Fig. 8 is a schematic structural view of the guide shoe 4 of fig. 7. Fig. 9 is a schematic view of the structure of fig. 8 from another perspective.

Referring to fig. 2 to 9, the guide seat 4 is disposed on the top of the refrigerating compartment 11, i.e. fixed on the top wall of the cabinet 1. The guide seat 4 is opposite to the turnover beam 3, and when the door body 2 and the turnover beam 3 are closed, the guide seat 4 is just positioned at the top of the turnover beam 3.
