Embodiment 1

[0059] A refrigerator hinge device such as figure 1 As shown, it includes a hinge support 1 , a shaft sleeve 2 , a snap ring 3 , a hinge shaft 4 , a door bracket 5 and a retaining ring 6 .

[0060] Among them, such as figure 2 As shown, the hinge support 1 is provided with a through hole 11 and a hinge support through hole 12 . The shaft sleeve 2 is sleeved on the hinge support 1 through the through hole 11 , and the shaft sleeve 2 can rotate in the through hole 11 .

[0061] and, if figure 1 , 3As shown, the outer surface of one end of the sleeve 2 outside the through hole 11 extends outward to form a flange 21 , the lower end of the sleeve 2 is the protruding end, and the protruding end is located outside the through hole 11 . The lower side of the flange 21 abuts against the upper side of the hinge support 1 , so that the sleeve 2 is unidirectionally fixed on the upper side of the hinge support 1 .

[0062] The snap ring 3 is clamped on the protruding end of the lowe...

Embodiment 2

[0077] The structure of the hinge device for refrigerator in embodiment 2 is basically the same as embodiment 1, the difference is as Figure 10 Shown:

[0078] The hinge device does not include a clasp 3 , and the protruding end of the shaft sleeve 2 is only clamped with a retaining ring 6 . Moreover, the outer surface of the flange 21 is formed with an adjusting part for adjusting the rotation of the sleeve 2, that is, the outer surface of the flange 21 is designed as a polygon for easy adjustment, or the outer surface of the flange 21 is provided with knurling for easy adjustment.

Embodiment 3

[0080] The structure of the hinge device for refrigerator in embodiment 3 is basically the same as embodiment 1, the difference is that the installation position of the snap ring is different, such as Figure 11 Shown:

[0081] The snap ring 3 is clamped on the outer surface of the upper end of the shaft sleeve 2 , and the snap ring 3 is located between the flange 21 and the hinge support 1 . The snap ring 3 is used to adjust the rotation of the shaft sleeve 2, and the outer surface of the snap ring 3 is designed as a polygon for easy adjustment, or the outer surface of the flange 21 is provided with knurling for easy adjustment.

Abstract

The invention discloses a hinge device for a refrigerator. The hinge device comprises a hinge support, a hinge shaft and an adjustment assembly, wherein the hinge support is detachably connected to a refrigerator body of the refrigerator; the hinge shaft comprises a supporting plate for supporting a refrigerator door body and an upper extruded part and a lower extruded part which are respectively positioned on the upper side and the lower side of the supporting plate; the adjustment assembly penetrates through a penetrating hole in the hinge support; the upper end part and the lower end part of the adjustment assembly are limited to prevent the adjustment assembly from falling off from the penetrating hole; the lower extruded part is connected to the adjustment assembly; when the adjustment assembly rotates, the hinge shaft moves up and down in the axial direction but does not rotate. The hinge device is compact in structure, small in occupation space and convenient to adjust; furthermore, by long-time use, the refrigerator door cannot move downwards.

Description

technical field [0001] The invention relates to a hinge device for a refrigerator. Background technique [0002] For existing refrigerator doors, due to processing and assembly errors, sometimes the refrigerator door cannot be aligned with the box body. Moreover, even if the refrigerator door is aligned with the cabinet during assembly, the door is likely to move down after a long period of use, which will directly affect the airtightness between the refrigerator door and the refrigerator cabinet, and even This causes the cold air in the box to leak, seriously affecting the refrigeration and freezing effects of the refrigerator. [0003] In the prior art, in order to adjust the height of the refrigerator door, the lower end surface of the refrigerator door is usually provided with a hinge device, and the height of the refrigerator door can be adjusted by rotating the hinge shaft in the hinge device. However, the length of the hinge shaft in the existing hinge device is rel...
