Quick-Disassembly Nipple Connector with Dynamic Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nipple connector structures face issues with poor pressure bearing capacity, frequent breakage of gripping jaws, and inefficient operation due to excessive clamping force, leading to difficulties in separation and alignment with grease nipples, especially in confined spaces, resulting in low work efficiency and reduced service life.
Innovation Solution
A quick-disassembly nipple connector structure featuring a handle that allows for upward or downward pulling to achieve accurate alignment, comprising a pivoting assembly, screwing member, gripping jaws, sleeve, and handle, which can move between lock and release positions to securely engage or disengage from the grease nipple, improving alignment and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the gripping jaws exert excessive clamping force to ensure secure connection under high pressure, then the pressure bearing capacity is improved, but the gripping jaws become prone to breakage and damage, reducing service life
Solution Approach 1:
The patent introduces a spring mechanism that allows the gripping jaws to dynamically adjust their clamping force. The spring provides continuous elastic pressure to maintain secure connection while absorbing shock and preventing excessive force that would damage the gripping jaws, thus resolving the contradiction between pressure bearing capacity and service life
Solution Approach 2:
The patent changes the physical state of the gripping system by introducing elastic deformation through the spring mechanism. This allows the system to maintain high clamping force through elastic recovery rather than rigid mechanical force, reducing stress concentration and preventing breakage while maintaining pressure bearing capacity
2Ease of operation
If the user shakes the nipple connector structure manually to separate it from the grease nipple, then the connection can be broken, but the operation is complex and time-consuming, reducing work efficiency
Solution Approach 1:
The patent extracts the separation function from manual shaking operations and implements it through a dedicated releasing component. This component actively pushes the gripping jaws to release the grease nipple, transforming a complex manual operation into a simple one-handed action and significantly improving work efficiency
Solution Approach 2:
The patent introduces a releasing component as an intermediary mechanism between the user's hand and the gripping jaws. This mediator translates simple user input into the complex motion required to release multiple gripping jaws simultaneously, simplifying the operation while maintaining control
3Ease of operation
If the nipple connector structure is manually aligned with the grease nipple through shaking, then connection can be achieved, but the alignment accuracy is poor and time-consuming, especially in confined spaces
Solution Approach 1:
The patent incorporates a guiding structure that performs preliminary alignment of the nipple connector with the grease nipple before the actual connection occurs. This pre-alignment mechanism ensures accurate positioning automatically, eliminating the need for manual shaking and significantly improving both alignment accuracy and operation speed in confined spaces

AI summary
Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve and a handle. The handle can be pulled by users to enable the quick-disassembly nipple connector structure to be rapidly connected to or separated from a grease nipple. When the handle is pulled downwards, the sleeve is located at a lock position to lock the grease nipple; and when the handle is pulled upwards, the sleeve is located at a release position to release the grease nipple. Thus, the quick-disassembly nipple connector structure has the advantages of being capable of improving work efficiency, high in positioning speed, high in accuracy and good in fixing property and has a good overall constituent strength, so that the motion stability is improved, and the operation smoothness and service life are ensured.
