Description

Three-rope traction suspension lifting device for TV

technical field

The utility model relates to the technical field of household appliances, in particular to a TV three-rope traction suspension lifting device.

Background technique

At present, ultra-thin flat-panel TVs such as LCD TVs are generally placed on one wall of the living room, or hung and fixed on one wall of the living room. For this reason, it is necessary to configure the TV cabinet and other auxiliary furniture for the TV. The space taken up for a TV may not be a big deal in a large house, but it can be troublesome in a small room. One is that the supporting TV cabinets take up too much space, making the living room crowded; the other is that if you use a TV set of more than 50 inches, it will cause people's discomfort due to the small viewing distance.

As the frequency of use of TV sets is gradually decreasing, TV sets are no longer the entertainment center at home. There have also been some TV ceiling mounts that can be lifted and folded automatically on the market. When the TV is not in use, the TV can be stored on the ceiling, so as not to occupy the floor space. And it can be more flexible in the location of the TV set. For example, in some rectangular rooms where the living room and dining room are integrated, the TV set can be hung near the dining room, thereby increasing the viewing distance of the TV set. But the current TV ceiling bracket still has many limitations, for example, the lifting height is limited, and it can only be lowered to a very small height, and it needs to look up when using it. For example, you can only fix the viewing angle, and you cannot turn left and right. Therefore need badly to redesign a kind of TV ceiling bracket to meet people's requirement that life is more and more comfortable.
