Flat door frame

Abstract

Disclosed is a flat door frame. The flat door frame is composed of a hinge frame, an edge locking frame and an upper frame. The flat door frame does not need to be welded into a whole before being used but the components are conveyed to a destination site and then assembled into an integrated door frame. The components are small in size, light in weight and convenient to carry and meanwhile can belaminated in layout during lamination, so that a transport vehicle can achieve carriage capacity twice as much as that for integrated door frames to greatly reduce the transport cost. The flat door frame is free from welding joints and accordingly saves professional welding procedures, and during assembly, can be assembled into a qualified whole without professional workers. Therefore, the flat door frame can be lower in labor cost and production energy consumption cost than traditional integrated door frames, and further production enterprises can acquire significant economic benefits.

Description

technical field [0001] The invention belongs to a novel door frame, in particular to a flat frame door frame. Background technique [0002] The traditional door frame has many shapes and patterns, and the formed product has a large number of bending knives. It is a whole formed by combination, splicing and welding. Professional electric welding equipment and professional welders are required, the manufacturing process is complicated and cumbersome, and the solder joints are not beautiful, and the labor cost is high. [0003] Since the door frame is a formed combination, the door frame assembly is packaged, which takes up a lot of packaging materials and loading space. In addition, such a door frame is not only heavy during transportation, but also because it has been formed, it cannot be stacked in a good layout during the stacking process, and the transport vehicle cannot achieve the desired amount during the vehicle loading process, which greatly increases the transportat...

Problems solved by technology

Professional electric welding equipment and professional welders are required, the production process is complicated and cumbersome, and the solder joints are not beautiful, and the labor cost is high

[0003] Since the door frame is a formed combination, the door frame is assembled and packaged, which takes up a lot of packaging materials and loading space

In addition, such a door frame is not only heavy during transportation, but also because it has been formed, it cannot be stacked in a good layout during the stacking process, and the transport vehicle cannot achieve the desired amount during the vehicle loading process, which greatly increases the transportation cost. improve
