An assembled metal protective frame

Abstract

The invention provides a spliced type metal protecting frame which comprises an outer frame, L-type connecting parts, T-type connecting parts, a cross-shaped connecting part, corner connectors and threaded rods. The outer frame is a square outer frame formed by four profiles in an enclosure mode. Every two profiles are connected through the corner connectors. The number of the L-type connecting parts is 4, and the L-type connecting parts are matched and connected with the four inner corners of the outer frame respectively; the number of the T-type connecting parts is 4, the T-type connecting parts are connected with the middle positions of the four profiles respectively, and the same two axial ends of the T-type connecting parts are connected with the L-type connecting parts at the two ends of the axial extending line respectively; the number of the cross-shaped connecting part is 1, the cross-shaped connecting part is located in the center in the outer frame, and the four ends of the cross-shaped connecting part are connected with the last ends of the T-type connecting parts through the threaded rods respectively. By the adoption of the frame, all the parts are connected closely, welding is not needed, assembling and disassembling are convenient, and the decorating and reinforcing effects of window frames, handrails and guard bars can be effectively improved.

Description

technical field [0001] The invention relates to the technical fields of doors, windows, railings, guardrail decoration and anti-theft, in particular to an assembled metal protective frame. Background technique [0002] In the fields of doors, windows, railings, and guardrails, spacers made of various materials such as aluminum alloy, plastic or plastic steel, steel, stainless steel, and ceramics have been widely used in buildings. The above-mentioned materials are used on frames that need to be decorated and strengthened, such as doors, windows, railings, and guardrails. It is widely used because of its considerable strength and aesthetics. [0003] At present, in construction projects, various doors and windows, railings, and guardrail frames are in various formats to make the overall effect of the building pleasing to the eye. The strips are either welded, or the connection strength between the spacers is not enough, it is inconvenient to assemble and disassemble, or the...
