Tap Handle Mounting Structure with Limiting Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tap handle mounting structures suffer from irregular openings and seams, which affect the integrity and cleanliness of the product, and are difficult to disassemble and assemble due to interference fits.
Innovation Solution
A mounting structure featuring a ball-head connection part that rotates within a body, utilizing a first and second limiting sleeve for a rotary clamping connection, allowing for easy assembly and disassembly, and reducing the rotation stroke of the handle, thereby improving the product's integrity and aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a plastic piece with interference fit is used to fix the ball head structure in the body, then the integrity of the product is improved by hiding the rotation part, but the disassembly and assembly process becomes difficult and the plastic piece is liable to damage
Solution Approach 1:
The mounting structure is divided into separate components: a limiting sleeve that can be detached from the body, and a ball head connection part that can be detached from the handle. This segmentation allows for easy disassembly and assembly while maintaining the integrated appearance when assembled, resolving the contradiction between product integrity and ease of operation.
Solution Approach 2:
The limiting sleeve acts as an intermediary component between the ball head connection part and the body. It provides a secure mounting interface that allows the ball head structure to be hidden within the body for aesthetic purposes, while also enabling easy detachment when needed, thus resolving the contradiction between maintaining integrity and facilitating disassembly.
2Ease of operation
If the handle is fixedly connected to the valve rod, then the valve core operation is achieved, but irregular openings and seams appear at the connection position affecting product integrity
Solution Approach 1:
The ball head connection part is nested within the body of the tap, with the limiting sleeve providing a secure fit. This nesting arrangement hides the connection part within the body, eliminating irregular openings and seams that would otherwise be visible, thus maintaining product integrity while preserving the operational functionality of the valve core.
Solution Approach 2:
The limiting sleeve is designed with specific local properties including a clamping groove that provides secure retention of the ball head connection part, and a rotation stopping protrusion that prevents excessive rotation. These localized structural features ensure both the operational integrity and aesthetic appearance of the connection area.
3Ease of operation
If the ball head connection part is rotated to toggle the valve core, then the opening and closing function is achieved, but dirt accumulates at the seams and the appearance is affected
Solution Approach 1:
By nesting the ball head connection part within the body and using the limiting sleeve to secure it, the design eliminates gaps and seams where dirt could accumulate. The smooth, integrated appearance prevents dirt buildup while maintaining the rotational motion necessary for the opening and closing function.
Solution Approach 2:
The limiting sleeve is designed with a smooth outer surface and specific local features like the clamping groove and rotation stopping protrusion that prevent dirt accumulation. These localized structural improvements ensure that the visible portions of the tap maintain a clean, aesthetic appearance while preserving operational functionality.

AI summary
A mounting structure of a tap handle and a shower tap, wherein the handle(3) includes a ball-head connection part(31) rotating around a first axis vertical to an axis of a body to toggle the valve core(2) to open and close; a first limiting sleeve(4) is clamped to the inner wall of the body(1) by coaxial relative rotation, and an inner wall surface thereof is provided with an arc surface matched with the ball-head connection part(31); a second limiting sleeve(5) is coaxially arranged at an end portion of a first end of the body(1) and clamps the ball-head connection part(31) between the second limiting sleeve(5) and the first limiting sleeve(4),and is detachably and fixedly connected to an inner wall of the body(1) and establishes a rotation stopping connection relationship with the first limiting sleeve(4). The handle(3) is arranged on an end portion of the body(1) by the mounting structure of the handle tap.
