Hydraulic Jack Safety Pin Lock Against Sudden Piston Collapse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hydraulic jacks lack sufficient safety measures, leading to risks of sudden piston collapse or load slipping, even when used with jack stands, due to unreliable anti-slip mechanisms and bulkiness when integrated with jack stands.
Innovation Solution
A hydraulic jack design featuring a piston with drill holes and a security piece that includes through holes and a safety pin to secure the piston in place, providing additional safety against sudden collapse and improved portability by separating the safety components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a jack stand is used with the hydraulic jack, then safety against sudden piston collapse is improved, but the device becomes bulky and inconvenient to carry
Solution Approach 1:
The patent integrates the safety function directly into the hydraulic jack by incorporating a safety pin that passes through the piston and a retention mechanism on the jack body, merging the safety function with the jack itself rather than requiring a separate jack stand
Solution Approach 2:
The hydraulic jack is designed to perform multiple functions: lifting loads and providing safety against collapse, by integrating both the lifting mechanism and the safety retention system into a single device
2Reliability
If a jack stand is welded to the hydraulic jack, then safety is improved, but the device becomes bulky and inconvenient to carry
Solution Approach 1:
The safety retention mechanism is integrated into the jack's existing structure rather than being added as a separate welded component, maintaining safety functionality while avoiding increased bulkiness
3Device complexity
If traditional hydraulic jack design is used, then simplicity is maintained, but safety against sudden piston collapse is insufficient
Solution Approach 1:
The safety pin is pre-positioned and the retention mechanism is pre-installed on the jack, so that safety protection is automatically provided when the piston is raised, without requiring additional actions from the user
Solution Approach 2:
The safety pin acts as an intermediary element between the piston and the retention mechanism, providing a simple mechanical connection that ensures safety without complicating the overall design

Function Achieved in This Case
Enhances user safety by preventing unexpected piston movement and improves convenience through a more compact and modular safety system that can be easily attached to the hydraulic jack.
Implementation Method 1
a piston (31) installed in the hydraulic cylinder (30) that is raised up from the hydraulic cylinder (30) by pressure of the hydraulic fluid stored in the hydraulic cylinder (30)
Data Source
AI summary
A hydraulic jack for providing safety and security is disclosed. The hydraulic jack comprises a hydraulic cylinder storing hydraulic fluid inside, and a piston installed in the hydraulic cylinder that is raised up from the hydraulic cylinder by pressure of the hydraulic fluid stored in the hydraulic cylinder, thereby a heavyweight can be lifted by the piston. The piston has at least one drill hole on its body thereof that has a determined diameter and is perpendicular to the piston. A security piece is attachable on a top portion of the hydraulic cylinder. The security piece comprises a pair of through holes, which align with at least one drill hole of the piston.
