Abstract

The invention discloses a core-moving self-release upper pulley. The core-moving self-release upper pulley comprises a base frame, wherein a slip shaft is arranged on the base frame; the base frame and a rotary plate are connected through an unfolding spring; the two ends of the rotary plate are equipped with roller wheels; a slip slot is formed in the slip shaft; a slip block is arranged in the slip slot; a locking table is arranged on the slip block; a locking notch matched with the locking table is formed in a shaft hole; a clearance section is arranged on the slip section; a slip gap is formed in the slip slot; and the slip gap is formed in the lower portion of the slip block. In use, the core-moving self-release upper pulley is mounted in an upper door window while the locking table is connected with the locking notch, the rotary plate is mutually locked with the slip shaft, the rotary plate does not rotate around the slip shaft, a door window is lifted upwards and a guide rail slot is in mutual collision with the upper end of the slip block, so that the slip block moves downwards, and the locking table is separated from the locking notch for enabling the rotary plate to rotate around the slip shaft; and the two ends of the rotary plate separately extend out of front and rear sides of the base frame, and the roller wheels abut against the vertical wall of the guide rail slot, so that automatic release is realized. The core-moving self-release upper pulley is used for door and window fittings.

Description

technical field [0001] The invention relates to the field of door and window accessories, in particular to a core-moving self-releasing upper pulley. Background technique [0002] Existing doors and windows slide in the guide rail groove, and it is necessary to set upper pulleys on the upper door and window frame. In order to adapt to guide rail grooves of different widths, the upper pulley includes a base frame arranged left and right, and a rotating plate is arranged on the base frame. There are two rollers at both ends, and then the angle between the base frame and the rotating plate is adjusted through a rigid mechanical adjustment structure, so as to control the distance of the two rollers protruding out of the base frame, so that it can adapt to different widths. rail groove. However, since the upper door and window frame is located at a higher position, it is very laborious to adjust. Contents of the invention [0003] The technical problem to be solved by the pre...
