Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7A frame mounting structure includes a column 1, a crossbeam 2, and a corner mounting assembly 3. The column 1 and the crossbeam 2 are both tubular structures. The corner mounting assembly 3 includes a liner 300 and an end cap 301. The liner 300 is inserted into the end of the crossbeam 2. An inclined plate 200 is provided inside the crossbeam 2. A first through hole 202 is provided on the inclined plate 200. A first screw hole 3001 corresponding to the first through hole 202 is provided on the liner 300. Both the first through hole 202 and the first screw hole 3001 are inclined. The first through hole 202 and the first screw hole 3001 are connected by a first bolt. An operating port 203 corresponding to the position of the inclined plate 200 is also provided on the shell wall of the crossbeam 2. The first bolt is hidden in the crossbeam 2. A second through hole 3002 is provided on the outer side of the liner 300. The end cap 301 is inserted into the end of the column 1. A second screw hole 3010 is provided on the side of the end cap 301 corresponding to the shell wall of the column 1. The second through hole 3002 and the second screw hole 3010 are connected by a second bolt, which is hidden in the crossbeam 2 and the column 1. A third through hole 100 is provided on the side wall of the column 1 facing the crossbeam 2 for the second bolt to pass through.

[0025] Continue reading Figures 1-6 In one embodiment of this utility model, the first through hole 202 and the first screw hole 3001 are at an angle of 20°-60° to the horizontal plane, preferably 30°.

[0026] Continue reading Figure 1 and Figure 2 In one embodiment of this utility model, the operating port 203 is horizontally arranged and located on the upper or lower side of the crossbeam 2.

[0027] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, a first inclined surface 3000 is provided on the lining 300, a second inclined surface 201 that fits against the first inclined surface 3000 is provided on the inclined plate 200, a first screw hole 3001 is provided on the first inclined surface 3000, and a first through hole 202 is provided on the second inclined surface 201.

[0028] Continue reading Figure 2 In one embodiment of this utility model, a plug 3003 is provided on the outer side of the inner liner 300, and a socket 3011 for mating with the plug 3003 is provided on the side wall of the end cap 301. With this structural design, this utility model can improve the connection reliability between the inner liner 300 and the end cap 301.

[0029] Continue reading Figure 1 and Figure 2 In one embodiment of this utility model, the second through hole 3002 and the second screw hole 3010 are both horizontally arranged along the crossbeam 2.

[0030] Continue reading Figures 3-6In one embodiment of this utility model, two second through holes 3002 are provided diagonally along the upper edge of the inner liner 300, and two second screw holes 3010 are provided diagonally along the upper edge of the end cap 301.
