Design principle:

The present invention transforms the production and connection structure of the traditional TV back shell, and fixes the front shell 1 and the rear shell 2 by combining the buckle structure and the male and female buckle structure, which solves the problems of light weight and screwless appearance .

(1) Lightweight:

Considering that a flat-panel TV case has 20 screws, one screw is about 2g, 20 screws is about 40g, and a 50-inch flat-panel TV is about 20kg, which reduces its weight by 0.2%. Another important step has been taken on the road of quantification.

(2) The appearance is screwless:

Metal screws are used for fixing. After a long time of use, problems such as screw rust and aging will have a great impact on the appearance of the flat-panel TV. At the same time, when installing and removing screws, if there are missing screws, it may also make it There is a little risk in fixing, and at the same time, consumers will have the idea of poor quality; the flat-panel TV casing does not use screws to fix, not only the appearance is more beautiful than before, it is more concise and generous, and it can avoid missing screws. At the same time, it can also give consumers a sense of mystery about how to fix it, and then win more attention from consumers.

As shown in Figure 2, considering the reliability of assembly, 11 female buckle structures are installed on the front shell 1, 3 female buckle structures are arranged on the left and right sides, and 5 female buckle structures are arranged in the middle. The arrangement method effectively controls the connection at each place, ensuring that there will be no gaps after the front and rear shells are assembled.

After testing and verification, after the male buckle structure and the female buckle structure are fastened, the single pull-out force can reach 30N. For example, after 11 male and female buckles are installed at the same time, the pull-out force of the assembly is not only the sum of 11 30N, but also the pull-out force. The pull-off performance can be improved by 50% on the basis of the original 330N. Such a large pull-off force far exceeds the standard requirements.

It is connected in the form of a buckle structure and a male and female buckle structure. When installing the machine back shell, there is no need to unscrew the screws one by one. After carefully removing the machine back shell, the newly invented structure can completely replace the screws. When installing, you only need to buckle and press, and you can easily complete the assembly of the case in two steps. On average, one back case 2 can save 1 minute of man-hours, which saves a lot of time and labor costs, and there are more products in the market. Added a competitiveness.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention.
