Problems solved by technology

[0002] At present, the anti-theft doors used in people's lives have many improvements in shape, function and color patterns compared with the past, which brings great convenience to people's lives, but the structure of the door frame closely related to the door has not been improved. The gap between the door frame and the wall not only affects the installation firmness of the door frame and the wall, but also affects the overall aesthetic effect; so someone made an improvement on this, adding a circle of wrapping around the edge of the front panel of the door frame body to cover The gap between the door frame and the wall is covered, but this edging needs to be re-made after the door frame is installed, and then manually installed, which wastes manpower and material resources, and re-installs a edging, the surface is not smooth, the color It may also be inconsistent, affecting the overall aesthetics, and the existing door frames are mainly made of wood, which is prone to deformation and the overall weight is relatively heavy. There are also door frames prepared by bending sheet metal, but the deformation resistance is poor

Abstract

The invention relates to the field of anti-theft doors, in particular to a pre-installed door frame, which comprises an upper transom bar, a lower transom bar, two vertical columns arranged between the upper transom bar and the lower transom bar, and a door head arranged at the upper end of the upper transom bar. The vertical column comprises a first profile with an L-type cross section, and a first bend for shielding a door seam is located at the inner side of the door body and arranged on the first wing of the first profile; the upper transom bar comprises a second profile with an upward U-type cross section, and a second bend for shielding a door seam is located at the inner side of the door body and arranged on the lower end of the second profile; and the lower transom bar comprises athird profile with a downward U-type cross section, and a third bend for shielding a door seam is located at the inner side of the door body and arranged on the upper end of the third profile. Thus, the door seam can be shielded, the overall weight is lightened, and installation is facilitated.
