Description

Technical Field

[0001] The invention relates to the technical field of wine cabinets or refrigeration cabinets. Background Art

[0002] At present, the Chinese utility model patent with the patent number of CN201220440070.5 of the prior art discloses a hidden wine cabinet / refrigerator door body limiting mechanism, which includes a cabinet body and a cabinet door sealing the cabinet body opening, and the upper and lower ends of one side of the cabinet body and the cabinet door are respectively installed with hidden limiting structures, and each hidden limiting mechanism includes a hinge plate fixed on the cabinet body, and a horizontal support arm extends from the hinge plate, and a limiting member is installed on the corresponding cabinet door, and a limiting through groove is opened on the limiting member, and the end of the horizontal support arm is connected by a rotating shaft. It is rotatably connected to the limit slot, and when the cabinet door is in the closed state, the horizontal support arm is concealed in the limit slot; when opening and closing the door, when the cabinet door is opened to the maximum angle, the limit pieces fixed on the upper and lower parts of the cabinet door and the upper and lower hinge plates fixed on the cabinet body interfere with each other, and the end faces of the limit slot abut against the horizontal support arm, so that the cabinet door cannot be opened at a wider angle, thereby realizing the simultaneous upper and lower limiting effect of the door body. Since the horizontal support arm is concealed in the limit slot when the cabinet door is in the closed state, it is ingenious, novel, practical and beautiful. The existing problems are: 1. Since the hinge plate on the upper part of the cabinet is exposed and installed on the top of the cabinet and the hinge plate on the lower part of the cabinet is exposed and installed on the bottom of the cabinet, the top surface of the cabinet door is higher than the top surface of the cabinet and the bottom surface of the cabinet door is lower than the bottom surface of the cabinet, resulting in an uneven and unsightly overall appearance of the wine cabinet or refrigerator; 2. The axis of the hinge plate located on the upper part of the cabinet is vertically upward, and the axis of the hinge plate located on the lower part of the cabinet is vertically downward. The cabinet doors are all supported by the horizontal support arms on the upper part of the cabinet, and the horizontal support arms on the lower part of the cabinet are not used to bear the cabinet doors, resulting in poor durability and stability of the cabinet doors; 3. The shaft holes of the upper and lower ends of one side of the cabinet door are exposed, making the cabinet door look even more unsightly; 4. When installing the cabinet door, you must first fix one hinge plate, then turn over the cabinet and insert all the shafts on the two hinge plates into the axis holes of the cabinet door, and then fix the other hinge plate on the cabinet, resulting in inconvenient installation and removal of the cabinet door.
