[0002] A sliding door refers to a door whose door leaf is connected to a pulley and is movable on a fixed track. It is also called a push-pull door. It is different from a hinged door whose door leaf is connected with a hinge. A sliding door has the characteristics of easy installation, reusability, industrial production, production in small workshops, fire prevention, and environmental protection. When installing a sliding door, the bottom of the sliding door is generally connected to a guide rail, and the sliding door is pushed and pulled horizontally by sliding on the guide rail. During the movement of the sliding door, when the sliding door is stationary, it is difficult for the sliding door to remain stable on the guide rail due to the small friction between the sliding door and the guide rail.
