Title: VERTICAL SLIDING WINDOW
Abstract:
A vertical sliding window, comprising a horizontal frame (11), a vertical frame (12), and an sash (2); the sash (2) slides up and down along a re-directionable guide rail (13); the vertical sliding window further comprises a weight device (3) and a weight traction cable (4); the weight device (3) comprises a housing (31), a rotary shaft (32) which is partially provided in the housing (31), a spiral spring (34) of which two ends are respectively fixedly connected to the inner wall of the housing (31) and the rotary shaft (32), and a cone pulley (33) which is fixedly connected to the rotary shaft (32); the cone-shaped surface of the cone pulley (33) is provided with spiral grooves (331); the lower end of the weight traction cable (4) is fixedly connected to the sash (2), and the upper end of the weight traction cable (4) is fixedly connected to the cone pulley (33); when the sash (2) moves upwards, an elastic deformation force generated by the spiral spring (34) enables the weight traction cable (4) to gradually wind around the spiral grooves (331), and the elastic deformation force of the spiral spring (34) gradually decreases. The vertical sliding window reduces the amount of external force and energy consumption needed to pull the sash (2) in the vertical direction.
