Description

A Compensatory Invisible Opening and Closing Mechanism

Technical field:

The utility model relates to an opening and closing mechanism, in particular to a compensation type invisible opening and closing mechanism.

Background technique:

The opening and closing mechanism is used to connect two relatively rotating objects and allow the mechanical device to rotate between them. Most of the existing opening and closing mechanisms are hinges, and the commonly used opening and closing mechanisms are mostly used for doors and windows. The door and window hinge is to realize the opening and closing of the door and window by fixing one side of the hinge on the frame of the door and window, and the other side is fixed with the door or window sash, and the rotation axis of the circle center is outside the door or window. The existing hinges have the following defects: 1. Unsightly: because the rotating shaft of the center of the circle is exposed outside, the aesthetics of the overall door and window is greatly reduced; 2. Not anti-theft: the exposed rotating shaft of the center of the circle is easily damaged; 3. The door frame Large gap: Since the door rotates with the outer rotation axis as the center of the circle, and the door has a corresponding thickness, there must be a corresponding size gap between the door frames, which destroys the overall aesthetic feeling; 4. Poor sound insulation effect: due to the corresponding gap between the door frames 5. Waste of raw materials: The opening of the window is also centered on the rotating shaft exposed on the outside of the window, so the thickness of the opening and closing window is obviously thicker than that of the non-opening and closing window, and the opening and closing window is closed at the same time. If the time seal is better, the opening and closing windows must be heightened and widened, and the material waste is serious and not energy-saving; 6. Traditional hinges do not have the function of cushioning and suction. Therefore, it is very necessary to design a compensation type invisible opening and closing mechanism that is elegant in appearance, safe and anti-theft, economical and practical.
