Description

Adjustable Hinges and Refrigerator

technical field

The invention relates to the field of household appliances, in particular to an adjustable hinge device and a refrigerator.

Background technique

Usually, the refrigerator door body is pivotally installed on the box body, and during the installation process, the lateral position deviation of the hinge shaft is prone to occur, which leads to the problem of the door body being out of alignment.

In order to solve the above problems, it is necessary to set the position of the hinge shaft to be adjustable. Technicians have carried out research, such as setting the hole on the hinge body for fixing the hinge shaft to a large round hole or an oblong hole, so as to provide a margin for the position adjustment of the hinge shaft, but this scheme not only affects the appearance, but also the adjustment of the hinge shaft. It is completely dependent on human control, and it is impossible to judge how much adjustment is appropriate, making the adjustment very inconvenient.

In addition, there is also a screw nut adjustment structure. For example, the Chinese patent application published on June 13, 2017 and the publication number is CN106837034A discloses a hinge in a refrigerator door and a refrigerator having the same. The hinge includes a hinge body, a hinge support plate, a fixed hinge The hinge shaft is arranged on the hinge support plate. The hinge body is provided with threaded holes, and the hinge support plate is connected with bolts. The distance between the hinge support plate and the hinge body is adjusted by rotating the bolts, so as to adjust the distance between the hinge shaft and the hinge body. The distance between the front and rear of the door body can be adjusted. The hinge adjustment structure provided by this application not only needs a screw nut adjustment structure, but also needs to set a guide structure between the hinge support plate and the hinge body. Therefore, the entire adjustment structure is very complex and expensive. , and the lead screw nut will be exposed, affecting the appearance of the refrigerator. Furthermore, the adjustment structure of the lead screw nut still needs to be completely controlled by humans, and it is impossible to judge how much to adjust and how much to adjust, which makes the adjustment very inconvenient.

Specifically, the fixing member 92 applies the force F3 to the stopper portion 94 , and the direction in which the force F3 is applied to the stopper portion 94 is parallel to the axial direction of the hinge shaft 88 . Therefore, the movement of the hinge shaft 88 relative to the hinge body 90 in the axial direction of the hinge shaft 88 is restricted.

Further, a limit groove 96 is provided on the hinge shaft 88 adjacent to the stop portion 94 , the fixing member 92 is set in a U shape, and the fixing member 92 includes a limit piece 98 matched with the limit groove 96 and arranged opposite to the limit piece 98 . The anti-separation piece 100 and the connecting piece 102 connecting the limit piece 98 and the anti-separation piece 100, the stopper 94 and the hinge body 90 are located between the limit piece 98 and the anti-separation piece 100, and the limit piece 98 and the stopper portion 94 abuts. Thus, the hinge shaft 88 is pressed against the hinge body 90 . Specifically, the limiting piece 98 is provided with an opening 104 located at the limiting groove 96 and matched with the hinge shaft 88 , and the anti-disconnection piece 100 is provided with a fitting hole 106 matched with the hinge shaft 88 . 106 is a long hole.

When adjusting the hinge shaft 88 , the U-shaped fixing member 92 is rotated first, so that the limiting piece 98 is disengaged from the limiting groove 96 , and then the hinge shaft 88 is lifted up. Disengage the positioning ribs on the hinge shaft 88 from the positioning grooves on the hinge body 90, then rotate the hinge shaft 88 to a certain appropriate angle, drop the positioning ribs of the hinge shaft 88 into the corresponding positioning grooves, and finally rotate the U-shaped The fixing piece 92 makes the limiting piece 98 fit with the limiting groove 96 in place, thereby fixing the hinge shaft 88 to the hinge body 90 again. In addition, during the entire adjustment process of the hinge shaft 88 , the U-shaped fixing member 92 is always clamped on both sides of the support portion 107 and is not easy to fall off.

Further, the thickness of the first positioning rib (not shown) and the thickness of the second positioning rib 110 in the axial direction of the hinge shaft 88 are the same. The distance between the anti-separation sheet 100 and the hinge body 90 is greater than the thickness of the first positioning rib (not shown) and the second positioning rib 110 in the axial direction of the hinge shaft 88 . It is set so that when the hinge shaft 88 is lifted up until the first positioning rib, the second positioning rib 110 and the first positioning groove 112 or the second positioning groove 114 are separated, the hinge shaft 88 is not in the axial direction of the hinge shaft 88 either. The disengagement prevention sheet 100 makes the structure of the adjustable hinge device more reliable and convenient to adjust.
