Description

Technical Field

[0001] The present invention relates to a frame body that is easy for users to assemble.

Background Art

[0002] Conventional frames of frame bodies are mainly formed by connecting a plurality of pipes. The pipes are fixed by welding between the pipes or connected and fixed by pins or rivets; when welding and fixing a plurality of pipes, the two pipes to be connected must be positioned using jigs, and the construction cost required for welding is high. Moreover, the pipe group after welding and fixing cannot be disassembled, occupies a considerable amount of space, is disadvantageous for packaging and transportation, and is difficult to carry after being combined into a frame body and occupies a considerable amount of space. Furthermore, after disassembling, it cannot be combined into other forms of frame bodies; on the other hand, the pipe group after being connected by pins or rivets is also difficult to disassemble, occupies a considerable amount of space, and is disadvantageous for packaging and transportation. In addition, most of the bending parts of conventional frame bodies use vent pipes or a plurality of connecting pipes for welding and fixing. When packaging the vent pipes or the welded connecting pipe group together with other members of the conventional frame body, it occupies a considerable amount of space, the packaging size is large, the overall thickness of the packaging size cannot be reduced, and packaging and transportation are difficult.

[0003] Therefore, conventional frame bodies have drawbacks and defects such as being difficult to position when connecting pipes, difficult to disassemble, disadvantageous for packaging and transportation, and the members of conventional frame bodies being only suitable for assembling into a single form of frame body.
