The first transverse reinforcing plate 710 may be made of a metal material, so that deformation is small when the screw of the front and rear adjusting screw 630 is pressed against it, improving the reliability of adjustment. In addition, when the screw of the front and rear adjusting screw 630 abuts against the rear side of the cabinet door 200, the screw may be specifically configured to abut against the vertical wrapping 220 of the cabinet door 200, so that the fixing flange 520 of the vertical reinforcement 500 can support the vertical wrapping 220 of the cabinet door 200, and therefore, when the screw of the front and rear adjusting screw 630 abuts against the vertical wrapping 220, the influence on the cabinet door 200 is small, and the reliability of further adjustment is low.

After the cabinet door body 200 and the refrigerator door body 100 are installed in place, in the width direction, the end portion of the second plate section 320 can be opposite to the cabinet door body 200 (vertical edge 220), the middle portion of the second plate section can be opposite to the first transverse reinforcing plate 710, the screw of the front and rear adjusting screw 630 can be screwed into the third threaded hole 322 from the outer side, and the tail end of the screw is abutted against the rear side of the cabinet door body 200 or the first transverse reinforcing plate 710 (depending on the position of the third threaded hole 322), so that the distance between the cabinet door body 200 and the refrigerator door body 100 is adjusted by screwing the front and rear adjusting screw 630 into or out of the third threaded hole 322, and further the cabinet door body 200 and the refrigerator door body 100 keep equal distance in all positions in the front and rear direction.

Referring to fig. 5 to 7, in some specific embodiments, two third threaded holes 322 are formed in the second plate section 320 of each door body guide rail 300, wherein one third threaded hole 322 is opposite to the cabinet door body 200, and the other third threaded hole 322 is opposite to the first transverse reinforcing plate 710.

That is, each set of guide rail mechanism may be configured with two front and rear adjusting screws 630, wherein a screw of one front and rear adjusting screw 630 may be pressed against the rear side (the vertical binding 220, as shown in fig. 5) of the cabinet door body 200, and the other front and rear adjusting screw 630 is pressed against the first transverse reinforcing plate 710 (as shown in fig. 6).

Referring to fig. 5 to 7, the connection plate section 430 is formed with

notches

434 and 436 at the positions of the two third screw holes 322 to avoid an operating space of the front-rear adjustment screws 630 engaged with the two third screw holes 322. Since the rear surface of the second plate section 320 is opposite to the connecting plate section 430, and the front-rear adjusting screw 630 passes through the rear surface of the second plate section 320 to the front surface, and finally abuts against the rear side of the cabinet door 200 or the first transverse reinforcing plate 710, the connecting plate section 430 occupies the operating space of the front-rear adjusting screw 630, and therefore, the

notches

434 and 436 formed in the connecting plate section 430 can release the operating space of the front-rear adjusting screw 630, which is convenient for operation.

Referring to fig. 6 and 8, in addition, the gap 436 of the connecting plate segment 430 at the third threaded hole 322 opposite to the first transverse reinforcing plate 710 is larger in size, and the gap 436 can release the space of the guide 400 facing the door body guide rail 300 in addition to the operation space of the front and rear adjusting screw 630, so that when the cabinet door body 200 is assembled, the middle plate segment 420 of the guide 400 can be firstly lapped on the third plate segment 330, and then the cabinet door body 200 is pushed to move integrally, thereby facilitating the assembly.

Referring to fig. 2, further, the door connecting assembly may further include a plurality of pre-tightening arch plates 720, the pre-tightening arch plates 720 are sequentially arranged at the rear side of the cabinet door 200 along the height direction, each pre-tightening arch plate 720 extends along the transverse direction, both ends of each pre-tightening arch plate 720 are respectively fixed to the connecting flanges 510 of the two vertical reinforcements 500, and the middle portion of each pre-tightening arch plate 720 is arched towards the refrigerator door 100 so as to push out a front-back adjusting gap between the cabinet door 200 and the refrigerator door 100.

Because the center of the pre-tightening arch 720 protrudes from the cabinet door 200, when the refrigerator door 100 and the cabinet door 200 are installed in place, the cabinet door 200 and the refrigerator door 100 can be pushed out of the front-back adjusting gap, so that the cabinet door 200 can be adjusted front-back.

In addition, when a gap exists between the refrigerator door body 100 and the cabinet door body 200, the pre-tightening arch plate 720 can also be abutted against the refrigerator door body 100, so that the middle parts of the cabinet door body 200 and the refrigerator door body 100 have certain pre-tightening force, and the middle part of the cabinet door body 200 can be prevented from collapsing.

In addition, after the cabinet door 200 and the refrigerator door 100 are installed in place, the pre-tightening arch plate 720 is compressed, and two ends of the pre-tightening arch plate are fixed on the connecting flanges 510 of the vertical reinforcements 500, so that the pre-tightening arch plate 720 can apply outward acting force to the two vertical reinforcements 500, the first transverse reinforcing plate 710 is connected between the two vertical reinforcements 500, the first transverse reinforcing plate 710 can pull the two vertical reinforcements 500 towards the middle, and therefore the acting force generated by the pre-tightening arch plate 720 can be offset by the first transverse reinforcing plate 710, so that the connection between the cabinet door 200 and the refrigerator door 100 is more stable and is not easy to deform.

Referring to fig. 2, 4-6, in some embodiments, the door body coupling assembly may further include an insulation laminate 730 and a plurality of support layers (not shown), the insulation laminate 730 being disposed in the recessed area 210 between the two vertical stiffeners 500, each support layer being disposed between the pre-tensioned arch 720 and the insulation laminate 730.
