Eccentric pulley capable of bearing stretch bending heavy load and preventing rope from falling off

The eccentric pulley comprises a suspension shaft, a through hole is formed in the central axis of the suspension shaft, and a bottom plate is fixedly installed at the top end of the suspension shaft through a suspension shaft screw; a pulley supporting mechanism is fixedly installed on the top face of the bottom plate, a pulley is rotationally connected to the pulley supporting mechanism, and the pulley is eccentrically arranged. The aircraft model suspension device can be used in a heavy load environment, can prevent the rope from falling off, and can adapt to the attitude change of an aircraft model. 本发明公开了一种能够承受拉弯重载并防止绳索脱落的偏心滑轮，包括悬挂轴，悬挂轴中心轴线开设有通孔，悬挂轴顶端通过悬挂轴螺钉固定安装有底板；底板顶面固定安装有滑轮支撑机构，滑轮支撑机构上转动连接有滑轮，滑轮偏心设置；底板底面设有悬挂机构，悬挂机构转动套设在悬挂轴外壁，本发明可以使用于重载环境，并可以防止绳索脱落，并能够适应飞行器模型姿态变化。
