Technical Field
[0001] The present invention relates to the technical field of shower doors, and more particularly
to a lower sliding device in a shower door.
Background Technology
[0002] The existing sliding shower doors are usually provided with upper and lower tracks
and movable door sheets, wherein a sliding groove is provided on one side of the lower
track, and upper and lower pulleys are mounted on the movable door sheets, and the
pulleys can slide on the lower track, there is a certain distance between the movable
door sheets and the lower track during sliding along the lower track. On one hand,
since the sliding groove is located on the side of the lower track, when the user
looks outward from the shower door, it is possible to see the sliding groove of the
lower track and the sliding wheels, which has an influence on the aesthetics; On the
other hand, the shower door needs to be cleaned in a timely manner, and in the existing
shower door structure, since it is troublesome to separate the lower track from the
movable door sheets, it is more difficult to clean the fouling dirt between the lower
track and the movable door sheets.
