The invention relates to the technical field of door and window accessories, in particular to a pulley assembly and a door and window. The pulley assembly comprises a connecting base, pulley modules oppositely arranged on the connecting base and a sliding piece connected in the connecting base in a sliding mode, a limiting hole is formed in the connecting base, a threaded hole coaxial with the limiting hole is formed in the sliding piece, a threaded rod is rotationally arranged in the limiting hole, and the threaded rod is connected with the sliding piece in a threaded mode. A threaded hole is formed in the sliding part, the threaded rod is connected with the sliding part in a threaded mode through the threaded hole, a protruding edge corresponding to the door and window sash body and a wedge-shaped protruding block corresponding to the sliding part are arranged on the connecting base, and when the threaded rod drives the sliding part to slide along the connecting base, the wedge-shaped protruding block abuts against the protruding edge. The sliding piece can abut against the wedge-shaped protruding block to protrude out of the connecting base so that the protruding edge can abut against and be locked with the door and window sash body in the direction perpendicular to the sliding direction of the sliding piece. By the adoption of the mode, the probability that abnormal sound is generated due to loosening of the screws can be reduced, and the use stability can be improved.
本发明涉及门窗配件技术领域，具体涉及一种滑轮组件及门窗。滑轮组件包括：连接座、在连接座上相对设置的滑轮模组，以及在所述连接座内滑动连接的滑动件，所述连接座上设置有限位孔，所述滑动件上设置有与所述限位孔同轴的螺纹孔，所述限位孔内转动设置有螺杆，且所述螺杆通过所述螺纹孔与所述滑动件螺纹连接，所述连接座上设置有与所述门窗扇体对应的凸沿，以及与所述滑动件对应的楔形凸块，所述螺杆带动所述滑动件沿所述连接座滑动时，所述滑动件能够与所述楔形凸块抵持而凸出所述连接座，以使所述凸沿朝向垂直于所述滑动件滑动方向与所述门窗扇体顶压锁定。采用上述方式，能够降低因螺丝松动产生异响的几率，有利于提升使用时的稳定性。
