Background

At present, when people decorate houses, a shower cabin is usually disposed in a bathroom, and a shower door with a glass sheet is usually used for a common shower cabin. There are typically two types of movable doors serving as the shower door: a sliding door that translates laterally and a pivoting door that is rotatable about a rotating shaft.
The pivoting door typically has a metal frame comprising two side edges, with a glass sheet disposed between the two side edges. The shower door is usually provided with a frame fixed to a wall, and the pivoting door comprising the glass sheet is fixed to the frame, thereby fixing the glass sheet and the frame. In general, the rotating shaft is disposed on the pivoting door, the glass sheet is fixed on the rotating shaft, and the pivoting door can rotate around the rotating shaft, so as to achieve the opening and closing of the pivoting door.
An opening and closing door is provided with a frame made of metal leaning against a wall, the frame leaning against the wall is connected with one side of the fixed door, and the other side of the fixed door is connected with a vertical frame. One side of the movable door is provided with a vertical metal rotating shaft, and the movable door can rotate relative to the fixed door around the rotating shaft.
In order to achieve the rotation of the movable door, the metal rotating shaft on the movable door usually leans against one side of the fixed door with the vertical frame, upper ends and lower ends of the metal rotating shaft and the vertical frame are respectively provided with a fixed rotating shaft seat to integrally connect the fixed door with the movable door, and the movable door can rotate around the rotating shaft, thereby achieving the opening and closing of the movable door. Due to the relatively great weight of the movable door, a relatively large force is usually required to open and close the movable door. However, due to the fact that the movable door is great in weight and relatively large in inertia, when the movable door is closed to a limit position, the movable door can impact the frame or a limiting piece to greatly impact the movable door, the frame and the limiting piece; if an impact force is relatively large, the movable door may be broken or the frame and the limiting piece may be damaged, so that the use of the shower door may be influenced.
