The invention discloses an installation-free fast-height-adjusting guide rail pulley. The installation-free fast-height-adjusting guide rail pulley comprises a left-right arranged base frame and a spring set, and the spring set comprises a support spring; the base frame is provided with a top plate, a front vertical plate, a rear vertical plate and a right vertical plate, a spacer plate is arranged below the top plate, an adjusting gap is formed between the top plate and the spacer plate, and a height-adjusting gap is formed between the front vertical plate and the rear vertical plate; and a height-adjusting plate is provided with an idler wheel shaft, the right vertical plate is provided with a threaded hole, the threaded hole is internally provided with an adjusting screw, an adjusting push block is connected with the tail end of the thread section of the adjusting screw, and the two ends of the support spring are connected with the adjusting push block and the idler wheel shaft correspondingly. The adjusting push block is driven to move to the left, so that a bevel pushes the starting end of the support spring to move, in this way, the middle section of the support spring tightly presses the side wall of a door and window frame, so that fixing of the base frame and the door and window frame is achieved, when the adjusting push block is driven to continue to move to the left,the tail end of the support spring moves downward, so that the idler wheel shaft moves downward, and the height-adjusting function is achieved. The installation-free fast-height-adjusting guide railpulley is applied to door and window fittings.
Description
technical field [0001] The invention relates to the field of door and window accessories, in particular to a quick height adjustment guide rail pulley without installation. Background technique [0002] In the existing guide rail pulley, the base frame should be connected with the door and window frame first, and then the height of the roller frame should be adjusted.
