In order to make the above adjustment process more stable and reliable, the number of adjusting screws 31 can be set to at least two, and the two adjusting screws 31 can be arranged at intervals along the extension direction of the guide rail assembly 2. In which, the extension direction of the guide rail assembly 2 can correspond to the front-back direction of the refrigerator.
[0036] In some embodiments provided in the present disclosure, reference Figure 1 , Figure 3 , Figure 4 as well as Figure 5As shown in , at least part of the first bracket 11 is arranged above the guide rail assembly 2, and the part of the first bracket 11 arranged above the guide rail assembly 2 has a threaded hole 32, so that the upper and lower intervals between the first bracket 11 and the guide rail assembly 2 can be adjusted by adjusting the extension length of the adjusting screw 31 between the threaded hole 32 and the guide rail assembly 2, and because the guide rail assembly 2 is slidably connected to the box body, the guide rail assembly 2 is fixed in the upper and lower directions, and the first bracket 11 moves up and down relative to the guide rail assembly 2 with the rotation of the adjusting screw 31. Among them, arranging the first bracket 11 above the guide rail assembly 2 can enable the door body to be supported on the guide rail assembly 2 through the first bracket 11, thereby facilitating the assembly of the drawer adjustment device and the refrigerator. And opening the threaded hole 32 on the first bracket 11 located above the guide rail assembly 2 can facilitate the operator to operate the adjusting screw 31, thereby facilitating the adjustment of the installation height of the bracket assembly 1.
