An easy-to-maintain pulley structure

Abstract

This utility model discloses a pulley structure that is easy to maintain, relating to the field of pulley structure technology. A connecting shaft is provided at the bottom of the fixed frame, and a sliding mechanism is installed at the bottom of the connecting shaft. The sliding mechanism includes a connecting frame, which is fixedly connected to the connecting shaft. A fixed plate is installed at the bottom of the connecting frame, and a positioning groove is provided between the connecting frame and the fixed plate. The connecting frame is connected to a positioning frame through two sets of positioning grooves, and a pulley body is installed on the outside of the positioning frame. A limiting mechanism is provided inside the fixed frame, and the limiting mechanism includes a connecting damper. A fitting block is installed at the bottom of the connecting damper, and limiting frames are provided on both sides of the connecting damper. When disassembling one set of pulley bodies, the connection between the positioning frame and the positioning groove can be disconnected, and then the connecting damper presses down on the fitting block and the limiting frame, causing the fitting block to fit and fix with the track. At the same time, the limiting frame limits and fixes the other pulley bodies. The limiting mechanism supports and fixes the pulley structure, avoiding the need to disassemble and maintain the entire pulley structure.
