Detailed Description
The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
A three-rail outer frame of a very narrow sliding door is shown in figures 1-2 and comprises a door frame 1 and a door leaf combination 2 movably arranged in the door frame 1; the door frame 1 comprises an upper door frame slide 11 above the door leaf assembly 2 and a lower door frame slide 12 below the door leaf assembly 2. The upper surface of the doorframe lower sliding piece 12 is provided with three sliding rail combinations 121; the door leaf assembly 2 comprises a first door leaf 21, a second door leaf 22 and a third door leaf 23; the bottoms of the first door leaf 21, the second door leaf 22 and the third door leaf 23 are all provided with a sliding combination 201.
As shown in fig. 3 to 4, the sliding rail assembly 121 includes a pulley guide 1211 formed by recessing the upper surface of the door frame lower slide 12, a sliding bar 1212 formed by protruding the upper surface of the door frame lower slide 12 upward and located at both sides of the pulley guide 1211 and arranged in parallel, and a sealing layer 1213 disposed on the outer surface of the sliding bar.
