Refrigerator door closing device with free suspension function

Abstract

The invention provides a refrigerator door closing device with a free suspension function. The device comprises a hinge component articulated with a refrigerator cabinet body and a refrigerator door body, wherein the hinge component comprises an articulating shaft fixed at the upper end of the refrigerator cabinet body, and a hinge seat fixed at the upper end of the refrigerator door body; a positioning end of the hinge seat is connected with the articulating shaft in a sleeving manner; a swinging end of the hinge seat rotates by taking the articulating shaft as a fixed point; the hinge seat is provided with a cam, a connecting wheel and an elastic component; the articulating shaft is fixedly sleeved with the cam; positioning grooves and arc surfaces are formed and arranged at the outer edge of the cam; the elastic component acts on the connecting wheel in an elastic buffer manner to allow the connecting wheel to be connected with the positioning grooves and the arc surfaces in a sliding manner with the rotation of the hinge seat; the refrigerator door body can be automatically closed; a closing effect is good; the abrasion is reduced under a heavy load condition; the structural stability and reliability are improved; at the same time, the refrigerator door body can be suspended when the refrigerator door body is opened by a certain angle; and the device is high in use flexibility and applicability.

Description

technical field [0001] The invention relates to the field of refrigerator hinges, in particular to a refrigerator door closing device with any hovering function. Background technique [0002] The refrigerator hinge is currently the most commonly used connecting piece for the rotation and opening of the refrigerator door. In order to achieve a good closing performance between the refrigerator door and the refrigerator cabinet after opening or closing, a door closing device is added to the hinge to close the door. The device has an interference fit with the approximately mountain-shaped structure on the side of the hinge through the approximately mountain-shaped rear wing on the side of the front, and at the same time, its internal mechanism uses shrapnel to achieve the effect of closing the door. In this way, when the refrigerator door is closed, it can be guaranteed that the refrigerator door will not be bounced open, and when it is opened again, because the card slot mainly...

AI Technical Summary

Problems solved by technology

[0004] 1. It cannot be closed automatically, and external force is needed to achieve the closing effect;

[0005] 2. In the long-term opening and closing state of the refrigerator door, due to the heavy load, it is easy to cause friction and collision at the contact position of the door closing device, and the tail is worn, resulting in the loss of the closing effect of the door closing device;

[0006] 3. Due to the assembly of many transmission parts, after the refrigerator door is closed, there is a large gap in the parts inside the hinge, which increases the assembly volume and easily leads to the accumulation of water vapor and dirt

[0007] 4. The door closing device only has the function of rotating and closing or opening, resulting in the limitation of the use state of the refrigerator door, that is, it can only be fully opened or completely closed, and it is difficult to stop the refrigerator door arbitrarily according to the actual application, which affects the use effect
