Roller pin type self-locking one-way-overturning device for double-layer hollow glass built-in shutter
The invention discloses a roller pin type self-locking one-way-overturning device for a double-layer hollow glass built-in shutter, and belongs to the technical field of sunshade hollow glass products. The roller pin type self-locking one-way-overturning device comprises an overturning wheel and a roller pin driving shaft. A roller pin driving shaft matching hole is formed in the center of the overturning wheel. The roller pin driving shaft is inserted into the roller pin driving shaft matching hole to be matched with the overturning wheel. The roller pin type self-locking one-way-overturning device is characterized in that an overturning shaft fixing hole is formed in the axial middle of the roller pin driving shaft, a first roller pin driving boss and a second roller pin driving boss are formed on the surface of the roller pin driving shaft, the driving bosses are spaced by 180 degrees in the circumferential direction of the roller pin driving shaft to form the face-to-face position relationship, a first roller pin movement groove and a second roller pin movement groove are formed between the first roller pin driving boss and the second roller pin driving boss, a first roller pin is arranged in the first roller pin movement groove, a second roller pin is arranged in the second roller pin movement groove, a first arc-shaped transition flange is formed in the middle of the bottom wall of the first roller pin movement groove, and a second arc-shaped transition flange is formed in the middle of the bottom wall of the second roller pin movement groove. Friction damage, caused by a pulling rope, to the overturning wheel can be avoided, and meanwhile the overturning wheel and the pulling rope can be prevented from being abraded.
