Problems solved by technology

[0003] The overall die-casting middle hinge is mostly made of zinc-aluminum alloy, and its strength is not high; during the die-casting process, it is easy to cause defects such as pores and cracks inside the middle hinge, which affects the strength and leads to poor stability of the middle hinge product; in order to ensure the strength, it is necessary to increase Thickness, resulting in high investment costs for die-casting equipment and molds, and high cost for medium hinges
[0004] The material of the middle hinge formed by integral sheet metal bending mostly uses 3.5mm thick cold-rolled steel sheet sheet, which is formed by stamping and bending, so the product strength is not high; and because the size is prone to deviation during bending, the product size consistency is poor

Embodiment 1

[0036] like Figure 1 to Figure 3 As shown, this preferred embodiment discloses a middle hinge for a refrigerator, and the middle hinge includes a hinge base 1 and a hinge plate 2 . The hinge plate 2 is provided with a shaft hole 24 , and the middle hinge shaft 3 for connecting the refrigerator door is pierced through the shaft hole 24 . The hinge base 1 is provided with a connecting hole 11, and the hinge plate 2 is provided with a connecting end 21 matching the connecting hole 11, and the connecting end 21 is inserted into the connecting hole 11 and fixed by riveting.

[0037] The hinge base 1 and the hinge plate 2 of the middle hinge are divided into two parts and processed separately, which simplifies the processing technology, and can optionally use high-strength steel as the material, which enhances the strength of the hinge in the refrigerator and meets the use requirements of the refrigerator door.

[0038] The hinge plate 2 is made of a sheet steel plate, and the two...

Embodiment 2

[0046] This preferred embodiment discloses a hinge in a refrigerator, the structure and process of which are basically the same as those of the first preferred embodiment. The middle hinge includes a hinge base and a hinge plate, and the hinge plate is provided with a middle hinge shaft for connecting the refrigerator door. A connecting hole is arranged on the hinge base, and a connecting end matching the connecting hole is arranged on the hinge plate, and the connecting end is inserted into the connecting hole and fixed by riveting.

[0047] The difference lies in: the material of the hinge base and the hinge plate is not limited, and the two can be the same or different, as long as they can meet the strength requirements of the middle hinge; the installation method of the hinge base and the refrigerator shell is not limited , it can be fixed through mounting holes or other fixed connection methods; even if the mounting holes are used for fixing, the number of mounting holes ...

Embodiment 3

[0049] This preferred embodiment discloses a refrigerator. The refrigerator is provided with the middle hinge of the refrigerator as described in the preferred embodiment 1 or 2, and the two ends of the middle hinge shaft are respectively connected to the upper door and the lower door of the refrigerator.

Abstract

The invention discloses a refrigerator middle hinge, a processing method for the refrigerator middle hinge and a refrigerator and belongs to refrigeration equipment accessories and processing methods for the refrigeration equipment accessories. The refrigerator middle hinge is designed to solve the problem that an existing middle hinge is poor in strength. The refrigerator middle hinge comprises a hinge base and a hinge plate, the hinge plate is provided with a middle hinge shaft for being connected with a refrigerator door, the hinge base is provided with a connecting hole, the hinge plate is provided with a connecting end matched with the connecting hole, and the connecting end is inserted in the connecting hole and fixedly pivoted. The refrigerator middle hinge is arranged in the refrigerator, and two ends of the middle hinge shaft are connected with an upper door and a lower door of the refrigerator respectively. According to the refrigerator middle hinge, the processing method for the refrigerator middle hinge and the refrigerator, a process is simple, refrigerator middle hinge processing efficiency is high, the refrigerator middle hinge processing cost is low, and the middle hinge obtained by processing is high in strength, can support a heavy refrigerator door body, cannot be damaged easily in the transport process and is long in service life and suitable for installation of various refrigerator doors.

Description

technical field [0001] The invention relates to a hinge in a refrigerator, a processing method for the hinge in the refrigerator and a refrigerator provided with the hinge in the refrigerator. Background technique [0002] The middle hinge is an important part that supports the refrigerator door. During the transportation and use of the refrigerator, the middle hinge needs to bear a relatively large force. The development trend of refrigerators is large volume, energy saving, and glass doors, which correspondingly lead to an increase in the size, thickness, and weight of the door body of the refrigerator. These three changes eventually lead to heavier and heavier refrigerator doors, so the strength requirements for the middle hinge are also getting higher and higher. Most of the existing middle hinges are formed by integral die-casting or integral sheet metal bending. [0003] The overall die-casting middle hinge is mostly made of zinc-aluminum alloy, and its strength is ...
