The top of the cell wall of described V-shaped groove is positioned on the incline of the second squared profile, and bottom land is positioned in the two opposite side surfaces of the second squared profile.
In the present invention, the technological scheme of squared profile linkage structure is:
squared profile linkage structure, comprise the first squared profile and the second squared profile, the butt end of described second squared profile offers V-shaped groove, in the two opposite side surfaces that the bottom land of described V-shaped groove is positioned at described second squared profile or on relative two inclines, the bottom land of described V-shaped groove is fixed to the corresponding incline of the first squared profile, the side of the cell wall of described V-shaped groove and the adjacent with described incline of the first squared profile is fixed
the top of the cell wall of described V-shaped groove is positioned on the incline of the second squared profile, and bottom land is positioned on the corresponding incline of the second squared profile.
The top of the cell wall of described V-shaped groove is positioned on the incline of the second squared profile, and bottom land is positioned in the two opposite side surfaces of the second squared profile.
Angle between the axis of described first squared profile and the axis of the second squared profile is 0 degree ~ 90 degree.
A kind of squared profile docking calculation that the present invention proposes and linkage structure, second squared profile offers V-shaped groove, V-shaped groove is fixed with two crossing sides of the first squared profile, make the bonding area of contact between the first squared profile and the second squared profile large, connect reliable, improve the structural strength of linkage structure, connecting means provided by the invention is simple, easy to operate; And the linkage structure adopting the method to form bonding area of contact large and due to second square on the bottom land of V-shaped groove and the incline of the first squared profile is fixed, adjacent two sides of this incline are fixed on cell wall and the first squared profile, therefore make at least the first squared profile slant setting, thus improve the resistance to flexure of whole linkage structure.
Further, make the bottom land of V-shaped groove be positioned on the incline of squared profile, the bonding area of contact further increased between the first squared profile and the second squared profile is large, improves glued construction intensity.
