Embodiment 1

[0019] The door height adjustable hinge of the present invention is used for the middle hinge 21 of the refrigerator. The hinge is processed by sheet metal technology. The supporting surface 13 of the refrigerator door body 23 is substantially at right angles, and the two surfaces are transitional with small rounded corners. The extended end of the supporting surface 13 is stretched out on the fixed surface, and at least one fixing hole 19 is set toward the bottom of the fixing direction, preferably two holes are arranged. 19 fixing holes.

[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 that 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 higher than the height of the support surface Out about 20-40%.

[0021] The extension end includes t...

Embodiment 2

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

[0028] Referring to accompanying drawing 5, this accompanying drawing is the schematic diagram of this embodiment, and in this accompanying drawing, hinge 22 is consistent with embodiment 1 and other places in the description of the present invention, and just omits detailed structural diagram in accompanying drawing .

[0029] In order to improve the strength of the hinge in this embodiment, at least one reinforcing rib is provided on the supporting surface, and the reinforcing rib is composed of a reinforcing rib end portion 16, a reinforcing rib bending portion 17, and a reinforcing rib extending end 18, that is to say, the reinforcing rib The rib extends from the supporting surface to its downward bending portion, and the length from the bent portion 17 of the reinforcing r...

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...
