Welding-free and simply combined door frame combination

Abstract

A welding-free and simply combined door frame combination consists of a left frame, a right frame, a top frame, a bottom frame, a top frame fixing connector, a bottom frame fixing connecting rack, socket head cap screws and socket head cap screw protecting covers. Before a door frame is used, the door frame is not required to be welded into a formed indoor door. In a combining process of the door frame, the left frame and the right frame are respectively combined with the socket head cap screws and the socket head cap screw protecting covers to form a whole body, the top frame and the top frame fixing connector form a whole body, the bottom frame and the bottom frame fixing connecting rack also form a whole body, and therefore, when the left frame, the right frame, the top frame and the bottom frame are combined, a formed indoor door frame can be assembled quickly and stably by a screwdriver only. Because several scattered groups are small in size and light in weight, the groups are carried conveniently and easily, moreover, layout stacking can be implemented in a stacking process, the capacity of carriage of a conveying vehicle can be more than two times of the capacity of carriage of a conveying vehicle which carries formed door frames, and the conveying cost is greatly reduced.

Description

technical field [0001] The invention belongs to a door frame, in particular to a door frame assembly which is free of welding and simple to combine. Background technique [0002] The traditional interior door frame molding product is a whole formed by splicing and welding. Professional welding equipment and professional welders are required, and the production process is complex and cumbersome. [0003] Since the interior door frame is a formed assembly, such a door frame is not only bulky during transportation, but also because it has been formed, it cannot be well laid out and stacked during the stacking process. The ideal amount and greatly increase the shipping cost. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the shortcomings of the existing indoor door frame and provide a brand new door frame assembly that is free of welding and simple to combine. Specifically, the combination includes: a left frame (1), a right frame (2),...

Problems solved by technology

Professional electric welding equipment and professional welders are required, and the production process is complex and cumbersome

[0003] Since the interior door frame is a formed combination, such a door frame is not only bulky 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 reach Desirable amount and makes the shipping cost significantly higher
