DOOR/WINDOW PULLEY, PULLEY DEVICE, AND DOOR/WINDOW
The present disclosure relates to a field of door/window hardware accessories, in particular to a door/window pulley, a pulley device, and a door/window. The present disclosure provides a bearing and an anti-deformation metal ring that can be in contact with a track, the anti-deformation metal ring uses its own rigidity to effectively avoid generating indentation, and the door/window pulley is also difficult to be pressed to cause deformation. Moreover, an inner part of an injection molded body is disposed between the bearing and the anti-deformation metal ring, which not only well transfers pressure bore by the anti-deformation metal ring when load-bearing to the bearing, but also restores the anti-deformation metal ring after slight deformation by giving an outward elastic support to the anti-deformation metal ring using elasticity of the injection molded body.
