Linear Sliding Rail Pre-Pressure Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear sliding rails experience vibrations, noises, and wear due to minor defects and action forces on the connecting bodies, leading to errors in high-precision applications.
Innovation Solution
An engaging device for a linear sliding rail that generates pre-pressure on the sliding block through a locking mechanism with positioning plates, abutting pieces, protruding plates, and locking pieces, ensuring a tight and firm assembly of the supporting body and connecting bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the sliding block structure is used with connecting bodies on front and rear ends, then the linear sliding rail can perform linear displacement, but the action force generates vibrations, noises and wear through minor gaps between constituent elements
Solution Approach 1:
The locking piece is designed to pre-tighten the connecting bodies to the sliding base body before operation begins. This preliminary action eliminates gaps between constituent elements, preventing vibrations, noises and wear that would otherwise occur during linear displacement operations.
Solution Approach 2:
The locking mechanism changes the structural parameter of the assembly by applying pre-pressure, transforming the loose fit state into a tight fit state. This parameter change (from loose to tight connection) eliminates the harmful effects of gaps while maintaining the linear displacement function.
2Ease of manufacture
If conventional linear sliding rail structure is used, then assembly is simple, but the connecting bodies are subjected to pressure and tension force causing minor defects
Solution Approach 1:
The locking piece applies pre-pressure to the connecting bodies before they are subjected to operational loads. This preliminary tightening action ensures that the connecting bodies are securely fastened, preventing pressure and tension forces from causing minor defects or failures during operation.
3Ease of operation
If the sliding block components are loosely assembled, then assembly is easier, but the action force causes vibrations and noises through minor gaps
Solution Approach 1:
The locking mechanism performs a preliminary tightening action that secures all sliding block components together before operation. This pre-assembly tightening eliminates gaps between components, preventing vibrations and noises from being generated during use, while still maintaining relatively simple assembly procedures.

AI summary
An engaging device of a linear sliding rail includes a sliding rail and a sliding block. The sliding block comprises a sliding base body, a supporting body and two connecting bodies. The front and rear ends of the sliding base body have a positioning plate respectively. The two locking pieces each comprises hooks. The hook locks the two connecting bodies at the front and rear ends of the sliding base body. The hook abuts against one end of the abutting piece. The other end of the abutting piece abuts against front and rear end faces of the supporting body respectively. Via this arrangement, when the locking piece locks the two connecting bodies at both ends of the sliding base body, it also generating a pre-pressure to press the supporting body, thereby assembling the supporting body and the two connecting bodies on the sliding base body tightly and firmly.
