Freezer Balanced Hinge Structure and Top Opening Freezer

Abstract

The invention proposes a freezer balance hinge structure and a top-opening freezer. The hinge head of the freezer balance hinge structure is hinged to the hinge seat through the hinge shaft, the hinge joint is hinged with a movable shaft, and the bottom of the hinge seat is assembled and connected with a support seat. A friction seat made of elastic material is connected. The upper part of the friction seat is a boss with a thin upper part and a thicker bottom. The middle position of the friction seat is provided with an axially penetrating friction groove. The two ends of the spring are respectively assembled and connected with the upper spring seat and the lower spring The middle position of the spring lower seat is provided with a bayonet that can be slidably connected with the boss. The spring upper seat is assembled and connected with a spring support plate. One end of the spring support plate is movably inserted into the friction groove, and the other end of the spring support plate passes through the support pad Active Link Active Axes. The beneficial effects of the present invention are: to realize the balance and control of the door body at any point within a larger opening angle range; to reduce the impact of the door body on the cabinet body when the door body is closed and to avoid the door body from rapidly bouncing upward when the door body is opened .

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator balance hinge structure and a top-opening refrigerator. Background technique [0002] The door body of the top-opening refrigerator is hinged to the cabinet body of the refrigerator through hinges. At present, most of the top-opening refrigerators on the market have a poor man-machine relationship when opening and closing the door. Specifically: when the door is opened, the door is affected The elastic force of the hinge spring and the gravity of the door body itself, but the door body cannot remain static within a certain opening range, and the angle range of the controllable state is very small, and it is difficult for the user to accurately find the controlled angle range, so that the door body Balance and keep still; in addition, when closing the door, in order to reduce the impact of the door falling rapidly due to its own gravity on the cabinet, it is n...

[0002] The door body of the top-opening refrigerator is hinged with the cabinet body of the refrigerator through hinges. At present, most of the top-opening refrigerators on the market have a poor man-machine relationship when opening and closing the door. Specifically: when the door is opened, the door is affected. The elastic force of the hinge spring and the gravity of the door body itself, but the door body cannot remain static within a certain opening range, and the angle range of the controllable state is very small, and it is difficult for the user to accurately find the controlled angle range, making the door body Balance and keep still; in addition, when closing the door, in order to reduce the impact of the door falling rapidly due to its own gravity on the cabinet, it is necessary to increase the spring force to balance the gravity of the door itself, but when opening the refrigerator door When the door body is closed, due to the elastic force of the spring, the door body will bounce up rapidly, which may easily cause the user to be frightened or even injured.
