Abstract

This utility model discloses a quick-release and locking mechanism for a cover plate, comprising: a cover plate with a central hole extending through its center; a positioning structure symmetrically connected to both ends of one side surface of the cover plate; positioning components symmetrically connected to the upper and lower sides of the center of one side surface of the cover plate; a locking plate engaged between the upper and lower positioning components; and a locking bolt passing through the central hole and threadedly connected to the locking plate. An observation groove is also provided through the cover plate. This utility model features a simple structure and convenient assembly / disassembly, improving maintenance efficiency and meeting protection requirements. It also solves the problems of difficult maintenance and low assembly / disassembly efficiency associated with traditional cover plate locks. Furthermore, it offers the triple advantages of maintenance-free operation, quick assembly / disassembly, and anti-displacement stability, making it particularly suitable for the protection of industrial equipment requiring frequent maintenance.
