[0049] Specifically, please continue to refer to Figures 8-12 , in one embodiment, the first adjusting structure 30 includes a first adjusting block 33 and a first eccentric wheel 34. The first end 35 of the first eccentric wheel 34 passes through the first fixing bracket 23 and is combined with the first adjusting block 33. The second end 36 of the first eccentric wheel 34 passes through the first bracket 241 and is fixed to the cabinet door panel 2. The first eccentric column 37 of the first eccentric wheel 34 is located in the first elongated hole 25. Here, the first end 35 of the first eccentric wheel 34 corresponds to the fixed end of the first adjusting structure 30, and the first adjusting block 33 corresponds to the adjusting end of the first adjusting structure 30.

[0050] The second adjustment structure 40 includes a second eccentric wheel 41 and a first bolt. The second eccentric column 43 of the second eccentric wheel 41 passes through a first through hole 26 on the second bracket 242. A protrusion structure 44 is provided on a side of the second eccentric wheel 41 opposite to the second eccentric column 43. The second eccentric wheel 41 is positioned with a first positioning portion 11 on the refrigerator door body 1, and the protrusion structure 44 protrudes from a second positioning hole on the first positioning portion 11. The first bolt passes through the second strip-shaped long hole 27 and is locked to the refrigerator door body 1. The first positioning portion 11 is, for example, a side wall of the refrigerator door body 1. The first bolt includes a matching stud 421 and a nut 422. The stud 421 passes through the second strip-shaped long hole 27 and a fixing hole on the refrigerator door body 1 in sequence and then is screwed with the nut 422 to clamp and fix the second bracket 242. Here, at the joint of the bracket structure 20 and the refrigerator door body 1, the first bolt is reversed to fix the cabinet door panel. Moreover, after the adjustment box device is installed between the refrigerator door body and the cabinet door panel, the protrusion structure 44 will be exposed from the second positioning hole on the first positioning portion 11 to facilitate the rotation adjustment of the second eccentric wheel 41, and the nut 422 of the first bolt will also be exposed from the installation hole on the first positioning portion 11 to facilitate the tightening adjustment of the first bolt.

[0051] Please continue to refer to Figure 6 、 Figure 7B and Figure 8 , the third adjustment structure 50 includes a third eccentric wheel 51 and a third adjustment block 52. The first end 511 of the third eccentric wheel 51 passes through a through hole 233 on the first fixing bracket 23 and is combined with the third adjustment block 52. The second end 512 of the third eccentric wheel 51 passes through the first bracket 241 and is fixed to the cabinet door panel 2. The third eccentric column 53 of the third eccentric wheel 51 is located in the third strip-shaped long hole 28.

[0052] In the second combination area 200, the second bracket 242 is further provided with a fourth strip-shaped long hole 29 along the second direction D2. The third adjustment structure 50 further includes a second bolt 54. The second bolt 54 passes through the fourth strip-shaped long hole 29 and is locked to the refrigerator door body 1 (such as the first positioning portion 11). Here, at the joint of the second bolt 54 and the fourth strip-shaped long hole 29, the second bolt 54 is also reversed to achieve fixation. Moreover, after the adjustment box device is installed between the refrigerator door body and the cabinet door panel, the nut of the second bolt 54 will also be exposed from the installation hole on the first positioning portion 11 to facilitate the tightening adjustment of the second bolt.

[0053] Specifically, the first eccentric wheel 34 includes a first eccentric wheel body 341, a first shaft located at the first end 35 of the first eccentric wheel 34, and a second shaft located at the second end 36 of the first eccentric wheel 34. The first shaft passes through a through hole 231 in the first fixing bracket 23 and cooperates with the first adjusting block 33. The first eccentric wheel body 341 is located between the first fixing bracket 23 and the first support bracket 241. The second shaft passes through the first support bracket 241 and is fixed to the cabinet door panel 2.

[0054] Please continue to refer to Figure 5 , an elastic element 342 is disposed inside the first eccentric wheel body 341. A plurality of second grooves 343 are arranged in a circumferential pattern on one side of the first eccentric wheel 34 facing the first fixing bracket 23. Correspondingly, a plurality of first protrusions 232 are arranged on one side of the first fixing bracket 23 facing the first eccentric wheel 34 and are adapted to cooperate with the plurality of second grooves 343. Combining the first adjusting block 33 with the first shaft and pressing the first shaft, the elastic element 342 inside the first eccentric wheel 34 is compressed, and the cooperation between the first groove 343 and the first protrusion 232 is disengaged. Rotating the first adjusting block 33 adjusts the rotation of the first eccentric wheel 34, thereby driving the bracket structure 20 to move relative to the refrigerator door body 1 in the third direction D3. Here, by pressing the first shaft or the first end of the first eccentric wheel, the cooperation between the first groove 343 and the first protrusion 232 can be disengaged. At this time, the first eccentric wheel can be rotated by using the first adjusting block 33. After the adjustment is completed, releasing the first adjusting block 33 can cause the first groove 343 and the first protrusion 232 to cooperate again by the resilience of the elastic element 342, thereby realizing the locking of the first eccentric wheel.

[0055] In summary, in the present invention, the adjustment box device is buried in the groove of the cabinet door panel. Through the mutual cooperation of the eccentric wheels in the first adjustment structure, the second adjustment structure, and the third adjustment structure, the adjustment of the cabinet door panel in the front-back, left-right, and up-down directions can be realized, which can not only improve the adjustment efficiency, but also improve the installation efficiency and installation accuracy.
