Description

Technical Field

[0001] The utility model relates to the field of cabinet door panel installation, in particular to an interference-free hidden hinge structure and a special hinge fixing block and furniture using the same. Background Art

[0002] Taking the mirror cabinet as an example, for longer cabinets, there are two methods: the first is double-door, and the second is multiple-door.

[0003] If the doors are double-opened, the cabinet needs to bear a greater force, and the hinged structure is prone to damage over time. In addition, double doors construct two spaces, and for many families, multiple groups of spaces are required, for example, a family has a special space for girls, a special bathing space cabinet for children, etc.

[0004] For cabinets with multiple doors, it is currently difficult to take into account both "cabinet surface flatness and no gaps" and "cabinet doors no interference"; because the middle door needs to be rotated open, sufficient space needs to be left between the side doors.

[0005] On August 22, 2024, a search was conducted in the Chinese Patent Publication Database with "pin and hinge and interference and cabinet" as abstract keywords, and the option to allow synonym expansion was checked. Five documents were found, namely: CN203588875U-Door closing interlocking mechanism for inflatable cabinet; CN108577393B-Portable marketing counter; CN210957336U-A high-protection door for high-altitude distribution cabinets; CN221468067U-Flip-type 1U chassis wiring frame for control console; CN108577393A-Portable marketing counter.

[0006] The applicant applied for CN220267459U - a hinge for a mirror cabinet door. The case designed an L-shaped hinge structure, which is complex to manufacture and cannot completely avoid interference from the edges of the side doors and the middle door. At the same time, the pin of this design is also located on the cabinet body, which makes the processing of the middle plate more difficult.

[0007] On August 22, 2024, an abstract search for "pin and hinge and interference and cabinet" was conducted on China National Knowledge Infrastructure, and no relevant literature was found.
