[0023] The fixing part 1 is provided with fixing holes 101, the outer side of the fixing part 1 is provided with fillets 102, and a cavity 103 is provided between the fillets 102 and the fixing holes 101;

[0024] The assembly part 2 includes an assembly chute 201 arranged in a T-shaped structure. A notch groove 202 is provided at the inner center of the assembly chute 201. The notch groove 202 is arranged in a triangular structure. An assembly step 203 is provided on the outer side of the assembly chute 201;

[0025] The strengthening part 3 includes a strengthening slot hole 301 arranged in a rectangular structure. The strengthening slot hole 301 is arranged at the included angle between two assembly chutes 201.

[0026] In this embodiment, during use, the operator inserts the external profile frames of the two right-angled sides into the interior of the fixing part 1 by cooperating with the assembly part 2, so that the external profile frames are inserted into the assembly chute 201. When sliding, by adding lubricant in the notch groove 202, the sliding connection between the external profile frames and the fixing part 1 becomes smoother. When the external profile frames are installed into the fixing part 1 through the assembly chute 201, one side of the external profile frames in contact with the fixing part 1 will be installed into the assembly step 203, further improving the assembly effect.

[0027] Among them, the fixing hole 101 of the fixing part 1 is used for positioning and installation. The cavity 103 prevents deformation and makes the force evenly distributed. The strengthening slot hole 301 of the strengthening part 3 is used for positioning and cooperation, and increases the strength of the entire corner profile.
