When installing the panel, it can make the installation more accurate and easy. There is also prior art 2 (Chinese patent application number 202220995604.4, application date 2022-04-24) A mounting structure for the back shell of a TV, comprising: a shell assembly and a mounting assembly, the shell assembly comprising a back shell body, a convex surface extending outward is provided on the side wall of the back shell body, four notches are evenly distributed on the side wall of the convex surface, and a plurality of heat dissipation openings connected inside and outside are evenly distributed on the convex side wall inside the four notches; the mounting assembly comprises a support base fixedly connected to the inner wall of the back shell body, and the support base corresponds to the position of the notch, the side wall of the support base is slidably connected to a movable rod, one end of the movable rod passes through the back shell body and is connected to a circular block, a positioning hole is provided through the upper end of the L-shaped mounting rod, and a fastening bolt fixed to the external TV front shell is threaded in the positioning hole to facilitate the disassembly and assembly of the mounting plate and the TV front shell.

[0004] Although the existing technology can improve the convenience of installation, during the operation, a raised structure is provided for support and positioning operations. However, after long-term use, the raised structure may cause material fatigue, resulting in cracks or deformation, affecting the durability and stability of the back shell. The added raised structure reduces the versatility of the back shell, and the use of an L-shaped mounting rod and a positioning hole structure for installation makes the overall structure complex, increases the weight of the back shell, and makes the overall transportation inconvenient.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original assembled rear shell structure for televisions. Therefore, we propose an assembled rear shell structure for televisions that can well solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an assembled back shell structure for a television set to solve the problem of the raised structure currently set on the market for support and positioning operations proposed in the above-mentioned background technology. However, after long-term use, the raised structure may cause material fatigue, resulting in cracks or deformation, affecting the durability and stability of the back shell, and the added raised structure reduces the versatility of the back shell.

The first heat dissipation hole dissipates the heat generated inside the TV to avoid heat accumulation in the casing, thereby extending the service life of electronic components inside the TV and reducing the risk of failure due to overheating. When disassembly is required, hot air can be blown towards the first through hole to heat up the first metal sheet on the limit block, thereby causing the first metal piece at the end of the first metal piece to deform, so that the first metal piece can be easily removed from the front cover limit groove, thereby making the rear shell body easy to disassemble from the front cover of the TV.

The assembly screws are screwed in through the through holes, so that the rear shell body is conveniently and stably docked with the front cover of the television. This not only reduces the problem of the rear shell body loosening due to vibration factors, but also reduces the problem of increased weight caused by setting a cumbersome docking structure, thereby facilitating transportation operations.
