Description

Movable pulley guide system Technical Field The utility model relates to the technical field of lifting window accessories, in particular to a movable pulley guide system. Background A window lifter is a window that can be opened and closed, and is generally composed of an upper part and a lower part. The opening and closing of the window can be realized by means of up-and-down movement, usually by manual operation or motor control. A window type, which is designed for convenience of ventilation and lighting, is commonly used in buildings. Such a window is generally more convenient than a conventional sliding window because it can more easily control the opening and closing of the window. The prior rail-changing lifting window guide system adopts a pulley and guide rail mode to realize rail changing, such as a fixed frame section bar of a sliding vertical window with double slide ways in patent ZL201420089654.1, belonging to a fixed frame section bar of a sliding vertical window. The two L-shaped slide rail assemblies are fixedly connected with the frame section bar through screws respectively, slide rail parts of the two slide rail assemblies are mutually parallel, the lower part of one slide rail assembly is positioned at the outer side of the upper part of the other slide rail assembly, and each slide rail assembly has the same structure. As shown in fig. 1 and 5, the pulley 5 on the upper side of the sliding window sash 4 is positioned in the high-position slideway combination body, and the pulley on the lower side of the sliding window sash is positioned in the low-position slideway combination body, so that the sliding window sash and the lower fixed window sash are parallel to move on two planes but are not contacted when being opened, and the sliding window sash and the lower fixed window sash are in the same plane when being closed. The relative positions of the pulleys and the lifting fan of the system can be adjusted up and down, and the mode leads the variable track distance of the track to be consistent with the variable track distance of the opening fan for completely opening and closing so as to realize the normal opening and closing function of the lifting window. Disclosure of utility model (One) solving the technical problems In order to overcome the defects in the prior art, the utility model provides a movable pulley guide system which solves the problems in the prior art. (II) technical scheme The movable pulley guide system is applied to a lifting window, the lifting window is lifted in a window frame, the movable pulley guide system further comprises an upper guide pulley assembly, a lower guide pulley assembly and a corresponding set of rails, one set of rails is arranged on the inner side of the window frame, a rail changing area is arranged at the upper end of each rail, one set of guide pulley assemblies are respectively arranged at the upper end and the lower end of the lifting window, one end of each guide pulley assembly is hinged to the side edge of the lifting window, pulleys are arranged at the other end of each guide pulley assembly, the pulleys are connected to the corresponding rails in a sliding mode, and the lifting window is lifted along the rails through the guide pulley assemblies to realize rail changing opening and closing.
