The two support wheels on the support plate clamp the third support bar at the bottom of the guide rail again, thereby realizing rapid adaptive limit locking of the movable door. The structure is simple, and there is no need to manually adjust the locking limit component. Similarly, the second clamping guide frame presses the inner wall of the double-layer fixed door tightly, thereby realizing rapid adaptive limit locking of the movable door. The structure is simple, and there is no need to manually adjust the locking limit component. The cooperation between the first clamping guide frame and the second clamping guide frame can effectively ensure the safety and stability of the track sliding door.
