Description

Technical Field

[0001] This utility model relates to the field of wine cabinet technology. Background Technology

[0002] Currently, Chinese utility model patent CN201220440070.5 discloses a concealed wine cabinet / refrigerator door limiting mechanism. It includes a cabinet body and a door that seals the cabinet opening. Concealed limiting structures are installed at the upper and lower ends of one side of the cabinet body and the door. Each concealed limiting mechanism includes a hinge plate fixed to the cabinet body, with a transverse support arm extending from the hinge plate. A limiting component is installed on the corresponding cabinet door, and a limiting through groove is formed on the limiting component. The end of the transverse support arm is connected to a pivot. With the rotatable connection to the limiting groove, the horizontal support arm is concealed within the limiting groove when the cabinet door is closed. When the door is opened to its maximum angle, the limiting components fixed to the upper and lower parts of the cabinet door and the hinge plates fixed to the upper and lower parts of the cabinet body interfere with each other. The end face of the limiting groove abuts against the horizontal support arm, preventing the cabinet door from opening further. This achieves the simultaneous upper and lower limiting function of the door. Since the horizontal support arm is concealed within the limiting groove when the cabinet door is closed, it is ingenious, novel, practical, and aesthetically pleasing. The problems are as follows: 1. Because the hinge plates at the top and bottom of the cabinet are exposed, the top surface of the cabinet door is higher than the top surface of the cabinet and the bottom surface 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 hinge axis of the upper hinge plate is vertically upward, and the hinge axis of the lower hinge plate is vertically downward. The cabinet door is entirely supported by the horizontal support arm at the top of the cabinet, while the horizontal support arm at the bottom of the cabinet does not support the door, resulting in poor durability and stability of the cabinet door; 3. The hinge holes at the top and bottom of one side of the cabinet door are exposed, making the cabinet door even more unsightly; 4. When installing the cabinet door, one hinge plate must be fixed first, then the cabinet must be flipped over and the hinges on both hinge plates must be inserted into the hinge holes of the cabinet door before the other hinge plate is fixed to the cabinet, making the installation and removal of the cabinet door inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a wine cabinet with a concealed hinge design. It features a concealed hinge and rotation hole structure, making assembly convenient. Furthermore, the top surface of the door is flush with the top surface of the cabinet, resulting in a very flat and aesthetically pleasing overall appearance. At the same time, the hinge pivots on the two hinges located at the top and bottom support the door, ensuring balanced force distribution and making the door more durable and stable.

[0019] This utility model discloses a wine cabinet with a concealed hinge design. Because a hinge cavity is provided in the door body, the hinge's bearing plate and hinge shaft are embedded in the hinge cavity, and the hinge shaft rotatably engages with the rotating hole. The fixing part of the pad is fitted and fixed into the fixing cavity, and the pad is in contact with the bottom plate of the hinge cavity. When the door is closed, the bearing plate is embedded in the hinge cavity, and the fixing plate is located in the gap between the door body and the cabinet body, thus achieving a concealed hinge structure. Compared with the prior art, this design has the following advantages:

[0020] 1. The bearing plate and hinge shaft are hidden inside the hinge cavity, and the door hinge and hinge hole are not exposed. Furthermore, the top surface of the door is flush with the top surface of the cabinet, making the overall appearance of the wine cabinet or refrigerator flat and beautiful.

[0021] Second, the hinge pivots on the two door hinges at the top and bottom support the weight of the door, making the door body supported by a balanced force, less prone to tilting, enhancing the stability and durability of the door body, and effectively extending the service life of the wine cabinet.

[0022] 3. The hinge axis is set at the corner formed by the bottom of the hinge plate and the right angle side, which can reduce the rotation space of the inner side of the door hinge, making it convenient for the wine cabinet to be installed in a recessed manner.

[0023] Fourth, the assembly or disassembly of the doors is more convenient and faster, improving the production efficiency of the wine cabinet. Attached Figure Description
