Abstract
Description
Technical field
[0001] The present utility model relates to the technical field of bathroom hinges, in particular a dampened glass door fitting for bathrooms. State of the art
[0002] Glass door fittings for bathrooms are hardware components used to clamp glass doors and ensure their smooth operation. They are widely used in glass doors and windows, bathroom doors, and shower enclosures. Glass door fittings with a soft-close mechanism allow for flexible opening and rotation of the glass door and can automatically return to their original position, keeping the glass door closed.
[0003] Glass door fittings for bathrooms mainly comprise a fixed plate, a movable plate, and a pivot axis, whereby the fixed plate and the movable plate are rotated by the pivot axis; currently, there are two problems with glass door fittings for bathrooms: 1. The two ends of the pivot axis are largely attached to the movable panel by keyway connections. This design does not allow for adjustment of the angle between the fixed and movable panels after closing. When installed on sloping walls or uneven wall surfaces, the glass door cannot be fully closed or open, resulting in angular deviations and preventing the shower glass doors from closing completely. 2. When closing the glass door, due to the high speed, the glass door has to be opened and closed several times before it gradually comes to rest quietly in the closed position, which leads to increased wear and tear on the internal parts of the glass door fitting and shortens its service life.
