A water trough 3 is provided on the periphery of the door bottom frame, a drain pipe 4 is provided in the water trough to connect to the drainage place, a cover plate 51 is provided on the door bottom frame, a drainage cover plate 53 is provided on the drainage trough, and the drainage cover plate is provided with a water inlet hole 531. Based on actual needs, the accumulated water is mainly rainwater on rainy days, and the water trough and the drainage cover plate are arranged on the outdoor side of the door bottom frame. There are multiple water inlet holes on the drainage cover plate in an array. The top surface of the drainage cover plate is lower than the cover plate or the ground paving material, and a support bar 532 is provided on the top surface of the drainage cover plate, such as Figure 3 shown.

[0025] In order to make full use of the outer wall of the door bottom frame, a side wall is omitted on the side of the outer wall of the sink close to the door bottom frame, and the two are connected and sealed at the bottom. The top opening width of the sink does not need to be too large to affect the threshold width, but the water storage cavity inside the sink needs to retain a certain volume, so part of the bottom paving material covers the top of the sink, such as Figure 1 As shown. Thus, the following structure is formed. The side wall of the door bottom frame and the water tank wall form a water storage cavity of the water tank, and the drainage cover plate is movably plugged into the upper opening of the water tank, one end of the drainage cover plate is connected to the water tank wall, and the other end of the drainage cover plate is connected to the cover plate arranged on the side wall of the door bottom frame.

[0026] In order to facilitate the movable connection and stability of the drainage cover plate, and to cover the laying gap between the external floor material 6 and the sink, the sink wall is close to the ground or the floor laying material, and the edge of one end of the drainage cover plate is folded and extended horizontally to cover the gap between the sink wall and the floor laying material and form a connection; the cover plate is provided with a connecting part for connecting the drainage cover plate, and the connecting part is provided with a groove, and the groove and the other end folded edge of the drainage cover plate constitute the movable plug-in structure.

[0027] In order to prevent water seepage from the bottom, the solution is further optimized, and a pad 7 is provided at the bottom of the door frame and the sink. Considering that the sink and the drainage cover are arranged on the outdoor side of the door frame, the pad is arranged in an L-shaped cross section, that is, folded up on the indoor side and close to the outside of the door frame. The pad can be made of stainless steel. The pad makes the overall load-bearing more uniform. Example 2

The movable mechanism includes a pulley bracket 81, a pulley 82, and a bottom profile 83. The pulley bracket is installed on the door bottom frame, the pulley is located in the pulley bracket, the bottom profile is connected to the door leaf on the top, and the pulley is connected to the bottom profile on the bottom; the cover plate is connected to the side wall of the door bottom frame, and a gap is provided between adjacent cover plates for the bottom profile to move. The cover plate with a connecting portion connected to the drainage cover plate is defined as an outer cover plate 52, such as Figure 1 , Figure 2 The bottom profile has an I-shaped cross section, a receiving groove is provided on the bottom profile to connect the door leaf, and a pad 84 corresponding to the pulley is embedded under the bottom profile. The figure shows a double door and double track. Example 3

[0029] On the basis of Example 2, in order to prevent the sliding door from shifting during movement, the following structure is designed: a rotatable positioning wheel 85 is provided on the center line of the slide rail bracket, and a positioning strip 86 that slidably cooperates with the positioning wheel is installed under the bottom profile; the bottom surface of the positioning strip that cooperates with the positioning wheel is a V-shaped structural surface, and the positioning wheel has a V-shaped groove that cooperates with the V-shaped structural surface; a corresponding V-shaped avoidance groove 87 is provided on the pulley bracket.
