Example 2

[0026] The present embodiment provides a method for installing a built-in refrigerator door body and a cabinet door, which is used to position a bracket set 2 on a cabinet door 1, and includes the following steps:

[0027] (1) Hang the ruler 3 with the hanger 21 on the top wall of the cabinet door 1 (as shown in FIG. 2 );

[0028] (2) Place the tooling board 4 vertically on one side of the cabinet door 1, with the clamping edge 41 of the tooling board 4 attached to the side wall of the cabinet door 1 (as shown in FIG. 3 );

[0029] (3) When one side of the hanger 21 is aligned with the hanger positioning opening 42 of the tooling plate 4, the hanger mounting surface 211 of the hanger 21 is fixed to the cabinet door 1 by screws (as shown in FIG. 3 );

[0030] (4) Remove the ruler 3 and the tooling plate 4;

[0031] (5) Move the tooling board 4 downward and keep it vertically placed, with its top end placed at the bottom of one end of the hanger 21. Fix the first fixing bracket 22 to the cabinet door 1 at the fixing bracket positioning opening 43 at the bottom of the tooling board 4 by screws (such as Figure 5 shown);

[0032] (6) Place the tooling board 4 horizontally, with one of the fixing bracket positioning holes 43 on its side located above the first fixing bracket 22, and fix the second fixing bracket 22 on the cabinet door 1 at another fixing bracket positioning hole 43 on its side (as shown in FIG. 6);

[0033] (7) Place the tooling board 4 vertically, with a fixing bracket positioning opening 43 at the top thereof located at the lower part of the second fixing bracket 22, and fix the third fixing bracket 22 to the cabinet door 1 at another fixing bracket positioning opening 43 at the bottom thereof (as shown in FIG. 7);

[0034] (8) Using the fixing frame 22 fixed in the previous step as a reference point, repeat steps (6) and (7) to complete the fixing of the remaining fixing frames 22.

[0035] Among them, the horizontal and vertical placement of the tooling board 4 in steps (6)-(8) is not affected by the sequence, and the next step can be performed with the fixed fixing frame 22 as the reference point.

[0036] After the positioning of the bracket set 2 on the cabinet door is completed, the connection and installation with the corresponding adjustment mechanism set on the door body 5 of the built-in refrigerator can be completed by using the hanging bracket 21 and the fixing bracket 22.

[0037] Specifically, as shown in FIG8 , the built-in refrigerator door body 5 is arranged below the hanger surface 212, and the hanger surface 212 is provided with a long hole 215. The adjustment mechanism group includes an adjusting bolt 6 located at the top of the built-in refrigerator door body 5. As shown in FIG9 , the adjusting bolt 6 includes a bolt body 611, and the length and width of the long hole 215 are greater than the diameter of the bolt body 611. The top surface of the bolt body 611 is hexagonal, and its top passes through the long hole 215 and is sleeved with a nut 612. The lower thread is penetrated in the top frame 51 of the built-in refrigerator door body 5, and a disc body 63 integrally formed with the adjusting bolt 6 is provided between the hanger surface 212 and the top frame 51. The diameter of the disc body 63 is greater than the length of the long hole 215, and the top frame 51 is provided with a circular groove 64 adapted to the disc body 63; referring to FIG10 , the fixing frame 22 includes a fixing frame 22 fixed to the cabinet door 1 A fixing frame mounting surface 221 is formed on the built-in refrigerator door 5, and the middle part of the fixing frame mounting surface 221 protrudes outward to form a cavity 222. A movable plate 223 that can move left and right along the cavity 222 is inserted into the cavity 222. Both sides of the movable plate 223 are bent outward to form adjustment blocks 224 close to the left and right sides of the cabinet door 1, and a limit block 225 close to the middle part of the cabinet door 1. Referring to Figure 11, spaces 52 for accommodating the fixing frame 22 are provided on the left and right sides of the built-in refrigerator door body 5, and locking screws 53 are provided on the side walls of the built-in refrigerator door body 5, and the protruding ends of the locking screws 53 can be tightened on the adjustment blocks 224.

[0038] During assembly, the cabinet door 1 is hung on the built-in refrigerator door body 5, and the top surface of the bolt body 611 is tightened with an inner hexagonal wrench to adjust the installation height of the cabinet door 1; since the length and width of the long hole 313 are greater than the diameter of the bolt body 411, the cabinet door 1 can be moved to adjust the front and back and left and right directions of the cabinet door 1, and then the nut 612 and the locking screw 53 are tightened to complete the installation of the built-in refrigerator door body and the cabinet door. Example 3

[0039] In order to improve the efficiency of assembly and the initial positioning accuracy of the ruler 3, as shown in FIG12, before step (1) of embodiment 2, the hanger surface 212 of the hanger 21 is fixed to the top wall of the cabinet door 1, and the top of the ruler 3 is set against the top of the installation space of the cabinet door 1 ( Fig.12 The position shown is the bottom surface of the upper cabinet door 7 on the cabinet door 1). After the ruler 3 and the bracket 21 are moved downward as a whole, step (1) is performed. In this way, the role of the ruler 3 can be effectively utilized to keep the bracket 21 completely parallel to the top wall of the cabinet door 1, thereby ensuring the installation accuracy. Example 4

[0040] In order to facilitate the positioning of the tooling plate 4 when placed horizontally, see Figure 4 A protrusion 8 for fitting onto the side wall of the cabinet door 1 is provided on the end surface of the tooling plate 4 . Example 5
