Linear Actuator Toggle Restraining Mechanism for Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-releasing mechanisms in linear actuators require external force to maintain the interrupted transmission state, causing inconvenience in use.
Innovation Solution
A linear actuator with a restrainable quick-releasing mechanism, incorporating a toggle restraining mechanism that includes a stem, rotating element, and restraining assembly, allows the mechanism to be restrained without external force, using a rotating arm to disengage the sliding sleeve from the clutch and an engaging element to lock the rotating element, maintaining the quick release status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pulling rod or rope is used to drive the rotating element to engage and disengage the clutch, then the quick release effect can be accomplished, but external force must be continuously applied to maintain the interrupted transmission state
Solution Approach 1:
The rotating element is designed with an engaging element that automatically engages with a restraining hole when the rotating element rotates to a specific angle, allowing the mechanism to maintain the interrupted transmission state without continuous external force. The system serves itself by using the rotation motion to trigger the restraining assembly activation.
Solution Approach 2:
The restraining assembly acts as an intermediary between the rotating element and the sliding sleeve. When the engaging element engages with the restraining hole, it mediates the transmission of force to push the sliding sleeve and separate it from the second clutch, maintaining the quick release state without requiring continuous external force on the pulling rod.
2Ease of operation
If the sliding sleeve is pushed by a rotating arm to separate from the second clutch, then the transmission interruption is achieved, but the mechanism requires external force to initiate the rotation
Solution Approach 1:
The engaging element is pre-positioned and elastically pushed by the restraining spring, ready to engage with the restraining hole. When the rotating element rotates to the specific angle, the engaging element automatically engages with the restraining hole, initiating the pushing action on the sliding sleeve without requiring additional external force.
Solution Approach 2:
The restraining spring provides dynamic elastic force to push the engaging element. When the rotating element reaches the specific angle, the spring's elastic force is converted into the pushing force on the sliding sleeve, allowing the system to transition from a static force requirement to a dynamic self-actuating mechanism.
