DOOR AND WINDOW ROLLER, ROLLER APPARATUS, AND DOOR AND WINDOW
A door/window pulley, relating to a field of door/window hardware accessories, which can effectively avoid generating indentation by providing a bearing (1) and an anti-deformation metal ring (2) that can be in contact with a track and using the own rigidity of the anti-deformation metal ring (2), such that the door/window pulley is also difficult to be pressed to cause deformation. Moreover, an inner part of an injection molded body (3) is disposed between the bearing (1) and the anti-deformation metal ring (2), which not only well transfers pressure bore by the anti-deformation metal ring (2) when load-bearing to the bearing (1), but also restores the anti-deformation metal ring (2) after slight deformation by giving an outward elastic support to the anti-deformation metal ring (2) using elasticity of the injection molded body (3). A track groove (31) is disposed on a periphery of the injection molded body (3), and the anti-deformation metal ring (2) is disposed on a bottom of the track groove (31), so that when the door/window pulley moves on the track (5), bearing force directly acts on the anti-deformation metal ring (2), and friction between the door/window pulley and the track (5) occurs between a side wall surface, of the track groove (31) of the injection molded body (3), and the track (5), which effectively reduces generation of noise.
