Embodiment 1

[0033] In Embodiment 1, the above-mentioned living hinge supporting type refrigerator door structure is taken as an example of a side-by-side refrigerator. This structure is realized by adding a first sliding positioning block 3 to the lower decorative strip 2 of the box door and adding a correcting hinge assembly 4 to the door opening side end of the box body 1.

[0034] The first sliding positioning block 3 is fixed on the lower trim 2. The inner upper end surface of the first sliding positioning block 3 is an arc surface, the inner upper end surface of the rear trapezoidal groove portion 32 is a smooth arc surface, and the inner upper surface of the front semicircular groove portion 33 The end surface is a semicircular surface, which is a flat surface. The diameter of the front semicircular groove 33 is slightly larger than the diameter of the correction post 43. The height value of the correction post 43 is 3.5 mm to 5 mm lower than the height value of the front semicircular...

Embodiment 2

[0036] In Embodiment 2, if the door body has been tilted due to an overweight door body, when the door is closed, the upper end surface of the correcting post 43 first contacts the inner upper end surface of the rear trapezoidal groove 32. In the process of closing the door, since the correcting hinge assembly 4 is fixed, the inner upper end surface of the rear trapezoidal groove portion 32 is an upward arc surface, and the door body will be lifted along the inner upper end surface of the rear trapezoidal groove portion 32 for correction. At the end of the door closing process, the upper end of the correcting post 43 is combined with the front semicircular groove 33, and the correcting of the door by the correcting hinge assembly 4 is completed without tilting the door. The first sliding positioning block 3 uses wear-resistant materials and has a smooth surface. Lubricating oil can be applied to the surface to ensure its smoothness before leaving the factory.

Abstract

The invention discloses a living hinge support type refrigerator door structure comprising a refrigerator body and a refrigerator door. The refrigerator door comprises a door body, the door body is rotatably connected with the refrigerator body through a first hinge, the lower end of the door body is connected with a lower trim strip, a first sliding positioning block is arranged on the lower endsurface of the door opening end of the lower trim strip, a hinge correcting assembly is arranged on the front end surface of the door opening end of the refrigerator body, and the lower trim strip isslidably connected to the hinge correcting assembly through the first sliding positioning block. A first wedge-shaped groove is formed in the rear end surface of the first sliding positioning block; and the hinge correcting assembly comprises a correcting fixing block, a correcting front supporting block and a correcting stand column, the correcting fixing block is fixedly connected with the refrigerator body, the correcting front supporting block is fixedly connected to the front end of the correcting fixing block, the correcting stand column is connected to the upper end of the correcting front supporting block, the correcting stand column is clamped into the first wedge-shaped groove and is connected with the first sliding positioning block. In the refrigerator door structure, through cooperation of the first sliding positioning block and the hinge correcting assembly, the problem of tilting of the door body is solved, and the structure is simple and novel.

Description

Technical field [0001] The invention relates to the field of refrigerators, in particular to a living hinge supporting type refrigerator door structure. Background technique [0002] Refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a kind of civilian product that keeps food or other items in a constant low temperature and cold state. There are cabinets or boxes for freezing compressors, ice machines, and storage boxes with refrigeration devices. Nowadays, refrigerators have become indispensable household appliances in the lives of the general public. In the production of refrigerators, the excessively heavy doors are restrained only by the force of a single-sided hinge, which is easy to cause the phenomenon of unevenness of the door. It is more serious in an overweight refrigerator. At present, there is a way to control the tilt of the door body by adding a horizontal tray or support frame under the refrigerator door, and t...
