Refrigerator door hinge with damping buffering structure

Abstract

The invention relates to the technical field of hinges, and discloses a refrigerator door hinge with a damping buffering structure. The refrigerator door hinge comprises a base used for connecting a refrigerator cabinet body, and a connecting rod used for connecting a refrigerator door, wherein the base is rotatably connected with a cam disc by virtue of a center pin shaft, one end of the connecting rod is provided with a connecting hole used for being connected with the refrigerator door, the other end of the connecting rod is connected with the cam disc by virtue of a first hinge shaft, thebase is provided with a cam jacking and pressing mechanism for controlling the rotating speed of the cam disc, and the cam jacking and pressing mechanism comprises a cam jacking and pressing head applying the pressure onto a cam surface of the cam disc; and the base is also provided with a damper for retarding the closing speed of the refrigerator door, the connecting rod is provided with a connecting rod extension section, and the end part of the connecting rod extension section is in contact with the damper when the refrigerator door rotation angle is smaller than or equal to a set criticalangle. By adopting the refrigerator door hinge with the damping buffering structure, the user experience to open and close the refrigerator door is improved, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a refrigerator door hinge with a damping buffer structure. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. Structurally, the refrigerator includes a refrigerator cabinet body and a refrigerator door, wherein the refrigerator door and the refrigerator cabinet body are rotatably connected to each other by means of rotationally fitted pin shafts. [0003] The rotating connection structure between the refrigerator door and the refrigerator cabinet in the prior art has the following problems: [0004] One is that during the opening process of the refrigerator door, if the user turns the refrigerator door to the desired angle and then lets go, the refrigerator door will often continue to rotate due to the effect...

AI Technical Summary

Problems solved by technology

[0004] One is that during the opening process of the refrigerator door, if the user turns the refrigerator door to the desired angle and then lets go, the refrigerator door will often continue to rotate due to the effect of inertia, making the refrigerator door fully open, resulting in more cold air loss and affecting the performance of the refrigerator. Energy-saving effect; and when the refrigerator door is fully opened due to inertia, it is easy to collide with the refrigerator cabinet, and it will rebound after the collision. On the one hand, it affects the user experience, and on the other hand, the collision point and the pin joint are easily damaged. Reduce product life

[0005] Second, during the closing process of the refrigerator door, it will also continue to rotate due to the effect of inertia after letting go, resulting in an impact between the refrigerator door and the refrigerator cabinet, and the sound is louder. On the one hand, it reduces the distance between the refrigerator door and the refrigerator cabinet. The service life of the sealed magnetic strip, on the other hand, the loud closing sound also affects the quietness of the environment
