Abstract: A frame door with a split connection frame is provided, including a split connection frame. The split connection frame includes a first connection frame which is provided in a frame door and a second connection frame which is provided in an other frame door. The first connection frame is provided with a slide rail groove, the second frame is provided with a slide plate which engages with the slide rail groove. The slide rail groove has a C-shaped cross section so as to wrap edges of the slide plate.

Abstract: An assembled door frame is provided, including multiple of side frames spliced together, where every adjacent two of the side frames spliced at right angle are connected via a corner connector assembly. The corner connector assembly is arranged inside the every adjacent two of the side frames spliced at right angle. The corner connector assembly includes a corner connector and fixing bolts, and one of the every adjacent two of side frames spliced at right angle is fixed on the corner connector by the fixing bolts. In the embodiments, the side frames are spliced directly together through the respective corner connector assemblies each including the corner connector and the fixing bolts. On one hand, the corner connector and the fixing bolts are each disposed within the corresponding side frame, such that the original external structure of the side frames will not be changed after the side frames are spliced together, thereby reducing assembly errors of the door frame caused by using the connecting structure.

Abstract: A frame door with a split connection frame is provided, including a split connection frame. The split connection frame includes a first connection frame which is provided in a frame door and a second connection frame which is provided in an other frame door. The first connection frame is provided with a slide rail groove, the second frame is provided with a slide plate which engages with the slide rail groove. The slide rail groove has a C-shaped cross section so as to wrap edges of the slide plate. By using the split connection frame design, and using the sliding connection solution of slide rail groove and slide plate, on the one hand, the operation is convenient, time and labor are saved by the preset slide track during mounting process. On the other hand, the frame door is enable to be positioned in the mounting process via the preset slide track, thereby avoiding the assembly error caused by improper operation when using the existing mounting method and improving the assembly accuracy.
