Laser Module Lift Rail Locking Block for Smooth Precision Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser module lifting apparatuses experience unsmooth sliding and reduced positioning precision due to direct locking screw jacking, which shortens the service life of the lifting slide rail.
Innovation Solution
A locking block is arranged at the locking end of the locking screw, converting point contact to surface contact type locking, with a locking block made from stainless steel and an 'L'-shaped design, ensuring plane contact with the lifting slide rail, thereby improving the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking screw directly jacks the lifting slide rail, then the locking function is achieved, but the sliding smoothness deteriorates and positioning precision is reduced
Solution Approach 1:
The locking block serves as an intermediary component between the locking screw and the lifting slide rail. The locking screw pushes the locking block, which then contacts the lifting slide rail to achieve locking. This mediator prevents direct contact between the locking screw and the slide rail, eliminating the depression problem and maintaining positioning precision while still achieving reliable locking.
2Reliability
If the locking screw directly jacks the lifting slide rail, then the locking function is achieved, but the service life of the lifting slide rail is shortened
Solution Approach 1:
The locking block acts as a protective intermediary that absorbs the mechanical stress and contact wear. Instead of the locking screw directly jacking the lifting slide rail and causing depression and wear, the locking block contacts the slide rail surface, significantly reducing wear and extending the service life of the lifting slide rail while maintaining the locking function.
3Reliability
If the locking screw directly jacks the lifting slide rail, then the locking function is achieved, but sliding smoothness is reduced
Solution Approach 1:
The locking block serves as a smooth-contact intermediary between the locking mechanism and the lifting slide rail. Its design ensures plane contact with the slide rail surface, eliminating the depression and rough contact caused by direct locking screw engagement. This maintains sliding smoothness while achieving reliable locking through the locking block's interaction with the slide rail.

AI summary
The present invention discloses a laser module lifting apparatus with a protecting function. The apparatus comprises a slide block for being fixedly connected with a laser module. The slide block is provided with a sliding groove, and the sliding groove is provided with a lifting slide rail in a liftable manner. A locking block is arranged between the lifting slide rail and an inner side wall of the sliding groove, and a side of the locking block away from the lifting slide rail is provided with a locking screw. By arranging the locking block at a locking end of the locking screw, a conventional way of jacking the lifting slide rail directly by using the locking screw is converted into a way of jacking the lifting slide rail by the locking block.
