The first upper horizontal plane 6 and the second upper horizontal plane 301 are both upward facing horizontal planes, i.e. the upper guide rail 2 and the lower guide rail 3 are used for rolling fit with the upper horizontal roller 401 and the lower horizontal roller 501 respectively, and are also used for bearing the gravity of the L-shaped door body 1. Because the matching surfaces of the upper vertical roller 402 and the lower vertical roller 502 and the upper guide rail 2 and the lower guide rail 3 face opposite, after the sliding door is assembled, the upper vertical roller 402 and the lower vertical roller 502 form an axial limiting pair with the upper guide rail 2 and the lower guide rail 3, and the axial direction refers to the axial direction of the upper horizontal roller 401 and the lower horizontal roller 501, and the upper horizontal roller 401 and the lower horizontal roller 501 cannot axially displace, so that the abrasion of the roller 5013 and the sliding door is reduced.
