The elastic buckle cover main body 131 and the shell main body 111 are both prior arts, which will not be described herein.
[0029] The reverse buckle 132 cooperates with the reverse buckle mounting hole 113. When the middle beam shell 11 and the elastic buckle cover 13 are assembled together, the reverse buckle 132 corresponds to the reverse buckle mounting hole 113, so as to fix the middle beam shell 11 and the elastic buckle cover 13. Moreover, the elastic buckle cover 13 is made of plastic material, that is, the elastic buckle cover 13 can elastically deform under stress. When the middle beam shell 11 and the elastic buckle cover 13 are separated, the user applies force to the elastic buckle cover 13 to make the elastic buckle cover 13 deform, so that the reverse buckle 132 and the reverse buckle mounting hole 113 are separated, thereby the middle beam shell 11 and the elastic buckle cover 13 are completely separated.
[0030] The limiting protrusions 133 are arranged in the elastic buckle cover body 131, and the limiting protrusions 133, the reverse buckles 132 and the elastic buckle cover body 131 are integrally formed, so that the structure of the limiting protrusions 133, the reverse buckles 132 and the elastic buckle cover body 131 is stable, and the limiting protrusions 133 are used for limiting the position of the heat preservation member 122, when the heat preservation member 122 is installed in the middle beam shell 11, each limiting protrusion 133 is inserted into one installation slot 1222, so that the position of the heat preservation member 122 in the middle beam shell 11 is stable.
[0031] Compared with the prior art, the split type heat preservation middle beam for the refrigerator is fixed by the middle beam shell 11 and the elastic buckle cover 13. The middle beam shell 11 is provided with reverse buckle installation holes 113 at the edges of the shell body 111, and the elastic buckle cover 13 is provided with reverse buckles 132 at the edges of the elastic buckle cover body 131. When the middle beam shell 11 and the elastic buckle cover 13 are assembled together, the reverse buckles 132 and the reverse buckle installation holes 113 correspond to each other, the middle beam shell 11 and the elastic buckle cover 13 are fixed, the connection between the middle beam shell 11 and the elastic buckle cover 13 is realized, and the elastic buckle cover 13 can be elastically deformed by the user applying pressure to the elastic buckle cover 13, so that the middle beam shell 11 and the elastic buckle cover 13 are separated. In addition, the heat preservation unit 12 comprises a heating device 121 accommodated in the shell body 111 and a heat preservation member 122 arranged on one side of the heating device 121. The heating device 121 and the heat preservation member 122 can be independently separated for maintenance.
