Connecting device for electric refrigerator door

Abstract

The invention discloses a connecting device for a refrigerator door. The main features are: the right end of the connecting seat A at the right rear end of the upper surface of the top plate of the refrigerator body is provided with a bearing seat A, the outer diameter of the bearing A in the bearing hole A of the bearing seat A is tightly matched with the bearing hole A, and the bearing A The inner hole of the pin shaft A is closely matched with the journal A of the integral structure at the upper end of the pin shaft A; the right end of the connecting seat B at the right rear end of the partition between the refrigerating room and the freezing room of the refrigerator body is provided with a bearing seat B, and the bearing seat B The outer diameter of the bearing B in the bearing hole B at the upper end is tightly fitted with the bearing hole B, and the inner hole of the bearing B is tightly fitted with the journal B at the lower end of the bearing pin B. The invention can reduce wear and tear. After the refrigerator is used for a long time, the outer end of the refrigerator door will not hang down. When the refrigerator door is closed, it can be sealed and closed naturally, so that the hot air outside will not enter the refrigerator. Excellent refrigeration effect, save electricity, save electricity expenses, and maintain the original beautiful appearance of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a connecting device for a refrigerator door. Background technique [0002] The connection between the refrigerating chamber door on the upper part of the existing refrigerator and the refrigerator is to drill a round hole on the right rear end of the top plate of the refrigerator, and then insert the upper part of the pin shaft that is injection molded with the upper end of the refrigerating chamber door into the refrigerator In the round hole drilled on the top plate, insert the lower part of the pin, which is injection molded with the lower end of the refrigerator door, into the round hole on the bracket at the rear end of the right end face of the partition between the upper refrigerator compartment and the lower freezer compartment of the refrigerator. connected together. Since the interior of the refrigerator door is provided with multi-layer racks, eggs, bottled beve...

AI Technical Summary

Problems solved by technology

Since there are multi-layer shelves inside the refrigerator door, eggs, bottled drinks and food are placed in the shelves in daily life, which increases the weight of the refrigerator door and increases the drooping force of the outer end of the refrigerator door. , when the refrigerator door is opened, the pin shaft at the upper end of the refrigerator door needs to carry a larger downward torque caused by the drooping force, and because the refrigerator door is often opened and closed, the gravity of the refrigerator door and the multi-layer shelf Under the action of gravity and downward torque of the eggs, bottled beverages and food inside, the round hole drilled on the top plate of the refrigerator rubs against the upper part of the pin shaft continuously, gradually wears out and becomes an oval hole. When the door of the refrigerator is opened , the outer end of the refrigerating room door hangs down, causing the refrigerating room door to be unable to be sealed and closed naturally, causing the outside hot air to enter the refrigerating room, which not only affects the refrigerating effect of the refrigerating room, but also wastes electric energy, and increases the electricity bill at the same time, resulting in huge Even if the refrigerator door is lifted up when the refrigerator door is closed, the outer end of the closed refrigerator door still hangs down, which affects the appearance of the refrigerator
