Cushioning shock absorption and noise reduction: The built-in buffer structure relieves the impact force when opening and closing the door, reduces collision noise, and avoids wear caused by hard contact between the door body and the box, improving the quietness of use. Door body posture adjustment: It supports the height of the door body and fine-tune the left and right sides, which can correct the offset of the door body during installation or use, ensure that the door body is flat and aligned, and improve the overall aesthetics and sealing accuracy of the refrigerator. Balanced load-bearing distribution: evenly distribute the weight of the door body to the connection of the box to avoid the deformation of the box caused by excessive local force, ensure the stability of the refrigerator box structure, and extend the service life of the whole machine.
