[0002] For the common single curtain track on the market, when two curtains are pulled together, it is difficult to fit the two curtains tightly together, and light is easily leaked. To solve the above problem, the Chinese patent with publication number CN213488277U discloses a light leakage-proof telescopic window track, which includes two main tracks in the same straight line, and a secondary track arranged at the end of the main track and parallel to the main track. The two secondary tracks are at the same horizontal height and form an overlapping area; it also includes a pulley slidably embedded in the main track and the secondary track, a hanging ring arranged on the pulley, and a mounting mechanism arranged on the main track and the secondary track for locking it on the top of the wall. This solution not only makes it difficult for light to leak after the two curtains are combined, but also expands the scope of application of the window track, which greatly improves the user experience.

[0003] However, at the overlapping point of the two auxiliary rails mentioned in the above patent scheme, the distance between the two auxiliary rails is not easy to control. If the distance is too large, the two main rails are not in the same straight line, light leakage will occur at the overlapping point, and a wider installation space will be required, which will also affect the appearance of the curtain after installation; if the distance is too small, the curtain will experience greater friction during movement, affecting the normal opening and closing of the curtain.
