Sealing Cover With Integrated Operating Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing covers for barrel bodies have complex assembly processes due to a large number of assembly elements, resulting in high production costs.
Innovation Solution
A sealing cover design featuring an outer cover body, an inner cover body with a platform and airtight ring, and an operating member with pivotally connected mounting parts and sliding posts that drive the inner cover body between sealed and unsealed positions, reducing the number of assembly elements and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional transmission unit with multiple assembly elements (driven member, shift lever, pivot pin, resilient element) is used, then the sealing function can be achieved, but the assembly complexity increases and production cost rises
Solution Approach 1:
The patent merges the driven member, shift lever, and pivot pin into a single integrated operating member. This operating member includes a pressing portion that directly contacts the airtight ring and a lever portion that pivots about a pivot axis, eliminating the need for separate assembly elements while maintaining the sealing function.
Solution Approach 2:
The operating member serves multiple functions: it acts as both the driven member that presses the airtight ring and the shift lever that translates rotational motion into linear motion. The pivot connecting portion integrates the pivot pin function into the outer cover body structure, reducing the total number of components.
2Reliability
If a conventional transmission unit with multiple assembly elements is used, then the sealing mechanism can be implemented, but the production cost increases due to complicated assembly steps
Solution Approach 1:
By combining multiple components into the operating member and integrating the pivot pin function into the outer cover body's pivot connecting portion, the number of assembly steps is reduced. The simplified structure requires fewer assembly operations and reduces production complexity.
3Reliability
If the airtight ring is continuously pressed against the barrel body, then effective sealing is maintained, but the airtight ring cannot restore its shape and the sealing cover cannot be opened
Solution Approach 1:
The operating member pivots between a first position (sealing) and a second position (unsealing). When pivoted to the first position, the pressing portion applies force to deform the airtight ring for sealing. When pivoted to the second position, the pressing force is released, allowing the airtight ring to restore its original shape through elastic recovery, enabling the sealing cover to be opened.
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 reduces assembly complexity and production costs while ensuring effective sealing and easy operation, with the airtight ring being airtightly pressed between the barrel and outer cover body in the sealed position and restoring to its original shape in the unsealed position.
Implementation Method 1
the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body
Implementation Method 2
the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body
Implementation Method 3
the sliding posts slide respectively in the rail holes to drive movement of the inner cover body relative to the outer cover body

AI summary
A sealing cover for covering an opening of a barrel body includes an outer cover body, an inner cover body, an airtight ring and an operating member. The outer cover body includes two pivot connecting portions. The airtight ring is sleeved on an outer peripheral surface of the inner cover body. The operating member is pivotally connected to the pivot connecting portions and the inner cover body. The operating member is operable to pivot so as to drive movement of the inner cover body between a sealed position and an unsealed position. When at the sealed position, the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body. When at the unsealed position, the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body.
