One. What principles are applied in sliding doors?
To understand the working principle of sliding doors, it is first necessary to understand its structure. A sliding door typically consists of a door leaf, door frame, side seals, handles, locks, upper and lower tracks, and pulleys. The pulleys and tracks are the most critical metal components, and their quality determines the smoothness and stability of the sliding door. Because sliding doors primarily rely on the pulleys under the door leaf and the ground tracks as their movement path, the quality of the ground tracks and pulleys directly affects the lifespan of the sliding door.
Two. Is the sliding door a sliding or rotating phenomenon?
The movement of sliding doors is linear.
平移，是指在同一平面内，将一个图形上的所有点都按照某个直线方向做相同距离的移动，这样的图形运动叫做图形的平移运动，简称平移。
- Translate the shape and size of the figure without changing it. When a figure is translated, the corresponding line segments are equal, the corresponding angles are equal, and the line segments connecting corresponding points are equal. This is an isometry, and a type of affine transformation in the affine space. It can be viewed as adding the same vector to each point, or as moving the center of the coordinate system. In other words, if a known vector and a point in space are translated.
Sliding doors, which maintain their shape and size while moving, represent a translation (shift) phenomenon. In contrast, swinging doors, revolving doors, and similar mechanisms represent a rotation phenomenon.
