[0016] A TV back panel 1, which is made of metal material and is provided with an integrally formed outer package 11, which is cylindrical and has riveting holes 12 on its inner wall;

[0017] A wall-mounted column 2 extends from the bottom of the outer package 11 into the riveting hole 12, a screw hole 21 is provided in the middle of the wall-mounted column 2, and a base 22 is provided. The wall-mounted column 2 is provided with a spaced-apart protrusion 23 above the base 22, and the protrusion 23 abuts against the inner wall of the outer package 11 and limits the rotation of the wall-mounted column 2.

[0018] In actual processing, the wall-mounted column 2 is driven in from the bottom of the TV back panel 1 and extends into the riveting hole 12, and then the convex portion 23 is set to achieve the preliminary positioning of the TV back panel 1 and the wall-mounted column 2, and then the riveting press realizes the combination of the outer package portion 11 and the wall-mounted column 2 through the deformation of the base 22. Further, through the combination of the convex portion 23 and the outer package portion 11, the bonding strength between the TV back panel 1 and the root of the wall-mounted column 2 can be effectively improved, and the loosening of the wall-mounted column 2 caused by exceeding the predetermined screwing force can be further avoided;

[0020] Specifically, the wall-mounted column 2 is made of free-cutting steel, and its outer wall is provided with a galvanized coating, thereby ensuring the rigidity of the wall-mounted column 2 and at the same time ensuring its corrosion resistance.

[0021] In the embodiment of the utility model, the protrusion 23 is in a sharp tooth shape, and under the action of riveting, the protrusion 23 is inserted into or stuck into the outer package 11.

[0022] Specifically, the protrusions 23 are distributed along the circumference of the outer wall of the wall-hanging column 2, and the side ends of two adjacent protrusions 23 are connected, so that the wall-hanging column 2 and the outer package portion 11 are in contact at any radial position, achieving stable riveting.

[0023] In the embodiment of the utility model, the wall-mounted column 2 is provided with a clamping portion 3 with a reduced diameter at the upper end of the protrusion 23. The diameter of the clamping portion 3 is smaller than the outer diameter of the wall-mounted column 2, further improving the connection stability between the back panel and the wall-mounted column 2.

[0024] Specifically, a horizontally extending flange portion 4 is provided at the upper end of the outer package portion 11 , and the flange portion 4 is in contact with the upper end wall of the wall-hanging column 2 , thereby achieving hiding and shielding of the wall-hanging column 2 .

[0025] In the embodiment of the utility model, the outer wall of the upper end of the wall-hanging column 2 is provided with a first chamfer 51, and the inner wall is provided with a second chamfer 52, wherein the first chamfer is used to make the flange portion 4 fit more gently with the wall-hanging column 2, and the second chamfer is used to facilitate the guiding of the screw.

[0026] Furthermore, the convex parts 23 are formed by rolling. In actual design, a rolling machine can be used to directly form the convex parts 23 with uniform distribution, wherein the convex parts 23 can be provided with multiple layers.
