeth and a limiting member, enabling easy, smooth operation and high-pressure air filling by engaging or disengaging the air nozzle with the valve joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rotary engagement with compressed rubber is used, then quick engagement is achieved, but stable high-pressure air filling cannot be maintained
Solution Approach 1:
The limiting member is designed to be movable within the orifice, transitioning between limited and unlimited positions. When unlimited, it allows quick insertion; when limited, it secures the air nozzle for stable high-pressure operation. This dynamic positioning resolves the contradiction between quick engagement and stable high-pressure maintenance.
2Reliability
If thread rotation is used, then stable high-pressure air filling is achieved, but the operation is slow and manual
Solution Approach 1:
The invention extracts the threading function from the traditional screw mechanism and replaces it with a limiting member that engages with meshing teeth on the air nozzle. This extracted mechanism provides both quick operation and stable high-pressure performance without requiring manual thread rotation.
3Reliability
If a limiting member is added to control air nozzle insertion, then secure connection is achieved, but device complexity increases
Solution Approach 1:
The limiting member is integrated into the valve joint body structure, combining the functions of connection control and structural support in a single component. The meshing teeth on the air nozzle engage with this integrated limiting member, providing secure connection without adding separate complex mechanisms.

AI summary
A joint structure for an air nozzle contains a valve joint connected on an air nozzle to fill air, with the air nozzle including outer threads defined around an outer peripheral side thereof. The valve joint includes a body having a hole defined therein, an inlet communicating with the hole, and at least one orifice penetrating from an exterior environment to the hole. At least one limiting member is secured and moves in the at least one orifice and has meshing teeth formed on one end thereof to correspond to the hole. The meshing teeth engage with the outer threads of the air nozzle. The at least one limiting member has a defining segment arranged on another end thereof. A controlling assembly is fitted on the body and is used to control the at least one limiting member to move in the at least one orifice.
