摘要： Disclosed is a sliding window emergency opening system, comprising: an emergency opening device (2) and a general opening control device (3); wherein a first rotary shaft (202) in the emergency opening device is rotatably mounted on a first base (201); a first pulling cable (206) is wound around the first rotary shaft (202), and one end thereof is connected with a movable sash of the sliding window (1); a first ratchet (203) is fixedly connected with the first rotary shaft (202); a first elastic component is compressed to make a first pawl (204) abut against the first ratchet (203); a second rotary shaft (302) in the general opening control device (3) is rotatably mounted on a second base (301); one end of a general control pulling cable (303) is connected with the second rotary shaft (302), and the other end is connected with the first pawl (204); when the second rotary shaft (302) rotates, the general control pulling cable (303) is wound up to make the first pawl (204) detached from the first ratchet (203); under the action of the gravity of the movable sash in the sliding window, the first pulling cable (206) drives the first rotary shaft (202) to rotate so as to open the movable sash. In practical application, the general opening control device (3) may be provided at a location far from the emergency opening device (2), and the emergency opening device may be remotely controlled to open the movable sash.

摘要： This application provides a vertical sliding window, including horizontal frame side edges, vertical frame side edges, and an opening sash, wherein the opening sash slides up and down along a guide rail on the vertical frame side edge. In addition, the vertical sliding window further includes a balance weight device and a balance weight traction cable. The balance weight device includes an enclosure, a rotating shaft partially disposed within the enclosure, a spiral spring whose two ends are respectively fixedly connected to an inner wall of the enclosure and the rotating shaft, and a cone pulley fixedly connected to the rotating shaft, wherein a tapered surface of the cone pulley is provided with a spiral groove. A lower end of the balance weight traction cable is fixedly connected to the opening sash, and an upper end thereof is fixedly connected to the cone pulley. When the opening sash moves from bottom to top, an elastic deformational force generated by the spiral spring enables the balance weight traction cable to be gradually wound into the spiral groove, and the elastic deformational force of the spiral spring is gradually reduced. Due to a mutual conversion between elastic potential energy of the spiral spring and gravitational potential energy of the opening sash, in the vertical sliding window provided in this application, an external acting force for dragging the opening sash to move up and down as well as energy consumption may be reduced.
