[0013] The beneficial effects of this utility model are as follows:

[0014] This invention addresses the problem of existing elevator pulley protective covers being bolted to the pulley mounting base. The use of a baffle to restrict the position of the fixed plate allows the fixed plate to press against the baffle during installation, moving it further into the second square groove. As the fixed plate passes the baffle, a spring extends, returning the baffle to its initial position, thus moving the baffle to the top of the fixed plate and blocking its position. This effectively solves the problem mentioned in the background art, where most existing elevator pulley protective covers are bolted to the pulley mounting base. This requires removing the cover for pulley maintenance, and bolting necessitates tools for installation and removal, which is time-consuming and labor-intensive, increasing maintenance complexity and time costs, especially in cases of frequent inspections or repairs. This invention simplifies operation, facilitates installation and removal of the protective cover, effectively reduces operational difficulty, minimizes the time and effort required for installation and removal, and improves work efficiency.
