Description

Technical Field

[0001] This utility model relates to the field of anti-loosening bolt technology, specifically an anti-loosening bolt for heavy-duty shelves. Background Technology

[0002] Anti-loosening bolts maintain fastening force under complex working conditions such as vibration, impact, or temperature changes through special structural designs (such as nylon inserts, double nuts, spring washers, or thread sealant pre-coating) or mechanical locking mechanisms (such as wedge gaskets or flange face grooves), preventing safety hazards caused by loosening of the connecting parts.

[0003] Existing heavy-duty shelving uses partial anti-loosening bolts (such as adhesive-type or nylon lock nuts). Due to the enclosed structure or reliance on disposable locking materials, checking for loosening requires complete disassembly to observe internal wear, adhesive failure, or insert deformation. This results in a cumbersome and time-consuming maintenance process that can easily damage the original anti-loosening structure, leaving room for improvement. Utility Model Content
