Example Embodiment

[0018] Example 1

[0019] The height-adjustable door hinge of the present invention is a middle hinge 21 used in a refrigerator. The hinge is processed by a sheet metal process. The fixing surface of the hinge 21 is used to be fixed to the refrigerator box 24 and due to the support The support surface 13 of the refrigerator door body 23 is basically at a right angle, and the two surfaces are small rounded arc transitions. At the extension end of the support surface 13 extending from the fixing surface, at least one fixing hole 19 is provided toward the lower part of the fixing direction, preferably two A fixed hole 19.

[0020] There is still a bend at the extension end. In the up and down direction of the fixed surface, the height of the extension end is higher than the height of the non-extension end. In other words, the height of the extension end is higher than the support surface. From the perspective of the entire hinge, the height of the extension end is ...

Example Embodiment

[0026] Example 2

[0027] The rest of this embodiment is the same as Embodiment 1, except that this embodiment more specifically relates to the reinforcing structure of the middle hinge of the present invention.

[0028] Refer to Figure 5, which is a schematic diagram of this embodiment. In this figure, the hinge 22 is consistent with that in Embodiment 1 and other places in the specification of the present invention, except that the detailed structure diagram is omitted in the figure. .

[0029] In this embodiment, in order to improve the strength of the hinge, at least one stiffener is provided on the supporting surface. The stiffener is composed of a stiffener end 16, a stiffener bent portion 17, and a stiffener extension end 18. The rib forms a bent portion extending from the supporting surface to its downward direction, and the length from the bent portion 17 of the rib to the extending end 18 of the rib is about 30-60% of the length of the supporting surfa...

Abstract

The invention relates to a high-strength hinge with adjustable door height for refrigerator, comprising hinge 21, hinge 22, adjusting bolt 27 for door height and fixing bolt 26. In requirement, by adjusting the adjusting bolt 27 for door height the hinge 22 can be adjusted up or down so that the adjusting effect for refrigerator door height can be realized. For improving strength of the hinge 22, an extending end is set on the hinge 22. Fold bending is set on the extending end while at least a stiffener is set on the support part and the bending part so as to improve strength of the hinge greatly. The merit of invention is that because the hinge 21 is formed by sheet metal bending while the structure provided in the invention is collocated it is provided with big strength, simple processing, high productive efficiency and small space cubage compared with die casting or other methods in prior technology.

Description

technical field [0001] The invention relates to a high-strength refrigerator hinge with adjustable door body height. Specifically, the invention relates to a hinge used for the lower end of the door body and capable of adjusting the height of the door body so as to adjust the height of the door At the same time, by adopting the structure and sheet metal processing method proposed by the present invention, the strength of the hinge is even higher. Background technique [0002] CN93231533 discloses a novel door stopper, which includes a hinge seat and upper and lower self-locking blocks, which are respectively installed on the cabinet of the refrigerator, the upper door body and the lower door body. The upper and lower self-locking stops can act on the hinge seat at the same time, and can also act on the hinge seat separately. The use of the door stop device does not affect the function of changing the opening direction of the original refrigerator, and the structure is simpl...
