Referring to fig. 1-7, in some embodiments, a door body assembly includes: the door body 100, the boss 200, and the decorative cover 300. Shaft grooves 400 are formed in both end regions of the upper sidewall of the door body 100; the shaft sleeve 200 is detachably arranged in one of the two shaft grooves 400; the decorative cover 300 is detachably disposed in the other of the two shaft grooves 400.

By adopting the door body assembly provided by the embodiment of the disclosure, the shaft grooves 400 are respectively formed in the two end regions of the upper side wall of the door body 100, the shaft sleeve 200 is arranged in one of the two shaft grooves 400, the decorative cover 300 is arranged on the other cover, the shaft sleeve 200 is used for assembling the door body 100 with the box body, and the decorative cover 300 is used for covering the other empty shaft groove 400. The shaft sleeve 200 and the decorative cover 300 are detachably arranged, and when the installation direction of the door body 100 needs to be changed, the shaft sleeve 200 and the decorative cover 300 are detached and the installation position is changed. Due to the arrangement of the decorative cover 300, the empty shaft groove 400 can be covered, so that foreign matters such as external dust can be prevented from entering the empty shaft groove 400 to pollute the empty shaft groove 400, the risk of pollution to the shaft groove 400 is reduced, the appearance of the upper side wall of the door body 100 is kept consistent, and the efficiency of replacing the installation direction of the door body 100 is improved.

Alternatively, the door body 100 is a rectangular plate-like structure. In this way, the door body 100 can be better adapted to the use of the refrigeration appliance, better sealing the refrigeration compartment of the refrigeration appliance.

Specifically, the upper side wall of the door body 100 has a rectangular structure, and two shaft grooves 400 are respectively disposed in the areas where the two short sides of the upper side wall of the door body 100 are located. In this way, since the door body assembly is rotated along one side thereof after installation, the two shaft grooves 400 are respectively provided at the two short side areas of the upper side wall of the door body 100, so that the door body 100 can be rotated along the side corresponding to one of the short sides after replacement installation.

Specifically, both shaft grooves 400 are provided in the middle region of their corresponding short sides. In this way, when the door body 100 is assembled through one of the two shaft grooves 400, the stability of the door body 100 can be improved, and tilting is less likely to occur.
