Embodiment Construction

[0018] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The invention provides a refrigerator, see figure 1 and figure 2 , In one embodiment, the refrigerator includes a box body 200 with an open top surface and a door body 300 pivotably arranged on the box body 200 to open or close the top surface of the box body 200 . In this embodiment, the rear side of the door body 300 is connected to the rear side of the box body 200 through a hinge, the door body 300 is located above the box body 200 , and the box body 200 is opened or closed by turning up and down around its rear side rotation axis. It should be understood that the refrigerator also includes other necessary but prior art components, such as compressors, refrigeration pipelines, control panels, etc., which will not be repeated here. In addition, the refrigerator also includes a refrigerator door support de...

Abstract

The invention discloses a refrigerator door support device. The refrigerator door support device comprises a sleeve, a first piston rod, a second piston rod and a reset spring, wherein through-holes matching with the first piston rod and the second piston rod are respectively formed at two opposite ends of the sleeve; one ends of the first piston rod and the second piston rod are respectively placed into the sleeve and form slide matching with the sleeve, and meanwhile, the other ends of the first piston rod and the second piston rod stretch out of two opposite ends of the sleeve; the reset spring is arranged in the sleeve and located between the first piston rod and the second piston rod. On one hand, the refrigerator door support device plays a role in buffering the closing process of a door body, thus damage of a sealing strip caused by direct collision of the door body and the box body can be avoided and potential safety hazard of hurting hands is eliminated; on the other hand, the refrigerator door support device has a slow supporting function to the open process of the door body, thus serious vibration caused by quick bouncing of the door body can be avoided and manpower of opening the door body can be saved.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to a refrigerator door supporting device and a refrigerator. Background technique [0002] In the prior art, a common refrigerator door hinge is composed of a shaft, a hinge body, a pin shaft, and a spring. The spring is sheathed on the pin shaft. When the door is opened, the spring is compressed, and the restoring force of the spring is used to support the door body. In order to support the door body, a spring with a large stiffness coefficient is generally selected. When the opening angle of the door body reaches a certain value, the door body can automatically bounce under the action of the restoring force of the spring; and when the closing angle of the door body reaches a certain value When the value is set, the door body can automatically close under the action of its own gravity. However, the existing door hinges have the following problems in use: in the ...
