Door frame splicing structure

Abstract

The invention discloses a door frame splicing structure. The door frame splicing structure comprises an upper transverse frame and borders. The upper transverse frame and the borders are the same in frame type. The two ends of the upper transverse frame and the upper ends of the borders are in butt joint at the 45-degree corner cut position, an attached part is arranged in a cavity in the butt joint position, the contour of one side face, making contact with the upper transverse frame and the borders, of the attached part is fit to the upper transverse frame and the borders, threaded holes are formed in the attached part, screws penetrate through the threaded holes, the attached part is fixedly connected with the upper transverse frame and the borders through the screws, a pattern is arranged on the other side face of the attached part and attached to the surface, contacted with the pattern, of the attached part, the figure shape of the pattern is matched with the figure shape of the upper transverse frame and the figure shape of the borders, and the pattern is fixedly connected with the attached part through the screws. The door frame splicing structure is simple in manufacturing process, the upper transverse frame and the left border and the right border of a spliced door can be conveniently mounted and demounted, transport and field splicing can be conveniently conducted, and stability of the shape of a frame of the spliced door can be accurately guaranteed through the attached part.

Description

technical field [0001] The invention belongs to the technical field of door manufacturing, in particular to a door frame assembly structure. Background technique [0002] The traditional high-end door frames are mostly welded, and the upper rail, the left frame and the right frame are welded and fastened as a whole. Due to its structural limitation, the process is complicated and the production is cumbersome, resulting in low production efficiency and unstable quality; Moreover, when leaving the factory, it needs to be assembled with the door leaf to form a whole door body for shipment. Due to the limitation of specifications and shapes, its volume and weight are large, and it is prone to damage such as knocking, scratching, jamming, and pressing during transportation, resulting in increased packaging and transportation costs. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a door frame assembly structure, ...
