Description

Technical Field

[0001] This utility model relates to the field of iron bed frame technology, specifically an iron bed frame that is easy to assemble and disassemble. Background Technology

[0002] As an essential piece of furniture in people's daily lives, the bed, used for rest and sleep, has different uses and cultural connotations in different social contexts. In ancient times, people slept on sturdy and beautifully designed beds. They covered the wooden, stone, or metal bed frames with animal hides and soft fabrics to increase comfort. Iron-framed beds, a type of bed with a metal structure (usually steel or alloy), are characterized by their durability, high space utilization, and simple style, and are widely used in homes, dormitories, hospitals, military camps, and other places.

[0003] Existing single-layer iron frame beds are inconvenient to disassemble after installation, causing inconvenience in use. Therefore, how to provide a single-layer iron frame bed that is easy to disassemble has become a problem that needs to be discussed and exchanged by people in this technical field.

[0004] Chinese Utility Model Patent Publication No. CN 214905321 U discloses a single-layer iron frame bed that is easy to disassemble. This bed features threaded connections between the first and second connecting pipes, the right-angle connecting pipe and the fourth and fifth connecting pipes, and threaded connections at both ends of the support legs, the first and second support rods, and one threaded connection at one end of the first and second connecting rods. These threads, combined with a third connecting pipe, connect the bed without the need for bolts and nuts, facilitating installation and disassembly. However, this single-layer iron frame bed relies solely on threaded connections between the connecting pipes. Repeated disassembly and reassembly can lead to wear or deformation of the threads, reducing connection reliability. Furthermore, the lack of an adjustable support leg structure makes it unsuitable for use in different terrains, resulting in poor practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an iron bed frame that is easy to assemble and disassemble, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: an iron bed frame that is easy to assemble and disassemble, including a headboard support and a footboard support. A folding component is fixedly installed at the bottom of both the headboard support and the footboard support. A support component is fixedly installed on the side of the folding component away from the headboard support and the footboard support.

[0007] The support assembly includes a support base. The end of the support base away from the headboard and footboard supports has a guide groove for positioning and installation. An extension seat is provided on the side of the guide groove away from the headboard and footboard supports.
